In this paper, we examine requirements, show potential user interfaces and describe a prototypical development for a Pathway Navigator App that guides the patient through healthcare episodes. Our use case is a fictional patient requiring surgery for a hip total endoprosthesis. Fundamental is the provision of appointment information and the option to contact the healthcare provider for rescheduling. This implied an architecture which was more complicated than expected. We realized an HL7 interface for appointment data from hospital information systems; no comparable standard was found for GP IT systems. The future Swiss Electronic Patient Dossier could enhance the integration of the Path App within a broader health-IT ecosystem.
