0. From BMJ’s Annual Light-hearted Christmas Issue

Preface: “If 2018 can be summed up by the Oxford Dictionaries word of the year—“toxic”—we hope that generosity and compassion can serve as an antidote. We have a few ideas for giving and sharing, inspired by the articles in this year’s festive edition of the journal.

Abi Rimmer asked several prominent doctors about moments of compassion that have helped to brighten a busy and stressful day (https://www.bmj.com/content/363/bmj.k5136). We’re asking readers to share their own acts of kindness: please do post a response to the article, or join us on social media using #BMJchristmaskindness.

The Christmas issue of The BMJ is a time for our more humorous authors to share their work. Satirically minded readers should look out…


A. Surgeons are the best physician golfers

Koplewitz G, et al. Golf habits among physicians and surgeons: observational cohort study. BMJ 2018;363:k4859

Objectives To examine patterns of golfing among physicians: the proportion who regularly play golf, differences in golf practices across specialties, the specialties with the best golfers, and differences in golf practices between male and female physicians.

Design Observational study.

Setting Comprehensive database of US physicians linked to the US Golfing Association amateur golfer database.

Participants 41 692 US physicians who actively logged their golf rounds in the US Golfing Association database as of 1 August 2018.

Main outcome measures Proportion of physicians who play golf, golf performance (measured using golf handicap index), and golf frequency (number of games played in previous six months).

Results Among 1 029 088 physicians, 41 692 (4.1%) actively logged golf scores in the US Golfing Association amateur golfer database. Men accounted for 89.5% of physician golfers, and among male physicians overall, 5.5% (37 309/683 297) played golf compared with 1.3% (4383/345 489) among female physicians. Rates of golfing varied substantially across physician specialties. The highest proportions of physician golfers were in orthopedic surgery (8.8%), urology (8.1%), plastic surgery (7.5%), and otolaryngology (7.1%), whereas the lowest proportions were in internal medicine and infectious disease (less than 3.0%). Physicians in thoracic surgery, vascular surgery, and orthopedic surgery were the best golfers, with about 15% better golf performance than specialists in endocrinology, dermatology, and oncology.

Conclusions Golfing is common among US male physicians, particularly those in the surgical subspecialties. The association between golfing and patient outcomes, costs of care, and physician wellbeing remain unknown.

B. Christmas, national holidays, sport events, and time factors as triggers of acute myocardial infarction: SWEDEHEART observational study 1998-2013

Mohammad MA, et al. BMJ 2018;363:k4811

Objectives To study circadian rhythm aspects, national holidays, and major sports events as triggers of myocardial infarction….

Conclusions In this nationwide real world study covering 16 years of hospital admissions for myocardial infarction with symptom onset documented to the nearest minute, Christmas, and Midsummer holidays were associated with higher risk of myocardial infarction, particularly in older and sicker patients, suggesting a role of external triggers in vulnerable individuals.


C. Holiday Weight Gain is Preventable

Mason F, et al. Effectiveness of a brief behavioural intervention to prevent weight gain over the Christmas holiday period: randomised controlled trial. BMJ 2018;363:k4867

Objective To test the effectiveness of a brief behavioural intervention to prevent weight gain over the Christmas holiday period…

Conclusion A brief behavioural intervention involving regular self weighing, weight management advice, and information about the amount of physical activity required to expend the calories in festive foods and drinks prevented weight gain over the Christmas holiday period.


D. Holiday Hospitalizations are Dangerous

Lapointe-Shaw L, et al. Death and readmissions after hospital discharge during the December holiday period: cohort study. BMJ 2018;363:k4481

Objective To determine whether patients discharged from hospital during the December holiday period have fewer outpatient follow-ups and higher rates of death or readmission than patients discharged at other times….

Conclusions Patients discharged from hospital during the December holiday period are less likely to have prompt outpatient follow-up and are at higher risk of death or readmission within 30 days.

E. Parachute use to prevent death and major trauma when jumping from aircraft: RCT

Yeh RW, et al. BMJ 2018;363:k5094

Objective To determine if using a parachute prevents death or major traumatic injury when jumping from an aircraft.

Design Randomized controlled trial.

Setting Private or commercial aircraft between September 2017 and August 2018.

Participants 92 aircraft passengers aged 18 and over were screened for participation. 23 agreed to be enrolled and were randomized.

Intervention Jumping from an aircraft (airplane or helicopter) with a parachute versus an empty backpack (unblinded).

Main outcome measures Composite of death or major traumatic injury (defined by an Injury Severity Score over 15) upon impact with the ground measured immediately after landing.

Results Parachute use did not significantly reduce death or major injury (0% for parachute v 0% for control; P greater than 0.9). This finding was consistent across multiple subgroups. Compared with individuals screened but not enrolled, participants included in the study were on aircraft at significantly lower altitude (mean of 0.6 m for participants v mean of 9146 m for non-participants; P less than 0.001) and lower velocity (mean of 0 km/h v mean of 800 km/h; P less than 0.001).

Conclusions Parachute use did not reduce death or major traumatic injury when jumping from aircraft in the first randomized evaluation of this intervention. However, the trial was only able to enroll participants on small stationary aircraft on the ground, suggesting cautious extrapolation to high altitude jumps. When beliefs regarding the effectiveness of an intervention exist in the community, randomized trials might selectively enroll individuals with a lower perceived likelihood of benefit, thus diminishing the applicability of the results to clinical practice.


1. The Additive Value of Pelvic Examinations to History in Predicting STI for Young Female Patients with Suspected Cervicitis or PID

Farrukh S, Onogul B, et al. Ann Emerg Med. 2018 Dec;72(6):703-712.e1.

STUDY OBJECTIVE:
We evaluate the additive value of pelvic examinations in predicting sexually transmitted infection for young female patients with suspected cervicitis or pelvic inflammatory disease in a pediatric emergency department (ED).

METHODS:
This was a prospective observational study of female patients aged 14 to 20 years who presented to an urban academic pediatric ED with a complaint of vaginal discharge or lower abdominal pain. Enrolled patients provided a urine sample for chlamydia, gonorrhea, and trichomonas testing, which served as the criterion standard for diagnosis. A practitioner (pediatric ED attending physician, emergency medicine or pediatric resident, pediatric ED fellow, or advanced practice provider) obtained a standardized history from the patient to assess for cervicitis or pelvic inflammatory disease according to the Centers for Disease Control and Prevention criteria. They then recorded the likelihood of cervicitis or pelvic inflammatory disease on a 100-mm visual analog scale. The same practitioner then performed a pelvic examination and again recorded the likelihood of cervicitis or pelvic inflammatory disease on a visual analog scale with this additional information. Using the results of the urine sexually transmitted infection tests, the practitioner calculated and compared the test characteristics of history alone and history with pelvic examination.

RESULTS:
Two hundred eighty-eight patients were enrolled, of whom 79 had positive urine test results for chlamydia, gonorrhea, or trichomonas, with a sexually transmitted infection rate of 27.4% (95% confidence interval [CI] 22.6% to 32.8%). The sensitivity of history alone in diagnosis of cervicitis or pelvic inflammatory disease was 54.4% (95% CI 42.8% to 65.5%), whereas the specificity was 59.8% (95% CI 52.8% to 66.4%). The sensitivity of history with pelvic examination in diagnosis of cervicitis or pelvic inflammatory disease was 48.1% (95% CI 36.8% to 59.5%), whereas the specificity was 60.7% (95% CI 53.8% to 67.3%). The information from the pelvic examination changed management in 71 cases; 35 of those cases correlated with the sexually transmitted infection test and 36 did not.

CONCLUSION:
For young female patients with suspected cervicitis or pelvic inflammatory disease, the pelvic examination does not increase the sensitivity or specificity of diagnosis of chlamydia, gonorrhea, or trichomonas compared with taking a history alone. Because the test characteristics for the pelvic examination are not adequate, its routine performance should be reconsidered.

2. Real World Evidence for Treatment of Hyperkalemia in the ED (REVEAL–ED): A Multicenter, Prospective, Observational Study

Peacock WF, et al. J Emerg Med. 2018 Dec;55(6):741-750. doi:

BACKGROUND:
Contemporary emergency department (ED) standard-of-care treatment of hyperkalemia is poorly described.

OBJECTIVE:
Our aim was to determine the treatment patterns of hyperkalemia management in the ED.

METHODS:
This multicenter, prospective, observational study evaluated patients aged ≥ 18 years with hyperkalemia (potassium [K+] level ≥ 5.5 mmol/L) in the ED from October 25, 2015 to March 30, 2016. K+-lowering therapies and K+ were documented at 0.5, 1, 2, and 4 h after initial ED treatment. The primary end point was change in K+ over 4 h.

RESULTS:
Overall, 203 patients were enrolled at 14 U.S.-based sites. The initial median K+ was 6.3 (interquartile range [IQR] 5.7-6.8) mmol/L and median time to treatment was 2.7 (IQR 1.9-3.5) h post-ED arrival. Insulin/glucose (n = 130; 64%) was frequently used to treat hyperkalemia; overall, 43 different treatment combinations were employed within the first 4 h. Within 4 h, the median K+ for patients treated with medications alone decreased from 6.3 (IQR, 5.8-6.8) mmol/L to 5.3 (4.8-5.7) mmol/L, while that for patients treated with dialysis decreased from 6.2 (IQR 6.0-6.6) mmol/L to 3.8 (IQR 3.6-4.2) mmol/L. Hypoglycemia occurred in 6% of patients overall and in 17% of patients with K+ greater than 7.0 mmol/L. Hyperkalemia-related electrocardiogram changes were observed in 23% of all patients; 45% of patients with K+ greater than 7.0 mmol/L had peaked T waves or widened QRS. Overall, 79% were hospitalized; 3 patients died.

CONCLUSIONS:
Hyperkalemia practice patterns vary considerably and, although treatment effectively lowered K+, only dialysis normalized median K+ within 4 h.


3. Cardiac Corner

A. Cancellation of the Cardiac Cath Lab After Activation for STEMI

Lange DC, et al. Circ Cardiovasc Qual Outcomes. 2018 Aug;11(8):e004464.

BACKGROUND:
Prehospital ECG-based cardiac catheterization laboratory (CCL) activation for ST-segment-elevation myocardial infarction reduces door-to-balloon times, but CCL cancellations (CCLX) remain a challenging problem. We examined the reasons for CCLX, clinical characteristics, and outcomes of patients presenting as ST-segment-elevation myocardial infarction activations who receive emergent coronary angiography (EA) compared with CCLX.

