Impact of SARS-CoV-2 Virus (COVID-19) Preventative Measures on Communication: A Scoping Review

Abstract

IntroductionFace coverings and distancing as preventative measures against the spread of the Coronavirus disease 2019 may impact communication in several ways that may disproportionately affect people with hearing loss. A scoping review was conducted to examine existing literature on the impact of preventative measures on communication and to characterize the clinical implications.MethodA systematic search of three electronic databases (Scopus, PubMed, CINAHL) was conducted yielding 2,158 articles. After removing duplicates and screening to determine inclusion eligibility, key data were extracted from the 50 included articles. Findings are reported following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) Extension for Scoping Reviews, including the PRISMA-ScR checklist.ResultsStudies fell into three categories: Studies addressing the impacts of personal protective equipment (PPE) and/or distancing on communication in healthcare contexts (n = 20); studies examining the impact of preventative measures on communication in everyday life (n = 13), and studies measuring the impact of face coverings on speech using acoustic and/or behavioral measures (n = 29). The review revealed that masks disrupt verbal and non-verbal communication, as well as emotional and social wellbeing and they impact people with hearing loss more than those without. These findings are presumably because opaque masks attenuate sound at frequencies above 1 kHz, and conceal the mouth and lips making lipreading impossible, and limit visibility of facial expressions. While surgical masks cause relatively little sound attenuation, transparent masks and face shields are highly attenuating. However, they are preferred by people with hearing loss because they give access to visual cues.ConclusionFace coverings and social distancing has detrimental effects that extend well beyond verbal and non-verbal communication, by affecting wellbeing and quality of life. As these measures will likely be part of everyday life for the foreseeable future, we propose that it is necessary to support effective communication, especially in healthcare settings and for people with hearing loss.

The COVID-19 burnout scale: Development and initial validation

“…Moreover, evidence shows that the adherence of individuals to COVID-19 preventive measures (e.g. face covering and social distancing) disrupts verbal and non-verbal communication and affects negatively wellbeing and quality of life (Oosthuizen et al, 2022).…”

The impact of face coverings on audio-visual contributions to communication with conversational speech

“…They are also widely used to reduce human exposure to particulates and other noxious substances. Widespread use of face coverings during the COVID-19 pandemic brought attention to the negative impacts of face coverings on communication (reviewed in Oosthuizen et al, 2022 ). By restricting access to auditory and visual cues conveying both information and emotion, face coverings can disrupt effective communication.…”

Assessing the impact of COVID-19 pandemic on the health of residents and the healthcare system in Alberta, Canada: an observational study—The Alberta POST-COVID Follow-up Study

“… 1 Despite global efforts to contain the infection with preventive measures and the success of rapid vaccine development, the COVID-19 pandemic has continued to have a significant impact on society and the healthcare system. 2 3 It has been established that COVID-19 can result in a multiorgan disease with a wide spectrum of disparate clinical manifestations, ranging from completely asymptomatic infection to a cluster of pneumonia, multiorgan failure and death, which is associated with direct SARS-CoV-2 attacks and indirect systemic inflammatory responses in multiorgan tissues such as the lung, the heart, kidneys, eyes and endothelium. 4 Even after recovering from the acute COVID-19 infection, growing reports have suggested residual effects of COVID-19, termed ‘long COVID-19’, on both the non-hospitalised and hospitalised COVID-19 survivors.…”
