In response to a recent proposal to change scoring on the United States Medical Licensing (USMLE) Step 1 exam to pass/fail, we sought to determine the value of numerical Step 1 scores in predicting success in our radiology residency program.
Residency applications for 157 residents entering the program between 2005 and 2017 were retrospectively reviewed. Biographical (gender, sports participation, advanced degree), undergraduate (school, major), and medical school (grades, USMLE Step 1 score, Alpha Omega Alpha membership, letters of recommendation, publications) data were recorded. Multivariate regression analysis was used to examine the relationship between these application factors and subsequent performance as a radiology resident, as determined by completion of the program without requiring corrective action, select Accreditation Council for Graduate Medical Education milestones, and selection as chief resident.
Corrective action was required for 7% (n = 12) of residents. Of the predictor variables, only Step 1 score was associated with the need for corrective action (p < 0.001). The interpretation of exams milestone was associated with higher Step 1 scores (p = 0.001) and number of medical school clerkship honors (p = 0.008). Selection as chief resident was associated with sports participation (p = 0.04), and clerkship honors (p = 0.02).
Numerical USMLE Step 1 scores are predictive of successful completion of radiology residency training without the need for corrective action, and of accelerated competence in the interpretation of exams milestone. Continued reporting of numerical Step 1 scores would be valuable in selection of radiology residents.
针对美国医师执照考试（USMLE）第 1 步考试成绩改为通过/不通过的提议，我们旨在确定第 1 步考试的分数在预测我们放射科住院医师培训项目中的成功方面的价值。
回顾性分析了 2005 年至 2017 年期间入读该项目的 157 名住院医师的住院医师申请。记录了传记（性别、运动参与、高等学位）、本科（学校、专业）和医学院（成绩、USMLE 第 1 步成绩、Alpha Omega Alpha 会员、推荐信、出版物）的数据。采用多元回归分析检查这些申请因素与随后作为放射科住院医师的表现之间的关系，表现由完成该项目且无需采取纠正措施、达到研究生医学教育认证委员会的里程碑以及被选为住院医师主任来确定。
有 7%（n=12）的住院医师需要采取纠正措施。在预测变量中，只有第 1 步成绩与需要采取纠正措施相关（p<0.001）。考试里程碑的解释与较高的第 1 步成绩（p=0.001）和医学院实习荣誉数量（p=0.008）相关。被选为住院医师主任与运动参与（p=0.04）和实习荣誉（p=0.02）相关。
美国医师执照考试第 1 步考试的分数可预测放射科住院医师培训的成功完成，无需采取纠正措施，以及考试里程碑解释的能力提升。继续报告第 1 步考试的分数对于放射科住院医师的选择很有价值。
