Dementia in Australia

Key statistics 

Australia’s response to dementia requires economic investment across the health, aged care and welfare sectors. This investment includes expenditure associated with: diagnosis, treatment and care of people with dementia (including supporting a workforce of trained professionals); and support services for people with dementia and their informal carers.

The following pages present direct expenditure estimates for caring for people with dementia across the health and aged care sectors in 2018–19. It includes the estimated expenditure on:

• aged care services – including aged care assessments, community-based and residential aged care services
• health services – including hospital services and out–of–hospital medical services such as general practitioner (GP) and other medical specialist services, diagnostic services, allied health services and medications
• dementia support services.

Refer to the Expenditure data tables for the underlying data presented in these pages. 

The year 2018–19 is presented as this is the latest year of data available from the AIHW Disease Expenditure Database. In this report we focus on presenting health and aged care expenditure estimates that are directly attributable to dementia (rather than all costs for people with dementia), to avoid including expenditure related to other conditions. Our estimates have been adjusted to reflect the contribution of comorbidities to the costs for treatment and care of people with dementia and do not include estimates of indirect expenditure such as costs arising from the social and economic burden on carers and family, or from lost wages and productivity. More information on the methodology and data sources used to estimate expenditure directly attributable to dementia can be found by expanding the box Information sources and coverage of dementia expenditure estimates.

Total estimated expenditure on dementia

It is estimated that almost $3.0 billion of the total direct health and aged care system expenditure in 2018–19 was directly attributable to the diagnosis, treatment and care of people with dementia.

The health and aged care system expenditure directly attributable to dementia was mainly for:

• residential aged care services – $1.7 billion or 56% of the total direct health and aged care system expenditure for dementia
• community-based aged care services – just under $596 million or 20%
  • Home Care Packages, Commonwealth Home Support Programme (excluding respite care), Veterans’ Home Care Program and DVA Community Nursing program
• hospital services – almost $383 million or 13%
  • public and private admitted patient hospital care, public hospital outpatient clinics and public hospital emergency department care
• community-based and residential respite care – $133 million or 4.4%
• out-of-hospital medical services – $99.2 million or 3.3%
• dementia support programs and initiatives – $50.6 million or 1.7% (Figure 14.1).

The health and aged care expenditure estimates above reflect costs that are thought to be directly attributable to dementia and therefore they do not include expenditure related to other conditions. However, it is important to recognise that many people have co-existing conditions, some of which may be directly associated with dementia. In addition, dementia is often the main reason for people using certain health and aged care services, particularly residential aged care. For example, the estimated costs of care related to managing co-existing conditions in people with dementia who are living in residential aged care totals $6.8 billion. If these costs were included, the total direct health and aged care system expenditure for people with dementia (rather than directly attributable to dementia) would be $9.8 billion.
