Abstract
Objectives: Frontline healthcare workers (HCWs) are at high risk of SARS-CoV-2 infection. The aim of this study is to ensure risk-based protection when there is a lack of personal protective equipment (PPE).
Materials and methods: At the beginning of the pandemic, it was suggested that PPE were necessary to protect HCWs from COVID-19. However, given supply shortage, PPE had to be replaced in some situations. Three levels of protection were established depending on the risk level of exposure to SARS-CoV-2. Best practices were reviewed and analysed, and subsequently implemented in all hospitals in Catalonia. As the first COVID-19 wave progressed, we became more knowledgeable with the behaviour of the virus, so PPE procedure tables and algorithms were modified and adapted to the changing scenarios. After airborne transmission was demonstrated as the main route of the virus transmission, we emphasized new measures to ensure respiratory tract protection.
Results: Three general tables were established based on low, medium, and high risk of infection for HCWs. These three scenarios are a subgroup of the very high-risk category, according to OSHA’s pyramid of SARS-CoV-2 risk characterization. The most appropriate PPE for each task or job were identified and alternatives were given amid the shortage of PPE.
Conclusions: Specific PPE are required for the healthcare sector. Many studies on PPE are based on the characteristics of industrial jobs, and do not consider the specificities of the healthcare sector, which requires close and prolonged contact with patients.
