Suppression and Restricted Data

In order to protect the anonymity of treatment service users, figures in the public areas of this site have been suppressed if they have a cell value of less than five (5). Such occurrences are indicated by a field containing "*" rather than a numeric value. This is because of the issue of “deductive disclosure”; the possibility (however remote) that information could be combined from several sources to identity individuals in contact with drug treatment services.

Access to unsuppressed statistics is restricted, and is provided solely for management, quality assurance, and briefing purposes. It is currently the policy of the NTA that service provider staff will not be given access to the restricted area of NDTMS. Service providers can access service specific data via their existing access to the DAMS system.

To request access to NDTMS.net, please follow the instructions on the registration page.
