🧠 SOFA Score – Overview

🧾 Purpose:

To quantify organ dysfunction in critically ill patients (e.g. sepsis) and predict mortality.

📌 Used in:

• ICU admissions

• Sepsis diagnosis (Sepsis = suspected infection + SOFA ↑ by ≥2)

🧪 SOFA Scoring System (0–4 points per organ)

Total score: 0–24

Organ System	Parameter	Criteria
🧠 Neurologic	Glasgow Coma Scale (GCS)	↓ GCS → ↑ score
🫁 Respiratory	PaO₂/FiO₂ ratio	<400 to <100 → Score 0–4
🩸 Coagulation	Platelet count	<150 → ↑ score
🩺 Cardiovascular	Hypotension/Vasopressors	MAP <70 or need for pressors
🧬 Liver	Bilirubin	>1.2 mg/dL → ↑ score
🧪 Renal	Creatinine or urine output	>1.2 mg/dL or ↓ urine output

---

⚠️ Interpretation

• SOFA ↑ by ≥2 = organ dysfunction → consider sepsis

• Higher scores = greater mortality risk
