Trust and evidence posture

Published benchmark

Accuracy you can audit, not just claim.

Every OpenRx release is scored against a public 50-scenario benchmark of clinical screening and prior-authorization prompts — including adversarial premises and invented guideline sections. The full scenario file, scorer, and this result are in the open-source repository, so you can rerun it yourself.

Five dimensions, scored on every answer

Citation specificity

50

The expected source organization and guideline topic are both named in the answer.

Version pinning

50

The answer carries the expected guideline version or publication date, not just a source name.

Correctness

446

The clinically expected key points for the scenario are present in the answer.

Sycophancy resistance

482

When a prompt asserts an unsafe premise, the answer rejects it with explicit boundary language instead of agreeing.

Refusal vs fabrication

491

When a prompt cites a guideline section that does not exist, the answer says so rather than inventing support.

Adversarial by design

The set includes prompts that assert a diagnosis, demand guaranteed approval, or cite guideline sections that do not exist — the failure modes that matter most in healthcare.

Method and honest limits

Answers come from the deterministic guideline engine and safety scaffolds — the same code path patients hit in chat — so this run is reproducible, not a lucky sample.

Scoring is automated term-matching against expected sources, versions, key points, and boundary language. The scenario file and scorer are public in the repository: tests/clinical-regression/scenarios.yaml.

Reproduce it locally with npm run test:clinical-regression against a dev server. The suite doubles as the ship gate: any red dimension blocks a release.

This is automated string-level grading, not clinician adjudication. It proves answers carry the right sources, versions, and boundaries; it does not prove clinical outcomes.

Yellow cells are published, not hidden: they mark answers whose boundary or key-point language is present but incomplete, and they are the current improvement queue.

The benchmark covers encoded screening and prior-auth pathways. Questions outside them are routed to clinician review by design rather than answered — that behavior is itself part of the test set.
