SMART-COP Severe Pneumonia Score (ICU Ventilator & Vasopressor Risk)
Calculate the 0–11 point Australian SMART-COP community-acquired pneumonia score to predict Intensive Respiratory or Vasopressor Support (IRVS) need across Low, Moderate, High, and Very High tiers.
Predict ICU ventilator or vasopressor need—not just 30-day age-driven mortality!
Traditional pneumonia scores like PSI and CURB-65 weight chronological age heavily, which can under-triage physiologically crashing 42-year-olds while over-scoring stable octogenarians. Patrick Charles and the Australian CAP Study (2008) developed the 0–11 point SMART-COP score specifically to identify community-acquired pneumonia patients who require Intensive Respiratory or Vasopressor Support (IRVS)!
SMART-COP awards +2 points each for the three life-threatening major physiologic failures—Systolic BP < 90 mmHg (+2), age-adjusted Oxygenation hypoxia (+2: PaO2 < 70 or SpO2 <= 93% if <= 50 yr; PaO2 < 60 or SpO2 <= 90% if > 50 yr), and Arterial pH < 7.35 (+2)—and +1 point each for Multilobar CXR involvement (+1), Albumin < 3.5 g/dL (+1), age-adjusted Tachypnea (+1: RR >= 25 if <= 50 yr; RR >= 30 if > 50 yr), Tachycardia HR >= 125 bpm (+1), and acute Confusion (+1). Scores >= 5 indicate High IRVS Risk (~1 in 3 patients require ICU ventilator/vasopressors) and >= 7 Very High Risk (~2 in 3)!
| SMART-COP Total Score (0–11) | Predicted IRVS Probability | Clinical ICU / Ward Triage Tier |
|---|---|---|
| 0 to 2 Points | Low Risk (< 4%) | Low IRVS Risk — Routine Ward / Outpatient Pathway |
| 3 to 4 Points | Moderate Risk (~12.5% / 1 in 8) | Moderate IRVS Risk — Monitored Inpatient Bed |
| 5 to 6 Points | High Risk (~33% / 1 in 3) | High IRVS Risk — Early HDU / ICU Consult |
| 7 to 11 Points | Very High Risk (~67% / 2 in 3) | Very High IRVS Risk — Direct ICU Resuscitation |
Age-Adjusted Total SMART-COP Score (0 to 11 Points)
Combines three 2-point major criteria (SBP < 90, age-specific SpO2 cutoff, pH < 7.35) and five 1-point minor criteria.

Maps total SMART-COP points to Low (0–2), Moderate (3–4), High (5–6), or Very High (>= 7) ICU support risk.
