From: Robustness of sepsis-3 criteria in critically ill patients
Old sepsis | |
---|---|
MARS-sepsis | Presence of ≥ 2 SIRS criteria and organ failure within a 4-day window around suspected infectiona, b |
MARS-septic shock | MARS-sepsis and use of vasopressor for hypotension within a 4-day windowa, c |
Sepsis-3 | |
Sepsis-3 (4-day window) | Suspected infection and an acute SOFA score increase of ≥ 2 points within a 4-day window a |
Septic shock-3 | Sepsis-3 and vasopressor-dependent hypotension (i.e., circulatory SOFA score ≥ 2) plus an increased serum lactate level of > 2 mmol/L within a 4-day window a, d |
Assessments of minor variations in diagnostic criteria | |
Reduced observation window | Similar to sepsis-3, but with a 2-day window around suspected infection (i.e., an increase between the day before and the day of the onset of infection) |
Absolute SOFA score | Suspected infection and an absolute SOFA score of ≥ 2 points at the day of onset of infection and within a 4-day windowa |
Septic shock-3 ignoring lactate | Similar to septic shock-3, but without the requirement of increased serum lactate levels if not measured |
