A randomized controlled trial comparing the Arctic Sun to standard cooling for induction of hypothermia after cardiac arrest

CONTEXT Hypothermia improves neurological outcome for comatose survivors of out-of-hospital cardiac arrest. Use of computer controlled high surface area devices for cooling may lead to faster cooling rates and potentially improve patient outcome. OBJECTIVE To compare the effectiveness of surface cooling with the standard blankets and ice packs to the Arctic Sun, a mechanical device used for temperature management. DESIGN, SETTING, AND PATIENTS Multi-center randomized trial of hemodynamically stable comatose survivors of out-of-hospital cardiac arrest. INTERVENTION Standard post-resuscitative care inducing hypothermia using cooling blankets and ice (n=30) or the Arctic Sun (n=34). MAIN OUTCOME MEASURES The primary end point was the proportion of subjects who reached a target temperature within 4h of beginning cooling. The secondary end points were time interval to achieve target temperature (34 degrees C) and survival to 3 months. RESULTS The proportion of subjects cooled below the 34 degrees C target at 4h was 71% for the Arctic Sun group and 50% for the standard cooling group (p=0.12). The median time to target was 54 min faster for cooled patients in the Arctic Sun group than the standard cooling group (p<0.01). Survival rates with good neurological outcome were similar; 46% of Arctic Sun patients and 38% of standard patients had a cerebral performance category of 1 or 2 at 30 days (p=0.6). CONCLUSIONS While the proportion of subjects reaching target temperature within 4h was not significantly different, the Arctic Sun cooled patients to a temperature of 34 degrees C more rapidly than standard cooling blankets.

Syndromic Surveillance for Influenza in the Emergency Department–A Systematic Review

The science of surveillance is rapidly evolving due to changes in public health information and preparedness as national security issues, new information technologies and health reform. As the Emergency Department has become a much more utilized venue for acute care, it has also become a more attractive data source for disease surveillance. In recent years, influenza surveillance from the Emergency Department has increased in scope and breadth and has resulted in innovative and increasingly accepted methods of surveillance for influenza and influenza-like-illness (ILI). We undertook a systematic review of published Emergency Department-based influenza and ILI syndromic surveillance systems. A PubMed search using the keywords “syndromic”, “surveillance”, “influenza” and “emergency” was performed. Manuscripts were included in the analysis if they described (1) data from an Emergency Department (2) surveillance of influenza or ILI and (3) syndromic or clinical data. Meeting abstracts were excluded. The references of included manuscripts were examined for additional studies. A total of 38 manuscripts met the inclusion criteria, describing 24 discrete syndromic surveillance systems. Emergency Department-based influenza syndromic surveillance has been described worldwide. A wide variety of clinical data was used for surveillance, including chief complaint/presentation, preliminary or discharge diagnosis, free text analysis of the entire medical record, Google flu trends, calls to teletriage and help lines, ambulance dispatch calls, case reports of H1N1 in the media, markers of ED crowding, admission and Left Without Being Seen rates. Syndromes used to capture influenza rates were nearly always related to ILI (i.e. fever +/− a respiratory or constitutional complaint), however, other syndromes used for surveillance included fever alone, “respiratory complaint” and seizure. Two very large surveillance networks, the North American DiSTRIBuTE network and the European Triple S system have collected large-scale Emergency Department-based influenza and ILI syndromic surveillance data. Syndromic surveillance for influenza and ILI from the Emergency Department is becoming more prevalent as a measure of yearly influenza outbreaks.

Developing a Third‐year Emergency Medicine Medical Student Curriculum: A Syllabus of Content

Emergency medicine (EM) educators have published several curricular guides designed for medical student rotations and experiences. These guides primarily provided brief overviews of opportunities to incorporate EM into all 4 years of the medical student curriculum, with one specific to the fourth year. However, there are no published guidelines specific to third-year medical students rotating in EM. Given the differences between third-year and fourth-year students in terms of clinical experience, knowledge, and skills, the Clerkship Directors in Emergency Medicine (CDEM) established the Third-year EM Medical Student Curriculum Work Group to create a third-year curriculum. The work group began this process by developing consensus-based recommendations for the content of a third-year medical student EM rotation, which are presented in this syllabus.

b h i e o e a i s s 3 [Ann Emerg Med. 2013;61:86-88.] Editor’s Note: Emergency physicians must often make decisions about patient management without clear-cut data of sufficient quality to support clinical guidelines or evidence-based reviews. Topics in the Best Available Evidence section must be relevant to emergency physicians, are formally peer reviewed, and must have a sufficient literature base to draw a reasonable conclusion but not such a large literature base that a traditional ”evidence-based” review, meta-analysis, or systematic review can be performed.

Influenza Vaccination in the Emergency Department: Are Our Patients at Risk?

