Punteggio CURB-65

Evaluate the severity of community-acquired pneumonia and guide decisions on patient management (inpatient vs. outpatient).

Pneumonia varies from a mild illness to a life-threatening condition. The CURB-65 score is a clinical prediction rule used to estimate the mortality risk of community-acquired pneumonia (CAP). By scoring five simple clinical factors, physicians can more objectively decide whether a patient can be safely treated at home, needs a hospital bed, or requires intensive care.

BUN > 19 mg/dLUrea > 7 mmol/L

Low Risk (Group 1)

Mortality risk is low (approx. 1.5%). Consider outpatient treatment.

Come funziona

One point is assigned for each of the five criteria. The total score (0-5) correlates with 30-day mortality risk and guides site-of-care decisions.
