Association of internship with performance on American Board of Physical Medicine and Rehabilitation certification examinations.

Physical Medicine and Rehabilitation (PM&R) residents must complete twelve months of fundamental skills training prior to beginning PM&R residency. The objective of this study is to determine if characteristics of the first post-graduate year (PGY-1) impact performance on American Board of PM&R (ABPMR) initial certification examinations. A retrospective review was conducted on a deidentified ABPMR database of physicians who completed PM&R residency and took the Part I Examination between 2008 and 2022. Physicians who completed categorical residency programs in PM&R had higher pass rates on Part I than physicians who completed advanced programs. Physicians who completed a categorical program had higher scaled scores on the Part II Examination than physicians who completed either a transitional or non-transitional advanced program but pass rates did not differ. Completing less than 3 months of training in internal medicine prior to starting PM&R was associated with lower Part I and Part II Examination scaled scores than completing 3 or more months. Physicians who completed six or more months of internal medicine had higher Part I and Part II Examination pass rates and scaled scores than physicians who completed six or more months in surgery.
