On the basis of a call for applications of the Government of Hungary of 24 February 2017, the National Office of the Chief Medical Officer, the National Institute for Health Development, the Semmelweis University, the State Health Care Center and the consortium of the National Health Insurance Fund Manager have carried out a detailed feasibility study of the priority project EFOP-1.8.0-VEKOP-17 on the professional methodological development of the health care system, and committed to its implementation. The state of health of the Hungarian population is currently below the level expected on the basis of Hungary’s socio-economic development. In addition to cancer and cardiovascular diseases, the incidence of mental illness is also high, all of which are a major burden for the country. A significant proportion of the diseases listed are due to poor lifestyles and therefore significant improvements in the health behaviour of the population need to be achieved and an adequate physical, social, economic and legal environment is ensured. Primary care is the only segment of the health care system capable of connecting with the population as a whole, so at this level of care the health behaviour of the population can be most effectively influenced. At this level of supply, equal access for the general public to services of nearly the same quality can be achieved in practice. Primary care can be improved by expanding the range of near-home services, by strengthening the role of primary care as gatekeeper, by increasing the operational efficiency of primary care practices, by shifting the healthcare of the population from more expensive hospital care to primary and outpatient care. This requires, on the one hand, the development of current service methodologies and the service portfolio and, on the other hand, the capacity, knowledge, capacity, preventive approach and attitude of the available staff of general practitioners, qualified nurses and specialists and protective women. In order to develop public health-conscious behaviour and early detection of diseases and health risks, it is important to include public health and preventive services as an integral part of primary care. The organisation of employee competences and the integration of professionals providing new types of services can widen the range of definitive services and benefits available locally. According to the World Health Organisation (WHO), every tenth patient in well-equipped hospitals in advanced health countries develops an adverse event, with 1 % of the patients affected dying. According to patient safety research, the events are mainly due to planning shortcomings (e.g. inadequate working time schedules, storage conditions, drug distribution activities) or factors affecting implementation (e.g. congestion, stress, time pressure), with only 10-15 % of individual responsibility being established. Patient safety means tasks and responsibilities not only from the side of the care system, but also from the patient’s and relatives’ side. The effective reduction of adverse events can be achieved by mapping the sources of threats inherent in systems and processes, as well as the impacts from the operational environment, and reducing their significance, not by identifying and punishing those who have committed errors. With regard to patient safety risks, it is always possible to identify recommended behaviours and actions to help patients manage these risks. It is of utmost importance that the public obtain adequate information on the patient safety factors that can be identified during healthcare, while learning to learn behaviours that can help to avoid adverse events themselves. A summary of the project’s objectives is presented in the tables on the following page.
