## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability geneva-vte-prophylaxis-score-chopard-2006-e26c2567
```

Example prompt: Can you calculate the Geneva VTE prophylaxis score for a 68-year-old patient admitted with cardiac failure and an acute infectious disease, who has a history of VTE, is currently immobilized for more than 3 days, and is obese with BMI over 30, with no stroke, no malignancy, no pregnancy, no hormonal therapy, no respiratory failure, no recent MI, no rheumatic disease, no myeloproliferative syndrome, no nephrotic syndrome, no hypercoagulable state, no long travel, no chronic venous insufficiency, and no dehydration?

## When to prefer this

Use this endpoint when you need to apply the specific Chopard 2006 Geneva VTE prophylaxis scoring table for acutely ill medical inpatients, as distinct from the Padua Prediction Score or the Revised Geneva Score (which assesses PE probability, not prophylaxis). Prefer this over generic risk calculators when the clinical context is non-surgical medical inpatient VTE prevention.

## Known failure modes

- Missing required boolean fields (e.g. dehydration, pregnancy) returns a validation error
- Age outside 18–120 range may return an error or unexpected result
- Misclassifying a Revised Geneva PE score question for this VTE prophylaxis score (different tool)
- Network or payment failure returns HTTP 402 or 5xx

## How this service works

Chopard 2006 Geneva score for VTE prophylaxis in acutely ill medical inpatients. Eleven 2-point factors plus eight 1-point factors including age >60. Max 30. Score <3 low; >=3 high (prophylaxis indicated). Not a diagnosis or order. Not Revised Geneva PE. Not Padua.

## Output

Returns the total Geneva VTE prophylaxis score (0–30) and a binary risk classification: score <3 is low risk (prophylaxis typically not indicated); score ≥3 is high risk (prophylaxis indicated). This is a decision-support computation only — it does not constitute a diagnosis or generate clinical orders.
