The Prognostic Value of SOFA, qSOFA, CURB-65 and 4C Mortality Scoring Systems in COVID-19 Pneumonia Patients Presenting to the Emergency Department

Aim: The aim of this study is to investigate the relationship between mortality and CURB-65, SOFA, qSOFA, and 4C mortality scores in COVID-19 patients presenting to the emergency department. Material and Methods: This prospective observational study included patients presenting to the emergency department who tested positive for COVID-19 PCR and were diagnosed with pneumonia on chest CT. Results: A total of 160 patients, of whom 81 (50.6%) were female, were included in the study. Examination of patient mortality within 30 days revealed that 50 (32.3%) patients died. According to the SOFA score, mortality was observed in 2 (9.1%) of patients with scores of 0-1, 13 (17.8%) of those with scores of 2-3, 9(32.1%) of those with scores of 4-5, 14 (66.7%) of those with scores of 6-7, 9 (75%) of those with scores of 8-9, 1 (66.7%) of those with scores of 10-11, and in 1 patient (100%) with a score of 12-14. According to the qSOFA score, mortality was observed in 2 (10%) of patients with a score of 0, 7 (13%) with a score of 1, 25 (42.4%) with a score of 2, and 16 (59.3%) with a score of 3. According to the CURB-65 score, mortality was observed in 4 (19%) of patients with scores of 0-1, 5 (9.1%) of those with a score of 2, and 41 (48.8%) of those with scores of 3 or higher. Regarding the 4C mortality score, mortality was not observed in any of the 5 patients with scores of 0-3, while mortality occurred in 1 (5.3%) of those with scores of 48, 11 (19.6%) of those with scores of 9-14, and in 38 (47.5%) of the remaining patients. Statistically significant relationships were found between SOFA, qSOFA, CURB-65, and 4C mortality scores and mortality (p
