Analysis of occupational risk factors causing diseases of the circulatory system in medical workers: Literature review

“…Occupational activities performed by medical workers involve substantial intellectual loads, elevated requirements to capacity of operative and longterm memory as well as attention; some specialists (doctors and paramedics in emergency aid teams, surgeons) often have to work under extreme conditions in case of an emergency and it requires developing a set of preventive activities aimed at preserving their health and maintaining necessary occupational skills [2,[17][18][19][20][21][22][23] 1 . CSDs prevalence among medical workers is different in various occupational groups (from 39.6 to 55.8 cases per 100 patients); however, they occupy the first rank place in the overall morbidity (25.0-27.6 %) for doctors of practically all specialties and the second or third rank place for nurses and paramedics [24]. Bearing in mind that medical workers are exposed to a lot of variable adverse occupational factors at their workplaces and CSDs prevalence is high among them, a lot of studies have concentrated on assessment of working conditions with a focus being on risk factors of cardiovascular diseases and substantiating suggestions on how to prevent them [7-9, 11-16, 25-31].…”

“…Examination of working conditions and workers' health is accomplished according to valid regulatory documents. An evidence base for occupational risk assessment is results obtained in research works concentrating on hygienic assessment of working conditions and occupational activities as adverse factors that can cause damage to health of medical workers with various specialties employed at various healthcare organizations [1,2,[17][18][19][20][21][22][23][24][25][26][27]32-41] 1, 2 .…”

“…Complex studies with focus on health of medical workers in various regions in the country and our own long-term research revealed that CSDs prevalence and their specific weight in the structure of overall morbidity were higher among medical workers than among workers employed in various industries. Profound medical examinations accomplished in various public healthcare organizations showed that on average 48.3 cases of cardiovascular diseases were detected per 100 examined doctors and 37.4 cases per 100 examined nurses and paramedics [18,24]. Their specific weight varies from 32.8 to 48.8 % in overall morbidity [24].…”

“…Profound medical examinations accomplished in various public healthcare organizations showed that on average 48.3 cases of cardiovascular diseases were detected per 100 examined doctors and 37.4 cases per 100 examined nurses and paramedics [18,24]. Their specific weight varies from 32.8 to 48.8 % in overall morbidity [24]. These rates are substantially higher than among workers employed at various industrial enterprises as well as among population in general.…”

“…Some researchers [18,24] note that CSDs account for 48.3 % cases in morbidity among doctors and 37.4 % cases among nurses and paramedics. In this case attributive risk amounts to 30.3 cases per 100 people for doctors and to 19.4 cases for nurses and paramedics; relative risks reach 2.6 for doctors and 2.0 for nurses and paramedics.…”
