About

This is a research group focused on the diagnosis, treatment and secondary prevention of Substance Use Disorder (SUD). The team is composed of clinicians of the Department of Internal Medicine at Germans Trias i Pujol University Hospital, a 600-bed teaching hospital in metropolitan Barcelona. They are involved in patient-centered clinical research on the most frequent complications of SUD and their main objective is to reduce the impact of SUD complications among those suffering the disease.

The research conducted by the group is supported by grants from Instituto de Salud Carlos III (ISCIII) through the collaborative platform Redes de Investigación Cooperativa Orientada a Resultados en Salud (RICORS) and from national agencies such as Plan Nacional Sobre Drogas (PNSD). The group is also recognised as Consolidated Research Group by the agency AGAUR, Catalan Government (2021 SGR 00945, 2017 SGR 316) and currently has eight active projects.

Keywords: Addiction medicine, substance use disorder, medical complications, alcohol use disorder.
