Community-Associated Methicillin-Resistant Staphylococcus aureus

Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) has emerged over the last decade across the United States and the world, becoming a major pathogen in many types of community-acquired infections. Although most commonly associated with minor skin and soft tissue infections, such as furuncles, CA-MRSA also can cause necrotizing fasciitis, pyomyositis, osteoarticular infections, and community-acquired pneumonia. This article discusses the epidemiology, diagnosis, and management of these infections from the perspective of the emergency physician.

Attending and resident satisfaction with feedback in the emergency department

OBJECTIVES Effective feedback is critical to medical education. Little is known about emergency medicine (EM) attending and resident physician perceptions of feedback. The focus of this study was to examine perceptions of the educational feedback that attending physicians give to residents in the clinical environment of the emergency department (ED). The authors compared attending and resident satisfaction with real-time feedback and hypothesized that the two groups would report different overall satisfaction with the feedback they currently give and receive in the ED. METHODS This observational study surveyed attending and resident physicians at 17 EM residency programs through web-based surveys. The primary outcome was overall satisfaction with feedback in the ED, ranked on a 10-point scale. Additional survey items addressed specific aspects of feedback. Responses were compared using a linear generalized estimating equation (GEE) model for overall satisfaction, a logistic GEE model for dichotomized responses, and an ordinal logistic GEE model for ordinal responses. RESULTS Three hundred seventy-three of 525 (71%) attending physicians and 356 of 596 (60%) residents completed the survey. Attending physicians were more satisfied with overall feedback (mean score 5.97 vs. 5.29, p < 0.001) and with timeliness of feedback (odds ratio [OR] = 1.56, 95% confidence interval [CI] = 1.23 to 2.00; p < 0.001) than residents. Attending physicians were also more likely to rate the quality of feedback as very good or excellent for positive feedback, constructive feedback, feedback on procedures, documentation, management of ED flow, and evidence-based decision-making. Attending physicians reported time constraints as the top obstacle to giving feedback and were more likely than residents to report that feedback is usually attending initiated (OR = 7.09, 95% CI = 3.53 to 14.31; p < 0.001). CONCLUSIONS Attending physician satisfaction with the quality, timeliness, and frequency of feedback given is higher than resident physician satisfaction with feedback received. Attending and resident physicians have differing perceptions of who initiates feedback and how long it takes to provide effective feedback. Knowledge of these differences in perceptions about feedback may be used to direct future educational efforts to improve feedback in the ED.

Alternatives to the conference status quo: summary recommendations from the 2008 CORD Academic Assembly Conference Alternatives workgroup.

UNLABELLED Abstract Objective: A panel of Council of Emergency Medicine Residency Directors (CORD) members was asked to examine and make recommendations regarding the existing Accreditation Council of Graduate Medical Education (ACGME) EM Program Requirements pertaining to educational conferences, identified best practices, and recommended revisions as appropriate. METHODS Using quasi-Delphi technique, 30 emergency medicine (EM) residency program directors and faculty examined existing requirements. Findings were presented to the CORD members attending the 2008 CORD Academic Assembly, and disseminated to the broader membership through the CORD e-mail list server. RESULTS The following four ACGME EM Program Requirements were examined, and recommendations made: 1. The 5 hours/week conference requirement: For fully accredited programs in good standing, outcomes should be driving how programs allocate and mandate educational time. Maintain the 5 hours/week conference requirement for new programs, programs with provisional accreditation, programs in difficult political environs, and those with short accreditation cycles. If the program requirements must retain a minimum hours/week reference, future requirements should take into account varying program lengths (3 versus 4 years). 2. The 70% attendance requirement: Develop a new requirement that allows programs more flexibility to customize according to local resources, individual residency needs, and individual resident needs. 3. The requirement for synchronous versus asynchronous learning: Synchronous and asynchronous learning activities have advantages and disadvantages. The ideal curriculum capitalizes on the strengths of each through a deliberate mixture of each. 4. Educationally justified innovations: Transition from process-based program requirements to outcomes-based requirements. CONCLUSIONS The conference requirements that were logical and helpful years ago may not be logical or helpful now. Technologies available to educators have changed, the amount of material to cover has grown, and online on-demand education has grown even more. We believe that flexibility is needed to customize EM education to suit individual resident and individual program needs, to capitalize on regional and national resources when local resources are limited, to innovate, and to analyze and evaluate interventions with an eye toward outcomes.

