Malpractice findings are increasingly easy to find on websites maintained by medical boards in 19 states, but not in Minnesota, where regulators have resisted efforts to make more information available to people who want to check into the backgrounds of their doctors. The Minnesota Board of Medical Practice also doesn't disclose whether doctors have been disciplined by regulators in other states or lost their privileges to work in hospitals and other facilities for surgical mistakes and other problems—information provided in 13 other states.
