Caregiving burden and healthcare utilization in family caregivers of people with dementia: Long term impact of the public family caregiver intervention

Despite community-based interventions to decrease the caregiving burden on family caregivers of people with dementia (PwD), long-term assessment of community-based public programs is lacking. Therefore, the study aims to identify the long-term effects of community-based dementia caregiver intervention on the caregiving burden and healthcare utilization among family caregivers for PwD. Additionally, we investigated the predictors of caregiving burden and healthcare utilization. Of the participants, 32 (76%) intervention and 15 (38%) control groups responded to the one-year follow-up. We assessed caregiver burden using the short-form Zarit Burden Interview (sZBI) and collected healthcare utilization data using questionnaire at baseline and 12 months. Compared with the control group, the intervention group did not experience a reduction in caregiving burden and healthcare utilization. Predictors of caregivers' perceived burden were spouses as the primary caregiver and having multiple comorbidities. The predictors identified in this study should be considered when implementing public family support programs.
