Es un índice multidimensional diseñado para evaluar los riesgos clínicos en personas con enfermedad pulmonar obstructiva crónica (EPOC).
Combina cuatro variables importantes en una sola puntuación:
(B) índice de masa corporal;
(O) obstrucción al flujo aéreo medido por el volumen espiratorio forzado en un segundo (FEV1),
(D), disnea medido por la a escala Medical Research Council (MRC) modificada y
(E) la capacidad de ejercicio medida por la prueba de la marcha en 6 minutos (TM6M).
Cada componente se clasifica y una puntuación de hasta 10 se obtiene, con puntuaciones más altas indican un mayor riesgo.
El índice BODE refleja el impacto de los factores pulmonar y extrapulmonar en el pronóstico y la sobrevida en la EPOC.
The BODE Index: A Tool for Predicting COPD Mortality
Although clinical evidence is limited regarding the prognosis of COPD (meaning how long people live after diagnosis), the BODE Index has been developed as a practical tool to measure a patient's degree of lung impairment, capture their perception of respiratory symptoms, and express how the disease negatively affects the entire body as a system.
BODE takes into account body mass index (BMI), airway obstruction (as measured by FEV1), dyspnea(as measured by the MMRC dyspnea scale) and exercise tolerance (as measured by the 6-minute walk test). In addition, researchers say the BODE Index is a better predictor of COPD mortality than FEV1 alone.
