Rate of USMLE Step 2 CK Scores Included on Orthopedic Surgery Applications and Associations With Step 1 Score.

Abstract

BackgroundAt present, orthopedic surgery applicants do not universally include Step 2 Clinical Knowledge (Step 2 CK) scores on their applications and current inclusion rates are not yet reported. As Step 1 transitions to pass/fail scoring, we suspect more applicants will include Step 2 CK scores. We sought to identify what percentage of applications currently include Step 2 CK, if applicants who include Step 2 CK (Step 1+CK) score lower on Step 1 than those not including Step 2 CK (Step 1-CK), and what correlations exist between Step 1 and Step 2 CK scores among those who include the scores on their applications.MethodologyApplicants to one residency program over two application cycles (2019-2020) were analyzed. The percentage including Step 1 and Step 2 scores was recorded. Step 1 scores were compared between Step 1+CK and Step 1-CK applicants. Differences between Step 2 CK and Step 1 scores were stratified by Step 1 score.ResultsA total of 1,688 applicants applied to our institution from 2019 to 2020. Of those reporting United States Medical Licensing Examination scores, 1,316/1,660 (79%) reported a Step 2 CK score. Step 1-CK applicants scored higher on Step 1 (250.7 ± 10.9) versus Step 1+CK applicants (244.3 ± 13.1) (p < 0.0001). More applicants who scored lower on Step 1 improved upon their percentile rank between Step 1 and Step 2 CK than those who scored higher on Step 1 (χ2(8,1316) = 79.1, p < 0.0001).ConclusionsFrom 2019 to 2020, 79% of applicants included Step 2 CK. Lower Step 1 scores were more likely to include Step 2 CK and improve upon their percentile score. It is unclear how Step 1 scoring change will affect current practice.
