Introduction. Occupational neurosensory hearing loss is one of the most common occupational diseases. So far, there have been no studies in the scientific literature devoted to a retrospective analysis of professional conditions and conditions of medical care organization in case this pathology is detected in workers served by the system of health care institutions of FMBA of Russia.Materials and methods The study used data from the "Industry register of persons with occupational diseases", accounting documents and regulations that allow an analysis of working conditions and medical care.Results The rate of neurosensory hearing loss was 31.3 % in the structure of occupational diseases among employees of enterprises and organizations served by FMBA health care institutions of Russia in 2010-2020. The frequency of continuous use of anti-noise personal protective equipment decreased from 77.8 % (2010–2015) to 75.4 % (2016–2020). Occupational neurosensory hearing loss was diagnosed in 79.4 % of workers based on periodic medical examinations and in 20.6 % of workers based on self-referrals. The decision to refer an employee for determination of the degree of disability was made in 16.5 % of cases.Discussion On the basis of the scientific literature and the results of our study, a proposal to take into account not only physical, but also chemical occupational hazards that aggravate the impact of industrial noise on employee health, as well as the anamnesis of tobacco smoking, cardiovascular disease, diabetes mellitus and atherosclerosis.Conclusion The risk group for occupational neurosensory hearing loss is men over 50 years of age. The duration of formation of this pathology is 34,1 ± 1,1 years at the PS level of 90,6 ± 1,0 dB. The importance of optimal organization of periodic medical examinations and the need to control the use of anti-noise personal protective equipment in the workplace is noted.
For persons with occupational diseases who worked at enterprises and organizations served by medical institutions of the FMBA of the Russian Federation, it is relevant to assess their health, taking into account the impact of harmful chemical production factors that have become the causes of their occupational diseases. About 2/3 of cases of occupational diseases caused by chemical hazards are organophosphorus compounds (pesticides), beryllium and its compounds. Of the diseases of non-professional genesis, this group of persons has the highest prevalence of diseases of the circulatory system, musculoskeletal system, digestive and respiratory organs. Of the diseases of the circulatory system, the most commonly diagnosed diseases are those characterized by high blood pressure and coronary heart disease. The structure of diseases of the digestive system is dominated by diseases of the esophagus, stomach and duodenum, diseases of the gall bladder, biliary tract and pancreas. Dorsopathies are the most common within the musculoskeletal disorders; chronic diseases of the upper and lower respiratory tract – within the respiratory diseases.
Purpose: Analysis of the prevalence of diseases of non-professional genesis in individuals with intake of radionuclides through damaged skin and served by health care institutions of the Federal Medical and Biological Agency of Russia. Material and methods: The database of the “Industry register of persons with occupational diseases” includes the health indicators of individuals with intake of radionuclides through damaged skin and a population of 185 patients aged 68.9 ± 1.0 years for 2014 (166 men aged 68.3 ± 1.0 years and 19 women aged 74.0 ± 3.4 years). The coding of diseases of non-professional genesis was carried out according to the International Statistical Classification of Diseases and Problems Related to Health (ICD-10). Student’s criterion was used as a criterion of statistical validity (p < 0.05). To assess the health of persons counted in the register, the prevalence rate of diseases of non-professional genesis, calculated for 1000 patients with occupational diseases, was used. An intensive indicator error was calculated ( ± m 95 %). Results: The prevalence of non-occupational diseases is 1637.8 ± 94.1 (men 1614.5 ± 98.6, women 1842.1 ± 311.4; p > 0.05). Disorders of the musculoskeletal system occupy the first place – 340.5 ± 34.8; 20.8 % (men 313.3 ± 36.0; 19.4 %, women 578.9 ± 174.6; 31.4 %; p > 0.05). Of these, dorsopathies accounted for 286.5 ± 33.1; 84.1 % (men 265.1 ± 34.3; 84.6 %, women 473.7 ± 114.6; 81.8 %; p > 0.05). Diseases of the digestive organs are 270.3 ± 32.7; 16.5 %. The highest rates in persons with diseases of the esophagus, stomach and duodenum 205.4 ± 29.7; 76.0 % (men 210.8 ± 31.7; 76.1 %, women 157.9 ± 83.7; 75.0 %; p > 0.05). The third ranking place is divided by diseases of the eye and its adnexa 200.0 ± 29.4; 12.2 % (men 192.8 ± 30.6; 11.9 %, women, 263.2 ± 101.0; 14.3 %; p > 0.05) and circulatory system diseases 200.0 ± 29,4; 12.2 % (men 174.7 ± 29.5; 10.8 %, women 421.1 ± 113.3; 22.9 %; p > 0.05). In the structure of diseases of non-professional genesis, the diseases of the first four ranking places, including respiratory diseases, make up 73.6 % (men 72.4 %, women 82.9 %). Conclusion: Among the diseases in persons with the intake of radionuclides through damaged skin are the most common disorders of the musculoskeletal system, diseases of the digestive system, diseases of the eye and its appendage apparatus. In terms of frequency, they are inferior to diseases of the circulatory system and respiratory organs. As one of the solutions to the problem of registration in persons with signs of contamination of radionuclides of damaged skin in the framework of ICD-10, it is proposed to introduce code S61.2 as “Open wounds of wrist and hand with intake of radionuclides”.
