Discomfort in Use and Physical Disturbance of FFP2 Masks in a Group of Italian Doctors, Nurses and Nursing Aides during the COVID-19 Pandemic

Abstract

Face masks represent an effective COVID-19 mitigation strategy; this study investigated the quality in use of FFP2 masks in a group of 156 frontline HCWs recruited through a snowball procedure in northwest Italy. Participants filled out an online questionnaire (January 2022) on FFP2 sources of discomfort, physical disturbance at different anatomical points and suggestions for improvement. Most of the participants (69%) reported a feeling of protection and safety, but they also reported episodes of dyspnea (70%). The majority of glasses wearers (62%) reported fogging and displacement of their glasses. Humidity and heat were the main discomfort sources (39%), followed by elastic bands (32%). Physical disturbances were frequent and heavier on the ears, nose and cheekbones. Nursing aides and nurses perceived significantly more discomfort compared to doctors and nursing aides had the highest rate of physical disturbance. To address these issues, following participants’ suggestions, FFP2 masks should be redesigned to be more adjustable, with different sizes and softer fabrics. The investigation pointed out criticalities in the use of FFP2 masks related to different professional roles within the overall group of HCWs and stressed the need for an FFP2 human-centered design that accounts not only for physical needs but also for workload and task variability.
