With the introduction of large-scale medical examinations in Russia, the process of reorienting the activities of medical organizations providing primary health care on an outpatient basis to the prevention of chronic non-communicable diseases, in particular, cardiovascular diseases, is taking place. However, at present, dispensary observation coverage cannot be considered high, which is due to shortcomings in the organization of the accounting and observation process, lack of time during the period of medical appointment, inaccurate determination of the risk of adverse outcomes, and low patient compliance. In this regard, scientific research aimed at eliminating the "bottlenecks" of dispensary observation with the help of information technology seems to be timely and relevant. The aim of the study: Substantiate proposals for improving the dispensary observation of employees of a housing and communal services enterprise with hypertension and evaluate the effectiveness of the proposed solutions using information technologies. Material and methods: The research was carried out on the basis of a departmental outpatient clinic - the Medical and Sanitary Department of the State Unitary Enterprise "Vodokanal of St. Petersburg". Continuous retrospective monitoring of the incidence and seeking medical care in 4634 people in 2015-2020, who were employees of the enterprise. When studying morbidity according to the data of periodic medical examinations and morbidity with temporary disability (TD), extensive indicators were calculated indicating the structure of morbidity and intensive indicators characterizing the prevalence of the pathological process (number of diagnoses per 100 examined). When forming risk groups for morbidity with temporary disability (TD), a neural network model was used. Results of the study: Based on analysis of the health status of individual employees of a large housing and communal services enterprise for 2015-2017, the forecast of the incidence of the cardiovascular system, a regulation on the organization of medical and preventive measures for employees of SUE "Vodokanal of St. Petersburg" was developed and implemented in 2018-2019 (hereinafter – Enterprise) with hypertension. The analysis of morbidity with TD before and after the introduction of the regulation showed a statistically significant decrease from 43.6% to 31.4% of cases of diseases characterized by high arterial blood pressure, and from 9.8% to 6.5% of cases of diseases of the circulatory system in general. Enterprise. The number of suspensions from driving for health reasons based on the results of pre-trip medical examinations decreased by 36.8% from 6.8 to 4.3 people per day. Conclusion: Study of the structure and dynamics of individual morbidity and medical support for employees of the Enterprise made it possible to determine the directions of managerial influences to reduce morbidity: the need to introduce preventive measures aimed at reducing the prevalence of hypertension; the need to determine a group of persons at risk of developing diseases of the circulatory system and the need to organize a uniform work of the occupational medicine service of the medical unit.
