Sirens and speeding ambulances are the symbols of emergency care. The basic idea is that the sooner we get seriously injured trauma patients to the hospital, the bigger the chance of their survival. The first 60 minutes after an accident are known as the “golden hour”. Getting the patient to the hospital in this golden hour is claimed to be critical. This is intuitive. But, unfortunately, this claim is not really supported by a whole lot of empirical data. In fact, the authors (who are ER physicians) of a recent Slate story discuss the statistical evidence supporting the myth of the golden hour. They discuss a recent study published in the Annals of Emergency Medicine that finds no support for the importance of extra speed (http://www.slate.com/id/2253638/).
But why then, are the ambulances driving so fast? From an operations management perspective, two explanations come to mind. First, the fact that an extra couple of minutes do not matter much in predicting patient survival rate does, of course, not imply that the driver can stop at the next Starbucks… Second, there might be an alternative explanation for the speeding ambulance. Let’s call it the NY cab driver syndrome: The faster you drive, the sooner you will be available for the next trip. After all, it is all about productivity.
