Ethnic and Racial Differences in Ratings in the Medical Student Standardized Letters of Evaluation (SLOE).

Background: The Standardized Letter of Evaluation (SLOE) stratifies the assessment of emergency medicine (EM) bound medical applicants. However, bias in SLOE, particularly regarding race and ethnicity, is an underexplored area. Objective: This study aims to assess whether underrepresented in medicine (UIM) and non-UIM applicants are rated differently in SLOE components. Methods: This was a cross-section study of EM-bound applicants across 3 geographically distinct US training programs during the 2019-2020 application cycle. Using descriptive and regression analyses, we examine the differences between UIM applicants and non-UIM applicants for each of the SLOE components: 7 qualifications of an EM physician (7QEM), global assessment (GA) rating, and projected rank list (RL) position. Results: Out of a combined total of 3759, 2002 (53.3%) unique EM-bound applicants were included. UIM applicants had lower ratings for each of the 7QEM questions, GA, and RL positions. Compared to non-UIM applicants, only some of the 7QEM components: "Work ethic and ability to assume responsibility," "Ability to work in a team, and "Ability to communicate a caring nature," were associated with their SLOE. "Commitment to EM" correlated more with GA for UIM than for non-UIM applicants. Conclusions: This study shows a difference in SLOE rating, with UIM applicants receiving lower ratings than non-UIM applicants.

Gender differences in emergency medicine standardized letters of evaluation.

Objectives: The Standardized Letter of Evaluation (SLOE) is a vital portion of any medical student's emergency medicine (EM) residency application. Prior literature suggests gender bias in EM SLOE comparative ranking, but there is limited understanding of the impact of gender on other SLOE components. The study objective was to evaluate the presence of gender differences in the 7 Qualifications for EM (7QEM), Global Assessment (GA), and anticipated Rank List (RL) position. A secondary objective was to evaluate the gender differences in 7QEM scores and their link to GA and anticipated RL position. Methods: We performed a cross-sectional study using SLOEs from a subset of United States applicants to three EM residency programs during the 2019-2020 application cycle. We collected self-reported demographics, 7QEM scores, GA, and anticipated RL position. We utilized linear regression analyses and repeated measures ANOVA to evaluate if the relationship between the 7QEM scores, GA score, and anticipated RL position was different for men and women. Results: 2103 unique applicants were included (38.6% women, 61.4% men), with 4952 SLOEs meeting inclusion criteria. The average QEM (2.51 vs. 2.39; p < 0.001), GA (2.68 vs. 2.48; p < 0.001), and RL (2.68 vs. 2.47; p < 0.001) scores were statistically higher for women than men. When exploring the relationship between the 7QEM and GA, Ability to communicate a caring nature to patients was not found to be a statistically significant predictor for men, but it was for women. When exploring the relationship between 7QEM and RL, Commitment to EM was not a significant predictor for men, but it was for women. Conclusions: Women scored higher than men on the 7QEM, GA, and anticipated RL position on SLOEs. The 7QEM scores factored differently for men and women.

The standardized letter of evaluation in emergency medicine: Are the qualifications useful?

