The document discusses a decision support system called CEPHOS-LINK DSS that was designed to aid policy makers and stakeholders in understanding factors that may impact psychiatric rehospitalization. The system generates scenarios using data from 6 European countries to model how resources could be allocated and services planned. It is intended as a proof of concept that could potentially be expanded to include additional countries and data sources. The overall goal is to facilitate discussion between sectors and provide an accessible way to explore rehospitalization issues in different contexts.
