Schema-Grounded LLM Extraction for FHIR Patient Digital Twins

arXiv CS.CL

ArXi:2601.05847v2 Announce Type: replace We revisit the problem of constructing interoperable patient digital twins from unstructured electronic health records (EHRs) and argue that the task is better cast not as a cascade of extraction modules but as constrained generation of a valid FHIR bundle.
