Objective: To evaluate a case management (CM) model for people with mild dementia, whereby resources within the family and in the community were mobilized and optimally used.; Method: Community dwelling psychiatric and geriatrics outpatients with mild dementia were randomized to receive CM by a trained occupational therapist for 4 months (CM group, N = 59) or usual care only (control group, N = 43). Primary outcome indicators included the Zarit Burden Scale (ZBI), General Health Questionnaire (GHQ), and Personal Well-Being Index for Adult (PWI-A) of the family caregivers. Secondary outcome indicators included the Mini-Mental State Examination (MMSE), Neuropsychiatric Inventory (NPI), Cornell Scale for Depression in Dementia (CSDD), and Personal Well-Being Index for Intellectually Disabled (PWI-ID) of the demented subjects as measured at fourth and twelfth months.; Result: CSDDis reduced in the CM group at fourth month, but not at twelfth month. The changes in outcome variables of persons with dementia did not differ between the groups (Mann-Whitney U-test, p > 0.05). At follow-up, CM group used more day care and domestic helpers than control group (chi (2), p > 0.05).; Conclusion: Case management for Chinese persons with mild dementia outpatients did not show significant effects in reducing caregiver burden, but encouraged family caregivers to seek external support.;
