NT Health Data Ownership

The Northern Territory of Australia (Territory) is the legal owner of all data collected by, within and for NT Health.  The Chief Executive of the Department has primary responsibility (on behalf of the Territory) for the security, management, use and disclosure of the data. NT Health delegates ownership of the various categories of data (i.e. financial, workforce, activity and patient/client level information) across the agency and therefore it is necessary to gain approval from the relevant data owner(s) prior to the use/release of data.

NT Health further separates the responsibility of data ownership based on the guiding principles of primary and secondary use of data.  Primary use data such as quality assurance or quality improvement activities, clinical audits, management of health services and teaching activities is governed by system or collection owners within NT Health.  Secondary use of data is governed by the NT Health data release guidelines.
