About this calculator
Overview
The CURB-65 score is a clinical prediction rule used to validate the severity of community-acquired pneumonia (CAP) and determine whether the patient can be managed as an outpatient or requires hospitalization.
💡
Pro Tips
Use 'CRB-65' if urea measurement is not immediately available.
Clinical judgement should always override a score if the patient looks worse than the score suggests.
Monitor oxygen saturation (SpO2) alongside CURB-65 to assess for hypoxia.

Fun Facts
"A score of 0-1 generally indicates a low risk of mortality."
"Scores of 2 should be considered for short hospital stays or supervised outpatient care."
"Scores ≥ 3 often indicate severe pneumonia and require hospital admission, potentially in the ICU."
"CURB-65 is easier to remember than the Pneumonia Severity Index (PSI)."
Formula: 1 point for each criteria: Confusion, Urea level, Respiratory rate, Blood pressure, and Age.