METHODS AND RESULTS:
We reviewed all consecutive CCL activations between January 1, 2012, and December 31, 2014 (n=1332). Data were analyzed comparing 2 groups stratified as EA (n=466) versus CCLX (n=866; 65%). Reasons for CCLX included bundle branch block (21%), poor-quality prehospital ECG (18%), non-ST-segment-elevation myocardial infarction ST changes (18%), repolarization abnormality (13%), and arrhythmia (8%). A multivariate logistic regression model using age, peak troponin, and initial ECG findings had a high discriminatory value for determining EA versus CCLX (C statistic, 0.985). CCLX subjects were older and more likely to be women, have prior coronary artery bypass grafting, or a paced rhythm (P less than 0.0001 for all). All-cause mortality did not differ between groups at 1 year or during the study period (mean follow-up, 2.186±1.167 years; 15.8% EA versus 16.2% CCLX; P=0.9377). Cardiac death was higher in the EA group (11.8% versus 3.0%; P less than 0.0001). After adjusting for clinical variables associated with survival, CCLX was associated with an increased risk for all-cause mortality during the study period (hazard ratio, 1.82; 95% CI, 1.28-2.59; P=0.0009).

CONCLUSIONS:
In this study, prehospital ECG without overreading or transmission lead to frequent CCLX. CCLX subjects differ with regard to age, sex, risk factors, and comorbidities. However, CCLX patients represent a high-risk population, with frequently positive cardiac enzymes and similar short- and long-term mortality compared with EA. Further studies are needed to determine how quality improvement initiatives can lower the rates of CCLX and influence clinical outcomes.

B. European Resuscitation Council Guidelines for Resuscitation: 2018 Update – Antiarrhythmic drugs for cardiac arrest

Soar J, et al. Resuscitation 2018 Nov 26 [Epub ahead of print]

Abstract
This European Resuscitation Council (ERC) Guidelines for Resuscitation 2018 update is focused on the role of antiarrhythmic drugs during advanced life support for cardiac arrest with shock refractory ventricular fibrillation/pulseless ventricular tachycardia in adults, children and infants. This update follows the publication of the International Liaison Committee on Resuscitation (ILCOR) 2018 International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science with Treatment Recommendations (CoSTR). The ILCOR CoSTR suggests that any beneficial effects of amiodarone or lidocaine are similar. This ERC update does not make any major changes to the recommendations for the use of antiarrhythmic drugs during advanced life support for shock refractory cardiac arrest.

Excerpt
We recommend that amiodarone is given after three defibrillation attempts irrespective of whether they are consecutive shocks or interrupted by CPR, or for recurrent VF/pVT during cardiac arrest. An antiarrhythmic drug can be used in cases of a primary shockable rhythm, or when a shockable rhythm follows a primary shockable cardiac arrest. Give amiodarone 300 mg intravenously; a further dose of 150 mg may be given after five defibrillation attempts. Lidocaine (100 mg) may be used if amiodarone is not available or a local decision has been made to use lidocaine instead of amiodarone. An additional bolus of lidocaine 50 mg may also be given after five defibrillation attempts.


C. Evaluation of a novel cardioversion intervention for AF: the Ottawa AF cardioversion protocol

Ramirez FD, et al. EP Europace. 2018 Dec 7 [Epub ahead of print]

Aims
Electrical cardioversion is commonly performed to restore sinus rhythm in patients with atrial fibrillation (AF), but it is unsuccessful in 10–12% of attempts. We sought to evaluate the effectiveness and safety of a novel cardioversion protocol for this arrhythmia.

Methods and results
Consecutive elective cardioversion attempts for AF between October 2012 and July 2017 at a tertiary cardiovascular centre before (Phase I) and after (Phase II) implementing the Ottawa AF cardioversion protocol (OAFCP) as an institutional initiative in July 2015 were evaluated. The primary outcome was cardioversion success, defined as ≥2 consecutive sinus beats or atrial-paced beats in patients with implanted cardiac devices. Secondary outcomes were first shock success, sustained success (sinus or atrial-paced rhythm on 12-lead electrocardiogram prior to discharge from hospital), and procedural complications. Cardioversion was successful in 459/500 (91.8%) in Phase I compared with 386/389 (99.2%) in Phase II (P less than 0.001). This improvement persisted after adjusting for age, body mass index, amiodarone use, and transthoracic impedance using modified Poisson regression [adjusted relative risk 1.08, 95% confidence interval (CI) 1.05–1.11; P less than 0.001] and when analysed as an interrupted time series (change in level +9.5%, 95% CI 6.8–12.1%; P less than 0.001). The OAFCP was also associated with greater first shock success (88.4% vs. 79.2%; P less than  0.001) and sustained success (91.6% vs 84.7%; P=0.002). No serious complications occurred.

Conclusion
Implementing the OAFCP was associated with a 7.4% absolute increase in cardioversion success and increases in first shock and sustained success without serious procedural complications. Its use could safely improve cardioversion success in patients with AF.

About the Ottawa AF protocol
The Ottawa AF protocol prescribes the electrical energy dose, the electrode position and the application of pressure to the electrodes the physician will use. The individual elements of the protocol (energy dose, electrode position and pressure application) are often used by physician in clinical practice but not necessarily in the step by step order.

The Ottawa AF cardioversion protocol consists of four sequential steps
1. 200 J shock delivered using self-adhesive electrodes in an anteroposterior position*;
2. 200 J shock delivered with self-adhesive electrodes in an anterolateral position with manual force applied to the electrodes using standard, disconnected, handheld defibrillation paddles (operator instructed to apply a force equivalent to a ‘push-up’);
3. 360 J shock delivered with self-adhesive electrodes in an anterolateral position with the same
prompt as in Step 2;
4. Further shock(s) at the treating physician’s discretion.

*Anterior electrode placement was prescribed as immediately adjacent to the sternum, below the right clavicle. Posterior electrode placement was prescribed as immediately to the left of the spine, at the level of the heart.

This was not in the protocol. But facilities that don’t have paddle access can try Manual Pressure Augmentation (MPA): The MPA technique is simple—apply manual force to the adhesive patches with gloved hands for cardioversion during end-exhalation. MPA is safe, causing no injury to the provider. See Voskoboinik A,  et al. Cardioversion of atrial fibrillation in obese patients: results from the Cardioversion-BMI randomized controlled trial.

5. Pediatric Corner

A. Apneic oxygenation reduces hypoxemia during endotracheal intubation in the pediatric ED

Vukovic AA, et al. Am J Emerg Med. 2019;37(1):27-32.

Background
Apneic oxygenation (AO) has been evaluated in adult patients as a means of reducing hypoxemia during endotracheal intubation (ETI). While less studied in pediatric patients, its practice has been largely adopted.

Objective
Determine association between AO and hypoxemia in pediatric patients undergoing ETI.

Methods
Observational study at an urban, tertiary children's hospital emergency department. Pediatric patients undergoing ETI were examined during eras without (January 2011–June 2011) and with (August 2014–March 2017) apneic oxygenation. The primary outcome was hypoxemia, defined as pulse oximetry (SpO2)  less than 90%. The χ2 and Wilcoxon rank-sum tests examined differences between cohorts. Multivariable regression models examined adjusted associations between covariates and hypoxemia.

Results
149 patients were included. Cohorts were similar except for greater incidence of altered mental status in those receiving AO (26% vs. 7%, p = 0.03). Nearly 50% of the pre-AO cohort experienced hypoxemia during ETI, versus less than 25% in the AO cohort. Median [IQR] lowest SpO2 during ETI was 93 (69, 99) for pre-AO and 100 [95, 100] for the AO cohort (p  less than 0.001). In a multivariable logistic regression model, hypoxemia during ETI was associated with AO (aOR 0.3, 95% confidence interval [CI] 0.1–0.8), increased age (for 1 year, aOR 0.8, 95% CI 0.7–1.0), lowest SpO2 before ETI (for 1% increase, aOR 0.9, 95% CI 0.8–1.0), and each additional intubation attempt (aOR 4.0, 95% CI 2.2–7.2).

Conclusions
Apneic oxygenation is an easily-applied intervention associated with decreases in hypoxemia during pediatric ETI. Nearly 50% of children not receiving AO experienced hypoxemia.

B. The Sonographic Appearance of Spinal Fluid at Clinically Selected Interspaces in Sitting Versus Lateral Positions.

Vitberg YM, et al. Pediatr Emerg Care. 2018;34(5):334-338.

OBJECTIVE:
Our objective was to describe the sonographic appearance of fluid at clinically selected interspinous spaces and see if additional interspaces could be identified as suitable and safe targets for needle insertion. We also measured the reproducibility of fluid measurements and assessed for positional differences.

METHODS:
A prospective convenience sample of infants younger than 3 months was enrolled in the pediatric emergency department. Excluded were clinically unstable infants or those with spinal dysraphism. Infants were first held in standard lateral lumbar puncture position. Pediatric emergency medicine (PEM) physicians marked infants' backs at the level they would insert a needle using the landmark palpation technique. A PEM sonologist imaged and measured the spinal fluid in 2 orthogonal planes at this marked level in lateral then sitting positions. Fluid measurements were repeated by a second blinded PEM sonologist.

RESULTS:
Forty-six infants were enrolled. Ultrasound verified the presence of fluid at the marked level as determined by the landmark palpation technique in 98% of cases. Ultrasound identified additional suitable spaces 1 space higher (82%) and 2 spaces higher (41%). Intraclass correlation coefficient of all measurements was excellent (greater than 0.85), with differences noted for sitting versus lateral position in mean area of fluid 0.34 mm versus 0.31 mm (difference, 0.03; 95% confidence interval [CI], 0.005-0.068), dorsal fluid pocket 0.23 mm versus 0.15 mm (difference, 0.08; 95% CI, 0.031-0.123), and nerve root-to-canal ratio 0.44 versus 0.51 (difference, 0.07; 95% CI, 0.004-0.117).

CONCLUSIONS:
Ultrasound can verify the presence of fluid at interspaces determined by the landmark palpation technique and identify additional suitable spaces at higher levels. There were statistically greater fluid measurements in sitting versus lateral positions. These novel fluid measurements were shown to be reliable.

Pediatric lumbar puncture can be challenging or unsuccessful for several reasons. At the same time, the excellent sonographic window into the pediatric spine provides a distinct opportunity for ultrasound-guided lumbar puncture. Minimal cerebrospinal fluid and thecal displacement by subdural or epidural hematomas are common after failed clinical attempts. Ultrasound is useful for determining a safe infraconal level for subarachnoid access. Real-time guidance increases not only the success rate but also the safety of diagnostic lumbar puncture and injections for chemotherapy and myelography. In this article, we discuss clinical and technical factors for ultrasound-guided pediatric lumbar puncture.

