Improving emergency department flow through Rapid Medical Evaluation unit.

Area of Science:

• Emergency Medicine
• Healthcare Management
• Quality Improvement

Background:

• Academic hospitals face increasing emergency department (ED) patient volumes without commensurate resource increases.
• Rising patient volumes lead to significant increases in wait times, particularly for lower acuity patients.
• Lower acuity patients disproportionately contribute to ED congestion, impacting overall care quality and resource utilization.

Purpose of the Study:

• To evaluate a quality improvement initiative aimed at reducing wait times for lower acuity patients in the ED.
• To assess the effectiveness of a newly created Rapid Medical Evaluation (RME) unit in streamlining care for these patients.
• To determine if improvements in lower acuity patient care impact wait times for higher acuity patients.

Main Methods:

• Retrospective evaluation of a quality improvement initiative involving the creation of an RME unit.
• Re-purposing existing resources and re-assigning one physician and one nurse to the RME unit.
• Measurement of physician initial assessment (PIA) and total length of stay (LOS) times for various patient groups across three 3-month periods.

Main Results:

• The RME unit demonstrated significant reductions in median PIA times (98min to 70min) and LOS times (165min to 130min) for lower acuity patients.
• Weekly measurements showed special cause variation, indicating positive impact across targeted patient groups.
• Wait times for all lower acuity patients remained low despite increasing ED visits, and higher acuity patient wait times were not adversely affected.

Conclusions:

• Re-purposing a fraction of existing staff and resources for a dedicated lower acuity pathway effectively streamlines care and decreases ED wait times.
• The RME model, developed through frontline staff involvement and PDSA cycles, is a replicable solution for other academic medical centers.
• Incremental improvements and continuous feedback are key to successfully managing ED congestion and enhancing patient flow.
