We initiated the Lean European Open Survey on SARS-CoV‑2 (LEOSS) project, a prospective European multi-center cohort study, to get more in-depth knowledge about the epidemiology and clinical course of patients infected with SARS-CoV‑2. Our goal is to establish a quick and simple register that allows anonymous documentation of patients. The study will allow retrospective inclusion of patients treated before the initiation of the study.
The obtained data can be used to identify independent predictors of outcome in patients with diagnosed infection by SARS-CoV‑2. The Data Use and Access Policy developed within the LEOSS community allows a dynamic and fast scientific use of the data while maintaining high scientific quality as well as responsible public communication.
