Dementia Care Research and Psychosocial Factors

Area of Science:

• Gerontology
• Health Informatics
• Public Health

Background:

• Dementia caregiver support interventions need to be scalable and accessible.
• CommunityRx-Dementia (CRxD) is an IT-based intervention designed to connect caregivers with community resources.
• Caregiver outcomes, including unmet needs and resource knowledge, are critical areas for intervention.

Purpose of the Study:

• To evaluate the effectiveness of the CommunityRx-Dementia (CRxD) intervention compared to usual care (UC).
• To assess the impact of CRxD on dementia caregivers' unmet needs and knowledge of community resources.
• To determine the effect of CRxD on acute care utilization among dementia caregivers.

Main Methods:

• A randomized trial involving 343 dementia caregivers comparing CRxD to usual care (UC).
• Outcomes measured included self-reported unmet needs, resource knowledge (at baseline, 1, and 3 months), and acute care utilization (at 12 months).
• Statistical analyses used mixed-effects regression models for knowledge/needs and negative binomial regression for acute care utilization.

Main Results:

• At 3 months, the CRxD group showed significantly greater resource knowledge (6.5 vs 5.2 resources) and fewer unmet needs (2.8 vs 3.6) compared to the UC group.
• Over 12 months, caregivers in the CRxD group had lower emergency department visit rates (IRR: 0.6) than UC participants.
• Hospitalization rates were similar between the CRxD and UC groups (IRR: 0.7).

Conclusions:

• The low-intensity CommunityRx-Dementia (CRxD) intervention effectively enhances dementia caregiver knowledge of resources.
• CRxD demonstrates a significant reduction in unmet needs among dementia caregivers.
• This IT-based social care intervention may reduce emergency care utilization for dementia caregivers.
