We’ve long talked about the explosion of wearable sensors that’s happening in the market. The number is amazing. Now I’m just waiting for them to go a little deeper as far as what they can offer that’s clinically relevant. That said, I’m also impressed with how small these sensors are becoming. They can easily fit in your pocket or purse with no problem.

An example of this movement is the ECG that was recently sent to me by SnapECG. They have a wide variety of ECG sensors, but they sent me the SnapECG Handheld ECG Recorder (Available on eBay and Amazon). I have to admit that receiving it was a bit underwhelming. It was so simple to use that it didn’t need much information. That said, it would have been nice to have a little card that said basically that there was nothing for me to do other than download the app on my smartphone and get started.

Regardless it was super easy to unpackage it, download the app and pair it with my smartphone. No doubt I’m a more advanced user and so a few more prompts on the mobile app might be a good idea, but all in all, it was amazing how simple it was to start using the sensor. Plus, there’s something calming about watching the ECG being recorded (maybe they should pair it with a mindfulness app).

After doing the reading, the next challenge was figuring out what to do with the data. There’s an option on the app that says “Professional Advice” but it required a login and so I didn’t want to go that direction. Plus, how did I know the quality of the professional advice? As someone active on social media, I decided to share my report on Twitter and ask my community what else I should do with the reading. The amazing part was how simple it was for me to share that report on social media. It made me really wish that sharing the report with my doctor was that easy…but I digress.

Along with some great snarky replies, I also learned about the difference between a single lead ECG and one that would be used in a doctors office. I even had a doctor reply with the following:


The doctor went on to share that it can measure resting heart rate, target exercise heart rate, and rhythm regular/irregular. Although, he did make clear that the key is for the data to come from a wearable that produced accurate data.

I was aware of this possible issue, but I wonder how many consumers wouldn’t think twice about how accurate the readings from the wearable were for them. I can hear someone reasoning that they bought it at BestBuy or Amazon and so they must have vetted the quality of the reading, right? I’m sure some of you are laughing, but I’m quite sure this is how much research many people do on the accuracy of their wearable devices. I instead look for the FDA clearance which SnapECG has said they’re working on and they’re planning to have it cleared in the middle of September.

The SnapECG was originally launched in China and now they’re bringing it to the US. I’ll admit I’m not that familiar with the Chinese medical device world, but the device has been awarded CE certification (EU) and China’s CFDA certification. A lesson that many chinese companies learn is that those don’t really seem to carry much weight to those of us in the US.

In fact, it should come as no surprise that many people in the US will be skeptical of wearables coming from China and other overseas countries. The smartest thing a company like SnapECG can do is to partner with a trusted US brand like the Mayo Clinic or Cleveland Clinic. Most people in the US will trust something that has been vetted by those organizations who are extremely protective of their brands. Plus, it’s easy to see why their “Professional Advice” app feature would carry a lot more weight if that advice was tied to a well known US healthcare organization than a basically anonymous one with Chinese ties.

At the end of the day, the real question for all of these wearables is what value can you provide the patient and how quickly can you provide that value? Plus, will patients understand the value that a single lead ECG can provide them? And will they understand the limitations of what it can and can’t tell you? This is why the software that comes paired with the device is so important. Plus, as these devices become more and more clinically relevant, you’re going to want that data available to a care provider you trust as well.

Yes, I understand some of the challenges of over monitoring and how that can lead to false positives and unnecessary care that has a wide variety of bad consequences. However, over time I believe we’re going to have the right mix of devices, data analytics, and software that will effectively analyze wearable device data and make it actionable and useful to you as a patient and to your doctor. We’re not there yet, but it’s amazing to see how things continue to evolve even since AliveCor offered the first single lead ECG for mobile devices. It still feels like we’re just getting started and none of us can even imagine what we’ll have 10 years from now.

Healthcare Always Has a Why Not – Essential to Focus on the Why To

I recently hosted two roundtables at the Digital Healthcare Transformation conference around the topics of IoT (Internet of Things) and Wearables. The discussion at these roundtables was fascinating and full of promise. Although, it was also clear that all of these healthcare organizations were trying to figure out what was the right strategy when it came to IoT and wearables in their hospitals and health systems. In fact, one of the big takeaways from the roundtables was that the best strategy right now was to have a strategy of experimentation and learning.

While good advice, I was also struck by a simple concept that I’ve seen over and over in healthcare:

If you want a reason not to do something in healthcare, you’ll find one.

It’s a sad, but true principle. Healthcare is so complex that if you want to make an excuse find a reason not to do something, then you can easily find it. In fact, you can usually find multiple reasons.

The most egregious example of this is HIPAA. HIPAA has been an excuse not to do more things in healthcare than any other excuse in the book. When someone says that “HIPAA won’t allow us to do this” then we should just start translating that to mean “I don’t want to do this and so I’m pulling my HIPAA card.” HIPAA certainly requires certain actions, but I know of almost anything that can’t be done in healthcare that could still satisfy HIPAA requirements. At a minimum, you can always ask the patient to consent to essentially wave HIPAA and if the patient consents then you’re not in violation of HIPAA. However, in most cases you can meet HIPAA security and compliance requirements without having to go that far. However, if you’re looking for a reason not to do something, just say HIPAA.

Another one I’ve seen used and is much harder is when someone says, “I think this risks the quality of care we provide.” Notice the emphasis on the word THINK. Healthcare providers don’t have to have any evidence that a new technology, workflow, process, etc actually risks the quality of care. They just have to think that it could reduce the quality of care and it will slow everything down and often hijack the entire project. Forget any sort of formal studies or proof that the changes are better. If the providers’ gut tells them that it could risk the quality of care, it takes a real leader to push beyond that complaint and to force the provider to spend the time necessary to translate why their gut tells them it will be worse.

If we focus on the Why Not in healthcare, we’ll always find it. That’s why healthcare must focus on the Why to!

Use the examples of IoT or wearables and think about all the reasons healthcare should use these new technologies. It’s amazing how this new frame of reference changes your perspective. Wearables can help you understand the patient beyond the short time they spend in the hospital or doctor’s office. Wearables can help you better diagnose a patient. Wearables can help you better understand a chronic patient’s habits. etc etc etc. You obviously have to go much deeper into specific benefits, but you get the idea.

What I’ve found is that once you figure out the “Why to” make a change or implement a new technology, then it’s much easier to work through all of the “Why nots.” In fact, it turns the Why Nots into problems that need to be solved rather than excuses to not even consider a change. You can solve problems. Excuses are often impossible to overcome.

I’d love to hear your experience with this idea. Have you seen Why Nots hijack your projects? What are some of the other Why Not reasons you’ve seen? Has the move to asking “Why to” helped you in your projects?
