Paired analysis of ED efficiency for low-acuity children treated by PAs and pediatricians.

OBJECTIVE:To determine if there was a clinically important difference (15 minutes or more) in length of stay (LOS) for low-acuity pediatric ED patients treated by PAs compared with those treated by pediatricians. METHODS:Between July 2017 and February 2020, shifts were identified that had shared PA and pediatrician staffing in the low-acuity care area for a large, urban ED. LOS was collected for every patient during the 6 hours of overlap for each shift. Using a paired analysis, we calculated the difference in mean LOS for these shifts. RESULTS:Mean shift LOS for children seen by PAs (160.1 minutes, SD: 48.6) was 10.1 minutes longer (95% CI: 6.1, 14.1) than mean shift LOS for children seen by pediatricians (150 minutes, SD: 47.3). CONCLUSIONS:No clinically important difference in LOS was found for low-acuity children treated by PAs compared with those treated by pediatricians in a large, urban ED.
