Internet of Things For Healthcare

The Internet of Things (IoT) is full of promises to transform everything from transportation to building maintenance to enterprise security. But no field may have more to gain than the healthcare industry.

Healthcare providers and device makers are all looking to the IoT to revolutionise the gathering of healthcare data and the delivery of care itself.

But while many of those benefits are already becoming reality, others are still on the drawing board. Two very different IoT healthcare stories crossed by desk this month, taken together they provide a surprisingly nuanced picture of healthcare IoT.

Smart bandages still in prototype

First, the development of advanced prototypes of “smart bandages.” Developed by researchers at Tufts University using flexible electronics, these smart bandages not only monitor the conditions of chronic skin wounds, but they also use a microprocessor to analyse that information to electronically deliver the right drugs to promote healing.

By tracking temperature and pH of chronic skin wounds, the 3mm-thick smart bandages are designed to deliver tailored treatments (typically antibiotics) to help ward off persistent infections and even amputations, which too often result from non-healing wounds associated with burns, diabetes, and other medical conditions.

Sameer Sonkusale, Ph.D., professor of electrical and computer engineering at Tufts University’s School of Engineering, a co-author of Smart Bandages for Monitoring and Treatment of Chronic Wounds, said in a statement: “Bandages have changed little since the beginnings of medicine. We are simply applying modern technology to an ancient art in the hopes of improving outcomes for an intractable problem.”

It’s unclear if Tufts’ smart bandages will be Internet connected, but the potential benefits of an IoT connection here seems obvious. Individual users could have their wounds’ progress monitored more easily, with changes in treatment proscribed as needed, whether or not they’ve been seen by a healthcare provider.

Researchers, meanwhile, could gather real-time data on wound healing and the efficacy of various treatments.

But while the smart bandages have been tested in the lab, they have yet to undergo clinical trials, and there’s no telling how long it will take for them to reach actual patients, or how much they will cost.

Not-so-smart speakers give bad medical advice

While the world waits for smart bandages to show up in the local pharmacy, we’re already able to get medical advice from digital assistants and “smart speakers” such as Amazon Alexa, Google Assistant, and Apple’s Siri. Unfortunately, it turns out that advice isn’t always very good.

A recent in-depth article in Quartz warns that Alexa is a terrible doctor.

The problem is that IoT devices are connected to the Internet, and as authors Katherine Ellen Foley and Youyou Zhou point out, “Many of the Internet’s answers to health-related questions tend to be far-reaching or vague.”

And asking a smart speaker like Alexa is even worse: “Although she is wonderfully helpful with basic questions, her knowledge of the complex medical world is limited, and Alexa generally only serves up one answer.”

Worse, the source of that answer can vary widely. If you ask Alexa to search on a health-related question, you’ll likely get an answer from Wikipedia or WebMD. But the authors note that there are also 1,000 health-related skills on Amazon, ranging in quality from “cumbersome at best [to] peddlers of pseudoscience at worst.”

Many carry disclaimers that their information is “for entertainment purposes only,” but that’s unlikely to stop people from relying on them for medical advice.

One doctor interviewed by the Quartz authors said, “The treatment advice offered by the Alexa skills was generally fine, but could be dangerously unsuitable for specific groups of patients,” depending on allergies or pre-existing conditions.

Another was even more dismissive: “These answers all sound like they just extract information from Wikipedia (which contains a lot of incorrect information) using very simple ‘yes’ or ‘no’ algorithms. Based on my judgment, these are all bad responses.”

Healthcare IoT stuck in the waiting room

OK, so relying on your smart speaker for medical advice probably isn’t a good idea. That seems fairly obvious. But that’s basically what the IoT actually offers right now. And those cool smart bandages? Who knows when they’ll be on store shelves.

Unfortunately, that dichotomy could describe the overall state of healthcare IoT: lots of cool stuff in development, but be wary of what’s available now.
