Mayo Boulevard, Phoenix, AZ 85054 , Abstract—Background: Although the use of a physician INTRODUCTION and nurse team at triage has been shown to improve emer- gency department (ED) throughput, the mechanism(s) by Improving emergency department (ED) throughput is an which these improvements occur is less clear. Objectives: 1) important area for hospital process improvement. Poor To describe the effect of a Rapid Medical Assessment (RMA) ED throughput has been associated with increased 28- team on ED length of stay (LOS) and rate of left without being day mortality from pneumonia, delays to percutaneous seen (LWBS); 2) To estimate the effect of RMA on different groups of patients. Methods: For Objective 1, we compared coronary intervention in patients with acute myocardial LOS and LWBS on dates when we utilized RMA to compara- infarction, adverse cardiovascular outcomes in patients ble dates when we did not.
