Medicare HOS Publications
The Medicare HOS
Partners and other leading health outcomes experts are involved in research
utilizing Medicare HOS
data. These efforts have resulted in the publication of a number of manuals,
peer-reviewed articles, and technical reports. Research based on the HOS data has
been published in academic peer-reviewed journals such as International Journal
of Geriatric Psychiatry, Health Services Research, Health and Quality of Life Outcomes,
International Journal for Quality in Health Care, Health Care Financing Review,
and Cancer. Topics such as depression, smoking, health disparities, and chronic
illness have been investigated utilizing HOS data. For additional information on
Medicare HOS research, please contact the HOS Information and Technical Support Line.
The following list of publications (manuals, peer-reviewed articles, and technical
reports) has been assembled to provide additional information on the Medicare HOS
and to facilitate the utilization of the
HOS data files produced by the Medicare HOS Program. The publications are
organized into the following categories:
(1) Overview, (2) Methodology, (3) Results,
and (4) Applications/Interventions.

Technical Reports
- 2008 HOS-M Sample PACE
Report (PDF, 528 KB) and 2008 HOS-M Sample SNP Report
(PDF, 537 KB)
The Medicare Health Outcomes Survey-Modified (HOS-M) is an abbreviated version of
the Medicare HOS that is administered to Special Needs Plans (SNPs) and Program
of All-Inclusive Care for the Elderly (PACE) Organizations. The HOS-M report presents
physical component summary scores and mental health summary scores, Activity of
Daily Living (ADL) items, and selected health status measures, for the frail, elderly
Medicare beneficiaries for each organization compared to the entire HOS-M sample.
- The Medicare Health
Outcomes Survey Evaluation Final Report (PDF, 2.3 MB)
In 2003 and 2004, CMS funded an independent evaluation of the HOS program. The evaluation
encompassed three components: 1) a review of the context for the HOS program; 2)
an evaluation of the HOS instrument and operational protocol; and 3) an assessment
of policy issues related to turning HOS data into useful information for health
plans, QIOs, CMS and health care researchers. This final report summarizes the findings
of the overall evaluation. A brief overview is provided on the measurement of quality
of care and, in particular, the transition from structural and process measures
of care to outcomes of care. Also discussed is the role of quality of care assessment
and improvement within a broader strategy of health plan performance measurement.
Several national initiatives are noted. Further, factors that contributed to the
development of the HOS program are reviewed, followed by a discussion of the HOS
program administration and data utilization.
- 2008 HOS Sample Baseline Report (PDF, 791
KB)
After the administration of each baseline cohort, a cohort specific baseline report
is produced. The baseline reports present physical component summary and mental
component summary scores. The scores are case mix adjusted using demographics, chronic
medical conditions, and HOS study design variables. The baseline reports also provide
MAO, state, and HOS national information on the Centers for Disease Control and
Prevention (CDC) Healthy Days Measures, the HEDIS Management of Urinary Incontinence
in Older Adults (MUI) Measure, the HEDIS Physical Activity in Older Adults (PAO)
Measure, the HEDIS Fall Risk Management (FRM) Measure, the HEDIS Osteoporosis Testing
in Older Women (OTO) Measure, additional health status indicators, and demographics.
- 2006-2008 HOS Sample Performance Measurement Report (PDF,
909 KB)
After the administration of each follow up cohort, a cohort specific performance
measurement report is produced. A performance measurement report data set is created
by merging a cohort's baseline and follow up data. Additionally, death information
is incorporated into the performance measurement data set for those baseline respondents
who died between baseline and follow up. The HOS performance measurement results
are computed using a rigorous case mix/risk adjustment model. MAOs are rated on
whether they performed Better than Expected, Same as Expected,
or Worse than Expected on Physical and Mental Health. The performance measurement
reports also provide MAO, state, and HOS national information on health status indicators
and demographics.

Implementing the HEDIS® Medicare Health Outcomes Survey: Imputation Analysis
for HOS Income Data (PDF, 141 KB). Data from the Medicare Health Outcomes
Survey (HOS) offer important longitudinal information about insights into the self-assessed
health status of the older population in the United States. CMS has surveyed this
population annually over several years and repeatedly found that income information
is missing in Baseline and Follow-up surveys for about 10-20 percent of respondents.
To address this issue and to generate complete information across HOS data sets,
CMS is collaborating with NCQA to explore and help define a valid income imputation
method using HOS 2000 Cohort 3 Baseline and HOS 2006 Cohort 9 Baseline
data that could be applied to other HOS cohorts.

