Stanislaus, San Joaquin and Fresno have the highest emergency room visits per capita among urban counties in California, according to a study released Tuesday.
Hospital emergency rooms in those counties receive large numbers of patients with medical conditions that can be treated in a doctors office or clinic, says the Public Policy Institute study "Emergency Department Care in California: Who Uses It and Why?" The study sheds light on the troubling health care issues in the San Joaquin Valley, where counties suffer from high unemployment, fewer doctors and a large percentage of residents who are uninsured.
