SOFA Score
Predicts ICU mortality based on organ dysfunction
- Highest activation tier
- Mandatory
- How it is scored
- Scored in code; a detected disagreeing draft value is flagged for correction
- Care settings
- ICU
When it activates
Scribeable activates a calculator from the encounter. The SOFA Score can activate when the transcript or pasted chart context documents any of these:
- ICU admission
- Sepsis assessment
- Multi-organ dysfunction
- ICU prognostication
A coded diagnosis can also activate it. ICD-10 prefixes carried by the registry: A41, R65.
Note-type scope: it activates on notes whose subject resolves to critical care, emergency medicine, hospital medicine, pulmonology. A note that resolves to another subject does not carry it even when the clinician's specialty matches; a note with no resolvable subject (a generic consultation) falls back to the specialty match.
Inputs the note needs
7 inputs. Each is resolved from the transcript, the pasted chart context and charted labs; an input marked "asks you" is requested as a clarification when it is undocumented.
| Input | Type | Unit / options | Guidance |
|---|---|---|---|
| PaO2/FiO2 ratio | lab | SOFA respiration: <400=1, <300=2, <200=3, <100=4. | |
| Platelet count | lab | ×10⁹/L | SOFA coagulation: <150=1, <100=2, <50=3, <20=4. |
| Total bilirubin | lab | mg/dL | SOFA liver: ≥1.2=1, ≥2=2, ≥6=3, ≥12=4. |
| Mean arterial pressure (mmHg) | vital | mmHg | SOFA cardiovascular: MAP <70=1 (when no vasopressor is set). |
| Vasopressor support category: none | dopamine_low | low_dose | high_dose | medication |
| Vasopressor support (overrides MAP): dopamine ≤5 or any dobutamine=2, dopamine >5 and ≤15 or norepi/epi ≤0.1=3, dopamine >15 or norepi/epi >0.1=4. |
| Glasgow Coma Scale | exam | SOFA CNS: GCS 13–14=1, 10–12=2, 6–9=3, <6=4. | |
| Serum creatinine (mg/dL) | lab | mg/dL | SOFA renal: ≥1.2=1, ≥2=2, ≥3.5=3, ≥5=4. |
Scoring
6 organ systems (respiratory, coagulation, liver, cardiovascular, CNS, renal), each 0-4 points.
Respiratory(PaO2/FiO2 PaO2/FiO2 ratio) + Coag(plt Platelet count) + Liver(bili Total bilirubin) + Cardio(MAP Mean arterial pressure (mmHg), pressors Vasopressor support category: none | dopamine_low | low_dose | high_dose) + CNS(GCS Glasgow Coma Scale) + Renal(Cr Serum creatinine (mg/dL)); each 0–4 points, sum 0–24
Interpretation
Score correlates with mortality. Serial measurements track trajectory. Delta SOFA >=2 with infection = sepsis.

How Scribeable handles it in the note
When an encounter activates the SOFA Score at the mandatory tier, Scribeable resolves its inputs from the transcript, the pasted chart context and any charted labs, and asks you for a missing input you can supply before the note is finalised. Bedside-exam and separately ordered study values are not requested one input at a time; a calculator that carries a combined clarification question may still put that single question to you.
The score is computed in code from the resolved inputs, not recalled by the language model. If the draft states a SOFA Score value that disagrees with the computed one, the disagreement is flagged to the second drafting pass, which is instructed to correct the score and its interpretation before you see the note.
Classified as a risk score: activated strictly, by a documented trigger, never by a permissive reading of the encounter.
