Residential characteristics, social factors, and mortality among adults with intellectual disabilities: transitions out of nursing homes.

Kelly and colleagues tracked 330 adults with intellectual disability who lived in nursing homes. They measured the size of each home, how nice the building was, and how much the residents joined community life. Ten years later they looked at who was still alive.

They used medical records and on-site checklists. Age, health status, and daily-living skills were already known, so the team could separate those factors from the home itself.

People in smaller homes died less often. Good lighting, clean halls, and private rooms also helped. The biggest protector was joining clubs, visiting family, or working outside the building.

Even after counting age and illness, residents in the most integrated, smallest places had a clear survival edge over ten years.

Kozma et al. (2009) pooled 68 studies and found the same pattern: community houses beat large facilities in most life areas. Kelly’s nursing-home data now show the benefit holds inside institutional walls too, not just after leaving them.

Cameranesi et al. (2022) moved adults with profound ID from big institutions to small community homes and saw quality-of-life jump within six months. Their move study extends Kelly’s finding: shrinking the setting and boosting social ties improves both daily happiness and long-term survival.

Matson et al. (2009) warned that adults with ID still have tiny social networks. Kelly’s result turns that problem into action: grow those networks and you may literally add years to life.

You can’t change a nursing-home license overnight, but you can change what happens inside. Push for house-size units, schedule regular community walks, and invite families to dinner. These low-cost steps may lengthen the lives of the adults you serve.
