Is the Future of American Healthcare Digital?

The transformation of U.S. healthcare could revolve around that marvelous little computer in our pockets: the smartphone.

How is U.S. healthcare broken? Let me count the ways:

  • It is too expensive

The dawning of the Age of Digital Care

I could go on and on about the problems in U.S. healthcare, but being a glass-half-full type, I would rather discuss what I believe is hope for a huge transformation in the way healthcare is delivered and consumed. It all revolves around that marvelous little computer that many of us continually engage with throughout the day: your smartphone. Add to that sensors that can pick up physiologic data, sophisticated analytics and artificial intelligence that can transform that data into information that you (and your healthcare providers) can react to, and responsive stuff in our homes, workplaces, schools, cars (the internet of things) that can be programmed to help us live healthier lives and treat illnesses at home. Top it off with new ways to communicate easily and efficiently with healthcare professionals who can provide appropriately timed coaching and advice and you can see how we can create a “healthcare system” that is at once more personalized, more people-centric, and more efficient than our current model of office- and facility-based care.

Can technology help us lose weight?

Let’s take a look at how these technologies could help with one of the most common health problems in America — overweight and obesity. Although most of us have been socialized to believe this is a problem of willpower, it is actually an unintended consequence of the complex biological systems that evolved to help ensure survival when food is scarce. The regulation of food-seeking behaviors is an intricate interplay of neurologic, hormonal, behavioral, biochemical, and genetic factors. This is why we have yet to come up with a magic bullet to help us lose weight and then maintain the weight loss over time. If you mess with one factor, the others kick into high gear to try to maintain the body’s energy stores.

How can technology help? Let’s say you are 15 pounds overweight and have developed pre-diabetes as a result. Your doctor has told you that you should lose weight or you could end up with full-blown diabetes with its attendant increased risk of having a heart attack, stroke, or amputation or developing kidney or eye disease. You’ve tried to lose weight before but after dropping a few pounds, your “willpower” collapses and you eat your way back and beyond your prior weight.

Now, instead of sending you out on your own to figure out how to “Just Lose Weight,” your doctor prescribes an array of digital tools to get you started. Some of the technologies I will describe are already available, some are in development, and some are, well, great ideas waiting for some enterprising digital health entrepreneur to make it real.

The first tool your doctor prescribes is a smartwatch that can continuously collect physiologic data needed to keep you healthy while you are trying to lose weight (e.g., blood pressure, pulse, glucose level, activity level, estimates of calories in and out). The watch is also programmed to help you set reasonable weight loss goals based on your health metrics and personal desires. It is also able to send you messages of encouragement, point-of-eating information (approximately how many calories are in that “healthy” smoothie), and a hot-button to connect you instantly to your health coach and/or designated friends who can provide support at your weakest moments (“Those fries smell great now, but remember the wedding dress you want to fit into.”). The doctor also prescribes an electronic scale and body fat estimator and helps you download an app that lets you take pictures of food you are thinking about consuming and not only tells you how many calories it contains but also how many minutes of your preferred exercise you would have to do to work it off.

After two weeks, your Primary Care nurse receives a message from the digital weight loss program notifying her that your blood pressure is creeping up and your weight loss has stalled. She messages you to tell you that you may require medication to control your blood pressure if you can’t get your weight loss back on track. She will contact you again in a month to see if you have made progress.

Your weight loss coach is also notified that you are not meeting your pre-determined weight loss goals. He sets up a video conference to go over the data and determine what additional tools might be added to your program. During the conference, he discusses a variety of internet-enabled home appliances that can be programmed to help you on your weight loss journey. He notes that some are covered by your health insurance.

Nighttime snacking is identified as a particularly problematic source of excess calories — mostly in the form of full-fat thin mint ice cream. He recommends buying a digital “FridgeLocker” that requires a code to open the freezer after 7 pm. Only your normal weight husband and kids, also thin mint fans, have the code. He also recommends adding increased exercise nudges to your smartphone messaging. A digital check-in two weeks later shows that you are back on track to meet your weight loss goals.

Better, faster, cheaper

All of this is accomplished without office visits and without medications. It is highly personalized and provides automated and human support to help you keep going. It is so inexpensive that insurers have determined it is more cost effective to cover digital tools than to pay for weight loss drugs, bariatric surgery or complications of diabetes.

This is only one example how digitizing healthcare could transform the way we do health. I am sure, my dear readers, that you will think up a jillion other innovations, not just for preventive care, but also for chronic care and urgent care, that are better than the way we do things now. Please leave your ideas in the comment section below so they can inspire someone, somewhere to make them a reality.
