Danish Depression Database (DDD)
The DDD monitors the quality of treatment of depression in Denmark and was also designed to facilitate research. The database was launched in 2011 and includes individuals who have either been admitted to one of the nearly 60 psychiatric hospital wards (inpatients) or treated at one of the 190 hospital outpatient clinics in Denmark. Only individuals aged above 18 years with permanent residence in Denmark are registered in the database. Every year since its launch, approximately 5,500 inpatients and 7,500 outpatients have been registered annually in the database. A total of 24,083 inpatients and 29,918 outpatients have been registered.
