Since at least April 2021, the Montana medical licensing board has had evidence, including thousands of pages of patient files and medical reviews, that Dr. Thomas C. Weiner, a popular Helena oncologist, had hurt and potentially killed patients, ProPublica and Montana Free Press have learned. Yet in that time, the board renewed his medical license twice.
Weiner directed the cancer center at St. Peters Health for 24 years before he was fired in 2020 and accused of overprescribing narcotics, treating people who didnt have cancer with chemotherapy and providing substandard care. Weiner, who has denied the allegations, was the subject of a December ProPublica investigation, which revealed a documented trail of patient harm and at least 10 suspicious deaths. Many of the records cited in the story had been in the medical boards custody for nearly four years, St. Peters recently confirmed.
The Board of Medical Examiners renewed Weiners medical license in March 2023 and this month, authorizing him to treat patients and prescribe drugs. While lawyers for the state agency that oversees the medical board collected records from the hospital under subpoena, including medical reviews that criticized Weiners care, that inquiry languished at the staff level, according to one current and one former board member. Its unclear why Weiners case was not elevated to the governor-appointed board members.
Sam Loveridge, a spokesperson for the Department of Labor and Industry, the boards umbrella agency, did not answer a list of emailed questions, including whether the records provided by the hospital were reviewed by members of the board.
Kathleen Abke, a lawyer representing St. Peters, told ProPublica and Montana Free Press that the hospital initially surrendered to the licensing board 160,000 pages of documents relating to the care of 64 patients; the state received those records in early 2021, just months after Weiner was fired.
