The Rising Tide of Mobile Medical Device Innovations, Sparked by Mobile IPhone, Tablet Computers, and Wireless Sensors

You can never tell what innovators will do when left to their own devices.

October 29, 2012 -   Hold your breathe.  We are about to enter a fast-paced  new chapter on the use of  Iphone generated ,  wireless sensors, tablet-transmitted  medical innovation.  Apple’s IPhone series started the stampede,   Samsung, Motoral , Amazon, Google, and Microsoft, which just introduced it Windows 8 device, are in the hunt. 

Where the wireless high-speed bandwagon will go, no one knows. But several things are certain.

The new devices and apps will allow:

·         Physicians to monitor  patients at a distance – for routine checkups, for  function of implanted or wearable devices,  for condition en route to the hospital whether  they be on stretchers or in emergency vehicles.

·         Patients to monitor themselves from home or work or during travel. At home or abroad.

·         Cardiologists to look directly into the heart  and to view its muscles, valves, muscles,  and rhythm.

·         Doctors to view images of MRIs,  CT scans, and electorcardiograms

One another note.  This is not the first time I have commented on mobile devices, 

Here is a previous blog I wrote on the subject dated December 12, 2011

Frugal Health Reform Innovation

He who does not economize will agonize.

Confucius (551-479 B.C.)

Preface: Anthony Regalado, business editor of the MIT Press’ Technology Review (http://www.technology review.com/business/39216) sent me the following article, which will appear in Technology Review today.

The author of the article is Eric J. Topol, Chief Academic Officer of Scripps health. It is an important contribution to the health care innovation debate. Topol is also author of The reative Destruction of Medicine: How the Digital Revolution Will Create Better Health.

"Medicine Needs Frugal Innovation,"  Technology Review

“A low-cost pocket ultrasound device can see into the human heart. So why do so few doctors use it?”

“In the history of medical innovation, advances in technology have been inextricably linked to increases in cost. But we are at a unique moment in which the insular world of medicine is about to be penetrated by the remarkable digital infrastructure. Think about the cost of computing. Over the past two decades, cost has been relentlessly reduced while capacity and performance have dramatically increased. How and when can this trend reach the practice of medicine, where costs often go up with little real improvement?”



“Let's consider the icon of medicine—the stethoscope draped around the doctor's neck or in the pocket of a white coat. Invented by René Laënnec in 1816, the stethoscope didn't see routine use by the medical community for another 20 years. The lag in acceptance reflected the conservative nature of physicians, who objected to having to learn heart sounds and let an instrument get between their healing hands and the patient. “

“Now, nearly 200 years later, economic forces are greatly slowing the adoption of a powerful replacement for the stethoscope in cardiac medicine. Instead of listening to the heart of a patient, I can now watch it on a device no bigger than a cell phone—a high-resolution miniature ultrasound probe. In fact, in my clinic I have not used a stethoscope to examine a patient's heart for the past two years. “

“Why would I listen to the "lub-dub" of heart sounds when I can actually see everything relevant about the heart in real time? Exquisite ultrasound images of the heart muscle—showing its contraction, its thickness, the size of the chambers, the valves, the sac around the heart—can all be obtained within seconds as part of a routine physical examination. I can share and discuss the images with the patient as they are being acquired, put video recordings in the electronic medical record, and send them to the patient or referring physician. The up-front cost of the pocket ultrasound device is about $7,700, but there is no extra cost for an unlimited number of readings. “

“That makes these small devices a formidable challenge to business as usual in American health care. Each year in the United States more than 20 million echocardiograms (ultrasounds of the heart) are performed, and so are a similar number of abdominal and fetal ultrasound examinations. Each of these diagnostic procedures is done in a dedicated laboratory setting, either in the hospital or in a doctor's office, with expensive equipment—and a combined professional and technical charge of $1,000 to $2,000. The math is straightforward. If a pocket ultrasound device were incorporated into routine physical exams the same way we use a stethoscope, several billion dollars in unnecessary charges would be saved each year.”

Therein lies the rub—and the explanation for why many low-cost innovations are being held back in medicine. Those savings would represent a critical hit to revenue for doctors and hospitals. It's not just that doctors, like those who refused to use the stethoscope, are intrinsically conservative. The American health-care model of billing "medicine by the yard" creates economic disincentives to cost-saving technology. In contrast, pocket high-resolution ultrasound has been rapidly adopted and hailed as a breakthrough in countries such as India, China, and Brazil.”

“This represents just a single, simple example of how frugal innovation—the idea of coupling engineering creativity with lower costs—could be achieved if patient care in the United States were not determined by reimbursement rules. We now have wireless sensors that can help us diagnose sleep apnea by capturing all the relevant data for sleep studies—respiratory rate, oxygen saturation of the blood. The data can easily be captured for less than $100, right in a patient's home. But instead, the medical community keeps using $3,000-per-night hospital sleep labs to make the diagnosis.”

“I believe a great inflection is coming in medicine: advances in technology will finally help us override the reimbursement issue and topple the economic models that physicians, insurers, and hospitals still cling to. This moment will arrive as medicine is opened to the digital infrastructure of mobile wireless devices, pervasive connectivity, ever-expanding bandwidth, cloud and supercomputing power, and the Internet. “

“Superimposed on these digital capabilities are the ones specific to health care—genomic sequencing, biosensors, advanced imaging, and health information systems. It will all lead to what I call "high-definition man": a panoramic, granular profile of an individual's molecular biology, physiology, and anatomy.”

“Medicine, in short, has the potential for better technology at a much lower price, but don't look to the medical profession, government, or the life-sciences industry to make the change on its own. I believe the change will come when consumers demand it. The Arab Spring and the Occupy Wall Street movement have shown the influence of social networks as a way to express citizens' demands. Don't be surprised if health care is occupied next. “

Fitting and Proper Close

It is altogether fitting and proper that I close with this perverse verse.

When with new technologies, you no longer need a stethoscope,

You can use new technologies as an endoscopic periscope,

To see with what diseases you must cope,

At the other end of the diagnostic rope.

Technologies, unfortunately, can be abused,

And simple human observations underused.
