The SNAPPs approach we use to address common risk

factors for chronic conditions

• Smoking

• Nutrition

• Alcohol

• Physical Activity

• Psychosocial

The challenge:Prevention strategies that

WORK at the Psychosocial level

Without taking the “PS” and socio- economic factors into account, strategies that focus on individual behavioural change probably won’t work, and even environmental measures will be less effective

What are we

to do about SNAPPs, and what still needs to happen?

Do health providers always ask their clients how many cigs they smoke, and advise them to quit?

In the modern era we have better solutions …

…..Sanitised tape worms!

We have to create supportive environments

Prevalence and consequence of Malnutrition in older people

• Malnutrition is common among elderly

• Malnutrition may lead to :– Higher risks of infection– Slow wound healing – Longer hospital stays– Poorer longer term health outcomes– Poor quality of life

Capacity Building

Healthy Settings

Community Development

Quality Improvements

The Action Steps of Mature Tastes Step 1: Use planning tool to identify, prioritise and plan to address key nutrition issues.

Step 2: HACC services action priorities.

Staff training Health PromotionNutrition Policy

Nutrition Screening

Menu changes

Step 3: Evaluation and further planning.

Some questions

• How would your service identify whether older patients were malnourished or at risk of malnutrition?

• Do you know whether malnutrition in your service’s older patients will be prevented by the care they receive when you discharge them?

And now we come to “A”, for

Alcohol….

We’ve come a long way…

Alcohol Related Harms

• Alcohol responsible for 4% of the global burden of disease (WHO)

• Alcohol causally related to 60 different medical conditions (Ridolfo & Stephenson)

• Alcohol causally related to a range of injuries, other social harms as well as hospital admissions

• As population consumption increases, harm also increases correspondingly

Tasmanian Population Response

• Under development – watch this space

• Establish a monitoring system allowing analysis of alcohol related trends

• Explore legislative change in support of safer drinking environments

• Focus on availability and marketing issues as a harm reduction measure

Tasmanian Targeted Response

• Focus on adult drinking as well as that of youth

• Strategies to build resilience in early childhood

• Strategies to address Foetal Alcohol Syndrome Disorder

• Explore introduction of workplace strategies

How does socio-economic status affect alcohol consumption?

“P” is for Physical Activity…

Live Life Get Moving: Tasmanian Physical Activity Plan 2005 -2010

• Premier’s Physical Activity Council• Four action areas/goals:

– Participation– People– Policy– Places

• Coordinated action required across all 4 areas and across sectors

Some projects and strategies– Evidence-informed social marketing campaigns – Get Active program– Move Well Eat Well (Schools)– Good Fuel for Police (DHHS will be next!...)– ‘Healthy community framework’ for local

communities– Guideline development around land use planning

and the “Healthy By Design” Guidelines (PPAC and Heart Foundation)

– Monitoring and surveillance (major deficiency).

How do health services ensure that physical activity is seen as part of treatment?

Recent national events & Prevention

Summary

• To get good traction with prevention, strong Government intervention is needed….

…and bold interventions in the marketplace are called for…

Thank you for your time

What we don’t want DHHS to do for its clients?

The continuum of prevention and care

• Primary Prevention: protection of health by measures that eliminate or reduce the causes or determinants of departures from good health, control exposure to risk, and promote factors that are protective of health.

• Secondary Prevention: early detection of asymptomatic biological changes or asymptomatic disease, and prompt and effective intervention to address these departures from good health.

• Tertiary Prevention: measures to reduce or eliminate long-term impairments, disabilities and complications from established disease and prevent or delay subsequent events.

Supporting people with chronic conditions to change behaviour

• It is relatively easy to identify the risks that will increase a persons likelihood of developing a chronic disease, but working with people to change these risk factors is a challenge faced by all health practitioners.

• Easy to call it “Non compliance” … or are different tactics required?– Self management has been identified as an

essential key element in health systems that effectively address chronic disease

Self management

• Uses principles of both health promotion and risk reduction

• The person is at the centre of their own health care

• Builds skills and confidence

• Enhanced by supportive communities and health care providers

• Involves all levels of the health system

Supporting people to manage their own risk factors and chronic conditions

• Health Practitioners:– New skills to integrate into practice: Health coaching, Mentoring;

Flinders Partners in Health Tools to assess client’s self management skills

• For clients:– Community based programs: Stanford Chronic Disease Self

management Program; Condition specific education classes; peer led Diabetes cooking classes, exercise groups;

• For the System:– A coordinated model of care that supports clients to manage their

condition in partnership with health practitioners: i.e. the Chronic care Model

• Policy Level:– National Chronic Disease Strategy– Tasmanian Health Plan: Primary Health Care services

Prevention is not merely proactively applying a disease

model to what we do
