Comparison of Severity Scoring Systems in Community-Acquired Pneumonia

Objective: The aim of this study was to compare the ability of CURB-65, pneumonia severity index and SMART-COP systems to predict 30-day mortality and the need for intensive respiratory and vasopressor support (IVRS). Methods: We included 84 cases with community acquired pneumonia (CAP) and followed up for 30 days. The scores were calculated at admission and associated with the 30-day mortality and the need for intensive respiratory and vasopressor support. Results: The mean age of patients was 58.6±18.7 years. The 30-day mortality level for CAP was 7.1%. Fourteen of 84 patients (16.7%) with CAP were followed in ICU. The area under curve (AUC) values of the three systems (CURB-65, PSI, and SMART-COP) for 30-day mortality were 0.89, 0.89 and 0.91, respectively, and for the need for IRVS was 0.88, 0.91 and 0.93, respectively. Conclusion: The three systems accurately detected the need for IRVS and the 30-day mortality, but none individually demonstrated any advantage over the others
