Today, in the field of healthcare of the leading countries of the world there is a technological breakthrough due to the use of modern electronic systems. Thanks to the use of medical electronic technologies, it is possible to improve the quality of medical and pharmaceutical care for all segments of the population. The eHealth system provides opportunities for direct participation of patients in their health, which involves organization of a healthy lifestyle and disease prevention. The aim of the study was to analyze the experience of implementation of mobile medical applications and electronic medical systems within eHealth in the healthcare systems of the leading countries of the world and Ukraine.Materials and Methods of the Ministry of Health of Ukraine, FDA, WHO, NHS, ABI Research and other open information databases and statistical agencies were used in the work. The analytical, comparative and generalization of scientific information methods were chosen for the research.Results and Discussion. Modern reformation and further development of the healthcare system of Ukraine provides for the introduction of not only government programs of reimbursement, but also the introduction of electronic information systems, mobile applications for medical, pharmaceutical workers and patients at all stages of medical and pharmaceutical care. The integrated implementation of eHealth determines availability of the necessary healthcare management information system, which should have the following components: registers of medical institutions, services, doctors, patients, diagnosis coding system and electronic medical documentation (electronic medical records and prescriptions). Currently, 1472 medical institutions, 24506 doctors and 21068249 patients have joined eHealth in Ukraine.Conclusions. It has been determined that information electronic technologies allow not only to reduce government spending on the healthcare, but also to achieve a reduction in the number of errors in prescriptions, visits to doctors without the necessary needs and decrease the total number of deaths. The introduction of electronic technologies, in particular mobile applications for the national healthcare system in Ukraine should be controlled by state authorities and independent International organizations on the control and development of information electronic systems.
