Details
Health Samurai participated in HL7 FHIR DevDays Amsterdam in June 2025, presenting multiple technical sessions and demonstrations. Topics covered included building analytics solutions using "SQL on FHIR," which simplifies querying complex FHIR data by converting it into flat, tabular formats, integrating with databases like PostgreSQL. They also addressed challenges in FHIR validation engines over the first year of using FHIR Schema, proposing a developer-friendly approach inspired by JSON Schema for reliable, language-independent validation. Furthermore, they detailed the technical implementation of "FHIR Native Fine-Grained Access Control" using security labels at both resource and element levels. Automation workflows were demonstrated using Aidbox Forms, including AI capabilities for generating structured forms from PDFs and multilingual translation. The highlight was the presentation on "Patients Know Best," the UK's largest FHIR-based Personal Health Record (PHR). This case study showed how enabling patients to access and share their own health information across various healthcare providers improves self-management and reduces pressure on the overall healthcare system.
