Empowering Formerly Homeless Older Adults to Engage in Advance Care Planning in Permanent Supportive Housing (ACP-PSH): An RCT

Advance care planning (ACP) aims to elicit patients' medical preferences; yet older adults experiencing chronic homeless have low rates of ACP. Significant policy attention has focused on rehousing chronically homeless people into Permanent Supportive Housing (PSH), subsidized permanent housing with voluntary supportive services. Our team will use PREPARE for Your Care (PREPARE) - an easy-to-use, evidence-based, online ACP program with video stories. This program includes easy-to-read advance directives, an ACP group visit guide, and an ACP one-on-one facilitation guide. Our team developed a Community Advisory Board (CAB) and together identified preliminary adaptations to the PREPARE materials for the PSH setting.

The objective of this proposal is to co-develop PREPARE-PSH and compare the effectiveness of facilitated group versus one-on-one visits among formerly chronically homeless older adults in PSH. In Aim 1 the investigators will engage in a rigorous co-development process through in-depth interviews and focus groups with 20 PSH residents and the CAB. The investigators will use a theory-informed framework and qualitative content analysis to co-create a PREPARE-PSH program. For Aim 2, the investigators will conduct a Hybrid (NIH Stage III efficacy/effectiveness), Type 1 cluster randomized trial to compare the delivery of PREPARE-PSH through facilitated groups vs. one-on-one visits using mixed effects models. Randomization will be at the site level, balanced by site size. In Aim 3, the investigators will purposively sample Aim 2 participants for in-depth interviews (n=30-40), conduct focus groups with PSH staff (n=30-40), and obtain input from CAB members (total n=10-15). The investigators will explore implementation-relevant factors associated with: (a) high and low ACP engagement and sustainability of PREPARE-PSH using the Behavior Change Wheel (BCW and the Consolidated Framework for Implementation Research (CFIR) model. Relevance to NIH and public health: PREPARE-PSH may reduce health disparities in ACP among formerly chronically homeless older adults.
