Introduction

The Agency for Healthcare Research and Quality (AHRQ) is pleased to release the 2006 National Healthcare Disparities Report (NHDR) on behalf of the U.S. Department of Health and Human Services (HHS) and in collaboration with an HHS-wide Interagency Work Group. Like previous reports, the 2006 NHDR also received significant guidance from AHRQ leadership and AHRQ's National Advisory Committee. This fourth annual report to Congress provides a comprehensive national overview of disparities in health care among racial, ethnic, and socioeconomici groups in the general U.S. population and within priority populations and tracks the progress of activities to reduce disparities.

The NHDR tracks disparities related to quality of health care and access to health care. Measures of health care quality address the extent to which providers and hospitals deliver evidence-based care for specific services as well as the outcomes of the care provided. They are organized around four dimensions of quality—effectiveness, patient safety, timeliness, and patient centeredness—and cover four stages of care—staying healthy, getting better, living with illness or disability, and coping with the end of life. Measures of health care access include assessments of how easily patients are able to get needed health care and their actual use of services. They are organized around two dimensions of access—facilitatorsii and barriers to care and health care utilization.

The NHDR is complemented by its companion report, the National Healthcare Quality Report (NHQR), which uses the same quality measures as the NHDR to provide a comprehensive overview of the quality of health care in America. Both reports measure health care quality and track changes over time but with different orientations. The NHQR addresses the current state of health care quality and the opportunities for improvement for all Americans as a whole. This perspective is useful for identifying where we are doing well as a Nation and where more work is needed. The NHDR addresses the distribution of improvements in health care quality and access across the different populations that make up America. This perspective is useful for ensuring that all Americans benefit from improvements in care. Perspectives from both reports are needed for a complete understanding of quality of health care, and both reports support HHS Secretary Mike Leavitt's 500-Day Plan to fulfill the President's vision of a healthier America, specifically in the areas of better transparency of health care quality information and eliminating inequities in health care.

This year's NHDR and NHQR continue the tracking of trends across a broad array of measures of health care quality and access for many racial and ethnic minority groups and socioeconomic groups. In addition, the 2006 reports incorporate improved measures and methods for summarizing quality and disparities in health care, including new composite measuresiii and expanded analyses of trends in disparities. This section offers a concise overview of findings from the 2006 NHDR. More detailed findings are presented in the chapters that follow.

In the 2006 NHDR, four key themes are highlighted for policymakers, researchers, clinicians, administrators, and community leaders who seek information to improve health care services for all Americans:

Disparities Remain Prevalent

Consistent with extensive research and findings in previous NHDRs, the 2006 report finds that disparitiesiv related to race, ethnicity, and socioeconomic status still pervade the American health care system. Although varying in magnitude by condition and population, disparities are observed in almost all aspects of health care, including:

To quantify the prevalence of disparities across the core measures tracked in the 2006 report, racial and ethnic minority groups and socioeconomic groups are compared with an appropriate reference groupviii for each core measure.ix Each group could receive care that is poorer than, about the same as, or better than the reference group. To facilitate comparisons across racial and ethnic groups, contrasts this year focus on 22 core measures of quality and 6 core measures of access which support reliable estimates for Whites, Blacks,x Asians,xi American Indians and Alaska Natives (AI/ANs), and Hispanics. Comparisons by income group focus on 17 core measures of quality and 6 core measures of access which support reliable estimates by income.xii

For sizable proportions of measures, racial and ethnic minorities and the poor receive lower quality care.

For many measures, racial and ethnic minorities and the poor have worse access to care:

Some Disparities Are Diminishing While Others Are Increasing

The Department of Health and Human Services leads many initiatives aimed at reducing health care disparities and improving health care quality. Many private organizations also work to improve care and reduce disparities. To quantify the success of such efforts to reduce disparities, the 2005 NHDR began tracking changes in core measures over time. This year, methods for tracking trends in disparities have been improved. For each core measure, racial and ethnic minority groups and socioeconomic groups are compared with a designated reference group at different points in time:xix

To facilitate comparisons across racial and ethnic groups, contrasts in the 2006 NHDR focus on 20 core measures of quality and 5 core measures of access which support reliable estimates for Whites, Blacks, Asians, American Indians and Alaska Natives, non-Hispanic Whites, and Hispanics at more than one time point. Comparisons by income group use these same 5 core measures of access. However, the income contrast uses 12 core measures of quality because less information is available by income group for quality measures and only 12 of the 20 core measures of quality support estimates by income group at more than one time point.xx

For racial and ethnic minorities, some disparities in quality of care are improving and some are worsening. For the poor, most disparities are worsening.

