Patient Information Reconciliation (PIR) coordinates reconciliation of the patient record when images are acquired for unidentified (e.g. trauma), or misidentified patients.


PIR extends Scheduled Workflow to handle:

  • unidentified/emergency patient
  • demographic information updates
    • patient name changes (marriage, etc.)
    • correction of mistakes
    • ID space mergers

Such changes are reliably propogated to all affected systems, which update all affected data. The result is a complete patient record.

In the example of the trauma case, images can be acquired (either without a prior registration or under a generic registration), and read and then later merged with the patients record when their identity is determined.

Patient Information Reconciliation


  • Normal workflow proceeds even when the patient is unknown
  • The patient record reconciles itself into a whole when the patient is identified.
  • Eliminates confusion over which system should reconcile what where.
  • Reduction of errors
    • Reduces incorrectly identified or “lost” studies
  • More complete medical record
    • Supports maintenance of demographics to maintain database correspondence
  • Flexible Trauma Workflow

<Explain a few details about how

  • the PACS is notified of demographics changes
  • the RIS backfills orders
  • the modality doesn't mess with anything


Systems Affected

  • Enterprise-wide information systems that manage patient registration and services ordering (ADT/registration system, HIS)
  • Radiology departmental information systems that manage department scheduling (RIS) and image management/archiving (PACS)
  • Acquisition modalities

  • Vol. 2 - Sections 4.5 to 4.7, 4.11 to 4.13, 4.16, 4.26, 4.27 and Appendix D

Related Profiles

  • Scheduled Workflow provides the data handling framework and is a pre-requisite for PIR
  • Patient Identifier Cross Referencing and Patient Demographics Query can be useful to establish the demographics to reconcile
  • Systems implementing PIR are expected to operate on all relevant objects, including those created as part of Radiology Content Profiles.
  • Workflow profiles in other domains were developed after PIR was written and were able to embed the transactions directly.
