Welcome to the Medicare Health Outcomes Survey (HOS) Website

The Medicare HOS was the first patient-reported outcomes measure used in Medicare managed care. The goal of the Medicare HOS program is to gather valid and reliable clinically meaningful data that have many uses, such as targeting quality improvement activities and resources; monitoring health plan performance and rewarding top-performing health plans; helping people with Medicare make informed health care choices; and advancing the science of functional health outcomes measurement. Managed care plans with Medicare Advantage (MA) contracts must participate.

Each year a random sample of people with Medicare is drawn and surveyed from each participating Medicare Advantage Organization (MAO) that has a minimum of 500 enrollees (i.e., a survey is administered to a different baseline cohort, or group, each year). Two years later, the baseline respondents are surveyed again (i.e., follow up measurement). Cohort 1 was surveyed in 1998 and was resurveyed in 2000. During the most recent HOS administration (2023 Round 26), Cohort 26 was surveyed and Cohort 24 was resurveyed using HOS 3.0. For data collection years 1998-2006, the standard MAO baseline sample size was one thousand. In 2007, the standard sample size was increased to twelve hundred. Since 2019, MAOs can request oversampling if the contract's enrollment permits a sample size larger than the standard sample of 1,200.
