BODE Index Calculator
Multidimensional Risk Assessment for COPD
The BODE Index is a multidimensional scoring system used to predict the risk of death from Chronic Obstructive Pulmonary Disease (COPD). It provides a more comprehensive assessment than spirometry alone.
The BODE Index evaluates four key domains: Body Mass Index, airflow Obstruction, Dyspnea, and Exercise capacity. Each component is scored from 0-3, with a total possible score of 0-10.

Clinical Interpretation
Based on the calculated BODE Index, the patient is at low risk of mortality.
Estimated Mortality Risk
Approximate 1-year mortality risk: ~5%

BODE Index Scoring System
| Points | BMI (kg/m²) | FEV1 (% predicted) | mMRC Scale | 6-Minute Walk (meters) |
|---|---|---|---|---|
| 0 | >21 | ≥65% | 0-1 | ≥350 |
| 1 | ≤21 | 50-64% | 2 | 250-349 |
| 2 | – | 36-49% | 3 | 150-249 |
| 3 | – | ≤35% | 4 | ≤149 |
Clinical Utility
The BODE Index is better than FEV1 alone at predicting the risk of death from any cause and from respiratory causes among patients with COPD. It helps clinicians:
- Identify high-risk patients who may benefit from more aggressive therapy
- Guide decisions regarding referral for pulmonary rehabilitation
- Assess prognosis and have informed discussions with patients
- Monitor disease progression over time
Important: The BODE Index is a prognostic tool and should not be used as the sole basis for clinical decisions. Always consider the individual patient’s overall clinical picture.
The BODE Index is a multidimensional scoring system used to predict the risk of death from Chronic Obstructive Pulmonary Disease (COPD). Unlike spirometry alone, it provides a more comprehensive assessment by evaluating four key domains:
- B - Body Mass Index (BMI)
- O - Airflow Obstruction (FEV1 % predicted)
- D - Dyspnea (mMRC Dyspnea Scale)
- E - Exercise Capacity (6-minute walk distance)
Each component is scored from 0-3, with a total possible score of 0-10. Higher scores indicate greater disease severity and higher mortality risk.
