CURB-65 Score


Lim and colleagues have designed a score called CURB-65 to rate mortality in community acquired pneumonia (CAP) - based on information available at initial hospital assessment. Give one point each for following values

C = Confusion
U = Urea (BUN) if more than 20 mg/dl (7 mmol/l)
R = Respiratory rate if more than / = 30/min,
B = BP if SBP less than 90 or DBP less than/= 60,
65 = If age more than / = 65 years

With score 0 expected mortality is 0.7%,
With score 1 expected mortality is 3.2%,
With score 2 expected mortality is 13%,
With score 3 expected mortality is 17%,
With score 4 expected mortality is 41.5% and
With score 5 expected mortality is 57%
