[COVID-19 and endoscopy services]. / COVID-19 und Endoskopieeinheiten: Erfahrungen und Empfehlungen nach 2 Jahren Pandemie.

ABSTRACT

In 2020, the coronavirus pandemic initially led to a significant decrease in elective endoscopic examinations in Germany. The main reasons for this were the hard lockdown and the lack of personal protective equipment (PPE) and testing procedures. Since then, international recommendations from professional societies on infection control in endoscopy have been published. The extent to which these have been implemented in Germany is unclear during the 2nd and 3rd waves in 2020/2021, most endoscopy units remained open and the level of adherence to international protection guidelines was high. A uniform "standard procedure" has not yet been published. The exact role and effectiveness of testing procedures to protect patients and staff during endoscopy was unknown, and reliable figures on staff and patient infections acquired/transmitted in endoscopy units in Germany were lacking. Thus, the most important finding of this work is the determined rate of coronavirus disease 2019 (COVID-19) in endoscopy facilities. The data show that the infection rate among staff in German clinics and practices in early 2021 averaged up to 5%; most of these were acquired in the private setting. Clinics with gastroenterological endoscopy units had significantly higher infection rates (10%) than, for example, dental and otolaryngology practices. This result indicates the need for continued PPE efforts. The most important factors for infection safety are fully vaccinated (or recovered) staff and patients, a decreasing prevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the use of PPE and-although controversial-the consistent use of screening tests.
