  • Implementing the HEDIS® Medicare Health Outcomes Survey: Final Protocol Analysis Cohorts 5-9 (2002-2006) (PDF, 141 KB) This Protocol Analysis report is based on data analysis from the 2002-2006 (Cohorts 5-9) Medicare Health Outcomes Survey (HOS) administrations. The purpose of this report is to describe changes in the composition of the cohorts over the years and to examine the quality and completeness of the survey data. The 2006 administration of the HOS marked its ninth year of baseline administration and seventh year of follow-up administration in Medicare Advantage (MA) plans. It is also the first year that the revised HOS questionnaire, referred to as HOS 2.0, replaced the previous questionnaire version. NCQA performed a series of analyses of the available HOS data to uncover trends in HOS administration in recent years.
