RESUMEN
INTRODUCTION: The pediatric nurse practitioner (PNP) workforce was designed to improve child health equity. We aimed to systematically review the evidence on facilitators and barriers to PNP practice. METHOD: We included empirical studies on PNP practice in the United States and excluded studies with non-identifiable PNP data. We applied Joanna Briggs Institute tools to appraise studies and applied critical interpretive synthesis principles to synthesize. RESULTS: The final sample is 26 studies, mostly published before 2013 and observational. Prescriptive privileges, training program availability, organizational climate, and telehealth are facilitators. Mandated physician supervision, reduced pediatric curricula, geographically disparate training programs, and poor data infrastructure are barriers. The sample is limited by a moderate to high risk of bias. DISCUSSION: Evidence suggests modifiable factors impact PNP practice and could have important implications for child health equity. We offer a theoretical model to guide robust research studying the PNP workforce and health equity.
