The importance of USMLE step 2 on the screening and selection of applicants for general surgery residency positions

BACKGROUND: As announced by the Federation of State Medical Boards (FSMB) and National Board of Medical Examiners (NBME), the United States Medical Licensing Examination (USMLE) Step 1 score reporting has transitioned to pass/fail outcomes instead of the traditional numeric score after January 26, 2022. USMLE Step 1 scores have been used widely as a crucial tool in screening and selecting applicants for residency programs. This study aims to determine the role of USMLE Step 2 in the selection of applicants for general surgery residency. METHODS: A retrospective study was conducted over six recruiting cycles from 2016 to 2021. The data from 334 interviewed applicants from one general surgery residency program were assessed. Data analyzed included USMLE Step 1 and Step 2 scores, applicant gender, Alpha Omega Alpha (AOA) status, letters of recommendation (LOR), and research/publications (RS). RESULTS: Of the 334 interviewed applicants, 209 (62.6%) were male. The mean [SD] USMLE Step 1 and USMLE Step 2 C K (Clinical Knowledge) scores were 239.6 [±10.4] and 249.2 [±11.4], respectively. The mean (SD) LOR and RS scores were 4.24 [±0.4] and 3.9 [±0.7], respectively. A positive correlation was observed between USMLE Step 1 and USMLE Step 2 C K (Clinical Knowledge) scores (r = 0.60, p < .001), LOR scores (r = 0.24, p = .008), and AOA status (r = 0.19, p = .038). There was a negligible correlation between USMLE scores and applicant gender. CONCLUSION: Transitioning USMLE Step 1 to pass/fail will make the initial screening and selection process of applications challenging for residency programs. In the short term, USMLE Step 2 scores, LOR, and AOA status are important as screening assessments. Valid measures to ensure appropriate, equitable, and fair assessments are needed.
