Overview
CURB-65 is a clinical prediction rule that has been validated for predicting mortality in community-acquired pneumonia[1] and infection of any site[2]. The CURB-65 is based on the earlier CURB score[3] and is recommended by the British Thoracic Society for the assessment of severity of pneumonia.[4]
CURB 65
The score is an acronym for each of the risk factors measured. Each risk factor scores one point, for a maximum score of 5:
- Confusion (defined as an AMT of 8 or less)
- Urea greater than 7 mmol/l (Blood Urea Nitrogen > 20)
- Respiratory rate of 30 breaths per minute or greater
- Blood pressure less than 90 systolic or diastolic blood pressure 60 or less
- Age 65 or older
Predicting Death from Pneumonia
The risk of death increases as the score increases.
| CURB-65 Score | Risk of death |
|---|---|
| 0 | 0.7% |
| 1 | 3.2% |
| 2 | 13.0% |
| 3 | 17.0% |
| 4 | 41.5% |
| 5 | 57.0% |
The CURB-65 has been compared to the pneumonia severity index in predicting mortality from pneumonia.[5]
Predicting Death from Any Infection
A cohort study of patients with any type of infection (half of the patients had pneumonia), the risk of death increases as the score increases[2]:
- 0 to 1 <5% mortality
- 2 to 3 < 10% mortality
- 4 to 5 15-30% mortality
