Economic Aspects of the Management of SARS-CoV-2-caused Viral Pneumonia

Abstract

Study Objective: To conduct a cost analysis of the management of patients with viral pneumonia caused by SARS-CoV-2, and to develop nosological models of patients in order to optimise medical fees. Study Design: Statistical and economic study. Material and Methods. We studied 50,539 completed hospitalisations of patients with viral pneumonia caused by SARS-CoV-2 during a period from March 2020 to March 2021 in Municipal Clinical Hospital No. 15 named after O.M. Filatov. Using an expert evaluation, we found out 5 nosological models of patients and calculated mean duration of hospitalisation, confidence intervals (95% CI), and fee parameters using actual costs (cost of one bed-day and completed therapy). Study Results. We managed to prove the hypothesis, according to which correctness of analysis of actual costs of therapy and precise prognosis depend on the differentiation of cases of SARS-CoV-2-caused viral pneumonia using nosological models of a patient, nosological forms, and disease severity. We developed nosological models of a patient; identified a range of cost of therapy; and calculated corresponding relative factors. Conclusion. The cost of management of patients with viral pneumonia caused by SARS-CoV-2 should be analysed and planned depending on nosological models grouped on the basis of common causation of the disease, presence or absence of complications (pneumonia), presence of comorbidities and surgeries, and condition of patients. The most expensive is the management of patients with COVID-19 and npneumonia and surgery. Keywords: cost of management, nosological model, SARS-CoV-2, viral pneumonia.
