Caregiver preferences and willingness-to-pay for home care services for older people with dementia: A discrete choice experiment in the Milan metropolitan area.

Objectives: Dementia is a major health and social care challenge in high-income countries where most people are cared for in their own homes. This study aimed to elicit caregiver preferences for alternative bundles of home care services in the Milan metropolitan area.

Methods: A binary discrete choice experiment was administered to a sample of informal caregivers of people with dementia recruited through a network of non-profit organizations. The experiment included four attributes: 1) number of home care hours per month; 2) type of care; 3) caregiver peer support group organization; 4) monthly family's cost (in euros), each articulated into three levels. A mixed logit model was applied to analyze the responses using Stata.

Results: A total of 93 self-administered questionnaires were collected in January-April 2023. Two-thirds of both caregivers (67.7 %) and care recipients (65.6 %) were female, with a mean age of 59.0 (±12.1) years and 82.2 (±6.5) years, respectively. The experiment showed that increased home care hours, mixed health and social home care, caregiver meetings with professional support and lower monthly costs were mostly valued by caregivers. Some preference heterogeneity was detected in relation to care recipient's characteristics (e.g., age).

Conclusions: These results are expected to inform policymakers about caregiver priorities in the field of dementia based on the values placed on hypothetical public home care services.
