# Webb 2022 COVID-19 Hospitalization & Mortality Risk Score (UTRS)

> Webb 2022 COVID-19 Hospitalization & Mortality Risk Score (UTRS) is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).

Calculates the Webb 2022 simplified COVID-19 risk score (UTRS) for predicting 14-day hospitalization and 28-day mortality based on age, sex, and comorbidities.

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 webb-2022-covid-19-hospitalization-mortality-risk-score-utrs-38d2220a
```

Example prompt: Calculate the Webb 2022 COVID risk score for a 67-year-old male who has diabetes, obesity, hypertension, and dyspnea, identifies as a community of color, has no cardiac arrhythmia, no CHF, no CKD, no chronic pulmonary, liver, cerebrovascular, or neurologic disease, and no severe immunocompromise — and tell me if the score is 6 or above.

## When to prefer this

Choose this endpoint when you need a validated, evidence-based COVID-19 severity risk score grounded in the Webb 2022 publication (Table 6/7), specifically for predicting 14-day hospitalization or 28-day mortality. Prefer it over generic risk tools when the clinical context requires the specific age-decade weighting and the community-of-color equity factor from that study.

## Known failure modes

- Missing required comorbidity fields returns a validation error
- Age outside 0-120 range may produce unexpected scoring
- Incorrect sex value (not 'male' or 'female') causes parameter rejection
- community_of_color must be caller-assigned; the API does not infer race or ethnicity
- Truncated or malformed query parameters return HTTP 400

## How this service works

Webb 2022 Table 6 simplified score for 14-day hospitalization and 28-day mortality. Age decade lookup 0-10=0.5 through >100=5.5. Two points: diabetes, severe immunocompromise, obesity (BMI ≥30), caller-assigned community of color. One point: male sex, dyspnea, hypertension, CAD, arrhythmia, CHF, CKD, chronic pulmonary, liver, cerebrovascular, neurologic disease. score_ge_6 at Table 7 Youden ≥6. Not a diagnosis or allocation order.

## Output

Returns a numeric Webb 2022 UTRS score derived from age-decade lookup and weighted comorbidity flags, plus a boolean score_ge_6 indicating whether the patient meets the Youden-optimal ≥6 threshold associated with elevated 14-day hospitalization and 28-day mortality risk. Not a diagnosis or allocation order.
