Evidence & audit

Not a record. Verifiable proof.

Every GetConsent session produces a cryptographically secured evidence pack. Every event (viewed, answered, comprehension checked, signed) is hash-chained and server-signed. When a consent decision is ever questioned, you do not reconstruct what happened. You recompute it.

Comprehension, not acknowledgement

The record shows what the patient understood

A signature proves a patient held a pen. A comprehension check proves they understood the specific risk. Validated questions are presented section by section, with up to three attempts and full attempt history, so the evidence captures understanding, not just receipt.

Section-by-section
Information is delivered in digestible sections with “I understand” checkpoints, never a wall of text to scroll past.
Validated questions
Each section can carry a comprehension question. The answer, the attempt count, and the outcome are all recorded.
Surfaced for the clinician
Where a patient struggled is visible before the consult, so the conversation targets exactly what they did not understand.
The audit trail

Hash-chained and server-signed

Every event is linked to the one before it: event_hash = SHA-256(prevHash | canonicalJSON(payload)). Change any event and every hash after it breaks. Each entry is also digitally signed by the server, providing non-repudiation. A global anchor chain makes even whole-session deletion detectable.

  • Tamper-evident by construction
  • Server-signed for non-repudiation
  • Independently verifiable hash chain
  • Global anchor detects deletion

The evidence pack

Everything, in one tamper-evident document

Generated automatically on completion, and exportable in the format your lawyers, auditors, or EMR need.

PDF evidence pack
The exact content shown, every response, comprehension results, patient questions and concerns, clinician attestation, dual signatures, and the complete audit chain.
Machine-readable JSON
A self-contained export with the full audit trail, hash-chain verification metadata, and cryptographic signatures, ready for legal discovery or regulatory audit.
FHIR R4 resources
Consent and Provenance resources in standard healthcare-interoperability format, plus DocumentReference for the consent PDF.
EMR summary export
A one-click structured summary, JSON or clinical-note format, for pasting straight into the patient record.
Evidence-grade, by definition
“Evidence-grade” means meeting the standard required for legal proceedings and regulatory audit. When you do consent well, structured content, verified comprehension, documented conversation, the legal evidence is a natural output, not a separate task.

From “we think consent was obtained” to “here is the record: verify it yourself”

Clinics & practices

Send a real consent today

Solo clinicians and small practices set up in an afternoon and send their first consent the same day. No procurement, no sales call, no card. Nothing about your current process has to change until you are satisfied.

Hospitals & networks

See it run on your workflow

Multi-site hospitals and networks get a 30-minute demo configured for your EMR, your SSO, and the governance reports your accreditors actually ask for. You leave with a working trial account.
