The latest Clinical Decisions asks about a 55-year-old physician who practices internal medicine with a strong subspecialty in endocrinology. He holds time-unlimited certificates from the American Board of Internal Medicine (ABIM) in both internal medicine and endocrinology, known as “grandfather” status because recertification is not required as it is for younger physicians. Should he voluntarily recertify, or is it not relevant to his practice? We asked you to read the argument presented for each side and comment about your choice. View those comments now. Earlier Clinical Decisions on the management of incidental hepatitis C virus infection, skin and soft-tissue infection, Type 2 diabetes, stable coronary disease, and the treatment of mild persistent asthma are also available at NEJM.org.
