Management of heart failure is usually multidisciplinary and collaboration between stakeholders in a dedicated HI network like the HerzMobil Tirol can be supported by a mHealth-based telemedicine approach. The aim is to gain insights through textual analysis of collaboration notes that might trigger further developments and improvements of the HI network. A reusable pipeline for textual analysis of unstructured textual notes was implemented using the open source analytics software KNIME. After preprocessing, a keyword analysis was performed resulting in a classification of all notes in predefined categories.

Results: Medical and organizational issues dominate the communication with health status and therapy aspects as well as clinical treatment, discharge letter and home visits. Beside aspects of data transmission and mobile phone, technological issues are minor topics during the collaboration. It is possible to gain new insights with respect to technology like additional control Apps for mobile phone settings and to the HI network like clinical experts and technical help desk involvement.
