[Sectoral interface-an opportunity for health services research?]

The request for increased outpatient care is currently widely discussed in healthcare debates. With that, the sectoral interface (outpatient/hospital) is receiving greater attention, which provides an incentive for better cooperation and coordination of all healthcare providers. This also marks an opportunity to establish new cross-sectoral structures-also for research. The definitions of cross-sectoral care and the research content need to be in a standardized and consolidated manner. The provision of treatment data along the entire patent's path remains essential for health services research. In this context, the cross-sectoral interface could be regarded as fragile in that it is particularly sensitive to disruptions. The current increasing digitalization can also be seen as an opportunity to minimize the loss of information through the further development of cross-sectoral structures and to improve patient care, while simultaneously making a contribution to research across sectoral borders.