To illustrate these changing disparities in the quality of health care, examples include:

For racial minorities, most disparities in access to care that could be tracked are improving; for Hispanics and the poor, most disparities are worsening. Of core measures of access that could be tracked over time:

Opportunities for Reducing Disparities Remain

Although some disparities are diminishing, many opportunities for improvement can still be found. For all groups, measures could be identified for which the group not only received worse care than the reference group but for which this difference was getting worse rather than better.

The 2006 NHDR also finds that Hispanics and the poor faced many disparities in access to care that were getting worse (Table H.2):

Information About Disparities Is Improving, But Gaps Still Exist

New Data Sources and Measures

The 2006 NHDR provides more information about disparities than previous reports. Improvements include the addition of new data sources and new measures that have allowed analyses of new disparities:

Unresolved Information Needs

The expanded capability of Federal data sources has allowed more reliable estimates to be made for more populations. However, considerable gaps remain. Information gaps can relate to insufficient data to produce reliable estimates or, when estimates are possible, to inadequate power to detect large differences.xxvi

For example, of the core measures of quality, statistically reliable estimates were not possible for:

Power issues were also a problem, particularly for American Indians or Alaska Natives, in core measures of access. Data collection that focuses on specific groups may be needed to yield reliable information about these populations.

Of the core measures of access, statistically reliable estimates were not possible for:

Power was insufficient to detect a 20% difference relative to Whites for:

Estimation and power were not problems for Hispanics and the poor, so data are not presented for these groups.

Moving Forward: National Standards, Neighborhood Solutions

The NHDR continues to be the broadest annual examination of disparities in health care ever undertaken in the United States. As support for reducing disparities continues to grow, the ability to monitor and track improvements in disparities is becoming critical. In this 2006 report, the information infrastructure built in previous reports to track the Nation's progress toward the elimination of disparities in health care continues to mature. Multiple years of data are available to assess the direction of change across a large number of measures of health care quality and access.

As mandated by Congress, the NHDR concentrates on the national view of health care disparities. It is descriptive and not prescriptive about how to eliminate disparities. It defines national standards for the measurement of disparities in health care quality and access and provides national baselines needed for tracking progress toward eliminating these disparities.

However, neighborhood solutions are the key for achieving the elimination of health care disparities. Although some barriers to care, such as lack of insurance, affect numerous communities, many causes of disparities and priorities for addressing them vary across the country. Successfully addressing these disparities will require focused community-based projects that are supported by detailed local data. The methods and measures used in the reports are made available online in hopes that communities and providers will apply them to their own data. Communities that make this investment may use NHDR findings as annual national benchmarks against which to compare their progress.

To further support community-based approaches to reduce health disparities that affect racial, ethnic, and underserved populations, AHRQ has developed a variety of information products derived in part from data gathered for the annual production of the NHQR and NHDR. These products seek to translate disparities information for use by State and local health policymakers and include:

For policy makers who are ready to make changes to reduce disparities, AHRQ supports community partnerships that engage public and private stakeholders to improve the quality of care for people with diabetes and asthma, to develop quality improvement action plans, and to evaluate innovative implementations of State and community efforts to improve quality and disparities. These partnerships seek to go beyond research to actively address problems with quality and disparities. They include:

Prevention and elimination of health care disparities for the Nation will result from coordinated actions at Federal, State, and local levels to extend the benefits of regional and community successes nationwide. Working together, using the NHDR as a guide, America's patients, providers, purchasers, and policymakers can make full access to high quality health care a reality for all.


