HealthKit aims to bring patients and medical professionals together with great technology and careful consideration for privacy.

That's the challenge faced by Apple, hospitals, and customers alike, who want to take advantage of everything connected devices make possible, but in a way that's responsible, practical, and secure. HealthKit, which syncs data between the Health app on the iPhone, the Apple Watch, over 900 apps, and a broad range of medical and fitness peripherals, with doctors and researchers, aims to accomplish all of that and more. Cedars-Sinai Medical Center in Los Angeles, one of the leading healthcare facilities in the U.S., has just begun the largest HealthKit integration yet. Bloomberg:

The hospital updated its online medical records system this weekend, turning on access to HealthKit for more than 80,000 patients, Darren Dworkin, chief information officer at Cedars-Sinai, said in an interview.

"This is just another set of data that we're confident our physicians will take into account as they make clinical and medical judgments," Dworkin said. "We don't really, fully know and understand how patients will want to use this and we're going to basically stand ready to learn by what will happen."

Previously a lot of this information either sat in silos and couldn't be used together, was subject to manual reporting errors, or simply wasn't recorded at all. It remains to be seen how successful HealthKit will be at solving this problem, but the only way to find out is with institutions like Cedars-Sanai leading the way.
