Now the NY Times reports Apple and others using smart phones for clinical data and trials. They note:
People
often learn about new research studies through in-person conversations
with their doctors. But not only did this study, run by Stanford
University, use a smartphone to recruit consumers, it was financed by
Apple. And it involved using an app on the Apple Watch to try to
identify irregular heart rhythms. Intrigued, Mr. ..., who already owned an Apple Watch, registered for the heart study right away. Then he took to Twitter to encourage others to do likewise — suggesting that it was part of a breakthrough in health care. “It’s
not inconceivable, by the time I graduate from medical school,” Mr. ... said, “that the entire practice of medicine can be revolutionized
by technology.”
Unfortunately using this approach can introduce massive biases in any clinical data. Clinical trials have evolved to test hypotheses and must be highly regulated. The FDA does extensive audits to ensure compliance and accuracy, and just casual consumer testing is rant with risks of distorted data. There are no standards for procedures for such trials and no acceptance of the results.
There is potential....but. Take an EKG, or ECG if you will. I admit my age. To determine a cardiac problem one needs all twelve leads taken under controlled conditions. A single lead may tell you something but hardly enough. In fact biases from a single lead could bias a whole study.
Medical data is not like other data. It is patient dependent and patient history dependent. We still need a trustworthy, secure, capable patient centered health record.
