Clinical Overview

The CURB-65 score is a widely validated clinical prediction rule used to estimate mortality in patients with community-acquired pneumonia (CAP). By evaluating Confusion, Urea, Respiratory rate, Blood pressure, and Age (≥65), it effectively guides the clinical decision of whether a patient safely qualifies for outpatient treatment or requires hospitalization/ICU admission.

Clinical Pearl

In the United States, Blood Urea Nitrogen (BUN) is typically measured rather than urea. A BUN > 19 mg/dL is roughly equivalent to a Urea > 7 mmol/L. Do not use CURB-65 for healthcare-associated or ventilator-associated pneumonia.

Pitfalls & Warnings

  • May underestimate the risk in young, otherwise healthy patients with severe respiratory compromise because age and chronic comorbidities do not add points.
  • CRB-65 (omitting urea) can be used in primary care where lab results are delayed, though it is slightly less sensitive.
