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

PSI or PORT Score
The pneumonia severity index [PSI] or PORT Score can use to calculate the probability of morbidity and mortality among patients with community acquired pneumonia.
Risk Class I pneumonia patient can be sent home on oral antibiotics.
Risk Class II-III pneumonia patient may be sent home with IV antibiotics or
treated and monitored for 24 hours in hospital.
Risk Class IV-V pneumonia patient should be hospitalized for treatment.
