SMART-COP Score Calculator

Enter eight clinical parameters to get the SMART-COP score and predict whether a CAP patient needs intensive respiratory or vasopressor support.

Patient Parameters

All fields required. Age affects respiratory rate and oxygenation thresholds.

S Systolic Blood Pressure < 90 mmHg?
M Multilobar Involvement on Chest X-ray?
A Serum Albumin < 3.5 g/dL (35 g/L)?
R Respiratory Rate Elevated? (enter age first)
T Heart Rate ≥ 125 bpm?
C New-Onset Confusion?
O Low Oxygenation? (enter age first)
P Arterial pH < 7.35?

Fill in the parameters and click Calculate to see the SMART-COP score and IRVS risk.

Summary

Enter eight clinical parameters to get the SMART-COP score and predict whether a CAP patient needs intensive respiratory or vasopressor support.

How it works

  1. Enter the patient's systolic blood pressure, multilobar involvement, albumin level, and respiratory rate.
  2. Provide the tachycardia status, confusion assessment, oxygenation data, and arterial pH.
  3. Each parameter contributes 1–2 points; albumin and oxygenation are age-adjusted.
  4. Total score is computed instantly with an IRVS risk category.
  5. Use the result alongside clinical judgment to guide ICU triage decisions.

Use cases

  • Triage adults admitted with community-acquired pneumonia to standard ward vs. ICU.
  • Identify high-risk patients who may need early vasopressor or ventilatory support.
  • Supplement CURB-65 or PSI/PORT scoring with an IRVS-specific prediction tool.
  • Quickly reassess risk at the bedside when a patient's condition changes.
  • Teach medical students and residents CAP severity stratification.
  • Document objective severity assessment in clinical notes.
