Objectives: To identify available literature on the impact of built environments on health, behavior, and quality of life of individuals with intellectual disabilities in long-term care. Additionally, we aimed to map the available literature, (re)frame the overall research situation in this area, and formulate recommendations.
Background: Long-term care facilities in the Netherlands are planned without using knowledge from research regarding evidence-based design because it is unclear what evidence is available about the impact of long-term care built environments on individuals with intellectual disabilities receiving 24/7 care.
Methods: Twelve scientific databases were searched for keyword combinations. After systematically screening 3,095 documents, 276 were included in the analysis.
Results: There is an underrepresentation of research and publications in intellectual disabilities, compared to other user groups living in long-term care facilities. A total of 26 design components were found in all groups; as for intellectual disabilities, research was available on only seven of them. Community care, home-likeness, and variety seem to have a positive effect on health, behavior, and quality of life. There are conflicting results regarding the effects of house size.
Conclusions: Although individuals with intellectual disabilities live in long-term care facilities, sometimes for life, little research has been conducted on the impact of the built environment on them. In the future, more empirical research should be conducted, addressing all aspects of quality of life and specific design components, with hypotheses based on needs assessments and the use of good research designs. This requires an investment of time and funding.
