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

## TL;DR

The BODE index helps predict hospitalization and severity in COPD patients, aligning with existing severity classifications.

## Contribution

The study confirms the BODE index's effectiveness in predicting COPD severity and hospitalization risk.

## Key findings

- The BODE index strongly correlates with GOLD grades and hospitalization frequency in COPD patients.
- A BODE index cut-off of >3 moderately predicts hospital admissions with 62.1% sensitivity and 62.6% specificity.
- The BODE index aligns closely with GOLD spirometry grades for COPD severity evaluation.

## Abstract

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.
