| الوصف: | The paper dwells on certain mathematical models showing how epidemics develop, namely, logistic ones, SIR-model, and some others There is also a review of articles that focus on such models showing dynamics of incidence with COVID-19 infection These models are often successfully applied for data collected in a whole country but on a regional level there are difficulties due to peculiarities of calculating mortality figures in Russia In this case regression models can be useful with their obvious advantage at the initial stage in an epidemic process They also include exogenous variables that influence mortality, for example, a number of doctors and nurses per a hospital, how well hospitals are equipped with ALV devices, and a number of available beds in them Our research goal was to build up a linear regression model that could be used as a basis for estimating regional mortality caused by COVID-19 as well as for more efficient distribution of all the resources mentioned above The model is built as per a set of resource parameters including data on «active cases» Preliminary three variables that showed data on resources available to communicable diseases departments in hospitals were transformed into a new single one via linear transformation Then the model was tested on a training sample containing an endogenous variable on mortality and four factor ones including prevalence of active virus carriers Regions were included into training data with different lags;they were included into such daily samples when death cases were registered rarely Then the estimated model was applied with other values It turned out to be quite efficient in estimating COVID-induced mortality for regions from trainings samples as well as for several others (for certain intervals) As a result, we built a regression model and estimated its precision;the model showed a relation between mortality in a region and prevalence of active SARS-CoV-2 carriers and availability of resources to hospitals in it It can be useful when these resources are distributed It can also be used to build SIRD, SEIR, and SEIRF models at a regional level when choosing parameters in them related to mortality A methodology itself that can be similarly applied for other epidemic processes also deserves certain attention © Stepanov V S , 2020 |
