1. Burnout and Satisfaction with Work-Life Balance Among US Physicians Relative to the General US Population 

Shanafelt TD, et al. Arch Intern Med. 2012;172(18):1-9.  

Background  Despite extensive data about physician burnout, to our knowledge, no national study has evaluated rates of burnout among US physicians, explored differences by specialty, or compared physicians with US workers in other fields. 

Methods  We conducted a national study of burnout in a large sample of US physicians from all specialty disciplines using the American Medical Association Physician Masterfile and surveyed a probability-based sample of the general US population for comparison. Burnout was measured using validated instruments. Satisfaction with work-life balance was explored. 

Results  Of 27 276 physicians who received an invitation to participate, 7288 (26.7%) completed surveys. When assessed using the Maslach Burnout Inventory, 45.8% of physicians reported at least 1 symptom of burnout. Substantial differences in burnout were observed by specialty, with the highest rates among physicians at the front line of care access (family medicine, general internal medicine, and emergency medicine). Compared with a probability-based sample of 3442 working US adults, physicians were more likely to have symptoms of burnout (37.9% vs 27.8%) and to be dissatisfied with work-life balance (40.2% vs 23.2%) (P less than .001 for both). Highest level of education completed also related to burnout in a pooled multivariate analysis adjusted for age, sex, relationship status, and hours worked per week. Compared with high school graduates, individuals with an MD or DO degree were at increased risk for burnout (odds ratio [OR], 1.36; P less than .001), whereas individuals with a bachelor's degree (OR, 0.80; P = .048), master's degree (OR, 0.71; P = .01), or professional or doctoral degree other than an MD or DO degree (OR, 0.64; P = .04) were at lower risk for burnout. 

Conclusions  Burnout is more common among physicians than among other US workers. Physicians in specialties at the front line of care access seem to be at greatest risk. 

2. Cardiac Evaluation for Structural Abnormalities May Not Be Required in Patients Presenting With Syncope and a Normal ECG Result in an Observation Unit Setting 

Anderson KL, et al. Ann Emerg Med. 2012;60: 478-484.e1 

Study objective: Patients with syncope are frequently managed in observation units and receive serial examinations, monitoring for arrhythmias, and structural analysis of the heart. The primary aim of this study is to determine the utility of structural analysis of the heart in syncope patients who are being managed in an observation unit and have a normal ECG result. 

Methods: This is a retrospective, observational chart review of all consecutive adult patients observed during 18 months at an urban, academic medical center. A case report form with demographics, ECG interpretations, and structural analysis of the heart data was generated and all variables were defined before data extraction. Subjects with an ECG demonstrating any arrhythmia, premature atrial contraction, premature ventricular contraction, pacing, second- and third-degree blocks, and left bundle branch block were excluded from the normal ECG group. An abnormal cardiac structure was defined as an ejection fraction less than 45%, severe hypertrophy, or severe valvular abnormality. Ten percent of cases were evaluated by a second extractor to verify accuracy. Descriptive statistics with confidence intervals (CIs) and interquartile ranges (IQRs; 25%, 75%) are used. 

Results: Three hundred twenty-three subjects were managed in the observation unit for syncope, 48% were men, and their median age was 66 years (25%, 75% IQR 52, 80). Two of 323 (0.6%; 95% CI 0.2% to 2.2%) had an arrhythmia; 1 of 323 had a non–ST-segment myocardial infarction (0.3%; 95% CI 0.1% to 1.7%). Of the 323 patients, 267 had a normal ECG result and 235 (88%) had their cardiac structure evaluated. Forty-eight percent of the normal ECG group were men, and the median age was 65 years (25%, 75% IQR 52, 79). Zero of 235 patients (0%; 95% CI 0% to 1.6%) had a structural abnormality identified on evaluation, and 2 of 18 (11%; 95% CI 3.1% to 32.8%) had an abnormal stress echocardiogram result. 

Conclusion: Structural abnormalities are unlikely in syncope patients with a normal ECG result. Care should focus on excluding arrhythmias and acute coronary syndrome. 

3. Interactive Case from NEJM: A Complex Cause of Pleuritic Chest Pain 

McMahon GT, et al. N Engl J Med 2012; 367:e2. 

A 33-year-old man presented with pain on the right side of his chest that had started 5 days earlier and continued to worsen until the time of presentation. The pain originated near his right scapula and progressively radiated throughout his right chest. It did not worsen with movement of his arm or shoulder but did worsen with deep inspiration and when he was lying down. The patient . . . .

4. Dedicated Hospital Observation Units Could Save $3.1 Billion 

Steven Fox. Medscape Medical News. September 28, 2012 — Maximizing the potential use of dedicated hospital observation units could save billions of dollars in healthcare resources annually, according to results from a study published online September 26 and in the October issue of Health Affairs. 

Observation units (OUs) in hospitals provide an alternative to admitting patients who have received care in emergency departments but cannot yet be sent home safely. OUs are most often dedicated spaces, within or adjacent to emergency departments, where patients receive care, usually for less than 24 hours. 

"Observation unit care is an established and well-studied health care delivery model that is more cost-efficient than inpatient care for specific patient populations," Christopher W. Baugh, MD, from the Brigham and Women's Hospital Department of Emergency Medicine, Boston, Massachusetts, and colleagues write. The researchers note that previous studies have compared only single-site costs of observational care with routine inpatient care. "However, we are unaware of any prior attempts to quantify the potential financial impact of observation unit expansion," they write. 

"Our objective was to quantify the potential cost savings from a decrease in avoidable inpatient admissions that would result from increasing the use of observation units in eligible hospitals," they add. 

The researchers first conducted a literature review and then coupled that with national survey data to pinpoint how much money OU care saves per patient visit. The researchers used a Monte Carlo simulation to quantify the gap between current use of OUs and potential maximum use of such units. According to their analysis, OUs saved about $1572 ± $812 per hospital visit, compared with inpatient care. 

Using the Monte Carlo simulation model to extrapolate those savings out to the national level, the authors estimated that if all hospitals nationwide set up OUs, the cost savings would be $3.1 billion ± $1.9 billion. 

The researchers also estimate that setting up OUs would help avoid about 2.4 million ± 490,000 inpatient admissions each year. 

"For an average hospital with the visit volume to justify operating an observation unit, the annual direct cost savings would be $4.6 million (standard deviation: ±$2.9 million) from maximum use, resulting from about 3,600 (standard deviation: ±740) inpatient admissions avoided each year," they write. 

The researchers emphasize that their study focused on use of OUs that provide limited lengths of stay (usually less than 24 hours), rather than OUs that keep patients longer. "Patients are at much lower risk for excessive out-of-pocket costs when observation is used in this way," they note. 

In conclusion, they write, "Observation units represent a feasible care innovation worthy of further evaluation. The wider use of observation units may create cost savings and should be a model for acute care redesign to increase value in the US health care system."

5. Non-traumatic SAH in the setting of negative cranial CT: External validation of a clinical and imaging prediction rule. 

Mark DG, et al, for the Kaiser Permanente CREST Network Investigators. Ann Emerg Med. 2012 October 1 [Epub ahead of print] 

Study objective: Clinical variables can reliably exclude a diagnosis of nontraumatic subarachnoid hemorrhage in patients with negative cranial computed tomography (CT) results. We externally validated 2 decision rules with 100% reported sensitivity for a diagnosis of subarachnoid hemorrhage, among patients undergoing lumbar puncture after a negative cranial CT result: (1) clinical rule: presence of any combination of age 40 years and older, neck pain or stiffness, loss of consciousness, or headache onset during exertion; and (2) imaging rule: cranial CT performed within 6 hours of headache onset. 

Methods: This was a matched case-control study of patients presenting to 21 emergency departments between 2000 and 2011. Patients with a diagnosis of subarachnoid hemorrhage as determined by lumbar puncture after a negative cranial CT result were screened for inclusion. A matched control cohort was selected among patients with a diagnosis of headache after negative cranial CT and lumbar puncture results. 

Results: Fifty-five cases of subarachnoid hemorrhage meeting inclusion criteria were identified, 34 (62%) of which were attributed to cerebral aneurysms. External validation of the clinical rule demonstrated a sensitivity of 97.1% (95% confidence interval [CI] 88.6% to 99.7%), a specificity of 22.7% (95% CI 16.6% to 29.8%), and a negative likelihood ratio of 0.13 (95% CI 0.03 to 0.61) for a diagnosis of subarachnoid hemorrhage. External validation of the imaging rule revealed that 11 of 55 subarachnoid hemorrhage cases (20%) had negative cranial CT results for tests performed within 6 hours of headache onset. 

Conclusion: The clinical rule demonstrated useful Bayesian test characteristics when retrospectively validated against this patient cohort. The imaging rule, however, failed to identify 20% of subarachnoid hemorrhage patients with a negative cranial CT result. 

Excerpt from the discussion: Although cranial CT or clinical prediction rules alone do not clearly and safely achieve these ideal test performance goals, the combined application of both testing strategies might offer an improvement. Even with a very conservative estimated subarachnoid hemorrhage risk of 1.25% (1 of 80 risk) after negative cranial CT, the application of the 4-item decision rule derived by Perry et al, even with a negative likelihood ratio as high as 0.13 as reported in this study, can reduce this incidence to 0.2%, or 1 in 500 patients. Additionally, given that the specificity for the rule in this study was validated against a population of patients who uniformly underwent cerebrospinal fluid analysis, application of the clinical rule after negative cranial CT result has the potential to reduce rates of lumbar puncture by approximately 25%. 

[DRV: Pearl for clinical application: In cases of suspected SAH, if CT negative, assess for these 4 risk factors:
·         Loss of consciousness
·         Exertional onset of headache
·         Age  40 years or older
·         Neck pain or stiffness 

If CT negative and LEAN negative you can safely skip LP in the work up of suspected atraumatic SAH.] 

6. Physicians' Warnings for Unfit Drivers and the Risk of Trauma from Road Crashes 

Redelmeier DA, et al. N Engl J Med 2012; 367:1228-1236.  

Background: Physicians' warnings to patients who are potentially unfit to drive are a medical intervention intended to prevent trauma from motor vehicle crashes. We assessed the association between medical warnings and the risk of subsequent road crashes. 

Methods: We identified consecutive patients who received a medical warning in Ontario, Canada, between April 1, 2006, and December 31, 2009, from a physician who judged them to be potentially unfit to drive. We excluded patients who were younger than 18 years of age, who were not residents of Ontario, or who lacked valid health-card numbers under universal health insurance. We analyzed emergency department visits for road crashes during a baseline interval before the warning and a subsequent interval after the warning. 

Results: A total of 100,075 patients received a medical warning from a total of 6098 physicians. During the 3-year baseline interval, there were 1430 road crashes in which the patient was a driver and presented to the emergency department, as compared with 273 road crashes during the 1-year subsequent interval, representing a reduction of approximately 45% in the annual rate of crashes per 1000 patients after the warning (4.76 vs. 2.73, P less than 0.001). The lower rate was observed across patients with diverse characteristics. No significant change was observed in subsequent crashes in which patients were pedestrians or passengers. Medical warnings were associated with an increase in subsequent emergency department visits for depression and a decrease in return visits to the responsible physician. 

Conclusions: Physicians' warnings to patients who are potentially unfit to drive may contribute to a decrease in subsequent trauma from road crashes, yet they may also exacerbate mood disorders and compromise the doctor–patient relationship.

7. Revisiting a Prediction Rule for Identifying Children at Low Risk for Appendicitis 

Even after refinement, the rule is not sufficient for excluding this common diagnosis. 

A previously published prediction rule developed at a single center classifies children as having low risk for appendicitis if they meet the following criteria: absolute neutrophil count 6.75 x 103/µL, absence of nausea, and absence of maximal tenderness in the right lower quadrant (RLQ). The rule yielded a sensitivity of 98% and specificity of 32%. Now, the investigators validated and refined the rule in a prospective cohort of 2625 children (age range, 3 to 18 years; mean, 11 years) who presented to 9 pediatric emergency departments during 1 year with abdominal pain of less than 96 hours duration and suspected appendicitis. 