C. Pediatric Ingestions of Novel Antithrombotic Agents Are Usually Not Dangerous

Among 638 “exploratory” ingestions over 10 years in four states there were no bleeding complications.

Levine M et al. Exploratory Ingestions of Novel Anticoagulants and Antiplatelets: What Is the Risk? Pediatr Emerg Care 2018 Nov 19 [Epub ahead of print]

BACKGROUND:
Historically, anticoagulants and antiplatelet agents included warfarin and aspirin, respectively. In recent years, numerous novel anticoagulants (eg, direct thrombin inhibitors and factor Xa inhibitors) as well as the adenosine diphosphate receptor antagonists have increased significantly. Little information on the bleeding risk after exploratory ingestion of these agents is available. The primary purpose of this study is to evaluate the bleeding risk of these agents after an exploratory ingestion in children 6 years or younger.

METHODS:
This retrospective multicenter poison control center study was conducted on calls between 2005 and 2014. The following agents were included: apixaban, clopidogrel, dabigatran, edoxaban, prasugrel, rivaroxaban, or ticagrelor. Bleeding characteristics and treatment rendered were recorded.

RESULTS:
A total of 638 cases were identified. Most cases involved antiplatelet agents. No patient developed any bleeding complication. The administration of charcoal was independent of the amount of drug ingested.

CONCLUSION:
Accidental, exploratory ingestions of these agents seem well tolerated, with no patient developing bleeding complications.

D. Most Children Admitted To Non-Children’s Hospitals With CAP May Not Receive Antibiotics In Accordance With Guidelines

Tribble AC, et al. Comparison of Antibiotic Prescribing for Pediatric Community-Acquired Pneumonia in Children’s and Non-Children’s Hospitals. JAMA Pediatr.  2018 Dec 10 [Epub ahead of print]

Pneumonia is the most common indication for antibiotic use in hospitalized children. National guidelines for community-acquired pneumonia (CAP) recommend penicillin, amoxicillin, and ampicillin as first-line agents for children hospitalized with CAP. Although use of these agents for CAP is increasing in children’s hospitals, antibiotic prescribing trends for children admitted to non-children’s hospitals, where 70% of hospitalized children receive care,4 are unknown. We compared antibiotic prescribing for CAP between hospital types before and after guideline publication in 2011. Four years after publication of national pediatric CAP guidelines, only 27% of children admitted to non-children’s hospitals received guideline-concordant therapy compared with 61% in children’s hospitals.

The reason for these discrepancies in guideline-concordant prescribing is not known, the authors write. "It is unlikely attributable to differences in patient populations because we included only healthy children with uncomplicated CAP and adjusted for potential confounders. Studies in children's hospitals have suggested that local implementation efforts may be important in facilitating guideline uptake. Non-children's hospitals likely have fewer resources to lead pediatric-specific efforts, and care may be influenced by adult CAP guidelines," they explain.


E. Bacterial meningitis score inadequate in infants aged 0 to 60 days

Rees CA, et al. J Pediatric Infect Dis Soc. 2018 Dec 19 [Epub ahead of print]

A recent study found that the bacterial meningitis score had high sensitivity but poor specificity when identifying bacterial meningitis in infants aged 0 to 60 days.

“The bacterial meningitis score is a widely validated clinical prediction rule for identifying children with [cerebrospinal fluid (CSF)] pleocytosis who are very low risk for bacterial meningitis,” Chris A. Rees, MD, MPH, clinical fellow in pediatric emergency medicine at Boston Children’s Hospital, told Infectious Diseases in Children. “However, based on the results of our study of 4,292 infants 60 days of age or younger with CSF pleocytosis, the specificity of the bacterial meningitis score was too low for this clinical prediction rule to be applied clinically in this age group.


F. Prone positioning for children with severe bronchiolitis

The prone position significantly decreases mortality in adults with severe acute respiratory distress syndrome and improves oxygenation and may improve respiratory mechanics and gas exchange in adults with chronic bronchitis. Prone positioning has been proposed in infants with severe bronchiolitis. This randomized cross-over study found that the prone position can decrease inspiratory effort and the metabolic cost of breathing. Indicators of inspiratory effort were lower in the prone position than the supine position, and they decreased over time more efficiently in the prone position. All mechanical, neural, and clinical measures showed that breathing was easier in the prone position.


6. Clinical validation of a risk scale for serious outcomes among patients with COPD managed in the ED

Stiell IG, et al. CMAJ. 2018;190(48):E1406-E1413

BACKGROUND: The Ottawa chronic obstructive pulmonary disease (COPD) Risk Scale (OCRS), which consists of 10 criteria, was previously derived to identify patients in the emergency department with COPD who were at high risk for short-term serious outcomes. We sought to validate, prospectively and explicitly, the OCRS when applied by physicians in the emergency department.

METHODS: We conducted this prospective cohort study involving patients in the emergency departments at 6 tertiary care hospitals and enrolled adults with acute exacerbation of COPD from May 2011 to December 2013. Physicians evaluated patients for the OCRS criteria, which were recorded on a data form along with the total risk score. We followed patients for 30 days and the primary outcome, short-term serious outcomes, was defined as any of death, admission to monitored unit, intubation, noninvasive ventilation, myocardial infarction (MI) or relapse with hospital admission.

RESULTS: We enrolled 1415 patients with a mean age of 70.6 (SD 10.6) years and 50.2% were female. Short-term serious outcomes occurred in 135 (9.5%) cases. Incidence of short-term serious outcomes ranged from 4.6% for a total score of 0 to 100% for a score of 10. Compared with current practice, an OCRS score threshold of greater than 1 would increase sensitivity for short-term serious outcomes from 51.9% to 79.3% and increase admissions from 45.0% to 56.6%. A threshold of greater than 2 would improve sensitivity to 71.9% with 47.9% of patients being admitted.

INTERPRETATION: In this clinical validation of a risk-stratification tool for COPD in the emergency department, we found that OCRS showed better sensitivity for short-term serious outcomes compared with current practice. This risk scale can now be used to help emergency department disposition decisions for patients with COPD, which should lead to a decrease in unnecessary admissions and in unsafe discharges. 





7. Emergency 'MacGyver' Tips for Physicians

Robert Glatter, MD; Amy Faith Ho, MD. Medscape. December 03, 2018

Robert D. Glatter, MD: A large part of being an emergency medicine physician is being a problem solver, being innovative and resourceful, and trying to make the best of a challenging clinical situation—often with the lack of complete information or equipment. The spirit of what we do on a daily basis is reflected in the character of a popular TV series, MacGyver, which aired decades ago but was rebooted in 2016.

Dr Amy Ho fits the bill of a problem solver, so much so that she came up with the concept of what a character such as MacGyver would do if he didn't have exactly what he needed to solve a problem—a topic of one of her past ACEP [American College of Emergency Physicians] talks.

Dr Ho is a recent graduate of the University of Chicago Emergency Medicine residency and is newly clinical faculty and associate medical director at John Peter Smith Hospital, a level-1 trauma center in Fort Worth, Texas. Welcome, Dr Ho.

8. Foregoing Surgery for Appendicitis? What Do Patients Prefer?

Hanson AL, et al. Patient Preferences for Surgery or Antibiotics for the Treatment of Acute Appendicitis. JAMA Surg. 2018;153(5):471-478.

IMPORTANCE:
Studies have compared surgical with nonsurgical therapy for acute uncomplicated appendicitis, but none of these studies have a patient-centered perspective.

OBJECTIVES:
To evaluate how patients might choose between surgical and nonsurgical therapy for acute uncomplicated appendicitis and to identify targets to make antibiotic treatment more appealing.

DESIGN, SETTING, AND PARTICIPANTS:
This study comprised an online survey and an in-person sensitivity analysis survey. For the web survey, a convenience sample of 1728 respondents were asked to imagine that they or their child had acute uncomplicated appendicitis, provided information about laparoscopic and open appendectomy and antibiotic treatment alone, and asked which treatment they might choose. The web survey was open from April 17, 2016, through June 16, 2016, and was disseminated via email link, a poster with a Quick Response code, and social media. For the sensitivity analysis, 220 respondents were given the same scenario and options. Those who chose surgery were asked whether certain factors influenced their decision; each factor was incrementally improved during questioning about whether respondents would consider switching to antibiotics. These participants were recruited at public venues from June 3, 2016, to July 31, 2016. Web survey data were analyzed from June 17, 2016, to September 21, 2017. Sensitivity analysis data were analyzed from August 1, 2016, to September 21, 2017.

MAIN OUTCOMES AND MEASURES:
Treatment preferences.

RESULTS:
Among the 1728 web survey respondents, 1225 (70.9%) were female and 500 (28.9%) were male (3 [0.2%] either did not answer or responded as "gender fluid" within the comments section of the survey), and most self-reported being between 50 and 59 years of age (391 [22.6%]) and being non-Hispanic white (1563 [90.5%]). For themselves, 1482 respondents (85.8%) chose laparoscopic appendectomy, 84 (4.9%) chose open appendectomy, and 162 (9.4%) chose antibiotics alone. For their child, 1372 respondents (79.4%) chose laparoscopic appendectomy, 106 (6.1%) open appendectomy, and 250 (14.5%) antibiotics alone. Respondents were somewhat more likely to choose antibiotics for themselves if they had education beyond college (105 [12.6%]; P  less than .001), identified as other than non-Hispanic white (24 [14.9%]; P less than. 001), or did not know anyone who had previously been hospitalized (12 [15.8%]; P = .02), but they were less likely to choose antibiotics if they were surgeons (11 [5.4%]; P = .008). Of the 220 participants interviewed for the sensitivity analysis, 120 (54.5%) were female and 100 (45.5%) were male, and most self-reported being between 18 and 24 years of age (53 [24.1%]) and being non-Hispanic white (204 [92.7%]). Their responses suggested that improvements in the short- and long-term failure rate of antibiotic treatment-rather than reductions in the duration of hospitalization or antibiotic treatment-were more likely to increase the desirability of choosing antibiotics.

CONCLUSIONS AND RELEVANCE:
Most patients may choose surgical intervention over antibiotics alone in treatment of acute uncomplicated appendicitis, but a meaningful number may choose nonoperative management. Therefore, from a patient-centered perspective, this option should be discussed with patients, and future research could be directed at reducing the failure and recurrence rates of antibiotic treatment for appendicitis.

