Assessing the quality of life of head and neck healthcare workers during the COVID-19 pandemic-A self-reportedglobal cross-sectional questionnaire study by the International Federation of Head and Neck Oncologic Societies

BACKGROUND: Considering the pandemic's mode of transmission, the impact on quality of life (QOL) is likely to be exaggerated among healthcare workers (HCWs) who treat head and neck diseases (hHCWs). METHODS: A cross-sectional self-reported QOL assessment was undertaken between July and September 2020 using the World Health Organization Quality of Life instrument sent out to hHCWs.
