Officials at Olive View-UCLA Medical Center acknowledged that they had launched an investigation into possible leaks of patient information and had warned staff not to speak to the media after reports about allegations of substandard care in the hospital's neonatal intensive care unit. Carolyn Rhee, the hospital's chief executive, said Los Angeles County Health Department policy is "that our employees not talk directly to the media." The investigation into whether confidential patient information had been breached got underway after Los Angeles County officials launched an inquiry into the anonymous complaints made to an accreditation agency, the Los Angeles Times reports.
