BODE Index Calculator Online

The BODE Index Calculator provides a quantitative measure of COPD severity, which has been shown to be a more effective predictor of mortality than FEV1 alone. By evaluating multiple dimensions of a patient's health, it offers a comprehensive overview that aids in critical decision-making and patient education.

Formula of BODE Index Calculator

Here's how you calculate the BODE index:

• Body Mass Index (BMI):
  • 0 points if BMI > 21
  • 1 point if BMI ≤ 21
• Obstruction (FEV1 % predicted):
  • 0 points if FEV1 ≥ 65%
  • 1 point if FEV1 50-64%
  • 2 points if FEV1 36-49%
  • 3 points if FEV1 ≤ 35%
• Dyspnea (MMRC Dyspnea Scale):
  • 0 points if MMRC 0-1
  • 1 point if MMRC 2
  • 2 points if MMRC 3
  • 3 points if MMRC 4
• Exercise capacity (6-minute walk distance):
  • 0 points if walk distance > 350 meters
  • 1 point if walk distance 250-349 meters
  • 2 points if walk distance 150-249 meters
  • 3 points if walk distance < 150 meters

To calculate the BODE index, sum the points from each category. The formula is:

BODE Index = BMI Points + Obstruction Points + Dyspnea Points + Exercise Capacity Points

Example of BODE Index Calculator

Consider a patient with a BMI of 20, FEV1 of 45%, an MMRC grade of 3, and a 6-minute walk distance of 200 meters. Calculating each category:

• BMI: 1 point
• Obstruction: 2 points
• Dyspnea: 2 points
• Exercise Capacity: 2 points

Total BODE Index: 7 points (indicative of severe COPD and higher risk of mortality).
