Google health is to be discountinued. There have been lots of blog discussions about whether or not PHRs have a future.
My opinion is that we'll see more usage of "Patient Portals" by healthcare organisations (as opposed to PHRs where patients add to the record).
For many long-term conditions, we see something similar to the PHR concept from sites like Patient's Like Me, where users can record their information but it might not be integrated with their hospital records.
In the long term, I think that many of the ideas in the PHR concept will probably get incorporated into patient portals, but in the short term it will be more about booking appointments and viewing test results (and not adding anything to the record).
What do you think?
