Using electronic registries to study the COVID-19 pandemic and its consequences

The article analyses systems of electronic information resources (registers and databases) in the field of the healthcare in different countries. Not only do such systems provide information to support the treatment of patients, but they also accumulate large amounts of statistics, thus enabling their qualitative operational analysis. Electronic health systems are particularly popular in the United States, and as regards Europe, in Denmark and Norway. These countries created good conditions for the efficient introduction of new electronic information resources that would store all the accumulated information about the COVID 19 pandemic. The aim of the article is to summarise information on the use of electronic registers and databases to create an information base for the study of the COVID-19 pandemic and its consequences in different countries, and to formulate proposals for the improvement of electronic health systems in Ukraine. On the basis of the results of their research, the authors propose a list of electronic registers that can significantly improve the analysis of both the course and the consequences of the coronavirus disease. The list includes: the register of immunisations, a specialised register of complications after the recovery from COVID-19, a register of tests for the presence of this disease or the recovery, etc., as well as a register of hospitalisation cases.