9. Pneumothorax

A. A Systematic Review and Meta-Analysis Comparing Pigtail Catheter and Chest Tube as the Initial Treatment for Pneumothorax.

Chang SH, et al. Chest. 2018 May;153(5):1201-1212.

BACKGROUND:
The optimal initial treatment approach for pneumothorax remains controversial. This systemic review and meta-analysis investigated the effectiveness of small-bore pigtail catheter (PC) drainage compared with that of large-bore chest tube (LBCT) drainage as the initial treatment approach for all subtypes of pneumothorax.

METHODS:
PubMed and Embase were systematically searched for observational studies and randomized controlled trials published up to October 9, 2017, that compared PC and LBCT as the initial treatment for pneumothorax. The investigative outcomes included success rates, recurrence rates, complication rates, drainage duration, and hospital stay.

RESULTS:
Of the 11 included studies (875 patients), the success rate was similar in the PC (79.84%) and LBCT (82.87%) groups, with a risk ratio of 0.99 (95% CI, 0.93 to 1.05; I2 = 0%). Specifically, PC drainage was associated with a significantly lower complication rate following spontaneous pneumothorax than LBCT drainage (Peto odds ratio: 0.49 [95% CI, 0.28 to 0.85]; I2 = 29%). In the spontaneous subgroup, PC drainage was associated with a significantly shorter drainage duration (mean difference, -1.51 [95% CI, -2.93 to -0.09]) and hospital stay (mean difference: -2.54 [95% CI, -3.16 to -1.92]; P less than .001) than the LBCT group.

CONCLUSIONS:
Collectively, results of the meta-analysis suggest PC drainage may be considered as the initial treatment option for patients with primary or secondary spontaneous pneumothorax. Ideally, randomized controlled trials are needed to compare PC vs LBCT among different subgroups of patients with pneumothorax, which may ultimately improve clinical care and management for these patients.

B. Pneumothorax and Hemothorax in the Era of Frequent Chest CT for the Evaluation of Adult Patients With Blunt Trauma

Rodriguez RM, et al. Ann Emerg Med. 2019;73(1):58-65.

STUDY OBJECTIVE:
Although traditional teachings in regard to pneumothorax and hemothorax generally recommend chest tube placement and hospital admission, the increasing use of chest computed tomography (CT) in blunt trauma evaluation may detect more minor pneumothorax and hemothorax that might indicate a need to modify these traditional practices. We determine the incidence of pneumothorax and hemothorax observed on CT only and the incidence of isolated pneumothorax and hemothorax (pneumothorax and hemothorax occurring without other thoracic injuries), and describe the clinical implications of these injuries.

METHODS:
This was a planned secondary analysis of 2 prospective, observational studies of adult patients with blunt trauma, NEXUS Chest (January 2009 to December 2012) and NEXUS Chest CT (August 2011 to May 2014), set in 10 Level I US trauma centers. Participants' inclusion criteria were older than 14 years, presentation to the emergency department (ED) within 6 hours of blunt trauma, and receipt of chest imaging (chest radiograph, chest CT, or both) during their ED evaluation. Exposure(s) (for observational studies) were that patients had trauma and chest imaging. Primary measures and outcomes included the incidence of pneumothorax and hemothorax observed on CT only versus on both chest radiograph and chest CT, the incidence of isolated pneumothorax and hemothorax (pneumothorax and hemothorax occurring without other thoracic injuries), and admission rates, hospital length of stay, mortality, and frequency of chest tube placement for these injuries.

RESULTS:
Of 21,382 enrolled subjects, 1,064 (5%) had a pneumothorax and 384 (1.8%) had a hemothorax. Of the 8,661 patients who received both a chest radiograph and a chest CT, 910 (10.5%) had a pneumothorax, with 609 (67%) observed on CT only; 319 (3.7%) had a hemothorax, with 254 (80%) observed on CT only. Of 1,117 patients with pneumothorax, hemothorax, or both, 108 (10%) had isolated pneumothorax or hemothorax. Patients with pneumothorax observed on CT only had a lower chest tube placement rate (30% versus 65%; difference in proportions [Δ] -35%; 95% confidence interval [CI] -28% to 42%), admission rate (94% versus 99%; Δ 5%; 95% CI 3% to 8%), and median length of stay (5 versus 6 days; difference 1 day; 95% CI 0 to 2 days) but similar mortality compared with patients with pneumothorax observed on chest radiograph and CT. Patients with hemothorax observed on CT had only a lower chest tube placement rate (49% versus 68%; Δ -19%; 95% CI -31% to -5%) but similar admission rate, mortality, and median length of stay compared with patients with hemothorax observed on chest radiograph and CT. Compared with patients with other thoracic injury, those with isolated pneumothorax or hemothorax had a lower chest tube placement rate (20% versus 43%; Δ -22%; 95% CI -30% to -13%), median length of stay (4 versus 5 days; difference -1 day; 95% CI -3 to 1 days), and admission rate (44% versus 97%; Δ -53%; 95% CI -62% to -43%), with an admission rate comparable to that of patients without pneumothorax or hemothorax (49%).

CONCLUSION:
Under current imaging protocols for adult blunt trauma evaluation, most pneumothoraces and hemothoraces are observed on CT only and few occur as isolated thoracic injury. The clinical implications (admission rates and frequency of chest tube placement) of pneumothorax and hemothorax observed on CT only and isolated pneumothorax or hemothorax are lower than those of patients with pneumothorax and hemothorax observed on chest radiograph and CT and of those who have other thoracic injury, respectively.

11. New Research on Soft Tissue Infections

A. Abscess Incision and Drainage With or Without US: A Randomized Controlled Trial.

Gaspari RJ, et al. Ann Emerg Med. 2019;73(1):1-7.

STUDY OBJECTIVE:
We hypothesize that clinical failure rates will be lower in patients treated with point-of-care ultrasonography and incision and drainage compared with those who undergo incision and drainage after physical examination alone.

METHODS:
We performed a prospective randomized clinical trial of patients presenting with a soft tissue abscess at a large, academic emergency department. Patients presenting with an uncomplicated soft tissue abscess requiring incision and drainage were eligible for enrollment and randomized to treatment with or without point-of-care ultrasonography. The diagnosis of an abscess was by physical examination, bedside ultrasonography, or both. Patients randomized to the point-of-care ultrasonography group had an incision and drainage performed with bedside ultrasonographic imaging of the abscess. Patients randomized to the non-point-of-care ultrasonography group had an incision and drainage performed with physical examination alone. Comparison between groups was by comparing means with 95% confidence intervals. The primary outcome was failure of therapy at 10 days, defined as a repeated incision and drainage, following a per-protocol analysis. Multivariate analysis was performed to control for study variables. Our study was designed to detect a clinically important difference between groups, which we defined as a 13% difference.

RESULTS:
A total of 125 patients were enrolled, 63 randomized to the point-of-care ultrasonography group and 62 to physical examination alone. After loss to follow-up and misallocation, 54 patients in the ultrasonography group and 53 in the physical examination alone group were analyzed. The overall failure rate for all patients enrolled in the study was 10.3%. Patients who were evaluated with ultrasonography were less likely to fail therapy and have repeated incision and drainage, with a difference between groups of 13.3% (95% confidence interval 0.0% to 19.4%). Abscess locations were predominantly torso (21%), buttocks (21%), lower extremity (18%), and axilla or groin (16%). There was no difference in baseline characteristics between groups relative to abscess size, duration of symptoms before presentation, percentage with cellulitis, and treatment with antibiotics.

CONCLUSION:
Patients with soft tissue abscesses who were undergoing incision and drainage with point-of-care ultrasonography demonstrated less clinical failure compared with those treated without point-of-care ultrasonography.

B. Systemic Antibiotics for the Treatment of Skin and Soft Tissue Abscesses: A Systematic Review and Meta-Analysis

Ann Emerg Med. 2019;72(1):8-16.

STUDY OBJECTIVE:
The addition of antibiotics to standard incision and drainage is controversial, with earlier studies demonstrating no significant benefit. However, 2 large, multicenter trials have recently been published that have challenged the previous literature. The goal of this review was to determine whether systemic antibiotics for abscesses after incision and drainage improve cure rates.

METHODS:
PubMed, the Cumulative Index of Nursing and Allied Health Literature, Scopus, the Cochrane Database of Systematic Reviews, the Cochrane Central Register of Controlled Trials, and bibliographies of selected articles were assessed for all randomized controlled trials comparing adjuvant antibiotics with placebo in the treatment of drained abscesses, with an outcome of treatment failure assessed within 21 days. Data were dual extracted into a predefined worksheet and quality analysis was performed with the Cochrane Risk of Bias tool.

RESULTS:
Four studies (n=2,406 participants) were identified. There were 89 treatment failures (7.7%) in the antibiotic group and 150 (16.1%) in the placebo group. The calculated risk difference was 7.4% (95% confidence interval [CI] 2.8% to 12.1%), with an odds ratio for clinical cure of 2.32 (95% CI 1.75 to 3.08) in favor of the antibiotic group. There was also a decreased incidence of new lesions in the antibiotic group (risk difference -10.0%, 95% CI -12.8% to -7.2%; odds ratio 0.32, 95% CI 0.23 to 0.44), with a minimally increased risk of minor adverse events (risk difference 4.4%, 95% CI 1.0% to 7.8%; odds ratio 1.29, 95% CI 1.06 to 1.58).

CONCLUSION:
The use of systemic antibiotics for skin and soft tissue abscesses after incision and drainage resulted in an increased rate of clinical cure. Providers should consider the use of antibiotics while balancing the risk of adverse events.


C. Is Loop Drainage Technique More Effective for Treatment of Soft Tissue Abscess Compared With Conventional Incision and Drainage?

Take-Home Message
Loop drainage technique may be associated with lower failure rate than conventional incision and drainage in treatment of skin and soft tissue abscesses, but data are limited. Further randomized controlled trial data are required.


D. What Is the Accuracy of Physical Examination, Imaging, and the LRINEC Score for the Diagnosis of Necrotizing Soft Tissue Infection?

Take-Home Message
Computed tomography (CT) has superior sensitivity compared with radiography for the diagnosis of necrotizing soft tissue infection, although different imaging findings have various diagnostic test characteristics. No single element of the physical examination, radiography, or the Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) score has sufficient sensitivity to exclude necrotizing soft tissue infection.


E. Identification of risk factors for failure in patients with skin and soft tissue infections

Cieri B, et al. Am J Emerg Med. 2019;37(1):48–52.

