Improving emergency department flow by introducing a simple time out moment (The TRAFFIC LIGHT study)

Background and importance: Long waiting times in the emergency department (ED) is an increasing problem in the recent years and is expected to become an even bigger problem in the future
Objective: We aimed to test the hypothesis whether increasing awareness of the time lapse with the treating physician, 2 hours after patient arrival, can reduce long patient turnaround time (TAT).
Method: In this prospective single-center cohort study we compared and analyzed patient TAT in the ED before and after implementation of a so called ‘traffic light’ moment 2 hours after patient arrival. At this ‘traffic light” moment a team member contacted the treating physician to increased awareness over the time lapse. Difference in percentage of patients who stayed more than 4 hours in the ED before and after intervention was the primary outcome
Results: Between October 2nd 2021 and January 2nd,2022 1494 patients were included for primary outcome analysis. A total of 419 patients (n=740, 56.6%) had a TAT of less than 4 hour in the ED before intervention, compared to 497 (n=754, 65.9%) after intervention (p <0.001). Median time spent in de ED before intervention was 3:40 (IQR 2:24 – 5:04) compared to 3:15 (IQR 2:03 – 4:38) after intervention (p<0.001).
Conclusion: This simple and low-cost intervention reduces the ED length of stay significantly. Although multiple interventions will be required to ensure less patients spending more than 4-hours in the ED, a ‘traffic light’ moment can be a simple and an effective tool.
