Are the stars aligning for telemedicine's succcess?
The current health care crisis has some experts saying that telemedicine's time has finally come.
While technology companies have been touting the use of virtual technology to allow doctors to remotely examine and monitor patients for decades, up until recently the business case for deploying these expensive systems was hard to justify. But now as lawmakers in Washington, D.C. look for ways to fix the broken health care system, technologies, such as high-definition video conferencing and telepresence, are getting a second look.

The program will initially focus on providing people in remote and under-served areas with health care. But Cisco and UnitedHealth representatives say eventually the program could be expanded throughout the country.
Part of the reason that telemedicine hasn't taken off in a big way in the past has been cost. While technologies, such as telepresence may eventually reduce the cost of providing health care services, initially they are expensive to deploy. For example, Cisco's high-end telepresence conferencing system that is sold to large companies to replicate a boardroom costs upward of $300,000.
And because these systems require the use of high-definition audio and video, which must be transmitted over an Internet connection between doctors and patients, these systems require significant amounts of bandwidth. This means that without ubiquitous broadband access throughout the country, the cost benefits and usefulness of the technology is limited.
Still, the rising cost of health care and predictions that these costs could cripple the nation, have increased the urgency for nontraditional solutions. This change in attitude coupled with the Obama administration's plan to reform the health care system has stirred more interest from almost every big technology company in the country.
Intel and General Electric are working on a home monitoring system. Google and IBM have also announced an in-home system that transmits data from devices such as blood-pressure cuffs and glucose meters via the Internet. And Cisco and Polycom have retrofitted their corporate telepresence systems to provide near-real-life interaction between patients and doctors.
And they all believe that the health care industry is finally ready to spend big bucks on expensive new technologies today to help stem rising costs for tomorrow.
"What is different right now is that the health care system in this country is being asked to deliver service more effectively and efficiently without increasing the available resources," said Nick Augustinos, senior director with Cisco's Internet Business Solutions group for global health. "So what's needed now is a health care system that can scale. And that is what telepresence and other remote monitoring technologies can do by extending the natural reach of doctors and clinicians in a nontraditional way."
The partnership between Cisco and UnitedHealth is an important milestone in the telehealth movement because the companies will be working together to solve not only the technical and clinical hurdles that come with deploying this technology, but they will also be trying to solve the business problems for delivering health care.
"This is why we partnered with an insurance company, so that we could understand the business model to build a solution that will deliver effective, efficient care at a lower cost," Augustinos said. "And the truth is that if we didn't approach it that way, then we'd have wonderful technology that could provide excellent care to lots of people, but no one would want to buy it because they wouldn't want to pay for it."
One of the challenges in deploying telemedicine has been the fact that insurance companies have been more likely to reimburse traditional face-to-face doctor visits rather than procedures done remotely using telemedicine. But with the partnership between UnitedHealth Group, which insures some 70 million people in the U.S. and Cisco , it looks like insurance companies may be realizing the economic benefits of scaling the health care system virtually.
"Health care is a business," said Bob Preston, vice president of solutions marketing at Polycom, another major telepresence provider in the health care market. "And if medical groups and health insurers can offer services to more patients via telepresence, while reducing their costs, they can increase their revenue."
Using high-definition cameras and monitors, telepresence technology creates a "conferencing" experience that is so intimate people think they are in the same room with the people on the other end of the teleconference. Cisco and Polycom, two of the leading telepresence equipment providers on the market, have adapted technology they developed for large companies for use in medical environments.
Typcially, these solutions are scaled-down versions of the high-end telepresence systems, but they also include adapters for medical devices that can provide vital sign monitoring, such as blood pressure, pulse rate, oxygen saturation and temperature, as well as interfaces for stethoscopes and otoscopes for examining ears.
Cisco has designed its "HealthPresence" system as a small telepresence room, or "pod." And Polycom offers a variety of products that range from full telepresence rooms to a mobile telepresence cart that can be wheeled from room to room in a hospital or clinic.
The way it works is that a doctor sits on one side of the telepresence connection, while a medical professional mans the booth or cart on the patient side of the connection. This technician sets up the call and uses the medical equipment to examine the patient as directed by the doctor.

