Web-based Internet telemedicine management of patients with heart failure.
An Internet-based store- and -retrieval telemedicine system to communicate between patients and their healthcare provider was tested . The system requires no specialized equipment , is Web-based , and allows frequent surveillance of the health status of the patients with heart failure ( HF ) . Thirty six patients were recruited to evaluate a Web-based telemedicine system for reducing care encounters . Eighteen patients were r and omized to the telemedicine arm ( group T ) , and 18 were given usual clinical care ( group C ) in our HF center . Patients in group T reported three times weekly via a secure Internet site for telemedicine intervention . We studied patients with HF with New York Heart Association ( NYHA ) class 2 to 4 with hospitalization within past 6 months . Mean age was 56.1 + /- 12.6 years ( 66.7 % male ; 66.7 % Caucasian , 27.8 % African American , and 5.6 % Hispanic ) .  Mean ejection fraction ( EF ) was 23.9 % + /- 17.6 % in group T and 26.6 % + /- 16.4 % in group C. Over an 8-month period , unscheduled ( group T-3 ; group C-5 ) , and scheduled clinic visits ( group T-11 , group C-7 ) were similar ( p = NS ) ; one group T patient was transplanted , one group C patient died . Total hospital days were lower with group T ( 44 days ) compared to group C ( 133 days ) , p < 0.05 . An Internet-based telemedicine system was able to closely monitor patients with HF . Surveillance through Internet-based telemedicine result ed in less hospitalization compared to control patients . This system may be helpful in reducing the cost of HF patient care
