Acute physiology and chronic health evaluation — predicts ICU mortality from 12 physiological variables, age, and chronic health status.

Simplified Acute Physiology Score 3 — predicts in-hospital mortality from 20 variables at ICU admission. Validated in 35 countries.

Multiple Organ Dysfunction Score — quantifies organ dysfunction across six systems (respiratory, renal, hepatic, cardiovascular, haematologic, neurologic).

Richmond Agitation-Sedation Scale — 10-point scale from +4 (combative) to −5 (unarousable) for sedation monitoring in the ICU.

Six-level sedation scale — one of the first ICU sedation scoring systems, from anxious/agitated (1) to no response (6).

Confusion Assessment Method for the ICU — most validated delirium detection tool for mechanically ventilated and non-verbal patients.

Nursing Delirium Screening Scale — five-item nurse-administered bedside tool. Score ≥ 2 indicates delirium.

Intensive Care Delirium Screening Checklist — 8-item nurse-rated checklist scored once per shift. Score ≥ 4 indicates delirium; 1–3 indicates subsyndromal delirium.

Glasgow Coma Scale — assesses level of consciousness via eye opening, verbal response, and motor response (3–15).

European System for Cardiac Operative Risk Evaluation II — estimates 30-day operative mortality for adult cardiac surgery.

PaO₂/FiO₂ ratio — standard measure of oxygenation efficiency and basis of the ARDS Berlin Definition severity classification.

Model for End-Stage Liver Disease — the original 2001 laboratory-based prognosis score for liver transplant candidates; superseded for live allocation by MELD 3.0.

Model for End-Stage Liver Disease 3.0 — the OPTN/UNOS liver allocation standard since 2023, adding sodium, albumin, and a sex adjustment to the classic MELD variables.

Neonatal Abstinence Score — assesses opioid withdrawal severity in newborns across 21 signs in CNS, metabolic, and gastrointestinal domains.

National Early Warning Score 2 — standardised 7-parameter tool for early detection of acute illness deterioration. Widely adopted in UK hospitals.

Sequential Organ Failure Assessment — tracks organ dysfunction across 6 systems (respiratory, coagulation, liver, cardiovascular, CNS, renal) on a 0–4 scale. Central to the Sepsis-3 definition.

Simplified Acute Physiology Score II — predicts hospital mortality from 17 variables collected in the first 24 hours of ICU admission.

Quick Sequential Organ Failure Assessment — bedside screening tool for suspected sepsis outside the ICU. Score ≥ 2 indicates increased risk of poor outcome.

Estimates annual ischemic stroke risk in patients with non-valvular atrial fibrillation from eight weighted clinical risk factors, guiding the decision to start oral anticoagulation.
