Clinical inputs
Allowed range: 0–120 years
Under 40 scores 0, 40–59 scores 5, 60–69 scores 9, 70–74 scores 13, 75–79 scores 15, and 80 or older scores 18.
Allowed range: 0–365 days
Under 14 days scores 0, 14–27 days scores 6, and 28 days or more scores 7.
Allowed range: 3–15 points
A score of 3–4 gives 15, 5 gives 10, 6 gives 7, 7–12 gives 2, and 13–15 gives 0. Use the worst value in the hour before or after ICU admission.
Allowed range: 0–40 mg/dL
Under 2 mg/dL scores 0, 2 to under 6 mg/dL scores 4, and 6 mg/dL or higher scores 5.
Allowed range: 77–109.4 °F
A temperature under 35 °C scores 7. A temperature of 35 °C or higher scores 0.
Allowed range: 0–20 mg/dL
Under 1.2 mg/dL scores 0, 1.2 to under 2 mg/dL scores 2, 2 to under 3.5 mg/dL scores 7, and 3.5 mg/dL or higher scores 8.
Allowed range: 0–300 beats/min
Under 120 beats/min scores 0, 120–159 scores 5, and 160 or higher scores 7.
Allowed range: 0–200 ×10⁹/L
A count of 15 ×10⁹/L or higher scores 2. A lower count scores 0.
Allowed range: 6.5–7.8 pH
A pH of 7.25 or lower scores 3. A higher pH scores 0.
Allowed range: 0–1000 ×10⁹/L
Under 20 ×10⁹/L scores 13, 20–49 scores 8, 50–99 scores 5, and 100 or higher scores 0.
Allowed range: 0–300 mm Hg
Under 40 mm Hg scores 11, 40–69 scores 8, 70–119 scores 3, and 120 or higher scores 0.

Moreno RP et al. SAPS 3—From evaluation of the patient to evaluation of the intensive care unit. Part 2: Development of a prognostic model for hospital mortality at ICU admission. Intensive Care Med. DOI: 10.1007/s00134-005-2763-5. PMID: 16132892. Every admission starts at 16. Box I: age <40 = 0, 40–59 = 5, 60–69 = 9, 70–74 = 13, 75–79 = 15, ≥80 = 18. Hospital stay before ICU <14 days = 0, 14–27 = 6, ≥28 = 7. Location: operating room 0, emergency room 5, other ICU (including intermediate care or recovery) 7, ward or other 8. Cancer therapy (chemotherapy, other immunosuppression, radiotherapy, or steroid treatment) 3. Metastatic cancer 11. Haematological cancer 6. NYHA IV heart failure 6. Cirrhosis 8. AIDS 8. Vasoactive drugs before admission 3. These comorbidity points add. Unplanned admission 3. Reasons add: hypovolemic hemorrhagic shock 3 and hypovolemic non-hemorrhagic shock 3 (both = 6); septic shock 5; anaphylactic, mixed, or undefined shock 5; liver failure 6; severe pancreatitis 9; acute abdomen 3 and other digestive reason 3 (both = 6); intracranial mass effect 10; focal deficit 7; coma, stupor, obtundation, agitation, vigilance disturbance, confusion, or delirium 4. Rhythm disturbance is −5 and seizures are −4, but if both are present only −4 is scored. Surgical status: scheduled 0, no surgery 5, emergency 6. Site: transplant (liver, kidney, pancreas, kidney and pancreas, or other) −11; isolated or multiple trauma −8; CABG without valve repair −6; neurosurgery for cerebrovascular accident 5; all other sites 0. Nosocomial infection 4 and lower-respiratory infection 5 add. GCS 3–4 = 15, 5 = 10, 6 = 7, 7–12 = 2, ≥13 = 0. Highest bilirubin <2 mg/dL (<34.2 µmol/L) = 0, ≥2 and <6 = 4, ≥6 (≥102.6 µmol/L) = 5. Highest temperature <35 °C = 7. Highest creatinine <1.2 mg/dL (<106.1 µmol/L) = 0, ≥1.2 and <2 = 2, ≥2 and <3.5 = 7, ≥3.5 (≥309.4 µmol/L) = 8. Highest heart rate <120 = 0, 120–159 = 5, ≥160 = 7. Lowest leukocytes ≥15 ×10⁹/L = 2. Lowest pH ≤7.25 = 3. Lowest platelets <20 = 13, 20–49 = 8, 50–99 = 5, ≥100 = 0. Lowest systolic pressure <40 = 11, 40–69 = 8, 70–119 = 3, ≥120 = 0. Oxygenation: PaO2/FiO2 <100 with ventilation 11, PaO2/FiO2 ≥100 with ventilation 7, PaO2 <60 without ventilation 5, PaO2 ≥60 without ventilation 0. General equation: logit = −32.6659 + ln(SAPS 3 + 20.5958) × 7.3068, and hospital mortality = exp(logit) / (1 + exp(logit)). Physiology uses the worst value in the hour before or after ICU admission.
