The Emergency Severity Index (ESI) is a new five-level triage instrument. The objective of this study was to determine whether there is an association between ESI triage status and short-term survival. ⋯ The ESI triage status is associated with six-month survival. Patients with the highest three triage groups experienced decreased survival during the follow-up period, whereas all patients in the two lowest triage strata survived at least six months.

As a method to control patient flow to overburdened hospitals, effective emergency medical services (EMS) systems provide policies for ambulance diversion. The Maryland state EMS system supports two types of alert for general hospital use: red alert, aimed at limiting the delivery of patients who may require intensive care unit (ICU) admission, and yellow alert, aimed at preventing further overload of already overtaxed emergency departments (EDs). ⋯ The ED diversion policy has some limited effect in preventing further patient volume in urban and suburban areas, but has virtually no impact in rural areas. However, an ICU diversion policy diverts patients of all acuities uniformly and inordinately diverts patients not likely to require ICU admissions while having only minimal impact on patients who do require ICU resources. The impact of red alert is uniform in all geographic areas. The impact and efficacy of ambulance diversion policies should be evaluated to ensure they are having the intended effect. While perhaps initially effective, the impact of alert policies may change over time.
