ABSTRACT
BACKGROUND: Children's National Health Systems pediatric emergency department (ED), is a level 1 trauma center in Washington, DC, which treats over 90 000 patients annually. Approximately 50% of arriving patients are triaged as low acuity, Emergency Severity Index level 4 or 5. With limited space and resources, these patients are treated inefficiently, with average delays from arrival to provider time of 1.3 hours and length of stays (LOS) close to 2.5 hours. OBJECTIVES: In July 2016, Children's National Health Systems ED initiated a focused approach to improve both patient flow and experience for these low-acuity patients. METHODS: We assembled a multidisciplinary ED-based task force. The quality improvement initiative began in January 2017 and consisted of 4 steps: (1) front-end space redesign; (2) implementation of a new front-end patient triage and assessment process; (3) increased doctor and nurse staffing; and (4) dissemination of data updates to reinforce awareness and adherence to workflow. Our process outcomes were arrival-to-provider time and LOS for low-acuity patients. Our balancing measures were the rate of return to the ED within 72 hours and arrival to provider times for high-acuity patients. We used statistical process control methodology to measure the effects of our interventions over time. We performed a secondary analysis to measure the response of wait times to total daily volume comparing preintervention to postintervention. RESULTS: We decreased the LOS by 11 minutes (9%) and arrival to MD times 21 minutes (35%) for the same period 1 year apart.
