A Retrospective Cohort Study of the Effect of Home Institution on Emergency Medicine Standardized Letters of Evaluation

Abstract

BACKGROUND: The standardized letter of evaluation (SLOE) was developed to make letters of recommendation in emergency medicine (EM) more objective and discerning. Typically, students obtain one SLOE from a home EM rotation and at least one more SLOE from an away clerkship. It is unclear if students perform better on their home or away EM rotations. OBJECTIVE: The purpose of this study was to determine if students perform better on the group SLOE at their home institution compared to an away institution. METHODS: The authors performed a retrospective application review of all allopathic applicants to an urban, academic EM residency program. The authors calculated a composite score (CS) for each group SLOE, using the global assessment scores for comparative rank and rank list position. A lower CS indicates better performance. The authors compared mean CS for students' first home rotations with first away rotations. For students in the study who had a third (second away or second home site) SLOE available, the authors compared mean CS on the students' first SLOEs with mean CS on the students' third SLOEs. RESULTS: A total of 624 records were included in the primary analysis. There was a small, but significant difference between mean CS for students' home rotations when compared to away rotations (4.67 vs. 4.85, p = 0.024). Students performed better on their home rotations. Students who had three SLOEs available performed worse on their third rotation (first = 4.40, second = 4.63, third = 4.77, p = 0.012 for first vs. third). For all available SLOEs, more than 50% of students fell into the top 10% or top one-third categories. CONCLUSION: Students perform slightly better on their home EM rotations. Students' mean SLOE CS is slightly worse for a third rotation when compared to a first rotation.
