METEOR identifier: | 657092 |
Registration status: | Health, Standard 17/08/2017 |
Description: | Rates of hospitalisation for cardiac conditions, by Aboriginal and Torres Strait Islander status. |
Rationale: | In addition to the 5 priority areas, the Better Cardiac Care project also includes 2 summary measures, which are designed to monitor hospitalisations from cardiac conditions (measure 6.1—that is, this measure) and mortality from cardiac conditions (measure 6.2). These measures, which provide a population-wide perspective on the impact of cardiac conditions over time, are broad indicators of the effectiveness of early risk assessment and preventative care. |

Computation description: | The number of hospitalisations for cardiac conditions, divided by the estimated population, and multiplied by 1,000. Age-standardised rates are calculated for comparisons between Indigenous and non-Indigenous Australians, and for analysis of change over time. Presentation: Hospitalisations per 1,000 population. Definitions: Hospitalisation (separation)—an episode of care for an admitted patient that can be a total hospital stay (from admission to discharge, transfer or death) or a portion of a hospital stay beginning or ending in a change of care type (for example, from acute care to palliative care). Cardiac condition—separations with a principal diagnosis of ICD–10–AM (8th edn.) codes I00–I52, which includes acute rheumatic fever (ARF), chronic rheumatic heart diseases (RHDs), hypertensive diseases, ischaemic heart diseases, pulmonary heart disease and diseases of pulmonary circulation, and other forms of heart disease. |

Computation: | (Numerator ÷ Denominator) x 1,000 Age-standardised rate: calculated using the direct method, and the Australian standard population as at 30 June 2001. |
Numerator: | Number of admitted patient separations in the reference period with a principal diagnosis of a cardiac condition, excluding separations with a care type of Newborn that did not include qualified days. |
Numerator data elements: | |
Denominator: | Estimated population at the middle of the reference period. Where numerator data pertain to a single financial year, the denominator is the estimated population at 31 December, calculated from the average of the populations at 30 June at the beginning and end of the financial year. Where numerator data are summed across multiple years, the denominator is calculated by summing the mid-point population data for the relevant years. |

Comments: | General: The data for this measure are drawn from the Australian Institute of Health and Welfare (AIHW) NHMD. For 2016 reporting, the most recent data available are for 2013–14. With the exception of time trends, data are reported for the 3-year period 2011–14 to enable for disaggregation of the data by the variables of interest. Single year data are reported for the time trend analysis. Data reported for this measure are a count of hospitalisations for cardiac conditions. It is not a count of individuals because some of the hospitalisations would represent transfers for ongoing care or hospitalisations of 1 individual at different times of the year. It is also not a count of cardiac events such as ST-segment-elevation myocardial infarctions (STEMIs) because the diagnosis codes used were for the full range of cardiac conditions, rather than just those for events such as STEMIs. This differs from the approach used for Priority 3 measures (measures 3.1, 3.3 and 3.5) in which data relate to hospitalised events, which were estimated by only using diagnosis codes for specific cardiac events and by excluding hospitalisations ending in transfer to another acute hospital. Indigenous identification: While there is some under-identification of Indigenous Australians in the NHMD, data for all states and territories are considered to have adequate Indigenous identification from 2010–11 onwards (AIHW 2013). Time series comparisons are based on data for the 6 jurisdictions that were assessed by the AIHW as having adequate identification of Indigenous hospitalisations from 2004–05 onwards—namely, New South Wales, Victoria, Queensland, Western Australia, South Australia and public hospitals in the Northern Territory (AIHW 2010). These 6 jurisdictions represent about 95% of the Australian Indigenous population (AIHW 2015b). |
