Heart, stroke and vascular disease: Australian facts

In 2011–13, the Australian Heath Survey incorporated the first Australian Bureau of Statistics (ABS) biomedical collection – the National Health Measures Survey. It involved the collection of a range of blood and urine tests from over 11,000 participants across Australia, which were then tested for various chronic disease and nutrient biomarkers.

Urine samples were collected from respondents aged 5 and over, and blood samples from respondents aged 12 and over. 36% of the survey participants volunteered to get the biomedical tests, covering 85% of the sampled households.

In 2012–13, the Australian Aboriginal and Torres Strait Islander Health Survey incorporated the first biomedical collection to be undertaken for the First Nations population in an ABS survey – the National Aboriginal and Torres Strait Islander Health Measures Survey (NATSIHMS). It involved the collection of a range of blood and urine tests from approximately 3,300 participants aged 18 years and over across Australia.

The NATSIHMS measured specific biomarkers for chronic disease and nutrition status, derived from tests on blood and urine samples from volunteering participants selected in the Australian Aboriginal and Torres Strait Islander Health Survey.

The National Health Survey (NHS) is conducted by the Australian Bureau of Statistics to obtain national information on the health status of Australians, their use of health services and facilities, and health-related aspects of their lifestyle.

The NHS collects self-reported data on whether a respondent had 1 or more long-term health conditions; that is, conditions that lasted, or were expected to last, 6 months or more.

The NHS refers to ‘heart, stroke and vascular disease’, which comprises people who reported having been told by a doctor or a nurse that they had any of a range of circulatory conditions comprising:

• ischaemic heart diseases (angina, heart attack and other ischaemic heart diseases)
• cerebrovascular diseases (stroke and other cerebrovascular diseases)
• oedema
• heart failure
• diseases of the arteries, arterioles and capillaries,

and that their condition was current and long-term; that is, their condition was current at the time of interview and had lasted, or was expected to last, 6 months or more.

Persons who reported having ischaemic heart diseases, cerebrovascular diseases and heart failure that were not current and long term at the time of interview are also included.

When interpreting data from the 2017–18 NHS, some limitations need to be considered:

• data that are self-reported rely on respondents knowing and providing accurate information
• the survey does not include information from people living in nursing homes or otherwise institutionalised
• residents of Very remote areas and discrete First Nations communities were excluded from the survey. This is unlikely to affect national estimates, but will impact prevalence estimates by remoteness.

Further information can be found in National Health Survey: First results, 2017–18.

The National Aboriginal and Torres Strait Islander Health Survey (NATSIHS) is conducted by the Australian Bureau of Statistics to obtain national information on the health of First Nations people, their use of health services and health-related aspects of their lifestyle. The most recent NATSIHS was conducted in 2018–19.

The NATSIHS collects information from First Nations people of all ages in non-remote and remote areas of Australia, including discrete First Nations communities.

Further information can be found in ABS National Aboriginal and Torres Strait Islander Health Survey, 2018–19.

The Survey of Disability, Ageing and Carers (SDAC) is conducted by the Australian Bureau of Statistics to collect information about people of all ages with a disability, older people aged 65 and over, and carers of people with disability or a long-term health condition or older people. The surveys included people in both private and non-private dwellings (including people in establishments where care is provided) but excluded those in correctional institutions.

ABS SDAC 2018 has been used in this report to provide estimates on the prevalence of stroke. SDAC includes comprehensive questions on long-term conditions and associated activity limitations, and includes non-private dwellings, such as residential aged care facilities. This is particularly important when reporting on stroke because stroke is associated with increasing age, and many survivors of stroke require the special care that these facilities provide.

Further information can be found in ABS Disability, Ageing and Carers, Australia: Summary of Findings, 2018.

The AIHW National Hospital Morbidity Database (NHMD) is a compilation of episode-level records from admitted patient morbidity data collection systems in Australian hospitals.

Reporting to the NHMD occurs at the end of a person’s admitted episode of care (separation or hospitalisation) and is based on the clinical documentation for that hospitalisation.

The NHMD is based on the Admitted Patient Care National Minimum Data Set (APC NMDS). It records information on admitted patient care (hospitalisations) in essentially all hospitals in Australia, and includes demographic, administrative and length-of-stay data, as well as data on the diagnoses of the patients, the procedures they underwent in hospital and external causes of injury and poisoning.

The hospital separations data do not include episodes of non-admitted patient care given in outpatient clinics or emergency departments. Patients in these settings may be admitted subsequently, with the care provided to them as admitted patients being included in the NHMD.

The following care types were excluded when undertaking the analysis: 7.3 (newborn – unqualified days only), 9 (organ procurement – posthumous) and 10 (hospital boarder).

The National Hospital Morbidity Database include information on people’s area of usual residence at the time of hospitalisation. 

For 2021–22, this was their SA2 based on the 2016 ASGS. In this report, 2016 SA2 values have been concorded to SA2 values based on the 2021 census prior to calculating rates

Further information about the NHMD can be found in Admitted patient care NMDS 2021–22- external site opens in new window.

