CURB-65 severity score
CURB-65, also known as the CURB criteria, is a clinical prediction rule that has been validated for predicting mortality in community-acquired pneumonia and infection of any site.
Method: Score 1 point for each of the following features that are present:
- Confusion (mental test score ≤8 new disorientation in person, place or time)
- BUN > 20 mg/dL
- Respiratory rate ≥30 breaths/min
- Blood pressure (systolic <90 mm Hg, or diastolic ≤60 mm Hg)
- Age ≥65 years
Interpretation of CURB-65 score:
0-1: Probably suitable for home treatment; low risk of death
2: Consider hospital supervised treatment
≥3: Manage in hospital as severe pneumonia; high risk of death
