CommunityRx-Dementia + Peer Navigation (CRxDpeer)

In 2022, more than 11 million Americans, half of whom were 50 or older, provided more than 18 billion hours of unpaid care for people with dementia. Many caregivers have no formal training and limited support. The White House, along with the Alzheimer's Association, the National Institute on Aging and others, is calling for urgent attention to the health and well-being of the fast-growing population of dementia caregivers, with heightened concern for caregivers living in historically marginalized communities. Scalable, evidence-based, solutions leveraging existing assets are urgently needed to meaningfully reach all caregivers. Our approach to addressing these unmet needs, CommunityRxDpeer, is an information technology-based, low-intensity, health system-initiated community resource navigation intervention delivered to caregivers by peer caregiver navigators remotely over time. Essential components include education about common social, including caregiving needs, activation of personalized community resource information and ongoing navigation-focused support. The CRxDpeer intervention components are informed by evidence-based "processes" identified in the Grey et al. Self- and Family Management Framework that are known to promote desirable health outcomes among people living or caring for others with chronic health conditions, including dementia. Prior CommunityRx trials have successfully deployed community members, clinicians and researchers to deliver the intervention in real-world and research settings with positive outcomes in a wide-range of populations. In this pragmatic trial, experienced and willing dementia caregivers from the CRxDementia cohort (2020-24) will be recruited and trained as peer navigators to deliver CRxDpeer. Using a hybrid effectiveness implementation design with a double-blind RCT, we will evaluate the effectiveness of CRxDpeer versus usual care on caregiver health and well-being, healthcare utilization and social care outcomes. In parallel, we will evaluate the adoption, fidelity and cost of CRxDpeer and, using mixed methods, characterize perceived mechanisms of impact on caregivers delivering and receiving CRxDpeer. The specific objectives are to demonstrate that CRxDpeer can be delivered in the real world with fidelity and to assess the effectiveness of this approach on important outcomes. Resource referral and peer support IT platforms deployed for intervention delivery are already in commercial use, paving a viable path to replication and scale as a stand-alone or adjunct to other caregiver interventions, like the Center for Medicare \& Medicaid Guiding an Improved Dementia Experience (GUIDE) Model test, which aims to enable people with dementia to age at home by supporting family caregivers with education and resources. CRxDpeer has the potential to improve the health and well-being of millions of dementia caregivers and their care recipients by meaningfully connecting them to vital social and caregiving resources and creating opportunity for willing and experienced caregivers to support with others.
