BACKGROUND: Coronavirus disease 2019 (COVID-19) is an emerging infectious disease of pandemic proportions. Healthcare workers in Singapore working in high-risk areas were mandated to wear personal protective equipment (PPE) such as N95 face mask and protective eyewear while attending to patients. OBJECTIVES: We sought to determine the risk factors associated with the development of de novo PPE-associated headaches as well as the perceived impact of these headaches on their personal health and work performance. The impact of COVID-19 on pre-existing headache disorders was also investigated. METHODS: This is a cross-sectional study among healthcare workers at our tertiary institution who were working in high-risk hospital areas during COVID-19. All respondents completed a self-administered questionnaire. RESULTS: A total of 158 healthcare workers participated in the study. Majority 126/158 (77.8%) were aged 21-35 years. Participants included nurses 102/158 (64.6%), doctors 51/158 (32.3%), and paramedical staff 5/158 (3.2%). Pre-existing primary headache diagnosis was present in about a third 46/158 (29.1%) of respondents. Those based at the emergency department had higher average daily duration of combined PPE exposure compared to those working in isolation wards [7.0 (SD 2.2) vs 5.2 (SD 2.4) hours, P 4 hours per day (OR 3.91, 95% CI 1.35-11.31; P = .012) were independently associated with de novo PPE-associated headaches. Since COVID-19 outbreak, 42/46 (91.3%) of respondents with pre-existing headache diagnosis either "agreed" or "strongly agreed" that the increased PPE usage had affected the control of their background headaches, which affected their level of work performance. CONCLUSION: Most healthcare workers develop de novo PPE-associated headaches or exacerbation of their pre-existing headache disorders.
