CURB-65

CURB-65, also known as the CURB criteria, predicting mortality in community acquired pneumonia and infection of any site.

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 m mol /l (Blood Urea Nitrogen > 19)
• Respiratory rate of 30 breaths per minute or greater
• Blood pressure less than 90 mmHg systolic or diastolic blood pressure 60 mmHg or less
• age 65 or older

For Pneumonia

The risk of death increases as the score increases:

• 0—0.7%
• 1—3.2%
• 2—13.0%
• 3—17.0%
• 4—41.5%
• 5—57.0%

0-1 -> treat as an outpatient

2 -> consider a short stay in hospital or watch very closely as an outpatient

3-5 -> requires hospitalization with consideration as to whether they need to be in the ICU

For any infection

The risk of death increases as the score increases:

• 0 to 1 : <5%
• 2 to 3 : < 10% mortality
• 4 to 5 : 15-30% mortality
