Impact of the COVID-pandemic on the incidence of tonsil surgery and sore throat in Germany.

PURPOSE: To longitudinally evaluate the impact of the COVID-19-pandemic on the incidence of inpatient tonsil surgery and outpatient primary care of sore throat in Germany. METHODS: A retrospective interrupted time-series analysis was conducted. The national database of the Hospital Remuneration System was used to retrieve the number of operations performed between January 2019 and September 2021 including elective and non-elective cases with the exception of malign diseases. Three episodes were compared on a weekly basis: before, during, and after the first national lockdown (March 16-May 3, 2020). We also analysed the number of outpatient doctor contacts of sore throat patients in 2019 and 2020. RESULTS: Overall, 144,069 surgical cases were included in the analysis. The first lockdown resulted in an abrupt and significant decrease of all types of tonsil surgery (p < 0.01). The incidence of tonsillectomy decreased from 556 (before) to 111 (during) and 326 (after) cases per week (relative risk 0.24; 95% CI 0.19-0.30, and 0.82; 95% CI 0.73-0.92). After the lockdown, the incidence persisted on a lower level compared to 2019. The number of doctor contacts decreased from 2,967,322 in 2019 to 1,976,617 in 2020 (- 33.4%). CONCLUSIONS: The first lockdown was associated with a significant decrease of all types of tonsil surgery. A return to pre-pandemic surgical activity was not identified. The findings were accompanied by a significant decrease of outpatient doctor contacts of sore throat patients in primary care, particularly in the subgroup of children and adolescents. The impact of the second lockdown, starting in December 2020, was by far not comparable.

Characteristics and Unexpected COVID-19 Diagnoses in Resuscitation Room Patients during the COVID-19 Outbreak-A Retrospective Case Series.

INTRODUCTION: Emergency department (ED) triage regarding infection with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is challenging. During the coronavirus disease 2019 (COVID-19) outbreak in Germany, the diagnostic outcomes of critically ill patients admitted to the resuscitation room in the ED of our academic 754-bed hospital should be analyzed. METHODS: All resuscitation room patients between March 1st and April 15th 2020 were included in this retrospective study. Every patient with suspicion of SARS-CoV-2 infection received a pharyngeal swab for real-time polymerase chain reaction (rt-PCR), divided in the clinical subgroups of "highly suspicious for COVID-19" and "COVID-19 as differential diagnosis." All respiratory and infectious symptoms were included as at least "differential diagnosis" as an expanded suspicion strategy. RESULTS: Ninety-five patients were included (trauma n = 14, critically ill n = 81). Of 3 highly suspicious patients, 2 had rt-PCR positive pharyngeal swabs. In 39 patients, COVID-19 was defined as differential diagnosis, and 3 were positive for SARS-CoV-2. Of them, pharyngeal swabs were positive in 1 case, while in 2 cases, only tracheal fluid was rt-PCR positive while the pharyngeal swabs were negative. In one of these 2 cases, chest computed tomography (CT) was also negative for ground-glass opacities but showed a pulmonary abscess and pulmonary embolism. CONCLUSION: We recommend an expanded suspicion strategy for COVID-19 due to unexpected diagnostic outcomes. Personal protective equipment should be used in every resuscitation room operation due to unexpected cases and initial knowledge gaps. Furthermore, tracheal fluid should be tested for SARS-CoV-2 in every intubated patient due to cases with negative pharyngeal swabs and negative chest CT.
