The COVID-19 pandemic has dramatically disrupted the educational experience of medical trainees. However, a detailed characterization of exactly how trainees' clinical experiences have been affected is lacking. Here, we profile residents' inpatient clinical experiences across the four training hospitals of NYU's Internal Medicine Residency Program during the pandemic's first wave. We mined ICD-10 principal diagnosis codes attributed to residents from February 1, 2020, to May 31, 2020. We translated these codes into discrete medical content areas using a newly developed "crosswalk tool." Residents' clinical exposure was enriched in infectious diseases (ID) and cardiovascular disease content at baseline. During the pandemic's surge, ID became the dominant content area. Exposure to other content was dramatically reduced, with clinical diversity repopulating only toward the end of the study period. Such characterization can be leveraged to provide effective practice habits feedback, guide didactic and self-directed learning, and potentially predict competency-based outcomes for trainees in the COVID era.
