 Congestive heart failure CHF is one of the most common reasons for hospitalization in patients aged 65 years and older. Many hospitalizations for CHF are potentially preventable if the warning signs of decompensation are recognized and treated before the situation becomes emergent. Home-based intervention programs have reduced unplanned readmission rates for patients with CHF by up to 50 percent. Using advanced telecommunications technologies it is now possible to provide greatly improved access and availability of services in a more timely and cost effective manner directly to patients homes. Although telehealth offers a number of theoretical advantages, few empirical studies have compared telehealth to traditional delivery modes, and virtually no studies have compared the effectiveness of alternative telehealth applications.
