Differences Between Emergency Medicine Residency Programs That Accept the Comprehensive Osteopathic Medical Licensing Examination of the United States and Those That Prefer or Only Accept the United States Medical Licensing Examination.

Introduction The Comprehensive Osteopathic Medical Licensing Examination of the United States (COMLEX-USA) is a three-part series of examinations similar to the United States Medical Licensing Examination (USMLE) that osteopathic medical students must pass for medical licensure. Osteopathic students are not required to take the USMLE, but during the residency admission process, many emergency medicine (EM) residency programs will not consider osteopathic applicants who only take the COMLEX-USA. Therefore, we examined program-level characteristics between programs that accept the COMLEX-USA alone for osteopathic applicants and those that prefer the USMLE using free, publicly available online databases and residency program websites. Methods Emergency Medicine Residents' Association (EMRA) Match was the primary database used; however, missing exam preferences were supplemented from Fellowship and Residency Electronic Interactive Database Access (FREIDA) and individual program websites. Program characteristics were compared between EM residencies that accept the COMLEX-USA and those that prefer the USMLE using the Chi-square test for categorical variables and the Mann-Whitney test for interval variables. Results Two hundred sixty of the 278 EM programs in the dataset were included in the analyses. One hundred and seven programs reported preferring the USMLE, while 151 reported accepting the COMLEX-USA alone. Programs differed by the educational environment of the primary training site (p <0.001), number of Standardized Letter(s) of Evaluation (SLOE) needed for an interview (p = 0.042), emergency department (ED) shift length (p = 0.021), former American Osteopathic Association accreditation (p <0.001), percentage of osteopathic residents (p <0.001), annual ED volume (p = 0.001), number of intern positions (p <0.001), and number of elective weeks (p = 0.028). Conclusion EM residency programs that reported accepting the COMLEX-USA alone for osteopathic applicants differed from those that prefer the USMLE. Therefore, osteopathic medical students interested in EM should consider these differences when deciding whether to take the USMLE.
