Due to demographic trends, the demand for long-term care continues to rise, posing challenges to the healthcare system, particularly in terms of nursing care. In this context, it is important to focus not only on improving care structures but also on finding ways to reduce the demand of care services. The aim of the WEGE study is therefore to compare healthcare trajectories of AOK-insured individuals (retrospective 5-year period) in order to identify care pathways that are effective in avoiding or delaying the onset of long-term care needs. The results will contribute to expanding our understanding of the factors contributing to long-term care dependency and deriving therapeutic, preventive, and rehabilitative potentials for the care of older insured individuals.
