BODE Index Calculator for COPD Prognosis

Your details

Choose the unit used when reporting your 6-minute walk distance.
Your BMI in kg/m². BMI 21 or below scores 1 point; above 21 scores 0.
kg/m²
Forced expiratory volume in one second as a percentage of the predicted value for your age, sex, height, and ethnicity. Obtained from spirometry.
%
Distance covered in a standardized 6-minute walk test. Scores 0 pts (>=350 m), 1 pt (250-349 m), 2 pts (150-249 m), or 3 pts (<150 m).
m
The Modified Medical Research Council (mMRC) dyspnea scale grades breathlessness from 0 (minimal) to 4 (severe). Grades 0-1 score 0 points; grade 2 scores 1 point; grade 3 scores 2 points; grade 4 scores 3 points.

BODE score 2/10 - low mortality risk.

  • The Quartile 1 (0-2) carries approximately 80% 4-year survival based on the original Celli et al. validation cohort of COPD patients.
  • 6-minute walk distance is below 350 m: pulmonary rehabilitation programs can meaningfully increase exercise capacity.

Next stepDiscuss your BODE score with your care team to set realistic goals. Pulmonary rehabilitation can lower the BODE score and is one of the few interventions proven to improve survival in COPD.
