Summary
Parkinson's disease treatment has been revolutionised by the advent of deep brain stimulator surgery. The major benefits come from improved motor function and quality of life. We aim to test the relative benefits of two different targets for brain stimulation and compare their effects on quality of life and cognition. We will also use some of Australia's expertise in brain scanning technology to look for pre-operative predictors of treatment outcomes in this group of older patients with PD.

Summary
Waking up during surgery (awareness under anaesthesia) is a frightening reality for some patients. Although uncommon (occurring in about 1 in 1000 operations), it remains one of the main concerns of patients before their surgery. Recent studies (including our own) have demonstrated that processed EEG monitoring using bispectral index (BIS) can markedly reduce the risk of awareness. Other EEG monitors are being developed, but each have weaknesses.

Although uncommon (occurring in about 1 in 1000 operations), it remains one of the main concerns of patients before their surgery. Recent studies (including our own) have demonstrated that processed EEG monitoring using bispectral index (BIS) can markedly reduce the risk of awareness. Other EEG monitors are being developed, but each have weaknesses. As approximately two million Australians have a general anaesthetic each year, about 2000 will suffer an episode of awareness. More than 60 million people around the world have an anaesthetic, and so the problem is substantial. This suggests the potential benefits (health outcomes, commercial gains) are very great. In 2000 less than 5% of US hospitals used BIS monitoring; the current figure in the US is about 69% of the best-rated hospitals (US News and World Report) and 78% of teaching hospitals. A similar rapid growth is occurring in Australia and Europe. We are working with a successful Australian Company (Compumedics Ltd) to develop a better awareness monitor. We plan studies in groups of patients have surgery.Read moreRead less
Combined Randomised And Observational Study Of Type B Ankle Fracture Treatment

Funding Amount
$117,331.00
Summary
Ankle fractures are frequently seen in emergency departments, and isolated AO type B fibula fractures are the most common type of ankle fracture. Current treatment is equally divided between surgical, and non-surgical, as per surgeon preference. When managed surgically, these fractures consume considerable healthcare resources and expose patients to risks. This study will determine if surgery improves outcomes for patients with type B ankle fractures when compared with non-surgical management.
Creating A Culture Of Safety And Respect: A Controlled, Mixed Methods Study Of The Effectiveness Of A Behavioural Accountability Intervention To Reduce Unprofessional Behaviours

Summary
Unprofessional behaviours among health professionals are common and are associated with increased patient dissatisfaction and medicolegal risk. Addressing these behaviours is a national issue. Ethos is a structured accountability system involving a process of early, non-punitive and tiered intervention and will be introduced across four Australian hospitals. This research will be the first controlled study to assess the effectiveness of the Ethos program to improve patient safety in Australia.

Orthopaedic surgery has led to significant improvements in patient's quality of life.

SNAC1:A Randomised Trial Of Sentinel Node Based Management Versus Axillary Clearance For Women With Small Breast Cancers

National Health and Medical Research Council
Funding Amount
$1,338,436.00
Summary
SNAC1 compares two operations for assessing cancer spread to the lymph nodes in women with early breast cancer: 1) axillary clearance and 2)sentinel node biopsy. Axillary clearance involves removal of most lymph nodes in the armpit. In sentinel node biopsy only a few lymph nodes most closely related to the breast cancer are removed. The trial will determine if sentinel node biopsy reduces lymphoedema and gives equivalent cure rates. If it does, then it should become standard practice.

Most need surgery to remove the cancer and determine if it has spead to glands in the armpit (axillary lymph nodes). Knowing whether the cancer has spread to the axillary lymph nodes helps determine prognosis and plan treatment. Surgical removal is the most reliable way to assess the axillary lymph nodes. SNAC1 compares two operations for assessing cancer spread to the lymph nodes in women with early breast cancer: 1) axillary clearance and 2) sentinel node biopsy. Axillary clearance involves removal of most lymph nodes in the armpit. In sentinel node biopsy only a few lymph nodes most closely related to the breast cancer are removed. Axillary clearance is the current standard operation. However, it is associated with risks including infection, pain, stiffness, numbness and lymphoedema (arm swelling). Lymphoedema may occur in 5-50% of women treated for breast cancer and can cause major suffering and disability. In many women their breast cancer has not spread to the lymph nodes, and axillary clearance is unnecessary. Recent studies suggest sentinel node biopsy may provide as much information as axillary clearance. Scans and dye are used to help locate the sentinel nodes. Minimising the amount of surgery to the armpit should reduce the side effects. However, the long term safety and effectiveness of removing only a few nodes is unknown. The trial will determine if sentinel node biopsy reduces lymohoedema and gives equivalent cure rates. If it does, then it should become standard practice. The study complements comparable studies being done in US, UK and Europe by providing unique information about arm symptoms and quality of life. SNAC1 recruited 1,088 women in 4 years. This application is for the work needed to report on outcomes after all women have been followed for 5 years.Read moreRead less

Summary
Most cancer patients in Australia now expect and are told their cancer diagnosis. There is considerable variation in the extent to which patients are informed about treatment options and are involved in treatment decisions. It can be argued that a treatment decision should be based on the oncologist's knowledge and the patient's preference.

There is considerable variation in the extent to which patients are informed about treatment options and are involved in treatment decisions. It can be argued that a treatment decision should be based on the oncologist's knowledge and the patient's preference. Two possible models can achieve this optimal outcome: the oncologist decides treatment on the basis of information passed on to him-her from the patient (the enabled doctor), and the patient chooses treatment based on informaton provided by the doctor (the empowered patient). We have developed a booklet on 'how treatment decisions are made'. In a randomised trial, patients seeing an oncologist for the first time are given the booklet and shown a video of ' their' oncologist interviewing an actor patient. The subsequent consultation is audiotaped to study the effect of these interventions on patient and doctor behaviour. The results of this trial will inform the development of our new patient educational materials. We now plan to develop consultation preparation packages. Patients will be sent information at least 48 hours before their first appointment with an oncologist with the goal of helping patients to achieve their preferred involvement in the consultation. The complete package will contain four components : a booklet on how treatment decisions are made including an outline of the two treatment decision models, a question prompt sheet and recommendation to prepare a list of questions, a booklet on Patient Rights, and an introduction to the Cancer Centre. The effects of the total package, and of just the Cancer Centre component on patient preferences for information and involvement in medical decisions, their consultation behaviour, and patient and doctor satisfaction with decision making will be studied in a randomised trial with control patients receiving no preparatory materials.Read moreRead less
Human Factors And Patient Safety During Paediatric Heart Surgery: An Evidence-based Approach To Improve Patient Outcomes

Summary
The research project aims to improve outcomes of children undergoing repair of heart birth defects. The novel study is devised to engage health care providers in the re-design of surgical interventions to improve child outcomes. The collaborative approach of engaging health care providers and carers in the design of improvement interventions can help overcome the implementation gap and ensure rapid improvement and enhanced patient safety of children undergoing heart surgery repair.