Overall, 1018 patients (39%) were diagnosed with appendicitis, and of these, 275 (27%) had a perforated appendix. Computed tomography was performed in 55% of patients, ultrasound in 37%, and both in 12%. The negative appendectomy rate was 9% (95 patients). Had the rule been applied, 22 unnecessary operations would have been prevented, but 42 patients with appendicitis would have been missed (sensitivity, 96%; specificity, 36%). A refined rule, consisting of absolute neutrophil count 6.75 x 103/µL and either no maximal tenderness in the RLQ or maximal tenderness in the RLQ and no abdominal pain with walking, jumping, or coughing, identified 400 patients as having low risk for appendicitis. The refined rule would have missed 19 patients with appendicitis, yielding a sensitivity of 98% and specificity of 24%. 

Comment: The investigators failed to compare performance between these rules and clinical suspicion for appendicitis based on physical examination alone. Overall clinical gestalt should still be the basis for identifying children at low risk for appendicitis. When the diagnosis is uncertain, investigation should begin with ultrasound, followed by computed tomography if ultrasound is nondiagnostic.

8. Ask Suicide-Screening Questions (ASQ)A Brief Instrument for the Pediatric Emergency Department 

Horowitz LM, et al. Arch Pediatr Adolesc Med. 2012 Oct 1:1-7.  

Objective  To develop a brief screening instrument to assess the risk for suicide in pediatric emergency department patients. 

Design  A prospective, cross-sectional instrument-development study evaluated 17 candidate screening questions assessing suicide risk in young patients. The Suicidal Ideation Questionnaire served as the criterion standard. 

Setting  Three urban, pediatric emergency departments associated with tertiary care teaching hospitals. 

Participants  A convenience sample of 524 patients aged 10 to 21 years who presented with either medical/surgical or psychiatric chief concerns to the emergency department between September 10, 2008, and January 5, 2011. 

Main Exposures  Participants answered 17 candidate questions followed by the Suicidal Ideation Questionnaire. 

Main Outcome Measures  Sensitivity, specificity, predictive values, likelihood ratios, and area under the receiver operating characteristic curves of the best-fitting combinations of screening questions for detecting elevated risk for suicide. 

Results  A total of 524 patients were screened (344 medical/surgical and 180 psychiatric). Fourteen of the medical/surgical patients (4%) and 84 of the psychiatric patients (47%) were at elevated suicide risk on the Suicidal Ideation Questionnaire. Of the 17 candidate questions, the best-fitting model comprised 4 questions assessing current thoughts of being better off dead, current wish to die, current suicidal ideation, and past suicide attempt. This model had a sensitivity of 96.9% (95% CI, 91.3-99.4), specificity of 87.6% (95% CI, 84.0-90.5), and negative predictive values of 99.7% (95% CI, 98.2-99.9) for medical/surgical patients and 96.9% (95% CI, 89.3-99.6) for psychiatric patients. 

Conclusions  A 4-question screening instrument, the Ask Suicide-Screening Questions (ASQ), with high sensitivity and negative predictive value, can identify the risk for suicide in patients presenting to pediatric emergency departments. 

9. IV Dextrose for Kids with Gastroenteritis and Dehydration? 

By Will Boggs, MD. Reuters Health Information. NEW YORK (Reuters Health) Sep 27 - An initial bolus of 5% dextrose in normal saline does not reduce hospitalization rates in children with gastroenteritis and dehydration, but it does reduce serum ketone levels, researchers say. And that may influence the decision to admit. 

"Those kids with low serum bicarbonate (the acidosis from the high ketones) are the exact ones in which we think the extra glucose can help," said Dr. Jason A. Levy from Children's Hospital Boston in email to Reuters Health. "But if they are being admitted because of their low bicarbonate (even if clinically improved), then we may have been unable to show a true improvement with our outcome measure." 

"We also saw that among the kids with acidosis, those who received the dextrose bolus required follow-up less than those who received the normal saline bolus (33% versus 11%)," Dr. Levy said. "Although this difference was not statistically significant (p=0.09), we feel like these kids may have benefited from the extra dextrose." 

In a randomized trial, Dr. Levy and colleagues compared the effects of a 20ml/kg infusion of either 5% dextrose in normal saline or normal saline solution alone on hospitalization rates and serum ketone levels in 188 children, ages six months to six years, who presented to the emergency department (ED) with gastroenteritis and dehydration. The children could receive additional oral or IV rehydration therapy at the discretion of the treating attending physician. Just over half (55%) of the children randomized to normal saline solution later received some IV dextrose during their ED visit. 

According to results published September 10th online in Annals of Emergency Medicine, there was no significant difference in the main outcome: 35% of children assigned to IV dextrose were hospitalized, compared with 44% of children assigned to IV normal saline. Hospitalization rates were also similar in the subset of children with acidosis (46% with IV dextrose, 53% with IV normal saline). 

Serum ketone levels, a secondary endpoint, declined by a significantly greater extent at one hour in the IV dextrose group than in the IV normal saline group (1.2 vs 0.1 mmol/L decrease). The difference was also significant at two hours (1.9 vs 0.3 mmol/L, respectively). Children who received IV dextrose were less likely than children who received IV normal saline to require unscheduled medical care, but this difference did not reach statistical significance. Neither group experienced adverse events, according to the authors. 

"I think the studies addressing the efficacy of oral rehydration therapy (ORT), both with and without ondansetron, have been fairly conclusive," Dr. Levy said. "Simply put, ORT works and we probably underutilize it in this country for a variety of reasons (lack of knowledge, parental and primary care physician expectations, etc)." 

"As you can see from our study," he added, "the jury may still be out on the best way to intravenously rehydrate these children, both in terms of the solution type and amount, although dextrose should play a role."

"I still have strong opinions around caring for these children, which are grounded in both my personal experience and reviews of the existing literature," Dr. Levy continued. "Looking at our study with all the existing data - the main message for me - dextrose should clearly be in the algorithm when treating kids with gastroenteritis and dehydration. By using IV dextrose, there is a significant decrease in ketones which should make children feel better. Future studies should determine the optimal regimen with respect to fluid type and amount."

10. 613 cases of splenic rupture without risk factors or previously diagnosed disease: a systematic review 

FK Aubrey-Bassler and Nicholas Sowers.  BMC Emergency Medicine 2012, 12:11 doi:10.1186/1471-227X-12-11 

Background: Rupture of the spleen in the absence of trauma or previously diagnosed disease is largely ignored in the emergency literature and is often not documented as such in journals from other fields. We have conducted a systematic review of the literature to highlight the surprisingly frequent occurrence of this phenomenon and to document the diversity of diseases that can present in this fashion. 

Methods: Systematic review of English and French language publications catalogued in Pubmed, Embase and CINAHL between 1950 and 2011. 

Results: We found 613 cases of splenic rupture meeting the criteria above, 327 of which occurred as the presenting complaint of an underlying disease and 112 of which occurred following a medical procedure. Rupture appeared to occur spontaneously in histologically normal (but not necessarily normal size) spleens in 35 cases and after minor trauma in 23 cases. Medications were implicated in 47 cases, a splenic or adjacent anatomical abnormality in 31 cases and pregnancy or its complications in 38 cases. 

The most common associated diseases were infectious (n = 143), haematologic (n = 84) and non-haematologic neoplasms (n = 48). Amyloidosis (n = 24), internal trauma such as cough or vomiting (n = 17) and rheumatologic diseases (n = 10) are less frequently reported. Colonoscopy (n = 87) was the procedure reported most frequently as a cause of rupture. The anatomic abnormalities associated with rupture include splenic cysts (n = 6), infarction (n = 6) and hamartomata (n = 5). Medications associated with rupture include anticoagulants (n = 21), thrombolytics (n = 13) and recombinant G-CSF (n = 10). Other causes or associations reported very infrequently include other endoscopy, pulmonary, cardiac or abdominal surgery, hysterectomy, peliosis, empyema, remote pancreato-renal transplant, thrombosed splenic vein, hemangiomata, pancreatic pseudocysts, splenic artery aneurysm, cholesterol embolism, splenic granuloma, congenital diaphragmatic hernia, rib exostosis, pancreatitis, Gaucher's disease, Wilson's disease, pheochromocytoma, afibrinogenemia and ruptured ectopic pregnancy.  

Conclusions: Emergency physicians should be attuned to the fact that rupture of the spleen can occur in the absence of major trauma or previously diagnosed splenic disease. The occurrence of such a rupture is likely to be the manifesting complaint of an underlying disease. Furthermore, colonoscopy should be more widely documented as a cause of splenic rupture.  


11. Small-bore catheter versus chest tube drainage for pneumothorax 

Contou D, et al. Amer J Emerg Med 2012;30:1407-1413.  

Study Objective: The aim of the study was to compare the effectiveness of drainage via a single-lumen (5F catheter) central venous catheter (CVC) to a conventional (14-20F catheter) chest tube (CT) for the management of pneumothoraces, including primary spontaneous pneumothorax (PSP), secondary spontaneous pneumothorax (SSP), and traumatic and iatrogenic pneumothoraces. 

Patients: All consecutive patients admitted to the intermediate intensive care unit of a university hospital for pneumothorax were retrospectively screened over an 8-year period. Patients were preferentially treated using CT from 2003 to 2007 and using CVC from 2008 to 2010. Drainage failure was defined as the need for a second drainage procedure or for surgery.

Results: Of 212 patients included, 117 (55%) had PSP, 28 (13%) had SSP associated with chronic obstructive pulmonary disease, 19 (9%) had traumatic pneumothorax, and 48 (23%) had iatrogenic pneumothorax. The failure rate was 23% in PSP, 36% in SSP, 16% in traumatic pneumothorax, and only 2% in iatrogenic pneumothorax. After adjustment, iatrogenic pneumothorax was the only factor that had an influence on drainage failure. The failure rate was similar between the 112 patients treated using CVC and the 100 patients treated using CT (18% vs 21%, P = .60). However, the durations of drainage (3.3 ± 1.9 vs 4.6 ± 2.6 days, P less than .01) and of hospital stay were significantly shorter in patients treated using CVC as compared with CT. 

Conclusion: Our findings suggest that drainage via a catheter or via a CT is similarly effective in the management of pneumothorax. We recommend considering drainage via a small-bore catheter as a first-line treatment in patients with pneumothorax, whatever its cause. 

12. Intraaortic Balloon Support for MI with Cardiogenic Shock 

Thiele H, et al. for the IABP-SHOCK II Trial Investigators. N Engl J Med 2012; 367:1287-1296  

In this trial, patients with acute MI and cardiogenic shock who were expected to undergo coronary revascularization were randomly assigned to receive or not to receive intraaortic balloon support. Balloon support had no effect on 30-day mortality. 

Background: In current international guidelines, intraaortic balloon counterpulsation is considered to be a class I treatment for cardiogenic shock complicating acute myocardial infarction. However, evidence is based mainly on registry data, and there is a paucity of randomized clinical trials. 

Methods: In this randomized, prospective, open-label, multicenter trial, we randomly assigned 600 patients with cardiogenic shock complicating acute myocardial infarction to intraaortic balloon counterpulsation (IABP group, 301 patients) or no intraaortic balloon counterpulsation (control group, 299 patients). All patients were expected to undergo early revascularization (by means of percutaneous coronary intervention or bypass surgery) and to receive the best available medical therapy. The primary efficacy end point was 30-day all-cause mortality. Safety assessments included major bleeding, peripheral ischemic complications, sepsis, and stroke. 

Results: A total of 300 patients in the IABP group and 298 in the control group were included in the analysis of the primary end point. At 30 days, 119 patients in the IABP group (39.7%) and 123 patients in the control group (41.3%) had died (relative risk with IABP, 0.96; 95% confidence interval, 0.79 to 1.17; P=0.69). There were no significant differences in secondary end points or in process-of-care measures, including the time to hemodynamic stabilization, the length of stay in the intensive care unit, serum lactate levels, the dose and duration of catecholamine therapy, and renal function. The IABP group and the control group did not differ significantly with respect to the rates of major bleeding (3.3% and 4.4%, respectively; P=0.51), peripheral ischemic complications (4.3% and 3.4%, P=0.53), sepsis (15.7% and 20.5%, P=0.15), and stroke (0.7% and 1.7%, P=0.28). 

Conclusions: The use of intraaortic balloon counterpulsation did not significantly reduce 30-day mortality in patients with cardiogenic shock complicating acute myocardial infarction for whom an early revascularization strategy was planned.

