SCREENING FOR CHRONIC OBSTRUCTIVE PULMONARY DISEASE IN HIGH-RISK PATIENTS USING THE PUMA SCORE
Main Article Content
Abstract
Objective: To determine the optimal cut-off point of the PUMA score in COPD screening for patients visiting the internal medicine clinic. Method: Prospective cross-sectional descriptive study on patients at risk of COPD at the internal medicine clinic, Trung Vuong hospital, Ho Chi Minh city. Using the PUMA questionnaire for screening, and using the FEV1/FVC standard after bronchodilator test < 0.7 on spirometry to diagnose COPD. Analyzing ROC curve, sensitivity, specificity, positive and negative predictive value to choose the optimal cut-off point. Results: Of the 131 patients enrolled in the study, 16 patients (12.2%) were diagnosed with COPD. With a cut-off point ≥ 5 points of the PUMA score, the area under the ROC curve (AUC) was 0.68, sensitivity 100%, specificity 23.50%, positive predictive value 15.40%, negative predictive value 100%. Conclusion: The PUMA score with a cut-off point ≥ 5 points is a good tool for early screening of chronic obstructive pulmonary disease in Vietnam.
