41 PDQ Patient Demographics Query This profile provides ways for multiple distributed applications to query a central patient information server for a list of patients, based on user-defined search criteria. Patient demographics data can be entered directly into the application from which the user is querying by picking the appropriate record from a list of possible matches (called here a patient pick list).
150 T23 HITSP Patient Demographics Query Transaction US HITSP: T23: HITSP Patient Demographics Transaction. The Patient Demographics Query Transaction is intended to provide a ‘list patients and their demographics’ query / ‘patient(s) and their demographics identified’ response message pair (QBP^Q22, RSP^K22) for use wherever such needs exist. This Transaction document extracts the Health Level Seven (HL7) version 2.5 Query and Response data mapping. The underlying basis for this extraction can be found in the Integrating the Healthcare Enterprise IT Infrastructure Technical Framework, Patient Demographics Query integration profile.

Description
ITI22-1 Patient Demographics and Visit Query [ITI-22] transaction references the following chapters of the HL7 v2.5 standard: Chapter 2 - control Chapter 3 - Patient Administration Chapter 5 - Query
ITI22-10 Query responses may return patient identifiers from 0, 1 or multiple patient identifier domains.
ITI22-13 If QPD-8 is empty, the Patient Demographics Supplier shall return all Patient IDs known by the Patient Demographics Supplier for each patient that matches the search criteria.
ITI22-14 If QPD-8 is specified and the domains are recognized, the Patient Demographics Supplier shall return the Patient IDs for each patient that matches the search criteria.
ITI22-15 Any domain not recognized by the Patient Demographics Supplier is an error condition.
ITI22-16 In a single-domain environment, QPD-8 may be ignored by the Patient Demographics Supplier.
ITI22-17 The Supplier shall always return the identifier from the Patient ID Domain known by the Patient Demographics Supplier.
ITI22-18 The Patient Demographics Consumer shall be able to support at least one of the following mechanisms for specifying QPD-8: 1. Transmit an empty value and receive all identifiers in all domains known by the Patient Demographics Supplier (one or more domains), or 2. Transmit a single value and receive zero or more identifiers in a single domain, or 3. Transmit multiple values and receive multiple identifiers in those multiple domains.
ITI22-19 The Patient Demographics Supplier Actor shall support the HL7 Continuation Protocol.
ITI22-2 The Patient Demographics and Visit Query transaction is conducted by the HL7 QBP^ZV1^QBP_Q21 message.
ITI22-20 The Patient Demographics Consumer Actor may request that responses to the query be sent, using the HL7 Continuation Protocol, in increments of a specified number of patient records.
ITI22-21 The Supplier shall use Field MSH-3-Sending Application of the RSP^ZV2 message to return the value it received from the Patient Demographics Consumer in Field MSH-5-Receiving Application of the QBP^ZV1 message.
ITI22-22 The Patient Demographics Supplier Actor shall be capable of accepting, searching on, and responding with attributes in the QPD segment as specified in Table 3.22-2
ITI22-23 The Patient Demographics Supplier Actor must be capable of receiving all valid combinations of subcomponents that make up the Assigning Authority component (i.e., all valid combinations of QPD-3.8).
ITI22-24 The Supplier shall return at least all exact matches to the query parameters sent by the Consumer; IHE does not further specify matching requirements.
ITI22-26 The segments of the RSP^ZV2^RSP_ZV2 message listed without enclosing square brackets in Table 3.22-6 are required. Other segments of the message are optional.
ITI22-27 The Patient Demographics Supplier Actor finds (in the patient information source associated with MSH-5-Receiving Application) at least one patient record matching the criteria sent in QPD-3-Demographics Fields. No patient identifier domains are requested in QPD-8-What Domains Returned. AA (application accept) is returned in MSA-1. OK (data found, no errors) is returned in QAK-2. One PID-PV1 segment group (i.e., one PID segment and one PV1 segment, plus any segments associated with them in the message syntax shown in Table 3.22-6) is returned from the patient information source for each patient record found. If the Patient Demographics Supplier Actor returns data for multiple patients, it shall return these data in successive occurrences of the PID-PV1 segment group.
ITI22-29 The Patient Demographics Supplier Actor finds (in the patient information source associated with MSH-5-Receiving Application) at least one patient record matching the criteria sent in QPD-3-Demographics Fields. One or more patient identifier domains are requested in QPD-8-What Domains Returned; the Supplier recognizes all the requested domains. AA (application accept) is returned in MSA-1. OK (data found, no errors) is returned in QAK-2. One PID-PV1 segment group (i.e., one PID and one PV1 segment plus any segments associated with them in the message syntax shown in Table 3.22-6) is returned for each matching patient record found. If the Patient Demographics Supplier Actor returns data for multiple patients, it shall return these data in successive occurrences of the PID segment group. Within each PID segment, field PID-3-Patient Identifier List contains, in successive occurrences delimited by the repetition separator, the identifiers from all the Patient ID Domains requested in QPD-8. In each occurrence of PID-3, component 4 contains the assigning authority value for one Patient ID Domain, and component 1 contains the Patient ID value in that domain. If an identifier does not exist for a domain that was specified on QPD-8, nothing is returned in the list.
ITI22-3 The segments of the QBP^ZV1^QBP_Q21 message listed in table 3.22-1 are required, and their detailed descriptions are provided in the subsections of section 3.22.4.1.2
ITI22-30 The Patient Demographics Supplier Actor does not recognize one or more of the domains in QPD-8-What Domains Returned. AE (application error) is returned in MSA-1 and in QAK-2. For each domain that was not recognized, an ERR segment is returned in which the components of ERR-2-Error Location are valued as described in table page 178.