HOS/CAHPS® Survey Integration Formative Study Design - Final Report (PDF,
728 KB)
This document provides a preliminary assessment to determine the feasibility of
integrating the HOS and the Medicare Advantage (MA) CAHPS® surveys
into one survey instrument. To conduct this assessment, HSAG gathered and reviewed
information from a variety of sources, including 1) key stakeholders; 2) published
and unpublished literature; and 3) analyses of data from the HOS, MA CAHPS®,
and Medicare Fee-For-Service CAHPS® surveys. This report summarizes
the findings. To evaluate the feasibility of integrating the HOS and MA CAHPS®
surveys, seven key aspects of these two surveys were examined: Questionnaire Content;
Survey Administrative Protocols; Analytic Strategies; Sampling Methods; Cost and
Burden; Dissemination of the Results; and Uses of the Results. This report will
help to inform future discussions regarding the advantages and disadvantages of
integration.
- Imputing Physical and Mental Summary Scores (PCS and MCS) for
the Veterans SF-12 Health Survey in the Context of Missing Data (PDF,
387 KB)
This report describes a new method (modified regression estimation) for estimating

the macro.
- Imputing the Physical and Mental Summary Scores (PCS and MCS)
for the MOS SF-36 and the Veterans SF-36 Health Survey in the presence of Missing
Data (PDF, 664 KB)
This report compares five different methods for imputing missing data in responses
to a 36-item health survey. The various methods are compared in terms of both variance
and degree of bias.
- Calculating HOS Performance Measurement Results (PDF,
345 KB)
This document provides a detailed outline of the steps utilized for the calculation
of Cohorts 1-6 HOS Performance Measurement results. The Performance Measurement
results are based on risk adjusted mortality rates, and changes in physical and
mental functioning and well being, among living beneficiaries over a two-year period.
SAS® code utilized for the calculation of the Cohort 3 Performance
Measurement results is also included.
- HOS/VA (Veterans
Administration) Comparison Project Part 1: Measurement Equivalence of Medicare HOS
SF-36 and VA Veterans SF-36 (PDF, 227 KB)
This paper provides evidence that scales from a 36-item health survey can be computed
and compared between the HOS and VA. Although differences exist between the two
instruments, the paper's establishment of partial metric equivalence suggests
that quantitative comparisons between the two samples are appropriate.
- HOS/VA Comparison
Project Part 2: Test of Reliability and Validity at the Scale Level for the Medicare
HOS SF-36 and VA Veterans SF-36 (PDF, 63 KB)
This paper provides evidence that the scales and component summaries from the Veterans
36-Item Health Survey are as reliable and valid as those generated utilizing the
Medicare HOS version. The results strongly suggest that the Veterans 36-Item Health
Survey is suitable for comparisons at the scale level with the Medicare HOS version.

Technical Reports
- Implementing the HEDIS® Medicare Health Outcomes
Survey: The Impact of Health Plan Quality on Medicare Beneficiary Outcomes (PDF,
231 KB). This report assesses the relationship of plan-level performance on HEDIS®
measures of clinical processes and intermediate outcomes with changes over two-years
in the self-reported physical and mental health outcomes from the Medicare HOS among
elderly Medicare plan enrollees with diabetes, hypertension, ischemic heart disease,
and depression. This study represents one of the first attempts to directly link
plan HEDIS® performance to outcome measures of enrollee health.
- Multiple Cohorts Analysis:
Longitudinal Analysis of SF-36® Summary Scores in the Medicare Health
Outcomes Survey - Final Report (PDF, 250 KB) This technical
report examines changes in the PCS and MCS scores for beneficiaries of the Medicare
Advantage Organizations (formerly referred to as Medicare + Choice Organizations)
who completed a Medicare Health Outcomes Survey at yearly intervals from 1998 through
2002. This study incorporates data from those MA beneficiaries that participated
in the HOS on more than one occasion. Trends in physical component summary and mental
component summary scores were examined for beneficiaries who completed the survey
two years, three years, four years, and five years in a row. The examination of
these trends provides information on whether or not declines in health status accelerate
over time or remain constant. This information is valuable in determining the optimal
number of years to wait before conducting the follow up survey.
- Evaluation of Disease Status based on Patient Self-Report in
the Medicare Health Outcomes Survey (PDF, 87 KB)
Using data from patients who are eligible for both Medicare and VA care, this report
compares patient self-reports of chronic conditions to actual chronic conditions
as documented from diagnostic codes obtained from these patients' medical records.
Accuracy of the patient self-reports was quantitatively assessed for a variety of
chronic conditions, by calculating sensitivity (the probability that patients would
report the disease given its indication in the medical records), and specificity
(the probability that patients would not report the disease given its absence in
the medical records).
- Evaluating the Two-Year Follow Up Health Status of Medicare
Fee-For-Service Beneficiaries Using the Health Outcomes Survey (PDF,
2.7 MB)
This report presents an analysis of follow up results for the HOS, which was administered
to a sample of Medicare Fee-for-Service beneficiaries in 1998 and 2000. The primary
goal of this analysis is to assess the feasibility of using longitudinal estimates
of self-reported health status for cohorts of Medicare beneficiaries to evaluate
the care provided to Fee-for-Service beneficiaries by physician group practices
or by Fee-for-Service providers in small geographic areas.
- Comparison of the Health Status of Medicare Fee-For-Service
and Managed Care Enrollees Using the HOS (PDF, 963 KB)
This report compares Medicare Fee-for-Service and Medicare Managed Care enrollees
on a variety of health measures, including physical health status, mental health
status, reports of chronic conditions, and activities of daily living (ADLs). The
report also assesses the extent to which differences in health status are due to
differences in the demographic composition of the two populations.
- MCS Outlier Evaluation Report (PDF, 1.44
MB)
This project was a collaborative effort among CMS, HSAG, and NCQA. The evaluation
involved surveying all 28 outlier plans from the Cohort 1 Performance Measurement
Results, as well as 20 randomly selected "average" plans.
- Report on the Health Status of the Medicare Disabled (PDF,
209 KB)
For Cohort 1 Baseline, 279,135 Medicare beneficiaries were sampled. 167,248
seniors (age 65 or older) responded to the survey. Additionally, 10,513 (out of
a total of 18,864) disabled beneficiaries responded to the survey. This report performs
a comparison between these two groups.
- Report on the Health Status of the Medicare Dual Eligible (PDF,
238 KB)
For Cohort 1 Baseline, 171,510 Medicare beneficiaries responded to the
survey. Additionally, 6,247 beneficiaries enrolled in both Medicare and Medicaid
completed a survey. This report performs a comparison between these two groups.

