Canadian dental hygienists' experiences and perceptions of regulatory guidelines during the COVID-19 pandemic: a qualitative descriptive analysis.

BACKGROUND: In Spring of 2020, due to the COVID-19 pandemic, Canadian provincial dental hygiene regulatory bodies implemented new practice guidelines. Reports of stress, anxiety and conflict experienced by dental hygienists have been linked to miscommunication between oral health regulators at this time. Limited data exists on the perceptions and experiences of dental hygienists navigating new guidelines for dental hygiene care during the pandemic. Therefore, the objective of our study was to explore via descriptive thematic analysis how dental hygienists experienced and perceived: i) dental hygiene practice during the COVID-19 pandemic, and ii) their regulatory body's COVID-19 guidelines. METHODS: Participants were identified through provincial dental hygiene licensing bodies. Online bi-monthly questionnaires were administered to participants (n = 876) from December 2021 to January 2022. Two open-ended questions were asked in the questionnaire. A qualitative descriptive thematic analysis was applied to these two questions. RESULTS: Major themes at baseline relayed challenges related to workplace compliance, patient treatment and communication of practice protocols. Across responses, hygienists confirmed conflicting messaging from regulators and guideline interpretations as stressors impacting their professional practice and satisfaction within the profession. Participant responses at endpoint cited increased satisfaction with regulatory guidelines as the pandemic evolved, yet inconsistencies in regulators' messaging was noted as a prevailing issue. CONCLUSION: Inconsistent guideline messaging reflects an increased need for collaboration amongst oral health care regulators to streamline protocols for practice and reduce interprofessional conflict in pandemic circumstances. A national unified approach is warranted in establishing guidelines for dental hygiene practice in Canada.

COVID-19 incidence and vaccination rates among Canadian dental hygienists.

Background: Oral health care settings potentially carry a high risk of cross-infection due to close contact and aerosol-generating procedures. There is limited evidence of the impact of COVID-19 among dental hygienists. This longitudinal study aimed to 1) estimate COVID-19 incidence rates among Canadian dental hygienists over a 1-year period; and 2) estimate vaccination rates among Canadian dental hygienists. Methods: A prospective cohort study design was used to collect self-reported COVID-19 status from 876 registered dental hygienists across Canada via an online baseline survey and then 6 follow-up questionnaires delivered between December 2020 and January 2022. Bayesian Poisson and binomial models were used to estimate the incidence rate and cumulative incidence of self-reported COVID-19. Results: The estimated cumulative incidence of COVID-19 in dental hygienists in Canada from December 2020 to January 2022 was 2.39% (95% CrI, 1.49%-3.50%), while the estimated cumulative incidence of COVID-19 in corresponding Canadian provinces was 5.12% (95% CrI, 5.12%-5.13%) during the same period. At last follow-up, 89.4% of participants self-reported that they had received at least 1 dose of a COVID-19 vaccine. Conclusion: The low infection rate observed among Canadian dental hygienists between December 2020 and January 2022 is reassuring to the dental hygiene and general community.

Contexte : Les milieux de soins buccodentaires présentent potentiellement un risque élevé d'infections croisées en raison des contacts étroits et des procédures qui produisent des aérosols. Il y a peu de preuves de l'effet de la COVID-19 chez les hygiénistes dentaires. La présente étude longitudinale visait à 1) estimer les taux d'incidence de la COVID-19 chez les hygiénistes dentaires canadiens sur une période d'un an; et 2) estimer les taux de vaccination chez les hygiénistes dentaires canadiens. Méthodologie : Une méthodologie prospective des cohortes a été utilisée pour recueillir le statut de COVID-19 autodéclaré de 876 hygiénistes dentaires autorisés au Canada par l'intermédiaire d'une enquête initiale en ligne, puis de 6 questionnaires de suivi, distribués entre décembre 2020 et janvier 2022. Des modèles bayésiens de Poisson et binomiaux ont été utilisés pour estimer le taux d'incidence et l'incidence cumulative de la COVID-19 autodéclarée. Résultats : L'incidence cumulative estimée de la COVID-19 chez les hygiénistes dentaires au Canada entre décembre 2020 et janvier 2022 était de 2,39 % (intervalle de crédibilité à 95 %, 1,49 % ­ 3,50 %), alors que l'incidence cumulative estimée de la COVID-19 dans les provinces canadiennes correspondantes était de 5,12 % (intervalle de crédibilité à 95 %, 5,12 % ­ 5,13 %) au cours de la même période. Lors du dernier suivi, 89,4 % des participants ont déclaré avoir reçu au moins une dose du vaccin contre la COVID-19. Conclusion : Le faible taux d'infection constaté chez les hygiénistes dentaires canadiens entre décembre 2020 et janvier 2022 est rassurant pour la communauté d'hygiène dentaire et la communauté générale.

The incidence of COVID-19 among dentists practicing in the community in Canada: A prospective cohort study over a 6-month period.

BACKGROUND: Oral health care settings carry a potentially high risk of causing cross-infection between dentists and patients and among dental staff members due to close contact and use of aerosol-generating procedures. The authors aimed to estimate COVID-19 incidence rates among Canadian dentists over a 6-month period. METHODS: The authors conducted a prospective cohort study of 644 licensed dentists across Canada from July 29, 2020, through February 12, 2021. An online questionnaire, adapted from the World Health Organization's Unity Studies protocols for assessment of COVID-19 risk among health care workers, was used to collect data on self-reported severe acute respiratory syndrome coronavirus 2 infections every 4 weeks. A bayesian Poisson model was used to estimate the incidence rate and corresponding 95% credible intervals (CIs). RESULTS: Median age of participants was 47 years; most participants were women (56.4%) and general practitioners (90.8%). Median follow-up time was 188 days. Six participants reported COVID-19 infections during the study period, giving an incidence rate of 5.10 per 100,000 person-days (95% CI, 1.86 to 9.91 per 100,000 person-days). The incidence proportion was estimated to be 1,084 per 100,000 dentists (95% CI, 438 to 2,011 per 100,000 dentists) and 1,864 per 100,000 people (95% CI, 1,859 to 1,868 per 100,000 people) in the Canadian population during the same period. CONCLUSIONS: The low infection rate observed among Canadian dentists from July 29, 2020, through February 12, 2021, should be reassuring to the dental and general community. PRACTICAL IMPLICATIONS: Although the infection rates were low among Canadian dentists, it is important to continue to collect disease surveillance data.
