SEER-Medicare Health Outcomes Survey (MHOS) Linkage Project:
What are the two components of SEER-MHOS?
NCI's SEER program collects information about cancer site, stage, and histology for
persons newly diagnosed with cancer who reside in one of the SEER geographic areas.
The MHOS was developed by the National Committee for Quality Assurance (NCQA) under
contract to CMS. It measures the outcomes of care provided by Medicare Advantage managed care plans to their members.
The MHOS includes a 95-item core questionnaire administered to 1,000 randomly selected
members of each managed care organization that participates in the program. In plans with
fewer than 1,000 enrollees, all eligible members are surveyed. The survey was administered
in May 1998 and again to the same group in the spring of 2000. A new cohort is selected
each year for baseline measurement and a 2-year follow-up assessment.
