The Role of Consumer Grade Techologies

In our quest to deliver health care to patients at the point of need and at the time of need, we should take a careful look at the utility of consumer-grade technologies. Current technologies employed in home telehealth universally have the feel that we are attempting to move the doctor’s office into the home. Can we do better with everyday technologies such as cell phones and consumer-grade measurement devices? I think so. The advantages are that consumers are comfortable with these devices and increasingly reach into their own pockets to pay for them. However, doctors are leery. In a recent survey we did, 64% of physicians believed that home blood pressure monitors could not serve as a substitute for a reading derived in a clinical setting.
So what about accuracy? We know very little about the requirements for accuracy of consumer-grade physiologic sensors. Many companies choose to release products into this market knowing that a direct to consumer sale is less complicated than dealing with the FDA, convincing physicians, etc. Should we be developing a parallel, more expensive, slightly more accurate set of technologies? Or should we compromise, thinking that lower-cost devices have a better chance of being adopted?
Perhaps the more important consideration when considering consumer grade technologies is the opportunity for down-market innovation. So many of the tests we perform on patients are done in the medical setting based on the model that the equipment is too expensive and bulky for home use. Think how this affects the value of tests such as sleep laboratory analysis. What if we could get 85% of the information we can obtain in the sleep lab from a consumer device that was worn to bed in the home environment? One could argue that that be a more valuable source of clinical information, even if the sensor is less accurate.
What is the role of medical validation? What trade-offs should we be willing to make between accuracy and convenience, between collecting data in an unnatural vs. a natural environment.
The market for consumer-grade medical sensors is growing fast and it is incumbent upon the health care industry to leverage this trend to its highest potential.
