The authors examined ambulance diversion logs from 26 California counties between 2001 and 2011 involving Medicare patients who had suffered heart attacks. They compared diversion time between hospitals serving a high volume of Black patients and other hospitals. The data showed that patients were more often diverted from hospitals with a large percentage of Black patients due to emergency room overcrowding. This can result in significant delays in treatment that produce disparate results in cardiac care and long-term survival prospects, according to the authors.
Renee Hsia, professor of emergency medicine and health policy at the University of California, San Francisco, states that “we have definitive evidence that minority-serving hospitals, or hospitals that serve a high proportion of Black patients, tend to experience higher levels of emergency department crowding.”
