I would like to thank Susan Blumenthal for inviting me to join you today.

The Clinton Administration considers telemedicine to be an exciting and important application of the National Information Infrastructure. Telemedicine promises to bring improved quality health care to many Americans. As those of you who are in the health care profession know, the U.S. health care system consists of superior doctors, hospitals, and equipment. The irony is that many Americans do not have easy access to such superior care, which is largely concentrated in affluent urban areas.

Telemedicine can help us address the issue of access. In rural areas where a patient and the closest health care professional can be hundreds of miles apart, telemedicine can provide access to health care where little or none had previously been available. In emergency situations, this access can save lives. In addition, telemedicine can improve the delivery of health care by bringing a wider range of services, such as cardiology, radiology, and mental health services, to the underserved.

Telemedicine also brings expanded possibilities in the areas of home health care, patient evaluations, and preoperative meetings with patients. Moreover, new information technologies allow for professional development and education for health care providers.

The Clinton Administration is pursuing several initiatives to promote the development of telemedicine. These activities take place on three fronts:

(1) demonstration projects, (2) policy, and (3) evaluation.

Demonstration Projects

Federal funding of demonstration projects has given telemedicine greater visibility and use. The technology of telemedicine is still immature and it is important to encourage innovation in this area. Through the demonstration projects, the Federal government hopes to be a catalyst for both the generation of new technologies as well as innovative applications of older technologies. The demonstration projects are showing us what certain technologies can do, but we are only beginning to integrate successfully the technology into the practical day-to-day business of providing health care. We need more experience in beta-testing different approaches to telemedicine in the field and evaluating their success.

That is why we are funding telemedicine projects in programs such as NTIA's Telecommunications and Information Infrastructure Assistance Program. Over the past three years, TIIAP has funded a couple of dozen projects that use the NII for health care purposes. Through TIIAP, NTIA is supporting projects that demonstrate the use of low-bandwidth desktop video teleconferencing in physicians' offices, projects that demonstrate the benefits of high-resolution imaging in teleconsultations to emergency rooms, projects that provide public health workers with wireless hand-held computers for use in the field, and many more.

Let me give you a sense of what we are doing. In a densely-populated area like New York City, containing a highly infectious disease such as tuberculosis is difficult. Columbia University, the New York City Department of Health, and the Visiting Nursing Service are partners in an innovative telemedicine project aimed to do just that. They are using a variety of advanced telecommunications and information technologies for tuberculosis (TB) detection, treatment, and prevention. The project has linked the information systems of the three institutions, enabling the electronic sharing of case reports by the different health care professionals that are involved in the ongoing care of TB patients. The project has also employed wireless communication links between visiting nurses in patient homes to health records stored at the hospital. Visiting nurses retrieve lists of patients and relevant data as well as update records while meeting with patients. The project has also automated protocols for detecting new cases of TB. Lab results are automatically analyzed and checked for signs that indicate TB cases. Confirmation of new cases of TB at the Columbia Medical Center automatically triggers e-mail messages to the city health department, which is responsible for tracking the spread of the disease.

Another TIIAP demonstration project illustrates the potential for incredible impact in the area of home health care services for the elderly and disabled. A project in Hays, Kansas, spearheaded by the Hays Medical Center, is providing consistent monitoring of a patient's care by interactively monitoring general health, medication, diabetic condition, blood pressure, diet, hygiene, and mental health status. A small video screen is set up in the patient's house. At prearranged times of the day, the patient turns it on and his or her nurse or doctor appears to monitor the patient's condition and find out how he or she is doing. Use of this type of system can provide enormous financial savings over traditional institutional care, in addition to health benefits. The Hays project notes that nurses can see 15 patients in four hours, whereas a nurse physically traveling from house to house may see only five or six patients in a day. And each televisit costs $36, compared with $135 for a home visit by a registered nurse. Such home health care options are especially valuable in rural areas, where the time and cost of getting to a doctor are often great.

While many of the U.S. telemedicine projects have federal government assistance, the sustainability of the projects without such funds is becoming a reality, due in large part to advances in technology and reduction in costs that make telemedicine more affordable.

