Bye bye IHE XDS and CDA.Publication date: Sep 01, 2021
IHE XDS.b has reached the end of its life cycle - requirements in healthcare have moved beyond the mere exchange of documents, and the underlying technology is getting to be too old. We're no longer offering IHE XDS.b courses. There is a future in hybrid architectures which support document-based exchanges as well as other workflows.
When it comes to interoperability standards training courses act as the proverbial canary in the coalmine: when demand for training in a standard drops, this implies that the number of new projects using that standard is dwindling. If in cunjunction with a drop in interest in training courses one sees a drop in the number of volunteers working on a standard, and a drop in the number of (open source / commercial) tools that support the use and/or development of that standard, then this is a sure sign that usage is in decline.
CDA and CDA training coursesWe've experienced a sharp decline for HL7 version 3 training courses in the past, and demand for CDA courses suddenly plummeted about 7 years ago. Some (national/regional) projects have heavily invested in CDA, and they still produce new CDA implementation guides. That's just a few countries however (e.g. Austria, Saudi Arabia). Others (e.g. the US) still use CDA, whilst working on porting the current CDA capabilities to FHIR documents.
For the reasons above we've decided to no longer offer any CDA training courses. The 'clinical document' principles (a suitable option for some healthcare data exchange scenarios) will be covered as part of our FHIR training course. As already indicated in a blogpost from 2015 the future of (the principles underlying) CDA will be based on FHIR.
IHE XDS and XDS training coursesIHE XDS.b (the second/current iteration of the IHE XDS workflow profile) was created in 2005. Many healthcare organizations were working on their intial architecture to exchange summary information with other organizations, and as such IHE XDS offered a good solution. XDS.b is used all over the world and it will be used for some time to come. The following two key issues have arisen over the past few years:
To use the udnerlying architectural model of XDS (document exchange, based on a registry with document metadata) effectively, XDS will need to be upgraded to
For the reasons above we've decided to no longer offer any IHE XDS.b training courses. The XDS document exchange principles (a suitable option for some healthcare data exchange scenarios) will be covered as part of our FHIR training course. We expect MHD and MHDS gain more traction, and we'll introduce a new training course to cover these profiles as implementation picks up.
