Robust standards and specifications require the collaboration and input of all stakeholders, and the EHDS is no exception. Xt-EHR and HL7 Europe have both launched consultations to their communities, on topics that may partly overlap. In this webinar, speakers discussed how HL7 Europe and Xt-EHR are working together on the HL7 FHIR Implementation Guides, how the Xt-EHR logical model have been used as input for this work, and how to respond to the open consultations.
