NOTICE: The project that is the subject of this report was approved by the Governing Board of the National Research Council, whose members are drawn from the councils of the National Academy of Sciences, the National Academy of Engineering, and the Institute of Medicine. The members of the committee responsible for the report were chosen for their special competences and with regard for appropriate balance.
This report has been reviewed by a group other than the authors according to procedures approved by a Report Review Committee consisting of members of the National Academy of Sciences, the National Academy of Engineering, and the Institute of Medicine.
The Institute of Medicine was chartered in 1970 by the National Academy of Sciences to enlist distinguished members of the appropriate professions in the examination of policy matters pertaining to the health of the public. In this, the Institute acts under both the Academy’s 1863 congressional charter responsibility to be an adviser to the federal government and its own initiative in identifying issues of medical care, research, and education. Dr. Kenneth I. Shine is the president of the Institute of Medicine.
Support for this project was provided by funds of the National Research Council and the Institute of Medicine (The W. K. Kellogg Foundation). Partial support was also provided by the Bureau of Health Professions of the Health Resources and Services Administration, U.S. Department of Health and Human Services, under Purchase Order No. 103HR960824P000-000. The views presented are those of the Institute of Medicine Committee on the U.S. Physician Supply and are not necessarily those of the funding organization.

Preface
The U.S. health care system is in a period of enormous change. Catalyzed by market forces rather than government-initiated reforms, these changes are fundamental and are occurring rapidly. Although it is difficult to predict what the system will look like when a period of stability is reached, it is clear that the changes being made in its organization and in the financing of health care will have an impact on all components of the health care workforce. The numbers and types of health professionals required and the roles of each health profession will surely be much different in the future than in the past.
This study by the Institute of Medicine (IOM) is the result of a number of widely held concerns about the size of the U.S. physician workforce and the direction in which it is moving. Despite numerous studies in the past 15 years, which have indicated that the U.S. physician supply will exceed requirements, the number of doctors in residency training has continued to grow each year. At the same time, there is evidence that the demand for physician services will be reduced as a result of the growth of managed care. All of this is taking place at a time that the United States has no coordinated and widely accepted physician workforce policy, as had been laid out during the period that comprehensive health care reform at the national level was being debated.
Sensing that the nation was drifting in terms of a sound, defensible approach to its physician workforce needs and recognizing that a physician surplus carried at least the potential for adverse consequences, the IOM elected to undertake a short and focused study of the aggregate U.S. physician supply. The limited scope of the study should not be construed to imply the absence of other important physician workforce issues, such as specialty and geographic mal-
distribution or lack of diversity. These problems are far from solved and must be addressed in their own right.
The present study was designed to examine three questions:
-
Is there an aggregate physician surplus?
-
If there is a surplus, what is its likely impact on cost, quality, and access to health care and on the efficient use of human resources?
-
What realistic steps might be taken to deal with any surplus that exists?
A broadly representative IOM committee met on a single occasion to discuss these questions. Prior to the meeting, committee members were provided with an extensive series of relevant articles from the published literature and a background paper prepared by IOM staff. It is a tribute to the hard work of both committee members and Kathleen Lohr, Director of the IOM Division of Health Care Services, who staffed the study, that so much consensus on the three questions could be reached in the short time available.
It is our hope that this report will stimulate renewed interest in physician supply issues and catalyze efforts to resolve the problems it identifies.

Acknowledgments
At its single meeting in July 1995, the committee profited greatly from thoughtful and informative presentations from two experts in this field—John Eisenberg, M.D., Chairman and Physician-in-Chief, Department of Medicine, Georgetown University; and Fitzhugh Mullan, M.D., Assistant Surgeon General and Director of the Bureau of Health Professions of the Department of Health and Human Services—and it wishes to express its deep appreciation for their efforts. Also very helpful were other staff of the Health Resources and Services Administration, including Carol Bazell, M.D., the government's project officer for the Bureau of Health Professions, Philip Salladay of the Bureau of Primary Health Care, and Robert Politzer, Chief, Workforce Analysis and Research.
The committee also acknowledges the considerable assistance rendered to this project by several members of the Institute of Medicine (IOM) staff. Molla Donaldson, a senior staff officer, was generous in sharing materials and insights from a related study on primary care. Holly Dawkins, research assistant at the IOM, helped with checking facts and improving the manuscript at a key juncture. Moeen Darwiesh, the IOM's computer specialist, and Nina Spruill, the financial associate for the Division of Health Care Services, rendered key assistance when most needed. Finally, Don Tiller, the division's administrative assistant, graciously undertook to be project assistant at a time when he was already fully occupied.
