Enacting primary healthcare interprofessional collaboration: a multisite ethnography of nurse practitioner...

Interprofessional collaboration (IPC) is known to enhance patient outcomes and satisfaction. In primary healthcare (PHC), IPC aims to transform care provision and team functioning, but its implementation is challenging and has yielded mixed results. We aimed to describe the enactment of IPC in PHC settings, particularly as it relates to nurse practitioner (NP) integration. A multisite ethnography involving 6 Canadian PHC clinics was carried out. We conducted 330 hours of direct observation, 23 semi-structured interviews with PHC NPs, informal interviews with key PHC partners, and document analysis. IPC in PHC was found to rest on human and non-human actors that interact in complex ways. Organizational mandates and remuneration models, physical spaces and schedules played a decisive role in the enactment of IPC. Power structures embedded in certain designations (i.e., most responsible provider) or NPs' commitments to physicians' practices stood in contrast with the principles of IPC. NPs enacted various role to develop, enhance, and maintain IPC. Despite shifts in PHC provision, IPC remains poorly defined and precariously sustained.
