Mortality according to CURB-65

[Dr.Sudan]

CURB-65 criteria of severe pneumonia

• • Confusion (abbreviated mental test score < 8/10)
  • Urea > 7 mmol/L
  • Respiratory rate = 30 / min
  • BP: systolic < 90 or diastolic < 60 mmHg
  • age > 65 years

The risk of death at 30 days increases as the score increases:

• 0—0.6%
• 1—3.2%
• 2—13.0%
• 3—17.0%
• 4—41.5%
• 5—57.0%

[Dr.Sudan]

There are numerous predictors of increased severity and risk of death from community acquired pneumonia including white cell count < 4 or > 20, co-morbidity such as renal disease, multi-lobar involvement on CXR and temperature < 35°C or > 40°C
