More than 2,400 U.S. doctors have been sanctioned for sexually abusing their patients, according to a new report that, for the first time, surveyed records from all 50 states and reveals the nationwide scope of a problem that may be almost as far-reaching as the scandal involving Catholic priests. State medical boards, which oversee physicians, allowed more than half the sanctioned doctors to keep their licenses even after the accusations of sexual abuse were determined to be true, according to a yearlong investigation by The Atlanta Journal-Constitution. "We found a culture of secrecy," said Carrie Teegardin, a reporter on the paper's investigative team. Even after being convicted of sex crimes and losing their licenses, doctors are often able to reapply to practice again. The Journal-Constitution investigation began with a story about one Georgia doctor that led to efforts to document the problem nationwide. By combing through news reports, state medical board records and court files going back 16 years, the Journal-Constitution's reporters compiled a list of physicians who were either convicted in criminal cases or disciplined by state medical boards. Many of the doctors were accused by large numbers of their patients, in most cases females being seen by male doctors. "One thing we found that was shocking to us is some of these doctors are the most prolific sex offenders in the country, with hundreds and, in some cases, thousands of victims," Teegardin said.
