The company Fyrstain
Fyrstain is a medical software interoperability consultancy specializing in the HL7® FHIR® standard.
Noticing a lack of knowledge in France about the standard, Luc Chatty created the company in 2022 in order to accompany companies and health structures in the paradigm shift caused by the arrival of the standard and the covid-19 crisis.
Because FHIR® is a paradigm shift, the strength of our team lies in the dual technical and business orientation of its collaborators, who benefit from medical experience at various levels.
Founder of Fyrstain and one of the first FHIR® certified experts in France, Luc Chatty is a biomedical engineer (Phelma engineering school) and HL7® FHIR® urban planner, recognised for his expertise in the field of healthcare interoperability.
As French ambassador for the Hospitals-on-FHIR community, he helps bring together European healthcare institutions using the FHIR® standard. He also acts as a consultant for HL7 Europe on numerous European projects (Flute, XpanDH, IDEA4RC, the PHOENIX acceleration initiative for oncology, etc.).
As part of the implementation of the European Health Data Space (EHDS), Fyrstain is involved in several projects aimed at promoting and developing interoperability in healthcare: XiA (Xpanding Innovative Alliance), etc.
Fyrstain provides training in FHIR®, advises on and develops scalable FHIR® architectures tailored to the needs and requirements of healthcare establishments, e-health publishers and institutions. Luc has designed an architecture that is intended to be reusable and shared within the hospital community using FHIR®.
Based in Brittany, Luc is a convinced European and a committed player in e-health mutualisation in France and Europe.
