Evaluation of CAT Score in a Cross-Sectional Study of Construction Site Workers with COPD
Abstract:
Pulmonary function
tests (PFTs) are commonly utilised to gauge lung function and diagnose chronic
obstructive pulmonary disease (COPD). The COPD Assessment Test (CAT) is a
questionnaire utilized to evaluate COPD’s impact on health status. This study
aims to examine the relationship between PFT interpretation, COPD severity, and
CAT scores. A retrospective analysis was conducted on PFT results and CAT
scores of 200 construction site workers with COPD. PFTs were categorized into
three severity levels: mild obstruction, moderate obstruction, and severe
obstruction. CAT scores were classified as mild, moderate, or severe based on
predefined thresholds. The distribution of PFT interpretation and CAT scores
within each COPD severity level was calculated. Among the study population, 13%
had mild obstruction, 54% had moderate obstruction, and 33% had severe
obstruction based on PFT interpretation. In terms of CAT scores, all patients
with mild PFT obstruction had mild CAT scores, while those with moderate PFT
obstruction had moderate CAT scores (100%). Similarly, patients with severe PFT
obstruction had severe CAT scores (100%). Overall, the distribution of CAT
scores corresponded with the severity of PFT obstruction. These findings
highlight the usefulness of combining PFT results with CAT scores for a
comprehensive evaluation of COPD severity and its impact on patients’
well-being. Incorporating both PFTs and CAT scores in clinical practice can aid
in treatment decisions and monitoring the progression of COPD.
