Parallel Application to U.S. Psychiatry Residency Programs: Trends in Frequency and Differences by Applicant Group, 2009-2021.

Objective: The present study examines trends of percent of applicants, number of specialties, and specialty combinations for psychiatry residency applicants applying to multiple specialties (parallel application).

Methods: The authors conducted a retrospective analysis of data captured by the Association of American Medical Colleges Electronic Residency Application System for applicants to psychiatry residency between 2009 and 2021. The percent parallel-applying, the mean number of specialties, mean application counts, and frequency of specialty combinations with psychiatry residency were determined.

Results: The dataset described 67,261 applicants. The percentage parallel-applying decreased from 73.7% in 2009 to 60.0% in 2021. International Medical Graduates and U.S. International Medical Graduate parallel-applied at the greatest rate in each year. Applicants who were parallel-applying submitted larger numbers of applications compared to those who were single-specialty applying.

Conclusions: Parallel application to psychiatry residency appears to be a common practice, but has decreased in frequency. However, the mean numbers of applications submitted to each specialty in parallel application combination and among single-specialty applicants have increased. This practice appears to have a disproportionate impact on international and osteopathic applicants. Additional efforts are needed to develop evidence-based advising tools to reduce the number of residency applications submitted to psychiatry programs.
