Advanced practice nursing: unification through a common identity.

Despite the wide variety of advanced practice roles in nursing and the well-documented differences among them [Hamric, A. (2000). A definition of advanced nursing practice. In A. Hamric, J. Spross, & C. Hanson (Eds.), Advanced nursing practice: An integrative approach (pp. 53-73). Philadelphia, PA: W. B. Saunders], the authors suggest that nurses in these roles should adopt a common identity, that of an "advanced practice nurse" (APN). The authors outline the development of advanced practice nursing in Canada and the United States, tracking historical influences and highlighting current issues facing APNs. The authors explore elements that constitute the definable and describable core of advanced practice nursing-knowledge, education, scope of practice, regulatory issues, and outcomes. They conclude that adoption of a common identity for all advanced practice nursing roles may clarify role confusion (which is currently experienced within and outside the profession), reinforce links between knowledge development and nursing practice, and ensure that advanced nursing practice is responsive to the needs of society.
