Microsoft launched a free PHR last week, working in cooperation with a wide variety of partners whose role it will be to help populate the record with useful medical data. The move puts Microsoft into competition for mindshare in an increasingly hot industry sector already peopled by technology rivals like Google and the massive employer-backed PHR effort Dossia. However, in lining up clinical partners, Microsoft is arguably ahead of its competitors, who are still largely at the talking stage in their efforts.

Partners in the PHR effort, HealthVault, include the American Heart Association, Johnson & Johnson LifeScan, New York-Presbyterian Hospital, the Mayo Clinic and MedStar Health. Rather than waiting for consumers to enter their own health information, Microsoft is counting on these partners to provide at least some of the content. For example, New York-Presbyterian has agreed to begin populating HealthVault PHRs automatically with basic patient data. Johnson & Johnson LifeScan, for its part, wants to enable its blood glucose monitors to feed readings into HealthVault accounts.
