Three- vs. Four-Year Emergency Medicine Training Programs.

Postgraduate training in emergency medicine (EM) varies in length among different programs. This fact creates a dilemma for applicants to the specialty of EM and prevents EM educators from reaching a consensus regarding the optimal length of training. Historically, EM training existed in the postgraduate year (PGY) 1-3, 2-4, and 1-4 formats, until the PGY 2-4 program became obsolete in 2011-2012. Currently, three-quarters of EM programs follow the PGY 1-3 format. In this article, we clarify for the applicants the main differences between the PGY 1-3 and PGY 1-4 formats. We also discuss the institutional, personal, and graduate considerations that explain why an institution or an individual would choose one format over the other.
