Alcohol and Other Drug Treatment Services National Minimum Data Set (AODTS NMDS)

Data sources

The Alcohol and Other Drug Treatment Services National Minimum Data Set (AODTS NMDS) is the primary source used in this analysis. It provides information on the treatment provided by publicly-funded alcohol and other drug treatment agencies in Australia. These services are available to people seeking treatment for their own drug use and people seeking treatment for someone else's drug use. Data are available from 2003–04 onwards.

In the AODTS NMDS, the main counting unit is a closed treatment episode, which is defined as a period of contact between a client and a treatment provider (or team of providers) that is closed when treatment is completed or has ceased, or there has been no further contact between the client and the treatment provider for 3 months. Since 2012–13, a statistical linkage key (SLK) has been collected which means the number of clients receiving treatment can now be estimated .

Other data sources

A number of other data sources include information not available in the AODTS NMDS. Using these additional data sets supports more comprehensive reporting of alcohol and other drug treatment in Australia. These include the National Opioid Pharmacotherapy Statistics Annual Data Collection (NOPSAD), the National Hospital Morbidity Database, Aboriginal and Torres Strait Islander health organisations: Online Services Report Database, the Specialist Homelessness Services (SHS) Collection and the National Prisoner Health Data Collection (NPHDC).

In 2014–15:

  • of the 1% of hospital separations with a drug-related principal diagnosis, alcohol accounted for 53% of separations;
  • for the 25,200 clients receiving Aboriginal and Torres Strait Islander primary health-care services, alcohol and cannabis were among the top 5 most common substance-use issues;
  • 11% of Specialist Homelessness Services (SHS) clients aged 10 years or over had a current alcohol and other drug issue.

In 2015, of the 1,011 prison entrants in the National Prisoner Health Collection (NPHDC), two-thirds (67%) reported using illicit drugs in the previous 12 months—1 in 2 (50%) reported using methamphetamines, and 2 in 5 (41%) cannabis.
