Integrating the Healthcare Enterprise Stephen G Davies Royal Glamorgan Hospital

What is IHE? It is an initiative promoting and supporting the integration of IT systems in the healthcare enterprise. It is an initiative promoting and supporting the integration of IT systems in the healthcare enterprise. Integration Goal: Improve the efficiency and effectiveness of clinical practice by: Integration Goal: Improve the efficiency and effectiveness of clinical practice by: ● Improved Information Flow ● Advanced Multi-System Functions

Is IHE another term for EPR? It provides a framework for systems integration which will assist the development of the EPR It provides a framework for systems integration which will assist the development of the EPR Currently limited to radiology Currently limited to radiology

What is IHE? Currently we have: Currently we have: DICOM to exchange imaging data DICOM to exchange imaging data HL7 to exchange order and lab results data HL7 to exchange order and lab results data IHE aims to facilitate the integration of data between systems IHE aims to facilitate the integration of data between systems IHE defines the use of subsets of DICOM and HL7 standards – it is not a standard itself IHE defines the use of subsets of DICOM and HL7 standards – it is not a standard itself

How does this help? Improves integration and interoperability Improves integration and interoperability Integration – disparate systems share info. reducing multiple data entry Integration – disparate systems share info. reducing multiple data entry Interoperability – two systems can carry out a task effectively e.g. both systems have two fields for first and second name Interoperability – two systems can carry out a task effectively e.g. both systems have two fields for first and second name Simplifies workflow Simplifies workflow Purchasers and vendors have confidence that systems will work together Purchasers and vendors have confidence that systems will work together
