Long Term Outcome in ICU Treated COVID-19: New Chronic Diseases

Additional chronic diseases one year after intensive care unit (ICU) admission with Coronavirus disease 2019 (COVID-19) will be assessed in comparison to two control cohorts. The ICU population comprises all Swedish ICU patients with COVID-19 with at least one year of follow up. The hospital admitted cohort comprises four hospital admitted patients with COVID-19 per ICU patient, matched on age, legal gender and region. The general population controls are matched to the ICU patients in a one to four fashion on age, legal gender and region. ICU patients are identified in the Swedish intensive care registry. The hospital admitted patients are identified in the national patient registry and the population controls are identified in the population registry. Data on comorbidity, medications and death are provided from the National board of health and welfare.
