 Home telehealth is a general term used to describe the delivery of health care services to the patients home using audio, video, or other telecommunications technologies. Although home telehealth offers a number of theoretical advantages, few well-designed controlled clinical trials have been conducted to establish efficacy and cost benefit. Furthermore, projects to date have focused on special populations, e.g., heart failure or mental illnesses. Since home telehealth may hold the most promise for individuals dealing with multiple chronic illnesses, there is a need for population-based studies addressing the needs of patients in primary care settings.