Purpose
The purpose was to determine significant predictors of treatment failure of skin and soft tissue infections (SSTI) in the inpatient and outpatient setting.

Methods
A retrospective chart review of patients treated between January 1, 2005 to July 1, 2016 with ICD-9 or ICD-10 code of cellulitis or abscess. The primary outcome was failure defined as an additional prescription or subsequent hospital admission within 30 days of treatment. Risk factors for failure were identified through multivariate logistic regression.

Results
A total of 541 patients were included. Seventeen percent failed treatment. In the outpatient group, 24% failed treatment compared to 9% for inpatients. Overweight/obesity (body mass index (BMI)  greater than  25 kg/m2) was identified in 80%, with 15% having a BMI greater than 40 kg/m2. BMI, heart failure, and outpatient treatment were determined to be significant predictors of failure. The unit odds ratio for failure with BMI was 1.04 (95% [Cl] = 1.01 to 1.1, p = 0.0042). Heart failure increased odds by 2.48 (95% [Cl] = 1.3 to 4.7, p = 0.0056). Outpatients were more likely to fail with an odds ratio of 3.36.

Conclusion
Patients with an elevated BMI and heart failure were found to have increased odds of failure with treatment for SSTIs. However, inpatients had considerably less risk of failure than outpatients. These risk factors are important to note when making the decision whether to admit a patient who presents with SSTI in the emergency department. Thoughtful strategies are needed with this at-risk population to prevent subsequent admission.

F. Identification of Clinical Characteristics Associated With High-Level Care Among Patients With Skin and Soft Tissue Infections

Mower WR, et al. Ann Emerg Med. 2018 Nov 9 [Epub ahead of print]

STUDY OBJECTIVE:
Serious adverse outcomes associated with skin and soft tissue infections are uncommon, and current hospitalization rates appear excessive. It would be advantageous to be able to differentiate between patients who require high-level inpatient services and those who receive little benefit from hospitalization. We sought to identify characteristics associated with the need for high-level inpatient care among emergency department patients presenting with skin and soft tissue infections.

METHODS:
We conducted a nonconcurrent review of existing records to identify emergency department (ED) patients treated for skin and soft tissue infections. For each case, we recorded the presence or absence of select criteria and whether the patient needed high-level care, defined as ICU admission, operating room surgical intervention, or death as the primary outcome. We applied recursive partitioning to identify the principal criteria associated with high-level care.

RESULTS:
We identified 2,923 patients, including 84 experiencing high-level events. Recursive partitioning identified 6 variables associated with high-level outcomes: abnormal computed tomography, magnetic resonance imaging, or ultrasonographic imaging result; systemic inflammatory response syndrome; history of diabetes; previous infection at the same location; older than 65 years; and an infection involving the hand. One or more of these variables were present in all 84 patients requiring high-level care.

CONCLUSION:
A limited number of simple clinical characteristics appear to be able to identify skin and soft tissue infection patients who require high-level inpatient services. Further research is needed to determine whether patients who do not exhibit these criteria can be safely discharged from the ED.

11. Physician Prescribing Performance Comparisons Reduces Opioids Prescribing

A. Reduction of opioid prescribing through the sharing of individual physician opioid prescribing practices.

Boyle KL, et al. Am J Emerg Med. 2019;37(1):118-122.

BACKGROUND:
Drug overdoses are the most common cause of accidental death in the United States, with the majority being attributed to opioids. High per capita opioid prescribing is correlated with higher rates of opioid abuse and death. We aimed to determine the impact of sharing individual prescribing data on the rates of opioid prescriptions written for patients discharged from the emergency department (ED).

METHODS:
This was a pre-post intervention at a single community ED. We compared opioid prescriptions written on patient discharge before and after an intervention consisting of sharing individual and comparison prescribing data. Clinicians at or over one standard deviation above the mean were notified via standard template electronic communication.

RESULTS:
For each period, we reported the median number of monthly prescriptions written by each clinician, accounting for the total number of patient discharges. The pre-intervention median was 12.5 prescriptions per 100 patient discharges (IQR 10-19) compared to 9 (IQR 6-11) in the post-intervention period (p  less than 0.001). This represents a 28% reduction in the overall rate of opioid prescriptions written per patient discharged. Using interrupted time series analysis for monthly rates, this was associated with a reduction in opioid prescriptions, showing a decrease of almost 9 prescriptions for every 100 discharges over the 6 months of the study (p = 0.032).

CONCLUSION:
Our study demonstrates the sharing of individual opioid prescribing data was associated with a reduction in opioid prescribing at a single institution.

B. Quality Improvement Initiative to Decrease Variability of Emergency Physician Opioid Analgesic Prescribing.

Burton JH, et al. West J Emerg Med. 2016 May;17(3):258-63.

INTRODUCTION:
Addressing pain is a crucial aspect of emergency medicine. Prescription opioids are commonly prescribed for moderate to severe pain in the emergency department (ED); unfortunately, prescribing practices are variable. High variability of opioid prescribing decisions suggests a lack of consensus and an opportunity to improve care. This quality improvement (QI) initiative aimed to reduce variability in ED opioid analgesic prescribing.

METHODS:
We evaluated the impact of a three-part QI initiative on ED opioid prescribing by physicians at seven sites. Stage 1: Retrospective baseline period (nine months). Stage 2: Physicians were informed that opioid prescribing information would be prospectively collected and feedback on their prescribing and that of the group would be shared at the end of the stage (three months). Stage 3: After physicians received their individual opioid prescribing data with blinded comparison to the group means (from Stage 2) they were informed that individual prescribing data would be unblinded and shared with the group after three months. The primary outcome was variability of the standard error of the mean and standard deviation of the opioid prescribing rate (defined as number of patients discharged with an opioid divided by total number of discharges for each provider). Secondary observations included mean quantity of pills per opioid prescription, and overall frequency of opioid prescribing.

RESULTS:
The study group included 47 physicians with 149,884 ED patient encounters. The variability in prescribing decreased through each stage of the initiative as represented by the distributions for the opioid prescribing rate: Stage 1 mean 20%; Stage 2 mean 13% (46% reduction, p less than 0.01), and Stage 3 mean 8% (60% reduction, p less than 0.01). The mean quantity of pills prescribed per prescription was 16 pills in Stage 1, 14 pills in Stage 2 (18% reduction, p less than 0.01), and 13 pills in Stage 3 (18% reduction, p less than 0.01). The group mean prescribing rate also decreased through each stage: 20% in Stage 1, 13% in Stage 2 (46% reduction, p less than 0.01), and 8% in Stage 3 (60% reduction, p less than 0.01).

CONCLUSION:
ED physician opioid prescribing variability can be decreased through the systematic application of sharing of peer prescribing rates and prescriber specific normative feedback.


12. Nonanesthetic Effects of Ketamine: A Review Article.

Eldufani J, et al. Am J Med. 2018 Dec;131(12):1418-1424.

Ketamine, considered a dissociative anesthetic medication, has a variety of pharmacologic effects including sedation, analgesia, bronchodilation, and nervous system stimulation. Ketamine appears to have particular mechanisms that are potentially involved during analgesic induction, including enhancing of descending inhibition and anti-inflammatory effects. This drug has potential in clinical practice for the management of chronic pain, cognitive function, depression, acute brain injury, and disorders of the immune system.


13. Bleeding Research

A. New Score Predicts Low-Risk Lower GI Bleeding

The SHA2PE score accurately identified patients who did not require intervention.

Hreinsson JP et al. The SHA2PE score: a new score for lower gastrointestinal bleeding that predicts low-risk of hospital-based intervention. Scand J Gastroenterol 2018 Nov 20

OBJECTIVES:
Lower gastrointestinal bleeding (LGIB) risk scores have mainly focused on identifying high-risk patients. A risk score aimed at predicting which patients will not require hospital-based intervention may reduce unnecessary hospital admissions. The aim of the current study was to develop such a risk score.

MATERIAL AND METHODS:
A retrospective, population-based study that included patients presenting to the emergency room (ER) with LGIB from 2010 to 2013. Hospital-based intervention was defined as blood transfusion, endoscopic hemostasis, arterial embolization or surgery. The study cohort was split into train (70%) and test (30%) data. Train data were used to produce a multiple logistic regression model and a risk score that was validated on the test data.

RESULTS:
Overall, 581 patients presented 625 times to the ER, mean age 61 (±22), males 49%. Of train data patients, 72% did not require hospital-based intervention. Independent predictors of low-risk patients (did not require hospital-based intervention) were systolic pressure ≥100mmHg (Odds ratio [OR] 4.9), hemoglobin greater than 12g/dL (OR 103), hemoglobin 10.5-12.0g/dL (OR 19), no antiplatelets (OR 3.7), no anticoagulants (OR 2.2), pulse ≤100 (OR 2.9), and visible bleeding in the ER (OR 3.8). When validating the score on the test data, only 2% were wrongly predicted to be low-risk, the negative predictive value was 96% and the area under curve was 0.83.

CONCLUSIONS:
A new risk score has been developed for LGIB that may help identify low-risk patients in the ER that can be managed in an outpatient setting, thereby lowering unnecessary hospital admissions.

B. Comparison of the National Early Warning Score+Lactate score with the pre-endoscopic Rockall, Glasgow-Blatchford, and AIMS65 scores in patients with upper GIB

Kim D, et al. Clin Exp Emerg Med 2018; 5(4): 219-229.

What is already known
Recently, the serum lactate level has been shown to be a significant predictor of mortality in upper gastrointestinal bleeding (UGIB). However, the traditional risk scores that are currently used for UGIB do not contain the serum lactate level as one of their components.

What is new in the current study
The National Early Warning Score+Lactate score showed better discriminative performance than the pre-endoscopic Rockall score and comparable discriminative performance to the Glasgow-Blatchford score and albumin, international normalized ratio, altered mental status, systolic blood pressure, age older than 65 years score for the composite of in-hospital death, intensive care unit admission, and requiring red blood cell transfusion of ≥5 packs within 24 hours.

Objective
We compared the predictive value of the National Early Warning Score+Lactate (NEWS+L) score with those of other parameters such as the pre-endoscopic Rockall score (PERS), Glasgow-Blatchford score (GBS), and albumin, international normalized ratio, altered mental status, systolic blood pressure, age older than 65 years score (AIMS65) among patients with upper gastrointestinal bleeding (UGIB).

Methods
We conducted a retrospective study of patients with UGIB during 2 consecutive years. The primary outcome was the composite of in-hospital death, intensive care unit admission, and the need for ≥5 packs of red blood cell transfusion within 24 hours.

