Abstract
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.
