How Important Are Hematological Parameters in the Prognosis of Severe Covid-19 Patients?

Department of Infectious Disease and Clinical Microbiology

It is aimed to reveal the treatment and prognostic values by evaluating the differences in hematological parameters and indices, especially in dead Covid-19 cases.

Material Method: It is planned to retrospectively examine the hemogram parameters of 125 male, 44 female and 169 critical Covid-19 patients hospitalized between 01.03.2020 and 31.12.2021. Subjects were divided into 2 groups as deceased (77) and living (92) patients according to demographic data such as age and gender.

Statistical evaluation: All analyzes were SPSS 25.0, Kolmogorov Smirnov test was used to determine distribution, median and interquartile range (Tukey's Hinges Percentile) were used to summarize variables. The differences between the Independent-Samples Mann Whitney U Test and the data of the patient groups and the optimal cut-off values, sensitivity and specificity values will be determined by ROC analysis. It will be considered statistically significant when the p value is below 0.05 (with the two-tailed test)

The aim of this study is to examine the effectiveness of routine laboratory complete blood count parameters and rates as diagnostic and prognostic criteria in severe COVID-19.
