Commentary: Review of Mandatory Maintenance of Certification in the USA.

The goal of maintenance of certification (MOC) activities is to ensure physicians are up to date on current practices and demonstrate the knowledge and skills required to provide patients with optimal care. The program's aim is to promote professional development, lifelong learning and quality assurance for the public and medical community. However, physicians are not happy with the current structure of the program, claiming it to be time-consuming, expensive and ineffective for their practice. The lack of concrete evidence confirming the efficacy of MOC in improving knowledge and clinical outcomes causes many to question how this system can be improved to better serve practitioners and the public. In this commentary, we provide an overview of the current MOC situation for U.S. specialists and highlight the importance of increasing research to inform evidence-based changes that can be applied to clinical situations.