i. Socioeconomic differences include differences in education and income levels.
ii. Facilitators to health care are factors that increase the likelihood that people will get the health care they need, such as having health insurance and a usual primary care provider.
iii. Composite measures provide readers with a summarized picture of some aspect of health care by combining information from multiple component measures. For example, the NHDR composite measure for "complications following surgery" includes measures for persons who develop pneumonia, bladder infection, and blood clots in the legs following surgery.
iv. Consistent with Healthy People 2010, the NHDR defines disparities as any differences among populations. In addition, all disparities discussed in the NHDR meet criteria based on statistical significance and size of difference described in Chapter 1, Introduction and Methods.
v. Preventive care includes counseling about healthy lifestyle behaviors and medical screenings to diagnose diseases at as early a stage as possible. For example, the NHDR includes measures for various screenings, counseling, maternal and child health care, and vaccinations.
vi. Acute care is short-term medical care. For example, the NHDR includes measures for heart disease, pneumonia, and patient safety.
vii. Chronic care is long-term medical care. For example, the NHDR includes measures for nursing home, home health, and hospice care and chronic diseases such as diabetes, asthma, ESRD, and cancer.
viii. For all measures, Blacks, Asians, and American Indians and Alaska Natives are compared with Whites; Hispanics are compared with non-Hispanic Whites; and poor individuals are compared with high income individuals.
ix. For a list of all core measures and the core measures included in these summary analyses, see Chapter 1, Introduction and Methods.
x. The NHDR officially uses the term "Blacks or African Americans" in accordance with the U.S. Office of Management and Budget (OMB). However, the text of the NHDR often refers simply to "Blacks."
xi. "Asian" includes "Asian or Pacific Islander" (API) when information is not collected separately for each group.
xii. Readers will note that findings in the 2006 Highlights suggest a snapshot of disparities similar to that shown in 2005. However, there are some differences, which are in part due to improved methods developed and approved by the HHS-wide Interagency Work Group that advises the NHDR. Specifically, in the 2005 NHDR, comparisons for each racial, ethnic, and income group included all measures with data available for that racial, ethnic, and income group. For example, although data were available for 46 quality measures for Blacks, data were only available for 21 quality measures for AI/ANs. In the 2006 NHDR, a uniform set of quality measures and access measures is analyzed for all racial, ethnic, and income groups. This change should be considered when comparing findings from the 2006 NHDR Highlights versus the 2005 NHDR Highlights.
xiii. Blacks had significantly lower rates of physical restraints among nursing home residents and suicide deaths than Whites.
xiv. Asians had lower rates of late stage colorectal cancers, colorectal cancer deaths, new AIDS cases, suicide deaths, pressure sores among high-risk nursing home residents, and hospitalizations among home health care patients and higher rates of adequate hemodialysis and being on a transplant waiting list among dialysis patients.
xv. AI/ANs had lower rates of late stage colorectal cancers, colorectal cancer deaths, and suicide deaths.
xvi. Hispanics had lower rates of late stage colorectal cancers, colorectal cancer deaths, and suicide deaths and higher rates of adequate hemodialysis.
xvii. "Poor" is defined as having family incomes less than 100% of the Federal poverty level and "high income" is defined as having family incomes 400% or more of the Federal poverty level.
xviii. Poor people had higher rates of needed treatment for illicit drug use.
xix. Consistent with Healthy People 2010, disparities are measured in relative terms as the percent difference between each group and a reference group; changes in disparity are measured by subtracting the percentage differences between the baseline and the most recent year. The change in each disparity is then divided by the number of years between the baseline and most recent estimate to calculate change in disparity per year. Note that statistical significance is not required to label a disparity as improving or worsening; very few changes in disparities over time are statistically significant at the 0.05 level.
xx. As noted earlier, findings for disparities trends in the Highlights of this report suggest the same general trends identified in the 2005 NHDR Highlights. Some differences are noted, which are in part due to improved methods. Methods changes in this report include the following: (1) measures with only a small amount of change may be identified as the "same," whereas last year all measures were identified as "improving" or "worsening" regardless of the magnitude of change; and (2) a uniform set of quality measures and access measures is analyzed for all racial, ethnic, and income groups, whereas last year comparisons included all measures with data available for each racial, ethnic, and income group. These changes should be considered when comparing findings from the 2006 Highlights versus the 2005 Highlights.
xxi. In interpreting these findings it is important to note that there are significant gaps in data availability for AI/ANs.
xxii. This data source collects data for Mexican Americans rather than Hispanics.
xxiii. This survey provides unique insight into end-of-life care and captures information about a large proportion of hospice patients but is limited by non-random data collection and a response rate of about 40%. In addition, race and ethnicity were not reported by large numbers of respondents.
xxiv. Complications following surgery include pneumonia, bladder infection, and blood clots in the legs.
xxv. Note that physician estimates include both physicians born in the United States as well as physicians who immigrated into the United States.
xxvi. "Statistical power" refers to the ability of a test to detect an effect of a given size and is strongly influenced by the sample size of the measurement taken.
xxvii. Readers should consult the AHRQ Web site (www.ahrq.gov) for announcement of availability of the State Snapshots.
