Scoring the BODE Index

The BODE is a multidimensional index designed to assess clinical risk in people with chronic obstructive pulmonary disease (COPD). It combines four important variables into a single score: (B) body mass index; (O) airflow obstruction measured by the forced expiratory volume in one second (FEV1); (D) dyspnoea measured by the modified Medical Research Council (MRC) scale; and (E) exercise capacity measured by the 6-minute walk distance (6MWD). Each component is graded and a score out of 10 is obtained, with higher scores indicating greater risk. The BODE index reflects the impact of both pulmonary and extrapulmonary factors on prognosis and survival in COPD.

Indications for the Six-Minute Walk Test (6MWT)

The American Thoracic Society Pulmonary Function Standards Committee developed guidelines for the 6MWT in clinical settings. The 6MWT was chosen because it is easier to administer, better tolerated, and better reflects activities of daily living than other walk tests.
