The project focuses on Dementia Care Management (DeCM) as a measure variable of the National Dementia Strategy. Based on the already positively evaluated DelpHi standard for the outpatient care of people with dementia, the development and implementation of a regional and cross-sector DeCM model for the Siegen-Wittgenstein region (SW) is being investigated. Following a participatory research approach, practitioners from various care sectors as well as people with dementia and their relatives from SW are involved as co-researchers in all phases of the study.
