A Scoping Review of Dementia Interventions in Home-Based Primary Care

Home-based primary care (HBPC) provides interdisciplinary, longitudinal, comprehensive care at home to homebound older adults. The prevalence of dementia among HBPC recipients is approximately 50%. To date, little research has been performed to determine whether dementia-specific interventions have been conducted in HBPC or their efficacy. We performed a scoping review to assess the landscape of dementia interventions in HBPC.

Systematic scoping review.

Care delivery programs for patients or caregivers of patients with dementia for the purpose of improving the management of dementia in the setting of HBPC.

The PRISMA-ScR protocol was followed. Literature searches were performed using PubMed, Embase, and Scopus for articles on dementia-focused interventions implemented in HBPC. Articles were excluded if they consisted of abstracts only, were not in English, or were not dementia interventions in HBPC.

A total of 1657 unique titles and abstracts were screened. Overall, 1584 titles and abstracts were excluded, resulting in 73 full-text studies to assess for eligibility. Of these 73 full-text studies, 1 study met criteria for inclusion, an observational study assessing the implementation of the Resources for Enhancing Alzheimer's Caregiver Health (REACH) intervention in Veterans Affairs HBPC. That study found the intervention to be effective in reducing caregiver burden, with a decrease of 2 hours on duty per day, trending toward significance. Among the excluded 72 full-text studies, some studies included potentially relevant interventions that could be translated into HBPC care, including dementia interventions that targeted long-term services and supports, office-based primary care and other nonhome settings such as nursing homes, and home-based palliative care.

Despite high prevalence of dementia among homebound older adults receiving HBPC, there are a dearth of studies on HBPC-specific dementia interventions. Future studies should consider adapting and testing interventions found to be effective in other settings to HBPC.
