It appears that a true user centered identity management solution for the healthcare market is on the cusp of reality. In June Microsoft with little fan fair incorporated OpenID into the PHR HealthVault. A health care company and Microsoft recently demonstrated (or at least attempted) their joint collaboration of PHR/EMR interoperability between the electronic medical record and MS Healthvault. Unfortunately the integration was using corporate center identity and thus the user is required to maintain multiple separate accounts for each web service.
Microsoft oddly enough in the PHR game has taken a lead and now if only health care companies would step up we could have the beginnings of not only user oriented identity but a truly portable user profile. Come on health care compaines, stop being legacy oriented and focus on making users the center of identity.