The doctor can control the camera to zoom into different parts of the body. At the same time, electronic medical records and other data can be viewed by the doctor on a separate computer screen.
While high-definition cameras and screens have made it possible to diagnose many illnesses and injuries, there are still limitations. For example, the experience doesn't allow doctors to actually touch patients, which in some circumstances can help them more accurately diagnose an illness or injury. But for many minor injuries and ailments, telemedicine works very well, experts say.
Depending on the type of service that is being offered, the professional on the patient side of the call could be a trained technician, or he or she could be a registered nurse or general practitioner doctor.
"Nurses and doctors are in short supply in some places, so depending on what level of care that is being provided, the HealthPresence system can be manned by less expensive resources," Cisco's Augustinos said. "By using a lower cost professional or technician, the insurer or medical group providing the service can maximize their resources."
The private medical group NuPhysicia is using Polycom's mobile Practioner Carts to provide walk-in health services at Houston-area Wal-Mart Stores. Instead of using higher paid nurse practioners at the retailer's clinics, the group is using paramedics and remote doctors over the telepresence system to see patients.
The first implementation of the Cisco/UnitedHealth Group partnership is to provide a mobile medical service called Connected Care. Working with an organization called Project HOPE, Connected Care will have a mobile truck or van that travels through four counties in New Mexico offering basic health screenings and treatment for chronic ailments, such as diabetes.
Cisco and UnitedHealth Group have already tested their Connected Care program with Cisco's own employees. In a pilot program launched last year, more than 300 Cisco employees in the company's San Jose, Calif., headquarters used primary-care physicians in Los Angeles via the telemedicine system. Now the companies have expanded the trial to Cisco's Raleigh, N.C., campus where 4,000 employees will have access to five primary care physicians in Cisco's corporate health care center in San Jose.
These trials follow another pilot program that Cisco conducted last year at the Aberdeen Royal Infirmary in Scotland. So far the results have been good. In addition to Cisco's own employees being satisfied with the service, Cisco reported last week that roughly 93 percent of people who received care via the telepresence system in the Aberdeen trial said they would recommend the service to someone else.
Polycom's telepresence gear has also been used to serve people in rural communities. The Cherokee Health Systems has been using the mobile telepresence system to provide medical care to 17 rural school clinics in Tennesse with only two nurse practitioners. And NuPhysicia has used Polycom gear to provide medical care to workers on offshore oil rigs.

(Credit: Polycom)"There is a huge shortage of general practitioners especially in rural areas," Polycom's Preston said. "And as the population ages and people become more immobile, telepresence solutions can help provide access to doctors to people who would otherwise have to travel long distances to see someone."
But Cisco's Augustinos points out that telemedicine is not just for providing medical services to people living in remote areas. It can also be used in urban settings where access to health care professionals is readily available, but where patients must sit in waiting rooms for hours to be seen because demand is so high.
Using presence technology, the Cisco HealthPresence product allows doctors to search the database in a given medical group or ecosystem to find a doctor or specialist anywhere in the country who is available at that moment to see a patient. This allows for a more efficient and cost-effective way to run an urgent care clinic that often sees walk-in patients.
Augustinos explained that the concept is similar to using an 800 number to contact a any service provider's customer support. People call the number, and they are asked to identify the problem or issue they're having so the call can be routed to appropriate pool of operators.
In this case, patients willing to see the first available doctor would be triaged and a doctor, who meets the patients criteria, would be contacted via video-conference to examine the patient.
Another scenario where HealthPresence is useful is when a doctor is examining a patient in his or her office and if he detects a problem during an examination that requires consultation with a specialist, he can look to see who is available in the network. Instead of writing a referral and having the patient schedule an appointment with a specialist, the doctor can dial-in the available specialist for the consultation right then and there.
Augustinos believes that using telemedicine in this way can help lower overall medical costs.
"The thing that drives prices up is an imbalance between supply and demand," Augustinos said. "But if you can more efficiently distribute the resources that exist and optimize those resources, then you can flatten the pricing curve."
But he admitted that no technology, whether it comes from Cisco or anyone else, will be a magic pill to solve all of the health care system's problems.
"We won't solve every ill in health care industry," he said. "But we are suggesting that if you optimize the scarce clinical resources that are available today, you can use the money that is put into the system more efficiently. And that is a start."

