SOFA based Scoring Systems Respiratory Cardiovascular Neurological Hepatic Renal Coagulation
Original SOFA Score - PaO2/FiO2 ratio
- Respiratory support considered for values 3 and 4
- MAP<70 mm Hg
- Use of vasopressors & dobutamine
- Glasgow coma scale - Bilirubin (mg/dl or umol/L) - Creatinine (mg/dl or umol/L)
- Urinary output
- Platelets (x 1000/mm3)
Modified SOFA (mSOFA) - Respiratory support not included - Blood pressure not included
- Number of vasopressors
-- - Bilirubin (mg/dl) - Creatinine (mg/dl) Same as original SOFA
Modified SOFA (MSOFA) - SpO2/FiO2 ratio
- Respiratory support considered for values 3 and 4
Same as original SOFA Same as original SOFA - Scleral icterus
- Presence of jaundice
Same as original SOFA --
Modified cardiovascular SOFA (mCV-SOFA) Same as original SOFA - Lactate levels
- Shock index
- Number of vasopressors
Same as original SOFA Same as original SOFA Same as original SOFA Same as original SOFA
Extra-renal SOFA Same as original SOFA Same as original SOFA Same as original SOA Same as original SOFA -- Same as original SOFA
Chronic Liver Failure (CLIF-SOFA) - PaO2/FiO2 ratio
- SpO2/FiO2 ratio
- Respiratory support not included
- Use of vasopressors - Presence of grade II or IV hepatic encephalopathy - Bilirubin (mg/dl) - Creatinine (mg/dl)
- Renal replacement therapy
- Platelets (x 1000/mm3)
- International normalized ratio
Mexican SOFA (Mex SOFA) - SpO2/FiO2 ratio
- Respiratory support considered for values 3 and 4
