title: The effects of a variant of the program for all-inclusive care of the elderly on hospital utilization and outcomes.
abstract: OBJECTIVE
  To compare the effects of the Wisconsin Partnership Program (WPP) on hospital, emergency department (ED), and nursing home utilization with those of traditional care.
  
  
  METHODS
  Quasi-experimental longitudinal cohort design.
  
  
  METHODS
  Selected counties in Wisconsin.
  
  
  METHODS
  WPP elderly enrollees and two matched control groups consisting of frail older people enrolled in fee-for-service insurance plans, Medicare, and Medicaid and receiving home- and community-based waiver services, one from the same geographic area as the WPP and another from a location in the state where the WPP was not offered.
  
  
  METHODS
  Data came from administrative records. Regression and survival analyses were adjusted for case-mix variables.
  
  
  RESULTS
  No significant differences in hospital utilization, ED visits, preventable hospitalizations, risk of entry into nursing homes, or mortality were found. WPP enrollees had more contact with care providers than did controls.
  
  
  CONCLUSIONS
  WPP did not dramatically alter the pattern of care. Part of the weak effect may be attributable to the small numbers of WPP cases per participating physician.
