A XUEC (Xarxa d’Unitats d’Expertesa Clínica - Network of clinical expertise units) is a network of healthcare centres in Catalonia that work together to provide specialised care to patients with rare diseases of the same type or scope. Its goal is to ensure high-quality, coordinated care for all affected individuals across Catalonia.

A UEC (Unitat d’Expertesa Clínica - Clinical Expertise Unit) is a specific healthcare unit that belongs to the XUEC network and leads the care for a specific group of rare diseases.

At Hospital de Sant Pau, we are a Clinical Expertise Unit in 8 XUECs belonging to the Servei Català de Salut (Catalan Health Service), out of the 10 that operate in Catalonia.
