Theory of the Evolution of Nurse Practitioner Practice

Abstract

Aim: To determine the nurse practitioner's perception of scope of practice and understanding of changes to practice over time. Background: A great deal of research about nurse practitioners has been conducted related to such things as role clarity, transition, or preparedness to practice and job satisfaction. Conceptual models of nurse practitioner practice have been developed to highlight practice processes, interprofessional relationships and more. However, none of this literature addresses nurse practitioner's perception of scope of practice, the impact of their changing practice experiences and how the understanding of their practice changes over time. Methods: This grounded theory study was undertaken in Ontario, Canada, with interviews of primary health care nurse practitioners which resulted in the Theory of the Evolution of Nurse Practitioner Practice. Conclusion: Within this theory, scope of practice is defined as nurse practitioners working to their maximum potential.  There are both intrinsic and extrinsic elements which render maximum practice potential a fluid and changing state.
