In 2019, heart failure was the most frequent single diagnosis for in-patient stays in German hospitals . As part of the therapy, heart failure patients need to continuously monitor their medication intake and their vital parameters such as blood pressure, oxygen saturation, weight and pulse . This enables early countermeasures in the event of a deterioration of the health condition or adjustment of the medication. One way of assisting patients with this process is through the use of smartphone-based health applications. These applications support patients by enabling them to self-monitor relevant health data, and track their medication intake. Moreover, they offer the possibility to provide psychological support to patients and to increase health literacy through educational content .
Generally, mobile health solutions have a beneficial impact on chronic disease management. In the context of heart failure treatment, mobile applications indicate a high potential to effectively support patients during their therapy. [4, 5]. One important factor for the adoption of and engagement with mobile health applications is motivation. Motivated users are more likely to use and sustain their app usage . Several studies already identified a set of potential factors increasing the motivation and therefore the engagement and adherence of users [7–9]. However, little research has been conducted on the actual implementation of these factors and their impact on already existing digital health applications.
Therefore, the aim of this research is to collect motivational factors for the use of smartphonebased health applications and integrate them in a user interface concept for an already existing digital health application for heart failure patients. This concept is then to be implemented as a prototype and evaluated.
This thesis is conducted in cooperation with ProCarement GmbH, which has developed the ProHerz app to support heart failure patients during their therapy. The app enables the user to monitor relevant health data, track medication intake, manage medical documentation and be in personal contact with medical professionals.
