The Nurse Practitioner (NP) role possesses a high value to Fee-For-Service (FFS) practices in the primary healthcare system. A case study evaluation of the NP roles in three FFS clinics showed positive impacts on patient satisfaction and physician experience. Physicians' FFS expenditures increased 12% after the NP implementation. Although NP services could provide cost savings to the acute care system, financial sustainability of the NP role in FFS practice remains a challenge.
