Clerkships in Emergency Medicine.

Planning for clerkships in emergency medicine (EM) can be stressful, prolonged, and challenging. Therefore, medical students should start planning for them early. In this article, we offer guidance regarding several issues pertinent to the EM clerkship, such as the best time to schedule one (or more) during medical school, the most appropriate institution or program to schedule it, the process of selecting and applying for the clerkship, and the number of EM clerkships to consider. We will explain why an EM clerkship should be scheduled between June and October and the reason that 2 EM clerkships at different sites are sufficient for the majority of students. Additionally, we emphasize that clerkships in emergency departments associated with EM residency programs or with reputations for outstanding student teaching tend to be most beneficial. Above all, students interested in EM should attempt to leave a great impression after completing their clerkships by providing stellar patient care, demonstrating enthusiasm at all times, and maintaining professionalism. In turn, they will gain knowledge and clinical experiences that should prove valuable in their future.

Anemia.

Patients with anemia are frequently encountered in the emergency department (ED); emergency physicians (EPs) often play an important role in the evaluation and management of anemia. Although many patients have findings consistent with anemia on routine laboratory tests, only a small percentage will require acute intervention. An understanding of the broader types of anemia and how to manage such patients is important in the practice of an EP, as the presence of anemia will impact treatment plans for a variety of other disorders. This article reviews the evaluation and management of adult patients presenting to the ED with anemia.

The Standardized Letter of Evaluation for Postgraduate Training: A Concept Whose Time Has Come?

A medical student's letter of recommendation for postgraduate training applications should provide a fair and accurate assessment of academic and clinical performance, as well as define character attributes pertinent to the practice of medicine. Since its inception in 1997, the emergency medicine (EM) standardized letter of evaluation (SLOE) has evolved into an instrument that provides just such an assessment. Concise, standardized, and discriminating in its assessment of performance relevant to the practice of EM, the SLOE is judged by program directors in EM as the most valuable component of a potential resident's application. Other specialties would benefit from such a specialty-specific perspective, which is currently lacking in most Electronic Residency Application Service application materials. Creation of specialty-specific SLOEs which define performance metrics or competencies and noncognitive personality traits critical to each unique specialty would add substantially to the holistic review of our graduating students. As a result, specialty-specific SLOEs would increase the likelihood that programs could effectively identify applicants who would not only be a "good fit" for their programs but also graduate to become successful physicians.

Council of emergency medicine residency directors standardized letter of recommendation writers' questionnaire.

BACKGROUND: The Council of Emergency Medicine Residency Directors (CORD) Standardized Letter of Recommendation (SLOR) has become the primary tool used by emergency medicine (EM) faculty to evaluate residency candidates. A survey was created to describe the training, beliefs, and usage patterns of SLOR writers. METHODS: The SLOR Task Force created the survey, which was circulated to the CORD listserv in 2012. RESULTS: Forty-six percent of CORD members (320 of 695) completed the survey. Of the respondents, 39% (125 of 320) had fewer than 5 years of experience writing SLOR letters. Most were aware of published guidelines, and most reported they learned how to write a SLOR on their own (67.4%, 182 of 270). Sixty-eight percent (176 of 258) admitted to not following the instructions for certain questions. Self-reported grade inflation occurred "rarely" 36% (97 of 269) of the time and not at all 40% (107 of 269) of the time. CONCLUSIONS: The CORD SLOR has become the primary tool used by EM faculty to evaluate candidates applying for residency in EM. The SLOR has been in use in the EM community for 16 years. However, our study has identified some problems with its use. Those issues may be overcome with a revised format for the SLOR and with faculty training in the writing and use of this document.

Characterization of the Council of Emergency Medicine Residency Directors' standardized letter of recommendation in 2011-2012.

OBJECTIVES: The Council of Emergency Medicine Residency Directors (CORD) introduced the standardized letter of recommendation (SLOR) in 1997, and it has become a critical tool for assessing candidates for emergency medicine (EM) training. It has not itself been evaluated since the initial studies associated with its introduction. This study characterizes current SLOR use to evaluate whether it serves its intended purpose of being standardized, concise, and discriminating. METHODS: This retrospective, multi-institutional study evaluated letters of recommendation from U.S. allopathic applicants to three EM training programs during the 2011-2012 Electronic Residency Application Service (ERAS) application cycle. Distributions of responses to each question on the SLOR were calculated, and the free-text responses were analyzed. Two pilots, performed on five applicants each, assisted in developing a strategy for limiting interrater reliability. RESULTS: Each of the three geographically diverse programs provided a complete list of U.S. allopathic applicants to their program. Upon randomization, each program received a list of coded applicants unique to their program randomly selected for data collection. The number of applicants was selected to reach a goal of approximately 200 SLORs per site (n = 602). Among this group, comprising 278 of 1,498 applicants (18.6%) from U.S. allopathic schools, a total of 1,037 letters of recommendation were written, with 724 (69.8%) written by emergency physicians. SLORs represented 57.9% (602/1037) of all LORs (by any kind of author) and 83.1% (602/724) of letters written by emergency physicians. Three hundred ninety-two of 602 SLORs had a single author (65.1%). For the question on "global assessment," students were scored in the top 10% in 234 of 583 of applications (40.1%; question not answered by some), and 485 of 583 (83.2%) of the applicants were ranked above the level of their peers. Similarly, >95% of all applicants were ranked in the top third compared to peers, for all but one section under "qualifications for emergency medicine." For 405 of 602 of all SLORs (67.2%), one or more questions were left unanswered, while 76 of all SLORs (12.6%) were "customized" or changed from the standard template. Finally, in 291 of 599 of SLORs (48.6%), the word count was greater than the recommended maximum of 200 words. CONCLUSIONS: Grade inflation is marked throughout the SLOR, limiting its ability to be discriminating. Furthermore, template customization and skipped questions work against the intention to standardize the SLOR. Finally, it is not uncommon for comments to be longer than guideline recommendations. As an assessment tool, the SLOR could be more discerning, concise, and standardized to serve its intended purpose.

