Collection and usage attributes
|Population group age from:|
Rates are directly age-standardised to the 2001 Australian population.
Count (a) number of deaths where ‘acute coronary heart disease’ (International Classification of Diseases 10th Revision (ICD-10) codes I20–I24) is the underlying cause of death in each calendar year (based on year of registration of death).
Count (b) number of non-fatal hospital separations where ‘acute myocardial infarction’ (ICD-10-AM I21) or ‘unstable angina’ (ICD-10-AM I20.0) is the principal diagnosis, and separation mode is not equal to ‘died’ or ‘transferred to another acute hospital’, and care type is equal to acute care in each calendar year (based on discharge date from hospital).
The number of acute coronary events is estimated by (a) + (b).
100,000 x (Numerator ÷ Denominator)
Number of deaths recorded with an underlying cause of acute coronary heart disease (a) plus the number of non-fatal hospitalisations with a principal diagnosis of acute myocardial infarction or unstable angina that do not end in death or a transfer to another acute hospital (b). For ages 25 and over.
|Numerator data elements:|
Total population aged 25 and over for calendar year in question.
|Denominator data elements:|
2016, 2017 (resupplied for revisions to the National Mortality Database), and 2018—Nationally, by:
2016, 2017 (resupplied for revisions to the National Mortality Database), and 2018—State/territory of usual residence.
2016, 2017 (resupplied for revisions to the National Mortality Database), and 2018—Nationally (for states and territories with adequate identification in both hospital and deaths data), by:
|Disaggregation data elements:|
Most recent data available for 2021 National Healthcare Agreement performance reporting: 2018.
This is a measure of the number of acute coronary events in a calendar year. An individual may have more than one event during a year.
This indicator has previously been published at the national level by age and sex.
The data for state/territory (of usual residence) has previously been published. Comparison of acute coronary event rates between jurisdictions should not be made as an AIHW assessment of validity study (based on New South Wales and Western Australia data) has shown that there are variations in the ascertainment of acute coronary events between jurisdictions. This is likely due to differing treatment and referral patterns and data recording practices across states/territories, which are likely to have an impact on administrative records and affect jurisdictional comparability.

|Further data development / collection required:|
Specification: Any further improvements in diagnostic sensitivity and treatment patterns for acute coronary events will need to be taken into account in trend analysis.
