an evaluation of non-uniform grade distribution with the emergency medicine off-service standardized letters of evaluation

Introduction: standardized letters of evaluation (sloes) are designed to objectively compare medical students to their peers for completed emergency medicine (em) rotations to be used in the em residency match. in an attempt to adapt quickly to the lack of availability of in-person em rotations due to covid restrictions, “off-service” sloes (osloes) were allowed in place of traditional sloes. the purpose of this study was to assess the utility of osloes for candidate selection during the 2020-21 application cycle at a single em residency.methods: a retrospective cohort review of all osloes submitted during the 2020-21 academic year to an em residency program was performed. a total of 270 osloes were eligible for review. summary statistics were calculated for the study variables recorded, including global rank, grade, categorical details, and rank.results: of the 270 osloes reviewed, 61.9% ranked candidates in the top 10% of their class, with 95% being ranked in the top two categories. over 90% of students were graded as honors or high pass and over 75% of students were ranked in the top 1/3 for each specific osloe category.conclusion: our findings reveal questionable utility of the objective measures in the osloe as there are signs it may suffer from non-uniform grade distribution, leading to low utility for candidate selection. our data shows marked over-ranking within the highest 2 categories. em program directors and faculty should use caution as the osloe may not carry the same weight as a traditional sloe when objectively evaluating prospectivestudents for a match into em.
