Before / After
Before
Code with no handoffModel can predict the triage level, but there is no proof dangerous cases were blocked.
Nurse has no clean moment to sign off or override — she just gets a number.
Hospital cannot easily review who approved what decision, or when.
Customer gets a model and a README, not an adoption package.
After
Hospital-ready handoffSafety Gate21 contract tests: pediatric floor, chest-pain routing, suicidal ideation forced-review, sepsis SIRS shape, weak-evidence override, p95 latency cap. All 21 must pass — or the deployment is not ready.
Human DecisionHigh-risk cases pause. The AI does not just flag — it stops and waits for a nurse to sign or override before anything is written back to the patient record.
Audit ProofEach decision stamps what the model decided, confidence score, and latency. PHI goes to a restricted archive, metadata to the cloud index. If the archive write fails, the system screams.
Handoff PackageRunbook, deployment plan, smoke-test suite, ownership guide. What the hospital actually needs to keep this running without the engineer on call.
Business Target (90-day)Target, not achieved outcome: reduce triage-to-first-clinician contact by 15 minutes. Keep down-triage rate below 2%. These are the acceptance criteria in the customer contract — not measured results from a live deployment.
