A business process model of the main use case for exchange of prescription content in the eHealth Digital Service Infrastructure is created and analyzed. The novelty in this approach is the proposed encoding of the basic dataset in a Quick Response (QR) code in terms of an XML scheme that is independent of clinical models or proprietary database structures. It allows to inverse the dataflow control in the chain of message exchanges between Dispenser and National Contact Points. The proposed inversion of control positions the citizen with the QR code of the prescription in the center of that chain of message exchanges between the main actors of the business process. The independent format of content representation in the QR code allows the actors in the message exchange to auto-populate data in their registers when the medicine is dispensed. Initial results are reported and reveal the advantages of embedding prescription details in QR code employing a common independent XML scheme.Smart home systems create new opportunities for patient care. In this paper, a role model is created for the different groups of people involved in the care process of an occupant. Based on a systematic literature review seven roles were identified. A second literature review deals with the topic Feedback of Smart Home Systems. Combining both reviews visualization proposals were created and are presented for two of the roles. The role model is adapted to German health system but could be transformed for different countries. To confirm the results an evaluation of role model and visualization proposal should be done in collaboration with possible users of smart homes.Chronic kidney disease (CKD) is a growing Public Health problem.
