Find the right patients
Extract codes from notes, referrals, and historical records, then make inclusion and exclusion criteria queryable on a shared FHIR timeline.

Construct longitudinal datasets from patient charts, including the narratives. Construe extracts standard codes and keeps them traced across years of patient records, so every cohort starts with evidence you can inspect.
The source record
Every code stays traceable to the note it came from, across all five specialties.● Coded, cohort-ready longitudinal record
Five standardized codes, traced across nine years of care, make this patient's history ready for a defined cohort, with the source evidence retained for review.
extracted as standard codes by Construe · written to a FHIR timelineWhy longitudinal data matters
Longitudinal data sets are most useful when the data is labelled and tagged with standard terms, which can be traced across years of patient records.
Build quality datasets
Datasets your users can trust.
Patient cohort identification, genomic-care platforms, and evidence teams all run on the same primitive: codes extracted from narrative, kept on a longitudinal FHIR timeline.
Make every record analysis-ready
Standard terms from narrative and semi-structured sources become longitudinal FHIR data your applications can filter, join, and audit.
Reproduce the dataset
Build fit-for-purpose cohorts from years of care. Source-linked code extraction makes every run reviewable, repeatable, and ready for regulatory-grade evidence workflows.
Why it holds up
Built for reproducible research.
Standard terminology, applied consistently
Construe extracts standard codes from narrative and semi-structured records, retaining the terms and source evidence behind every data point.
Longitudinal by construction
Everything resolves to FHIR on a patient timeline, including codes, labs, medications, and encounters, so data stays connected across years of care.
Reproducible, reviewable datasets
Deterministic extraction makes each cohort build repeatable, while source citations let reviewers trace every coded fact back to its originating record.
