Apple Inc has been discussing how its “HealthKit” service will work with health providers at Mount Sinai, the Cleveland Clinic and Johns Hopkins as well as with Allscripts, a competitor to electronic health records provider Epic Systems, people familiar with the discussions said.

While the talks may not amount to anything concrete, they underscore how Apple is intent on making health data, such as blood pressure, pulse and weight, available for consumers and health providers to view in one place.

Currently, this data is being collected by thousands of third-party health care software applications and medical devices, but it isn’t centrally stored. Apple also hopes physicians will use this data to better monitor patients between visits – with the patient’s consent — so the doctors can make better diagnostic and treatment decisions.

Dozens of major health systems that use Epic’s software will soon be able to integrate health and fitness data from HealthKit into Epic’s personal health record, called MyChart, according to a person briefed by Apple. Kaiser Permanente is currently piloting a number of mobile apps that leverage HealthKit, two people have said, and is expected to reach out to Apple to discuss a more formal partnership.

But some implementations with HealthKit may be a challenge due to a web of privacy and regulatory requirements and many decades-old IT systems, said Morgan Reed, executive director of ACT, a Washington-based organization that represents mobile app developers.
