Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The Corona virus disease 2019 (COVID-19) pandemic is currently involving all parts of the world. Several risk factors for critical illness and death from the disease have been proposed. However, the observed associations between different comorbidities and chronic medications have not fully been related to the frequencies of the same comorbidities and chronic medications in age- and sex-matched controls from the general population. This is important since some of the proposed risk factors are very common in the aged who, by age alone, are more prone to a more severe course of the disease.

By combining several registries, we will compare, on several comorbidities such as hypertension and diabetes and several medications such as immunosuppressant drugs and Angiotensin Converting Enzyme (ACE)-inhibitors, the first 2000 cases of COVID-19 patients receiving critical care in Sweden to a set 8000 age- and sex-matched controls.

Data sources:

Registries of the Swedish board of Health and wellfare:

1. The patient registry containing information including diagnostic codes from all specialized Healthcare contacts in Sweden. Reporting i governed by law.
2. The Swedish Prescribed Drug Register to which all dispensations from pharmacies of prescribed drugs are reported.

Statistics Sweden is the agency responsible for the official population statistics of Sweden. They will draw our controls from the Registry of the total population.

The Swedish Intensive Care Registry (SIR) contains all intensive care episodes in Sweden. They have information on Intensive Care (ICU) admission, diagnoses, interventions and outcomes.

The study design is combined prospective ond retrospective. The data is prospectively collected to the registries but the study protocol is retrospectively designed.
