The BODE index, for Body-mass index, airflow Obstruction, Dyspnea, and Exercise, is a multidimensional

scoring system In decision theory, a scoring rule provides a summary measure for the evaluation of probabilistic predictions or forecasts. It is applicable to tasks in which predictions assign probabilities to events, i.e. one issues a probability distribution ...

chronic obstructive pulmonary disease Chronic obstructive pulmonary disease (COPD) is a type of progressive lung disease characterized by long-term respiratory symptoms and airflow limitation. The main symptoms include shortness of breath and a cough, which may or may not produce ...

(COPD) and to predict long-term outcomes for them. The index uses the four factors to predict risk of death from the disease. The BODE index will result in a score of zero to ten dependent upon FEV₁ or "forced expiratory volume in one second" (the greatest volume of air that can be breathed out in the first second of a breath), body-mass index, the distance walked in six minutes, and the modified MRC dyspnea scale. Significant weight loss is a bad sign. Results of

spirometry Spirometry (meaning ''the measuring of breath'') is the most common of the pulmonary function tests (PFTs). It measures lung function, specifically the amount (volume) and/or speed (flow) of air that can be inhaled and exhaled. Spirometry is ...

are also good predictors of the future progress of the disease, but they are not as good as the test results of the BODE index.
