Conformance #726

> Rationale for Correction: > > When patients have multiple identifiers, particular in the context of cross-enterprise use cases it is desirable to consistently communicate > these in persistent objects as well as in query models. > > The original standard failed to specify a means of identifying the issue of either the Patient ID or the Other Patient IDs values, and > over time Issuer of Patient ID and Other Patient IDs Sequence were added, as well as Issuer of Patient ID Qualifiers Sequence to > the persistent objects and the work flow query models. > > These became available for use in the Query models as a consequence of the existing optional inclusion of "All other Attributes at > Patient Level" in the models, but it seems that some implementers and users remain unclear about the availability of this capability. > The IHE Multiple Image Manager/Archive (MIMA) profile emphasizes the importance of the use of these attributes that explicitly > specify the issuer, and forbid the use of those that don't (Other Patient IDs). > > Accordingly, it is proposed that the PS3.4 Annex C query models be updated to explicitly list the relevant attributes as optional query > keys rather than relying on the "all other" mechanism, and that attributes now no longer appropriate be removed from the query > model and retired. Further, the retrieve behavior is clarified to emphasize that the Patient ID is cannot be qualified by the Issuer of > Patient ID, and so a STUDY rather than PATIENT level retrieval should be used in such cases. > > The same approach is then propagated across all other potential uses of patient identification in other PS3.4 services. > > Attributes that should no longer be used are retired, including Other Patient IDs and Medical Record Locator. > > This CP does not change the standard behavior or implementation; it is only a clarification of the documentation of existing requirements. Current status of this CP is "LB" (Letter Ballot).
