Propose to change the 1st paragraph to the following: The PHD Patient Profile may or may not include patient identifiable information depending on a particular need. In a typical upload, the PHD will not provide patient information, and the PHG may need to obtain patient information out-of-band through means other the PHD Patient Profile. In Remote Patient Monitoring, use cases range from the necessity to completely protect Patient Health Information (PHI) to that where no protection at all is deemed necessary. This profile supports all such options. One upload option is that a Patient Resource is never generated and no patient information is present on the PHG. Instead, the health care provider gives the PHG the ‘logical id’ of a Patient Resource that may or may not exist on the destination server. The PHG uses this logical id in the Observation.subject element with the assumption that the server will understand the reference when the Observation is received.
