Body mass index, obstruction of the airflow, dyspnea, and exercise capacity index as predictor of the severity of exacerbations and systemic involvement in patients with COPD

Abstract


Background: Allocation of the limited resources to the needed patients and decision making regarding timely interventions demand development of a reliable, cost effective, simple assessment tool. Several studies propose body-mass index, airflow obstruction, dyspnea, and exercise (BODE) index for this purpose in patients with Chronic obstructive pulmonary disease (COPD). The objective of this study was to assess the utility of BODE index to predict the severity of exacerbations and systemic involvement in COPD.

Methods: A Present hospital based cross sectional study was carried out among 100 COPD patients. BODE index was used to assess the patients and its association was studied with various variables. The data was analyzed using one-way analysis of variance (ANOVA) test.

Results: As the body index class of severity increases, the number of hospitalizations required in the past also increases and this association is statistically significant. As the severity of the disease increased as indicated by the class the mean number of exacerbations in the past increased and this association was found out to be statistically significant. As the severity of the disease increased as indicated by the class level, the mean number of days of hospitalization increased. But this increase was of small difference and hence on one-way ANOVA test was not found out to be statistically significant. As the pack years increases, the BODE index increases significantly (p value <0.001).  As the severity of the disease increased, the mean body mass index decreased. Haemoglobin level was found to decrease with increase in BODE index class of severity. This association was statistically significant.

Conclusions: The BODE index has been found to be a very good tool to assess the prognosis of COPD as well as severity of acute exacerbations.
