Improvement of criteria and methods for assessing the functional state and factors of the labor process based on a personalized approach

Introduction. Prolonged exposure to the factors of nervous and stressful mental labor forms unfavorable stress conditions of physiological systems, increasing the risk of developing occupational diseases, including pathology of the cardiovascular system. Numerous studies devoted to the study of the functional state have not revealed a sufficiently unified approach to its assessment, which determines the relevance of this work. The study aims to develop criteria and methods for assessing the functional state and factors of the labor process of workers in neuropsychiatric labor, taking into account people of different age groups to preserve health and labor potential. Materials and methods. The researchers assessed the functional state according to pre-shift medical control data on professional groups of ground transport drivers and employees of locomotive crews of Russian Railways, which were selected and analyzed based on gender and age differences. According to the indicators of heart rate, blood pressure, scientists calculated the production parameters of hemodynamics (peripheral resistance, minute volume), indices of the cardiovascular system (Index of Functional Changes, Myznikov index, Kerdo vegetative index), which revealed a close correlation with age. The authors carried out statistical processing of the obtained data using IBM SPSS Statistics 26 software. Results. Based on the database of pre-trip medical examinations, specialists have developed a model for the step-by-step geometric construction of nonlinear fluctuations of the cardiovascular system, which allows us to assess and predict the functional state of a person, the degree of disturbance of vegetative balance, and the risks of developing pathology in the cardiovascular system. Based on the parameters of the digital profiles of employees, taking into account gender and age characteristics, new algorithms for assessing the functional state for monitoring the working capacity of employees were introduced into the existing digital information system of the Institute's Medical Information System. Conclusion. The researchers have developed a criterion apparatus and a set of methods for assessing the indicators of the functional state of the body (according to the indicators of the cardiovascular system) in conditions of neuro-emotional labor activity, taking into account the influence of factors of tension and severity of the labor process on the health of workers (risks of arterial hypertension) of various gender and age groups in modern conditions. Based on the results of comprehensive studies of workers in neuropsychiatric mental labor, the standards of work intensity were improved, and the authors proposed a new version of the indicator "Work with information load and creative content (% of shift time)". Limitations. There are limitations due to the peculiarities of collecting (obtaining) physiological data during pre-trip medical examinations. Ethics. The study was approved by the local Ethical Committee of Izmerov Research Institute of Occupational Health (protocol No. 1 of February 16, 2022).
