MedGate: Clinical Action Review Console

The problem

Health AI agents are starting to act, not just answer. They order labs, message patients, renew prescriptions, and update charts. Every one of those actions crosses a line where software stops reading and starts doing. Today there is no consistent human checkpoint in that loop, and audit trails are afterthoughts.

The idea

MedGate is a clinical action review console: an approval queue between an AI agent and consequential clinical actions. Nothing consequential executes until a human looks at it. The reviewer sees the agent's plan beside the untrusted instruction found inside a retrieved referral note, quoted verbatim and labeled as untrusted data, then makes one of three explicit choices: approve as requested, trim and approve, or block.

What the prototype does

• Review queue: pending clinical actions with synthetic MRNs, risk badges, and the reason each was held (off-hours, chart mismatch, untrusted text, controlled-substance ceiling).
• Case detail: the full agent plan, the untrusted note excerpt, and approve / trim & approve / block with a required decision note.
• Audit log: immutable, newest-first record of every decision: who, what, when, verdict.
• Policy settings: plain-language toggles: off-hours messaging hold, chart-mismatch holds ordering, controlled-substance ceiling, untrusted-text escalation, auto-clear routine reads.

Design decisions

• The reviewer sees evidence, not a wall of logs: why an action was held, what the agent planned, and what untrusted data influenced it.
• Untrusted content is always quoted and labeled, so the human review compares claims against provenance rather than vibes.
• Every decision is reversible in the queue but permanent in the audit log.

How we built it

A single-page front end in HTML, CSS, and vanilla JavaScript, hosted on GitHub Pages. All demo data is synthetic.

Challenges

Scope. A real deployment would need EHR integration, identity, and clinician notifications. We cut all of it to make the review surface itself excellent, and we say so plainly: MedGate is a workflow prototype, not a medical device, and it contains no real patient data.
