Clinical Trial TIM-HF

The TIM-HF study design (multicenter, randomized, prospective, open, parallel, controlled) corresponds to international standards. It is one of the largest randomized clinical telemedicine trials on chronic heart failure. The aim of the study is to evaluate the medical and economic benefits of telemedical care for patients with cardiac insufficiency. This should also create the prerequisites for an application for inclusion in the catalog of services of the statutory health insurance funds ("telemedicine on prescription").

After the first results were available, it was possible to demonstrate within the framework of the PfH project that telemedicine-cared patients significantly improved their quality of life. In high-risk patients, even lower mortality could be achieved. In non-depressed patients with adequate cardiac output who had been treated in hospital for decompensation in the previous two years, the mortality rate from cardiovascular diseases was halved compared with the control group. For the first time, TIM-HF defines precisely those patient groups with chronic heart failure who benefit most from telemedical care.

Telemedical care met with great acceptance among patients and led to a higher quality of life. This could be statistically proven through regular standardized patient surveys. In addition to the high feeling of security, the patients were able to stay in their home environment in the familiar social environment. The care was also seen positively by the patients in rural areas, who otherwise had to make long journeys to the treating doctor.
