Factors Associated With Infectious Disease Fellowship Fill Rate: An Analysis of 2019, 2020, and 2021 Match Cycles

Historically, there has been a relative paucity of applicants to infectious disease fellowships. This leads to a significant number of programs being unfilled in the fellowship match. We sought to identify predictors of a program filling all positions offered in the match through retrospective review of available match and program data for the 2019-2021 match cycles. In the 2021 match, hospital and research rankings were associated with filling, as were offering specialized training tracks and having an active Twitter account. Knowledge of these associations can help programs direct resources to optimize recruitment and enrichment of infectious disease fellows.
