Acknowledgments

Many individuals and groups assisted the study committee and staff in the development of this report. We particularly benefited from the experience and wisdom of the Technical Advisory Panel (listed after the committee), both as a group and as individuals.

A number of those involved with the federal Joint Working Group on Telemedicine provided information and advice throughout the project. Dena Puskin, Sc.D., chair of the working group and Deputy Director of the Office of Rural Health Policy, was unfailingly helpful with her time and insights. Linda Brink, Ph.D., Chair of the Department of Defense Telemedicine Evaluation Working Group, contributed generously from her evaluation experience. She also arranged an on-site visit to the telemedicine center at Walter Reed Army Medical Center and provided periodic updates on the military's development of evaluation tools and processes.

Michael Ackerman, Ph.D., was a pleasure to work with, both as project officer for this study for the National Library of Medicine (NLM) and as a participant in many key information infrastructure activities. Donald Lindberg, M.D., Director of the NLM and Betsy Humphreys, M.L.S., Deputy Associate Director of NLM Library Operations provided important direction early in planning the study. William England, Ph.D., the project officer from the Health Care Financing Administration, was also very helpful. From the early

days of the study, Colonel Joan Zajtchuk and Brigadier General Russ Zajtchuk of the U.S. Army provided information and other assistance, including invitations to several military telemedicine meetings.

Committee members and staff met with representatives of many organizations and visited several telemedicine projects. Joseph Gitlin, D.P.H., graciously helped to organize our visit to the University of Maryland Medical System and the Baltimore Veterans Affairs Medical Center (VAMC). (He also worked with Melvyn Greberman, a committee member, to arrange discussions with participants at annual meetings of the Radiological Society of North America and the Society for Computer Applications in Radiology.) In Baltimore, we especially appreciated the time Eliot Siegel, M.D., of the VAMC spent with us, providing a very helpful review of their decision to adopt filmless radiology and their internal assessments of the effects on productivity. Richard Alcorta, M.D., and Gene Bidun of the Maryland Institute of Emergency Medical Services System gave us an overview and tour of the organization's headquarters. Deborah Finkelsen, Stephen Schimpff, M.D., Colin MacKenzie, M.D., and Robert Allman, M.D., of the University of Maryland contributed to our education about their activities.

Douglas Perednia, M.D., arranged for the committee to hear from him, Dan Filiburti, Nancy Brown, M.L.S., Tamara Hayes, Ph.D., Jim Wallace, and others about the activities of the Telemedicine Research Center and the research being undertaken at Oregon Health Sciences University. He also arranged for a "televisit" with Catherine Britain of RODEO NET, which provided an unplanned opportunity to experience some of the technical problems that can complicate interactive audio-video conferencing. Peter Kohler, M.D. (a committee member), and Carol Reinmiller kindly enabled the committee to get a broader view of telemedicine in Oregon by arranging meetings with those involved with state telecommunications policy and with educational uses of telemedicine. Participants included Donald Girard, M.D., Paula McNeil, R.N., Lesley Hallick, Ph.D., James Walker, James Elert, John Saultz, M.D., Mark Dodson, Deana Molinari, R.N., M.S.N., and Hersch Crawford.

At the University of Washington, Tara Cannava, M.H.A., arranged a discussion with those evaluating the WAMI Rural Telemedicine Network including Gary Hart, M.D., Peter House, M.H.A.,

Mike Pirani, Ph.D., and Peter West, M.D. Alan Rowberg, M.D., demonstrated some of the technical and practical issues in integrating digital radiology with traditional film-based operations in radiology departments, emergency departments, and intensive care units.

Chris Barnard, M.D., Medical Director of the Stanford Telemedicine Program, showed us the medical center side of some of the University's telemedicine activities and also took us to two of their "remote" sites. Rodney Hawkins, M.P.A., Purna Prasad, M.S., Linda Cook, R.N., Rick Kong, Gerry Shebar provided insights into the strategic, business, engineering, and management aspects of their program. At the Lytton Gardens Health Care Center, we met with Vera Goupille, M.P.H., Peter Pompei, M.D., and Linda Hibbs, R.N., M.P.A. At Drew Health Foundation, we met with administrator Manfred Hayes, M.B.A., Dana Knoll, M.B.A., Bertha Price, L.V.N., and others. An attempt to arrange a video link with the San Jose Medical Group failed because severe storms disrupted telephone communication in the Bay Area, but this experience, again, was instructional.

William Goodall, M.D., of Allina Health System; Ed Hinman, M.D., of Total Health care; and John Santa, M.D., Joanne Zamorra, and Eric Livingston, all of Blue Cross/Blue Shield of Oregon talked with us about telemedicine in different kinds of managed care environments. Robert Thompson, M.D., invited staff to participate in a meeting of the American College of Radiology and National Electrical Manufacturers Association that illuminated some of the difficulties of building on and extending their experience in developing the DICOM standards for radiology.

Francoise Gilbert, J.D., of Altheimer & Gray, Chicago, and Leo J. Whelan, J.D., Legal Counsel, for Mayo Clinic, Rochester, Minnesota, reviewed drafts of the policy chapter, which greatly benefited from their suggestions (although they bear no responsibility for any errors). In addition to helping draft a background paper for the committee, Neil Neuberger provided numerous information resources and contacts. Among others who were helpful in a variety of ways were Richard Bakalar, M.D., U.S. Navy; Roger Shannon, M.D., Veterans Health Administration; Gloria Jones of East Carolina University; Donna Farley, M.H.A., now of the Rand Organization; Suzanne Tichenor of the Council on Competitiveness; Alice Meyer at

md/tv; Barry Rome at VTEL; Sharon Cauchi of Telemedicine and Telehealth Networks; and Ace Allen, M.D., of Telemedicine Today.

Staff within the Institute of Medicine provided assistance in many different ways. Some of those we especially thank include Claudia Carl, Nina Spruill, Mary Lee Schneiders, Mike Edington, Donna Thompson, Richard Julian, and Molla Donaldson. At the Computer Sciences and Telecommunications Board of the National Research Council, first Louise Arnheim and then Jerry Sheehan were the staff liaisons for this project.

Telemedicine—the use of information and telecommunications technologies to provide and support health care when distance separates the participants—is receiving increasing attention not only in remote areas where health care access is troublesome but also in urban and suburban locations.

Yet the benefits and costs of this blend of medicine and digital technologies must be better demonstrated before today's cautious decision-makers invest significant funds in its development.

Telemedicine presents a framework for evaluating patient care applications of telemedicine. The book identifies managerial, technical, policy, legal, and human factors that must be taken into account in evaluating a telemedicine program. The committee reviews previous efforts to establish evaluation frameworks and reports on results from several completed studies of image transmission, consulting from remote locations, and other telemedicine programs.

The committee also examines basic elements of an evaluation and considers relevant issues of quality, accessibility, and cost of health care.

Telemedicine will be of immediate interest to anyone with interest in the clinical application of telemedicine.
