Case management is a complex intervention aimed at addressing a variety of health needs of people in their social environment. Case management for people with dementia is often poorly defined and insufficiently described. The crucial process steps are often not well understood. We aim to map and compare the key components, processes and contextual factors of case management programmes for dementia and to explore aspects of the interventions' generalisability. Our search covered the databases PubMed, CINAHL, Cochrane and GeroLit, as well as policy papers from international organisations. We included qualitative, quantitative and mixed-methods studies in the English or German language that was published between 1999 and 2020. The programmes were analysed according to programme characteristics, case management intervention and the structural and processing conditions. We identified 67 studies dealing with 25 programmes. Approximately half of the programmes were investigated in randomised controlled trials, two programmes used a mixed-methods design and the remaining were the subject of pre-post cohort studies. Participants in the studies were predominantly dyads of people with dementia and their informal caregivers. About half of the programmes reported a theoretical framework. All the programmes were derived from case management approaches or referred to such approaches. Despite huge differences in implementation, all the programmes covered the case management steps. In 14 out of 25 programmes, case management was carried out without additional intervention, the other programmes provided mainly education and training for informal caregivers. Costs of the case management interventions were stated in more than half of the programmes.The effectiveness and generalisability of dementia-specific case management interventions could be enhanced if the framework introduced in the review was used in the future by policy, practice and research.
