Results of a national web-based survey on the SARS-CoV-2 infectious state of otorhinolaryngologists in Germany

[The first year of the SARS-CoV-2 pandemic-impact on otorhinolaryngology]

BACKGROUND

The first year of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has already affected our public health care system to an enormous extent and will continue to do so in the future. Otorhinolaryngologists (ORLs) are suspected to be at high risk of infection, due to the high viral load in the mucosa of the upper airways. The current review evaluates the impact of the pandemic on ORLs' activities and assesses the risk infection.

METHODS

A selective literature research was conducted using relevant English and German terms for ORL, SARS-CoV‑2, risk, and infection at PubMed, medRxiv, and bioRxiv, as well as in the Deutsches Ärzteblatt and on the websites of the Robert Koch Institute and the Johns Hopkins University.

RESULTS

Protection recommendations for ORL include general hygiene measures and wearing KN95 masks for routine professional activities. When in contact with coronavirus disease 2019 (COVID-19) patients, it is recommended to extend the personal protective equipment by eye protection, gloves, cap, and gown. International otorhinolaryngology societies have released guidelines for procedures (e.g., tracheostomy, sinus surgery), propagating personal protection for the surgical team and reduction of aerosols. Testing for SARS-CoV‑2 in patients and medical staff can contribute to reducing the risk of infection. Vaccination would provide some additional protection for ORLs and other health care professionals with increased exposure to aerosols. There is increasing evidence that ORLs are at a high risk of contracting SARS-CoV‑2.

CONCLUSION

Consequent personal protection, frequent testing of patients and health care professionals, and the promised SARS-CoV‑2 vaccinations may provide adequate protection for highly exposed persons.

Follow-up of a national web-based survey on the SARS-CoV-2 infectious state of otorhinolaryngologists in Germany

Purpose

The SARS-CoV‑2 pandemic has affected the health and practice of otorhinolaryngologists (ORLs) for over 1 year. Follow-up data of a national survey with German ORLs were evaluated regarding differences between the two waves of the pandemic.

Methods

As in the initial survey, German ORLs were addressed via e‑mail through the German Society of ORL, Head and Neck Surgery and the German ENT Association. All ORLs afflicted with SARS-CoV‑2 were invited to participate in a web-based survey. General data on infections and concomitant parameters were evaluated.

Results

Since the start of the pandemic, 129 ORLs reported testing positive for SARS-CoV‑2 in Germany. The ORLs infected during the first wave had a relative risk (RR) of 4.07 (95% CI: 3.20; 5.19) of contracting SARS-CoV‑2. During the second wave, the RR decreased to 0.35 (95% CI: 0.28; 0.45). The availability of personal protective equipment (PPE) increased from the first to the second wave along with an increased perception of protection in the professional environment. The source of infection shifted from infections via medical staff during the first wave to patients and household exposure during the second wave. Regular medical practice was resumed by clinicians and general practitioners in the second wave. Nevertheless, a proportionally lower infection rate was observed compared with the German population as a whole.

Conclusion

The data reflect a unique long-term survey of ORLs during the pandemic. Differences in the source of infection were seen between the first and second wave, confirming the need for appropriate PPE for medical professionals working in high-risk environments. Further strategies to reduce the risk of infection include consistent testing for SARS-CoV‑2 in healthcare professionals, patients, and the general public as well as vaccination of high-risk medical groups.

[Effects of the SARS-CoV‑2 pandemic on the otolaryngology university hospitals in the field of research, student teaching and specialist training]

Hintergrund

Ab Frühjahr 2020 kam es zur weltweiten Verbreitung von SARS-CoV‑2 mit der heute als erste Welle der Pandemie bezeichneten Phase ab März 2020. Diese resultierte an vielen Kliniken in Umstrukturierungen und Ressourcenverschiebungen. Ziel unserer Arbeit war die Erfassung der Auswirkungen der Pandemie auf die universitäre Hals-Nasen-Ohren(HNO)-Heilkunde für die Forschung, Lehre und Weiterbildung.

Material und Methoden

Die Direktorinnen und Direktoren der 39 Universitäts-HNO-Kliniken in Deutschland wurden mithilfe einer strukturierten Online-Befragung zu den Auswirkungen der Pandemie im Zeitraum von März bis April 2020 auf die Forschung, Lehre und die Weiterbildung befragt.

Ergebnisse

Alle 39 Direktorinnen und Direktoren beteiligten sich an der Umfrage. Hiervon gaben 74,4 % (29/39) an, dass es zu einer Verschlechterung ihrer Forschungstätigkeit infolge der Pandemie gekommen sei. Von 61,5 % (24/39) wurde berichtet, dass pandemiebezogene Forschungsaspekte aufgegriffen wurden. Von allen Kliniken wurde eine Einschränkung der Präsenzlehre berichtet und 97,5 % (38/39) führten neue digitale Lehrformate ein. Im Beobachtungszeitraum sahen 74,4 % der Klinikdirektoren die Weiterbildung der Assistenten nicht gefährdet.

Schlussfolgerung

Die Ergebnisse geben einen Einblick in die heterogenen Auswirkungen der Pandemie. Die kurzfristige Bearbeitung pandemiebezogener Forschungsthemen und die Einführung innovativer digitaler Konzepte für die studentische Lehre belegt eindrücklich das große innovative Potenzial und die schnelle Reaktionsfähigkeit der HNO-Universitätskliniken, um auch während der Pandemie ihre Aufgaben in der Forschung, Lehre und Weiterbildung bestmöglich zu erfüllen.