Results
Among 530 included patients, the composite outcome occurred in 59 patients (19 in-hospital deaths, 13 intensive care unit admissions, and 40 transfusions of ≥5 packs of red blood cells within 24 hours). The area under the receiver operating characteristic curve of the NEWS+L score for the composite outcome was 0.76 (95% confidence interval, 0.70 to 0.82), which demonstrated a significant difference compared to PERS (0.66, 0.59–0.73, P=0.004), but not to GBS (0.70, 0.64–0.77, P=0.141) and AIMS65 (0.76, 0.70–0.83, P=0.999). The sensitivities of NEWS+L scores of 3 (n=34, 6.4%), 4 (n=92, 17.4%), and 5 (n=171, 32.3%) were 100%, 98.3%, and 96.6%, respectively, while the sensitivity of an AIMS65 score of 0 (n=159, 30.0%) was 91.5%.

Conclusion
The NEWS+L score showed better discriminative performance than the PERS and comparable discriminative performance to the GBS and AIMS65. The NEWS+L score may be used to identify low-risk patients among patients with UGIB.


C. PPIs may reduce OAC-induced UGI Bleeding by One-third

Ray WA, et al. Association of Oral Anticoagulants and Proton Pump Inhibitor Cotherapy With Hospitalization for Upper Gastrointestinal Tract Bleeding. JAMA. 2018;320(21):2221-2230.

Key Points
Question  Are anticoagulant drug choice and proton pump inhibitor (PPI) cotherapy associated with the risk of upper gastrointestinal tract bleeding in Medicare beneficiaries?

Findings  During 754 389 person-years of anticoagulation treatment with apixaban, dabigatran, rivaroxaban, and warfarin, the risk of hospitalization for upper gastrointestinal tract bleeding was highest for rivaroxaban. The use of PPI cotherapy (264 447 person-years) was associated with a significantly lower overall risk of gastrointestinal bleeding for all anticoagulants (incidence rate ratio, 0.66).

Meaning  Drug choice and PPI cotherapy may be important during oral anticoagulant treatment, particularly for patients with elevated risk of gastrointestinal bleeding.

Abstract
Importance  Anticoagulant choice and proton pump inhibitor (PPI) cotherapy could affect the risk of upper gastrointestinal tract bleeding, a frequent and potentially serious complication of oral anticoagulant treatment.

Objectives  To compare the incidence of hospitalization for upper gastrointestinal tract bleeding in patients using individual anticoagulants with and without PPI cotherapy, and to determine variation according to underlying gastrointestinal bleeding risk.

Design, Setting, and Participants  Retrospective cohort study in Medicare beneficiaries between January 1, 2011, and September 30, 2015.

Exposures  Apixaban, dabigatran, rivaroxaban, or warfarin with or without PPI cotherapy.

Main Outcomes and Measures  Hospitalizations for upper gastrointestinal tract bleeding: adjusted incidence and risk difference (RD) per 10 000 person-years of anticoagulant treatment, incidence rate ratios (IRRs).

Results  There were 1 643 123 patients with 1 713 183 new episodes of oral anticoagulant treatment included in the cohort (mean [SD] age, 76.4 [2.4] years, 651 427 person-years of follow-up [56.1%] were for women, and the indication was atrial fibrillation for 870 330 person-years [74.9%]). During 754 389 treatment person-years without PPI cotherapy, the adjusted incidence of hospitalization for upper gastrointestinal tract bleeding (n = 7119) was 115 per 10 000 person-years (95% CI, 112-118). The incidence for rivaroxaban (n = 1278) was 144 per 10 000 person-years (95% CI, 136-152), which was significantly greater than the incidence of hospitalizations for apixaban (n = 279; 73 per 10 000 person-years; IRR, 1.97 [95% CI, 1.73-2.25]; RD, 70.9 [95% CI, 59.1-82.7]), dabigatran (n = 629; 120 per 10 000 person-years; IRR, 1.19 [95% CI, 1.08-1.32]; RD, 23.4 [95% CI, 10.6-36.2]), and warfarin (n = 4933; 113 per 10 000 person-years; IRR, 1.27 [95% CI, 1.19-1.35]; RD, 30.4 [95% CI, 20.3-40.6]). The incidence for apixaban was significantly lower than that for dabigatran (IRR, 0.61 [95% CI, 0.52-0.70]; RD, −47.5 [95% CI,−60.6 to −34.3]) and warfarin (IRR, 0.64 [95% CI, 0.57-0.73]; RD, −40.5 [95% CI, −50.0 to −31.0]). When anticoagulant treatment with PPI cotherapy (264 447 person-years; 76 per 10 000 person-years) was compared with treatment without PPI cotherapy, risk of upper gastrointestinal tract bleeding hospitalizations (n = 2245) was lower overall (IRR, 0.66 [95% CI, 0.62-0.69]) and for apixaban (IRR, 0.66 [95% CI, 0.52-0.85]; RD, −24 [95% CI, −38 to −11]), dabigatran (IRR, 0.49 [95% CI, 0.41-0.59]; RD, −61.1 [95% CI, −74.8 to −47.4]), rivaroxaban (IRR, 0.75 [95% CI, 0.68-0.84]; RD, −35.5 [95% CI, −48.6 to −22.4]), and warfarin (IRR, 0.65 [95% CI, 0.62-0.69]; RD, −39.3 [95% CI, −44.5 to −34.2]).

Conclusions and Relevance  Among patients initiating oral anticoagulant treatment, incidence of hospitalization for upper gastrointestinal tract bleeding was the highest in patients prescribed rivaroxaban, and the lowest for patients prescribed apixaban. For each anticoagulant, the incidence of hospitalization for upper gastrointestinal tract bleeding was lower among patients who were receiving PPI cotherapy. These findings may inform assessment of risks and benefits when choosing anticoagulant agents.

D. Effect of low and moderate dose FEIBA to reverse major bleeding in patients on direct oral anticoagulants.

Dager WE, et al. Thromb Res. 2018 Nov 16;173:71-76.

OBJECTIVE:
Management of acute, major or life threatening bleeding in the presence of direct acting oral anticoagulants (DOAC) is unclear. In the absence of a specific antidote, or in situations where there is a need for adjunctive therapy, the ideal prothrombin complex concentrate and dose is unclear. The goal of our study was to evaluate the outcomes of our reduced dosing strategy with FEIBA in patients experiencing a DOAC-related bleeding event.

DESIGN:
Retrospective analysis of patients treated with FEIBA for a DOAC-related bleeding event.

SETTING:
Academic medical center PATIENTS: Consecutive patients between May 2011 and April 2017 receiving FEIBA for a DOAC-related bleed INTERVENTIONS: None MEASUREMENTS & MAIN RESULTS: Of the 64 patients included in this analysis, 38 patients received low dose FEIBA (mean 10.0 ± 3.6 units/kg) and 26 received moderate dose (mean 24.3 ± 2.1 units/kg) FEIBA; an additional dose was requested in 6 patients. Six dabigatran patients received idarucizumab. 30 day event rates included 5 thromboembolic events (8%) and 9 (14%) patients expired. Follow-up CT-imaging for ICH, endoscopy/colonoscopy, or interventional radiology exams did not reveal any clinically concerning active bleeding or hematoma expansion except in 2 ICH patients with slight expansion between imaging sessions.

CONCLUSIONS:
Low (less than 20 units/kg) to moderate (20-30 units/kg) doses of FEIBA, with the option for a repeat dose, may be an effective management strategy for obtaining hemostasis in DOAC-related major bleeding events.

14. Associations of ICU Capacity Strain with Disposition and Outcomes of Patients with Sepsis Presenting to the ED

Anesi GL, et al. Ann Am Thorac Soc. 2018 Nov;15(11):1328-1335.

RATIONALE:
Intensive care unit (ICU) capacity strain refers to the potential limits placed on an ICU's ability to provide high-quality care for all patients who may need it at a given time. Few studies have investigated how fluctuations in ICU capacity strain might influence care outside the ICU.

OBJECTIVES:
To determine whether ICU capacity strain is associated with initial level of inpatient care and outcomes for emergency department (ED) patients hospitalized for sepsis.

METHODS:
We performed a retrospective cohort study of patients with sepsis admitted from the ED to a medical ward or ICU at three hospitals within the University of Pennsylvania Health System between 2012 and 2015. Patients were excluded if they required life support therapies, defined as invasive or noninvasive ventilatory support or vasopressors, at the time of admission. The exposures were four measures of ICU capacity strain at the time of the ED disposition decision: ICU occupancy, ICU turnover, ICU census acuity, and ward occupancy. The primary outcome was the decision to admit to a ward or to an ICU. Secondary analyses assessed the association of ICU capacity strain with in-hospital outcomes, including mortality.

RESULTS:
Among 77,142 hospital admissions from the ED, 3,067 patients met the study's eligibility criteria. The ICU capacity strain metrics varied between and within study hospitals over time. In unadjusted analyses, ICU occupancy, ICU turnover, ICU census acuity, and ward occupancy were all negatively associated with ICU admission. In the fully adjusted model including patient-level covariates, only ICU occupancy remained associated with ICU admission (odds ratio, 0.87; 95% confidence interval, 0.79-0.96; P = 0.005), such that a 10% increase in ICU occupancy (e.g., one additional patient in a 10-bed ICU) was associated with a 13% decrease in the odds of ICU admission. Among the subset of patients admitted initially from the ED to a medical ward, ICU occupancy at the time of admission was associated with increased odds of hospital mortality (odds ratio, 1.61; 95% confidence interval, 1.21-2.14; P = 0.001).

CONCLUSIONS:
The odds that patients in the ED with sepsis who do not require life support therapies will be admitted to the ICU are reduced when those ICUs experience high occupancy but not high levels of other previously explored measures of capacity strain. Patients with sepsis admitted to the wards during times of high ICU occupancy had increased odds of hospital mortality.

15. Online physician ratings fail to predict actual performance on measures of quality, value, and peer review.

Daskivich TJ, et al. J Am Med Inform Assoc. 2018 Apr 1;25(4):401-407.

OBJECTIVE:
Patients use online consumer ratings to identify high-performing physicians, but it is unclear if ratings are valid measures of clinical performance. We sought to determine whether online ratings of specialist physicians from 5 platforms predict quality of care, value of care, and peer-assessed physician performance.

MATERIALS AND METHODS:
We conducted an observational study of 78 physicians representing 8 medical and surgical specialties. We assessed the association of consumer ratings with specialty-specific performance scores (metrics including adherence to Choosing Wisely measures, 30-day readmissions, length of stay, and adjusted cost of care), primary care physician peer-review scores, and administrator peer-review scores.

