About this calculator

Overview

The BODE Index is a multidimensional grading system used to predict mortality in patients with Chronic Obstructive Pulmonary Disease (COPD). It is a better predictor of the risk of death than FEV1 alone, as it captures the systemic impact of the disease (BMI, dyspnea, and exercise capacity).

💡

Pro Tips

Include the total body mass including muscle; low weight in COPD often reflects systemic inflammation and muscle wasting.
The 6-minute walk distance (6MWD) should be performed on a flat circuit or corridor.
High BODE scores may indicate that a patient should be considered for lung transplantation evaluation.

Fun Facts

"A score of 7-10 is associated with a 48% mortality at 52 months."
"FEV1 (Forced Expiratory Volume) is measured after using a bronchodilator."
"Low BMI (<21) is a significant predictor of poor survival in COPD patients."
"Dyspnea is measured using the Modified Medical Research Council (MMRC) scale."

Formula: BODE = Body Mass Index + Obstruction (FEV1) + Dyspnea (MMRC) + Exercise (6MWD).
