A small victory for patient safety has come in west Texas, where a jury took less than an hour to acquit Anne Mitchell, a nurse who had been indicted on felony charges for reporting a doctor to the state medical board whom she thought was endangering patients with poor care. The charge against Ms. Mitchell was "misuse of official information," because she had used confidential patient records in her report to the medical board. The sheriff who investigated the case and spurred the indictment was a friend and business partner of the doctor.
