National Healthcare Agreement: PI 09–Incidence of heart attacks (acute coronary events), 2016

Collection and usage attributes

Rates directly age-standardised to the 2001 Australian population.

Count (a) number of deaths where ‘acute coronary heart disease’ (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) are the principal diagnosis, and separation mode is not equal to ‘died’ or ‘transferred to another acute hospital’, and care type is not equal to Newborns without qualified days or posthumous organ procurement or hospital boarder 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 a transfer to another acute hospital (b). For ages 25 years and over.

Total population aged 25 years and over for calendar year in question.

2011, 2012 (resupplied for revisions to the National Mortality Database), and 2013 — Nationally, by:

• age group and sex.

2011, 2012 (resupplied for revisions to the National Mortality Database), and 2013 — state/territory of usual residence.

2011, 2012 (resupplied for revisions to the National Mortality Database), and 2013—Nationally (for states and territories with adequate identification in both hospital and deaths data), by:

• Indigenous status.

Most recent data available for 2017 National Healthcare Agreement performance reporting: 2014.

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 NSW and WA 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 across states/territories, which are likely to have an impact on administrative records and affect jurisdictional comparability.
