ABSTRACT
BackgroundConsistent guidelines on respiratory protection for healthcare professionals combined with improved global supply chains are critical to prevent COVID-19. We analysed the guidelines published by national and international societies/organizations on facemasks and respirators to prevent COVID-19 in healthcare settings. MethodsFrom the 1st January to the 2nd April 2020, guidelines published in four countries (France, Germany, United States, United Kingdom), and two international organizations (US and European Centre for Diseases Control, and World Health Organization) were reviewed to analyse the mask and respirators recommended for healthcare settings during the COVID-19 outbreak. The aerosol generating procedures (AGP) definitions and the strategy recommended for optimizing supplies and overcoming shortages were collected. FindingsThe recommendation of respirator was universally recommended for AGP across countries, although the type of respirators and what constituted an AGP was variable. Some guidance maintained the use of N95/99 for all contact with confirmed COVID-19 cases (i.e. Germany) whereas others, recommended a surgical mask (i.e. WHO, UK, France). Most guidelines were published in March with either downgraded (US and European CDC), relatively stable (WHO, Germany, and UK), or a mixing of high and low level equipment (France). The strategies to overcome shortage of respiratory protection equipment were based on minimizing the need and rationalizing the use, but also prolonging their use, reusing them after cleaning/sterilization, or using cloth masks. InterpretationsIn a crisis context, stable and consistent guidelines clearly detailing the respiratory protection type, and their indications, may prevent the confusion and anxiety among frontline staff, and avoid shortage.
