The purpose of this dissertation is to explore the contemporary area of information technologies employed in health care (eHealth). Focusing on the systems already employed in the Czech Republic, it aims to analyse them, to quantify expenditures of their introduction and maximum benefits derived from these, as well as to evaluate their real current profit. Out of the three existing national systems, this dissertation concentrates on the two only (eRecept, ePACS), as it became impossible to evaluate the third -- IZIP system due to scarcity of the relevant information available. In the field of expenditures not only generally published numbers are taken into consideration, but this dissertation also evaluates the expenditures of other subjects involved (IT systems producers, health care providers, etc.). As the first dissertation in the Czech Republic it quantifies benefits derived from the existing eHealth systems and unlike foreign theses it greatly emphasizes just the expenditures of other subjects involved. Included in this dissertation is also the evaluation of achievements of the eHealth systems in the Czech Republic complete with supposed grounds for this situation. This dissertation also recommends courses of action for contractors of these systems to ensure future basis for more economical and successful eHealth systems. These recommendations are mainly based on analysis of development of the existing national eHealth systems. For the complex evaluation of the costs, maximum of possible and real benefit of the individual eHealth systems the research approach adopted in this dissertation includes descriptive method and SWOT analysis, extrapolation and abstraction, comparative and factor analysis.

A large number of attitudes and methods of dealing with health service, or, more precisely, health, occur in theory and practice. The aim is to examine the efficiency of the implementation of the current projects, i.e. efficient application of tools of managing the quality of health. Theoretical rationales characterize understanding of conception of the quality of health especially in the sphere of health service. Moreover, this part introduces selected tools of managing the quality of health. The analytical part is focused on the institutional environment in connection with current challanges of eHealth implementation. The Central Repository of electronic prescriptions as the tool of managing the quality of health and the basis for ePrescription is one of the mentined challenges. The final part concerns with future trends in the Central Repository of electronic prescriptions and international projects, e.g. epSOS project. The EU is established on the principle of benchmarking, among other things. Possible future advances need to be considered in the context of foreign projects. For this reason, the Danish eHealth situation is included in the conclusion.
