A former patient filed a proposed class-action lawsuit April 17 against San Diego-based Sharp HealthCare and one of its hospitals after motion-activated cameras placed in operating rooms filmed more than 1,800 patients during surgeries without their consent. Sharp HealthCare officials said the cameras were installed on anesthesia carts used in the operating rooms at La Mesa, Calif.-based Sharp Grossmont Hospital’s Women’s Health Center as part of an investigation into whether an employee was stealing drugs.
