Background: Nurse practitioners (NPs), if utilized to their optimal potential, could play a key role in meeting the growing demand for primary care.
Purpose: The purpose of this study was to propose a comprehensive model for maximizing NP contributions to primary care which includes the factors affecting NP care and patient outcomes and explains their interrelated impact.
Method: We synthesized the results of the published literature to develop a model, which emphasizes NP scope of practice regulations, institutional policies, NP practice environment, and NP workforce outcomes as determinants of NP care and patient outcomes.
