The death of an 89-year-old woman on the roof of University of Pittsburgh Medical Center Montefiore is prompting several investigations, and the hospital could face fines, a change in its accreditation status, and a lawsuit from the woman's family. Pittsburgh police, the state Health Department, and the hospital itself will examine how the woman, who suffered from dementia and heart problems, was able to wander unnoticed from her 12th-floor room and go to the roof. Her body was found there by a maintenance worker. Within 45 days, UPMC is expected to issue a report and action plan to The Joint Commission.
