IWISH Impact Study Research Design & Analysis Plan

Abt Global


February 5, 2021

This impact study compares outcomes for residents living in 40 properties that implement the HUD’s Supportive Services Demonstration’s Integrated Wellness in Supportive Housing (IWISH) program with outcomes for residents living in 84 similar properties that do not implement IWISH. The study will assess whether IWISH:

  • Reduces unplanned hospitalizations and the use of other types of acute care,
  • Increases the use of primary and nonacute care, and
  • Increases the length of stay in housing by reducing transitions to long-term care facilities.
