BODE index

BODE Index

The BODE Index (pronounced /boʊd/), is a multidimensional grading system used in the field of medicine to assess the severity of Chronic Obstructive Pulmonary Disease (COPD). The term "BODE" is an acronym derived from four factors: Body mass index (BMI), Obstruction of the airways, Dyspnea (shortness of breath), and Exercise capacity.

Etymology

The term "BODE" is an acronym that stands for Body mass index, Obstruction, Dyspnea, and Exercise capacity. It was first introduced in a 2004 study by Celli et al., published in the New England Journal of Medicine.

Body Mass Index

The Body Mass Index (BMI) is a measure that uses the height and weight of a person to determine their body fat. In the BODE Index, a lower BMI score indicates a higher risk of mortality.

Obstruction

In the context of the BODE Index, Obstruction refers to the degree of obstruction in the airways, typically measured using spirometry to determine the forced expiratory volume in one second (FEV1).

Dyspnea

Dyspnea is a term used in medicine to describe the sensation of shortness of breath, a common symptom in COPD patients. The BODE Index uses the Modified Medical Research Council (MMRC) Dyspnea Scale to assess this factor.

Exercise Capacity

Exercise Capacity is assessed in the BODE Index using the six-minute walk test (6MWT). This test measures the distance that a patient can quickly walk on a flat, hard surface in a period of six minutes.
