European Reference Networks (ERN)

The European Reference Networks (ERNs) are cross-border networks that bring together leading hospitals across Europe to cooperate on rare, low prevalence and complex diseases requiring highly specialised healthcare. These networks enable European specialists share knowledge and expertise, discuss challenging cases, and provide guidance on the most appropriate diagnosis and the best treatment available.

As of 2025, there are 24 ERNs created under Directive 2011/24/EU on patients’ rights in cross-border healthcare. Launched in March 2017, the networks now include 1619 specialized centers across 382 hospitals in 27 EU Member States and Norway.

Aarhus University Hospital serves as both the local hospital of Aarhus and a university hospital which brings with it a unique responsibility in the field of rare and complex diseases. There are patient groups with rare conditions who require ongoing efforts to improve treatment options. As a university hospital, AUH is required to take the lead in advancing expertise and ensuring the highest standards of care.

Aarhus University Hospital (AUH) is a member of 19 European Reference Networks, working collaboratively within these cross-border networks to enhance treatment options for patients with rare and complex diseases across Europe. Through its involvement, AUH not only enhances quality of care for its own patients but also contributes to bettering treatment for patients across Europe, ensuring access to the latest expertise and most effective treatments available.
