World Privacy Forum's report "Personal Health Records: Why Many PHRs Threaten Privacy" released yesterday goes into considerable detail as to why PHR's are a privacy nightmare.
They discuss how PHR vendors may not be covered by HIPAA nor patient/provider confidentiality laws (esp subpoenas.)
They particularly note that PHR vendors that also provide email services have a lot of data that can be easily linked together (...and to you.)
I'd really like to see this sort of thing work, but am cautious.
