Brief Summary
The German Asthma Net e.V. focusses on science and research in patients with severe asthma. This includes, in particular, the optimization of medical care and treatment for patients with severe asthma as well as the elucidation and information. An unavoidable basis for a better understanding of severe asthma is the registration and comprehensive characterization of a large patient population. To date, there are only few reliable data on incidence, prevalence, phenotypes and treatment of patients with severe asthma. For this reason, the German Asthma Net e.V. was established in December 2011 as a clinical registry for patients with severe asthma, initially set up on a national basis.
