Rules first. Then the reason.

Imedica keeps judgement and explanation apart. People with clinical authority write the rules, software applies them the same way every time, and an AI model explains the result.

Reason. The right ventricle depends on preload. Nitrates drop it, and the pressure with it.

Four stages, two kinds of authority.

  1. Stage 1 of 4

    A physician writes the call

    Each scenario is a sequence of moments: the scene, the patient, the vitals on the monitor. For every moment the physician lists what a paramedic might do and what each choice means: correct, acceptable, suboptimal, harmful, or critical. They add the reason, the directive it comes from, and how long the right action can wait.

    Draft → review by a second physician → published. Every edit is on the audit log.

  2. Stage 2 of 4

    A paramedic runs it

    The scenario opens with dispatch. Vitals change as the patient responds, the clock keeps running, and the action menu holds everything a crew can do on scene, not just the right answers. A harmful choice changes the patient. A critical one ends the call.

    Works in a browser on a phone, tablet or station computer. Ten to fifteen minutes.

  3. Stage 3 of 4

    The rules score it

    Scoring is deterministic. The same decision at the same moment earns the same verdict every time, and the right action taken too late is marked late. Required steps that never happened are listed in the debrief.

    No model decides a score. The grade is reproducible and auditable.

  4. Stage 4 of 4

    The debrief explains it

    Each decision comes back with its triage-coloured verdict and the physician's reason. Claude then writes a short explanation tying the run together: what went well, the decision that mattered most, and what to practise next. It sees the scenario and the decisions, never who made them.

    Physicians can approve or flag any explanation from the review queue.

Five verdicts, coloured like triage tags.

Paramedics already read these colours without thinking, so a debrief can be scanned in seconds.

Correct
The right action at the right time.
Acceptable
Defensible, but not the strongest choice.
Suboptimal
Not indicated here, or the right action given too late.
Harmful
Contraindicated. The patient gets worse.
Critical
Serious harm. The scenario ends.
