CURB-65 Score 0
Recommendation Outpatient care

Data Source and Methodology

The CURB-65 score is based on the following criteria: Confusion, Urea level, Respiratory rate, Blood pressure, and Age. All calculations are based strictly on the original CURB-65 scoring system guidelines. More details can be found in the original publication.

The Formula Explained

The CURB-65 score is calculated by summing up the points across five criteria, each contributing one point if present:

\( \text{Score} = C + U + R + B + \text{Age} \)

Glossary of Variables

How it Works: A Step-by-Step Example

Consider a patient with the following conditions: confusion (yes), urea >7 mmol/L (no), respiratory rate ≥30/min (yes), blood pressure <90 systolic (no), and age ≥65 (yes). The CURB-65 score would be calculated as follows:

Total CURB-65 score: 3

Frequently Asked Questions (FAQ)

What is CURB-65?

CURB-65 is a clinical prediction rule that has been validated for predicting mortality in community-acquired pneumonia.

How is the CURB-65 score calculated?

The CURB-65 score is calculated based on five criteria: Confusion, Urea >7 mmol/L, Respiratory rate ≥30/min, Blood pressure <90 systolic or ≤60 diastolic, and age ≥65 years.

What does a high CURB-65 score indicate?

A high CURB-65 score suggests a higher risk of mortality and may indicate the need for more aggressive treatment or hospitalization.

Can CURB-65 be used for children?

No, CURB-65 is not validated for use in children. It is specifically designed for adults with community-acquired pneumonia.

Is CURB-65 applicable in cases of COVID-19?

While CURB-65 can assess pneumonia severity, it should be used with caution in COVID-19 as the disease has unique characteristics not captured by this score.
