HOS

What is the Health Outcomes Survey (HOS)?

HOS is an annual survey administered in August to a random sample of Medicare Advantage patients. The same patients are surveyed again two years later to assess change in physical and mental health status.

The survey is a measurement of patients' perception of their physical and mental health and overall quality of life. 

There are five HOS measures — two functional health measures and three HEDIS® Effectiveness of Care measures in the annual Medicare Part C Star Ratings:

• Improving or Maintaining Physical Health — Functional health measure                
• Improving or Maintaining Physical Health — Functional health measure               
• Monitoring Physical Activity — HEDIS® Effectiveness of Care measure               
• Improving Bladder Control — HEDIS® Effectiveness of Care measure                
• Reducing the Risk of Falling — HEDIS® Effectiveness of Care measure

The survey results impact CMS star ratings.
