Brief Summary in Lay Language

For patients with heart failure, regular monitoring of health status to adjust treatment and avoid complications is a critical component of care. Telemedicine interventions that facilitate such monitoring have already led to positive care effects in other trials. The ProHerz app is a software application that supports guideline-based care. In combination with wearables, vital parameters are collected and evaluated, and the user is given information about his or her health status to enable better management. In order to make this care approach the norm, the app is to be listed as a digital health application (DiGA). By means of a clinical trial, positive health care effects are to be proven in accordance with the Digital Health Care Act (DVG). To test the feasibility, this preliminary study precedes the clinical evaluation trial in cooperation with the Nuremberg Hospital.

Brief Summary in Scientific Language

The aim of the single-center, national, exploratory trial is to investigate how an evaluation trail on the use of the ProHeart App can be conducted for a positive care effect according to the Digital Care Act (DVG) for patients with heart failure. The ProHerz App is a software application that supports guideline-based care.
It will be examined whether the selected measurement instruments of the study (such as standardised gait tests, patient questionnaires) provide indications of the care effects. In addition, it will be examined whether the study design can be implemented for an evaluation trial with regard to recruitment, data collection, drop-out rate and sample size. In addition, the usability of the ProHerz app will be evaluated.
