A managed care company has agreed to participate in a software giant’s patient health record program.

Kaiser Permanente, Oakland, Calif., will join a pilot program that will involve transferring data from the Kaiser My Health Manager PHR system to and from the HealthVault program developed by Microsoft Corp., Redmond, Wash.

The Kaiser PHR system now has about 2 million users.

Connecting the systems will give patients the ability to combine detailed Kaiser personal health information along with the health and wellness applications and devices available through the Microsoft system, Kaiser says.

Kaiser notes that the My Health Manager PHR system includes lab test results and also includes clinical data entered directly by physicians, not simply billing data and date entered by patients.

Kaiser will be opening the Microsoft system connection pilot program to Kaiser’s 156,000 employees.

Eventually, Kaiser hopes to make the program available to all of its members, the company says.
