The document sharing infrastructure provided by XD* allow for the publication and use of clinical documents associated with a patient. This profile allows for a Patient Privacy Policy Domain (e.g., an XDS Affinity Domain to have a number of Patient Privacy Policies that can be acknowledged (aka consent). This allows for more flexibility to support some patient concerns, while providing an important and useful dataset to the healthcare provider. Without BPPC, the XDS profile requires that the administrators of an XDS Affinity Domain creates and agrees to a single document publication and use policy (See ITI TF-1: Appendix L). Such a single XDS Affinity Domain Policy is enforced in a distributed way through the inherent access controls of the systems involved in the XDS Affinity Domain.
