When East Cleveland's emergency medical squad gets called to treat a man with a severe nosebleed, it's a pretty run-of-the-mill case. The patient walks woozily out to the ambulance from a tan house on a tree-lined street. Anthony Savoy, the head medic, calls ahead to University Hospitals, which has the closest emergency room. Savoy wants to make sure the ER has space for the patient. The man gets in that day, but it was by no means guaranteed. For years, it's been common practice for University Hospitals to switch its status to diversion.
