CORRELATION OF CAT SCORE WITH BODE INDEX IN PATIENTS WITH CHRONIC OBSTRUCTIVE PULMONARY DISEASE

Abstract

Objective: To determine correlation of Chronic Obstructive Pulmonary disease Assessment Test score with Body mass index, airflow Obstruction, Dyspnea and Exercise index in patients with stage II and III chronic obstructive pulmonary disease.

Study Design: Cross-sectional study.

Place and Duration of Study: Department of Pulmonology, Fauji Foundation Hospital, Rawalpindi, Pakistan from Jul, 2017 to Dec 2017.

Methodology: This study was conducted on Stage II and III chronic obstructive pulmonary disease patients. We analyzed demographic variables; Body mass index (BMI), 6-min walktest, modified Medical Research Council dyspnea scale to calculate Body mass index, airflow Obstruction, Dyspnea and Exercise index score. Spirometry was performed on each patient. The chronic obstructive pulmonary disease Assessment Test was used to assess symptoms of these subjects.

Results: A total of 80 subjects participated in the study with mean age of 58.5 ± 8.0 years. The mean chronic obstructive pulmonary disease Assessment Test and Body mass index, airflow Obstruction, Dyspnea and Exercise scores were 25.5 ± 7.7 and 5.14 ± 2.0 respectively. Pearson’s correlation showed positive correlation between chronic obstructive pulmonary disease Assessment Test score and Body mass index, airflow Obstruction, Dyspnea and Exercise score (r2=0.810, p=0.0001). A positive correlation coefficient was obtained between chronic obstructive pulmonary disease Assessment Test score and Body mass index, airflow Obstruction, Dyspnea and Exercise class (r2=0.784, p=0.00012).

Conclusion: Chronic obstructive pulmonary disease Assessment Test score correlated positively with Body mass index, airflow Obstruction, Dyspnea and Exercise index score in stage II and stage III chronic obstructive pulmonary disease patients.
