Background: Improper information transmission can lead to compromised patient safety and quality of life when patients are transferred from one setting to another. Electronic instruments may improve this situation, however, they are rarely used. Objective: The aim of this study therefore was to investigate the technical and organizational feasibility, usability, usefulness and completeness of an electronic instrument that is based on the German HL7 CDA standard for eNursing Summaries. Materials and methods: To this end, a test health telematics infrastructure, which included the German electronic health card, was established and nursing summary application was developed that allowed summary documents to be communicated between a hospital and a nursing home. The users were asked to evaluate the usability of the nursing summary application as well as to compare the usefulness and completeness of electronically and paper transmitted information. Results: This study demonstrated the feasibility of implementing an electronic nursing summary application that was based on the German HL7 CDA standard eNursing Summary and that was integrated in a test health telematics infrastructure. It could also be shown that the users rated this application as usable and that electronically supported patient transfers were superior to paper based ones. The use of the German electronic health card was regarded as a barrier by the users. Discussion: This study emphasizes the feasibility, relevance and barriers of electronically supported transfers of patients with nursing needs. Nurses working in hospitals and long-term care can integrate an application based on the HL7 CDA Standard ePfgebericht into their working processes and get better and more complete information. To ensure continuity of care in a sustainable manner in the future, the German HL7 CDA based eNursing Summary standard should become part of the German telematics infrastructure.
