This project, analyses detailed epidemiological, service utilisation and costing information on a range of heart and associated chronic disease in Aboriginal Western Australians.  Through engagement with various Western Australian Aboriginal planning forums, policy makers, health service managers, non-governmental organisations and funders, this project aims to increase stakeholder understanding of the evidence to facilitate changes that  improve Aboriginal heart health. 

Aboriginal people have a life expectancy 10-14 years shorter than non-Aboriginal Australians, with cardiovascular diseases explaining 23% of the differential in disease burden. Cardiovascular disease disparities are reflected in substantially higher Aboriginal mortality and hospitalisation rates, as well as high prevalence of classical risk factors for cardiovascular disease.  Additionally, there are limited reliable estimates of health service utilisation and health costs relating to cardiovascular diseases in Aboriginal people.

This project is being undertaken by researchers from the Western Australian Centre for Rural Health (WACRH) and the Cardiovascular Research Group in the School of Population and Global Health, with the engagement of a wide network of stakeholders in Western Australia.  Originally supported by two previous NHMRC grants, researchers continue to work on this data to answer important research questions related to cardiovascular disease disparities in health burden, service provision and utilisation.

 Further information can be found on the WACRH site.

Project aims

  1. To describe and compare the epidemiology and clinical manifestations of coronary heart disease (CHD), chronic heart failure (CHF), dysrhythmias and major co-morbid conditions including diabetes and chronic kidney disease (CKD) in Aboriginal and non-Aboriginal people in WA.
  2. To compare (using hospitalisation data) access of Aboriginal and non-Aboriginal people to acute and continuing medical care for heart diseases, focussing on acute and chronic CHD, CHF and cardiac dysrhythmias.
  3. To describe health care service utilisation and direct costs for heart diseases in Aboriginal and non-Aboriginal people in WA as the basis for future studies of cost-effectiveness of public health and clinical interventions to improve cardiovascular health in Aboriginal people.
  4. To investigate the responses of health decision-makers to epidemiological and cost information about Aboriginal inequalities in CHD care and outcomes.  This component incorporates dissemination of findings and studying barriers within the system around research translation.
