New forms of care for complex chronic diseases require substantial efforts in the collection, storage, and analysis of privacy sensible medical data. Additionally, providing practical support for those who coordinate the actual care management process within a diversified network of regional service providers is beneficial. In this paper, we present a follow-up with the current status, lessons learned, and preliminary results of the IT infrastructure in project STROKE OWL. The project aims at a comprehensive implementation of cross-sector care management for stroke patients. Patients are accompanied in their recovery by stroke pilots, who use a specially designed tablet app for the piloting. It is shown how the tablet app uses receiver-oriented encryption to support the piloting process while ensuring privacy.