OBJECTIVES: The standardized letter of evaluation (SLOE) in emergency medicine (EM) is a widely used metric for determining interview invitations and ranking of candidates. Previous research has questioned the validity of certain sections of the SLOE. However, there remains a paucity of literature on the qualifications for EM section, which evaluates seven attributes of applicants. The aim of this study was to determine the correlation between the qualifications questions and grades, global assessment, and anticipated rank list position for EM applicants. METHODS: A multi-institutional cross-sectional study was performed using SLOEs from applicants to three geographically distinct U.S. EM residency programs during the 2019-2020 application cycle. We abstracted EM rotation grade, qualifications scores, global assessment, and anticipated rank list position from the SLOEs. A Spearman correlation was calculated between each of the qualifications scores and the applicant's grades, global assessment, and anticipated rank list position in a pairwise fashion. RESULTS: In total, 2,106 unique applicants (4,939 SLOEs) were included. Of the seven qualifications for EM questions, three were moderately to strongly correlated with global assessment and anticipated rank list position: "ability to develop and justify an appropriate differential and a cohesive treatment plan" (ρ = 0.65 and ρ = 0.63, respectively; p < 0.001), "how much guidance do you predict this applicant will need during residency?" (ρ = 0.68 and ρ = 0.68, respectively; p < 0.001), and "what is your prediction of success for the applicant?" (ρ = 0.69 and ρ = 0.69, respectively; p < 0.001). There was no strong correlation between the seven qualifications and grades. CONCLUSIONS: There was a moderate to strong correlation between three of seven qualifications for EM questions (ability to develop and justify a differential and develop a cohesive plan, anticipated need for the amount of guidance, and prediction of success) with both global assessment and anticipated rank list position, suggesting that these qualifications may provide the most useful data to residency selection while some of the other factors may not be needed.

The Utility of Midline Intravenous Catheters in Critically Ill Emergency Department Patients.

STUDY OBJECTIVE: Midline catheters are an alternative to more invasive types of vascular access in patients in whom obtaining peripheral access has proven difficult. Little is known of the safety and utility of midline catheters when used more broadly in critically ill patients in the emergency department (ED). These are long peripheral catheter, ranging from 10 to 25 cm in length, typically placed with assistance of ultrasound and the Seldinger's technique. We describe our experience with the use of midline catheters in the ED. METHODS: We conducted a prospective observational case series of all patients who had a midline catheter insertion attempted in the ED. We prospectively captured data on indication, technique, location, catheter type, number of attempts, overall success or failure, vasoactive use, and complications (daily catheter patency, flow, site appearance, and dwell-time complications). RESULTS: From January 28, 2016, to December 30, 2017, practitioners placed 403 midline catheters. Catheter insertion success was 99%, and the median number of attempts was 1 (interquartile range 1 to 1; minimum 1; maximum 3). The median number of days the catheter remained in place was 5 (interquartile range 2 to 8). Failure to aspirate occurred in 57 patients (14%; 95% confidence interval 11% to 18%). Overall, 10 patients (2.5%; 95% confidence interval 1.2% to 4.5%) experienced 10 insertion-related complications. During the study period, 49 patients (12%; 95% confidence interval 9% to 16%) experienced 60 dwell-time-related complications. Severe complications occurred in 3 patients (0.7%). CONCLUSION: Midline catheters may present a feasible alternative to central venous access in certain critically ill ED patients.

A two-culture method for exposure of human brain organotypic slice cultures to replicating human immunodeficiency virus type 1.

To evaluate the effect of HIV-1 virus on neural cells, we have developed a method to culture human fetal organotypic brain slices in the presence of live virus. Brain slices were placed on semipermeable hydrophilic membrane inserts, resting on top of wells that contain cultured H9 T-cells chronically producing HIV-1. This system allows free exposure of the brain slices to HIV-1, HIV-1 proteins, and other molecules released by the infected T-cells. After specific lengths of time in culture, slices were stained for viability with Calcein-AM and propidium iodide, for neural cell markers such as GFAP, nestin and ß-III-tubulin, tested for cell proliferation, and analyzed by fluorescent and confocal microscopy. When cultured in the presence of neural progenitor medium lacking serum, slices were viable and maintained active cell replication for at least 3 weeks in culture, without significant cell death. By comparison with slices co-cultured with uninfected T-cells or with medium alone, slices cultured in the presence of HIV-1 showed increased nestin and GFAP. Moreover, in slices exposed to HIV-1-producing H9 cells, regions of nestin stain were, over time in culture, replaced with GFAP stain. This suggested the process of gliosis often found in brains of HIV-1 infected individuals. This co-culture method can be used to model the dynamics and the microenvironment of brain tissue exposed to HIV-1 and can potentially be used to test therapies directed at preventing HIV-1-induced neural damage.
