Residential Environments for Older Persons: A Comprehensive Literature Review (2005–2022)

Abstract

Background: Independent noninstitutional and institutional residential long-term care environments for older persons have been the subject of significant empirical and qualitative research in the 2005–2022 period. A comprehensive review of this literature is reported, summarizing recent advancements in this rapidly expanding body of knowledge. Purpose and Aim: This comprehensive review conceptually structures the recent literature on environment and aging to provide conceptual clarity and identify current and future trends. Method and Result: Each source reviewed was classified as one of the five types—opinion piece/essay, cross-sectional empirical investigation, nonrandomized comparative investigation, randomized study, and policy review essay—within eight content categories: community-based aging in place; residentialism; nature, landscape, and biophilia; dementia special care units; voluntary/involuntary relocation; infection control/COVID-19, safety/environmental stress; ecological and cost-effective best practices; and recent design trends and prognostications. Conclusions: Among the findings embodied in the 204 literature sources reviewed, all-private room long-term care residential units are generally safer and provide greater privacy and personal autonomy to residents, the deleterious impacts of involuntary relocation continue, family engagement in policy making and daily routines has increased, multigenerational independent living alternatives are increasing, the therapeutic role of nature and landscape is increasingly well-documented, ecological sustainability has increased in priority, and infection control measures are of high priority in the wake of the coronavirus pandemic. Discussion of the results of this comprehensive review sets the stage for further research and design advancements on this subject in light of the rapid aging of societies around the globe.
