According to BCC Research, the worldwide telemedicine market reached $9.8 billion in 2010 and will almost triple to $27.3 billion in 2016. It's clear from these stats that several nations are using the technology to close the gap in healthcare while lowering the cost of treating patients.
In the United States, the Patient Protection and Affordable Care Act, the healthcare law currently being challenged in the Supreme Court, has pushed many healthcare stakeholders to take a keen interest in telemedicine as a way to treat an increasing number of people who'll be seeking health insurance and medical services if the healthcare law remains intact. In fact, the Centers for Medicare and Medicaid Services' Center for Medicare and Medicaid Innovation has been tasked with finding inventive ways to get telemedicine services in use around the nation.

But that's only one of many initiatives underway. The Joslin Diabetes Center, an affiliate of Harvard Medical School, recently announced that it would begin offering telehealth services nationwide in conjunction with American Well, a well-known telehealth services vendor. Joslin's world-renowned expertise in managing diabetes will no doubt benefit countless patients who don't have easy access to endocrinologists.
Dr. Ido Schoenberg, chairman and CEO of American Well, said the collaboration is a taste of the "medicine of the future," where care doesn't necessarily revolve around a hospital. "It's moving away from location-centric to person-centric," Schoenberg told InformationWeek Healthcare. "There are limitations to what you can do online, but you can do quite a lot online."
Last year, American Well teamed with the U.S. Department of Veteran Affairs to provide online behavioral health services to patients in Minnesota and remote oncology consultations to patients in Nebraska. The company has numerous other partnerships with providers and payers, including one with health insurance giant WellPoint, which will make online care services available to members of its affiliated health plans by adopting American Well's Online Care platform.
There's little doubt that partnerships like these are reducing healthcare expenditures. In a separate project, a single veterans hospital in rural Oregon has saved more than $88,000 in travel expenses during fiscal year 2011 by shifting 3,224 patient encounters from in-person visits to telehealth services, according to Tracy Weistreich, associate director for patient care services at the VA Roseburg Healthcare System. The U.S. Department of Veterans Affairs' Northwest Health Network, which includes Roseburg Healthcare, was able to trim upwards of $742,000 from its budget during the same period by facilitating 23,580 remote consultations.
But those advantages must be weighed against the potential harm that may result from patients not having in-person contact with their physicians. Of course, in situations where patients are far away from a clinic or doctor's office, that's never going to happen anyway. And in most scenarios, patients have already been in the doctor's office for an initial physical exam and lab work, so the telemedicine "visit" is often a follow-up consult that only requires video and audio links for the exchange.
But what's required and what's optimal are two different things. There's a good deal of research to show that a clinician's physical presence in the room, along with a simple pat on the back, has therapeutic value. I worry that as physicians cope with the financial and time restraints in the emerging pay-for-performance world, that they'll overenthusiastically embrace telemedicine services and deprive patients of the essential hands-on component of care.
Even a brief look at the research supporting the value of "high-touch" medicine suggests its importance. Dacher Keltner, a professor of psychology at the University of California Berkley, recently summed up some of the data in a lecture on YouTube.
Experiments suggest that non-sexual touch encourages cooperation, makes the person being touch feel safer, and calms cardiovascular stress, Keltner said. Some hospital studies have even found touching premature babies can boost weight by 47%, according to Keltner.
Similarly touching patients with Alzheimer's disease has been shown to cause a precipitous drop in depressive symptoms. And investigators at UC Berkley say that physicians who make eye contact and simply pat patients on the back are starting to see better survival rates for complex diseases.
In the final analysis, the value of telemedicine will depend on whether the advantages of reaching out-of-the-way patients with expert advice outweigh the disadvantages of losing an important ingredient of the doctor-patient relationship, namely hands-on care. Time will tell.
