As docs grow older, hospitals begin requiring proof they're still fit

A distinguished vascular specialist in his 80s performs surgery, then goes on vacation, forgetting he has patients in the hospital; one subsequently dies because no doctor was overseeing his care. An internist who suffered a stroke gets lost going from one exam room to another in his own office. A beloved general surgeon with Alzheimer's disease continues to assist in operations because hospital officials don't have the heart to tell him to retire. These real-life examples, provided by an expert who evaluates impaired physicians, exemplify an emotionally charged issue that is attracting the attention of patient safety experts and hospital administrators: how to ensure that older doctors are competent to treat patients.
