Effect of Paramedics in Emergency Department Triage on Ambulance Patient Offload Times

Abstract

Background: Emergency Department (ED) overcrowding limits patient care in the prehospital and hospital system. A program was implemented to decrease the time to patient handoff from EMS arrival to ED staff, also known as the delivery interval and total turnaround interval. Paramedics were added to the ED ambulance triage staff to receive verbal reports and perform certain tasks done traditionally by nurses. We hypothesized adding paramedics to the ED triage process would reduce delivery interval times and total turnaround times. Methods: This was a retrospective observational study comparing delivery and turnaround intervals for patients brought to the ED by ambulance, before and after the addition of a paramedic in triage. The study period included all adult ED patients brought in by ambulance between 11 AM and 11 PM. Pediatric patients (<21 years old), direct-to-inpatient interfacility transfers, and critical patients requiring immediate care in the resuscitation area and thus bypassing normal triage processes were excluded. The data was analyzed with two-sample t-tests with a confidence interval of a = 0.05. Results: Delivery interval pre-implementation of the program was 15:48 minutes (95% CI [15:28, 16:09]) compared to 14:04 minutes (95% CI [13:44, 14:25]) post-implementation. The mean turnaround interval pre-implementation was 35:21 minutes (95% CI [35:01, 35:42]) and 36:04 minutes (95% CI [35:40, 36:29]) post-implementation. The mean difference for the delivery interval was shortened by 01:44 minutes (p<0.0001; 95% CI [01:15, 02:13]). The mean turnaround interval increased by 00:43 seconds (p<0.01; 95% CI [00:11, 01:16]). Conclusion: Staffing a paramedic in ED triage decreased delivery interval by 1:44 minutes but did not affect ambulance turnaround times. Further research is needed to determine if the decrease in delivery interval improved patient outcomes and ways to translate the time saved in the delivery interval to total turnaround times.
