Supporting consumer decision making
Our consumer-focussed projects aim to comply with International Standards for Patient Decision Aids (IPDAS). Our group members participated in the international collaboration that developed these standards. Our screening decision aids aim to be consistent with our article in the British Medical Journal (BMJ) in 2004 and our paper in the Journal of the American Medical Association (JAMA) in 1999.

In a randomised controlled trial the effect of a formal advanced care planning intervention on the documentation of incurable cancer patients wishes, compliance with known end of life wishes and the quality of death are being evaluated. The intervention aims to promote discussion between patient and carer and the health care team about life expectancy and end of life issues and to promote documentation of the patient's preferences for continuing and end of life care which will be countersigned by the oncologist.

This study follows on from an RCT which trained standardised patients to ask three questions (based on the framework from Smart Health Choices). The questions significantly increased shared decision-making and the Ask, Share, Know study has successfully trained real consumers to ask these questions through watching a four minute video in the waiting room. Links to the www.askshareknow.com.au website have been requested and adopted by consumer and healthcare groups including the Consumers Health Forum of Australia, Arthritis Australia, Health Consumers Alliance of South Australia.

This project is investigating how GPs and patients make decisions about cardiovascular disease (CVD) prevention, through either lifestyle change or the use of preventive medication. Current guidelines advocate decision making based on absolute risk thresholds - the probability of a cardiovascular event over a period of time, based on multiple risk factors. However, the use of absolute risk assessment in practice is limited, GPs find it difficult to explain to patients, and patients may prefer a different approach to what is recommended in the guidelines. This research aims to determine the factors that are important to GPs and patients when deciding about CVD risk management, in order to identify ways in which CVD prevention might be improved. This research will examine role of risk communication in SDM, and the cognitive mechanisms underlying the effect of SDM interventions, such as decision aids.

Empowering patients to obtain preferred information about prognosis and end of life issues, and to be involved in advanced care planning
This study is testing the efficacy of a nurse-led intervention to introduce a question prompt list and encourage question asking about prognosis, end of life issues and advanced care planning in Oncology patients estimated to have less than 1 year to live. This is a randomized controlled trial being conducted in multiple centres in NSW. The primary endpoint is patient self efficacy in asking questions about the end of life, secondary endpoints include questions asked in the next oncology consultation; whether an advanced care plan is put in place, care at the end of life, and bereaved carers’ perceptions about the patient’s quality of death.

This research aims to understand and improve communication between patients, caregivers and health professionals regarding challenging topics including life expectancy and goals and preferences for care at the end-of-life. The communication support intervention aims promote such discussions early in the final year of life, in concert with consideration of further chemotherapy, radiotherapy or surgery and prior to crisis admission to palliative care. By enhancing and normalising communication about these issues, this research hopes to promote shared decision-making and knowledge about care goals and treatments between patients, caregivers and oncologists. Through enhanced end-of-life communication, particularly with regards to Advanced Care Planning, this research aims to improve quality-of-life at the end-of-life and reduce futile care measures and caregiver burden.

Myelodysplastic syndromes are complex and hard to explain or understand. This research is piloting a question prompt list for patients and their families. In the first stage, we are seeking patients’ feedback on a draft QPL, and measuring their information needs and preferences for involvement in decision making. This study will be conducted in France and Australia through patient support group organisations.

Using an experimental design we are investigating the impact of presenting young women (aged 18-25) information about overdiagnosis and overtreatment in cervical screening and are comparing this to a non-cancer screening example. The primary outcome is intention to screen and secondary outcomes include decisional conflict, attitudes to screening, understanding and measures of perceived risk and worry about cancer. This work is examining how provided information to support shared decision making in cervical screening for young women, impacts decisions and psychosocial outcomes.

This research looks at shared decision-making among older adults and their clinicians. The case for shared decision-making among older adults is particularly strong for several reasons. Decision-making for this group is often very complicated, it involves the weighting of many different factors, and there is lack of clinical evidence to base decisions on. To add, heterogeneity increases with age and older adults’ preferences will vary widely depending on for example their frailty, level of education, cognitive and health status. The decision-making process therefore needs to be highly individualized.

This project is funded by Sydney Catalyst to develop and pilot test a decision for people aged 50-59 years considering low-dose aspirin. It seeks to translate the emerging evidence on the benefits of aspirin for prevention of cancer (particularly GI) in addition to cardiovascular disease. However, this needs to be traded off against an increased risk of bleeding and such decisions should be personalised according to patient’s clinical profiles and preferences. We are seeking funding for an RCT to test the efficacy of this tool.

The effectiveness of smoking cessation apps will be soon examined in a new project that is planned to start in July 2013. The project will compare standard smoking cessation method (information only) with a decision making method, plus will follow up the result of the decision in the long term and will also monitor decision changes over the follow up period. Although this study involves some shared decision making in the intervention group, we are not currently looking at shared decision making as main outcome. However, the outcomes of decisions that involve shared decision making are documented to be analysed.

In this study we have conducted a systematic review on triadic communication, interviewed oncologists, patients and carers about the role of carers in consultations, and their experience of communication in this setting, developed a coding system of triadic communication and have compared audiotaped oncology consultations with and without a 3rd party (family) on communication and decision-making behaviours.
We now plan to develop a framework for triadic decision making, guidelines, and training for oncologists and patients/carers in triadic decision making (pending funding).

Understanding and improving cancer communication and decision making among patients with low education and literacy
Patients with cancer are increasingly expected to process complex medical information and make decisions about their treatment and follow-up care. There is growing concern that many patients do not have the health literacy skills to do this effectively. While there have been major advances to inform and involve patients with cancer in treatment decision making, there has been little research with patients who have lower health literacy. This is an important group who have limited health knowledge and experience poorer health outcomes. Our aim is to identify ways to improve patient understanding and involvement in cancer consultations, particularly among patients with low health literacy. This study has 3 components: 1) interviewing health professionals about health literacy; 2) Screening and interviewing patients of lower health literacy; 3) Audio recording consultations between radiation oncologists and patients.
1) This project involves qualitative interviews with radiation oncologists, radiation therapists and radiation oncology nurses involved in the care of people receiving radiotherapy as treatment for cancer. Participants are interviewed about their experiences communicating with people of lower health literacy levels and its impact on treatment and follow-up care. The findings from this project will provide important evidence about how to optimise communication to and decision-making by radiotherapy patients with lower health literacy skills.
2) We are screening health literacy levels of patients attending for radiotherapy treatment and interviewing those of lower literacy levels about their experience of preparing for treatment.
3) Audio recording consultations between patients and their radiation oncologist to explore how their communication may be influenced by the patient's health literacy level.
