Pennsylvania-based Aria Health executives said that staff members did not violate protocols in dealing with Joaquin Rivera, the 63-year-old man who died while waiting for care in the health system's Frankford hospital, but added that protocols would be changed in the hope of avoiding another waiting-room death. Aria officials think Rivera died 11 minutes after walking into the hospital. The hospital was not alerted to his death until another person in the waiting room reported that someone had taken Rivera's watch.
