4.3 Myocardial perfusion scans, 18 years and over

The Third Australian Atlas of Healthcare Variation investigates healthcare use in four clinical areas. Myocardial perfusion scans are included in Chapter 4, Cardiac tests.

Why is this important?

Cardiac stress tests and imaging are used in people with symptoms suggestive of coronary heart disease for accurate diagnosis, risk assessment and treatment planning (for example, treatment with revascularisation by stenting or bypass surgery). Equitable access to cardiac imaging is important for improving cardiac care and outcomes in people at high risk of coronary artery disease in Australia.

Appropriate use of these tests is also important for the sustainability of the health system, as they account for a substantial portion of the health budget. Use of cardiac imaging has grown at about twice the rate of treatment with revascularisation – suggesting that some testing is unnecessary and that healthcare resources could be better used.

Rates of use of stress echocardiography have risen rapidly in recent years, with variation in use across Australia. There are concerns about both overservicing in some areas and underservicing in others.

About the data

About the data - Myocardial perfusion scans, 18 years and over

Data are sourced from the MBS dataset. This dataset includes information on MBS claims processed by the Australian Government Department of Human Services. It covers a wide range of services (attendances, procedures, tests) provided across primary care and hospital settings.

The dataset does not include:

  • for publicly funded patients in hospitals
  • for patients in hospital outpatient clinics where claims are not made to the MBS
  • covered under Department of Veterans’ Affairs arrangements.

Rates are based on the number of MBS-subsidised services for MPS per 100,000 people aged 18 years and over in 2016–17.

Because an MBS claim is included for each service rather than for each patient, patients who receive any of the services listed in this data item more than once in the financial year will have more than one MBS claim counted.

The analysis and maps are based on the residential address of the patient recorded in the MBS claim and not the location of the service.

Rates are age and sex standardised to allow comparisons between populations with different age and sex structures.

This analysis was not undertaken by Aboriginal and Torres Strait Islander status because this information was not available for the MBS data at the time of publication.

Data suppression

For all items in the Atlas, some data have been suppressed to manage the low number of events and/or very small populations in some areas, to protect the identity of patients and providers.

This process takes into account the Australian Government Department of Health’s requirements for reporting MBS data (see Technical Supplement). The process has resulted in particularly marked data suppression for MPS MBS items. This is indicated on the maps in grey. Most local areas (Statistical Area Level 3 – SA3) were suppressed to prevent identification of the provider (practitioner or business entity). The effect of data suppression was greatest in inner and outer regional and remote areas:

  • Overall, 62 SA3s were suppressed, which represents 18% of all SA3s and 8% of all services
  • 37 SA3s were suppressed to prevent identification of the provider
  • The proportion of SA3s suppressed in each remoteness category was 3% in major cities, 26% in inner regional areas, 43% in outer regional areas and 74% in remote areas
