Does an ED flow coordinator improve patient throughput?

INTRODUCTION

At our urban academic medical center, efforts to alleviate ED overcrowding have included the implementation of a "fast track" area, increasing the ED size, using hallway beds, and ambulance diversion. In October 2012, we began the first steps of a process that created a system in which the admission process involves equal amounts of pushing and pulling to achieve the balance necessary to accomplish optimal outcomes. The foundation of the initiative was based on the use of a BSN-educated emergency nurse as a flow coordinator; a position specifically empowered to affect patient throughput in the emergency department.

METHODS

A determination of quality improvement was obtained by the local institutional review board for a retrospective analysis of all ED patient encounters 1 year before and 1 year after the implementation of the ED flow coordinator position. All patient encounters were included for consideration and calculation; no encounters were excluded.

RESULTS

The flow coordinator program decreased length of stay by 87.6 minutes (P=.001) and lowered LWBS rate by 1.5% (P=.002). Monthly hospital diversion decreased from 93 hours to 43.3 hours (P=.008).

DISCUSSION

Investing in a flow coordinator program can generate improvements to patient flow and can yield significant financial returns for the hospital. A decrease in diversion by an average of 49.8 hours per month translates to an annual decrease of nearly $20 million in lost potential charges. A decrease in the LWBS rate by 1.5% (31% relative decrease) per month translates to an annual decrease in lost potential charges of more than $5 million. Our research shows that an ED flow coordinator, when supported by departmental and hospital leadership, can yield significant results in a large academic medical center and that the program is able to produce an effective return on investment.
