摘要

Background The purpose of this study is to evaluate the relationship between American College of Radiology (ACR) in-training examination scores and performance on the Royal College of Physicians and Surgeons of Canada (RCPSC) radiology licensing examination. Methods Percentile ACR examination scores for 67 residents were obtained from 1995 to 2011 for four years of training and compared with results of the RCPSC examination. Mean ACR scores of residents who passed and residents who failed their RCPSC examination were compared with a t-test. ACR scores and licensing examination results were correlated. Logistic regression was used to predict the probability of failure given an individual’s ACR score. Receiver Operating Characteristic (ROC) curves were developed in order to estimate a threshold ACR score at or above which the risk of failure was negligible. Results The ACR scores between residents who passed their licensing exam and those who failed were significantly different. There was moderate correlation between ACR scores and exam results. Using ROC curves for each year of training, the threshold ACR scores at or above which there was a negligible risk of exam failure were 32, 42, 63, and 47 for training years 1, 2, 3 and 4 respectively. Logistic regression curves, with 95% confidence intervals, were plotted for each year of training to predict RCPSC exam results based on an individual’s ACR score. Conclusions ACR exam scores are a strong predictor of RCPSC examination performance. Percentile ACR scores can be used to identify residents at risk for future examination failure.
