Background and Objectives
In the absence of effective pharmacotherapy, there is an urgent need to test evidence-based dementia care interventions using pragmatic trial approaches. We present results from a study in which an evidence-based, non-pharmacologic intervention for persons living with Alzheimerâs disease and related dementia (ADRD) and their informal caregivers, Care of Persons with Dementia in their Environments (COPE), was tested in a Medicaid and state revenue-funded home and community-based service (HCBS) program.
Research Design and Methods
Using pragmatic trial design strategies, persons living with ADRD and their caregivers were randomly assigned as dyads to receive COPE plus usual HCBS (COPE; N=145 dyads) or usual HCBS only (Usual Care, or UC; N=146 dyads). Outcomes were measured pre-randomization, and 4 and 12 months post-randomization. Outcomes for persons living with ADRD included functional independence, activity engagement, self-reported quality of life, and behavioral and psychological symptoms. Caregiver outcomes included perceived well-being, confidence using dementia-management strategies, and degree of distress caused by behavioral and psychological symptoms.
Results
After 4 months, caregivers receiving COPE reported greater perceived well-being (least squares mean=3.2; 95% CI: 3.1-3.3) than caregivers receiving UC (3.0; 2.9-3.0; p<0.001), and persons living with ADRD receiving COPE, compared to those receiving UC, showed a strong trend toward experiencing less frequent and less severe behavioral and psychological symptoms (9.7; 5.2-14.2 vs. 12.7; 8.3-17.1; p=0.07). After 12 months, persons living with ADRD receiving COPE were more engaged in meaningful activities (2.1; 2.0-2.1 vs. 1.9; 1.9-2.0; p=0.02) than those receiving UC.
Discussion and Implications
Embedding COPE in a publicly-funded HCBS program yielded positive immediate effects on caregiversâ well-being, marginal positive immediate effects on behavioral and psychological symptoms, and long-term effects on meaningful activity engagement among persons living with ADRD. Findings suggest that COPE can be effectively integrated into this service system, an important step towards widespread adoption.
