The Impact of a New Anesthesiology Residency Program on the Number of Medical Students Matching Into Anesthesiology at a Single Institution: A Retrospective Longitudinal Study.

Introduction There are projected workforce shortages within anesthesiology exacerbated by an increase in demand for anesthesia services and an aging anesthesia workforce. Given this mismatch, it is critical for the specialty to recruit the next generation of anesthesiologists and understand the factors affecting medical students' decision to apply to anesthesiology. This study aims to evaluate the impact of establishing a new anesthesiology residency program at a single institution on the number of medical students that match into anesthesiology in the subsequent years. Methods A single-center, retrospective longitudinal study examined the number of medical students matching into anesthesiology at a single institution between 2013 and 2023, five years before and after the establishment of an accredited anesthesiology residency program. The data were compared to aggregated data on all US medical student applicants through the National Resident Matching Program. Results The pre-anesthesiology residency match rate (2013-2018) of medical students from Alpert Medical School (AMS) was 2.47% while the post-anesthesiology residency match rate (2019-2023) was 4.30%. This represents a 74% increase in the average proportion of medical students matching into anesthesiology after the start of the residency program compared to a 20% increase nationally over the same time period. The rate of change of AMS matched applicants after the implementation of the AMS anesthesia residency program increased compared to the national applicant pool (p= 0.002). Conclusion The establishment of a new accredited anesthesiology residency program increased the proportion of medical students matching into anesthesiology at the affiliated medical school in the subsequent five years. Exposure to an academic anesthesiology program improves medical student interest and ultimately matches rates in anesthesiology, a vital tool to address the projected shortages in the anesthesiology workforce.
