Abstract

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 (χ2, 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. Copyright © 2009 John Wiley & Sons, Ltd.
