Clinical nurse specialist: role restructuring to advanced practice registered nurse.

This article recognizes challenges facing the traditional clinical nurse specialist (CNS) role and supports the merger of the nurse practitioner (NP) and the CNS into a hybrid advanced practice registered nurse (APRN). A historical review of each role is presented, with justification for role merger. The focus of the article is to present a personal account of this author's successful reengineering of a traditional cardiovascular CNS role to conform to a new state and institutional APRN model and ultimately to better serve a population of post-myocardial infarction patients.
