CURB-65
Background
CURB-65 was an international pneumonia stratification scoring tool derived in the UK, New Zealand, and the Netherlands retrospectively with 1068 patients.[1] Other studies have confirmed mortality increase with increasing scoring. The score does not take into account patient's comorbidities that may also influence disposition location.[2][3]
CURB-65 score | Morality Risk | Recommendation per Derivation Study |
0 | 0.60% | Low risk; consider outpatient treatment |
1 | 2.70% | Low risk; consider outpatient treatment |
2 | 6.80% | Short inpatient hospitalization or inpatient observation |
3 | 14.00% | Severe pneumonia; hospitalize and consider ICU |
4 or 5 | 27.80% | Severe pneumonia; hospitalize and strongly consider ICU |
Scoring
- Confusion
- BUN > 19 mg/dl
- Respiratory rate > 30
- Systolic blood pressure < 90 mmHg or diastolic blood pressure < 60 mmHg
- Age > 65
- Approximate 30-day mortalities and treatment considerations
- +1 → 3%, outpatient treatment
- +2 →7%, inpatient, possible outpatient
- +3 → 14% inpatient, possible ICU
- +4-5 → 30% ICU
