Visualizing Healthcare Interoperability: Introducing a Topology Diagram Tool
Healthcare Integration Topology Builder Diagram HL7, FHIR & DICOM networks - Saga IT
Summary
This article introduces a free online tool for creating an 'Integration Topology Diagram,' which maps the data exchange pathways between multiple clinical systems. Users can visualize and document the connection status of various systems, including EHR, PACS, and LIS, based on protocols like HL7 and FHIR.
Details
The featured 'Healthcare Integration Topology Diagram' serves as a map detailing how clinical systems exchange data—which system connects to which, and using what protocol (HL7 v2, FHIR R4, DICOM, SQL, etc.). The diagram is constructed by placing various nodes (EHR/EMR, PACS, LIS, Database) around a central hub (the integration engine), with connection lines labeled with specific protocols and port numbers. A key architectural concept highlighted is the shift from complex 'point-to-point' wiring to the standardized 'hub-and-spoke' model. By routing all data through a central 'integration engine' (e.g., Mirth Connect, OIE), the system standardizes data flow and creates a single reference artifact for interface management or security reviews. The tool supports major healthcare protocols including HL7 v2/MLLP, FHIR R4/REST, and DICOM. Users can export these connection details as PDF or JSON files, making them suitable for inclusion in Statements of Work (SOW) appendices or runbooks. This provides a technical guide on visualizing and standardizing data connectivity within complex healthcare IT environments.
