II. Indications

  1. Sepsis diagnosis and severity evaluation in adults
    1. Recommended to replace SIRS Criteria in 2016 Sepsis-3 Guidelines
  2. Sepsis prognosis

III. Precautions

  1. SOFA Score should not be used to drive or assess specific Sepsis management

    4. Score 3: Dopamine >5 OR Norepinephrine <=0.1 OR Phenylephrine <=0.8
    5. Score 4: Dopamine >15 OR Norepinephrine >0.1 OR Phenylephrine >0.8 OR any Vasopressin
  3. Hepatic Function (using serum Total Bilirubin)
    1. Score 0: Serum Bilirubin <1.2 mg/dl
    2. Score 1: Serum Bilirubin 1.2 to 1.9 mg/dl
    3. Score 2: Serum Bilirubin 2.0 to 5.9 mg/dl
    4. Score 3: Serum Bilirubin 6.0 to 11.9 mg/dl
    5. Score 4: Serum Bilirubin >12 mg/dl
  4. Renal Function (using Serum Creatinine)
    1. Score 0: Serum Creatinine <1.2 mg/dl
    2. Score 1: Serum Creatinine 1.2 to 1.9 mg/dl
    3. Score 2: Serum Creatinine 2.0 to 3.4 mg/dl
    4. Score 3: Serum Creatinine 3.5 to 4.9 mg/dl
    5. Score 4: Serum Creatinine >5.0 mg/dl
  5. Coagulation Function (using Platelet Count)

    4. Score 3: Platelet Count < 50 x10^3/mm3
    5. Score 4: Platelet Count < 20 x10^3/mm3
  6. Neurologic Function (using Glascow Coma Scale)
    1. Score 0: Glascow Coma Scale (GCS) 15
    2. Score 1: Glascow Coma Scale (GCS) 13 to 14
    3. Score 2: Glascow Coma Scale (GCS) 10 to 12
    4. Score 3: Glascow Coma Scale (GCS) 6 to 9
    5. Score 4: Glascow Coma Scale (GCS) <6

V. Interpretation: Total SOFA Score 0 to 24

  1. Sepsis criteria (in addition to current infection)
    1. SOFA Score >=2 (or change in SOFA Score by 2 or more points)
  2. Mortality (based on maximal SOFA Score)
    1. Mortality <10%: SOFA Score 0 to 6
    2. Mortality 15-20%: SOFA Score 7 to 9
    3. Mortality 40-50%: SOFA Score 10 to 12
    4. Mortality 50-60%: SOFA Score 13 to 14
    5. Mortality >80%: SOFA Score 15
    6. Mortality >90%: SOFA Score 15 to 24
