SMART-COP


SMART-COP is a clinical tool used to predict the severity and guide the management of community-acquired pneumonia (CAP). It is an acronym that stands for:

  • Systolic blood pressure: ≤ 90 mmHg (2 points)
  • Multilobar chest radiography involvement (1 point)
  • Albumin level: < 35 g/L (1 point)
  • Respiratory rate: ≥ 25 breaths per minute (30 if age ≥ 50) (1 point)
  • Tachycardia: Heart rate ≥ 125 beats per minute (1 point)
  • Confusion: New onset or worsening of confusion (1 point)
  • Oxygenation:
    • PaO2 < 70 mmHg or SaO2 < 93% on room air if age < 50 (2 points)
    • PaO2 < 60 mmHg or SaO2 < 90% on room air if age ≥ 50 (2 points)
  • PH level: < 7.35 (2 points)

Scoring System

Each criterion in the SMART-COP tool is assigned a point value. The total score, ranging from 0 to 11, helps determine the severity of CAP and the need for intensive respiratory or vasopressor support (IRVS). The interpretation of the score is as follows:

  • 0-2 points: Low risk, indicating that the patient is unlikely to need IRVS.
  • 3-4 points: Moderate risk, suggesting some need for IRVS.
  • 5-6 points: High risk, indicating a significant need for IRVS.
  • 7 or more points: Very high risk, with a very high likelihood of needing IRVS.

Application in Clinical Practice

SMART-COP helps healthcare providers make informed decisions about the level of care required for patients with CAP. It assists in identifying those who might need more intensive treatment and closer monitoring, potentially guiding decisions regarding hospital admission, ICU transfer, and the urgency of initiating advanced therapies.

Benefits of SMART-COP

  • Improved Risk Stratification: Allows for a more accurate prediction of CAP severity compared to other tools like CURB-65.
  • Guided Treatment: Helps clinicians decide on the appropriate level of care and interventions.
  • Better Resource Utilization: Ensures that patients receive the necessary care without overburdening critical care resources.

Note: Confusion, RR and BP are common to CRB-65 and SMART-COP, but SMART-COP includes septic markers (tachycardia, acidosis and hypoxia) as well as CXR findings and albumin. As such, SMART-COP is more applicable to DEM than GP.
