This paper describes an on-going field study to develop an eHealth and mHealth system to accurately monitor heart failure and guide appropriate actions. We describe the foundations of the tool to nurture appropriate self-care behaviors along with the theoretical development to serve as the foundation. The on-going research and research design is explained in detail and implications are discussed. Preliminary data collection and descriptive analysis are presented and on-going research plans are discussed. The research will develop and test the impact of the system on the quality of care for patients, the care processes for caregivers and presents implications for the cost of care. The research is guided by the hypothesis that the mHealth tool will impact the health care provider by reducing emergency department visits and same cause readmissions – both factors that significantly impact the cost and quality of care.
