\begin{abstract}
The aim of this study is to evaluate the performance of CURB-65, qSOFA,
and NEWS2 scores in predicting mortality in COVID-19 patients and to
investigate potential components of a COVID-19-specific prognostic
score. A total of 502 patients diagnosed with severe COVID-19 in the
emergency department of a pandemic hospital between 01.04.2020 and
01.02.2021 and hospitalized in the intensive care unit were analyzed
retrospectively. Demographic, clinical and laboratory data of the
patients were obtained from the hospital registry system. The CURB-65,
qSOFA and NEWS2 scores of each patient were calculated separately. These
patients were divided into two groups as those who survived and those
who died. All parameters and calculated risk scores were statistically
compared between these two groups. When the CURB-65, NEWS2, qSOFA scores
were compared between the two patient groups, a significant difference
was found (P\textless{}0.001). Compared with CURB-65 and qSOFA,
sensitivity of 92.3\% and NPV of 90.2\% were detected when NEWS2[?]8. The
CURBLFPC score reached the highest mortality predictive power among
other scores with an AUC value of 0.91. Because the NEWS2 score is
superior to CURB-65 and qSOFA for predicting mortality, it can be used
in the triage of severe COVID-19 patients, predicting prognosis and
improving outcomes.In more comprehensive and prospective studies, new
models such as CURBFPC can be created and a specific prognostic score
for COVID-19 can be developed.%
