Correlation of Composite Indices and COPD Assessment Test in Thai COPD Patients
Background: Chronic obstructive pulmonary disease (COPD) is a common preventable and treatable chronic respiratory diseases. The BODE, ADO, DOSE are the composite indices taking into consideration for prognostication. In addition, COPD assessment test (CAT) score is associated with quality of life, taken for assessing symptoms severity and for personalizing treatments. Objective: To investigate the CAT score in Thai COPD patients according to their BODE, ADO, and DOSE in the influence of clinical parameters and outcomes. Methods: Medical records were reviewed between January 2016 and December 2016. BODE, ADO and DOSE was calculated based on their individual components. Results: Total 125 consecutive COPD patients were recruited. There was difference between CAT score among the GOLD stages classified (P = .02). There was significant difference of CAT between 4 BODE quartiles in cohort (P = .001).Thai COPD patients had the higher ADO index exhibit the higher CAT score than those with the lower ADO index (P = .001). There was no difference in CAT score between COPD with the higher and the lower DOSE index (P = .05). Conclusions: The higher CAT score found in Thai COPD patients with the higher composite indices of BODE and ADO. However, there was no difference in the DOSE index.
