THE NATIONAL ACADEMIES
Advisers to the Nation on Science, Engineering, and Medicine
The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Ralph J. Cicerone is president of the National Academy of Sciences.
The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Charles M. Vest is president of the National Academy of Engineering.
The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Harvey V. Fineberg is president of the Institute of Medicine.
The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy’s purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Ralph J. Cicerone and Dr. Charles M. Vest are chair and vice chair, respectively, of the National Research Council.

Foreword
The Institute of Medicine report Unequal Treatment: Confronting Racial and Ethnic Disparities in Healthcare (2002) called attention to poorer access to health care and worse health outcomes among certain racial and ethnic groups. According to reports from the Agency for Healthcare Research and Quality and others, disparities in the quality of care and in health outcomes persist. Accelerating progress toward eliminating these disparities depends in part on our ability to identify and track experiences in health care among individuals from a variety of racial and ethnic backgrounds and who speak a variety of languages other than English.
This report offers an approach to identifying racial, ethnic, and language categories that bear on disparities in health care and health outcomes. Extending beyond the broad racial and ethnic categories used by the Office of Management and Budget, this report provides a more granular classification of ethnicity and language needs. This standardized approach to classification will both help measure progress in eliminating disparities and assure that comparisons across different settings are based on similar groupings of individuals.
I want to express my appreciation to the subcommittee and staff for the tremendous effort that has gone into this report. Their work represents another positive step toward the goal of high quality health care for everyone.

Preface
Calling attention to the need for improvement in quality of care has been a central theme for many Institute of Medicine (IOM) reports. Crossing the Quality Chasm: A New Health System for the 21st Century noted significant shortcomings in the nation’s health care delivery system in terms of safety, effectiveness, timeliness, efficiency, patient-centeredness, and equity, while Unequal Treatment: Confronting Racial and Ethnic Disparities in Healthcare documented that in a variety of organizational settings and clinical domains, members of racial and ethnic minority groups receive poorer quality care than their White counterparts.
While many studies published since the 2003 release of Unequal Treatment have shown similar patterns, there is evidence of some progress. Disparities in some domains (e.g., process of care measures such as use of beta blockers or aspirin after heart attack) have been shown to be shrinking over time for some populations but not others. Individual health plans, hospitals, and medical groups have organized quality improvement projects aimed at reducing disparities and have succeeded in doing so. The underlying reasons for disparities are increasingly understood so that initiatives to address disparities can be focused on factors that are likely to have the greatest positive effect. The impact of language, culture, and socioeconomic status, along with race and ethnicity, are also more clearly understood. Yet studies reveal that disparities remain on both process of care and outcome measures.
Continued work in addressing disparities requires the collection and use of data on race, ethnicity, and language in all health and health care data systems, as called for in 2004 by the National Research Council report, Eliminating Health Disparities: Measurement and Data Needs. These data provide the opportunity to monitor and analyze disparities, and are informative in identifying individuals and groups to whom quality improvement or other interventions can be directed. Across a range of organizational levels, from the Agency for Healthcare Research and Quality National Healthcare Disparities Report at one end, to the work carried out by individual physician offices and community health centers at the other, the collection and use of data on race, ethnicity, and language are key parts of the process of identifying health care needs and eliminating disparities.
Quality improvement can be organized as a collaborative effort at a local, regional, statewide, or even national level. Even when projects are carried out by individual organizations, the process of benchmarking involves sharing information from organization to organization. For some quality improvement projects, literal data sharing is important, as an entity collecting race, ethnicity, or language data (e.g., a multispecialty group practice) may provide that information to another entity (e.g., a managed care plan) in order for the second entity to use the information for analyses of quality of care data. Additionally, regional, state, and national health care agencies may wish to pool data from individual organizations to address disparities in a broader geographic context.
The collection of data on race, ethnicity, and language will, in principle, have the greatest impact if it is done according to standards that allow for comparison of data across organizations, sharing of individual-level data from one to another, and combining of data from multiple sources. The Subcommittee on Standardized Collection of Race/Ethnicity Data for Healthcare Quality Improvement was asked to examine the issue of how data on race, ethnicity, and language are collected in various contexts associated with health care, and to offer recommendations on standardization of the categories for these variables. This report addresses data collection challenges and proposes a framework for moving forward with standardized data collection across health care entities. Previous reports have reiterated the importance of collecting more detailed ethnicity data than are captured by the Office of Management and Budget (OMB) standard categories; this report proposes templates of granular ethnicity and language categories for national adoption so that entities wishing to collect detailed data can do so in systematic, uniform ways. The recommendations presented here provide guidance to entities on data collection to support their efforts to improve quality and eliminate disparities.
