Abstract

Background: Determining prognosis in community acquired pneumonia (CAP), is very important. Many scores are introduced up to now for prediction of pneumonia prognosis like SMART-COP. Objective: To evaluate validity of SMART-COP score in prognosis and severity of CAP in emergency department (ED). Methods: All patients older than 18 years old with clinical suspicion of CAP (meeting the inclusion criteria), were enrolled in our study. In this prospective study, patients were admitted to the ED of a tertiary referral center. Hospital length of stay, rate of intensive care unit (ICU) admission, mortality rate, number of intensive respiratory or vasopressor support (IRVS) use, patients' SMART-COP scores and all demographic data were recorded. Validity of SMART-COP in the prediction of IRVS rate and its correlation with other variables were determined. Results: In this study, 47.6% and 52.4% of patients were females and males respectively. The mean age of patients was 68.13 ± 16.60 years old. The mean hospital length of stay was 13.49 ± 5.62 days. Of all patients entered in our study, 55 cases (38.5%) needed ICU admission, 29 cases (20.3%) were expired within 1 month and 44 cases (30.8%) needed IRVS during their treatment. SMART-COP ≥5 (high risk CAP) accurately predicted the rate of ICU admission, one-month mortality and IRVS need (p-value = 0.001). Conclusions: SMART-COP≥5 had a high sensitivity and specificity in the prediction of patients' prognosis with severe CAP in the ED. © 2018 Elsevier Inc.