RESULTS:
Across ratings platforms, multivariable models showed no significant association between mean consumer ratings and specialty-specific performance scores (β-coefficient range, -0.04, 0.04), primary care physician scores (β-coefficient range, -0.01, 0.3), and administrator scores (β-coefficient range, -0.2, 0.1). There was no association between ratings and score subdomains addressing quality or value-based care. Among physicians in the lowest quartile of specialty-specific performance scores, only 5%-32% had consumer ratings in the lowest quartile across platforms. Ratings were consistent across platforms; a physician's score on one platform significantly predicted his/her score on another in 5 of 10 comparisons.

DISCUSSION:
Online ratings of specialist physicians do not predict objective measures of quality of care or peer assessment of clinical performance. Scores are consistent across platforms, suggesting that they jointly measure a latent construct that is unrelated to performance.

CONCLUSION:
Online consumer ratings should not be used in isolation to select physicians, given their poor association with clinical performance.

16. Critical EMS Research

A. EMS Use Among Patients Receiving Involuntary Psychiatric Holds and the Safety of an Out-of-Hospital Screening Protocol to “Medically Clear” Psychiatric Emergencies in the Field, 2011 to 2016

Trivedi TK, et al. Ann Emerg Med. 2019;73(1):42-51.

STUDY OBJECTIVE:
Patients with acute psychiatric emergencies who receive an involuntary hold often spend hours in the emergency department (ED) because of a deficit in inpatient psychiatric beds. One solution to address the lack of prompt psychiatric evaluation in the ED has been to establish regional stand-alone psychiatric emergency services. However, patients receiving involuntary holds still need to be screened and evaluated to ensure that their behavior is not caused by an underlying and life-threatening nonpsychiatric illness. Although traditional regional emergency medical services (EMS) systems depend on the medical ED for this function, a field-screening protocol can allow EMS to directly transport a substantial portion of patients to a stand-alone psychiatric emergency service. The purpose of this investigation is to describe overall EMS use for patients receiving involuntary holds, compare patients receiving involuntary holds with all EMS patients, and evaluate the safety of field medical clearance of an established field-screening protocol in Alameda County, CA.

METHODS:
We obtained data for all EMS encounters between November 1, 2011, and November 1, 2016, using Alameda County's standardized data set. After unique patient identification, we describe the data at the patient level and at the encounter level. At the patient level, we compare "involuntary hold patients" (≥1 involuntary hold during the study period) with those who were "never held." Additionally, we assess the safety of out-of-hospital medical clearance by calculating the rate of failed diversion, defined as retransport of a patient to a medical ED within 12 hours of transport to the psychiatric emergency services by EMS.

RESULTS:
Of the 541,731 total EMS encounters in Alameda County during the study period, 10% (N=53,887) were identified as involuntary hold encounters. Of these involuntary hold patient encounters, 41% (N=22,074) resulted in direct transport of the patient to the stand-alone psychiatric emergency service for evaluation; 0.3% (N=60) failed diversion and required retransport within 12 hours. At the patient level, Alameda County EMS encountered 257,625 unique patients, and 10% (N=26,283) had at least one encounter for an involuntary hold during the study period. These "involuntary hold patients" were substantially younger, more likely to be men, and less likely to be insured. Additionally, they had higher overall EMS use: "involuntary hold patients" accounted for 24% of all encounters (N=128,003); 53,887 of these encounters were for involuntary holds, whereas an additional 74,116 were for other reasons. Similarly, 4% of "involuntary hold patients" had 20 or more encounters, whereas only 0.4% of "never held" patients were in this category. Last, the 7% of "involuntary hold patients" (N=1,907) who received greater than or equal to 5 involuntary holds during the study period accounted for 39% of all involuntary holds and 9% of all EMS encounters.

CONCLUSION:
Ten percent of all EMS encounters were for involuntary psychiatric holds. With an EMS-directed screening protocol, 41% of all such patient encounters resulted in direct transport of the patient to the psychiatric emergency service, bypassing medical clearance in the ED. Overall, only 0.3% of these patients required retransport to a medical ED within 12 hours of arrival to psychiatric emergency services. We found that 24% of all EMS encounters in Alameda County were attributable to "involuntary hold patients," reinforcing the importance of the effects of mental illness on EMS use.


B. Long-Term Outcomes of Out-of-Hospital Cardiac Arrest Care Improved at Regionalized Centers

Elmer J, et al. Ann Emerg Med. 2019;73(1):29-39.

STUDY OBJECTIVE:
It is unknown whether regionalization of postarrest care by interfacility transfer to cardiac arrest receiving centers reduces mortality. We seek to evaluate whether treatment at a cardiac arrest receiving center, whether by direct transport or early interfacility transfer, is independently associated with long-term outcome.

METHODS:
We performed a retrospective cohort study including adults resuscitated from out-of-hospital cardiac arrest in southwestern Pennsylvania and neighboring Ohio, West Virginia, and Maryland, which includes approximately 5.7 million residents in urban, suburban, and rural counties. Patients were treated by 1 of 78 ground emergency medical services agencies or 2 air medical transport agencies between January 1, 2010, and November 30, 2014. Our primary exposures of interest were interfacility transfer to a cardiac arrest receiving center within 24 hours of arrest or any treatment at a cardiac arrest receiving center regardless of transfer status. Our primary outcome was vital status, assessed through December 31, 2014, with National Death Index records. We used unadjusted and adjusted survival analyses to test the independent association of cardiac arrest receiving center care, whether through direct or interfacility transport, on mortality.

RESULTS:
Overall, 5,217 cases were observed for 3,629 person-years, with 3,865 total deaths. Most patients (82%) were treated at 42 non-cardiac arrest receiving centers with median annual volume of 17 cases (interquartile range 1 to 53 cases per center annually), whereas 18% were cared for at cardiac arrest receiving centers receiving at least 1 interfacility transfer per month. In adjusted models, treatment at a cardiac arrest receiving center was independently associated with reduced hazard of death compared with treatment at a non-cardiac arrest receiving center (adjusted hazard ratio 0.84; 95% confidence interval 0.74 to 0.94). These effects were unchanged when analysis was restricted to patients brought from the scene to the treating hospital. No other hospital characteristic, including total out-of-hospital cardiac arrest patient volume and cardiac catheterization capabilities, independently predicted outcome.

CONCLUSION:
Both early interfacility transfer to a cardiac arrest receiving center and direct transport to a cardiac arrest receiving center from the scene are independently associated with reduced mortality.

17. Misdiagnosis of Cerebral Vein Thrombosis in the ED

Liberman AL, et al. Stroke. 2018;49(6):1504-1506.

BACKGROUND AND PURPOSE:
Rates of cerebral venous thrombosis (CVT) misdiagnosis in the emergency department and outcomes associated with misdiagnosis have been underexplored.

METHODS:
Using administrative data, we identified adults with CVT at New York, California, and Florida hospitals from 2005 to 2013. Our primary outcome was probable misdiagnosis of CVT, defined as a treat-and-release emergency department visit for headache or seizure within 14 days before CVT. In addition, logistic regression was used to compare rates of clinical outcomes in patients with and without probable CVT misdiagnosis. We performed a confirmatory study at 2 tertiary care centers.

RESULTS:
We identified 5966 patients with CVT in whom 216 (3.6%; 95% confidence interval [CI], 1.1%-4.1%) had a probable misdiagnosis of CVT. After adjusting for demographics, risk factors for CVT, and the Elixhauser comorbidity index, probable CVT misdiagnosis was not associated with in-hospital mortality (odds ratio, 0.14; 95% CI, 0.02-1.05), intracerebral hemorrhage (odds ratio, 0.97; 95% CI, 0.57-1.65), or unfavorable discharge disposition (odds ratio, 0.90; 95% CI, 0.61-1.32); a longer length of hospital stay was seen among misdiagnosed patients with CVT (odds ratio, 1.62; 95% CI, 1.04-2.50). In our confirmatory cohort, probable CVT misdiagnosis occurred in 8 of 134 patients with CVT (6.0%; 95% CI, 2.6%-11.4%).

CONCLUSIONS:
In a large, heterogeneous multistate cohort, probable misdiagnosis of CVT occurred in 1 of 30 patients but was not associated with the adverse clinical outcomes included in our study.

18. Helpful Reviews from Ann Emerg Med

A. Should Adults With Mild Head Injury Who Are Receiving Direct Oral Anticoagulants Undergo CT Scanning? A Systematic Review

Conclusion
There are limited data available to characterize the risk of adverse outcome in patients receiving direct oral anticoagulants after mild traumatic brain injury. A sufficiently powered prospective cohort study is required to validly define this risk, identify clinical features predictive of adverse outcome, and inform future head injury guidelines.


But until better studies roll in, I’m inclined to get the scan.

B. What Physiologic Parameters Are Indicative of Severe Injury in Trauma?

Take-Home Message
Pulse rate, systolic blood pressure, shock index, respiratory rate, and lactate demonstrate poor sensitivity but high specificity for predicting severe injury among trauma patients. No parameter in isolation is able to adequately predict the risk of severe injury.


19. Pain Control Research

A. Gentle stroking may curb pain in babies

UK researchers found that infants who were gently stroked at an optimal speed of 3 cm per second during blood tests had 40% reduced pain-related brain activity, compared with controls who weren't stroked. The findings in Current Biology may help explain the benefits of massages, kangaroo care and other touch-based practices for babies, said researcher Rebeccah Slater.



B. Opioids for Chronic Noncancer Pain: A Systematic Review and Meta-analysis.

Busse JW, et al. JAMA. 2018 Dec 18;320(23):2448-2460.

IMPORTANCE:
Harms and benefits of opioids for chronic noncancer pain remain unclear.

OBJECTIVE:
To systematically review randomized clinical trials (RCTs) of opioids for chronic noncancer pain.

DATA SOURCES AND STUDY SELECTION:
The databases of CENTRAL, CINAHL, EMBASE, MEDLINE, AMED, and PsycINFO were searched from inception to April 2018 for RCTs of opioids for chronic noncancer pain vs any nonopioid control.

DATA EXTRACTION AND SYNTHESIS:
Paired reviewers independently extracted data. The analyses used random-effects models and the Grading of Recommendations Assessment, Development and Evaluation to rate the quality of the evidence.

