Multiple Medical Students on a Clerkship Team: Do They Affect Each Others’ Grades?

Background Medical students are often paired together on clinical teams during their clerkships, but the effect of this practice on student performance is unknown. The primary objectives of this study were (1) to retrospectively assess whether students paired together on a medical team during their Internal Medicine sub-internship affected each other’s grade and (2) to survey medical students’ perceptions on the impact of pairing on their evaluations. Methods We examined clerkship grades of 186 student-pairs at 3 sub-internship hospital sites of Harvard Medical School from 2013-2017. To evaluate student perceptions we administered a survey to the graduating class of 2018. Results There was no significant deviation between the expected and observed distribution of student grades (p=0.39) among 186 student pairs, suggesting that pairing had no meaningful effect on the sub-internship grade. We also saw no effect when controlling for prior internal medicine clerkship performance (p=0.53). We then surveyed students in the 2018 graduating class assessing student perceptions on pairing. Of the 99 respondents (59% response rate), 90% and 87% of respondents felt that being paired affected their evaluations by resident and attending physicians, respectively. Conclusions Our analysis suggests that paired medical students do not meaningfully affect each others’ grades, despite the majority of surveyed students believing that being paired affects their evaluations. Awareness of student perceptions regarding pairing can inform clerkship structure and be utilized to address student concerns.
