The Patient Demographics Query (PDQ) Integration Profile lets applications query a central patient information server and retrieve a patient’s demographic and visit information.


Simple enquiry for patient demographic information

  • PDQ provides a very simple means for enquiring to receive demographic information, based on:
  • Partial or complete patient name (printed on the patient record or told by the patient)
  • Patient ID (this may be obtained from printed barcode, a bed-side chart, etc.)
  • Partial ID entry or scan.
  • Date of birth / age range
  • Bed ID


The Patient Demographics Query (PDQ) Integration Profile:

  • allows a Patient Demographics Supplier actor to receive a Patient Demographics Query or Patient Demographics and Visit Query request from the Patient Demographics Consumer actor, and returns demographics (and, where appropriate, visit) information.
  • When the Patient Demographics Supplier Actor is grouped with actors in other IHE profiles that perform patient information reconciliation activities (e.g., Radiology PIR), the PDQ Supplier Actor may use the updated information to respond to PDQ Queries. In addition, the Patient Demographics Query Profile may play an integral workflow role in conjunction with other IHE Profiles.
