Introduction. Healthcare workers are at a high risk of emotional burnout due to their professional activities associated with constant mental and intellectual stress. The importance of timely diagnosed psychoemotional burnout syndrome (PEBS) determines the need to develop measures for its prevention. Material and methods. We have studied the working conditions, health status of healthcare workers; the indices of relative risk and etiological component of the contribution of work environment and the work process factors to the development of the identified pathology were calculated; the probability of the development of PEBS based on diagnostics of the emotional burnout level according to the method suggested by V.V. Boiko. Results. During occupational activities healthcare workers are exposed to chemical, biological, physical work environment factors, the severity and intensity of the work process. Indices of the work process intensity are assigned to the leading hazardous occupational factor according to which the class of working conditions is determined as hazardous Class 1-3. PEBS, diseases of the musculoskeletal, circulatory, digestive and respiration systems are classified as work-related ones. An assessment of the possibility of the development of PEBS has shown 35% of the healthcare workers to consider working conditions to be related to PEBS. The dependence of the development of somatic diseases on the presence or absence of PEBS is revealed. Conclusion. The working conditions of healthcare workers are characterized by the impact of a complex of occupational factors, the leading of which is the work process intensity. Diseases of the musculoskeletal system, circulatory and respiration systems, psycho-emotional burnout syndrome are classified as work-related diseases with a high degree of conditionality. The criteria for evaluating the effectiveness of preventive measures are the reduction of general, work-related and occupational morbidity, the preservation of psychosomatic well-being, and the prevention of economic damage from temporary and permanent disability.

The a priori and a posteriori factors of occupational health risks among workers of the infectious service have been studied. It has been shown that workers with a high a priori risk (harmful Class 3.3) have minimal risk levels in terms of occupational morbidity (Ипр = 0,0005). The occupational morbidity of healthcare workers in the infectious disease service does not reflect the levels of actual risk for their health. On physical examination, only 4 % of workers were found to be practically healthy, most often diagnosed with diseases of the musculoskeletal system and connective tissue (19.8 %), as well as diseases of the circulatory system (18.8 %). Psychosocial effects leading to stress reactions with the development of chronic fatigue and occupational burnout syndrome (OBS) rank first among health problems of workers. The formed OBS was observed in 19.2 % of doctors and 29.2 % of nursing staff. The studies conducted indicate the probability of the prediction of the development of a high posterior risk to the health of workers of the infectious disease service.
