Integrating Mobile Devices Data into a MeDIC Inside a Hospital – Lessons Learned

Introduction: Within a study investigating the potential of data from mobile devices to identify patients with heart failure at risk for clinical worsening we implemented standard-based integration of mobile data into a Medical Data Integration Center (MeDIC) inside a university clinic. State of the art: We identified four different integration approaches from the literature. Concept: Data is processed live, i.e. no bulk export. Implementation: We enrolled 23 patients and integrated 24817 FHIR messages with mobile data. Lessons learned: Integrating mobile device data into a university hospital is complex. We derived a list of questions to consider in planning data integration from mobile devices in similar research projects, emphasizing the importance of clarification of requirements and consideration of implementation details.
