Utilizing Nurse Practitioners and Physician Assistants in Academic Emergency Departments Does Not Reduce Residents' Exposure to More Complex Patients

Background: Whether integration of nurse practitioners (NPs) and physician assistants (PAs) into academic emergency departments (EDs) affects emergency medicine (EM) resident clinical learning opportunities is unclear. Objective: We sought to compare EM resident exposure to more -complex patients, as well as patients undergoing Accreditation Council for Graduate Medical Education (ACGME)-required procedures, at nonpediatric academic EDs with lower, moderate, and higher levels of NP/PA utilization. Methods: In this cross-sectional study of National Hospital Ambulatory Medical Care Survey (NHAMCS) data for 2016-2020, nonpediatric academic EDs were classified into the following three groups based on the percentage of patients seen by an NP or PA: lower (<= 10%), moderate (10.1-30%), and higher (> 30%) NP/PA utilization. The proportion of EM resident-seen patients meeting previously established complex patient criteria was then determined for EDs at each level of NP/PA utilization. The proportion of EM resident-seen patients receiving certain ACGMErequired procedures was also determined. Survey analytic procedures and weighting as recommended by NHAMCS were used to calculate and compare proportions using 95% CIs. Results: The weighted 2016-2020 NHAMCS data sets represent 44,130,996 adult resident-seen patients presenting to nonpediatric academic EDs. The proportion of residentseen patients meeting complex patient criteria did not significantly differ for lower (43.2%; 95% CI 30.6-56.8%), moderate (41.7%; 95% CI 33.0-50.9%), or higher (38.9%; 95% CI 29.3-49.4%) NP/PA utilization EDs. The proportion of patients undergoing an ACGME-required procedure also did not significantly differ across level of NP/PA utilization. Conclusions: Higher levels of NP/PA utilization in nonpediatric academic EDs do not appear to reduce EM resident exposure to more -complex patients or ACGME-required procedures.
