Background to Study• Continuation of Masters Degree topic which investigated the factors that

influence South Australian Baby Boomers to either create or not create an advance directive.

• The PhD investigates whether interventions in the online environment can facilitate advance directive completions by South Australian Baby Boomers and comprises 3 projects which inform each other.– Systematic Review on the effectiveness of online advance directives– Health Omnibus Survey (HOS) in South Australia to determine current

prevalence rates of advance directive and computer use and comfort– Intervention study to test whether online knowledge and/or reminders can

increase completion rates of advance directives in South Australian Baby Boomers.

This presentation focuses on some of the data from the HOS survey(Ethics approval by Flinders University Social and Behavioural Research Ethics Committee)

Prevalence Rates for Learning More about ADs

ConclusionResults of this survey have identified:• More participants in this survey completed a Will than

any other instrument• Of the true advance directives, more participants

completed a Power of Attorney than the healthcare and value or choice instruments

• The age group which most frequently assisted others with these documents was aged 45-64.

• A low percentage of participants engaged in decision-making under a formal POA or POG

• Majority of participants are interested in learning more about advance directives.

Some things we haven’t discussed

• The affect of other sociodemographic characteristics on completion rates, e.g. gender, education, wealth, occupation, marital status

• Which documents were completed singularly or together, e.g. POA + POG, POA only

• The format that most people would prefer to learn about ADs, e.g. online, face-to-face, telephone or other
