Objectives: We will evaluate the impact of extending the reach of HITCM by incorporating a protocol-driven model for improved monitoring and self-management support by a CarePartner (CP). CPs will be adult children or friends living outside the patient's home who are willing to play a structured role to support self-care. The specific aims of the trial are: (1) to determine whether an intervention that uses automated patient monitoring and behavior change calls with follow-up to HF patients' care manager and CP (HITCM+CP) improves key patient-centered outcomes relative to a system that only uses the same technology to support patients' care management (HITCM-only). Outcomes of interest include patients' health-related quality of life, mental health, health service use, and mortality risk; (2) to evaluate the impact of HITCM+CP on patients' self-care behaviors compared to HITCM-only; and (3) to determine whether the intervention increases the quality and quantity of support for HF patients' self-care compared to HITCM-only.
