Data and data items

The CWDA is delivered via the National Health Data Hub (NHDH) and access to the CWDA is through AIHW-managed secure environments. The CWDA provides access to integrated data from child and young people-focused data collections outlined in Table 1.

 In addition, CWDA projects can request access to other data collections available through the NHDH. This will include access to the Pharmaceutical Benefits Scheme (PBS), the Medicare Benefits Schedule (MBS) and the National Community Mental Health Care Database. The NHDH web pages provide detailed information on all available data collections available through the NHDH.
