The state Medical Examining Board on Tuesday reprimanded a Litchfield physician for his abuse of alcohol and violating professional boundaries with an office employee. In unrelated cases Tuesday, the board also fined two doctors and a physician assistant and reprimanded a Rhode Island doctor who has a license to practice in Connecticut. In the Litchfield case, Dr. James O’Halloran III was also reprimanded for prescribing controlled substances for five patients without adequate documentation or safeguards, according to a consent order approved by the board Tuesday. O’Halloran works full-time for the state Department of Correction, but these actions took place in his private practice, the consent order said. In 2014, he had a personal relationship with an employee and his prescription pad was stolen, David Tilles, a staff attorney for the state Department of Public Health, told the board.
