Interventions to Prevent or Delay Long-Term Nursing Home Placement for Adults with Impairments—a Systematic Review of Reviews

Abstract

Background: With continued growth in the older adult population, US federal and state costs for long-term care services are projected to increase. Recent policy changes have shifted funding to home and community-based services (HCBS), but it remains unclear whether HCBS can prevent or delay long-term nursing home placement (NHP). Methods: We searched MEDLINE (OVID), Sociological Abstracts, PsycINFO, CINAHL, and Embase (from inception through September 2018); and Cochrane Database of Systematic Reviews, Joanna Briggs Institute Database, AHRQ Evidence-based Practice Center, and VA Evidence Synthesis Program reports (from inception through November 2018) for English-language systematic reviews. We also sought expert referrals. Eligible reviews addressed HCBS for community-dwelling adults with, or at risk of developing, physical and/or cognitive impairments. Two individuals rated quality (using modified AMSTAR 2) and abstracted review characteristics, including definition of NHP and interventions. From a prioritized subset of the highest-quality and most recent reviews, we abstracted intervention effects and strength of evidence (as reported by review authors). Results: Of 47 eligible reviews, most focused on caregiver support (n = 10), respite care and adult day programs (n = 9), case management (n = 8), and preventive home visits (n = 6). Among 20 prioritized reviews, 12 exclusively included randomized controlled trials, while the rest also included observational studies. Prioritized reviews found no overall benefit or inconsistent effects for caregiver support (n = 2), respite care and adult day programs (n = 3), case management (n = 4), and preventive home visits (n = 2). For caregiver support, case management, and preventive home visits, some reviews highlighted that a few studies of higher-intensity models reduced NHP. Reviews on other interventions (n = 9) generally found a lack of evidence examining NHP. Discussion: Evidence indicated no benefit or inconsistent effects of HCBS in preventing or delaying NHP. Demonstration of substantial impacts on NHP may require longer-term studies of higher-intensity interventions that can be adapted for a variety of settings. Registration PROSPERO # CRD42018116198.