13. Risk factors for unplanned transfer to intensive care within 24 hours of admission from the ED in an integrated healthcare system 

Delgado MK, et al. J Hosp Med 2012 Sept 28 [Epub ahead of print] 

BACKGROUND: Emergency department (ED) ward admissions subsequently transferred to the intensive care unit (ICU) within 24 hours have higher mortality than direct ICU admissions. 

DESIGN, SETTING, PATIENTS: Describe risk factors for unplanned ICU transfer within 24 hours of ward arrival from the ED. 

METHODS: Evaluation of 178,315 ED non-ICU admissions to 13 US community hospitals. We tabulated the outcome of unplanned ICU transfer by patient characteristics and hospital volume. We present factors associated with unplanned ICU transfer after adjusting for patient and hospital differences in a hierarchical logistic regression. 

RESULTS: There were 4252 (2.4%) non-ICU admissions transferred to the ICU within 24 hours. Admitting diagnoses most associated with unplanned transfer, listed by descending prevalence were: pneumonia (odds ratio [OR] 1.5; 95% confidence interval [CI] 1.2–1.9), myocardial infarction (MI) (OR 1.5; 95% CI 1.2–2.0), chronic obstructive pulmonary disease (COPD) (OR 1.4; 95% CI 1.1–1.9), sepsis (OR 2.5; 95% CI 1.9–3.3), and catastrophic conditions (OR 2.3; 95% CI 1.7–3.0). Other significant predictors included: male sex, Comorbidity Points Score above 145, Laboratory Acute Physiology Score ≥7, arriving on the ward between 11 PM and 7 AM. Decreased risk was found with admission to monitored transitional care units (OR 0.83; 95% CI 0.77–0.90) and to higher volume hospitals (OR 0.94 per 1,000 additional annual ED inpatient admissions; 95% CI 0.91–0.98). 

CONCLUSIONS: ED patients admitted with respiratory conditions, MI, or sepsis are at modestly increased risk for unplanned ICU transfer and may benefit from better triage from the ED, earlier intervention, or closer monitoring to prevent acute decompensation. More research is needed to determine how intermediate care units, hospital volume, time of day, and sex affect unplanned ICU transfer.  

14. BMJ Meta-analysis Suggests Progesterone Level May ID Nonviable Pregnancies 

By Todd Neale, Senior Staff Writer, MedPage Today. September 27, 2012 

Among women who have bleeding or pain and an inconclusive ultrasound scan in early pregnancy, a single serum progesterone test may be able to identify those who are likely to miscarry or who have an ectopic pregnancy, a meta-analysis showed. 

In a pooled analysis, a single test with a threshold of 3.2 to 6 ng/mL predicted a nonviable pregnancy with a sensitivity of 74.6% and a specificity of 98.4%, according to Ioannis Gallos, MD, of the University of Oxford in England, and colleagues. The risk of a nonviable pregnancy was 99.2% when progesterone levels were below the cutoff and 44.8% when they were above the cutoff, the researchers reported online in BMJ. 

The progesterone test could not, however, distinguish between an ectopic pregnancy and a miscarriage. Serial serum β human chorionic gonadotropin measurements are needed for that purpose.  

The researchers said that a progesterone test could serve in a complementary role for women presenting with pain or bleeding early in pregnancy. "This test could be added to the existing algorithms for evaluation of early pregnancy, and its effect should be evaluated through a randomized trial comparing algorithms with and without serum progesterone," they wrote. 

Vaginal bleeding and abdominal pain are common early in pregnancy, with about 30% of women reporting those symptoms in the first trimester. Most women with those symptoms will undergo a transvaginal ultrasound to explore the problem, but that might not be enough to determine whether the pregnancy is viable. 

A progesterone test has been proposed to help make the diagnosis because low levels are associated with miscarriages and ectopic pregnancies. To assess the diagnostic accuracy of such a test, the researchers reviewed data from 26 cohort studies that included a total of 9,436 women with a pregnancy of less than 14 weeks gestation; seven of the studies included women with pain or bleeding plus an inconclusive ultrasound result and 19 included women with the symptoms alone. Meta-analysis revealed a high degree of accuracy for a single serum progesterone test to rule out a viable pregnancy in women with symptoms and an inconclusive ultrasound result. 

Diagnostic accuracy, however, was not as high among the women with symptoms alone. In those women, the progesterone test -- using a cutoff of 10 ng/mL -- predicted nonviable pregnancies with a pooled sensitivity of 66.5%, and a specificity of 96.3%. 

The median prevalence of nonviable pregnancy was 62.9%, a rate that increased to 96.8% when the progesterone level was below 10 ng/mL and dropped to 37.2% when the progesterone level was above the cutoff.

15. Inviting Patients to Read Their Doctors' Notes: A Quasi-experimental Study and a Look Ahead 

Delbanco T, et al. Ann Intern Med. 2 October 2012;157(7):461-470  

Background: Little information exists about what primary care physicians (PCPs) and patients experience if patients are invited to read their doctors' office notes. 

Objective: To evaluate the effect on doctors and patients of facilitating patient access to visit notes over secure Internet portals. 

Design: Quasi-experimental trial of PCPs and patient volunteers in a year-long program that provided patients with electronic links to their doctors' notes. 

Setting: Primary care practices at Beth Israel Deaconess Medical Center (BIDMC) in Massachusetts, Geisinger Health System (GHS) in Pennsylvania, and Harborview Medical Center (HMC) in Washington. 

Participants: 105 PCPs and 13 564 of their patients who had at least 1 completed note available during the intervention period.

Measurements: Portal use and electronic messaging by patients and surveys focusing on participants' perceptions of behaviors, benefits, and negative consequences. 

Results: 11 797 of 13 564 patients with visit notes available opened at least 1 note (84% at BIDMC, 92% at GHS, and 47% at HMC). Of 5391 patients who opened at least 1 note and completed a postintervention survey, 77% to 87% across the 3 sites reported that open notes helped them feel more in control of their care; 60% to 78% of those taking medications reported increased medication adherence; 26% to 36% had privacy concerns; 1% to 8% reported that the notes caused confusion, worry, or offense; and 20% to 42% reported sharing notes with others. The volume of electronic messages from patients did not change. After the intervention, few doctors reported longer visits (0% to 5%) or more time addressing patients' questions outside of visits (0% to 8%), with practice size having little effect; 3% to 36% of doctors reported changing documentation content; and 0% to 21% reported taking more time writing notes. Looking ahead, 59% to 62% of patients believed that they should be able to add comments to a doctor's note. One out of 3 patients believed that they should be able to approve the notes' contents, but 85% to 96% of doctors did not agree. At the end of the experimental period, 99% of patients wanted open notes to continue and no doctor elected to stop. 

Limitations: Only 3 geographic areas were represented, and most participants were experienced in using portals. Doctors volunteering to participate and patients using portals and completing surveys may tend to offer favorable feedback, and the response rate of the patient surveys (41%) may further limit generalizability. 

Conclusion: Patients accessed visit notes frequently, a large majority reported clinically relevant benefits and minimal concerns, and virtually all patients wanted the practice to continue. With doctors experiencing no more than a modest effect on their work lives, open notes seem worthy of widespread adoption.

16. Bilateral Anterior Dislocation of the Shoulder: Review of Seventy Cases and Proposal of a New Etiological-mechanical Classification 

Ballesteros R, et al. J Emerg Med. 2012; in press 

Background: Although anterior shoulder dislocation is common in everyday practice in Emergency Departments, bilateral presentation is a rare entity. 

Objectives: The aim of this article is to report two additional cases of this rare injury and to introduce a new mechanism that can produce it. We made an exhaustive review of the literature and found 68 cases in printed publications. Also, we analyzed the mechanism of injury and the presence of predisposing factors, and propose a new etiological-mechanical classification. 

Case Report: One case occurred after a trivial fall, and the other was produced by a mechanism not previously reported: the patient pushed strongly forward, expecting a resistance and finding none, his arms kept the forward movement and the shoulders dislocated. 

Discussion: This lesion has a bimodal distribution, affecting mainly men (70%) with a mean age of 33.5 years, whereas in women, the average age is 57 years. The most common cause is trauma (50%), followed by muscle contractions (37%) due to seizures of different causes (epileptic, hypoglycemia, toxic, or hypoxic) or electrocution. In 15.7% of the cases, the diagnosis of bilateral anterior dislocation was not acute (less than 3 weeks), and in virtually all of these cases it was not traumatic. 

Conclusion: The bilateral anterior shoulder dislocation may not be as rare as previously thought and must be taken into account in emergency services. The authors propose a new etiological-mechanical classification. Also, the importance of radiologic diagnosis must be highlighted. 

17. Sepsis Update: Management of Severe Sepsis and Septic Shock In The ED After The Withdrawal Of Xigris 

Green RS, et al. CJEM 2012;14(5):265-266 

Xigris, a systemic anticoagulant used for the management of patients with severe sepsis and septic shock, has recently been removed from the market. Also known as drotrecogin alfa (activated) or activated protein C, this medication is no longer available for use. Recommendations and guidelines (including the Canadian Association of Emergency Physicians [CAEP] sepsis guidelines1) require revision to reflect this important development.1 

The story of Xigris serves as a cautionary tale, which has both advanced and distracted the care of patients with severe sepsis/septic shock. Few emergency physicians may be aware of the history of this medication, the controversy surrounding it, and evidence leading to its use and subsequent termination as a treatment option.

18. Cochrane Review Says Topical NSAIDs a Better Choice for Elderly with OA 

Janis C. Kelly. Medscape Medical News. September 18, 2012 — Topical diclofenac is about as effective as oral diclofenac in knee and hand osteoarthritis (OA), is probably as effective as other oral NSAIDs, and might be a safer choice for elderly patients and others at risk for gastrointestinal adverse effects, according to an intervention review published online September 12 in the Cochrane Database of Systematic Reviews. 

Sheena Derry, PhD, and colleagues from the University of Oxford in the United Kingdom based their conclusions about topical NSAIDs on a review of randomized, double-blind studies with placebo or active comparators in which at least a single treatment was a topical NSAID used to treat chronic pain caused by OA, and in which treatment lasted at least 2 weeks. The analysis included data from 7688 participants in 34 studies, 23 of which compared a topical NSAID with placebo. 

"Topical NSAIDs were significantly more effective than placebo for reducing pain due to chronic musculoskeletal conditions," the authors conclude. "Direct comparison of topical NSAID with an oral NSAID did not show any difference in efficacy." Topical NSAIDs were associated with more local adverse events, such as mild rash, but with fewer gastrointestinal adverse events than oral NSAIDs. 

For topical diclofenac, the number needed to treat (NNT) for at least 50% pain relief vs placebo was 6.4 for diclofenac solution and 11 for diclofenac gel formulation. There were insufficient data to calculate NNTs for other individual topical NSAIDs. 

"The results presented here show clearly that high quality large studies demonstrate efficacy of topical NSAIDs in 12 week studies, with NNTs similar to those of oral NSAIDs," the authors write. 

Coauthor R. Andrew Moore, from the Pain Research Unit at Oxford University, told Medscape Medical News that in view of the low NNT for diclofenac solution, it would be reasonable for clinicians to view that formulation as good first-line therapy for hand or knee OA, especially in elderly patients. "It is what [the National Institute for Health and Clinical Excellence] in the UK suggest in their excellent OA guideline," Dr. Moore said. "This [is] nothing new for us, but then we have been looking at the evidence on topical NSAIDs for almost 20 years.... [And] what we said then is true now. Truer, perhaps." 

Experimental data suggest that creams are generally less effective than gels or sprays, according to the authors. "One of the features of topical NSAIDs is that formulation has the potential to play a big part in efficacy," Dr. Moore said. 

The authors write, "It is probable that topical NSAIDs exert their action both by local reduction of symptoms arising from periarticular structures, and by systemic delivery to intracapsular structures. Tissue levels of NSAIDs applied topically certainly reach levels high enough to inhibit cyclooxygenase-2. Plasma concentrations found after topical administration, however, are only a fraction (usually much less than 5%) of the levels found in plasma following oral administration. Topical application can potentially limit systemic adverse events by increasing local effects, and minimizing systemic concentrations of the drug. We know that upper gastrointestinal bleeding is low with chronic use of topical NSAIDs." 

Roy Altman, MD, professor emeritus, Division of Rheumatology, University of California, Los Angeles, reviewed the study for Medscape Medical News. "I think this Cochrane review was well done and carefully reported," Dr. Altman said. "The data are convincing. Their results are concordant with our results from the literature and consistent with our recommendations of the American College of Rheumatology guidelines published earlier this year. I suspect topical NSAIDs will eventually be approved for over-the-counter use, as they are in Europe. That will dramatically increase their use."

