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 sub-sequently 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 trans-mission 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, ac-cording to OSHAs 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 (AU)
Objetivos: Los trabajadores sanitarios de primera línea tienen un alto riesgo de infección por SARS-CoV-2. El objetivo de este estudio es garantizar la protección según el nivel riesgo cuando falta el equipo de protección personal (EPI).Métodos: Al comienzo de la pandemia, se sugirió que el EPI era necesario para proteger a los trabajadores de la salud del COVID-19; pero dada la escasez, el EPI tuvo que ser reem-plazado en algunos escenarios. Se establecieron tres niveles de protección dependiendo del nivel de riesgo de exposición al SARS-CoV-2. Se analizaron las mejores prácticas para su posterior implantación en todos los hospitales de Cataluña. A medida que avanzaba la primera ola, nos familiarizamos mejor con el comportamiento del virus y los procedimien-tos en formato de tablas se modificaron y adaptaron a los nuevos escenarios. Se produjo un punto de inflexión después de que se confirmara que la mayoría de las infecciones se debían a la transmisión por vía aérea. Este avance mostró la importancia de identificar nue-vas medidas que pudieran garantizar la protección de las vías respiratorias.Resultados: Se han establecido tres tablas generales con según el riesgo bajo, medio y alto de contagio de los trabajadores de la salud. Estos tres escenarios son un subgrupo de la categoría de riesgo muy alto, de acuerdo con la pirámide de caracterización del riesgo de SARS-CoV-2 de OSHA. Se ha identificado el EPI más adecuado para cada tarea o trabajo y se han dado alternativas ante la escasez de EPI. Conclusiones: Se requieren EPI específicos para el sector sanitario. Muchos estudios reali-zados sobre EPI se basan en las características de los trabajos industriales y no consideran las especificidades del sector sanitario, que requiere un contacto cercano y prolongado con los pacientes (AU)

BACKGROUND AND OBJECTIVE: In the COVID-19 pandemic, the demand of masks has been increased by health professionals and the general population. In this context, it is necessary to summarize the features and indications of the different types of masks. MATERIAL AND METHODS: To consult and to compile the different recommendations disseminated by prestigious institutions such as the World Health Organization, the European Center for Disease Prevention, the Center for Evidence-Based Medicine, or the Ministry of Health of the Government of Spain has been reviewed. RESULTS: The institutions consulted recommend reserving FFP respirators for healthcare workers, especially when carrying out aerosol-generating procedures (AGPs) (minimum FFP2 protection) and consider some reutilization systems during times of scarcity. The use of surgical masks is recommended to professionals who do not perform AGPs and to the symptomatic population but exist variations in its indications intended for the general healthy population. CONCLUSION: In the context of shortage of personal protective equipment due to the COVID-19 pandemic, a prioritization and rationalization of the use of each type of mask should be established according to the user and the activity performed.
