Association Between Ambulance Diversion and Survival Among Patients with Acute Myocardial Infarction

Vol. XIV, No. 7
October 2011

Emergency department (ED) crowding has become increasingly common in the United States. When EDs are overextended or lack the resources to treat different types of patients, they may initiate ambulance diversion, which temporarily closes the ED to ambulance traffic. For patients suffering from acute, time-sensitive conditions, diversion can cause delays in treatment and potentially worsen the the prognosis. HCFO-funded work by Yu-Chu Shen, Ph.D., of the Naval Postgraduate School, and Renee Hsia, M.D., M.Sc., of the University of California San Francisco, examined the impact of ambulance diversion on patient outcomes for patients suffering from acute myocardial infarction (AMI).
