The presentation by Brian Postlethwaite from Microsoft Research provides an in-depth overview of FHIR SDC Extract—the process and tooling for extracting structured FHIR resources from completed SDC questionnaires. It explains the $extract operation, which transforms QuestionnaireResponses into FHIR resource bundles using several approaches: observation-based, definition-based, template-based (new and more flexible), and StructureMap-based extraction. The talk covers technical details such as mapping, context handling, and the use of FHIRPath expressions and extensions to control extraction logic. Real-world examples and tool recommendations (like FhirPath-Lab) illustrate how extraction supports interoperability and advanced healthcare workflows, with emphasis on recent updates in the SDC R4 specification.
A walkthrough of the template based extraction process, along with a comparison of how it differs from the other approaches available. Focusing on practical examples and hands on demonstrations you can follow along at home in the fhirpath-lab's form tester.
With years of experience in diverse environments, Brian has gained extensive knowledge on how software effectively meets user and business needs, which often clash. He has contributed to various software styles, from aged care health environments to fast-paced transactional products, and in time-sensitive newspaper publishing, where multiple users concurrently edit the same story and need real-time updates on changes.
