Home and Community-Based Services: A Systematic Review and Evidence Map

Many adults aged 60 years or older have functional limitations and require home and community-based services (HCBS) to support their independence and delay the transition to an institutionalized setting. This systematic review provides an evidence map of the existing literature on HCBS identifying evidence gaps for policy and research.

A comprehensive literature search of multiple databases including Medline, Embase, and Scopus was conducted through December 7, 2023. Interviews with various stakeholders were conducted to solicit additional perspectives. Narrative and thematic synthesis was conducted to evaluate HCBS in terms of populations, interventions, outcomes, person-centeredness, and relevant quality measures.

We identified 27 primary studies and 29 quality measures. Populations of HCBS studies can be categorized as those with functional disability, cognitive impairment, high-risk/frail conditions, and disease-specific conditions (Parkinson's disease, Alzheimer's disease, and post-stroke). HCBS interventions targeted optimization of person-centered planning, nonpharmacological approaches for dementia care, physical rehabilitation, self-directed home care, geriatric resources for practical support at home, and interdisciplinary care coordination for high-risk conditions. Person-centered planning and self-direction of HCBS services were not explicitly described in many studies and very few studies focused on addressing health-related social needs, whereas the majority reported primary clinical outcomes. Numerous quality measures exist for HCBS, some of which were validated, addressed multiple person-centered domains, and may apply across various conditions and populations. Key challenges in the literature on HCBS include limited number of randomized trials, inadequate descriptions of interventions to determine person-centeredness, limited information on facilitators and barriers, and limited information on workforce challenges in recruiting, retaining, and training personnel delivering HCBS.

This evidence map describes the current state of HCBS and identifies evidence gaps for future research and policy decisions.