Technical Reports
- Disparities in Medicare Beneficiary Outcomes: Socio-Demographic
Vulnerability and Prevalent Problems in Older Populations (PDF,
242 KB). This report assesses the extent to which receipt of recommended preventive
services varies by vulnerability status. Studies indicate that vulnerable Medicare
Managed Care subgroups, such as racial/ethnic minorities or low socioeconomic populations,
continue to disproportionately experience quality of care problems. Strategies to
reduce disparities have generally emphasized the importance of improving preventive
services.
- Using Claims Data to Identify Medicare+Choice Enrollees At Risk
for a Decline in Functional Health Status (PDF, 200 KB). This
report presents results from a study sponsored by the Agency for Healthcare Research

health status. Using HOS data and Medicare managed care administrative data, the
analysis characterized utilization of health care and developed risk models for
identifying enrollees appropriate for early medical intervention.
- Report on a Longitudinal
Assessment of Change in Health Status and the Prediction of Health Utilization,

physical and mental health, bodily pain, and impaired Activities of Daily Living
(ADLs) in 2002, and relates these health measures to health care usage and expenditures
in 2003. Additionally, the report examines whether changes in health status from
2000-2002 relate to patient experience with care ratings in 2002. In sum, longitudinal
changes in health status were found to significantly relate to future health care
costs and utilizations.
- The Evaluation of a Mental Component Summary Score Threshold
for Depression Risk in the Medicare Population (PDF, 367 KB)
This report examines different thresholds of mental component summary (MCS) scores
for identifying beneficiaries diagnosed with depression, and those at risk for depression.
The results indicated a low prevalence of depression (7%) based on the diagnoses
recorded on claims data among Medicare FFS beneficiaries. Beneficiaries with depression
diagnoses had lower MCS scores than those without depression diagnoses. The results
indicated that a score of 48 represents reasonable predictive accuracy and would
imply screening for 20% of elderly beneficiaries.
- The Relationship between Health Status,
Utilization, and Expenditures: Comparison between Medicare Managed Care and Fee-For-Service
Beneficiaries (PDF, 554 KB). This report examines possible differences
in the relationship between health status, health expenditures, utilization of services,
and experiences with care between Medicare FFS and managed care (Medicare Advantage
[MA]) beneficiaries. As expected, higher expenditures are associated with lower
PCS and MCS scores, with small but statistically significant differences between
managed care and FFS. Significant differences were found between the self-reported
frequency of FFS and managed care beneficiaries' visits to doctors' offices or clinics
at lower levels of physical and mental health. Finally, managed care beneficiaries
have a significantly higher probability of providing low satisfaction ratings when
compared to FFS beneficiaries.
- National and State Comparisons of Health Status for Medicare
Managed Care and Fee-For-Service Beneficiaries (PDF, 406 KB)
Analysis was conducted to compare the longitudinal change of physical and mental
health status of the 2002-2004 Medicare HOS to a simulated longitudinal change in
the 2002 and 2004 CAHPS Fee-For-Service. At a national level, the results indicated
that there is not a significant difference between Medicare Fee-For-Service and
Managed Care beneficiaries in relation to the amount of physical and mental health
status change for the years examined.

- Medicare HOS National Pilot Project on Depression Final Report (PDF,
438 KB)
From 1999 to 2002, 16 M+COs and six QIOs participated in a pilot project to develop
a strategy for using the HOS results to identify and treat beneficiaries with a
high risk for depression. Claims and HOS data were used to develop a statistical
profile of these high-risk beneficiaries. Each M+CO then provided their primary
care providers with a list of the high-risk beneficiaries in their caseloads, as
well as screening instruments, clinical guidelines, and treatment protocols for
depression management. The participating plans were compared to non-participating
plans to measure the impact on both process measures and HOS scores. A copy of the
Pilot Project User's Guide is available below.
