Advanced Practice Nursing Model for Comprehensive Care With Chronic Illness: Model for Promoting Process EngagementCumbie, Sharon A. PhD, RN; Conley, Virginia M. PhD, RN, FNP,C; Burman, Mary E. PhD, RN, FNP,CAdvances in Nursing Science: January/February/March 2004 - Volume 27 - Issue 1 - p 70–80 Articles Abstract Author Information New models of providing care to chronically ill persons are needed that can facilitate a more integrative approach to patient care. The purposes of this article are to describe the utilization of a theory synthesis process for development of a client-focused approach for advanced practice nurse (APN) management of chronic illness and to present the Model for Promoting Process Engagement. The model was developed as a theory-driven intervention to address complexities of chronic illness care. This APN practice model is the direct result of the synthesis of a number of differing theoretical models developed by the authors in previous individual research endeavors. From the Fay W.
