# Ghanem 2012 Preoperative Mortality Predictor (PMP)

> Ghanem 2012 Preoperative Mortality Predictor (PMP) is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Computes the Ghanem 2012 Table 5 preoperative mortality risk score from up to 14 caller-assigned clinical flags, returning a numeric score (range −1 to 30) with an associated mortality probability band.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 ghanem-2012-preoperative-mortality-predictor-pmp-f8badc3b
```

Example prompt: Calculate the Ghanem 2012 preoperative mortality score for a 78-year-old inpatient who has sepsis, poor functional status requiring total ADL assistance, a pulmonary comorbidity, a bleeding disorder, and is not obese, has no DNR, no disseminated cancer, no cardiac, renal, or liver issues, not on chronic steroids, and no significant weight loss.

## When to prefer this

Use this endpoint when you need to programmatically compute the validated Ghanem 2012 Table 5 preoperative mortality score for a surgical patient and want a reliable, auditable arithmetic result without building the scoring logic yourself. Prefer it over manual calculation when integrating risk scores into clinical decision-support pipelines, EHR summarization agents, or pre-operative checklists where accuracy and reproducibility matter.

## Known failure modes

- Missing required query parameters (age or any boolean flag) returns a 400 error
- Age outside 18–120 range returns a validation error
- Boolean fields passed as non-boolean strings may cause a parse error
- Payment failure or missing x402 header returns a 402 Payment Required response
- Network timeout if the endpoint is temporarily unavailable

## How this service works

Ghanem 2012 Table 5 bedside preoperative mortality predictor. Inpatient 6, sepsis 4, poor functional status (total ADL assistance) 3, disseminated cancer 1, age (≥80 → 2; 70–79 → 1; 65–69 → 0.5; else 0), cardiac 5, pulmonary 3, renal 1, liver 1, chronic steroid 1, >10% weight loss 1, bleeding disorder 1, DNR 1, obesity −1. Range −1 to 30. Figure 3: <1% died in 0–5, 73% in 20–30. Not a go/no-go for surgery.

## Output

Returns the Ghanem 2012 Table 5 total PMP score (integer or half-point, range −1 to 30) along with the associated Figure 3 mortality probability band (e.g., <1% for scores 0–5, up to 73% for scores 20–30). Does not make a go/no-go surgical recommendation.