Effect of an Educational Intervention on Faculty and Resident Satisfaction with Real-time Feedback in the Emergency Department

OBJECTIVES Effective real-time feedback is critical to medical education. This study tested the hypothesis that an educational intervention related to feedback would improve emergency medicine (EM) faculty and resident physician satisfaction with feedback. METHODS This was a cluster-randomized, controlled study of 15 EM residency programs in 2007-2008. An educational intervention was created that combined a feedback curriculum with a card system designed to promote timely, effective feedback. Sites were randomized either to receive the intervention or to continue their current feedback method. All participants completed a Web-based survey before and after the intervention period. The primary outcome was overall feedback satisfaction on a 10-point scale. Additional items addressed specific aspects of feedback. Responses were compared using a generalized estimating equations model, adjusting for confounders and baseline differences between groups. The study was designed to achieve at least 80% power to detect a one-point difference in overall satisfaction (α = 0.05). RESULTS Response rates for pre- and postintervention surveys were 65.9 and 47.3% (faculty) and 64.7 and 56.9% (residents). Residents in the intervention group reported a mean overall increase in feedback satisfaction scores compared to those in the control group (mean increase 0.96 points, standard error [SE] ± 0.44, p = 0.03) and significantly higher satisfaction with the quality, amount, and timeliness of feedback. There were no significant differences in mean scores for overall and specific aspects of satisfaction between the faculty physician intervention and control groups. CONCLUSIONS An intervention designed to improve real-time feedback in the ED resulted in higher resident satisfaction with feedback received, but did not affect faculty satisfaction with the feedback given.

Racial differences in receiving morphine among prehospital patients with blunt trauma.

BACKGROUND Pain management is an important part of prehospital care, yet few studies have addressed the effects of age, sex, race, or pain severity on prehospital pain management. OBJECTIVES To examine the association of sex, age, race, and pain severity with analgesia administration for blunt trauma in the prehospital setting. METHODS In this retrospective cohort study, we used the automated registry of a large urban Emergency Medical Services agency to identify records of all patients transported for blunt trauma injuries between February 1 and November 1, 2009. We used bivariable and multivariable analyses with logistic regression models to determine the relationship between analgesia administration and patient sex, race, age, pain score on a pain scale, and time under prehospital care. RESULTS We identified 6398 blunt trauma cases. There were 516 patients (8%) who received analgesia overall; among patients for whom a pain scale was recorded, 25% received analgesia. By multivariable analysis, adjusting for race, sex, age, time with patient, and pain score, African-American and Hispanic patients were less likely than Caucasian patients to receive analgesia. Pain score and prehospital time were both significant predictors of analgesia administration, with higher pain score and longer prehospital time associated with increased administration of pain medication. Neither sex nor age was a significant predictor of analgesia administration in the regression analysis. CONCLUSION This study suggests that Caucasians are more likely than African-Americans or Hispanics to receive prehospital analgesia for blunt trauma injuries. In addition, patients with whom paramedics spend more time and for whom a pain score is recorded are more likely to receive analgesia.

Conference attendance does not correlate with emergency medicine residency in-training examination scores.

OBJECTIVES The residency review committee for emergency medicine (EM) requires residents to have greater than 70% attendance of educational conferences during residency training, but it is unknown whether attendance improves clinical competence or scores on the American Board of Emergency Medicine (ABEM) in-training examination (ITE). This study examined the relationship between conference attendance and ITE scores. The hypothesis was that greater attendance would correlate to a higher examination score. METHODS This was a multi-center retrospective cohort study using conference attendance data and examination results from residents in four large county EM residency training programs. Longitudinal multi-level models, adjusting for training site, U.S. Medical Licensing Examination (USMLE) Step 1 score, and sex were used to explore the relationship between conference attendance and in-training examination scores according to year of training. Each year of training was studied, as well as the overall effect of mean attendance as it related to examination score. RESULTS Four training sites reported data on 405 residents during 2002 to 2008; 386 residents had sufficient data to analyze. In the multi-level longitudinal models, attendance at conference was not a significant predictor of in-training percentile score (coefficient = 0.005, 95% confidence interval [CI] = -0.053 to 0.063, p = 0.87). Score on the USMLE Step 1 examination was a strong predictor of ITE score (coefficient = 0.186, 95% CI = 0.155 to 0.217; p < 0.001), as was female sex (coefficient = 2.117, 95% CI = 0.987 to 3.25; p < 0.001). CONCLUSIONS Greater conference attendance does not correlate with performance on an individuals ITE scores. Conference attendance may represent an important part of EM residency training but perhaps not of ITE performance.

How Prevalent Are Potentially Illegal Questions During Residency Interviews

Purpose To study the prevalence of potentially illegal questions in residency interviews and to identify the impact of such questions on applicants’ decisions to rank programs. Method Using an Electronic Residency Application Service–supported survey, the authors surveyed all applicants from U.S. medical schools to residency programs in five specialties (internal medicine, general surgery, orthopedic surgery, obstetrics–gynecology [OB/GYN], and emergency medicine) in 2006–2007. The survey included questions about the frequency with which respondents were asked about gender, age, marital status, couples matching, current children, intent to have children, ethnicity, religion, or sexual orientation, and the effect that such questions had on their decision to rank programs. Results Of 11,983 eligible applicants, 7,028 (58.6%) completed a survey. Of respondents, 4,557 (64.8%) reported that they were asked at least one potentially illegal question. Questions related to marital status (3,816; 54.3%) and whether the applicant currently had children (1,923; 27.4%) were most common. Regardless of specialty, women were more likely than men to receive questions about their gender, marital status, and family planning (P < .001). Among those respondents who indicated their specialty, those in OB/GYN (162/756; 21.4%) and general surgery (214/876; 24.4%) reported the highest prevalence of potentially illegal questions about gender. Being asked a potentially illegal question negatively affected how respondents ranked that program. Conclusions Many residency applicants were asked potentially illegal questions. Developing a formal interview code of conduct targeting both applicants and programs may be necessary to address the potential flaws in the resident selection process.