MAIN OUTCOMES AND MEASURES:
The primary outcomes were pain intensity (score range, 0-10 cm on a visual analog scale for pain; lower is better and the minimally important difference [MID] is 1 cm), physical functioning (score range, 0-100 points on the 36-item Short Form physical component score [SF-36 PCS]; higher is better and the MID is 5 points), and incidence of vomiting.

RESULTS:
Ninety-six RCTs including 26 169 participants (61% female; median age, 58 years [interquartile range, 51-61 years]) were included. Of the included studies, there were 25 trials of neuropathic pain, 32 trials of nociceptive pain, 33 trials of central sensitization (pain present in the absence of tissue damage), and 6 trials of mixed types of pain. Compared with placebo, opioid use was associated with reduced pain (weighted mean difference [WMD], -0.69 cm [95% CI, -0.82 to -0.56 cm] on a 10-cm visual analog scale for pain; modeled risk difference for achieving the MID, 11.9% [95% CI, 9.7% to 14.1%]), improved physical functioning (WMD, 2.04 points [95% CI, 1.41 to 2.68 points] on the 100-point SF-36 PCS; modeled risk difference for achieving the MID, 8.5% [95% CI, 5.9% to 11.2%]), and increased vomiting (5.9% with opioids vs 2.3% with placebo for trials that excluded patients with adverse events during a run-in period). Low- to moderate-quality evidence suggested similar associations of opioids with improvements in pain and physical functioning compared with nonsteroidal anti-inflammatory drugs (pain: WMD, -0.60 cm [95% CI, -1.54 to 0.34 cm]; physical functioning: WMD, -0.90 points [95% CI, -2.69 to 0.89 points]), tricyclic antidepressants (pain: WMD, -0.13 cm [95% CI, -0.99 to 0.74 cm]; physical functioning: WMD, -5.31 points [95% CI, -13.77 to 3.14 points]), and anticonvulsants (pain: WMD, -0.90 cm [95% CI, -1.65 to -0.14 cm]; physical functioning: WMD, 0.45 points [95% CI, -5.77 to 6.66 points]).

CONCLUSIONS AND RELEVANCE:
In this meta-analysis of RCTs of patients with chronic noncancer pain, evidence from high-quality studies showed that opioid use was associated with statistically significant but small improvements in pain and physical functioning, and increased risk of vomiting compared with placebo. Comparisons of opioids with nonopioid alternatives suggested that the benefit for pain and functioning may be similar, although the evidence was from studies of only low to moderate quality.

20. Night shift preparation, performance, and perception: are there differences between emergency medicine nurses, residents, and faculty?

Richards JR, et al. Clin Exp Emerg Med. 2018;5(4): 40-248.

OBJECTIVE:
Determine differences between faculty, residents, and nurses regarding night shift preparation, performance, recovery, and perception of emotional and physical health effects.

METHODS:
Survey study performed at an urban university medical center emergency department with an accredited residency program in emergency medicine.

RESULTS:
Forty-seven faculty, 37 residents, and 90 nurses completed the survey. There was no difference in use of physical sleep aids between groups, except nurses utilized blackout curtains more (69%) than residents (60%) and faculty (45%). Bedroom temperature preference was similar. The routine use of pharmacologic sleep aids differed: nurses and residents (both 38%) compared to faculty (13%). Residents routinely used melatonin more (79%) than did faculty (33%) and nurses (38%). Faculty preferred not to eat (45%), whereas residents (24%) preferred a full meal. The majority (greater than 72%) in all groups drank coffee before their night shift and reported feeling tired despite their routine, with 4:00 a.m. as median nadir. Faculty reported a higher rate (41%) of falling asleep while driving compared to residents (14%) and nurses (32%), but the accident rate (3% to 6%) did not differ significantly. All had similar opinions regarding night shift-associated health effects. However, faculty reported lower level of satisfaction working night shifts, whereas nurses agreed less than the other groups regarding increased risk of drug and alcohol dependence.

CONCLUSION:
Faculty, residents, and nurses shared many characteristics. Faculty tended to not use pharmacologic sleep aids, not eat before their shift, fall asleep at a higher rate while driving home, and enjoy night shift work less.

21. Directing Low-risk Patients Safely to Appropriate non-ED Venues

A. Tele-triage outcomes for patients with chest pain: comparing physicians and registered nurses.

Sax DR, et al.  Health Affairs. 2018;37(12):1997-2004.

We took advantage of a change in protocol in an integrated delivery system’s telephone consultation service—routing callers complaining of chest pain to physicians instead of registered nurses, whenever feasible—to explore whether tele-triage outcomes differed by staffing type.

Comparing outcomes of 11,315 physician-directed calls to those of an equal number of nurse-directed calls in 2013, we found that the physician-directed calls were briefer (eight minutes versus thirteen minutes), produced fewer ED referrals (10 percent versus 16 percent), and resulted in higher patient adherence to the providers’ site-of-care recommendation (86 percent versus 82 percent). Mortality rates at seven days were low for both physician- and nurse-directed calls (0.1 percent). We suspect that providers’ immediate access to callers’ comprehensive electronic health records and patients’ rapid access to outpatient care likely contributed to the program’s success.

Our findings suggest that tele-triage can be used to safely and effectively manage an emergent complaint, and that physicians’ expertise may bring additional efficiency to the process.


B. No clear evidence that diverting patients from EDs curbs overcrowding

November 27, 2018, British Medical Journal

There's no clear evidence that diverting patients, who are not seriously ill, away from emergency departments, in a bid to curb overcrowding, is either safe or effective, reveals research published online in Emergency Medicine Journal.

Given the considerable costs of providing alternative sources of care, there is remarkably little good quality evidence to back this approach, conclude the researchers. Redirecting low need patients from emergency care departments to alternative sources of care, has been proposed as a potential solution to tackling the overcrowding that often occurs in these facilities.

But it isn't clear whether this strategy actually works or is safe. The researchers therefore systematically reviewed and pooled the data from 15 relevant studies, evaluating the impact of redirecting patients to alternative sources of care before reaching, or once in, an emergency care department.

No strong evidence emerged to either back or refute the safety and effectiveness of this strategy, the data analysis showed. What's more, the proportion of patients suitable for diversion was relatively low and a considerable proportion of those who were suitable didn't want to use alternative sources of care either.

Redirecting patients to alternative sources of care was twice as common among those who had already reached an emergency care department. But compared with those who weren't redirected, doing this before the patient reached hospital didn't cut the proportion transferred to emergency care. Nor did it stop them subsequently using emergency care services: their patterns of use didn't differ from those of patients who weren't redirected.

While only three studies looked at the costs involved, none found any difference in total healthcare spend between patients who were diverted away from emergency care departments and those who weren't.

The overall quality of the published evidence was not particularly good. This included varying definitions of low need; limited information on the outcomes of patients given standard care; the numbers of patients willing and able to accept alternative sources of care; or the costs involved.

"Despite the clear resource implications for implementing [emergency department] diversion strategies, including training and hiring additional staff, costs of implementing the diversion strategies were infrequently reported," they write.

All this makes it difficult to draw definitive conclusions, they caution, concluding: "At this time there is insufficient evidence to recommend the implementation of diversion protocols as effective and safe strategies to address emergency department overcrowding."

And in a linked podcast in discussion with the journal's editor, Professor Ellen Weber, lead author, Dr. Brian Rowe, University of Alberta, isn't convinced 'the juice is worth the squeeze.'
"I am not sure the efforts involved in doing diversion are really worth all the costs, time, and surveillance," he says. And not all emergency department patients are the same, although the diversionary strategies to date tend to assume that they are, he says.

Surveys in Canada indicate that patients have often tried many other options before coming to an emergency department, or that they are there because the health system has failed them, he suggests. What's more, he adds, patients like the 'one-stop shop' service provided by hospitals, and younger patients often don't register with a family doctor, leaving them with few other options.

22. FDA warns fluoroquinolones can cause fatal aortic dissection

Drugs commonly used to treat upper respiratory infection, urinary tract infections should not be prescribed to patients already at risk.

Maggie Fox. NBC News. Dec. 20, 2018

Certain antibiotics can cause painful and sometimes fatal damage to the body’s main artery, the Food and Drug Administration said Thursday.

Fluoroquinolone antibiotics might raise the risk of an aortic dissection, and people who are already at risk should be cautious about taking those antibiotics, the FDA said.

“A U.S. Food and Drug Administration (FDA) review found that fluoroquinolone antibiotics can increase the occurrence of rare but serious events of ruptures or tears in the main artery of the body, called the aorta. These tears, called aortic dissections, or ruptures of an aortic aneurysm can lead to dangerous bleeding or even death,” the FDA said in a statement.

“Fluoroquinolones should not be used in patients at increased risk unless there are no other treatment options available. People at increased risk include those with a history of blockages or aneurysms (abnormal bulges) of the aorta or other blood vessels, high blood pressure, certain genetic disorders that involve blood vessel changes, and the elderly.”

The FDA said the new risk guidance will be added to the labels and prescribing information of fluoroquinolone drugs. The agency has already warned that the powerful drugs should only be used when absolutely necessary because they can cause other side effects involving tendons, muscles, joints, nerves and the central nervous system…

G. ERs can be loud, hectic and even dangerous for the elderly. Here’s how hospitals are trying to fix that.

In 2005, when physician Kevin Biese was a medical resident in Boston, a 92-year-old woman with a urinary tract infection arrived by ambulance at a hospital emergency room. Her behavior — confusion and lethargy — suggested she also was suffering from hypoactive delirium, a cognitive disorder.

She was alone, without family or friends. The doctors decided to admit her, but a bed wasn’t yet available. So she had to wait. “She spent 24 hours on a cot in the hallway,” Biese recalls. “She came in during the day on a Thursday and was still there Friday morning. I got mad.”

The emergency care system should “not allow that to happen to those who deserve the most respect in our society,” he says.

Nobody enjoys a trip to the ER. But it can be especially difficult — sometimes even dangerous — for the elderly. Many emergency health-care settings are frenzied and noisy, with glaring lights and slippery floors, often without handrails. Cots and gurneys are hard on fragile bodies. Privacy is scarce….


H. 68% of patients have at least one social determinant of health

Improving social determinants for patients can have strong positive effects on the patient's health and decreased costs for the healthcare system.

Sixty-eight percent of US patients reported challenges associated with at least one social determinant of health -- such as financial or food insecurity -- and most have not discussed the issue with their health care professional, according to a Waystar survey. Patients covered by Medicare and Medicaid were more likely than those with commercial coverage to be affected by three or more social determinants, and although patients often decline assistance, they may be more receptive to offers of help after speaking with a physician or nurse, rather than an insurer.
