Page iv THE NATIONAL ACADEMIES National Academy of Sciences National Academy of Engineering Institute of Medicine National Research Council 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. Bruce M. Alberts 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. William A. Wulf 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. Kenneth I. Shine 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. Bruce M. Alberts and Dr. William A. Wulf are chairman and vice chairman, respectively, of the National Research Council.

Page ix Preface After several decades of close attention to the cost of health care and to the uneven access to this care across the United States, we are now beginning to seriously examine health care quality. A wide range of individual studies suggests that the quality of the health care we receive is often less than optimal, if not downright poor. Yet we lack information that would allow us to systematically examine how we are doing, to determine which aspects of our health care are better or worse, and to assess whether the quality of our care is improving over time. To help fill these knowledge gaps, the Institute of Medicine (IOM) was asked by the Agency for Healthcare Research and Quality (AHRQ) to undertake a planning effort for a “national quality report on health care delivery.” In the 1999 legislation that reauthorized and renamed the agency, Congress mandated that such a report be developed and published annually starting in 2003. Specifically, the IOM and the committee appointed to conduct this study were asked to take a long-term view and to suggest how best to measure the overall quality of health care in the nation. We were to develop a format that would allow both policy makers and the general public to make year-to-year comparisons of how the health care system is doing, allowing them to determine just how much the quality of care varies or diverges from desired levels when these are specified. Furthermore, our effort is supposed to encompass the spectrum of health care settings, not just the inpatient hospital environment. Eventually, it is also supposed to allow for state- or regional-level measures, as well as

Page x measures that compare the quality of care received by various racial, ethnic, or other groups in the population. The committee brought together expertise in health care quality measurement, health care financing and delivery, health information systems, communications, health economics, biostatistics, medicine, and public policy, as well as the perspectives of state-level health policy makers and health care purchasers. We met four times and sponsored a workshop on the state of the art in health care quality measurement and reporting that gave us the opportunity to hear from a variety of groups and experts. Through their presentations, we learned about quality measurement in other sectors, international experiences with national health care quality reports, the availability of measures to assess diverse aspects of health care quality, and other technical and policy issues related to quality measurement. The results of these efforts are the following general and specific recommendations to AHRQ on the National Health Care Quality Report. Recognizing that the Quality Report will be a dynamic document, evolving over time and that evaluation of the report and its impact should guide subsequent efforts, we sought to give broad guidance on how to undertake the vital task of assessing the quality of health care most effectively. In addition to offering a framework for thinking about health care quality, we give specific examples of the types of measures the Quality Report should include. We also provide suggestions on the criteria for making decisions about which specific measures to include or exclude and where to obtain that information. Lastly, we provide advice on how to reach the intended audiences with this valuable information. We believe that if properly prepared and communicated, the National Health Care Quality Report can become a mainstay of our nation's effort to improve health care quality. For just as today everyone from the stockbroker on Wall Street to the person in the street follows the economic indicators, someday soon the Congress, executive branch agencies, providers, consumers, and the public at large will be tracking trends in health care quality via the National Health Care Quality Report. We eagerly look forward to that new era. William L. Roper Chair Arnold M. Epstein Vice-Chair

Additional information and insights came from Irma Arispe, Associate Director for Science, National Center for Health Statistics; Edward Sondik, Director, National Center for Health Statistics; other members of the federal intragency working group on the National Quality Report; and the others at the Department of Health and Human Services, the Health Care Financing Administration, and other agencies and organizations who responded to our inquiries. The committee also wants to acknowledge the participants at the workshop on “Envisioning a National Quality Report on Health Care” held on May 22 and 23, 2000, in Washington, D.C. Their important contributions greatly facilitated the committee's thinking on the subject and helped to guide the committee's work.

Those who responded to the committee's call for measures on quality of care also provided very valuable input on potential measures for the Quality Report (see Appendix C). The committee and study staff would like to thank colleagues at the Institute of Medicine for their support throughout this project. Janet Corrigan, Director, Board on Health Care Services, provided guidance throughout the study. We are also grateful for the assistance of Linda Kilroy, Office of Contracts and Grants; Jennifer Cangco and Kay Harris, Office of Finance and Administration; Claudia Carl, Mike Edington, and Jennifer Otten, Office of Reports and Communications; and Sally Stanfield and Dawn Eichenlaub, National Academy
