Appropriate implementing of PPE
Generally, all health workers should implement appropriate personal protective equipment (PPE) regarding contact and droplet precautions based on recommendations by WHO [8]. For health workers in ICU, advanced protections are required during routine intensive care and airborne precautions are considered as airborne transmission may happen during aerosol-generating procedures. The implementation of PPE may be different by option in certain practices. In our experience, the most protective choices were made and the “zero” medical infection rate was treated as the top priority that all staff were equipped from head to toe. Compared to official recommendations, we selected some additional PPE during intensive care, such as an extra medical face mask outside the respirator, and both face shield and goggles (see Fig. 1). Additional PPE may increase the risk of sharp injuries and increase the difficulty of donning and doffing. To lower the incidence of adverse events, sequences of donning and doffing PPE were carefully developed based on the above selections through thorough group discussions and agreement was reached among the team.