19. Suicides More Common than Traffic Deaths 

By Crystal Phend, Senior Staff Writer, MedPage Today, September 25, 2012 

Suicide has overtaken traffic accidents as the leading cause of injury deaths in the U.S., a national study found. The suicide rate rose 15% over the past decade, while unintentional motor vehicle crashes fell 25%, Ian R.H. Rockett, PhD, MPH, of the West Virginia University School of Public Health in Morgantown, and colleagues found. 

Deaths from poisoning and falls also rose substantially from 2000 through 2009, the group reported online in the American Journal of Public Health. 

"Comprehensive and sustained traffic safety measures have apparently substantially diminished the motor vehicle traffic mortality rate, and similar attention and resources are needed to reduce the burden of other injury," they wrote. Eliminating fatal injuries might raise the national life expectancy by 1 to 2 years, "but it would extend the mean length of life of those whose deaths were averted by a projected 3 decades," they added. 

The researchers analyzed data on cause of death from the CDC's National Center for Health Statistics for patterns and trends in fatal injury from 2000 through 2009. Overall, combined unintentional and intentional injury mortality rose 10% over this period from 53 to 56 per 100,000 population after adjustment for trends in age. The adjusted total injury death rate fell 78% in the youngest age group -- those 14 and under, while the 75 and older group had a 2.8-fold increase. Total injury death rates rose more among females and whites than among other groups. 

The five leading causes of injury deaths accounted for an increasing proportion, up from 77% to 82% over the study period. 

Shifts occurred within the list as well. Suicide took over from motor vehicle accidents as the leading cause of injury death in 2009, with an age-adjusted rate of 12 per 100,000 population in that year. Motor vehicle crashes remained in second place with an age-adjusted rate of 11 per 100,000. "Our finding that suicide now accounts for more deaths than do traffic crashes echoes similar findings for the European Union, Canada, and China," Rockett's group noted. 

Poisoning rose the most among the injury-related causes of death. The 128% increase from 2000 to 2009 bumped homicide out of third place in 2003. These deaths were largely accounted for by overdoses of prescription drugs, particularly opioid analgesics. 

Tackling fatal overdoses may take a multi-pronged approach, the investigators noted. "Several promising prevention and control strategies have recently been implemented, including Prescription Drug Monitoring Programs, the Food and Drug Administration's Opioid Drugs and Risk Evaluation and Mitigation Strategies, provider prescribing guidelines, and single provider-single pharmacist 'lock-in' programs," they wrote. 

Falls also surpassed homicide in 2004 to become the fourth most common cause of injury deaths at a rate of 7 per 100,000 in 2009, which reflected a 54% increase since 2000. The increase in fall-related deaths was greater with older age and disproportionately affected men and whites. Homicide ended up as the fifth leading cause of injury deaths, with an 8% decline to an age-adjusted rate of 5 per 100,000 in 2009. 

Limitations of the study were largely due to the quality of the information recorded on the death certificate, which could have been influenced by differential reporting stemming from "variable training, resources, philosophies, procedures, and practices of medical examiners and coroners," Rockett's group cautioned. Distinguishing intentional from unintentional injury is also a challenge, they noted.The study was supported in part by grants from the CDC and the National Institute on Alcohol Abuse and Alcoholism.

20. Kaiser study finds efficacy of DTaP vaccine is short-lived 

A Kaiser Permanente study found that the diphtheria and tetanus toxoids and acellular pertussis adsorbed, or DTaP, vaccine had a short efficacy span in preventing pertussis and that protection declined quickly after the fifth and final dose. Researchers said preventing future whooping cough outbreaks may require new vaccines or reformulating existing ones to provide longer immunity. The study was reported in the New England Journal of Medicine. 


21. Infecting the Electrocardiogram 

Fredrickson M, et al. Arch Intern Med. 2012 Oct 1:1. doi: 10.1001/archinternmed.2012.3740a. [Epub ahead of print] 

A 60-year-old man with no known medical history was admitted to our emergency department following an episode of syncope. The patient was at work when he suddenly developed tunnel vision and lightheadedness followed by loss of consciousness for 10 seconds. There was no chest pain, shortness of breath, or palpitations. His blood pressure was 118/37 mm Hg, with a heart rate of 38 beats/min. He was alert and oriented. Heart sounds were normal with an irregular rate, no murmurs or gallop, and symmetric pulses. An initial electrocardiogram (ECG) was obtained (Figure 1: http://archinte.jamanetwork.com/article.aspx?articleid=1368354).  

What are the significant findings and what is the differential diagnosis?

22. Readers Beware: 'Spinning' Study Results Happens at All Levels 

By Cole Petrochko, Associate Staff Writer, MedPage Today. September 11, 2012 

The positive "spin" that study abstracts and press releases put on research outcomes can distort -- and possibly misinform -- media coverage of those studies, researchers found. 

Spin in a study press release was significantly associated with spin in news reports on that study (P less than 0.001), which was then significantly associated with an overestimation of study benefits compared with media stories without spin (P=0.009), according to Isabelle Boutron, PhD, of the Institut National de la Santé et de la Recherche Médicale in Paris, and colleagues. 

In addition, spin -- defined as reporting that emphasized "the beneficial effects of the experimental (new) treatment" -- was nearly six times more likely to be found in a press release if the conclusion of the abstract also was "spun" (RR 5.6, 95% CI 2.8 to 11.1, P less than 0.001), Boutron and co-authors wrote online in PLoS Medicine. 

"'Spin' can distort the transposition of research into clinical practice and, when reproduced in the mass media, it can give patients unrealistic expectations about new treatments," the authors added. 

Boutron and colleagues studied the presence of spin in press releases and news coverage and whether the presence of spin leads to misrepresentation of study findings in those releases. The authors found 70 studies with associated press releases, as well as 41 news stories based on the press releases. 

Studies were evaluated for whether the researched treatment was beneficial to patients. A press release or news article was considered to misrepresent a study if the benefit of the treatment was overestimated or if adverse effects were underestimated. 

Just under half (49%) of the studies had statistically significant findings, while just over a third (34%) had no statistically significant primary outcomes. Still, 40% of the articles had some kind of spin in the abstract conclusion, including:
·         No acknowledgement of nonstatistically significant primary outcomes (20%)
·         Establishing P-values larger than 0.05 as equivalent (7%)
·         Inappropriate extrapolation (9%)
·         Focusing on significant results in subgroup analyses (6%), within-group comparisons (9%), and secondary outcomes (4%)
·         Inadequate claims of safety (6%) 

Additionally, 47% of the press releases and 51% of the news stories contained spin. 

Studies that were spun in news coverage were more likely to be published in a specialty journal rather than a general one (67% versus 35%, P=0.04), to have a small sample size versus a large one (68% versus 32%, P=0.02), and to be based on studies with spin in the abstract or press release versus no spin (100% versus 5% and 100% versus 13%, respectively, P less than 0.001 for both). 

News reports also were significantly more likely to overestimate study benefit when the study had a small versus large sample size (41% versus 5%, P less than 0.01) or if the news story contained spin on the study findings (43% versus 5%, P=0.009). 

Spin was significantly more likely to appear in studies with a small sample size versus a large sample size (63% versus 31%, P=0.008) and in studies with spin in the abstract conclusion versus articles without any (93% versus 17%, P less than 0.001). Similarly, risk of spin in the press release was significantly associated with spin in the abstract conclusion (RR 5.6, 95% CI 2.8 to 11, P less than 0.001). 

In a comparison of results based on press release data versus the study's full text, 79% of treatments were considered beneficial in press releases versus 54% in the full text, 3% were of neutral benefit versus 26%, and 18% were not beneficial versus 20%. 

Factors significantly associated with misinterpreted study outcomes included publication in a specialized versus general journal (45% versus 6%, P less than 0.001), small versus large sample size (46% versus 9%, P less than 0.001), and presence of spin in the press release versus no spin (48% versus 8%, P less than 0.001). Data in studies with nonstatistically significant versus significant primary outcomes also were misrepresented more often (42% versus 20%, P=0.05). 

The authors noted that spin, in conjunction with other biases in reporting, "may be responsible for an important gap between the public perception of the beneficial effect and the real effect of the treatment studied." 

They added that, although press releases are meant to summarize and contextualize findings rather than detail the complete study, use of spin in press releases can be problematic if it "modifies readers' interpretation of research findings." And they noted that the findings "raise the issue of the quality of the peer review process and highlight the importance of this process for disseminating accurate research results." 

Boutron and colleagues said their research was limited by their use of studies reported in English with releases housed in a single source and within a 4-month period, and that the single source did not reflect on all press releases or news reports. They also did not search for spin in the article bodies and recognized their analyses and interpretations were based on subjective measures. 

The authors declared no conflicts of interest.

23. U.S. Warning to Hospitals on Medicare Bill Abuses 

By Reed Abelson and Julie Creswell. New York Times September 24, 2012 

Saying there are “troubling indications” of abuse in the way hospitals use electronic records to bill forMedicare and Medicaid reimbursement, the Obama administration warned on Monday that it would not tolerate what it called attempts to “game the system” and vowed to vigorously prosecute doctors and hospitals implicated in fraud. 

The strongly worded letter, signed by the attorney general, Eric H. Holder Jr., and the secretary of health and human services, Kathleen Sebelius, said that “electronic health records have the potential to save money and save lives.” 

But the letter continued: “There are troubling indications that some providers are using this technology to game the system, possibly to obtain payments to which they are not entitled. False documentation of care is not just bad patient care; it’s illegal.” 

“Obviously, we are very concerned” that the adoption of electronic health records “could lead to coding inappropriately,” an administration official said. While aggressively looking for any providers who are committing fraud, the administration will also consider whether it needs to make changes in the way it pays for care. 

The letter, sent to five major hospital trade associations, cited possible abuses including “cloning” of medical records, where information about one patient is repeated in other records, to inflate reimbursement. 

“There are also reports that some hospitals may be using electronic health records to facilitate ‘upcoding’ of the intensity of care or severity of patients’ condition as a means to profit with no commensurate improvement in the quality of care,” the letter said. 

The letter was sent two days after a front-page article in The New York Times detailed the ways in which the greater use of electronic records by hospitals and doctors might be contributing to a rise in Medicare billing. Much of the higher billing is taking place in hospital emergency rooms, where hospitals are classifying many more patients as sicker and needing more care. 

Hospitals received $1 billion more in Medicare reimbursements in 2010 than they did five years earlier, at least in part by changing the billing codes they assign to patients in emergency rooms, according to an analysis by The Times of Medicare data from the American Hospital Directory. Regulators also say physicians have changed the way they bill for office visits similarly, increasing their payments by billions of dollars.

Regulators, including the Office of Inspector General for Health and Human Services, are concerned about the increase in billing for the most expensive evaluation services by hospitals, in the emergency room, and by doctors in their offices. Private insurers have also expressed concern about the higher level of billing. 

The Centers for Medicare and Medicaid Services is conducting audits to prevent improper billing. The agency is also starting more extensive medical reviews of billing practices that will identify those hospitals or doctors that are billing for much more expensive services than their peers, according to the letter. While not unprecedented, the letter is especially blunt. 

The issue of Medicare costs is a contentious one in the presidential campaign and has been a centerpiece of the Obama administration. As part of a push that began under the Bush administration, government officials are spending tens of billions of dollars to encourage hospitals and doctors to use electronic records as a way to reduce costs and improve care. 

“This letter underscores our resolve to ensure payment accuracy and to prevent and prosecute health care fraud,” the letter said. The letter reminded hospitals that a patient’s medical information “must be verified individually to ensure accuracy: it cannot be cut and pasted from a different record of the patient, which risks medical errors as well as overpayments.” 

The five hospital associations receiving the letter were the American Hospital Association, the Federation of American Hospitals, the Association of Academic Health Centers, the Association of American Medical Colleges and the National Association of Public Hospitals and Health Systems. The associations, in turn, will notify their member hospitals about the administration’s concerns. Many hospitals and doctors argue that the new systems allow them to more accurately record information about their patients, leading to higher payments for the services they provide. They say the paper records often did not reflect how sick the patients they were treating were and how much time hospitals and doctors were spending during a visit. 

