The five criteria
Confusion, urea elevation, fast breathing, low blood pressure and age of 65 or more each add one point. The rule was derived and validated in large pneumonia cohorts worldwide.
Understanding your result
- Zero or one suits outpatient care for most patients
- Two usually means at least a short admission
- Three or more indicates severe pneumonia needing hospital treatment
Where the score fits
It informs but never replaces clinical judgment. Social factors, oxygen levels, other illnesses and vomiting all matter to the final decision.
A safety note
Anyone with breathing difficulty, chest pain, confusion or bluish lips needs urgent assessment regardless of score.
