Live Scoping Review of N95 and Surgical Facemask Decontamination and Reuse: A Scoping Review Protocol
During the COVID-19 pandemic, a shortage of personal protective equipment (PPE), namely surgical masks, N95 masks, and gowns, has been experienced by some hospitals and could be expected in others due to a rapidly increased need. The Centres for Disease Control and Prevention (CDC) specifically recommends N95 filtering facepiece respirators (FFRs) for healthcare workers who are interacting with patients with COVID-19 under aerosol precautions, and when performing aerosol generating medical procedures. In contrast, surgical masks have much broader use and are recommended for use by health care providers to protect against the risk of droplet transmission in inpatient healthcare settings and outpatient settings (e.g. COVID-19 assessment centres, long-term care facilities, and community care settings). One potential method of addressing the shortage and ensuring adequate protection for health care workers in accordance with the above recommendations would be to decontaminate and reuse N95 FFRs and surgical masks. Our group recently conducted a series of systematic reviews to synthesize the existing literature on N95 and surgical mask decontamination. However, literature in this area is rapidly evolving and these systematic reviews will require updates in order to provide clinicians, hospital administrators, and public health officials with the most up-to-date and comprehensive information available. The purpose of this living scoping review is to identify all original research on N95 and surgical mask decontamination and reuse, and to build an open-access database of the existing literature.
