BODE Index Calculator

BODE Index Calculator for Pulmonology. Higher 0-10 totals indicate greater multidimensional COPD burden in the original prognostic framework. Standardized walk testing, appropriate spirometry and documented mMRC grading matter. Historical cohort survival is not an individual forecast.

For shared guidance on choosing a tool and documenting results, read the clinical calculator workflow.

How this calculator works

BODE adds airflow obstruction, standardized six-minute walking distance, documented mMRC grade and BMI. FEV1 lower limits are 65, 50 and 36%; distance lower limits are 350, 250 and 150 m. BMI at most 21 earns one point.

When to use this calculator

Use to contextualize prognosis in stable COPD, not during an acute exacerbation or as an isolated treatment-selection rule.

Inputs used

  • FEV1 (% predicted)
  • Six-minute walk distance (m)
  • Documented mMRC grade
  • BMI (kg/m2)

Clinical interpretation

Higher 0-10 totals indicate greater multidimensional COPD burden in the original prognostic framework. Standardized walk testing, appropriate spirometry and documented mMRC grading matter. Historical cohort survival is not an individual forecast.

Worked example

Fictional teaching case. FEV1 (% predicted): 42; Six-minute walk distance (m): 240; Documented mMRC grade: 3; BMI (kg/m2): 19. Result: 7 points. BODE index (0-10). Contributions in assessment order: 2 + 2 + 2 + 1 = 7. This is a risk estimate, not a diagnosis, a personal survival prediction, or an automatic treatment/discharge decision. The six-minute walk requires standardized administration; this is not an acute exacerbation score.

Limitations and safety notes

The integer bands in the original table are implemented as continuous lower-limit intervals for decimal measurements, with no gaps. Enter mMRC as an integer grade, not a decimal or copied questionnaire. Survival estimates from the original cohort are not personal predictions.

  • Prefer original validation studies for scoring systems and prediction tools.
  • Use current specialty society guidance, transplant allocation policy, public health guidance, or regulator resources when they govern clinical use.
  • Include limitations and safety notes when a calculator is population-specific, context-dependent, or unsuitable as a standalone decision tool.
