This study was a retrospective study purposed to describe 1) the incidence of occupational COVID-19 infections in healthcare workers and 2) the factors associated with occupational COVID-19 infections.
Secondary data were collected from October 1, 2021 to September 30, 2022, involving a total of 663 healthcare workers. The data were collected by using data recording forms for COVID-19 post-exposure risk assessment and medical records. Descriptive analysis presented as percentages and frequencies, while factors related to occupational COVID-19 infections were analyzed by using multivariate logistic regression
statistics. The result revealed an incidence of 16.6% for occupational COVID-19 infections. The highest infection risk was observed in the supporting department, with an odds ratio of 3.5 (p-value<0.05). Healthcare workers using inappropriate personal protective equipment had a 3.8 times higher risk of infection compared to those with appropriate personal protective equipment (p-value<0.05). Multivariate logistic regression analysis identified two significant factors associated with occupational COVID-19 infections. The highest infection risk was observed in the supporting department, with an adjusted odds ratio of 3.2
(p-value<0.05). Healthcare workers using inappropriate personal protective equipment had a higher risk of infection than those with appropriate personal protective equipment, with an adjusted odds ratio of 3.5
(p-value<0.05). According to this study, it is recommended to enhance prevention measure and provide intensive infectious control training, especially for the supporting department.
