Health Level Seven (HL7 www.hl7.org) has released for review and balloting the Personal Health Record System Functional Model DSTU R1 here (zip file).
This is part of an out-of-cycle ballot aimed at rapidly moving the FM into the hands of those who wish to implement. It is a tall drink, with robust provisions for security and interoperability. Those who are accustomed to thinking of a PHR as little more than a fill in the blank web form are going to find a substantially different sort of animal described. In particular, the PHRS described are much more akin to health record banks/trusts (www.healthbanking.org) as described by Amnon Shabo, Marion Ball, Johnathan Gold, Bill Yasnoff and others (including yours truly).