Rich Umbdenstock, the chief executive of the American Hospital Association, which represents more than 5,000 member hospitals, responded to the administration’s letter, saying hospitals “take seriously their obligation to properly bill for the services they provide to Medicare and Medicaid beneficiaries.” 

“We agree that the alleged practices described in your letter, such as so-called ‘cloning’ of medical records and ‘upcoding’ of the intensity of care, should not be tolerated,” he wrote in a letter. The letter also called for Medicare to develop clear national guidelines for the billing of hospital emergency room and clinic visits. 

Some experts have criticized federal officials for not providing more guidance to the software companies developing the electronic records or to hospitals and doctors about what is and what is not allowed. Officials say they are considering whether they need to take additional steps to clarify the rules and educate hospitals and doctors. “Those are steps we could consider in the future,” said the administration official. The letter from Ms. Sebelius and Mr. Holder said, “As we phase in electronic health records, though, we ask for your help in ensuring these tools are not misused or abused.” 

The administration said it had undertaken record-high collections and prosecutions against fraud, contending that prosecutions in 2011 were 75 percent higher than in 2008. In a report last February about the administration’s efforts, officials said the federal government had received about $2.4 billion in fiscal 2011 from health care fraud settlements and judgments. 

24. Largest Study Ever Links Electronic Health Records with Improved Patient Outcome 

Zina Moukheiber, Forbes. October 3, 2012  

A study conducted at HMO giant Kaiser Permanente involving nearly 170,000 patients with diabetes found that use of electronic health records helped significantly reduce A1c levels (average blood glucose over the previous three months) and LDL cholesterol in patients with the highest levels, indicating better monitoring and treatment. Those with lower A1c and LDL values experienced incremental improvements. Since their target levels were under control, they underwent less testing, suggesting electronic health records could actually reduce overtesting.  

The study, which appears tomorrow in Annals of Internal Medicine, was conducted between 2004 and 2009 at 17 medical centers in Northern California. During that period, Kaiser Permanente was making the transition from a patchwork of health IT systems and paper charts to Epic Systems at a cost of $4 billion—the largest implementation of a commercial electronic health record. The National Institute of Diabetes and Digestive and Kidney Diseases funded the study.  

Patients who were tracked had been Kaiser members since 2003. “We wanted to determine whether an EHR had a positive or negative impact on diabetes patients,” says Marc Jaffe, an endocrinologist at Kaiser, and an author of the study. “It [use of EHRs] helps us target patients.”  

Jaffe and his colleagues, including lead author and research scientist Mary Reed, looked at blood tests taken at intervals recommended by the American Diabetes Association, and drug prescriptions. They excluded patients on insulin, because intake was more difficult to gauge, and the bulk of diabetes patients in the registry were on pills. Jaffe posits that the drop in A1c and LDL levels was not only due to a readjustment in dosage or a switch in medication, but also possibly to better compliance to existing medication in patients with the most elevated levels.  

At the very least, electronic health records didn’t harm patients. “Skeptics who say the effort and energy that go into implementing an EHR detract from care have clearly been disproved,” says Jaffe. Hopefully, those kinds of promising results can be replicated elsewhere.

1. IV Combos Work for Agitation in the ED 

By Todd Neale, Senior Staff Writer, MedPage Today. September 15, 2012 

For patients with acute agitation in the emergency department, adding either droperidol or olanzapine to midazolam reduces the time to sedation compared with midazolam alone, a randomized trial showed. 

The time to sedation was 10 minutes with midazolam alone (95% CI 4 to 25), 6 minutes with the droperidol combination (95% CI 3 to 10), and 5 minutes with the olanzapine combination (95% CI 3 to 10), according to David Taylor, MD, of Austin Health in Heidelberg, Australia, and colleagues. 

The differences between each of the antipsychotic combinations and midazolam alone were statistically significant, but the study was not designed to detect differences between the two groups receiving droperidol or olanzapine, the researchers reported online in Annals of Emergency Medicine. They noted, however, that "anecdotal evidence, current practice, and this study suggest their effects are similar." 

When patients come into the emergency department with acute agitation, parenteral benzodiazepines -- like midazolam -- and antipsychotics are often used when other strategies are not possible or don't work. Benzodiazepines and antipsychotics are sometimes used together, although there are insufficient data to support the use of such combinations. 

The current trial included 336 adult patients (median age 32 to 35) who required intravenous drug sedation for acute agitation in one of three large metropolitan emergency departments. They were randomized to one of three treatments:
·         An IV bolus of a saline solution representing placebo droperidol and placebo olanzapine
·         An IV bolus of droperidol 5 mg plus placebo olanzapine
·         An IV bolus of olanzapine 5 mg plus placebo droperidol 

In each group, the treatment was followed immediately by incremental IV midazolam boluses of 2.5 to 5 mg until sedation was achieved. Sedation was defined as a score of 2 or lower on a six-point sedation scale, indicating that the patients were mildly aroused, pacing, and willing to talk reasonably, were settled with minimal agitation, or were asleep. 

The time to sedation was significantly shorter in both of the antipsychotic groups, such that at any point patients in either the droperidol or olanzapine groups were more likely than those in the control group to be sedated. The hazard ratio for sedation was 1.61 (95% CI 1.23 to 2.11) for droperidol and 1.66 (95% CI 1.27 to 2.17) for olanzapine. 

In addition, patients in the two active treatment groups required less rescue therapy after sedation was initially achieved. 

Adverse events occurred in 15.7% of the control group, 10.7% of the droperidol group, and 8.3% of the olanzapine group. All were easily managed, according to the authors. Although the label for droperidol contains a boxed warning related to prolonged QT, patients receiving that drug had a corrected QT interval similar to that in the other groups. 

"Our findings do not support the Food and Drug Administration black box warning for droperidol ...," the researchers wrote. "However, firm conclusions cannot be made because the study was not powered to compare corrected QT intervals, not all patients had an ECG performed, and only single ECGs were performed." 

Taylor and colleagues acknowledged some limitations of the study, including possible selection bias because not all suitable patients were enrolled and possible observer bias in the use of the sedation scale.

 2. Clinical Policy: Critical Issues in the Prescribing of Opioids for Adult Patients in the ED 

Cantrill SV, et al. Ann Emerg Med. 2012;60:499-525. 

This clinical policy deals with critical issues in prescribing of opioids for adult patients treated in the emergency department (ED). This guideline is the result of the efforts of the American College of Emergency Physicians, in consultation with the Centers for Disease Control and Prevention, and the Food and Drug Administration. The critical questions addressed in this clinical policy are: (1) In the adult ED patient with noncancer pain for whom opioid prescriptions are considered, what is the utility of state prescription drug monitoring programs in identifying patients who are at high risk for opioid abuse? (2) In the adult ED patient with acute low back pain, are prescriptions for opioids more effective during the acute phase than other medications? (3) In the adult ED patient for whom opioid prescription is considered appropriate for treatment of new-onset acute pain, are short-acting schedule II opioids more effective than short-acting schedule III opioids? (4) In the adult ED patient with an acute exacerbation of noncancer chronic pain, do the benefits of prescribing opioids on discharge from the ED outweigh the potential harms? 


3. Small Strokes, TIA Can Be Disabling 

By Nancy Walsh, Staff Writer, MedPage Today. September 14, 2012 

A substantial 15% of patients who've had a transient ischemic attack (TIA) or minor stroke are disabled 3 months later, particularly if they had persistent symptoms and a high-risk phenotype seen on imaging, a Canadian prospective study found. 

The risk of disability was more than doubled in patients whose symptoms were ongoing during emergency department evaluation (OR 2.4, 95% CI 1.3 to 4.4, P=0.004), according to Shelagh B. Coutts, MD, and colleagues from the University of Calgary in Alberta. 

Similar high risks also were seen if CT or CT angiography revealed acute ischemic changes or more than 50% stenosis near the ischemic area (OR 2.4, 95% CI 1.4 to 4.0, P=0.001), the researchers reported online in Stroke: Journal of the American Heart Association. Risk assessment after minor stroke or TIA has traditionally focused on recurrence, not disability, yet studies have suggested that neurologic problems can worsen and standard evaluations may not identify certain deficits that can be disabling. Treatment for these patients also has been inadequate. 

"A common reason for patients to be excluded from thrombolysis is that [the events] are considered 'too mild'," the researchers noted. To explore the potential predictors of poor outcome after TIA or a minor stroke (less than 4 on the NIH Stroke Scale score), Coutts and colleagues analyzed data from a series of 499 patients referred to the Foothills Medical Center in Calgary who were previously not disabled. More than half were men, and median age was 69.  

A total of 61% had ongoing symptoms when seen in the emergency department, and the median time until CT was performed following symptom onset was about 5 hours. MRI also was successfully done in 82% of patients. 

Disability was defined as having a score of 2 or higher on the modified Rankin scale. Most of the 74 patients who had a disabled outcome had a modified Rankin score of 2 (42). Baseline characteristics associated with disability at 3 months included age older than 60, diabetes, higher baseline NIH Stroke Scale score (median baseline score was 1), high-risk CT findings, and positive findings on MR diffusion-weighted imaging. 

Aside from ongoing symptoms and high-risk CT findings, multivariate analysis found significant predictive ability for the following:
·         Diabetes, OR 2.3 (95% CI 1.2 to 4.3, P=0.009)
·         Female sex, OR 1.8 (95% CI 1.1 to 3, P=0.025)
·         Baseline NIH Stroke Scale score-per point, OR 1.49 (95% CI 1.2 to 1.9, P less than 0.001) 

The researchers also conducted an exploratory analysis in which they excluded patients who had recurrent cerebrovascular events and found similar results for high-risk CT findings (OR 2.02, 95% CI 1.1 to 3.6, P=0.017) and persistent symptoms in the emergency department (OR 2.2, 95% CI 1.2 to 4.3, P=0.017). 

Among the 74 patients who were disabled at 3 months, only 26% had had a recurrent event. But among those with a second event, 53% were disabled (RR 4.4, 95% CI 3.0 to 6.6, P less than 0.0001). Therefore, while most patients who became disabled had only the primary event, those who did have second events were at very high risk for adverse outcomes. "Recurrent events are therefore a very important surrogate for disability but numerically not the major factor in predicting a disabled outcome," Coutts and colleagues observed. These findings about the outcomes following minor strokes or TIAs were "surprising," they noted. 

"Our study is novel in that it emphasizes the need to examine disability even in minor strokes and brings together careful clinical assessments and imaging data to emphasize this point," they stated. 

Future research should explore the possible reasons for why certain individuals become disabled even after an apparently small stroke or TIA, and should examine more refined ways of measuring minor disabilities than were used in this study. The researchers concluded that patients with TIAs or minor strokes that have high-risk features should be considered for thrombolytic therapy and other treatments. "Furthermore, it is clear that the issue of disability after minor stroke requires much more careful consideration as the relevant outcome rather than simply recurrent stroke," they wrote.

4. Lactate Level Correlates with Prognosis in Patients with Suspected Infection 

This large study identified a nearly linear relationship between lactate level and mortality. 

To analyze the relationship between blood lactate levels and mortality in patients with suspected infection, researchers reviewed charts from 2596 patients who were admitted from the emergency department (ED) with suspected infection (inferred from administration of antibiotics in the ED) and who had blood lactate levels measured in the ED. 

Overall in-hospital mortality was 14.4%, and the median initial lactate level was 2.1 mmol/L. The initial lactate level was over 4 mmol/L in 17.6% of patients. Mortality rose continuously across a continuum of incremental lactate elevations, ranging from 6% in patients with lactate levels less than 1.0 mmol/L to 39% in patients with levels of 19 to 20 mmol/L. 

Comment: We can draw two important conclusions from this study. First, patients with suspected infection who have lactate levels less than 4 mmol/L still are at risk of dying, so physicians should not base their evaluation of illness severity and patient risk solely on lactate level. Second, mortality risk increases with increasing lactate level, making resuscitation of patients with higher levels a priority.

5. New Strep Throat Guidelines Tackle Antibiotic Resistance 

Most sore throats are actually caused by viruses 

MONDAY, Sept. 10 (HealthDay News) -- Doctors need to accurately diagnose and treat strep throat in order to avoid inappropriate use of antibiotics that can lead to drug-resistant bacteria, according to updated guidelines from the Infectious Diseases Society of America. 

