Comparative analysis between PUMA and CAPTURE questionnaires for chronic obstructive pulmonary disease (COPD)...

Area of Science:

• Respiratory Medicine
• Public Health
• Diagnostic Tools

Background:

• Chronic obstructive pulmonary disease (COPD) is a growing global health concern, particularly with an aging population.
• Indonesia lacks comparative studies on the effectiveness of available COPD screening tools like PUMA and CAPTURE.
• Effective screening is crucial for early detection and management of COPD in high-risk populations.

Purpose of the Study:

• To compare the effectiveness of the PUMA and CAPTURE questionnaires for COPD screening in Indonesian smokers.
• To assess the sensitivity and specificity of both questionnaires in identifying obstructive patterns.

Main Methods:

• A cross-sectional study involving 76 smokers aged over 40 was conducted in Medan, Indonesia.
• Participants completed the PUMA and CAPTURE questionnaires via face-to-face interviews.
• Spirometry tests were performed to confirm obstructive patterns, with 50 participants showing such results.

Main Results:

• The PUMA questionnaire (cut-off ≥6) demonstrated a sensitivity of 72.55% and a specificity of 84%.
• The CAPTURE questionnaire (cut-off ≥4) yielded a sensitivity of 70.83% and a specificity of 64.29%.
• PUMA exhibited higher specificity and overall better performance in this cohort.

Conclusions:

• The PUMA questionnaire appears to be a more efficient screening tool for COPD in Indonesian smokers than the CAPTURE questionnaire.
• These findings support the use of PUMA for early COPD detection in similar populations.
• Further research could explore broader implementation and validation of PUMA in diverse Indonesian demographics.
