ISO/HL7 10781 - Electronic Health Record System Functional Model, Release 2.1 - Local Development build (v0.14.0) built by the FHIR (HL7® FHIR® Standard) Build Tools. See the Directory of published versions

Requirements: TI.3 Registry and Directory Services (Function)

Active as of 2024-06-01
Statement N:

Enable the use of registry services and directories to uniquely identify, locate and supply links for retrieval of information related to:

  • patients and providers for healthcare purposes;
  • payers, health plans, sponsors, and employers for administrative and financial purposes;
  • public health agencies for healthcare purposes, and- healthcare resources and devices for resource management purposes.
 Description I:

Registry and directory service functions are critical to successfully managing the security, interoperability, and the consistency of the health record data across an EHR-S. These services enable the linking of relevant information across multiple information sources within, or external to, an EHR-S for use within an application. This applies to directories/registries internal to the EHR-S as well as directories/registries external to the EHR-S. Transmission may occur automatically or manually and may include small or large amounts of data. Directories and registries support communication between EHR Systems and may be organized hierarchically or in a federated fashion. For example, a patient being treated by a primary care physician for a chronic condition may become ill while out of town. The new provider's EHR-S interrogates a local, regional, or national registry to find the patient's previous records. From the primary care record, a remote EHR-S retrieves relevant information in conformance with applicable patient privacy and confidentiality rules.

An example of local registry usage is an EHR-S application sending a query message to the Hospital Information System to retrieve a patient's demographic data.
