Models of care with advanced practice nurses in the emergency department: A scoping review

Emergency departments play a critical role in healthcare systems internationally. Visits for emergency care continue to increase, related to poor access to primary care, the COVID-19 pandemic, and health human resource issues. International literature shows similar stressors in the emergency department. Extended wait times to see health providers lead to poor outcomes, and innovative models of care are needed to address emergency department overcrowding and to meet the needs of patients. Advanced practice nurses have the expertise and scope of practice to optimize and address primary and acute care needs and could be further integrated into the emergency healthcare systems. It is unclear what and how advanced practice nurses are functioning in emergency departments to improve patient and organization outcomes. This scoping review was a comprehensive search of MEDLINE, EMCARE, EMBASE, Cumulative Index to Nursing and Allied Health Literature, and gray literature. Authors developed inclusion and exclusion criteria, performed title and abstract screening, and full text screening using review software. Data about models of care with advanced practice nurses were extracted and organized to understand patient, provider, and organizational outcomes. We also extracted information about the development and implementation of roles. Of the 6780 records identified, 76 met inclusion criteria. Emergency department models of care, mainly using nurse practitioners, include fast-track, generalized emergency, minor injury, orthopedics, pediatrics, geriatrics, specific populations, and triage. Reported patient outcomes include improvement in key metrics specific to emergency departments, such as total length of stay, wait times to be seen by a provider, left without being seen rates, treatment for pain, costs, and resource use. When comparing nurse practitioners to other providers, outcomes were similar or better for patient and organizational outcomes. Various models of care utilizing advanced practice nurses in emergency departments are present internationally and information about how they are developed, integrated, and utilized provides practical information to support and sustain new roles. There is an opportunity to expand the use of these roles into emergency departments as the nurse practitioner scope of practice grows. Given the current crisis across healthcare systems, there is need for innovation, and improving delivery of emergency services with these advanced pra
