title: Functional gains and therapy intensity during subacute rehabilitation: a study of 20 facilities.
abstract: OBJECTIVE
  To document patient, program characteristics, and therapy service provision in subacute rehabilitation across 3 types of facilities that provide subacute rehabilitation, to examine the determinants of therapy intensity, and to evaluate the contribution of rehabilitation services to functional gains.
  
  
  METHODS
  A retrospective study linking administrative billing data and patients' functional assessment records.
  
  
  METHODS
  Twenty facilities part of the Uniform Data System for Medical Rehabilitation (UDSMR) subacute database
  
  
  METHODS
  A total of 1976 billing records of patients with stroke, orthopedic, and debility impairments, discharged in 1996 and 1997, were retrieved and linked with the FIM trade mark instrument ratings from UDSMR subacute database.
  
  
  METHODS
  Not applicable.
  
  
  METHODS
  Total therapy intensity and Rasch-transformed FIM domain gains (ie, gains in self-care, mobility, cognition).
  
  
  RESULTS
  Therapy intensity was mostly determined by impairment and facility type, although variances explained by the predictors were small. Patients in all 3 impairment groups made functional gains; gains were related weakly, although significantly, to therapy intensity and rehabilitation duration after controlling for other variables.
  
  
  CONCLUSIONS
  The provision of rehabilitation therapies varied across facilities. Skilled nursing facilities with subacute rehabilitation units tended to provide more therapies than subacute units in acute or rehabilitation hospitals.
