BackgroundMost pediatric ED visits are for nonemergent problems. Physician assistants are well trained to manage these patients; however, their effect on patient flow in a pediatric ED is unknown.ObjectivesTo compare the effect on key pediatric ED efficiency indicators of extending physician coverage versus adding PAs with equivalent incremental costs.MethodsWe used discrete event simulation modeling to compare the effect of additional physician coverage versus adding PAs on wait time, length of stay (LOS), and patients leaving without being seen.ResultsSimulation of extended physician coverage reduced wait times, LOS, and rates of leaving without being seen across acuity levels. Adding PAs reduced wait times and LOS for high-acuity visits, and slightly increased the LOS for low-acuity visits.ConclusionsWith restricted autonomy, PAs mainly benefitted the high-acuity patients. Increasing the level of PA autonomy was critical in broadening the effect of PAs to all acuity levels.
