Telemedical Interventional Management in Heart Failure II (TIM-HF2)

Chronic heart failure is a widespread disease that currently affects about 1.2 million patients in Germany. With approximately 450,000 hospitalizations in 2016, it represents the most frequent reason for hospitalization. The outcome of this is the enormous charging of costs for care on these patients from the health and care insurance providers which makes more than three billion euros p.a. (Statistisches Bundesamt 2017)

In a controlled, prospective, multicentre, randomized, controlled clinical trial TIM-HF II (NCT01878630, DRKS00010239) the non-inferiority of a new ambulatory care model for underdeveloped rural area without resident cardiologists in patients with chronic heart failure (CHF) compared to regions with practicing cardiologists regarding medical health and economic effectiveness will be tested.

Primary endpoint is "Percentage of days lost due to unplanned cardiovascular (CV) hospitalization or due to death for any reason during the individual follow-up time”.

1,538 patients were recruited from metropolitan areas with more than 200,000 inhabitants and/or with a medical University and in rural areas in Germany.
