Why Do Physical Medicine and Rehabilitation Physicians Lose American Board of Physical Medicine and Rehabilitation Board Certification?

Objective Physicians can lose board certification through revocation related to professionalism violations or expiration due to failure to complete continuing certification requirements. The purpose of this study was to analyze the causes of board certification loss for physicians with board certification through the American Board of Physical Medicine and Rehabilitation. Design This retrospective cohort study analyzed the certification status of 5541 American Board of Physical Medicine and Rehabilitation diplomates between 1993 and 2019 to determine reasons for certification loss. A focused analysis of diplomates with expired certificates in 2019 was conducted to further examine reasons for certificate expiration. Results Of 5541 physicians, 496 (9%) had certification expiration due to failure to meet continuing certification requirements and 60 (1%) had certification revocation due to disciplinary actions, without regaining certification across the study years. A focused analysis of physicians with expired certificates in 2019 revealed that the majority had failed to complete multiple components of continuing certification. Practice improvement was the single most common incomplete requirement. Failure to pass the knowledge assessment was an uncommon cause for certification loss. Conclusions Certification expiration through failure to complete all continuing certification requirements, versus revocation, is responsible for most instances of board certification loss. Practice improvement was the most common incomplete requirement.