Diagnosis and management of urinary tract infection and pyelonephritis.

Urinary tract infections (UTIs) are the most common bacterial infections treated in the outpatient setting and range in severity from minimally symptomatic cystitis to severe septic shock in a wide array of patients. Diagnosis of uncomplicated cystitis can be inferred from history and physical, and confirmed by urinalysis. Appropriate antimicrobial therapy should rapidly improve symptoms in all UTIs. Treatment can be further tailored according to severity of illness, analysis of individualized risk factors, and antimicrobial resistance patterns. This article discusses treatment options in light of bacterial resistance in the twenty-first century.

House officer procedure documentation using a Personal Digital Assistant: a longitudinal study.

BACKGROUND: Personal Digital Assistants (PDAs) have been integrated into daily practice for many emergency physicians and house officers. Few objective data exist that quantify the effect of PDAs on documentation. The objective of this study was to determine whether use of a PDA would improve emergency medicine house officer documentation of procedures and patient resuscitations. METHODS: Twelve first-year Emergency Medicine (EM) residents were provided a Palm V (Palm, Inc., Santa Clara, California, USA) PDA. A customizable patient procedure and encounter program was constructed and loaded into each PDA. Residents were instructed to enter information on patients who had any of 20 procedures performed, were deemed clinically unstable, or on whom follow-up was obtained. These data were downloaded to the residency coordinator's desktop computer on a weekly basis for 36 months. The mean number of procedures and encounters performed per resident over a three year period were then compared with those of 12 historical controls from a previous residency class that had recorded the same information using a handwritten card system for 36 months. Means of both groups were compared a two-tailed Student's t test with a Bonferroni correction for multiple comparisons. One hundred randomly selected entries from both the PDA and handwritten groups were reviewed for completeness. Another group of 11 residents who had used both handwritten and PDA procedure logs for one year each were asked to complete a questionnaire regarding their satisfaction with the PDA system. RESULTS: Mean documentation of three procedures significantly increased in the PDA vs handwritten groups: conscious sedation 24.0 vs 0.03 (p = 0.001); thoracentesis 3.0 vs 0.0 (p = 0.001); and ED ultrasound 24.5 vs. 0.0 (p = 0.001). In the handwritten cohort, only the number of cardioversions/defibrillations (26.5 vs 11.5) was statistically increased (p = 0.001). Of the PDA entries, 100% were entered completely, compared to only 91% of the handwritten group, including 4% that were illegible. 10 of 11 questioned residents preferred the PDA procedure log to a handwritten log (mean +/- SD Likert-scale score of 1.6 +/- 0.9). CONCLUSION: Overall use of a PDA did not significantly change EM resident procedure or patient resuscitation documentation when used over a three-year period. Statistically significant differences between the handwritten and PDA groups likely represent alterations in the standard of ED care over time. Residents overwhelmingly preferred the PDA procedure log to a handwritten log and more entries are complete using the PDA. These favorable comparisons and the numerous other uses of PDAs may make them an attractive alternative for resident documentation.

Coombs-positive hemolytic anemia secondary to brown recluse spider bite: a review of the literature and discussion of treatment.

The bite of the brown recluse spider (Loxosceles reclusa) typically results in local, dermonecrotic skin lesions. Rarely, these bites may precipitate systemic disturbances of varying severity collectively known as systemic loxoscelism. The more severe systemic alterations attributed to the venom of this arachnid include hemolytic anemia, multiorgan failure, disseminated intravascular coagulation, or even death. Coombs-positive hemolysis associated with brown recluse spider bites has rarely been documented in the literature. We report 2 cases of systemic loxoscelism in young women associated with severe Coombs-positive hemolytic anemia and systemic symptoms requiring hospitalization. Both patients were treated with aggressive wound care, hematologic monitoring with blood transfusion, and intravenous fluid replacement. Recovery was excellent in both cases. We review the literature and discuss the controversies surrounding the treatment of more severe brown recluse bite reactions.

Vascular endothelial growth factor receptor-2 induces survival of hematopoietic progenitor cells.

Vascular endothelial growth factor (VEGF) and its receptors play an essential role in the formation and maintenance of the hematopoietic and vascular compartments. The VEGF receptor-2 (VEGFR-2) is expressed on a population of hematopoietic cells, although its role in hematopoiesis is still unclear. In this report, we have utilized a strategy to selectively activate VEGFR-2 and study its effects in primary bone marrow cells. We found that VEGFR-2 can maintain the hematopoietic progenitor population in mouse bone marrow cultured in the absence of exogenous cytokines. Maintenance of the hematopoietic progenitor population is due to increased cell survival with minimal effect on proliferation. Progenitor survival is mainly mediated by activation of the phosphatidylinositol 3'-kinase/Akt pathway. Although VEGFR-2 also activated Erk1/2 mitogen-activated protein kinase, it did not induce cell proliferation, and blockade of this pathway only partially decreased VEGFR-2-mediated survival of hematopoietic progenitors. Thus, the role of VEGFR-2 in hematopoiesis is likely to maintain survival of hematopoietic progenitors through the activation of antiapoptotic pathways.
