Answer

The percentage of mortality at 30 days associated with the various CURB-65 scores increases with higher scores. The drastic increase in mortality between scores of 2 and 3 highlights the likely requirement for ICU admission in patients with a score of 3 or higher, as shown below:

  • Score of 0 – 0.7% mortality

  • Score of 1 – 2.1% mortality

  • Score of 2 – 9.2% mortality

  • Score of 3 – 14.5% mortality

  • Score of 4 – 40% mortality

  • Score of 5 – 57% mortality