People often say they have strep throat. Most sore throats are caused by a virus, however, not by Streptococcus bacteria, and should not be treated with antibiotics, which are ineffective against viruses, noted an IDSA news release. 

Research shows that up to 15 million people in the United States go to the doctor for a sore throat every year. As many as 70 percent of patients receive antibiotics for a sore throat, but only 20 percent of those patients have strep throat, according to the IDSA. 

The guidelines also advised that when a strep infection is confirmed by testing, it should be treated with penicillin or amoxicillin -- if the patient does not have an allergy -- and not with an antibiotic such as cephalosporin. "We recommend penicillin or amoxicillin for treating strep because they are very effective and safe in those without penicillin allergy," lead author Dr. Stanford Shulman, chief of infectious diseases at the Ann & Robert H. Lurie Children's Hospital of Chicago, said in the news release. Other antibiotics more likely to lead to drug resistance also are more expensive, Shulman added. 

Children who have recurrent strep throat should not have their tonsils removed solely to reduce the frequency of throat infections, according to the guidelines. Patients with a sore throat do not need to be tested for strep throat if they have a cough, runny nose, hoarseness or mouth sores. These are strong signs of a viral infection. 

The guidelines, published online Sept. 10 and in the October issue of the journal Clinical Infectious Diseases, also outline what tests to conduct if strep throat is suspected and how to treat the condition.

6. Sedation-assisted orthopedic reduction in emergency medicine: The safety and success of a one physician/one nurse model.  

Vinson DR, Hoehn C. West J Emerg Med. 2012 September [Epub ahead of print]  

Introduction: Much of the emergency medical research on sedation-assisted orthopedic reductions has been undertaken with two physicians—one dedicated to the sedation and one to the procedure. Clinical practice in community emergency departments (EDs), however, often involves only one physician, who both performs the procedure and simultaneously oversees the crendentialed registered nurse who administers the sedation medication and monitors the patient. Although the dual-physician model is advocated by some, evidence in support of its superiority is lacking. 

Methods: In this electronic health records review we describe sedation-assisted closed reductions of major joints and forearm fractures in three suburban community EDs. The type of procedure and sedation medication, need for specialty assistance, success rates, and intervention-requiring adverse events are reported. 

Results: During the 18-month study period, procedural sedation was performed 457 times on 442 patients undergoing closed reduction for shoulder dislocations (n=111), elbow dislocations (n=29), hip dislocations (n=101), and forearm fractures (n=201). In the vast majority of this cohort (98.4% [435/442]), a single emergency physician simultaneously managed both the procedural sedation and the initial orthopedic reduction without the assistance of a second physician. The reduction was successful or satisfactory in 96.6% (425/435; 95% confidence interval [CI], 95.8-98.8%) of these cases, with a low incidence of intervention-requiring adverse events (2.8% [12/435]; 95% CI, 1.5-4.8%).

Conclusion: Sedation-assisted closed reduction of major joint dislocations and forearm fractures can be performed effectively and safely in the ED using a one physician/one nurse model. A policy that requires a separate physician (or nurse anesthetist) to administer medications for all sedation-assisted ED procedures appears unwarranted. Further research is needed to determine which specific clinical scenarios might benefit from a dual-physician approach.  


7. Validation of a Clinical Prediction Model for Early Admission to the Intensive Care Unit of Patients with Pneumonia 

Labarère J, et al. Acad Emerg Med. 2012;19;993-1003.  

Objectives:  The Risk of Early Admission to the Intensive Care Unit (REA-ICU) index is a clinical prediction model that was derived based on 4,593 patients with community-acquired pneumonia (CAP) for predicting early admission to the intensive care unit (ICU; i.e., within 3 days following emergency department [ED] presentation). This study aimed to validate the REA-ICU index in an independent sample. 

Methods:  The authors retrospectively stratified 850 CAP patients enrolled in a multicenter prospective randomized trial conducted in Switzerland, using the REA-ICU index, alternate clinical prediction models of severe pneumonia (SMART-COP, CURXO-80, and the 2007 IDSA/ATS minor severity criteria), and pneumonia severity assessment tools (the Pneumonia Severity Index [PSI] and CURB-65). 

Results:  The rate of early ICU admission did not differ between the validation and derivation samples within each risk class of the REA-ICU index, ranging from 1.1% to 1.8% in risk class I to 27.1% to 27.6% in risk class IV. The areas under the receiver operating characteristic (ROC) curve were 0.76 (95% confidence interval [CI] = 0.70 to 0.83) and 0.80 (95% CI = 0.77 to 0.83) in the validation and derivation samples, respectively. In the validation sample, the REA-ICU index performed better than the pneumonia severity assessment tools, but failed to demonstrate an accuracy advantage over alternate prediction models in predicting ICU admission. 

Conclusions:  The REA-ICU index reliably stratifies CAP patients into four categories of increased risk for early ICU admission within 3 days following ED presentation. Further research is warranted to determine whether inflammatory biomarkers may improve the performance of this clinical prediction model.

9. Team Effort Cuts In-Hospital Blood Infections 

By Joyce Frieden, News Editor, MedPage Today. September 10, 2012 

A combination of best practices, improved safety culture, and a bigger focus on teamwork cut central-line-associated bloodstream infections (CLABSIs) in hospitals by 40%, the Agency for Healthcare Research and Quality (AHRQ) reported. 

In preliminary results from a project involving hospital teams at more than 1,100 intensive care units over a 4-year period, the rate of CLABSIs was reduced from 1.903 infections per 1,000 central line days to 1.137 infections per 1,000 line days, the agency said. Overall, more than 2,000 CLABSIs were prevented, more than 500 lives were saved, and more than $34 million in healthcare costs were avoided, according to AHRQ. 

"No patient should ever become sicker as result of care he or she receives," AHRQ Director Carolyn Clancy, MD, said at a press conference Monday. "Until recently, these infections were thought to be an [unavoidable] consequence of care. But they can be prevented." 

The program, known as CUSP, centered around four basic concepts, explained Michael Tooke, MD, chief medical officer at Memorial Hospital in Easton, Md., one of the participating facilities. He listed the "4 E's" of the program:
·         Engagement -- getting the entire staff involved
·         Education -- teaching the staff about best practices for preventing CLABSIs
·         Execution -- carrying out the program
·         Evaluation -- keeping track of the results and feeding them back to the staff 

"We also had another 'E' -- enthusiasm," Tooke said. "We acknowledged every victory – one month without infection, a whole year – and had a party for every one." 

Components of the program include a procedure checklist, educating staff members on best practices, and trying to change the culture so that infections are considered unacceptable, said Peter Pronovost, MD, PhD, senior vice-president for safety and quality at Johns Hopkins Medicine and one of the developers of the CUSP system. Pronovost explained that he was inspired to tackle the CLABSI problem after a pediatric patient at the hospital died from what he described as "a cascade of errors starting with a central line bloodstream infection." 

"We set out to change this – it worked," Pronovost said. "We virtually eliminated these infections at Hopkins." Since the program started, many hospitals now "have infection rates previously believed impossible." 

Theresa Hickman, RN, of Peterson Regional Medical Center in Kerrville, Texas, said one of the changes the program wrought at her hospital was making sure physicians washed their hands before inserting a line. "We made it so that if the nurse did not see a physician washing hands prior to the procedure, it was considered that the physician didn't wash his hands," she said.  

Hickman noted that her 125-bed rural hospital has not had a CLABSI in its entire facility for 31 months. "Before this, having CLABSIs was part of the price of doing business. Now we know that's not true, and we can keep patients from dying," she said. 

The key to the program is the toolkit provided by AHRQ, which is available to any hospital that wants it and can be adapted to any hospital's particular situation, Tooke said. "It's full of different things that apply to different situations." 

The speakers agreed that success in a program such as this one is very empowering. "Once [a facility] gets started, and they have those zeroes [for zero infections], they become extremely protective of those zeros," said Hickman. "Not too long ago, one nurse called and said, 'I think we have a CLABSI' and she was distraught. It turned out they did not. They become very proud of that." 


9. Public Health Concerns 

A. Commentary: Death on Our Nation's Roadways: Not Just for Cars 

Thoma T. Ann Emerg Med. 2012;60:496-498.  

“Motor vehicle accident.” The emergency medicine residents in our program run for cover when they hear the unsuspecting off-service intern use that term while presenting a case to me. They know that it is the trigger for a long diatribe explaining that motor vehicle crashes are not “accidents.” The unsuspecting physician hears a well-rehearsed lecture explaining that the whole premise of injury prevention is to assume that trauma is a preventable disease. I frequently use the example of a 17-year-old male adolescent driving on a country road at night at a high rate of speed, under the influence of alcohol and without a seat belt, who loses control and is involved in a rollover motor vehicle crash. Consequently, he is ejected and dies. I then ask the physician to explain to me how this young man experienced an unavoidable act of God or how it was just “an accident.” Close evaluation of this crash with the application of Haddon's matrix (a system for evaluating human, vehicle, and environmental factors contrasted to pre-event, event, and postevent phases) yields multiple points of intervention for prevention of this outcome. This young man was the victim of a “crash” or “collision” and the event was wholly avoidable. 

I firmly believe this tenet, but as emergency physicians we are well aware that in avoidable crashes there are often innocent victims. Take, for example, the unsuspecting mother with her children who is driving down the highway in a minivan and falls prey to a distracted driver who crosses the midline. Because of the nature of modern transportation, there are inherent risks. Today we are a much more mobile society compared with when I was a child. There are many more vehicles on the road, and we travel more miles each year. Each vehicle traveling down the road carries with it a large amount of kinetic energy by virtue of its motion, and even the smallest mistakes can result in high-kinetic-energy crashes and injuries. Therein lies the concern.

B. The Bullet's Yaw: Reflections on violence, healing and an unforgettable stranger  

By Dustin W. Ballard, MD, MBE  

Jeffrey Mains was in shock. 

During a vengeful rampage, a deranged former security guard had fired a hollow point bullet into Mains’ truck. The bullet’s path through steel slowed its velocity, causing it to tumble sideways when it collided with Mains, a phenomenon that ballistics experts call the “bullet’s yaw.” The bullet’s impact and ensuing yaw were over in a blink, but the effects were profound. Mains’ bowel was pierced and leaking, his liver lacerated and one diaphragm ruptured. When the ambulance arrived, Jeffrey Mains was nearly unconscious; he was bleeding internally and desperately needed surgery. He was rushed, lights blazing and sirens calling, to the UC Davis Medical Center. This is where, several weeks and many complications later, he became my patient.  

During my three-year residency in emergency medicine I treated thousands of patients—strangers such as Jeffrey Mains. Most passed through my life swiftly and their illnesses left but a wisp in my memory. A handful of patients, however, marked me forever. The Bullet’s Yaw is the story of one of these unforgettable strangers and what he taught me about life, violence and healing.

11. Interventions to Improve Adherence to Self-administered Medications for Chronic Diseases in the United States: A Systematic Review  

Viswanathan M, et al. Ann Intern Med. 11 September 2012 [Epub ahead of print] 

Background: Suboptimum medication adherence is common in the United States and leads to serious negative health consequences but may respond to intervention. 

Purpose: To assess the comparative effectiveness of patient, provider, systems, and policy interventions that aim to improve medication adherence for chronic health conditions in the United States. 

Data Sources: Eligible peer-reviewed publications from MEDLINE and the Cochrane Library indexed through 4 June 2012 and additional studies from reference lists and technical experts. 

Study Selection: Randomized, controlled trials of patient, provider, or systems interventions to improve adherence to long-term medications and nonrandomized studies of policy interventions to improve medication adherence. 

Data Extraction: Two investigators independently selected, extracted data from, and rated the risk of bias of relevant studies. 

Data Synthesis: The evidence was synthesized separately for each clinical condition; within each condition, the type of intervention was synthesized. Two reviewers graded the strength of evidence by using established criteria. From 4124 eligible abstracts, 62 trials of patient-, provider-, or systems-level interventions evaluated 18 types of interventions; another 4 observational studies and 1 trial of policy interventions evaluated the effect of reduced medication copayments or improved prescription drug coverage. Clinical conditions amenable to multiple approaches to improving adherence include hypertension, heart failure, depression, and asthma. Interventions that improve adherence across multiple clinical conditions include policy interventions to reduce copayments or improve prescription drug coverage, systems interventions to offer case management, and patient-level educational interventions with behavioral support. 