The AIHW National Mortality Database (NMD) comprises information about causes of death and other characteristics of the person, such as sex, age at death, area of usual residence and First Nations status. The cause of death data are provided to the AIHW by the Registries of Births, Deaths and Marriages and the National Coronial Information System (managed by the Victorian Department of Justice) and include cause of death coded by the ABS. The data are maintained by the AIHW in the NMD.

In this report, deaths registered in 2019 and earlier are based on the final version of cause of death data; deaths registered in 2020 are based on the revised version; and deaths registered in 2021 and 2022 are based on the preliminary version. Revised and preliminary versions are subject to further revision by the ABS.

For data by Indigenous status, counts of death are reported for 8 jurisdictions combined – New South Wales, Australian Capital Territory, Victoria, Queensland, Western Australia, South Australia, Tasmania and the Northern Territory. Death rates are reported for 5 jurisdictions combined – New South Wales, Queensland, Western Australia, South Australia and the Northern Territory. These jurisdictions are considered to have adequate levels of First Nations identification in mortality data.

This report adjusts for Victorian additional death registrations of deaths that were registered in Victoria in 2017 and 2018 but were not provided to the ABS for compilation until 2019. As a result, the number of diabetes deaths reported for 2017 to 2019 may differ from previously reported numbers. For more detail, see the Technical note: Victorian additional registrations and time series adjustments in Causes of death, Australian methodology- external site opens in new window.

The NMD includes information on people’s area of usual residence prior to death. For 2022, this was their SA2 based on the 2021 ASGS. This location information from the National Mortality Database, along with IRSD values based on the ABS 2021 Census of Population and Housing, and estimated resident populations for 2022, have been used to approximate statistics for 2022 ASGS Remoteness Areas and 2022 IRSD SEIFA quintiles.

The AIHW Disease Expenditure Database provides a broad picture of the use of health system resources classified by disease groups and conditions. 

It contains estimates of expenditure by Australian Burden of Disease Study condition, age group, and sex for admitted patient, emergency department, and outpatient hospital services, out-of-hospital medical services, and prescription pharmaceuticals. 

It does not allocate all expenditure on health goods and services by disease – for example, neither administration expenditure nor capital expenditure can be meaningfully attributed to any particular condition due to their nature.

For more information, see Health system spending on disease and injury in Australia, 2020-21.

In the 2020–21 study compared to previous disease expenditure studies, there were changes to the methods used for MBS mapping, Emergency Department (ED) analysis, Non-admitted patient analysis (NAP) and the identification of COVID-19 cases. 

For further details on the methods used, refer to Health system spending of disease and injury in Australia: Overview of analysis and methodology 2020–21.

The Australian Burden of Disease Study undertaken by the AIHW provides information on the burden of disease for the Australian population. Burden of disease analysis measures the impact of fatal (or years of life lost, YLL) and non-fatal burden (years lived with disability, YLD), with the sum of non-fatal and fatal burden equating the total burden (disability-adjusted life year, DALY).

The Australian Burden of Disease Study 2023 includes national estimates for 220 diseases and injuries including estimates of burden for COVID‑19 in 2023 based on projections using historical trends in data. The ABDS 2023 is different to the 2003, 2011, 2015 and 2018 studies in that estimates have been produced for the current year (2023). It builds on work from the ABDS 2022, which was the first study where burden was estimated for the year of release (2022). This Study provides burden of disease estimates best matched to the public health context for the Australian population for 2023. 

The 2018 study also provides estimates of how much of the burden can be attributed to 20 different risk factors. It also includes a component on the impact and causes of illness and death in First Nations people, which includes estimates of the gap in disease burden between First Nations people and non-Indigenous Australians. Estimates of the burden of disease for First Nations people are available for 2003, 2011 and 2018.

For more information, see the Burden of disease.

The AIHW National Non-admitted Patient Emergency Department Care Database (NNAPEDCD) is a compilation of episode-level records (including waiting times for care) for non-admitted patients who are registered for care in emergency departments in selected public hospitals. The database captures information only for physical presentations to emergency departments and does not include advice provided via telehealth or videoconferencing.

Patients being treated in emergency departments may be later admitted, including admission in the emergency department, another hospital ward or to hospital‑in-the-home. For this reason, there is an overlap in the scope of the NNAPEDCD, the NMDS and the APC NMDS.

For 2022–23, this was their SA2 based on the 2016 ASGS. In this report, 2016 SA2 values have been concorded to SA2 values based on the 2021 census prior to calculating rates.

Principal diagnoses for episodes of care in the NNAPEDCD 2022–23 are coded according to the Emergency Department ICD-10-AM Principal Diagnosis Shortlist. - external site opens in new window

MedicineInsight is a database containing de-identified electronic health records (EHRs) from over 700 Australian general practices.

MedicineInsight data include information on people living with diabetes and their interaction with the primary health care system through general practice.

Patient population percentages have been weighted to adjust for an over-representation of registered GP sites in Tasmania.
