Description of intervention(s) / exposure
The study aimed to determine the correlation between the infection of SARS-CoV-2 and the occurrence of respiratory, coagulation, immune and endocrine system disorders. The study will be a retrospective observational design; therefore, no active involvement by participants is required. The study will include adult patients hospitalized for SARS-CoV-2 infection in the Intensive Care Unit of the 4th Military Hospital of Wroclaw in Poland. Audit of medical records of adult patients hospitalized for SARS-CoV-2 infection in the Intensive Care Unit of the 4th Military Hospital of Wroclaw in Poland between June 1st, 2021 to July 31st, 2021.

Demographics, blood type, and mechanical ventilation parameters will be analyzed during the study. Additionally, coagulation tests, blood morphology, markers of kidney injury, thromboelastometry, inflammatory markers such as CRP and PCT (procalcitonin) will be evaluated. Kidney function and the rate of thromboembolic complications will be assessed. The frequency of bacterial and fungal co-infections will be recorded. Additionally, information on chronic diseases (diabetes, hypertension, kidney failure, and nicotine addiction) and medications will be collected.

Statistical methods / analysis
Analyses will be performed using Statistica v.10 (TIBCO Software Inc., USA). Continuously distributed data will be tested for normality using the Shapiro-Wilk and Kolmogorov-Smirnov tests. The critical significance level will be assumed at p<0.05. Qualitative variables (infection type) will be presented as counts (n) and proportions (%). Pearson's chi-square test of independence will be used to assess the association between infection type and 28-day survival. Quantitative variables will be presented in tables as mean values (M) and standard deviations (SD). The significance of differences between mean parameter levels in groups differing in 28-day survival will be verified using Student's t-test. Kaplan-Meier method will be used to evaluate overall survival (OS). The log-rank test will be used to compare the survival curves of the patient group. The results will be considered statistically significant when the p-values were lower than 0.05.

Summary
Brief summary
Assessment of the impact of SARS-CoV-2 infection on the respiratory, coagulation, immune and endocrine system and the frequency of bacterial infections in patients hospitalized in the intensive care unit. This is a retrospective and cross-sectional study among patients who were treated in ICU for COVID-19.

Clinical records and medical documentation obtained during hospitalization of patients in the Department of Anaesthesiology and Intensive Care in the 4th Military Clinical Hospital in Wroclaw in the period from June 1st, 2021 to July 31st, 2021 due to COVID-19 will be evaluated. Apart from the assessment of Sequential Organ Failure Assessment (SOFA), Acute Physiology and Chronic Health Evaluation II (APACHE II), and Simplified Acute Physiology Score II (SAPS II) scales, the selected parameters of the coagulation, hematopoietic, endocrine systems as well as inflammatory and renal parameters will be analyzed. These examinations were taken routinely every day. Ventilation parameters and modes according to the type of ARDS (type H or L) and the effectiveness of the prone position was evaluated. In addition, the study is designed to assess the incidence of bacterial infections, particularly with multi-drug resistant strains, and fungal infections. Medications administered and the incidence of thromboembolic complications were recorded. Additionally, demographic data, BMI, blood group, and the presence of co-morbidities and actual medications will be studied.

Symptomatic respiratory distress in COVID-19 often leads to the development of acute respiratory distress syndrome (ARDS) and the need for mechanical ventilation. In addition, bacterial superinfection occurs in patients with immunological disorders and in the course of steroid therapy. Increasingly, co-infections with multidrug-resistant strains are observed, which further worsen prognosis. Thus, patients infected with SARS-CoV-2 have an excessive susceptibility to activation of the coagulation system, hypertension, insulin resistance, alveolar edema, and ARDS. We would like to ensure that participants received interventions regardless of their involvement in the study.
