CORRELATION OF THE DOSE INDEX AND COPD ASSESSMENT TEST (CAT) SCORE IN PREDICTING RECURRENT EXACERBATIONS IN CHRONIC OBSTRUCTIVE PULMONARY DISEASE

Abstract

Background: Chronic obstructivepulmonary disease (COPD) is a majorcause of morbidity and mortalityworldwide, with acuteexacerbationscontributing significantly to diseaseprogression, recurrent hospitalizations,impaired quality of life, and increasedhealthcare costs. Accurate assessment ofdisease severity and prediction of futureexacerbations are essential for optimizingpatient management. This study evaluatedthe relationship between the DOSE Indexand CAT score and their ability to predictclinical outcomes in patients with acute exacerbation of COPD.
