2017-18 National Health Survey
The 2017-18 National Health Survey (NHS) is an Australia-wide health survey conducted by the Australian Bureau of Statistics (ABS). The 2017-18 NHS collected information about the health of Australians, including:
- prevalence of long-term health conditions;
- health risk factors such as smoking, overweight and obesity, alcohol consumption and physical activity;
- demographic and socioeconomic characteristics;
- geospatial data; and
- information on the health literacy of respondents.
The survey was conducted from July 2017 to June 2018, and included around 21,000 people in more than 16,000 private dwellings. More information is available in the publication National Health Survey: First Results, 2017-18.
Multi-Agency Data Integration Project
The Multi-Agency Data Integration Project (MADIP) is a partnership among Australian Government agencies to develop a secure and enduring approach for combining information on healthcare, education, government payments, personal income tax, and population demographics (including the Census) to create a comprehensive picture of Australia over time.
Information is combined via linking person-level datasets to the Person Linkage Spine (the ‘spine’), a key piece of linking infrastructure that serves as a base dataset representing the ‘ever-resident’ population of Australia. For more information on the Person Linkage Spine, how it was built and an assessment of its quality, see the paper Person Linkage Spine Methodology and Quality Assessment (available on request from Data.Services).
Why integrate the NHS with MADIP?
Integration of the 2017-18 NHS dataset with the Spine and MADIP analytical data has a strong public benefit as it enables rich insights to help provide better health care. The high level policy issues that can be informed by this data source include:
- the connection between people’s lifestyles, risk factors and health conditions and their service use and benefits paid;
- the impact of health status and health conditions on social and economic participation;
- the extent to which use of pharmaceuticals and medical services are consistent with appropriate pathways of care and meet clinical needs;
- patterns of use of healthcare services for different patient cohorts;
- quality and safety of services provided; and
- validation of models for provision of care.
The ABS actively considers and manages the privacy impacts of this linkage. Two relevant Privacy Impact Assessments have been undertaken - Linkage of the National Health Survey with MADIP and the 2019 MADIP PIA Update. Both can be found here.