BACKGROUND Influenza is responsible for substantial morbidity and mortality annually. Vaccination strategies target high-risk patients. The percentage of Emergency Department (ED) patients at high risk is largely unknown. OBJECTIVES The percentage of patients at high risk for influenza was determined and compared to the United States (US) population. METHODS Medical records of a convenience sample of all patients presenting to the ED of a university-affiliated hospital in Tucson, Arizona from February 1-7, 2006 were reviewed (n = 1359). Patients were stratified as 1) at high risk for influenza or its complications, 2) health care workers (HCW), household contacts of high-risk patients, and other target populations, and (3) otherwise healthy adults. Additionally, vaccination status and prior ED utilization within that seasons vaccination period was determined. RESULTS Of all patients presenting to the ED, 41.5% were at high risk for influenza or its complications (US 30.8%, p < 0.001). Of all ED patients, 10.8% were household contacts, HCWs, or in another target group (US 42.8%, p < 0.001). Of high-risk ED patients, 43.5% had been vaccinated that season (US 47.1%, p < 0.001) and 13.7% had had at least one visit to the ED within the preceding 3 months. CONCLUSION There is a higher percentage of patients at high risk for influenza in the ED population than the general US population. The ED may be a novel location in which to effectively identify and immunize high-risk individuals. Benefits to ED vaccination may include subsequent reductions in mortality and morbidity as well as a decrease in ED utilization and hospitalization for influenza and its complications.

Correlation of the NBME Advanced Clinical Examination in EM and the National EM M4 exams

Introduction Since 2011 two online, validated exams for fourth-year emergency medicine (EM) students have been available (National EM M4 Exams). In 2013 the National Board of Medical Examiners offered the Advanced Clinical Examination in Emergency Medicine (EM-ACE). All of these exams are now in widespread use; however, there are no data on how they correlate. This study evaluated the correlation between the EM-ACE exam and the National EM M4 Exams. Methods From May 2013 to April 2014 the EM-ACE and one version of the EM M4 exam were administered sequentially to fourth-year EM students at five U.S. medical schools. Data collected included institution, gross and scaled scores and version of the EM M4 exam. We performed Pearson’s correlation and random effects linear regression. Results 303 students took the EM-ACE and versions 1 (V1) or 2 (V2) of the EM M4 exams (279 and 24, respectively). The mean percent correct for the exams were as follows: EM-ACE 74.8 (SD-8.83), V1 83.0 (SD-6.41), V2 78.5 (SD-7.70). Pearson’s correlation coefficient for the V1/EM-ACE was 0.51 (0.42 scaled) and for the V2/EM-ACE was 0.59 (0.41 scaled). The coefficient of determination for V1/EM-ACE was 0.72 and for V2/EM-ACE = 0.71 (0.86 and 0.49 for scaled scores). The R-squared values were 0.25 and 0.30 (0.18 and 0.13, scaled), respectively. There was significant cluster effect by institution. Conclusion There was moderate positive correlation of student scores on the EM-ACE exam and the National EM M4 Exams.

Analysis of the evaluative components on the Standard Letter of Recommendation (SLOR) in Emergency Medicine.

Introduction The standard letter of recommendation in emergency medicine (SLOR) was developed to standardize the evaluation of applicants, improve inter-rater reliability, and discourage grade inflation. The primary objective of this study was to describe the distribution of categorical variables on the SLOR in order to characterize scoring tendencies of writers. Methods We performed a retrospective review of all SLORs written on behalf of applicants to the three Emergency Medicine residency programs in the University of Arizona Health Network (i.e. the University Campus program, the South Campus program and the Emergency Medicine/Pediatrics combined program) in 2012. All “Qualifications for Emergency Medicine” and “Global Assessment” variables were analyzed. Results 1457 SLORs were reviewed, representing 26.7% of the total number of Electronic Residency Application Service applicants for the academic year. Letter writers were most likely to use the highest/most desirable category on “Qualifications for EM” variables (50.7%) and to use the second highest category on “Global Assessments” (43.8%). For 4-point scale variables, 91% of all responses were in one of the top two ratings. For 3-point scale variables, 94.6% were in one of the top two ratings. Overall, the lowest/least desirable ratings were used less than 2% of the time. Conclusions SLOR letter writers do not use the full spectrum of categories for each variable proportionately. Despite the attempt to discourage grade inflation, nearly all variable responses on the SLOR are in the top two categories. Writers use the lowest categories less than 2% of the time. Program Directors should consider tendencies of SLOR writers when reviewing SLORs of potential applicants to their programs.

An assessment of residents’ and fellows’ personal finance literacy: an unmet medical education need

Objectives This study aimed to assess residents’ and fellows’ knowledge of finance principles that may affect their personal financial health. Methods A cross-sectional, anonymous, web-based survey was administered to a convenience sample of residents and fellows at two academic medical centers. Respondents answered 20 questions on personal finance and 28 questions about their own financial planning, attitudes, and debt. Questions regarding satisfaction with one’s financial condition and investment-risk tolerance used a 10-point Likert scale (1=lowest, 10=highest). Of 2,010 trainees, 422 (21%) responded (median age 30 years; interquartile range, 28-33). Results The mean quiz score was 52.0% (SD = 19.1). Of 299 (71%) respondents with student loan debt, 144 (48%) owed over

25,000. Respondents’ mean satisfaction with their current personal financial condition was 4.8 (SD = 2.5) and investment-risk tolerance was 5.3 (SD = 2.3). Indebted trainees reported lower satisfaction than trainees without debt (4.4 vs. 6.2, F (1,419) = 41.57, p < .001). Knowledge was moderately correlated with investment-risk tolerance (r=0.41, p < .001), and weakly correlated with satisfaction with financial status (r=0.23, p < .001). Conclusions Residents and fellows had low financial literacy and investment-risk tolerance, high debt, and deficits in their financial preparedness. Adding personal financial education to the medical education curriculum would benefit trainees. Providing education in areas such as budgeting, estate planning, investment strategies, and retirement planning early in training can offer significant long-term benefits.
