title: Measuring patient-level clinical outcomes of home health care.
abstract: OBJECTIVE
  To examine the use of the Outcomes Assessment and Information Set (OASIS) data to analyze patient-level outcomes of home health care.
  
  
  METHODS
  OASIS data were obtained on 1,015 patients who received home health care services for 60 days or fewer from a large, independent home health agency between August 1998 and December 1999.
  
  
  METHODS
  An index was constructed consisting of 16 OASIS measures, primarily activities of daily living (ADL) and instrumental activities of daily living (IADL). Scores were computed for functional status on admission and at discharge. Predictors of functional status at discharge were identified by regression analysis.
  
  
  RESULTS
  78.1% of patients improved, 18.5% declined, and 2.8% showed no change. The model explained 57.2% of variance in functional status at discharge. Age, visual impairment, having Medicaid as a payer, urinary incontinence, cognitive impairment, and use of unplanned or emergency care were negatively associated with functional outcomes of care. Being treated for open wounds or lesions, cardiovascular and orthopedic conditions were positively associated with functional outcomes.
  
  
  CONCLUSIONS
  OASIS data can be used to analyze patient-level functional outcomes of short-term home health services. Further research is needed to continue refining methods of analyzing patient outcomes and their predictors.
