The term Drug Treatment Prevalence indicates all clients who are in drug treatment during the reporting year (1 January to 31 December) in a country

6. Case definition
A case is a client who is in treatment at a treatment centre during the calendar year:
- 1 January to 31 December for problems created by his/her drug use
- she/he can start a drug treatment episode or continue a treatment episode from previous year(s)
Exclusion criteria
Clients who ended the treatment by 31 December of the year before the reporting year are not included

7. Treatment status
For the purpose of collecting data, clients divided in 3 groups:
clients never previously treated starting drug treatment for the first time in their life
clients previously treated starting a new drug treatment episode during the year
clients in continuous treatment who have started a drug treatment episode in previous year(s) (before the reporting year) and continue during the current year
