Hospital Improvement Innovation Network

OHA is one of 16 organizations nationwide selected to direct hospital efforts to reduce preventable health care-acquired conditions and hospital readmissions.

Known as the Hospital Innovation Improvement Network, or HIIN, this program aims to transform health care delivery systems across the country. The OHA HIIN, which builds on the Centers for Medicare & Medicaid Services Partnership for Patients initiative, began in 2016 and operated through 2020.


By collaborating with multiple partners and other state hospital associations to ensure sharing of best practices and education, OHA provides participating hospitals a robust experience for improving care.

Member hospitals participating in the OHA HIIN work to achieve:

  • A 20% decrease in overall hospital-acquired conditions
  • A 12% reduction in 30-day hospital readmissions as a population-based measure (readmissions per 1,000 people) from the 2014 baseline
  • Health equity for Medicare beneficiaries

The Centers for Medicare & Medicaid Services monitor and evaluate the activities of the Hospital Improvement Innovation Networks to ensure programs are generating results and improving patient safety.


OHA has partnered with Battelle, a global research and development organization, to implement the use of predictive analytics tool WayFinder™ in the HIIN contract. This allows participating hospitals to leverage the software at minimal or no cost, as well as use additional analytic opportunities that are being designed specifically for the Partnership for Patients initiative.
