In health technology, an enthusiasm gap between startups and doctors

Dr. Eric Topol is a cardiologist who doesn’t use a stethoscope. As a keynote speaker at a mobile-health convention near Washington, Topol took the stage and performed an echocardiogram on himself using an iPhone. He later reached under his shirt and gave himself an ultrasound using a hand-held device called a Vscan and some hotel-room lotion (he forgot his ultrasound gel). “I once diagnosed a patient who was having a heart attack on an airplane,” Topol said. He explained his passion for portable health devices to the audience: “You’re familiar with digitalizing books and magazines, but now we’re talking about digitizing man, and that’s the future of medicine.” Topol and the other presenters at this week’s mHealth Summit predict that health care in coming years will be highly personalized, ultra-efficient and will most likely involve smart phones and tablets. That is, of course, only if mobile health entrepreneurs can get health care providers to embrace the new technologies, which so far they have been slow to do. During his presentation, Topol clicked through slides of potential apps and devices — some already in existence — that would help patients monitor health conditions remotely. There are contact lenses that can check for glaucoma symptoms, a photo app that can track changes in a suspicious mole and small test strips that can analyze saliva droplets for disease. Health and Human Services Secretary Kathleen Sebelius, another keynote speaker, described a future “where you can take a video of a rash on your foot and get a diagnosis later that afternoon without making a doctor’s appointment....Or get a calorie estimate of how many calories are on your plate by snapping a picture.”
