This visualisation tool was developed in a collaboration between Curtin University’s National Drug Research Institute (NDRI) and University of Victoria’s Canadian Institute for Substance Use Research (CISUR) and is maintained and regularly updated by NDRI.
It was developed as a component of the National Alcohol Indicators Project (NAIP) (Principal Investigator: Prof Tanya Chikritzhs; Chief Investigator: Dr William Gilmore; Project Staff: Paul Jones), a project federally funded and coordinated by NDRI since 1999, aimed at tracking and reporting on local, state/territory and national trends in alcohol-attributable harm across Australia.
Wholly and partially alcohol-attributable
The tool presents trends and patterns in hospitalisations and deaths for wholly (i.e. 100% alcohol caused) and partially (i.e. fractionally alcohol caused) alcohol-attributable conditions (see Box 1). For death data this is based on the underlying cause of death, and for hospitalisation data this is based on either primary diagnosis or external cause.
Wholly = Alcoholic liver cirrhosis etc.
1 alcoholic liver cirrhosis (K70) death = 1 wholly alcohol-attributable digestive disease death
Partially = Falls, assaults, chronic pancreatitis etc.
1 assault injury (X85-X89.9; Y00-Y09.9; Y87.1) hospitalisation = 0.15 partially alcohol-attributable intentional injury hospitalisation.
The tool presents 'net' totals by adjusting for apparent protective effects of alcohol at low dose (i.e. deaths or hospitalisations avoided) for cardiovascular, digestive and endocrine conditions.
100 partially alcohol-attributable ischaemic stroke deaths + 50 partially alcohol-attributable ischaemic stroke deaths avoided (i.e. minus 50 deaths) = 50 ‘net’ partially alcohol-attributable cardiovascular disease deaths
Calculating partially alcohol-attributable fractions
Australia-specific alcohol-attributable fractions for all partially alcohol-attributable health conditions by age and sex were calculated in an open access online alcohol harm estimator (International Model of Alcohol Harms and Policies, InterMAHP v2.1) with detailed methods described there [1,2].
Alcohol-attributable fractions from previous NAIP publications, using data sources deemed more applicable to the Australian population, superseded those calculated in InterMAHP for road traffic crash injury (pedestrians and non-pedestrians), intentional self-harm injury, assault injury (0-14 age group). Stomach cancer is an addition that had not been included in InterMAHP.
The protective effects of alcohol at low dose for Ischaemic heart disease, Haemorrhagic stroke, Ischaemic stroke (within Cardiovascular diseases group), Acute pancreatitis (within Digestive diseases group) and Diabetes Type 2 (within Endocrine conditions group) have been applied to the data and results in deaths or hospitalisations avoided. For Ischaemic heart disease we followed the Roerecke and Rehm option in InterMAHP [1,2] that has the greatest protective effect and produces the most conservative estimates of overall alcohol-attributable harm.

De-identified unit record hospitalisation data were requested and provided by the Australian Institute of Health and Welfare from the National Hospital Morbidity Database.
De-identified unit record death data were provided by the Australian Coordinating Registry (ACR) at the Queensland Registry of Births, Deaths and Marriages who act on behalf of the custodians of the data, which include staff in the eight jurisdictional Registries of Births, Deaths and Marriages, eight jurisdictional Coroners and the National Coronial Information System.
Estimated Resident Population data for calculating rates were sourced from the Australian Bureau of Statistics.
Per capita alcohol consumption data and alcohol consumption pattern data used in calculating alcohol-attributable fractions were sourced from the Australian Bureau of Statistics (Apparent Consumption of Alcohol, Australia) and Australian Institute of Health and Welfare (National Drug Strategy Household Survey) respectively.
Counts and rates
Counts of alcohol-attributable hospitalisations and deaths have been included for transparency and for use by others but should not be used for direct comparison between years, states/territories, region types, sexes or age groups due to changes and differences in the underlying population at risk.
Age-specific (15-34, 35-64, 65+) and directly age-standardised rates (calculated for the All (15+) category only) allow for better comparison of overall rates between states/territories, by adjusting for their different age structures.
In the hospitalisation data, ‘Year’ is the financial year of the hospital separation e.g. 2020 is FY2019/20. In the death data, ‘Year’ is the calendar year of death registration.
State/territory and Region type
In the hospitalisation data, both ‘State/territory’ and ‘Region type’ are based on place of residence except for 2014-2018 when ‘State/territory’ is the state/territory of hospitalisation. We don’t expect this to affect the trends as inhouse analyses found 98% of 2010 hospitalisations were in the state/territory of ‘residence’. In the death data, both ‘State/territory’ and ‘Region type’ are based on place of residence.
Metro and Non-metro areas are defined differently for hospitalisations (using ABS Remoteness Areas classification) and deaths (using ABS Greater Capital City Statistical Areas). In both hospitalisation and death data the Australian Capital Territory has been classified as Metro only and the Northern Territory and Tasmania have been classified as Non-metro only. Due to some unit records missing sub-state residence information, ‘Metro’ plus ‘Non-metro’ counts do not always equal ‘All’.
We excluded records where state/territory was either an overseas territory or missing.
Health conditions related to the impacts of maternal consumption on the foetus, such as foetal alcohol spectrum disorder, have been excluded from this analysis. Counts of these conditions are low in hospitalisation and death data and would need to be suppressed for confidentiality reasons. They are also likely to be an underestimate due to difficulties in diagnosis.
We excluded records where sex was either ‘Other’ or missing as this prevented calculation of attributable fractions and calculation of population rates.
The data presented is for Australian ‘adults’ aged 15 years and over, except in the case of Assault injury (within intentional injuries group) where we have included data for the 0 to 14 age group.
We excluded records where age was missing as this prevented calculation of attributable fractions and calculation of population rates.
Combinations where the actual hospitalisation or death counts (before alcohol-attributable fractions applied) are less than or equal to 5 are suppressed for confidentiality reasons.
Death data (2012-2020) were preliminary at time of data request, and so our results may underreport alcohol-attributable deaths where cause of death was not confirmed until a coronial inquiry was completed.
Comparisons with previous NAIP publications
Due to continuing revisions in data sources and updated methods of estimating attributable fractions, comparisons with figures released in previous NAIP publications should be done with a high degree of caution. The data in the current online version of the tool should be taken as the latest estimates.