A Survey of Handoff Practices in Emergency Medicine

This study aimed to assess practices in emergency department (ED) handoffs as perceived by emergency medicine (EM) residency program directors and other senior-level faculty and to determine if there are deficits in resident handoff training. This cross-sectional survey study was guided by the Kern model for medical curriculum development. A 12-member Council of Emergency Medicine Residency Directors (CORD) Transitions in Care task force of EM physicians performed these steps and constructed a survey. The survey was distributed to the CORD listserv. There were 147 responses to the anonymous survey, which were collected using an online tool. At least 41% of the 158 American College of Graduate Medical Education EM residency programs were represented. More than half (56.6%) of responding EM physicians reported that their ED did not use a standardized handoff. There also exists a dearth of formal handoff training and handoff proficiency assessments for EM residents.

The July Effect: Is Emergency Department Length of Stay Greater at the Beginning of the Hospital Academic Year?

Introduction There has been concern of increased emergency department (ED) length of stay (LOS) during the months when new residents are orienting to their roles. This so-called “July Effect” has long been thought to increase LOS, and potentially contribute to hospital overcrowding and increased waiting time for patients. The objective of this study is to determine if the average ED LOS at the beginning of the hospital academic year differs for teaching hospitals with residents in the ED, when compared to other months of the year, and as compared to non-teaching hospitals without residents. Methods We performed a retrospective analysis of a nationally representative sample of 283,621 ED visits from the National Hospital Ambulatory Medical Care Survey (NHAMCS), from 2001 to 2008. We stratified the sample by proportion of visits seen by a resident, and compared July to the rest of the year, July to June, and July and August to the remainder of the year. We compared LOS for teaching hospitals to non-teaching hospitals. We used bivariate statistics, and multivariable regression modeling to adjust for covariates. Results Our findings show that at teaching hospitals with residents, there is no significant difference in mean LOS for the month of July (275 minutes) versus the rest of the year (259 min), July and August versus the rest of the year, or July versus June. Non-teaching hospital control samples yielded similar results with no significant difference in LOS for the same time periods. There was a significant difference found in mean LOS at teaching hospitals (260 minutes) as compared to non-teaching hospitals (185 minutes) throughout the year (p<0.0001). Conclusion Teaching hospitals with residents in the ED have slower throughput of patients, no matter what time of year. Thus, the “July Effect” does not appear to a factor in ED LOS. This has implications as overcrowding and patient boarding become more of a concern in our increasingly busy EDs. These results question the need for additional staffing early in the academic year. Teaching hospitals may already institute more robust staffing during this time, preventing any significant increase in LOS. Multiple factors contribute to long stays in the ED. While patients seen by residents stay longer in the ED, there is little variability throughout the academic year.

Prehospital Administration of Epinephrine in Pediatric Anaphylaxis

Abstract Anaphylaxis in the pediatric population is both serious and potentially lethal. The incidence of allergic and anaphylactic reactions has been increasing and the need for life saving intervention with epinephrine must remain an important part of Emergency Medical Services (EMS) provider training. Our aim was to characterize dosing and timing of epinephrine, diphenhydramine, and albuterol in the pediatric patient with anaphylaxis. In this retrospective chart review, we studied prehospital medication administration in pediatric patients ages 1 month up to 14 years old classified as having a severe allergic reaction or anaphylaxis. We compared rates of epinephrine, diphenhydramine, and albuterol given to patients with allergic conditions including anaphylaxis. In addition, we calculated the rate of epinephrine administration in cases of anaphylaxis and determined what percentage of time the epinephrine was given by EMS or prior to their arrival. Of the pediatric patient contacts, 205 were treated for allergic complaints. Of those with allergic complaints, 98 of 205 (48%; 95% CI 41%, 55%) had symptoms consistent with anaphylaxis and indications for epinephrine. Of these 98, 53 (54%, 95% CI 44%, 64%) were given epinephrine by EMS or prior to EMS arrival. Among the patients in anaphylaxis not given epinephrine prior to EMS arrival, 6 (12%; 95% CI 3%, 21%) received epinephrine from EMS, 10 (20%; 95% CI 9%, 30%) received diphenhydramine only, 9 (18%, 95% CI 7%–28%) received only albuterol and 17 (33%, 95% CI 20%–46%) received both albuterol and diphenhydramine. 9 patients in anaphylaxis received no treatment prior to arriving to the emergency department (18%, 95% CI 7%–28%). In pediatric patients who met criteria for anaphylaxis and the use of epinephrine, only 54% received epinephrine and the overwhelming majority received it prior to EMS arrival. EMS personnel may not be treating anaphylaxis appropriately with epinephrine.
