Reference Handler

Maintain Data Integrity​

The Reference Handler in the Centaur® Data Platform ensures the accurate management of relationships between FHIR® resources by resolving internal and external references among the resources. This is a critical function to maintain the integrity of the data, especially when working with complex, interconnected datasets, where one resource may depend on information from another (e.g., linking a Patient resource to an Encounter or Practitioner resource).

Core Functions:​

  • Reference Resolution: The Reference Handler facilitates the resolution of FHIR® resource references, ensuring that relationships between resources are correctly maintained. This includes verifying that each reference points to a valid resource within the system.
  • Identifier Mapping: The handler uses the platform’s identifier mapping system to resolve references accurately. It searches for the appropriate resource identifiers (e.g., Patient IDs, Practitioner IDs) in the FHIR® server and updates the references accordingly.
  • Dynamic Data Adaptation: The Reference Handler adapts to dynamic data environments by automatically adjusting references based on updated or newly created resources. This ensures that references remain valid even as the data is modified.

Cross-Referencing Data​

  • Reference Check: As FHIR® resources are ingested and processed, the Reference Handler scans each resource for internal and external references.
  • Identifier Validation: It cross-references the configuration files, ensuring that the appropriate identifiers are in place to resolve references accurately.
  • Reference Updating: If a reference is found to be unresolved or outdated, the handler updates it with the correct FHIR® ID from the server, ensuring the resource is correctly linked.

Benefits of the Reference Handler:​

  • Improved Data Integrity: By ensuring that all resource references are valid and correctly linked, the Reference Handler enhances the overall consistency and integrity of healthcare data.
  • Streamlined Data Management: The automatic resolution of references reduces manual intervention, saving time and minimizing the risk of human errors in maintaining resource relationships.
  • Support for Complex Relationships: The handler can manage even the most complex relationships between resources, making it suitable for large datasets and complex healthcare environments.
