Steering committee members, panelists, and Institute of Medicine staff officers gratefully acknowledge the contributions of a number of persons who helped significantly in reviewing material that eventually was synthesized into this committee report. Special recognition is clue Sandra Putnam, of the Rhode Island Department of Health, for her major contributions to Chapter 14, ''Treatment Costs, Benefits and Cost Offsets.'' Similarly, Robert Saltz, of the Pacific Institute for Research and Evaluation, served as a consultant on several of the areas encompassed in the first section of the report on prevention research and epidemiology.

In addition to Drs. Putnam and Saltz, several other consultants to the study provided assistance that was greatly appreciated:

John Buckner, School of Hygiene and Public Health, The Johns Hopkins University

Mary R. Casement, Rockville, Maryland

Diana Cassady, University of California at Berkeley

Zelig Dolinsky, University of Connecticut Health Center

Michael Hofmann, Commission on Hospitals and Health Care, Hartford, Connecticut

Jonathan Howland, Boston University School of Public Health

The committee benefitted from the guidance offered by Barbara Filner and Ruth Bulger of the Institute of Medicine's Division of Health Sciences Policy; they initiated and supervised this project in its early phases. Special thanks also are due Kenneth Warren, Director, Office of Scientific Affairs, National Institute on Alcohol Abuse and Alcoholism (NIAAA). In his capacity as NIAAA project officer for this study, Dr. Warren has been both personally and professionally very supportive of the committee's efforts.
