Implementing the HEDIS® Medicare Health Outcomes Survey: Applying
Missing Data Implementation Methods to HOS Household Income Data (PDF, 359 KB) 2009
The 2009 HOS Cohort 9 Baseline data was used to investigate several missing data
imputation methods for self-reported income, which consistently experiences a high
rate of missing data in the HOS. This report provides a brief summary of selected
statistical methods that use existing information from the HOS data set, applies
them to the data for missing income values, and compares results across the various
methods. This work is an extension of previous NCQA research that used an external
data source for the imputation.
- 1998-2007 Medicare HOS Public Use Files (PUFs) Available in Multiple File
Formats. The PUF data files are available for download from the Inter-University
Consortium for Political and Social Research (ICPSR) website. ICPSR is a unit within
the Institute for Social Research at the University of Michigan and is an international
consortium of academic institutions and research organizations that maintains a
data archive of research files in the social sciences. In addition to the HOS PUFs
available from the Research
Data Files section of this website, users may download PUFs created in SAS,
SPSS, Stata, and tab separated values (TSV) formats from the ICPSR website. The 1998-2007 HOS Cohorts 1-10 Baseline,
the 2000-2004 Cohorts 1-5 Follow Up, and the 1998-2000 Cohort 1 Analytic
through 2005-2007 Cohort 8 Analytic PUFs are available for download at
no cost. A login account and online Terms of Use Agreement are required to download
