CASE: Brain Saving Technologies, Inc. and the T-Health Institute: Medicine Through Videoconferencing.
On average, every 45 seconds, someone in the United States suffers a stroke, the third-leading cause of death as well as the leading cause of permanent disability in the nation, according to the American Heart Association. The first three hours after a stroke are critical to a patient’s survival and recovery. For instance, depending on the type of stroke suffered by a patient, certain drugs can vastly improve the patient’s survival and chances for full rehabilitation. Those same drugs, however, can be deadly if given to a patient suffering another type of stroke. Due in part to a shortage of specialty physicians trained to accurately diagnose and treat stroke victims, not all U.S. hospitals have the expertise and equipment to optimally care for stroke patients, particularly in the critical early hours. The new Neuro Critical Care Center, operated by Brain Saving Technologies Inc. in Wellesley Hills, Massachusetts, will begin to connect emergency-room doctors at a number of suburban hospitals in the state with a remote university hospital that will act as a ‘hub’ with on-call critical-care neurologists who can assist in making remote diagnoses and treatment recommendations for suspected stroke patients, says Stuart Bernstein, CEO and chief operating officer at Brain Saving Technologies. The connection occurs through a visual-communication workstation that can connect via IP, high-bandwidth communications, or private leased line. The workstation allows the remote specialists to examine and talk to patients, and collaborate with on-site doctors to improve timely diagnosisof strokes and optimize treatment options, Bernstein says.
“Our purpose is to provide member hospitals with a major hospital stroke center, 24 by 7,” Bernstein says. CT scans-digital images of patient’s brains-can also be transmitted from the member hospitals to the Neuro Critical Care Center specialists to improve diagnosis of the patients, he says. The images are seen simultaneously by doctors at both locations so that they can collaborate. The technology can also help train emergency-room doctors about what characteristics to look for on the CT scans of stroke patients.
A key component of the Neuro Critical Care Center’s offering is the Intern Tele-HealthCare Solution from Tandberg, which provides simultaneous audio and video transmission and bidirectional videoconferencing and image-display capabilities to hub and member hospital doctors. Emergency-room doctors can wheel the mobile Tandberg system to patients’ bedsides, Bernstein says. Tandberg’s medical video-communication products are also used in other telehealth applications, including situations where doctors need an expert in sign language or a foreign language to communicate with patients or their family members, says Joe D’Iorio, Tandberg’s manager of telehealth. ”
The technology provides real-time visibility and collaboration to help assess patients’ well-being and facilitate real-time interaction,” he notes. Doctors have long had a tradition of holding “grand rounds” to discuss patient cases and educate aspiring physicians. The centuries-old practice certainly has its merits, but medical leaders in Arizona want to improve, update, and broaden it to include a larger list of health care practitioners, such as nurses and social workers, regardless of their locations. So the Arizona Telemedicine Program (ATP) drew on its extensive use of videoconferencing equipment to develop the Institute for Advanced Telemedicine and Telehealth, or the T-Health Institute, to facilitate a 21st-century way of teaching and collaborating across disciplines and professions. “Its specific mission is to use technology to permit interdisciplinary team training,” explains Dr. Ronald Weinstein, cofounder and director of the ATP. “Now we’re opening it up to a far broader range of participants and patients.” The T-Health Institute is a division of the ATP, which Arizona lawmakers established in 1996 as a semiautonomous entity. The ATP operates the Arizona Telemedicine Network, a statewide broadband health-care telecommunications network that links 55 independent health care organizations in 71 communities.
Through this network, telemedicine services are provided in 60 subspecialties, including internal medicine, surgery, psychiatry, radiology, and pathology, by dozens of service providers. More than 600,000 patients have received services over the network. Project leaders say the goal is to create much-needed discussion and collaboration among professionals in multiple health care disciplines so that they can deliver the best care to patients.
“It’s the effort to be inclusive,” Weinstein says. “Medicine is quite closed and quite limited, but we’re counting on telecommunications to bridge some of those communication gaps.” The institute is essentially a teleconferencing hub that enables students, professors, and working professionals to participate in live meetings. Its technology also allows them to switch nearly instantly between different discussion groups as easily as they could if they were meeting in person and merely switching chairs.
Gail Barker has noticed that participants who don’t speak up during in-person meetings often become much more active in discussions held via videoconferencing. Perhaps it’s because they feel less intimidated when they’re not physically surrounded by others or because the videoconferencing screen provides a buffer against criticism, says Barker, who is director of the T-Health Institute and a teacher at the University of Arizona’s College of Public Health. When used poorly, videoconferencing can be stiff and dull, just a talking head beaming out across cyberspace without any chance to engage the audience. But Barker and others are finding that when the technology is used in a thoughtful and deliberate manner, it has some advantages over real-life sessions because of its ability to draw more participants into the fray.
“It’s literally a new method of teaching medical students. It’s a novel approach,” says Jim Mauger, director of engineering at Audio Video Resources Inc., a Phoenix-based company hired to design and install the videoconferencing equipment for the T-Health Institute. The T-Health Institute uses a Tandberg 1500 videoconferencing system, and its video wall has 12 50-inch Toshiba P503DL DLP Datawall RPU Video Cubes. The video wall itself is controlled by a Jupiter Fusion 960 Display Wall Processor utilizing dual Intel Xeon processors. The Fusion 960 allows the wall to display fully movable and scalable images from multiple PC, video, and network sources. Although Weinstein was able to articulate this vision of interprofessional interaction-that is, he could clearly lay out the user requirements-implementing the technology to support it brought challenges, IT workers say. Mauger says creating a videoconferencing system that linked multiple sites in one video wall wasn’t the challenging part. The real challenge was developing the technology that allows facilitators to move participants into separate virtual groups and then seamlessly switch them around.
“The biggest challenges to making this work were the audio isolation among the separate conference participants as well as fast dynamics of switching video and moving participants to meetings,” he explains. He says his team also encountered other challenges-ones that affect more typical IT projects, such as budget constraints, the need to get staffers in different cities to collaborate, and the task of translating user requirements into actionable items. “It’s necessary to have someone there on-site who understands all the complex parts of the project,” he says. “Someone who is not just meeting with people every now and then, but someone who works with them on a daily basis.”
Barker, who teaches in the College of Public Health at the University of Arizona and is a user of the system, led a trial-run training session at the T-Health amphitheater. She met with 13 people, including a clinical pharmacist, two family nurse practitioners, a senior business developer, two program coordinators, a diabetes program case manager, and an A/V telemedicine specialist. For that event, Barker says the biggest benefit was the time saved by having the facility in place; without the T-Health Institute, some participants would have had to make a four-hour round trip to attend in person. Now the system is opening up to others in Arizona’s health care and medical education communities. T-Health Institute officials say they see this as the first step toward a health care system that truly teaches its practitioners to work together across professional disciplines so that they can deliver the best, most efficient care possible. “We think,” Weinstein says, “that this is the only way you’re going to create coordinated health care.”
CASE STUDY QUESTIONS:
1. From the perspective of a patient, how would you feel about being diagnosed by a doctor who could be hundreds or thousands of miles away from you? What kind of expectations or concerns would you have about that kind of experience?
2. What other professions, aside from health care and education, could benefit from application of some of the technologies discussed in the case? How would they derive business value from these projects? Develop two proposals.
3. The deployment of IT in the health professions is still very much in its infancy. What other uses of technology could potentially improve the quality of health care? Brainstorm several alternatives.
