The Impact of Masking Habits on Voice in a Sub-population of Healthcare Workers

Abstract

Objective: To evaluate the impact of face masks on voice in a sub-population of healthcare workers, namely residents, medical students, and nurses, during the COVID-19 era. Materials and Methods: A cross-sectional study was conducted in a large tertiary care center where a 23-items web-based questionnaire was conveyed to sub-population of healthcare professionals, namely residents, medical students, and nurses. The questionnaire included demographic data, type, and duration of mask use. Voice outcome measures included the Voice Handicap Index (VHI)-10 questionnaire and the visual analogue scale for vocal effort and vocal fatigue. Results: A total of 178 participants answered the survey. One third had an abnormal score on the VHI-10 questionnaire, one third reported moderate to severe vocal fatigue, and 45% of the participants had moderate to severe vocal effort based on a visual analogue scale score. There was a significant association between the type of mask used and vocal fatigue (P = 0.044). No significant association was seen between the duration of mask used and the different voice outcome measures. Conclusion: Masking habits during the COVID-19 pandemic were associated with a high prevalence of vocal fatigue, effort and abnormal VHI-10 score among residents, medical students, and nurses. © 2022
