Just because the Food and Drug Administration has given the Apple Watch and other wearable devices the OK to market the health benefits of their tracking and algorithms doesn’t mean that the data they generate are useful for either patients or their doctors, a health tech expert said Thursday at the STAT Breakthrough Summit West in San Francisco.
“Yesterday, I saw a patient with type 2 diabetes who has a continuous glucose monitor, and so she’s been tracking her blood sugar every five minutes,” said Ida Sim, a primary care physician and chief research informatics officer at the University of California, San Francisco. “[I] sat with her for almost an hour yesterday. I couldn’t get to her CGM data — she had it on her phone, but the report goes into a website that I didn’t have the login to, and it hadn’t been downloaded into my electronic medical record. So all this tracking data, I didn’t have it.”
Not only do clinicians not have the ability to access data that their patients want to use to guide their care, but primary care doctors often don’t know how to interpret that firehose of data, said Sim. She asked some of her endocrinology research colleagues how they use that data and they explained the calculations needed to create biomarker metrics from them. That made the data largely useless to her as a doctor, and it was frustrating.
