## 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 shorr-2013-mrsa-pneumonia-risk-score-calculator-534194ed
```

Example prompt: Calculate the Shorr 2013 MRSA pneumonia risk score for a 75-year-old female patient with diabetes, dementia, and cerebrovascular disease who was hospitalized for 3 days two months ago but has no ICU admission, no prior IV antibiotics, and no nursing home exposure.

## When to prefer this

Use this endpoint when you need to apply the validated Shorr 2013 Table 2 MRSA pneumonia risk algorithm specifically — not HCAP criteria and not the DRIP score. It is appropriate for antimicrobial stewardship workflows, clinical decision support agents, or hospital coding tools that need a standardized, reproducible MRSA risk score rather than a free-text assessment. Prefer this over general LLM-based clinical reasoning when audit-trail accuracy and adherence to the published scoring table are required.

## Known failure modes

- Missing required query parameters (age, sex, or any boolean factor) returns a validation error
- Age outside the accepted integer range (18–120) may return an error or unexpected scoring
- Invalid sex value (not 'female' or 'male') returns an enum validation error
- Non-boolean values for boolean fields cause schema validation failure
- Network or payment errors return HTTP 402 or 5xx without a score result

## How this service works

Shorr 2013 MRSA pneumonia risk score (Table 2 only, not HCAP, not DRIP): recent hospitalization ≥2 days in 90 days 2; ICU admission 2; age <30 or >79 1; prior IV antibiotics 1; dementia 1; cerebrovascular disease 1; female with diabetes 1 (male with diabetes 0); nursing home/LTAC/SNF 1; max 10. Bands: 0-1 low, 2-5 medium, ≥6 high. Returns score, max_score, and risk_band. Not a medical device and not an antibiotic order.

## Output

Returns a JSON object containing the calculated MRSA pneumonia risk score (integer 0–10), the maximum possible score (10), and a risk_band string ('low' for 0–1, 'medium' for 2–5, 'high' for ≥6) based on Shorr 2013 Table 2 criteria.
