Registry of Hospitalized Patients in University Hospital Dubrava Respiratory Center

University Hospital Dubrava has been completely repurposed during the COVID-19 pandemic to become high volume COVID-19 tertiary institution. Establishment of hospital registry project is necessary to properly understand disease characteristic, related outcomes and real-life treatment patterns. Registry provides a fundamental framework for future upgrading with emerging or retrogradely obtained specific data that will substantially facilitate understanding of COVID-19 in the context of other specific diseases, therapies and procedures. Large comprehensive database will provide sufficient statistical power to allow for investigation of large number of subgroups and existence of interactions between different variables. Assessment of large number of clinically important outcomes (mortality, occurrence of venous and arterial thromboses, major bleeding, bacteriemia, incidence of mechanical ventilation and intensive care unit admission) is necessary to put any investigated parameter in the proper efficacy and safety context.
