Review and update of IHE The Future & XDS–I Overview - IHE Updates IHE Organisational Changes The Infrastructure Domain Radiology Update XDS-I IHE Political Update IHE has moved on from Radiology Cardiology Laboratory Patient Care Coordination (Vetinary) Moved on from US-centric Established Regional and National Committees Current IHE Domains IT Infrastructure Radiology Cardiology Laboratory Nuclear Medicine Profiles of Interest - ITI Established: Trial: Patient Synchronized Applications (PSA) Patient Identifier Cross-referencing (PIX) Patient Demographics Query (PDQ) Personnel White Pages (PWP) Audit Trail and Node Authentication (ATNA) Enterprise User Authentication (EUA) Retrieve Information for Display (RID) Cross-Enterprise Document Sharing (XDS) Document Digital Signature (DSG) Notification of Document Availability (NAV) Development: Cross-enterprise User Authentication (XUA) New Profiles of Interest Radiology Established: Trial: Reporting Workflow (RWF) Portable Data for Imaging (PDI) Post-Processing Workflow (PWF) Cross-enterprise Document Sharing for Imaging (XDS-I) Teaching File and Clinical Trial Export (TCE) Radiology Audit Trail Option Development: Import Reconciliation Workflow (IRWF) Image Fusion (FUS) Mammography Image (MAMMO) Current Intra-Trust/Cluster Image Sharing Problems DICOM C-MOVE problems Indexing Error correction and cascading Multi-site studies Which trusts hold data for a patient? Updating Network Addressing Issues Unknown Recipients Where is “home” for the study ? Lack of agreement between Vendors on how to go forward How to bolt security onto DICOM The IHE XDS Profile “Generic” means of sharing clinical documents Part of ITI domain (not Radiology) Based on clinical and non-clinical standards: Transmission: Indexing: Documents: http/https ebXML CDA v2 PDF etc. XDS Concepts Actors Document Document Document Document Source Repository Registry Consumer Other concepts “Submission Set” XDS Overview Identity Source Document Registry Document Source Meta-Data Only User Document Repository Full Document XDS-I Like XDS but based on: Uses the same registry A submission set is a DICOM Key Object Note (manifest) object DICOM (data format) WADO or native DICOM (retrieval mechanisms) May include representative sub-sets Use of WADO permits retrieval either as JPEGs for simpler browsers or full DICOM images Compatible with caching but still with integrity XDS-I Overview Identity Source Image Registry Image Source Meta-Data Only User Image Repository Full Images Selected Manifest Problems solved by XDS-I Use of WADO for retrieval solves C-MOVE problems One registry solves indexing problems There is an explicit mechanism to update/delete registrations (no equivalent in DICOM) “Submission Sets” are independent of StudyUID, so mixtures from different trusts are not a problem New but increasingly supported international standard (being implemented in Canada and many others) Uses Standard web security mechanisms Standardised access allows “web access” to be used for pre-fetching etc., and integration with other clinical data Conclusions Virtually all the problems being worked on by CfH have already got agreed international IHE solutions which are supported by vendors XDS & XDS-I in particular provide a mechanism to provide wide-area area, but fully controlled access to medical data, with proper specialisation for images The Connectathon next week should be interesting!
