INTRODUCTION/OBJECTIVES: Nurse practitioners (NPs) improve access to care in community-based primary care. Determining an appropriate workload for NPs is complex. The number of patients seen by NPs represents an important consideration. We sought to determine the feasibility, acceptability and appropriateness of implementing the online NP workload measurement index (NP-WI). METHODS: Feasibility study supported by the Theoretical Framework of Acceptability, conducted across 3 health regions in Québec, Canada. Data were collected from January to July 2024 using the online NP-WI ( RESULTS: NPs indicated that the NP-WI was easy to use. Acceptability scores were positively rated. Daily data entry took 5 to 7 min to complete. NPs deemed a 4-week collection period sufficient to capture a representative workload sample. The NP-WI captured patient, provider and organizational characteristics and the number of patients seen by NPs. CONCLUSIONS: NP-WI implementation was feasible. The instrument can support healthcare workforce planning with more adequate estimations of NP workload in community-based primary care, and provide greater equity in resource allocation and distribution of NP workload.
