Clinical and anamnestic analysis of in-patients with COVID-19 infection hospitalized during one month

Aim to analyze the clinical and anamnestic data of the patients with a confirmed diagnosis of COVID-19 who were hospitalized in the emergency department of the designated COVID-19 hospital of the Clinics of Samara State Medical University during one month and to compare the results with published registries data. 
Material and methods. A retrospective anonymous data sample included patients hospitalized in the emergency department of the designated hospital of the Clinics of Samara State Medical University during a calendar month (01.03.202131.03.2021) with a confirmed diagnosis of COVID-19. A total of 126 patients (57.9% women) were included in the study, the average age was 65.912.8 years. 
Results. Statistically significant differences (p0.05) in age and body mass index, as well as in the proportion of obese patients were obtained depending on the gender of the patients. Almost every hospitalized person had at least one comorbidity, among which the diseases of the cardiovascular system and gastrointestinal tract prevailed. In general, the obtained data are comparable with the international registries. The differences can be explained by the fact that there were no universal criteria for inclusion, except for the confirmed diagnosis of COVID-19, in the analyzed data samples. 
Conclusion. The high frequency of some diseases makes it possible to significantly expand the possibilities of analysis and increase the reliability in identifying the causes affecting the prognosis in a particular region. The clinical and anamnestic features of a patient may allow individualizing the prognostic assumptions.
