Current Prevention ‘System’
Reflects the broader health system Fragmented Loosely coordinated Multiple and discontinuous funding sources
Largely communicable disease focussed Largely health system focussed Poor Continuity of Effort

General Strategies
1. Shared responsibility – developing strategic partnerships
2. Act early and throughout life
3. Engage communities
4. Influence markets and develop connected and coherent policies
5. Reduce inequity through targeting disadvantage
6. Indigenous Australians – contribute to ‘Close the Gap’
7. Refocus primary healthcare towards prevention

Health System and Prevention
What can the health system do to better prevent disease and promote health?
Questions of Effectiveness and Efficiency in Health System Prevention Action
Individual, Group, Community, Population focus
How much Health $$ should be spent on Prevention?
What does Health control and regulate?

Scenario Testing
1. An individualistic, market-driven society that adopts a more long-term and sustainable view.
2. A society where social responsibilities are prioritised, and communities and Government implement plans to meet long-term challenges.
3. A society where communities take the lead and focus on tackling difficulties as they arise.
4. An individualistic, market-driven society that reacts to problems when and where they occur.

Systems Thinking about doing Prevention
![Page 28: System Perspectives on Prevention](https://reader036.fdocuments.net/reader036/viewer/2022070405/56813f33550346895da9d92d/html5/thumbnails/28.jpg)
Complex Systems and Wicked Problems
No easy fix, no one strategy. Likely to be lots of “failures”, need to learn from failures as
well successes. Need systematic and systemic approaches. Need persistence – how do we institutionalise ongoing
action? Need to assess and minimise the potential for harm along
the way.
![Page 29: System Perspectives on Prevention](https://reader036.fdocuments.net/reader036/viewer/2022070405/56813f33550346895da9d92d/html5/thumbnails/29.jpg)
The Ways of a Systems Thinker
Sees the whole picture Changes perspectives to see new
leverage points in complex systems Looks for interdependencies Considers how mental models create
our futures Pays attention and gives voice to the
long-term “Goes wide” (uses peripheral vision) to
see complex cause and effect relationships
Finds where unanticipated consequences emerge
Sees oneself as part of, not outside, the system

What does this mean?
Understand the Problem and Context (Diagnostic) Identify Intervention Points and Options Identify Potential Impact
(Effectiveness, Risks, Equity, Benefit-Cost) Identify Potential Achievability under Different Settings
(Political, Investment Level, Scaling, Dose) Understand the Players and Interactions Implement, Learn, Change
(understanding, action, outcomes)

Research Opportunities
The Value of Prevention How do we value prevention rather then health care
avoidance? How do we communicate that value to the
community and decision makers? System Perspectives
How can we better implement what we know works in prevention? Learning from Doing.
Why doesn’t it work they way we think it should in real life?

Research Opportunities
The Prevention System What are the elements of successful prevention
system(s)? What are the options for prevention – individual,
community, population – programs, regulation, legislation?
Driving Change How do we become more effective influencers? Consumerism, choice and the prevention paradox?
