ABSTRACT
INTRODUCTION: With more than 1400 COVID-19 inpatients, the university hospital of Essen is the main regional caregiver during COVID-19 pandemic. We present outcome data of our inpatients during the first 12 months of pandemic and our derived clinical care concepts. METHODS: Retrospective analysis of all 1396 COVID-19 inpatients presenting between March, 1st of 2020 and February, 28th of 2021 for comorbidities, survival and complications. Group comparison between patients receiving standard care and those requiring intermediate/ intensive care. RESULTS: Mortality rate of all inpatients was 19,8â% (277/ 1396), whereas 10.6â% (93/877) of the patients with standard care and 35.5â% (184/519) of those with intermediate/intensive care died during hospital stay. Age above 60 years, obesity, need for mechanical ventilation, nitric oxide therapy, ECMO and acute renal failure as well as stroke during the clinical course were independent predictors of mortality. CONCLUSIONS: The mortality of both patient groups ranges within the numbers published by other international groups. The vast impact of usual comorbidities could be observed as well as the high rate of complications in serious ill COVID-19 patients. The mean age of both patient groups was lower than expected (60 years standard care versus 63 years intermediate/ intensive care). A maximum of patient and staff protection measures, a fast and efficient testing strategy during primary triage, standardized concepts from emergency department to intensive care units and dynamic adjustment of resources to daily changing needs can ensure a high quality of care even during peak of pandemic.
