[Experiences from the German COVID-19 register]

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections represent a particular risk for several groups of patients with nephrological diseases. Patients on dialysis represent a particularly vulnerable group during the SARS-CoV‑2 pandemic. Initial data from international registries show a much higher mortality of dialysis patients with SARS-CoV‑2 infections. Because of the substantial differences between the healthcare systems, (state) preventive measures and treatment possibilities etc., in the different countries worldwide, local and national registry data cannot be easily transferred. In order to gain a reliable overview of the prevalence and mortality of dialysis patients with SARS-CoV‑2 infection in Germany, the German Society of Nephrology implemented a national registry for dialysis patients with a SARS-CoV‑2 infection. Within this framework a standardized collection of these data is carried out on a weekly basis, which should enable a real-time overview of the case numbers and perhaps the acquisition of new scientific knowledge. Particularly in the current phase of the pandemic (autumn 2020), which is accompanied by a multiplication of the numbers of daily new-onset cases within only a few weeks, such data are highly relevant for the estimation and adjustment of the personnel, structural and organizational needs as well as the capacities for the treatment of patients.