Well, if you're noticing enrollment at med schools dropping in the last year, you may see the beginnings of one.
With ludicrous settlements and a sue-happy tendency for patients and judges, prices for malpractice insurances are driving doctors out of a large number of states. It's just too expensive to do business as a doctor there.
Add in the prospect of a single-payer, nationalized health care system, which is doomed to continue the practices of Medicare which stiff the doctor if they ever do pay him his lower-than-market, gov't.-set fee, and there seems to be no monetary draw to join the field and take on all of that student loan debt.
If there is a coming healthcare crisis, it's not a lack of affordable insurance options, it's a lack of doctors, though a *single-payer* system may change the former into one as well.
Proprietary HD hardware (costing $25,000 to $250,000 per location) and the significant bandwidth required to feed it will limit the use of telemedicine to a select group of federally funded academic institutions. Broad access to telemedicine services will only be possible when the cost per location is drops below $200. Using consumer grade webcams and bandwidth, combined with hosted telemedicine applications (SaaS / ASP), telemedicine would be able to move beyond the ?grant gravy train? and provide cost effective solutions actually improving the quality of interactive care.
How ever in highly fragmented market that currently exist in America where no one controles the cost of anything and where they are all looking to make more money than the other doctors, I doubt it will bring down the costs overal.
In fact the artical already mention using lesser trained staff to run these systems.
Also I still think there a lot of progress that is needed in the diagnostic tools available to the adverage patent in there home I got the feeling this will remain niche market which goes no further than the current NHS direct in the UK.
What they need to invent in a tri quarter and affordable holographic systems. I suspect we are at least 30 years from practical and affordable versions of this technology for the averaged home.
What ever the case it seem every country is struggling to make the sums add up when it comes to the health care, some are self denial France, some to entrench to change America, and others like the UK got a rubbish government which take years to make a decision and they do it usally so poorly implemented that it end up cost ten times what they planned for it to cost in the first place, especially when it come to IT systems,
This campaign will dramatically change the minds of those who view telemedicine as unaccessable and will save Americans billions of dollars a year on both doctor and emergency room visits.
Thank you.

Instead of trying to solve the problem at hand head on you guys are trying to make another buck off of it... Ever consider universal health care... a system where everyone pays and people only use it when they're sick so the premiums from healthy people pay for the sick and elderly? I know sounds like a pipe dream right??
Try looking at how some of the European nations do it or even close to home Canada.. ya that country up north? They don't just live in igloos all year round.
The truth is Canadians who can afford it go to the US for medical care. My friend's dad was having kidney issues and was put in a 4 month waiting list (!) to see a specialist. He went to the US, saw a specialist who did a biopsy. Turns out it was cancerous (malignant) and he was in surgery the next day. Had he waited 4 months in Canada it might have been too late.
Even our MPs (Member of Parliament) go to the US for health care. When Liberal MP Belinda Stronach was diagnosed with breast cancer did she trust the Canadian system? No, she went to California for surgery. Imagine that, a sitting Federal MP opting for the US system instead of Canada's own.
The irony is one of the cancer-facilities here in Canada was named after her family, yet she still opted to go to the US for treatment. Another irony is that a first-class cancer facility like the one Stronach went to in California is illegal here in Canada, where the government has a monopoly on care (which only benefits Canadian union workers).

- We have a Polycom rig at our regional rural hospital. it is basically an expensive webcam that works using IP-addresses based connections. It is great for the Emergency Room for quick ER consults to a university emergency consultant, and for ER consults to a subspecialist we might not have at our hospital (if we can find one willing to do Telemedicine consults, which is rare).

(12 Comments)It only rarely gets used.
The problem is payment for Telemedicine services. Insurance companies don't pay for it, and it is very expensive to have Telemedicine consultants available 24/7/365.
The problem, indeed, is the insurance companies. It is amusing that they are supposedly supporting the technology.
Most Telemedicine between family practitioners (and many other practitioners) and their patients only requires a good webcam anyway, and Skype (or other widely available Teleconferencing program). Of course, a good electronic medical record system (such as WorldVistA) is desirable to make recordkeeping efficient.
Patients can use a $30 home blood pressure cuff from Walmart and read the numbers to their doctor -- there is no need for some expensive high-tech telemedicine equipment solution for most consumers.
Complex exams (needing specialized equipment) almost always require in-person consults, anyway. Telemedicine is really only to screen (the majority of) patient encounters that are trivial, don't require extensive exams, or to triage problems, so that recommendations as to where the patient ought to go next (ER, specialist, in-person exam) can be determined. Believe me, those "simple" services comprise about 75% of a family practitioner's business and can almost always be accomplished through Telemedicine.
Of course, insurance companies do not reimburse for this type of interaction at all. A savvy practitioner would set up PayPal on their website, where a patient desiring a Telemedicine consult would have to pay prior to a Telemedicine consult.
Such a system is easily configurable using open source solutions (such as a Drupal-based website).
More specialty-specific requirements, such as remote EKG monitoring, has been done for over a decade anyway, using (now) relatively inexpensive solutions. The results only need to be integrated into an EMR, such as can already be accomplished using more robust EMRs (such as the VA's VistA-based systems).
If you want to keep it inexpensive, keep it simple and don't reinvent the wheel. Also, don't invent what is not likely to be used. But don't take my advice. Ask your doctor.
