• ICU Limitation: Within the ICU, the full SOFA score is superior to qSOFA for mortality prediction.


• SIRS vs qSOFA: While qSOFA is more specific for mortality, SIRS criteria remain more sensitive for early infection identification.


• Consensus: Introduced in Sepsis-3 (2016) to replace the concept of “Severe Sepsis”.

For professional use only. Clinical judgment should always supersede scores.
