Title : Comparative evaluation of DECAF and BAP 65 scores in predicting outcomes of COPD exacerbations among in patients at Vicente Sotto Memorial Medical Center
Abstract:
Background: Acute exacerbations of chronic obstructive pulmonary disease (AECOPD) significantly contribute to morbidity and mortality worldwide. Accurate prognostic tools are essential for timely risk stratification and management in hospitalized patients.
Objective: This study aimed to compare the predictive performance of DECAF and BAP-65 scores for clinical outcomes, specifically in-hospital mortality and the need for mechanical ventilation, among Filipino patients admitted with AECOPD at Vicente Sotto Memorial Medical Center.
Methods: Eighty patients with AECOPD were prospectively evaluated. The DECAF and BAP-65 scores were calculated on admission. Clinical outcomes, including in-hospital mortality and mechanical ventilation requirement, were recorded. Sensitivity, specificity, positive predictive value, and negative predictive value of each score were analyzed and compared.
Results: DECAF demonstrated higher sensitivity in predicting mortality (97.44%) compared to BAP-65 (69.23%), though with lower specificity (26.83% vs. 60.98%). DECAF also showed excellent predictive accuracy for mechanical ventilation, with sensitivity and specificity of 95.71% and 90%, respectively, surpassing BAP-65’s 58.57% and 80%. Positive predictive values were similarly high for both scores in mechanical ventilation prediction, but DECAF’s negative predictive value (75%) was markedly better than BAP-65’s (21.62%). These results suggest DECAF is more effective in identifying high-risk patients requiring intensive care, while BAP-65 may be useful for rapid bedside risk assessment where resources are limited.
Conclusion: Both DECAF and BAP-65 scores are valuable in predicting mortality and mechanical ventilation among hospitalized AECOPD patients. DECAF’s superior sensitivity and specificity make it the preferred tool for comprehensive risk assessment in resource-equipped settings, while BAP-65’s ease of use supports its application in resource-limited contexts.
