IHE Patient Demographics Query (PDQ) conformance profiles.
Ships factory functions for the two PDQ transactions in the IHE ITI Technical Framework Vol 2:
- ITI-21 Patient Demographics Query — demographics-only query,
QBP^Q22request →RSP^K22response. Source: IHE ITI TF-2 §3.21. - ITI-22 Patient Demographics and Visit Query — demographics
plus visit information,
QBP^ZV1request →RSP^ZV2response. The response carries aPV1segment per matched patient. Source: IHE ITI TF-2 §3.22.
Both transactions are defined on HL7 v2.5. QPD-1 (Message Query
Name) is pinned to "IHE PDQ Query" for both transactions — the
distinction is the trigger event in MSH-9.
Usage
profile = HL7v2.Profiles.IHE.PDQ.iti_21_query()
HL7v2.validate(msg, profile: profile)Summary
Functions
Returns the complete PDQ profile catalog.
ITI-21 QBP^Q22 — Patient Demographics Query (request).
ITI-21 RSP^K22 — Patient Demographics Query Response.
ITI-22 QBP^ZV1 — Patient Demographics and Visit Query (request).
ITI-22 RSP^ZV2 — Patient Demographics and Visit Query Response.
Functions
@spec all() :: %{required(String.t()) => HL7v2.Profile.t()}
Returns the complete PDQ profile catalog.
@spec iti_21_query() :: HL7v2.Profile.t()
ITI-21 QBP^Q22 — Patient Demographics Query (request).
Requires MSH, QPD, RCP. QPD-1 pinned to "IHE PDQ Query", RCP-1
pinned to "I" (Immediate). QPD-3 carries the search criteria
and must be populated with at least one @PID field reference.
Source: IHE ITI TF-2 §3.21.4.
@spec iti_21_response() :: HL7v2.Profile.t()
ITI-21 RSP^K22 — Patient Demographics Query Response.
Requires MSH, MSA, QAK, QPD. PID, PD1 and QRI segments are part of the optional per-patient group and are validated as present when MSA-1 = AA and QAK-2 = OK.
MSA-1 ∈ {AA, AE, AR}. QAK-2 ∈ {OK, NF, AE}.
Source: IHE ITI TF-2 §3.21.4.2.
@spec iti_22_query() :: HL7v2.Profile.t()
ITI-22 QBP^ZV1 — Patient Demographics and Visit Query (request).
Identical shape to ITI-21 Query except for the trigger event
(ZV1 vs Q22). Supports additional visit-oriented search
fields in QPD-3 (PV1.2, PV1.3, PV1.7, etc.).
QPD-1 is still "IHE PDQ Query" (the message name does not
change between ITI-21 and ITI-22 — the trigger event does).
Source: IHE ITI TF-2 §3.22.4.
@spec iti_22_response() :: HL7v2.Profile.t()
ITI-22 RSP^ZV2 — Patient Demographics and Visit Query Response.
Like ITI-21 response but each matched patient also carries a PV1 segment with PV1-2 (Patient Class) populated.
