National Drug Treatment Reporting System

The National Drug Treatment Reporting System (NDTRS) is an epidemiological database on treated drug and alcohol misuse in Ireland. It was established in 1990 in the Greater Dublin Area and was extended in 1995 to cover all areas of the country.

Data collection for the NDTRS is carried out via an online web-based system. For detailed information about this, and/or how to contribute / participate, please contact the team at ndtrs(at)

The NDTRS was originally developed in line with the Pompidou Group Definitive Protocol and subsequently refined in accordance with the European Monitoring Centre for Drugs and Drug Addiction Treatment Demand Indicator Protocol. Since 2004, clients reporting alcohol as their main problem drug have been recorded by the system. 

  • Treatment is broadly defined as any activity which aims to ameliorate the psychological, medical or social state of individuals who seek help for their substance misuse problems. Clients who attend needle-exchange services are not included in this reporting system.
  • Treatment options include one or more of the following: medication (detoxification, methadone reduction, substitution programmes and psychiatric treatment), brief intervention, counselling, group therapy, family therapy, psychotherapy, complementary therapy and life-skills training.
  • Treatment is provided in both residential and non-residential settings.
