Dementia Care Research and Psychosocial Factors

Area of Science:

• Gerontology
• Neuroscience
• Health Services Research

Background:

• Understanding patient and caregiver priorities is crucial for developing effective dementia treatments.
• Divergent preferences between persons living with dementia (PWD) and their family care partners can influence treatment acceptance and adherence.

Purpose of the Study:

• To determine the relative importance of various outcome domains when selecting hypothetical dementia treatments.
• To compare the priorities of PWD and family care partners regarding dementia treatment outcomes.

Main Methods:

• A discrete choice experiment (DCE) was conducted with 201 participants (154 care partners, 47 PWD).
• Participants evaluated hypothetical dementia treatments based on attributes like brain function, symptoms, physical function, home time, caregiver stress, and socialization.
• Data were analyzed using mixed-effects logistic regression, with qualitative analysis of field notes.

Main Results:

• Relief of distressing symptoms and increasing home time were the highest priority outcomes for all participants.
• PWD placed higher value on increasing home time, improving physical function, reducing caregiver stress, and enhancing socialization compared to care partners.
• Qualitative analysis identified themes related to participant decision-making and DCE experience.

Conclusions:

• Increasing home time is a key outcome for both PWD and care partners.
• Treatment outcome priorities differ significantly between PWD and their care partners.
• DCEs can serve as valuable tools for communication and values elicitation in dementia care discussions.
