No red flags were apparent when the Maine Board of Licensure in Medicine checked Dr. Jaroslav Jerry" Stulc's background in 2007. But within months of joining a hospital staff, the surgeon was accused of sexual misconduct. The hospital ... suspended him with pay. Then, while he was out, the hospital and medical board learned that Stulc previously had been suspended by a Kentucky hospital following allegations of sexual misconduct. Skirting federal rules, the Kentucky hospital hadn't reported his suspension or subsequent resignation to the nationwide database established for hospitals and medical boards to share information on physician misconduct. Instead, just before Stulc applied for his Maine license, he and the hospital had agreed that he would voluntarily resign. The hospital wouldn't mention the suspension ... to anyone who inquired. Such private agreements, along with legal loopholes and outright flouting of the law, are among the reasons the nationwide repository - the National Practitioner Data Bank - can leave patients and medical staff vulnerable, an Atlanta Journal-Constitution investigation found. Even when hospitals and medical boards file reports, they may classify violations in a way that conceals the scope of physician sexual misconduct. Because of such gaps, the AJC - in reviewing board orders, court records and news reports - found about 70 percent more physicians accused of sexual misconduct than the 466 classified as such in the public version of the data bank from 2010 to 2014.