Limitations: Studies were limited to adults with chronic conditions (excluding HIV, AIDS, severe mental illness, and substance abuse) in the United States. Clinical and methodological heterogeneity hindered quantitative data pooling. 

Conclusion: Reduced out-of-pocket expenses, case management, and patient education with behavioral support all improved medication adherence for more than 1 condition. Evidence is limited on whether these approaches are broadly applicable or affect long-term medication adherence and health outcomes. 


12. Needle Move Proposed for Tension Pneumothorax 

Damian McNamara. Medscape Medical News. September 18, 2012 — With trauma patients, it is traditional to decompress tension pneumothorax by quickly inserting a needle at the second intercostal space (ICS) in the midclavicular line. However, using computed tomography imaging, Kenji Inaba, MD, from the Department of Surgery, Division of Trauma and Surgical Critical Care, University of Southern California, Los Angeles, and colleagues confirmed that a second site features significantly less chest wall thickness, which could mean more patients would benefit from the procedure. The researchers published the results of their retrospective study in the September issue of the Archives of Surgery. 

The chest wall at the fifth ICS in the anterior axillary line is significantly thinner at than the second ICS in the midclavicular line, thus increasing the likelihood a decompression needle will traverse it completely and enter the chest cavity. Computed tomography images from 120 trauma patients revealed a 12.9-mm shorter mean difference (95% confidence interval [CI], 11.0 - 14.8 mm; P less than .001) in chest wall thickness on the right side between the second ICS in the midclavicular line vs the fifth ICS on the anterior axillary line. On the left side of the patients, researchers found a similar, significant 13.4-mm shorter difference (95% CI, 11.4 - 15.3 mm; P less than .001). 

Standard 5-cm decompression needles were too short to reach the chest cavity through the second ICS/midclavicular line for 42.5% of patients and were too short for 16.7% of patients treated through the fifth ICS/anterior axillary line. 

Interestingly, sex and body mass index made a difference. Women had greater chest wall thickness at all sites compared with men. Therefore, women in particular could benefit from nontraditional needle placement and/or use of longer needles, the authors suggest. 

In addition, the investigators grouped patients by body mass index and found that chest wall thickness increased stepwise with each higher body mass index quartile. They proposed that the increasing proportion of overweight or obese patients also supports a switch to the alternative needle insertion site. 

Mean patient age was 41 years (range, 16 - 97 years), and 81.5% were men. Mean body mass index was 27.9 kg/m2 (range, 15.4 - 60.7 kg/m2), and mean injury severity score was 15.5. 

This clinical study included 120 patients randomly selected from a group of 680 trauma patients aged 16 years and older who were treated at the Los Angeles County University of Southern California Medical Center between January 2009 and January 2010. The findings confirm previous research from the same institution comparing the 2 insertion sites in 20 cadavers. 

The authors of the current study found that 100% of 40 needles inserted through the fifth ICS entered the chest cavity compared with 57.5% of 40 needles placed through the second ICS. 

In an accompanying editorial, Martin A. Schreiber, MD, from the Department of Surgery at Oregon Health & Science University in Portland, described the study as being very well done. However, he writes, "These types of studies make one ask: How could we have done it so wrong for so long?" He also questioned the need to perform the clinical study, given the previous cadaver findings. 

Dr. Schreiber outlined several shortcomings. For example, because no patient actually underwent needle thoracostomy, a clinical correlation could not be made between chest wall thickness and procedure success rate. "They also have not addressed the potential complications of using a longer needle or the devastating complication of cardiac injury if the fifth ICS at the [anterior axillary line] is used." In addition, "angiocatheters kink easily in transport and they can be displaced." 

The authors have disclosed no relevant financial relationships.

13. NIPPV for CHF Works, ACLS Algorithms Do Not  

by David Newman, MD on September 26, 2012. Emergency Physicians Monthly 

A. Noninvasive ventilation 

Q: Does noninvasive positive pressure ventilation for CHF save lives? 

 a: Yes!

by Ashley E. Shreves, MD 

NNT=8
For every eight CHF patients you treat with NIPPV, one death is prevented

NNH=18
Side effects were minor, and the most common was gastric distension, then skin damage (20) and mask discomfort (30) 

Take Home Message: NIPPV for CHF appears to save lives, though the data only includes roughly 1000 subjects from both ICUs and EDs. 

B. The ACLS Algorithms 

Q: Do intravenous drugs, as recommended by ACLS algorithms, improve survival? 

a: Excellent studies say NO 

by David H. Newman, MD

NNT: For neurologically intact survival, there is NO BENEFIT. 

NNH: No medical harms were identified 

Take Home Message: Using the ACLS-recommended drug algorithm does not improve survival from cardiac arrest, though it does lead to more ICU admissions. 


14. Prehospital Point-of-Care Measurement of Troponin I Is Feasible 

Troponin I results did not differ when testing was performed in a moving ambulance or in the ED. 

Venturini JM et al. Prehosp Emerg Care 2012 Sep 6 

Background. Swift assessment of patients presenting with chest pain results in faster treatment and improved outcomes. Allowing ambulance crews to use point-of-care (POC) devices to measure cardiac troponin I levels during transport of patients to the emergency department (ED) may result in earlier diagnosis of acute myocardial infarction, particularly in those patients without ST-segment elevation. The ability of POC devices to measure cardiac troponin I levels reliably in a moving ambulance has not previously been tested.  

Objective. This study was conducted to determine whether POC devices operated in a moving ambulance reliably duplicate the measurement of cardiac troponin I levels obtained by POC devices in the ED.  

Methods. Blood samples were obtained in the ED and the hospital from patients reporting chest pain or other cardiac complaints. Troponin I assays were then performed in a moving ambulance using two POC devices. The POC devices were placed on flat surfaces in the rear of the ambulance. The ambulance driver was instructed to keep the ambulance moving in traffic while each assay was completed. A variety of routes were taken. Each set of two assays was completed entirely during a single simulated run. The results of the two assays performed in the moving ambulance were then compared with the results of the control assay, which was performed simultaneously in the ED on the same sample.  

Results. Forty-two whole-blood samples underwent troponin I assays in a moving ambulance. Thirteen (30.9%) assays were positive. One (2.4%) was excluded because of cartridge error. Two (4.8%) were excluded because of interfering substance. No significant difference in whole-blood troponin results was found between the assays performed in the moving ambulance and those performed in the ED (intraclass correlation coefficient 0.997; 95% confidence interval 0.994 to 0.998; p less than 0.005).  

Conclusions. When used in a moving ambulance, the POC device provided results of cardiac troponin I assays that were highly correlated to the results when the device was used in the ED. The feasibility, practicality, and clinical utility of prehospital use of POC devices must still be assessed.

16. Physiologic Monitoring Practices during Pediatric Procedural Sedation: A Report from the Pediatric Sedation Research Consortium 

Langhan ML, et al. Arch Pediatr Adolesc Med. Published online September 10, 2012. doi:10.1001/archpediatrics.2012.1023 

Objectives  To describe the frequency of different physiologic monitoring modalities and combinations of modalities used during pediatric procedural sedation; to describe how physiologic monitoring varies among different classes of patients, health care providers (ie, ranging from anesthesiologists to emergency medicine physicians to nurse practitioners), procedures, and sedative medications employed; and to determine the proportion of sedations meeting published guidelines for physiologic monitoring. 

Design  This was a prospective, observational study from September 1, 2007, through March 31, 2011. 

Setting  Data were collected in areas outside of the operating room, such as intensive care units, radiology, emergency departments, and clinics. 

Participants  Thirty-seven institutions comprise the Pediatric Sedation Research Consortium that prospectively collects data on procedural sedation/anesthesia performed outside of the operating room in all children up to age 21 years. 

Main Outcome Measures  Data including demographics, procedure performed, provider level, adverse events, medications, and physiologic monitors used are entered into a web-based system. 

Results  Data from 114 855 subjects were collected and analyzed. The frequency of use of each physiologic monitoring modality by health care provider type, medication used, and procedure performed varied significantly. The largest difference in frequency of monitoring use was seen between providers using electrocardiography (13%-95%); the smallest overall differences were seen in monitoring use based on the American Society of Anesthesiologists classifications (1%-10%). Guidelines published by the American Academy of Pediatrics, the American College of Emergency Physicians, and the American Society of Anesthesiologists for nonanesthesiologists were adhered to for 52% of subjects.

Conclusions  A large degree of variability exists in the use of physiologic monitoring modalities for pediatric procedural sedation. Differences in monitoring are evident between sedation providers, medications, procedures, and patient types. 

17. 'Gut Feelings' Matter in Diagnosis of Kids' Infections 

By Nancy Walsh, Staff Writer, MedPage Today. September 25, 2012.  

Physicians should pay attention to their "gut feeling" that something may be seriously wrong when assessing a child with an infectious disease -- even if the clinical appearance is reassuring -- an observational study suggested. 

Among 3,369 children whose primary care evaluation did not suggest a serious illness, six (0.2%) ultimately were admitted to the hospital with a severe infection, according to Ann Van den Bruel, MD, PhD, of the Radcliffe Observatory Quarter in Oxford, England, and colleagues. 

The clinician's gut feeling that the child was seriously ill considerably increased the chance that a severe infection was present, with a likelihood ratio of 25.5 (95% CI 7.9 to 82), and heeding the feeling might have prevented two cases from being overlooked (33%, 95% CI 0.95 to 1.75), the researchers reported online in BMJ. 

Considerable research has focused on developing tools for clinical prediction in acutely ill children, including symptoms, vital signs, and laboratory tests, but primary care physicians often see children before the full clinical picture has developed -- and sometimes report relying on intuition that a potentially serious problem exists even though they're unsure why. Moreover, a systematic review recently determined that such a gut feeling had considerable diagnostic significance. 

To clarify the usefulness of physicians' intuitive feelings as an addition to clinical impressions, Van den Bruel and colleagues recruited 3,890 acutely ill children presenting to primary care in Flanders, Belgium. 

For each child, the researchers reviewed the clinical features of the illness, including the physician's overall clinical impression of whether the illness was serious based on the physical examination, history, and observation. They also asked treating physicians for their gut feeling as to whether they suspected the illness was serious based on the appearance of the child or the attitude and behavior of the parent. Serious infections included pneumonia, sepsis, meningitis, pyelonephritis, cellulitis, osteomyelitis, and bacterial gastroenteritis requiring at least 1 day of hospitalization. 

A total of 21 children were hospitalized, with most ultimately being diagnosed with pneumonia or pyelonephritis. Among the children for whom the clinical impression was that the illness was nonserious, the two cases that weren't missed were accompanied by 44 "false alarms," giving a sensitivity of 33.3% and a specificity of 98.7% for the physicians' gut feelings. 

The researchers then looked at the clinical features that most often led to gut feelings that ran counter to the evidence, and found the strongest association for the child having a history of convulsions (OR 80.5, 95% CI 6.2 to 1,051). 

Parental impression that the illness was different from others also was very important (OR 26.93, 95% CI 9.02 to 80.41). 

Other features that led to physicians' gut feelings of serious illness, although less so than convulsions and parental concern, included:
·         Drowsiness, OR 3.49 (95% CI 1.04 to 11.75)
·         Changes in pattern of breathing, OR 4.88 (95% CI 1.38 to 17.26)
·         Weight loss, OR 16.83 (95% CI 3.29 to 85.96)
·         Urinary symptoms, OR 11.64 (95% CI 3.19 to 42.45) 

Temperature was not a significant factor, contrary to the expectations of the researchers. They noted that fever may have contributed to parental impressions of serious illness, however. 

"Nevertheless, it is important that primary care clinicians recognize the diagnostic value of fever in their clinical assessment -- for every 20 children with a temperature of 40° C [104° F) or more in a primary setting, one will have a serious infection," they cautioned. 

The presence of diarrhea also was not associated with gut feelings, which also concerned the researchers, who noted that diarrhea in a young child is not necessarily benign, because it can lead to dehydration and also could be an early symptom of sepsis. 

Among the 21 children who were hospitalized, nine were not admitted initially -- yet in four of those nine, the physician reported having a gut feeling that something was seriously wrong with the child. 

The researchers also considered the treating clinicians' years of experience, and found that the likelihood of their having gut feelings different from their clinical impression decreased by 5% each year. "This is presumably because the holistic clinical features that trigger gut feeling are gradually assimilated into clinical assessment," Van den Bruel and colleagues observed. 

