Key terminology and glossary
Closed treatment episode
An episode of treatment for alcohol and other drugs is the period of contact, with defined dates of commencement and cessation, between a client and a treatment provider or team of providers in which there is no change in the main treatment type or the principal drug of concern, and there has not been a non-planned absence of contact for greater than 3 months.
A treatment episode is considered closed where any of the following occurs:
- treatment is completed or has ceased
- there has been no contact between the client and treatment provider for 3 months, or
- there is a change in the main treatment type, principal drug of concern or delivery setting.
Treatment episodes are excluded from the AODTS NMDS for a reporting year if they:
- are not closed in the relevant financial year
- are for clients who are receiving pharmacotherapy (through an opioid substitution therapy program) and not receiving any other form of treatment that falls within the scope of the collection
- include only activities relating to needle and syringe exchange, or
- are for a person aged under 10.
Drugs of concern
The principal drug of concern is the main substance that the client stated led them to seek treatment from the AOD treatment agency. In this report, only clients seeking treatment for their own substance use are included in analyses of principal drug of concern. It is assumed that only the person using the substance themselves can accurately report principal drug of concern; therefore, these data are not collected from those who seek treatment for someone else’s drug use.
Additional drugs of concern refers to any other drugs the client reports using in addition to the principal drug of concern. Clients can nominate up to 5 additional drugs of concern, but these drugs are not necessarily the subject of any treatment within the episode.
All drugs of concern refers to all drugs reported by clients, including the principal drug of concern and any additional drugs of concern.
Reasons for cessation
The reasons for a client ceasing to receive a treatment episode from an AOD treatment service include:
- expected/planned completion: episodes where the treatment was completed, or where the client ceased to participate at expiation or by mutual agreement
- ended due to unplanned completion: episodes where the client ceased to participate against advice, without notice or due to non-compliance
- referred to another service/change in treatment mode: episodes that ended due to a change in main treatment type, delivery setting or principal drug of concern, or where the client was transferred to another service provider.
- other: episodes that ended due to the client returning to court or jail due to non-compliance with a drug court program or sanctioned by court diversion service, imprisoned (other than drug court sanctioned), died, or reasons not elsewhere classified.
Treatment type refers to the type of activity used to treat the client’s alcohol or other drug problem. Rehabilitation, withdrawal management (detoxification) and pharmacotherapy are not available for clients seeking treatment for someone else’s drug use.
The main treatment type is the principal activity that is determined at assessment by the treatment provider to be necessary for the completion of the treatment plan for the client’s alcohol or other drug problem for their principal drug of concern. One main treatment type is reported for each treatment episode. ‘Assessment only’, 'support and case management' and 'information and education' can be reported only as main treatment types.
In 2019–20, changes were made to categories under Main Treatment; the word ‘only’ was removed from support and case management and information and education. The removal of the word ‘only’ from support and case management and information and education, changed reporting rules for agencies; allowing agencies to be able to report and more accurately capture these items as an additional treatment in conjunction with a main treatment type.
Other treatment types refer to other treatment types provided to the client, in addition to their main treatment type. Up to 4 additional treatment types can be reported.
Note that Victoria and Western Australia do not supply data on additional treatment types. In these jurisdictions, each type of treatment (main or additional) results in a separate episode.
additional drugs: Clients receiving treatment for their own drug use nominate a principal drug of concern that has led them to seek treatment and additional drugs of concern, of which up to 5 are recorded in the AODTS NMDS. Clients receiving treatment for someone else’s drug use do not nominate drugs of concern.
additional treatment type: Clients receive 1 main treatment type in each episode and additional treatment types as appropriate, of which up to 4 are recorded in the AODTS NMDS.

referral source: The source from which the client was transferred or referred to the alcohol and other drug treatment service.
standard drink: Contains 10 grams of alcohol (equivalent to 12.5 millilitres of alcohol). Also referred to as a full serve.
tobacco: A plant, Nicotiana tabacum, whose leaves are dried and used for smoking and chewing and in snuff. Its major pharmacologically active substance is the alkaloid nicotine (see nicotine).
treatment delivery setting: The main physical setting in which the type of treatment that is the principal focus of a client's alcohol and other drug treatment episode is actually delivered to a client (irrespective of whether or not this is the same as the usual location of the service provider).
treatment episode: The period of contact between a client and a treatment provider or a team of providers. Each treatment episode has 1 principal drug of concern and 1 main treatment type. If the principal drug or main treatment changes, then a new episode is recorded.
treatment type: The type of activity that is used to treat the client’s alcohol or other drug use, which includes:
- assessment only – where only assessment is provided to the client (service providers would normally include an assessment component in all treatment types)
- counselling – can include cognitive behaviour therapy, brief intervention, relapse intervention and motivational interviewing
- information and education – where information and education is provided to the client (service providers would normally include an information and education component in all treatment types)
- pharmacotherapy – where the client receives another type of treatment in the same treatment episode and includes drugs such as naltrexone, buprenorphine and methadone used as maintenance therapies or relapse prevention for people who experience dependence on certain types of opioids. Where a pharmacotherapy is used for withdrawal, it is included in the withdrawal category. Due to the complexity of the pharmacotherapy sector, this report provides only limited information on agencies whose sole function is to provide pharmacotherapy
- rehabilitation – focuses on supporting clients in stopping their drug use, and to prevent psychological, legal, financial, social and physical consequences of problematic drug use. Rehabilitation can be delivered in several ways, including residential treatment services, therapeutic communities and community-based rehabilitation services
- support and case management – support includes helping a client who occasionally calls an agency worker for emotional support, while case management is usually more structured than ‘support’. It can assume a more holistic approach, taking into account all client needs (including general welfare needs) and it includes assessment, planning, linking, monitoring and advocacy
- withdrawal management (detoxification) – includes medicated and non-medicated treatment to help manage, reduce or stop the use of a drug of concern.
