On Sept. 14 of this year, Apple executives took to the stage to tout the incredible benefits of their new Apple Watch Series 4. While impressively presented in typical Apple fashion, the watch appeared to be only an evolution – not a revolution – in wearable technology. Still, there were a few noteworthy aspects of the new model that seemed to shine a light on the direction of the industry as a whole, and these were all focused on health care.
Like products from FitBit, Garmin, and others, the new Apple Watch can monitor a user’s heart rate and notify if it goes too high or too low. In addition, the watch now includes “fall detection,” and can automatically call for help if its wearer has taken a spill and become unresponsive. Soon it will even be capable of recording a single-lead ECG and detecting atrial fibrillation. While this all sounds fantastic, it also raises an important question in the minds of many physicians (including us): What do we do with all of these new data?
Findings from a Digital Health Study published by the American Medical Association in 20161 reveal that most doctors are aware of growing advances in Mobile Health (mHealth). Interestingly, however, while 85% see potential advantages in mHealth, less than 30% have begun employing it in their practices. This speaks to an adoption divide and highlights the many barriers to overcome before we can bridge it.
First and foremost, providers need confidence in the accuracy of the monitoring equipment, and, thus far, that accuracy has been questionable. Heart rate measurement, for example, is a staple of all currently available fitness wearables, yet is replete with technological pitfalls. This is because most consumer devices rely on optical sensors to measure heart rate. While inexpensive and noninvasive, the accuracy of these sensors can be affected by the interference of sweat, movement, and even the patient’s skin conditions – so much so that FitBit is currently embroiled in a class action lawsuit2 over the issue, in spite of providing disclaimers that a FitBit is “not a medical device.” To improve heart-monitoring capability, Apple has changed to a new sensor technology for this latest generation of Apple Watch. So far its accuracy has yet to be proven, and Apple’s delay in releasing the ECG features until “later this year” suggests there may still be bugs to work out.
Another significant concern raised by the onslaught of wearable health data is how to incorporate it into the electronic health record. Physicians care about efficient data integration, and, when asked in the aforementioned AMA study, physicians named this as their No. 1 functional requirement. EHR vendors have made some strides to allow patients to upload monitoring data directly through an online portal, but the large variety of available consumer devices has made standardizing this process difficult. Doctors have also made it clear that they want it to be straightforward to access and use the information provided by patients, and don’t want it to require special training. These are considerable challenges that will require collaboration between EHR vendors and wearable manufacturers to solve.
The introduction of additional players into the health care space also evokes questions of who owns this new health data set, and who is accountable for its integrity. If history is any indicator, device manufacturers will try their best to eschew any liability, and shift culpability onto patients and physicians. This is causing malpractice insurers to rethink policy coverage and forcing doctors to face a new reality of having “too much information.” While we are excited about the potential for better access to patient monitoring data, we agree that physicians need to understand where their responsibility for these data begins and ends.
Likewise, patients need to understand who has access to their personal health information, and how it’s being used. Privacy concerns will only become more evident as our society becomes ever more connected and as technologies become more invasive. The term “wearable” may soon become antiquated, as more products are coming to market that cross the skin barrier to collect samples directly from the blood or interstitial fluid. Devices such as Abbott’s new FreeStyle Libre continuous blood glucose monitor can be worn for weeks at a time, with its tiny sensor placed just under the skin. It constantly monitors trends in blood sugar and produces enough data points to determine the eating, sleeping, and activity habits of its wearer. This is all uploadable to Abbott’s servers, allowing patients and their providers to review it, thereby further expanding their personal health information footprint.
One encouraging aspect of the expansion mobile health technology is its organic, patient-led adoption. This is quite different from the epoch of electronic health records, which was motivated largely by government financial incentives and resulted in expensive, inefficient software. Patients are expressing a greater desire to take ownership of their health and have a growing interest in personal fitness. Also, the size of the consumer marketplace is forcing vendors to create competitive, high-value, and user-friendly mHealth devices. These products may seem to offer endless possibilities, but patients, vendors, and providers must fully acknowledge existing limitations in order to truly spark a revolution in wearable technology and actually improve patient care.
