In-hospital outcomes of healthcare-associated COVID-19 (Omicron) versus healthcare-associated influenza: a retrospective, nationwide cohort study in Switzerland.

Background: As COVID-19 is integrated into existing infectious disease control programs, it is important to understand the comparative clinical impact of COVID-19 and other respiratory diseases.

Methods: We conducted a retrospective cohort study of patients with symptomatic healthcare-associated COVID-19 or influenza reported to the nationwide, hospital-based surveillance system in Switzerland. Included patients were adults (≥18 years) hospitalized for ≥3 days in tertiary care and large regional hospitals.

Swiss COVID-19 hospital surveillance: an in-depth analysis of the factors associated with hospital readmission dynamics in community-acquired COVID-19 cases.

Background: The COVID-19 pandemic has placed unprecedented pressure on hospitals worldwide. In such a context of tension in healthcare systems, efficiently allocating hospital resources is a crucial aspect of crisis management. The aim of this study was to describe the clinical characteristics of readmitted patients and to determine risk factors for hospital readmission using data from the Swiss COVID-19 Hospital-Based Surveillance system (CH-SUR).

Hospital-acquired respiratory viral infections while applying droplet precautions on-site (DroPS) - prospective observation during the 2019/20 influenza season, Bern, Switzerland.

Single room isolation for respiratory viral infections (RVI), like influenza, puts hospitals under pressure. During the influenza season 2019/20, we implemented (DroPS) for RVI in two acute care hospitals and prospectively assessed the rate of hospital-acquired RVI (HARVI). 318 patients were admitted with RVI, 85 had Influenza or RSV, 75 stayed in multi-bed rooms with DroPS.
