A Longitudinal Study of Commonly Used Admissions Measures and Disenrollment from Medical School and Graduate Medical Education Probation or Termination from Training.

Introduction: This is an empirical study to better understand commonly used medical school admission measures and disenrollment decisions during undergraduate medical education as well as graduate medical education (GME) probation or termination decisions.

Materials And Methods: Based on the data of USUHS medical students matriculating between 1998 and 2011 (N = 2,460), we compared medical school graduates and those disenrolled from medical school on MCAT scores, undergraduate BCPM (Biology, Chemistry, Physics, Math) GPA, and undergraduate overall GPA. We also reported more specific reasons for disenrollment decisions. Next, we compared the students who were referred to the student promotion committee (SPC) with other students on these measures. Moving onto GME, we compared trainees who were put on probation or terminated from training with those who were not on MCAT and undergraduate GPA measures. In addition, we examined the association between being referred to the SPC and GME probation or termination.

Results: There were 2,347 graduates and 113 disenrolled students from medical school (4.8%). For the disenrolled students, 43 (38.7%) students were disenrolled for exclusively (or primarily) non-academic reasons, and 68 (61.3%) were disenrolled for exclusively (or primarily) academic reasons. The t-tests showed statistically significant differences on the MCAT score of the first attempt (t(2,449) = 7.22, P < 0.01, Cohen's d = 0.70), average MCAT score (t(2,449) = 4.22, P < 0.01, Cohen's d = 0.41), and highest MCAT score (t(2,449) = 3.51, P < 0.01, Cohen's d = 0.34). Logistic regression model selection also revealed that the best predictor for disenrollment was the first MCAT score (exp(b) = 0.83, 95% CI = (0.78, 0.88)). No significant differences on these measures were found from the group comparisons on SPC and GME probation or termination. There was no significant association between SPC appearance and GME probation or termination.

Conclusions: Academic difficulties, especially in the basic sciences, appear to be the most common factor for disenrollment from medical school. These students also had lower MCAT scores, particularly on the first attempt. The MCAT performance indicators and undergraduate GPA were consistently lower, but not statistically significant, for those who appeared before SPC or were put on probation or terminated from training during GME.
