SDC as product infrastructure in Canadian healthcare

Alissa Taylor (Chief Product and Technology Officer) and Gabriel Boilard (Technical Lead, CarePath) from Akinox present two phases of SDC adoption.

Gabriel opens with the existing Linx product, which had grown a custom "dynamic forms" solution: every configuration change required developer involvement, the data was not interoperable, and technical debt piled up. Replacing that layer with FHIR SDC on Aidbox brought self-service form authoring, a complete audit trail out of the box, and extraction into Power BI without new plumbing.

Alissa then walks through CarePath, a new product built on the same foundation to solve a different problem: complex Canadian forms — disability, tax credit, referrals — where the bottleneck is not building the form but assembling the longitudinal evidence needed to fill it. Disability forms have around a 70% first-submission rejection rate, so the real value is in the medical forensics work that goes into each response.

CarePath uses FHIR Questionnaire as the canonical, versionable definition of what needs to be collected, then adds a deterministic hybrid RAG pipeline to retrieve and rank relevant evidence from structured FHIR resources and unstructured documents. The architecture is deliberately human-in-the-loop: CarePath drafts source-linked content for clinician review, attestation is a required workflow step before any response is finalized, and generative methods are used only to make evidence human-readable, never as a source of truth.

Today CarePath exports a pixel-perfect PDF because receiving organizations still expect it; the structured QuestionnaireResponse is the intended canonical record, with the PDF treated as a secondary operational artifact.

Building SDC as product infrastructure? Formbox provides the SDC-native form-authoring layer Akinox rebuilt Linx on — same self-service authoring, audit trail, and structured extraction into Aidbox.
