Follow-up FHIR DevDays 2025
Follow-Up on the FHIR Dev Days
After much anticipation, the DSF team participated at the FHIR DevDays 2025. The event was held from June 3rd until June 6th in Amsterdam. As the worldās largest event dedicated to HL7 FHIR, DevDays brings together health IT professionals from across the globe to deepen their understanding of the standard, to exchange knowledge, and to explore innovative real-world applications in healthcare. The event offered us a valuable opportunity to share our insights and lessons learned from implementing and working with FHIR in various contexts such as the DSF and the International Patient Summary (IPS).
Community Talk: Fostering Research with FHIR and BPMN
On the last day of the conference, Hauke Hund presented lesson learned from the DSF in his talk āFostering Research: Real-World Data Sharing and Process Orchestration with FHIR and BPMNā. In this session, Hauke shared valuable lessons learned from the implementation, rollout, and maintenance of different DSF networks. The talk illustrated how combining FHIR with Business Process Model and Notation (BPMN 2.0) enables secure, automated, scalable sharing of real-world research data across institutional boundaries.

Birds of a Feather Session: FHIR and Terminology Validation
On Thursday, we hosted a spontaneous deep-dive session on FHIR and terminology validation, which proved to be a great success, sparking lively discussions and active engagement among participants. With over 70 registrations and 35 attendees, the session underscored the significance of this topic within the FHIR community.
The session explored how terminology validation can be integrated into current workflows and it shed light on common challenges and limitations of existing FHIR validators. The dicsussion also included ideas for future improvements and their potential for wider adoption of FHIR validation tools.
This session served as a valuable preparation for the upcoming MII validation workshop. If you're interested, you can find more information here in german: FHIR Validation Workshop
Following the event, the DSF Validator was published and is available at: DSF FHIR Validator
Community Talk: International Patient Summary (IPS) Challenge 2025
On Tuesday, we hosted a community talk focused on the International Patient Summary (IPS) Challenge 2025. The IPS is a standardized set of clinical data that provides a concise overview of a patientās current health status. As part of the challenge, students from Heilbronn University and the Universidad de Chile collaborated to implement and demonstrate IPS-based use cases.
Participants in the challenge had the opportunity to present their work at the HL7 Chile Connectathon. The FHIR Implementation Guide (IG) was used as the basis for five demonstrators. The use cases focused on providing medical summaries for patients with conditions such as hypertension, food intolerance, post-surgical history, diabetes, and asthma, with a particular focus on cross-border care scenarios
Maximilian Kurscheidt shared our insights and lessons learned from this initiative. Topics included challenges in cross-border IPS data exchange, effective visualization of longitudinal health records, and the complexities of translating FHIR resources and medical terminologies across languages and systems. The talk also addressed handling medical imaging within the IPS and compared general-purpose IPS viewers with use case-specific applications.

FHIR DevDays 2025 was an excellent opportunity to showcase our work, gain valuable insights, and engage with the global FHIR community. We extend our sincere thanks to the organizers and to everyone who participated in our talks and discussions. We truly appreciated the chance to connect with fellow experts and look forward to continuing the dialogue on interoperability, research, and innovation in digital health innovation.
