To obtain insight into facilitating factors for case management in dementia care, we conducted a qualitative study with 13 online focus groups (OFGs). Participants were professionals involved in dementia case management (N=99). We used mind-maps and the method of constant comparison for analysis. Participants perceived OFGs as a useful tool to explore their perspectives. The perceived advantage of OFGs was the flexibility and convenience of logging in at any time or place preferred. Five facilitating factors for case management were identified in the OFGs: 1. Good cooperation between partners; 2. Organisational embedding with an independent position of case managers; 3. Structural funding; 4. Competent case managers; 5. Familiarity with case management in the region. Good cooperation was essential for successful dementia case management and should thus be a primary concern for care providers.
