We will characterize the most severe COVID-19 disease trajectories, i.e we will describe clinical phenomina, disease severity and cause of mortality of all Norwegian COVID-19 patients that reached intensive care units (ICUs) and thus is included in the Norwegian Intensive Care Registry (NIR). This will provide valuable knowledge about different patient trajectories and outcome of ICU stay related to COVID-19 in a Norwegian setting.
• For those patients with COVID-19 that survive ICU, we will do follow-up analysis regarding long-term functional outcomes and late cause of mortality (after discharge from ICU). We will give knowledge about the needs of receipt of medical benefits (measured by granted sickness benefits and disability pension) and decreased work ability after discharge from hospital. This will give valuable knowledge about severe COVID-19 and inform policy makers.
• Other important long-term functional outcomes is the use of general practitioner, readmission rates to hospital and needs of assistance in municipal health and care services, including domiciliary care for ICU patients with COVID-19 that survives hospital discharge. For primary care services and policy makers, this is of paramount importance to improve postacute care following severe COVID-19.
• For all above points we have the possibility to compare and contrast against sepsis of other causative agents like the common bacteria S.Pneumonia, E. Coli and S.Aureus (Regional Ethical Approval 42722), which is especially important as many have suggested that COVID-19 patients often die from secondary bacterial infections.
