Significantly improving the use of data in public administration is a key objective of the 2014-2020 programming period. We want to treat data as a scarce resource. The data layer is therefore given significant attention in the e-Government architecture. The main aim is to ensure functional data integration between individual systems of public administration, including regular replication of high-quality and consolidated transaction data into data repositories. Better data means the possibility of obtaining quality information, the resulting “insights” which in turn serve as a basis for knowledge creation and better decision making. If better decision-making is made in public administration, this will have a positive impact on the governance performance and the state of the various government sectors. Public administrations need to build up sufficient capacity to work with data. It is very important to understand in detail the logic (ontologies) of managed data, to create and maintain data models, to catalogue metadata and paradata, to understand the links between different systems and to support the improvement of data quality in public administration information systems.The key issue is which data need to be collected and on the basis of which outputs public administration should decide. As part of the National Concept of Informatisation of Public Administration 2016, the topic was addressed by Working Group K9.4 Better Data, which proposed a system solution for data management. The concept presented in the strategic priority Data Management represents the application of the idea of a “Data-driven state” of a state operating on the basis of the use of data and the precise management of the entire data lifecycle. Since 1 January 2018, the eHealth System has been in live operation, currently referred to as eHealth.However, the frequently used service involving a doctor, patient and employer – claiming a benefit from sickness insurance – is still paper and procedurally complex not only for the patient, but also for social insurance officials. The reason for carrying out this feasibility study is the electronisation of this functionality and thus aj:ušetrenia time for a citizen to save time for a doctor to save time for the employer to allow employers to react promptly to changes in staff status and to monitor temporary incapacity for work of their employees (place of stay and scope of departures) to accelerate the sale of information from the attending physician to the relevant social insurance departments, as the delivery of paper-based amendments by post will be excluded. It touches on all the sickness benefits issued by the doctor and patient The existing demand for the reduction of the administration of all interested parties, the lack of time to devote to a patient who needs to provide the ZS Deleting of the rewriting of manually completed data on the part of all involved subjects. Extending the possibilities to all attested doctors, thus degrading a significant part of the administration at the general practitioner and at the same time eliminating the unnecessary treking of the ill patient of the employer, e.g. information about the place. The aim of the system, which describes a study of the feasibility of: a demanding and lengthy administration for a doctor in patient enrolment, such as PN time-testing, time-consuming procedural actions associated with the administration of forms (procurement and delivery) to minimise the time of the social insurance doctor’s review in the doctor’s ambulance and the replacement of the procedures through electronic time-saving services for the patient with PN transmission and reporting to the job, fully eliminating the visits of the doctor at the turn of the citizen and, at the same time, eliminating all the administrative tasks associated with it on the part of the doctor, patient, employer and social insurance, the creation of a new service to improve the safety of the employer, for example, to improve the information of the employer in order to improve the safety of the employer, for example, to ensure that all the administrative tasks associated with the doctor’s side, the patient, the employer and the social insurance company, are used to improve the safety of the new health care service. The project consists of two parts: the modification of health systems, where electronic data on the occurrence of incapacity for work or the fulfilment of conditions for other benefits of NP will be recorded, modification of SP systems, power departments and, in part, employers, where the data are processed. The subject of funding is the first part, i.e. the modification of health systems (CHP, eHealth), and the SP will start implementation within the project 8 months after the start of implementation on the NCZI side (after the preparation of the first interfaces). The project also foresees a pilot operation involving representatives of all actors.
