What does the BODE index score mean for a COPD patient?

The BODE index combines body mass index, airflow obstruction, dyspnea, and exercise capacity into a single score from 0 to 10. Higher scores indicate greater risk of mortality and more severe disease progression, with the score used to estimate four-year survival probability.

Can the BODE index be calculated without a 6-minute walk test?

No, the 6-minute walk distance is one of the four required inputs for the BODE index. The tool will not produce a result unless all fields, including the walk distance and MRC dyspnea rating, are completed.

Is the survival probability provided by this calculator accurate for individual patients?

The estimated probability of surviving four years is derived from the original Celli et al. study population. It serves as a general prognostic guide but should be interpreted alongside other clinical factors and by a healthcare professional.

Does the tool support metric and imperial units for height, weight, and walk distance?

Yes, the interface allows entry of body weight in pounds or kilograms, height in feet, inches, or meters, and 6-minute walk distance in feet or meters, accommodating different measurement preferences.

About this tool

What BODE Index Calculator does

The BODE Index Calculator on MedicalAlgorithms.com evaluates chronic obstructive pulmonary disease (COPD) survival prognosis using the Celli et al. scoring system. Users input age, gender, body weight and height to calculate body mass index, measured and predicted FEV1 values, 6-minute walk distance, and MRC dyspnea rating. The tool returns the BODE index score, an estimated 4-year survival probability, and an interpretation field, allowing immediate assessment without mandatory registration or payment.

Step by step

How to use the MedicalAlgorithms.com BODE Index Calculator

1
Select the patient's gender (Male or Female)
2
Enter the patient's age in years, body weight in pounds or kilograms, and body height in feet, inches, or meters
3
Input the measured FEV1 in liters and the predicted FEV1 in liters to determine FEV1 as a percentage of predicted
4
Provide the 6-minute walk distance in feet or meters and select the MRC dyspnea rating from 0 (none) to 4 (severe)