They advised that medical training should emphasize the potential value of gut feelings, and suggested that any such feelings should warrant a "full and careful" examination, consulting with other more experienced clinicians or referral, and explanations to the parent of their need to observe the child diligently. 

"The observed association between gut feeling and clinical markers of serious infection means that by reflecting on the genesis of their gut feeling, clinicians should be able to hone their clinical skills," they concluded. 

The study was limited by its inclusion of only children in primary care, and a lack of power to analyze the specific details of clinicians' gut feelings. 

The study was supported by the Research Foundation-Flanders, Eurogenerics, and the National Institute for Health Research. The authors reported no financial conflicts.

18. Utility of Emergency Cranial Computed Tomography in Patients without Trauma 

Narayanan V, et al. Acad Emerg Med. 2012;19:E1055-E1060.  

Objectives:  The objectives of this study were to determine, in patients admitted to the hospital from the emergency department (ED) without evidence of trauma, 1) the prevalence of clinically important abnormalities on cranial computed tomography (CCT) and 2) the frequency of emergent therapeutic interventions required because of these abnormalities. 

Methods:  The authors retrospectively reviewed the records of all patients from 2007 between the ages of 18 and 89 years who had CCT as part of their ED evaluations prior to hospitalization. Patients with any indication of trauma were excluded, as were those who had a lumbar puncture (LP). Chief complaint, results of the ED neurologic examination, tomogram findings, and whether patients had emergent interventions were recorded. Patients presenting with altered mental status (AMS) were analyzed separately. 

Results:  Of the 766 patients meeting inclusion criteria, 83 (11%) had focal neurologic findings, and 61 (8%) had clinically important abnormalities on computed tomography. Emergent interventions occurred in only 12 (1.6%), 11 (92%) of whom had focal neurologic findings. In the subgroup of 287 patients with AMS as their presenting problem, 14 (4.9%) had focal findings, six (2%) had clinically important abnormalities on tomography, and only two (0.7%) required emergent interventions, both of whom had focal findings. Patients presenting with AMS were less likely to have positive findings on tomography (odds ratio [OR] = 0.16, 95% confidence interval [CI] = 0.07 to 0.39). Patients presenting with motor weakness or speech abnormalities, or who were unresponsive, were more likely to have positive findings on tomography (OR = 4.7, 95% CI = 2.6 to 8.6; OR = 4.4, 95% CI = 1.5 to 2.7; and OR = 3.3, 95% CI = 1.6 to 7.1, respectively). 

Conclusions:  Of patients without evidence of trauma who receive CCT in the ED, the prevalence of focal neurologic findings and clinically important abnormalities on tomography is low, the need for emergent intervention is very low, and the large majority of patients requiring emergent intervention have focal findings. The yield of CCT was lower for patients presenting with AMS, and higher for patients presenting with motor weakness or speech abnormalities, and for those who were unresponsive. 

19. NSAIDs May Hike Long-Term CV Risk Post-MI 

By Chris Kaiser, Cardiology Editor, MedPage Today. September 11, 2012.  

The use of nonsteroidal anti-inflammatory drugs (NSAIDs) may confer a long-term risk of adverse cardiovascular events, a Danish population study found. 

Of the nearly 100,000 patients with first-time myocardial infarction (MI) included in the analysis, those taking NSAIDs had a "persistent" increased risk of all-cause death at 1 year (HR 1.59, 95% CI 1.49 to 1.69) and at 5 years (HR 1.63, 95% CI 1.52 to 1.74), according to Anne-Marie Olsen, MD, a research fellow at Copenhagen University Hospital Gentofte in Hellerup, Denmark, and colleagues. 

In addition, those taking these anti-inflammatory drugs had a 41% increased risk of a second MI and a 30% increased risk of coronary death during the 5-year follow-up, they reported online in Circulation: Journal of the American Heart Association. 

While epidemiological studies such as this cannot establish causality, they said their results are further evidence of an association between COX-2 inhibitors and severe adverse cardiovascular events. "We advise long-term caution in using NSAIDs for patients after MI," they concluded. They also suggested that the availability of over-the-counter nonselective NSAIDS such as diclofenac and ibuprofen "should be reconsidered." 

Although taking any NSAID increased the risk compared with taking none, use of diclofenac was associated with the highest risk, they pointed out. Other NSAIDs evaluated in this study were rofecoxib (Vioxx), celecoxib (Celebrex), naproxen (Aleve, among other brand names), and others. At the time of the study, only ibuprofen (200 mg) was available over the counter in Denmark. 

Despite a focused update in 2007 from the American Heart Association cautioning against the use of NSAIDs for those with cardiovascular disease, many still receive these drugs, although for shorter periods (Circulation 2007; 115: 1634-1642), Olsen and colleagues wrote. 

Because the long-term effects of NSAIDs among those with a first MI were unclear, researchers analyzed data from 99,187 patients in the Danish National Patient Registry from 1997 to 2009. There were more men (64%) than women in the study, the mean age was 69, and 44% had filled at least one prescription of NSAIDs. 

Researchers found that the overall adverse risks associated with NSAIDs "remained virtually unchanged throughout all 5 years after discharge from hospital after the first MI." This is in contrast to the typical risk of cardiovascular mortality and morbidity following an MI, which declines as time passes, Olsen and colleagues noted. 

However, rofecoxib and diclofenac conferred a greater risk of death and the composite of recurrent MI and coronary death over time compared with other NSAIDs, especially naproxen, which had the lowest risk. Although it might be preferable to prescribe naproxen, researchers noted that the drug was associated with a higher risk of gastrointestinal bleeding than rofecoxib. They also found that those not taking anti-inflammatory drugs had a decreased risk of adverse events over the 5 years following the index MI. 

The study has several limitations, the authors noted, including its observational nature, some missing clinical data, no data on the use of over-the-counter aspirin, and no way to determine if patients adhered to their prescription. However, a strength of the study is that these data are from one country and are known to be accurate, they said. 

They concluded that their findings support previous results that suggest there is "no apparent safe treatment window" for NSAIDs among patients with MI. 

20. Emergency Cricothyroidotomy: A Randomized Crossover Trial Comparing Percutaneous Techniques: Classic Needle First Versus “Incision First” 

Kanji H, et al. Acad Emerg Med. 2012;19:E1061–E1067.  

Objectives:  Emergency cricothyroidotomy is potentially lifesaving in patients with airway compromise who cannot be intubated or ventilated by conventional means. The literature remains divided on the best insertion technique, namely, the open/surgical and percutaneous methods. The two are not mutually exclusive, and the study hypothesis was that an “incision-first” modification (IF) may improve the traditional needle-first (NF) percutaneous approach. This study assessed the IF technique compared to the NF method. 

Methods:  A randomized controlled crossover design with concealed allocation was completed for 180 simulated tracheal models. Attending and resident emergency physicians were enrolled. The primary outcome was time to successful cannulation; secondary outcomes included needle insertion(s), incision, and dilatation attempts. Finally, proportions of intratracheal insertion on the first attempt and subjective ease of insertion were compared. 

Results:  The IF technique was significantly faster than the standard NF technique (median = 53 seconds, interquartile range [IQR] = 45.0 to 86.4 seconds vs. median = 90 seconds, IQR = 55.2 to 108.6 seconds; p less than 0.001). The median number of needle insertions was significantly higher for the NF technique (p = 0.018); there was no significant difference in dilation or incision attempts. Intratracheal insertion on the first attempt was documented in 90 and 93% of the NF and IF techniques, respectively (p = 0.317). All the study participants found the IF hybrid approach easier. 

Conclusions:  The IF modification allows faster access, fewer complications, and more favorable clinician endorsement than the classic NF percutaneous technique in a validated model of cricothyroidotomy. We suggest therefore that the IF technique be considered as an improved method for insertion of an emergency cricothyroidotomy. 

21. AAP Reaffirms Position against Trampoline Use 

Larry Hand.  Medscape Medical News. September 24, 2012 — The American Academy of Pediatrics (AAP) has reaffirmed its position opposing recreational use of trampolines in a policy statement published online September 24 in Pediatrics. 

Coauthors Susannah Briskin, MD, and Michele LaBotz, MD, both pediatricians and sports medicine physicians, write, "Although trampoline injury rates have been decreasing since 2004, the potential for severe injury remains relatively high." 

They write that trampoline injury rates were 70 per 100,000 for 0- to 4-year-olds in 2009, increasing to 160 per 100,000 for 5- to 14-year-olds. Injury rates for those ages are similar for bicycling or playground equipment, as well as swimming pools. However, the authors write, population exposure is "significantly greater" for bicycling and playground equipment, and evidence-based safety advisories for swimming pools are broadly publicized, whereas such advisories for trampolines are not as well disseminated. 

Multiple Users, Smallest Jumpers Most Susceptible 

Most trampoline injuries occur when multiple people are using it at the same time, and the smallest individuals are up to 14 times more vulnerable to injury because of weight differences and their less-developed motor skills, according to the statement. Falling accounts for between 27% and 39% of injuries, and the risk for falling rises when the trampoline in use is on an uneven surface. 

Use of padding does not seem to abate the risk for injury, and a third to a half of all injuries occur under adult supervision, the authors write. Children younger than 6 years account for between 22% and 37% of injuries presenting to emergency departments. 

Although foot and ankle injuries, such as ankle sprain, are most common (more than 60% in one study), 10% to 17% of injuries affect the head or neck, "and 0.5% of all trampoline injuries resulted in permanent neurologic damage," the authors warn. 

Several recommendations are contained in the policy statement, including:
·         Pediatricians should advise against recreational trampoline use.
·         Homeowners should verify whether trampoline injuries are covered by their insurance policies.
·         Any trampoline use should be restricted to a single user at a time.
·         Adults familiar with safety guidelines should supervise any trampoline use.
·         Trampoline conditions should be inspected regularly, and trampolines in disrepair should be discarded. 

The policy statement also says that until further safety information is available on trampoline parks and structured trampoline sports programs, "the cautions outlined here" should be observed for those as well. 

The AAP previously issued policy statements on trampoline use in 1977, 1981, and 1999. Injury rates are based on injuries reported to the US Consumer Product Safety Commission's National Electronic Injury Surveillance System. However, no data source exists regarding injuries in structured trampoline sports programs. 

In summary, "Pediatricians need to actively discourage recreational trampoline use. Families need to know that many injuries occur on the mat itself, and current data do not appear to demonstrate that netting or padding significantly decrease the risk of injury," Dr. LaBotz said in a news release. 

The authors have disclosed no relevant financial relationships.

22. Wanna Get Your Video-addicted Kids Some Exercise?

Physiologic Responses and Energy Expenditure of Kinect Active Video Game Play in Schoolchildren 

Smallwood SR, et al. Arch Pediatr Adolesc Med. Published online September 24, 2012. doi:10.1001/archpediatrics.2012.1271 

Objective:  To evaluate the physiologic responses and energy expenditure of active video gaming using Kinect for the Xbox 360. 

Design:  Comparison study. 

Setting:  Kirkby Sports College Centre for Learning, Liverpool, England. 

Participants:  Eighteen schoolchildren (10 boys and 8 girls) aged 11 to 15 years. 

Main Exposure:  A comparison of a traditional sedentary video game and 2 Kinect activity-promoting video games, Dance Central and Kinect Sports Boxing, each played for 15 minutes. Physiologic responses and energy expenditure were measured using a metabolic analyzer. 

Main Outcome Measures:  Heart rate, oxygen uptake, and energy expenditure. 

Results:  Heart rate, oxygen uptake, and energy expenditure were considerably higher (P less than .05) during activity-promoting video game play compared with rest and sedentary video game play. The mean (SD) corresponding oxygen uptake values for the sedentary, dance, and boxing video games were 6.1 (1.3), 12.8 (3.3), and 17.7 (5.1) mL · min–1 · kg–1, respectively. Energy expenditures were 1.5 (0.3), 3.0 (1.0), and 4.4 (1.6) kcal · min–1, respectively.

Conclusions:  Dance Central and Kinect Sports Boxing increased energy expenditure by 150% and 263%, respectively, above resting values and were 103% and 194% higher than traditional video gaming. This equates to an increased energy expenditure of up to 172 kcal · h–1 compared with traditional sedentary video game play. Played regularly, active gaming using Kinect for the Xbox 360 could prove to be an effective means for increasing physical activity and energy expenditure in children.
