 What we do

IDAS provides inpatient withdrawal management (detoxification) and Involuntary Drug and Alcohol Treatment (IDAT).

IDAS is an 11 bed, 7 day / 24 hour, inpatient unit at Royal North Shore Hospital. The unit provides medically supervised withdrawal management from alcohol and drugs along with an educational/therapeutic program which includes groups and case management. Provision of comprehensive medical and psychiatric assessment as well as aftercare planning is also a core component of the program.

The IDAT Program provides short term care, with an involuntary supervised withdrawal component, to protect the health and safety of people with severe substance dependence who have experienced, or are at risk of, serious harm and whose decision making capacity is considered to be compromised due to their substance use.

The Drug and Alcohol Treatment Act 2007 (the Act) provides the legislative basis for the Program. The Act provides for the health and safety of persons with severe substance dependence through involuntary detention, care, treatment and stabilisation.

To be considered for treatment under the Act a person must meet all of the following criteria:

  1. The person has a severe substance dependence, and
  2. Care, treatment or control of the person is necessary to protect the person from serious harm, and 
  3. The person is likely to benefit from treatment for his or her substance dependence but has refused treatment, and
  4. No other appropriate and less restrictive means for dealing with the person are reasonably available.

The IDAT Program has a state-wide intake, but is delivered out of Royal North Shore Hospital in St Leonards, where there are 4 designated IDAT beds, and Bloomfield Hospital in Orange, where there are 8 designated IDAT beds. The Program provides up to 28 days inpatient involuntary treatment under a dependency certificate issued by a medical practitioner who has been accredited by NSW Health to issue such certificates.

The dependency certificate is then reviewed by a magistrate as soon as practicable, but ideally no more than 7 days after it was issued. The magistrate affirms that, on the balance of probability, the person under the dependency certificate meets the criteria for detention under the Act. The accredited medical practitioner may apply to the magistrate for an extension of the dependency certificate for a maximum period of 56 days. In order to grant such as extension, the magistrate must be satisfied that the person is suffering from a drug or alcohol related brain injury and that additional time is needed to carry out treatment and to plan the person's discharge.
