The donor read,
with the work shown.

Upload a DonorNet packet. OrganAlert turns it into a structured record and runs four published risk scores in code. Every finding shows the source line it came from, and a clinician signs the final read.

Abstract

Extraction is AI-assisted. Scoring is not. The four risk scores run in code, so the same packet always produces the same numbers. The final read belongs to a clinician, who signs it before it informs any decision.

It is decision support, not a diagnostic device.

§ Methods

Four steps, one auditable path

§01

Upload the DonorNet packet

Encrypted on arrival; it stays inside the BAA-covered backend.

§02

AI extraction + vision verification

Every field is cross-checked against the source pages before it enters the record.

§03

Deterministic scoring & flags

The four published models run in code. No model output is allowed to produce a score.

§04Human

Reviewed, co-signed report

A named clinician verifies and signs before it informs any decision.

§ Evidence · Four published scores

Established models, computed in code

Every score in a report comes from a published, peer-reviewed donor-lung model. We do not invent a risk number of our own. Open any score below to see the arithmetic for the specimen donor.

LUNDON — Not scored · not validated for DCD donors
When a model is asked to score a donor outside its validated range, the report says so instead of printing a number. Point tables come straight from the cited papers. Thresholds are configured per program and await faculty sign-off.

§ Transparency

Every finding cites its source

Findings appear as a ledger. Each row names the rule that fired, what it found, how serious it is, and where in the packet it came from. If a finding cannot cite its source, it does not go in the report.

§ Security by design

PHI protection in the foundation

This marketing site never touches PHI. Clinical data lives only in the encrypted, BAA-covered backend, and the constraints below shaped how that backend was built.

PHI encryption at rest

Application-layer AES-256-GCM with per-tenant keys. The database never stores plaintext.

Append-only audit

Access and generation events recorded; IP addresses pseudonymized.

Tenant isolation

Per-request org scoping with Postgres row-level security.

Shift-bound sessions

Idle and absolute session limits enforced on every request.

BAA-covered AI path

PHI reaches a model only through AWS Bedrock, under our signed BAA. No third-party AI APIs.
