How this service works
CURB-65 pneumonia severity from age and discrete clinical flags. Deterministic published score with citation; not a treatment recommendation.
Output
Returns a numeric CURB-65 score (0–5) computed from the five input criteria (confusion, urea >7 mmol/L, respiratory rate ≥30, low blood pressure, age ≥65), along with a severity classification and a citation to the published scoring system. The result is deterministic and does not constitute a treatment recommendation.
Example use cases
Emergency department pneumonia triage
“My patient in the ED is 68 years old, has new-onset confusion, urea is elevated above 7, respiratory rate is 34, and blood pressure is 85/55 — what's their CURB-65 score?”
Inpatient admission decision support
“I need a CURB-65 score for a 55-year-old with no confusion, urea is normal, respiratory rate is 28, and blood pressure is fine — should they be admitted based on severity?”
Outpatient pneumonia risk assessment
“Can you score CURB-65 for a 45-year-old outpatient with community-acquired pneumonia who has no confusion, normal urea, respiratory rate of 20, and normal blood pressure? I want to know if low-risk outpatient treatment is appropriate.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/curb65When to prefer
Use this endpoint when you need a fast, deterministic, evidence-based CURB-65 pneumonia severity score from pre-evaluated clinical flags. Ideal when the calling system has already determined whether urea exceeds 7 mmol/L and other cutoffs, since this endpoint accepts discrete boolean flags rather than raw lab values. Prefer this over manual calculation to ensure consistent citation-backed scoring in clinical decision support pipelines.
Side effects
- Missing required query parameters (age, confusion, urea_high, respiratory_rate_ge_30, low_blood_pressure) returns a validation error
- Age outside valid range 18–120 may return an error or unexpected result
- Boolean flags passed as strings instead of booleans may cause parsing errors
- Network or payment authorization failure returns a 402 or connectivity error
