HF is a life-threatening condition in which the heart can no longer pump enough blood to the rest of the body. It is important for individuals with heart failure to closely monitor their symptoms, seek out medical attention when appropriate, and effectively self-manage their condition. However, people with HF are often frail, poor, and socially isolated. These factors may limit their ability to access clinic-based services and self-manage their condition. Research has shown that group health care visits with other HF patients and peer support for self-care behaviors are effective at improving heath care outcomes. This study will use an interactive voice response (IVR) system, which is a low-cost telephone system that allows calls to be made through a central 1-800 number, thereby eliminating the need to distribute home phone numbers or pay for long distance calls. Through the IVR system, participants will receive and provide peer support by sharing and discussing HF self-management techniques. The IVR system will also facilitate patient communication with care managers. This study will evaluate the effectiveness of the peer-to-peer IVR program in combination with group health care visits led by HF nurses at reducing hospitalization and death rates among HF patients. Participants will be drawn from a community health care system that primarily serves large numbers of racial minority and socioeconomically vulnerable people.
