DevDays is the most important and largest
FHIR-only event in the world

June 6-9, 2022
Cleveland, OH | Hybrid Edition

About HL7® FHIR® DevDays

DevDays is the largest 100% FHIR-only event worldwide. The DevDays mission is to give health IT professionals around the world the opportunity to learn about FHIR, to meet with colleagues and exchange ideas, and apply what they have learned in their day-to-day work. DevDays accelerates the dissemination of FHIR.
The FHIR founders and core team love and attend DevDays, not only to teach but also to learn from implementers on what can be improved in the standard.

DevDays is a non-business event. The focus is on the people who do the actual work, the developers, the architects, the designers. Tutorials cover all aspects of FHIR, across the different health IT domains, like imaging, devices, terminology, machine learning, cloud, and EHRs.

And since we’re with developers: there is a lot of coding going on at DevDays. “Works in PowerPoint” is not good enough at
DevDays. LET’S BUILD! sessions provide guided exercises, and we always reserve a large hackathon room for meeting with the experts for Q&A.

Background FHIR and DevDays

FHIR (Fast Healthcare Interoperability Resources, is an open-source healthcare data integration standard, which is by now mandated or recommended by governments around the world, like in the US, Germany, Finland, and the Netherlands, as the modern, API-based method for data exchange between care providers, payers, and patients.
HL7 ( is the organization behind FHIR and many other well-known standards as HL7 v2 and CDA. Firely ( is a Dutch company deeply involved in the invention and development of the standard. They also develop tools that bring FHIR to life.

In 2020 and 2021, DevDays went virtual and in 2022 we will organize our first hybrid edition. Hope to see you in Cleveland or online!
