Update on the Medicare Health Outcomes Survey (HOS)

• Developed and implemented in 1998 as a Medicare HEDIS® Effectiveness of Care Measure.

• In addition to health outcome and functional status measures, the HOS is used to collect Urinary Incontinence in Older Adults, Physical Activity in Older Adults, Osteoporosis Testing in Older Women, and Fall Risk Management HEDIS® measures.

• CMS uses HOS data to meet the MMA 2003 Section 722(a)(3)(A)(i) mandate requiring the collection, analysis, and reporting of data that permits the measurement of health outcomes and other indices of quality.

The goal of the HOS program: To gather valid, reliable, and clinically meaningful data that are used by:

• MCOs, providers, and quality improvement organizations to monitor and improve health care quality.

• CMS to assess the performance of MCOs and reward high performers.

• Medicare beneficiaries, their families, and advocates when making health care purchasing decisions.

• Health researchers to advance the state-of-the-science in functional health outcomes measurement, and quality improvement interventions and strategies.
