BODE index: A predictor of hospitalization and severity in chronic obstructive pulmonary disease patients

The BODE index (Body Mass Index, Airflow Obstruction, Dyspnoea, Exercise tolerance) as a predictor of hospitalization and disease severity among Chronic obstructive lung disease (COPD) patients is of interest. Each patient’s BODE index was calculated for 120 cases classified by the GOLD criteria. A strong correlation was found between the BODE index, GOLD grades and hospitalization frequency. ROC analysis confirmed that the BODE index significantly predicts severe COPD, with an AUC of 0.716. A cut-off value of >3 showed moderate sensitivity (62.1%) and specificity (62.6%) for predicting hospital admissions. Thus, the BODE index is a reliable tool for evaluating COPD severity and hospitalization risk, aligning closely with GOLD spirometry grades.
