Characterization and assessment of exposure risks of healthcare personnel during the COVID-19 pandemic.

ABSTRACT

Introduction: Healthcare personnel have the right to decent, healthy, and safe working conditions during COVID-19. Despite our best efforts to safeguard them against SARS-CoV-2 infection, a substantially large number of healthcare personnel fell ill and succumbed to COVID-19. This study aimed to characterize the SARS-CoV-2 exposures among healthcare personnel and determine the risk level of those events, thereby identifying and focusing on the key areas that influence workplace safety. Materials and Methods: A pre-tested questionnaire was used to collect data from healthcare personnel on the type of exposure, place, and use of preventive measures, along with demographic and occupational data. Exposure events were categorized into low, moderate, and high-risk by using a risk categorization protocol. Results: Doctors were primarily found to be involved in the aerosol-generating procedure, which had 94 times higher odds (95% CI 43.9926-201.17) for high-risk exposures than other activities. In contrast, nurses were more likely to experience close-contact exposures (OR 2.77, 95% CI 1.44-5.33). Both critical care units and operation theaters were identified to have higher odds (OR 2.34, 95% CI 1.33-4.23 and OR 2.31; 95% CI 0.99-5.42, respectively) than the wards for high-risk exposures. Use of personal protective equipment was poor, with breaches reported in 10.2% of all exposure events. The lacunae in practice were addressed by repeated training and counseling and by ensuring the adequacy of resources in required areas. Conclusions: The assessment was beneficial for safeguarding healthcare personnel and assuring a safer workplace during the early phase of the COVID-19 pandemic.
