Perfil de morbimortalidade por COVID-19 e fatores associados à gravidade da doença em uma empresa de óleo e gás

Abstract

Workplaces are common settings for infectious disease outbreaks due to transmission between workers and their close contacts in their respective households and communities. In this way, work environments play an important role in the spread of the virus and, therefore, the analysis of how they are organized is crucial for the prevention of illness. Knowing the morbidity and mortality profile of workers from Covid- 19 is relevant to subsidize occupational health services, with public health guidelines for communicable diseases. Therefore, the objective of the research is analyzing the morbidity and mortality profile due to Covid-19 in an oil and gas company and factors associated with the severity of the disease. This is a cross-sectional, quantitative and analytical study, consisting of workers at an oil and gas company who had Covid-19 from June 2020 to June 2021. The source of information was the Program of Surveillance in Occupational Health of the company. The results showed that the total prevalence of cases was 21.7%. For workers in telework and on-site work, the prevalence was 20.7% and 23.3%, respectively. There was a predominance of women (19.7%; p=0,001), of white ethnicity/colour (64.7%; p=0,001), of higher level in the position (52.6%; p=0,001), of age group over 40 years (36.7%; p=0,001), of married (53.8%; p=0,009), of working at the company for a period that ranges from 7 to 10 years (17%; p=0,001), of administrative activity (68.5%; p=0,001) and symptomatic workers (8.8%; p=0,001) and deaths (0.9%; p=0,001) in telework compared to on-site work. Regarding the severity of the disease, of the total of 38.666 workers evaluated in the period, 8.394 were diagnosed with Covid-19 in the company studied. In the logistic regression analysis, it was found that being male (Adjusted OR 1.92; IC95% 1.26 – 2.93), aged 60 years or older (Adjusted OR 2.54; IC95% 1.30 – 4.99), increased odds of being hospitalized in a ward due to Covid-19 and being male (Adjusted OR 2.65; IC95% 1.53 – 4.61), being 60 years old or older (Adjusted OR 14.58; IC95% 8.13 – 26.16), increased the chances of severity due to Covid-19 leading to ICU admission or death. The results suggest that testing is important to contain the spread of the virus in the company's work environments, as it allowed workers, despite being asymptomatic, to be diagnosed with COVID-19 and removed from on-site work.
