USMLE step 1 and step 2 CK as indicators of resident performance

Abstract

Abstract Background The purpose of this systematic review was to (1) determine the scope of literature measuring USMLE Step 1 and Step 2 CK as predictors or indicators of quality resident performance across all medical specialties and (2) summarize the ability of Step 1 and Step 2 CK to predict quality resident performance, stratified by ACGME specialties, based on available literature. Methods This systematic review was designed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) [16]. The original search strategy surveyed MEDLINE and was adapted to survey Cochrane Library and Embase. A study was deemed eligible if it provided all three of the following relevant information: (a) Step 1 or Step 2 CK as indicators for (b) resident outcomes in (c) any ACGME accredited specialty training program. Results A total of 1803 articles were screened from three separate databases. The 92 included studies were stratified by specialty, with Surgery (21.7% [20/92]), Emergency Medicine (13.0% [12/92]), Internal Medicine (10.9% [10/92]), and Orthopedic Surgery (8.7% [8/92]) being the most common. Common resident performance measures included ITE scores, board certification, ACGME milestone ratings, and program director evaluations. Conclusions Further studies are imperative to discern the utility of Step 1 and Step 2 CK as predictors of resident performance and as tools for resident recruitment and selection. The results of this systematic review suggest that a scored Step 1 dated prior to January 2022 can be useful as a tool in a holistic review of future resident performance, and that Step 2 CK score performance may be an effective tool in the holistic review process. Given its inherent complexity, multiple tools across many assessment modalities are necessary to assess resident performance comprehensively and effectively.
