The state Medical Examining Board has disciplined three doctors and fined them a total of $25,500 for lapses in the care of patients. The board, meeting in Hartford on July 16, reprimanded Dr. William Guinan of South Windsor and fined him $10,000 for failing to perform PAP smears on one of his patients for six years after having diagnosed her with cancer in 2009, state records show. Guinan surgically removed the woman’s uterus and one ovary to treat the cancer, a consent order he agreed to said. In 2015, she was diagnosed with Stage III metastatic vaginal cancer. The order said Guinan had failed to adequately document a treatment plan for her in 2009, failed to instruct the patient about her long-term cancer risks and failed to review her medical history during exams over the next six years.
