title: Residential care supply and cognitive and physical problem case mix in nursing homes.
abstract: OBJECTIVE
  A rapid evolution has occurred in state policy and industry practices relative to assisted living and expanded use of residential care facilities for people with physical and cognitive frailty, yet relatively little is known about the interrelationship between this housing supply and nursing-home case mix.
  
  
  METHODS
  The association between residential care supply and the proportion of cognitively and physically impaired nursing facility residents was examined in more than 1,500 facilities in five states.
  
  
  RESULTS
  The proportion of nursing-home cases with only physical and cognitive impairment likely to be affected by emerging long-term care policy appears to be well under 10%. This effect is more persistent among admissions than continuing cases.
  
  
  CONCLUSIONS
  The findings raise caution about the optimistic assumptions of the interplay between residential care/assisted living policy and nursing-home use.