Policy

A number of important policy issues have emerged from the demonstrations. If telemedicine is to work, we will need to resolve the critical issues of reimbursement for telemedicine services and restrictions on the practice of telemedicine across state lines and national borders. The Hays project underscored the obstacle presented by rules governing payment for services performed under Medicare -- with notable exceptions for teleradiology and telepathology, only services performed the traditional way -- in person, face-to-face -- qualify for Medicare reimbursement. Private insurers for the most part follow this policy. And Medicaid coverage for telemedicine varies among the states. [These facts make even more valid the joke about how many policy holders agree that health insurance is like wearing a hospital gown. You only think you're fully covered.]

State licensure, which serves the important function of protecting the public from incompetent or impaired practitioners, is also a barrier to the widespread adoption of telemedicine. Most states require an out-of-state physician to obtain a full and unrestricted license before consulting directly with patients in the state. Yet, part of the value of the electronic communication is that it can be used to draw upon expertise from all over the country and world, not just within state borders. This is an international issue as well. It is interesting to note how other countries deal with this issue. For example, both the European Community and Australia have adopted a system of "mutual recognition," in which the licensing authorities voluntarily enter into an agreement to accept legally the licensure of a licensee's home state.

The need for technical interoperability, an issue that arose in our NY/TB project because of the desire to share information among different institutions, has raised another important policy issue that I call "policy interoperability." Increasingly, we are exploring ways of putting information on networks so that all health care providers have access to critical medical information. The advantages are apparent if you consider the example of a person who is in a car accident while traveling far from home. The ability of her health care provider to have access to information about any allergies or chronic health conditions is extremely helpful and even life-saving. But making such information accessible to doctors and other health care providers raises important privacy issues as well as policy interoperability, by which I mean that different hospitals or clinics may have different policies with regard to data protection/confidentiality. To avoid a situation where information is leaked, we need to harmonize such policies. We have seen demonstrations projects where this has occurred, resulting in the successful sharing of highly confidential data.

The privacy of health records is not the only privacy issue raised by telemedicine applications. There are some concerns with respect to interactive long distance video consultations, where it is difficult for the patient at one end to ascertain who else may be watching the session along with the clinician on the other end. In addition, the use of video and other equipment introduces personnel that provide technical support but are also privy to the consultation.

The Administration recently completed a comprehensive look at the these and other telemedicine issues, in a report prepared for Congress. The Department of Commerce, in consultation with the Department of Health and Human Services, authored the report, which focuses on the use of advanced telecommunications services for medical purposes.

Evaluation

In our report to Congress, we also highlight the need for evaluating telemedicine projects. As we engage in the telemedicine demonstration projects, we must take time to step back and ask such questions as --



The answers to these questions are critical in deciding how to spend our resources and whether a hospital or clinic should offer telemedicine services to its patients.

International Implications

Experiements and innovations in telemedicine in the United States, especially in our rural communities, have exciting international implications. Our use of satellites and wireless technologies to overcome rugged terrain, reach isolated communities, and service areas with low population density has direct application in parts of Australia, Africa, China, Latin America . . . . Our next big challenge is to share our expertise worldwide. This will become a more viable path as nations build out their telecommunications and information infrastructures and acquire the capabilities to offer more advanced telecommunications services.

We can share our experiences in two ways. The first is through education, a sharing of the lessons we have learned about what works and what does not. This can be accomplished through international conferences, bilateral talks, or visits by appropriate health care professionals and technicians.

Second, we can participate in telemedicine projects with other nations. A few such projects are in fact already underway. For example, Stanford University has an international telemedicine program that is pursuing several initiatives. The Stanford Health Services has implemented telemedicine at two key links to the Pacific Rim with videoconferencing technology. The first program is a tele-education program with the Makati Medical Center in Manila, the Philippines. Makati physicians select the topic for discussion and an appropriate Stanford specialist prepares and presents a lecture over the system. A second program established a teleradiology/tele-education link between Stanford Health Services and Singapore General Hospital. Digitized x-rays are sent from Singapore to specialists at Stanford for overread. Stanford radiology specialists review the radiological documentation and send a written report to the Singapore practitioner.

Conclusion

There is much to be done before we realize the full potential of telemedicine. The Clinton Administration looks forward to working with both public and private partners to bring improved health care services to all Americans. Thank you.
