CORONA Germany is a multicenter, observational, prospective, epidemiological cohort study at 45 hospitals in Germany, all part of a German hospital network. From January 1st till November 17th, 2020, all hospitalized patients tested positive for SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) will be included. Demographical data and outcomes will be assessed in the entire study cohort. In a subgroup, consisting of 7 hospitals, further detailed data (e.g. baseline characteristics, laboratory values, medication, clinical events) will be assessed. Additionally, there will be subgroups of patients with cardiovascular events and prior or preexisting oncological diseases. There are two primary endpoints: 1. Combination of all-cause death and/or need for mechanical ventilation and/or allocation to intensive care unit (ICU). 2. Occurrence of a clinical manifest cardiovascular events. The aim of the study is the development of a prediction model for the primary endpoints, whereas the secondary endpoint is a comparison of mortality rates between the 1st (01/01/20-09/15/20) and 2nd (15/09/20) infection wave. All endpoints will be verified by an Endpoint Review Committee. A Steering Committee, consisting of representatives of the 45 hospitals, the trial statistician and members of the scientific department, takes responsibility of the study design and results.
