This document discusses an integrated clinical engagement model for personal health records (PHRs). It describes key drivers for this model including efforts to increase efficiency, wellness, medical management, and consumer experience. The model includes a clinical data repository that integrates various types of patient data. Challenges include a lack of standards for transferring all types of PHR data between health plans and representing elements such as alerts and physiological information. Alignment with existing standards and expanding PHR data domains are suggested for moving forward.
