Data source

Disability Services National Minimum Data Set collection

Data pertaining to the National Disability Agreement (NDA) are collected through the Disability Services National Minimum Data Set (DS NMDS). This NMDS, managed by the AIHW, facilitates the annual collation of nationally comparable data about disability services. Services within the scope of the collection are those for which funding has been provided during the specified period by a government organisation operating under the NDA. An agency may receive funding from multiple sources. Where an agency is unable to differentiate service users according to funding source, they are asked to provide details of all service users for each service type. The transition of service users from the NDA to the National Disability Insurance Scheme (NDIS) reduced the collection of data under the National Disability Agreement. For this reason, comparisons between years should be approached with caution.

With the exceptions noted below, agencies are asked to provide information about:

  • each of the service types they provide (that is, service type outlets they operate)
  • all service users who received support over a specified reporting period
  • the Disability Services NMDS service type(s) the service users received.

However, certain service type outlets—such as those providing advocacy or information and referral services—are not requested to provide any service user details, and other service type outlets (such as recreation and holiday programs) are only asked to provide minimal service user details.

The collection includes those disability support service providers that provide services under the NDA—including some psychiatric-specific disability service providers and other disability service providers—that may be accessed by people with psychiatric disability. It should be noted that the NDA does not apply to the provision of services with a specialist clinical focus.

Data for the 2015–16 collection period were released in Disability support services: services provided under the National Disability Agreement 2015–16 (AIHW 2017). The scope of services varied in terms of programs provided across jurisdictions. For example, in Victoria and Queensland, specialist psychiatric disability services were provided under the NDA. However, in all other jurisdictions specific mental health services were funded and provided under the health, rather than the disability (or other), portfolio. In addition, Victoria has changed the way service users with a psychiatric disability were reported between Mental health services in Australia publications. Therefore, comparisons between publications should be approached with caution. See the Disability Services National Minimum Data Set 2015–16; Quality Statement and the DS NMDS collection guides.

Response rates

For the 2015–16 collection, there was an overall response rate of 96.4% for service outlets, although rates were variable across jurisdictions (DataSourceDIS.1). The response rates estimate the number of service outlets providing client data. Information on which service type outlets provided information for each collection period is not available as part of the Disability Services NMDS. Therefore, there is the possibility that, between collection periods, different outlets, with different proportions of psychiatric disability users, are providing service user information to the Disability Services NMDS. In addition, the number of non‑responses for the item 'Primary disability group' also varies considerably between jurisdictions. The service outlet response rates and the non-response rates for states and territories for 2005–06 to 2015–16 are shown in DataSourceDIS.1 below. The user response rate within these outlets cannot be estimated.

(a) Data from 2013–14 are affected by the roll-out of the NDIS.

(b) Some service type outlets in the Australian Capital Territory may have been less responsive because of the complexities associated with the changeover to the NDIS.

(c) The transition of clients into the NDIS in the Australian Capital Territory significantly reduced the ability of the territory's government to collect data under the NDA. For this reason, Australian Capital Territory data has not been included in the DS NMDS from 2015–16.

(d) Figures are the percentage of total responses for primary disability group.

Notes:

1. Service outlet response rates are based on figures provided by jurisdictions, and are the percentage of the total responses for each data item.

2. The total service outlet response rate is based on the number of outlets in the data set divided by the number of total outlets that would have been in the data set if all jurisdictions had a 100% response rate.

3. The methodology to obtain service user counts has varied over time, so comparisons between reporting years should be approached with caution.

4. The 'not stated' and 'not known' response table excludes some service types not required to collect service user data.

5. Some service types are only required to collect data relating to age and sex. These users are included in the 'not stated' and 'not known' table.

The statistical linkage key

Individuals may receive disability support services from more than one service provider, or from multiple jurisdictions. A statistical linkage key enables unique service user counts to be estimated from the data collected by service type outlets and agencies. To link records within the Disability Services NMDS, the statistical linkage key components of each record for a service received are compared electronically with the statistical linkage key components of all other records. Records that have matching statistical linkage keys are assumed to belong to the same individual service user and are linked. There is a small probability that some of the linked records do not actually belong to the same individual, and, conversely, that some records that did not link do belong to the same individual. More technical information on the use, calculation and validity of the statistical linkage key can be found in the supplementary tables to the publication, Disability support services: services provided under the National Disability Agreement 2015–16 (AIHW 2017), and in the associated Disability Services National Minimum Data Set 2014–15; Quality Statement.

Indigenous status

For 2015–16, the proportion of service users identifying as being Aboriginal and Torres Strait Islander people was higher than the proportion in the general population (5.4% versus 3.0%). See Disability support services: services provided under the National Disability Agreement 2015–16 ( AIHW 2017) for further information.
