Urinary-Tract Infection Survey
|Team||Professor Brett Mitchell, Avondale College of Higher Education|
|Description||Urinary-tract infections occur commonly in both the community and hospital settings. In a series of studies and publications, the first such study of its kind in Australia, contemporary data on infection rates were determined and a standardised approach for surveillance was developed.|
|Impact Summary||The impact of this research is evidenced in two different ways: (1) the development of a national approach to undertaking urinary-tract infection surveillance in Australian hospitals; and (2) support for a state-wide approach to infection-prevention strategies in hospitals in New South Wales.|
BackgroundUrinary-tract infections occur commonly infection in both community and hospital settings. Approximately 8% of all patients who are admitted to a hospital acquire an infection they did not have at the tie of admission. Infections that are associated with receiving healthcare are called healthcare-associated infections. It has been estimated that 200,000 healthcare-associated infections occur each year in Australia, although these data are potentially unreliable.
Approximately 30% of healthcare-associated infections are urinary-tract infections (HAUTIs).
A large proportion of HAUTIs are associated with urinary catheter use and potentially can be prevented. HAUTIs that are associated or caused by catheter use are called catheter-associated urinary-tract infections (CAUTIs).
In our series of studies, we sought to establish the point prevalence of HAUTIs and CAUTIs in Australian hospitals, to describe the level and comprehensiveness of documentation related to care of urinary catheters, and to compare two internationally accepted definitions and approaches for surveillance of these infections in hospitals. This was the first such study of its kind in Australia, and it provided contemporary data on infection rates which in turn justified a larger study and interventions to reduce this infection.1
FocusHealthcare-associated infections; infectious diseases; preventative medicine
ImpactThis impact of this research is evidenced in two different ways: (1) the development of a national approach to undertaking urinary-tract infection surveillance in Australian hospitals; and (2) support for a state-wide approach to infection-prevention strategies in hospitals in New South Wales.
The initial study, undertaken in six Australian hospitals, demonstrated the frequency at which this infection was occurring in Australia and provided an assessment of best method for hospitals to undertake surveillance.1 This resulted in the publication of a national protocol paper to set out an agreed method for undertaking surveillance of urinary-tract infections in Australia.2 The proposed approach has since been adopted by Australian hospitals and aged-care facilities, with the researchers having provided the platform for the collecting and benchmarking of these data. The uptake from this was notable: 87 acute-care facilities and 17 aged-care facilities across four Australian jurisdictions took part in 2015.3 This is the only multi-centre hospital surveillance program available nationally that is not run by a government department.
After demonstrating the impact this infection has on patients and on the health service, a state-wide quality improvement project was developed and launched by the Clinical Excellence Commission in New South Wales. This initiative focused on preventing catheter-associated urinary-tract infections. Guidance for clinical practice is now in place and is being implemented in public hospitals across New South Wales. At the launch of this initiative, A/Prof Mitchell was an invited speaker. It is envisaged that the clinical guidelines will now also be integrated into the undergraduate nursing curriculum. The impact is enhanced by A/Prof Mitchell’s being the lead author on a national positions statement on preventing catheter-related infections5, which was incorporated into NHMRC national infection control guidelines. These guidelines are reinforced by hospital accreditation standards, specifically Standard 3, meaning they need to be followed within Australian hospitals. The importance of this work has also been recognised by the organisers of the 5th International Australasian College for Infection Prevention and Control conference held in Melbourne in 2016. At this conference, there was a concurrent session dedicated to this topic and A/Prof Mitchell was invited to address the closing plenary session in whch he argued a case for more national work in this area.
Importantly, A/ProfMitchell was invited by the New England Journal of Medicine to join an expert panel when it recently published notable research in this area. Their association with this high-profile publication demonstrates that the authors working in this field are now recognised and respected internationally.
Future DirectionThe research also led to the identification of gaps and areas for future research which has resulted in another successful grant application and two additional grants are currently under review.

The Complete Health Improvement Program (CHIP)
|Team||Dr Darren Morton, Avondale College of Higher Education
Dr Lillian Kent, Avondale College of Higher Education
Dr Paul Rankin, South Pacific Division of Seventh-day Adventists
|Description||The Complete Health Improvement Program (CHIP) is a lifestyle medicineintervention that targets chronic diseases. Members of the Lifestyle Research Centre at Avondale College of Higher Education made a major contribution to the development of CHIP and feature in the program. CHIP now operates in over 10 countries and is widely recognised as a leading community-based lifestyle intervention. The LRC is the preferred research-centre for CHIP-related studies and the centre receives data from CHIP programs conducted throughout the world. This has attracted higher-degree research students and has resulted in several international publications.|
|Impact Summary||The activities of the LRC have played an important part in CHIP’s gaining worldwide recognition. In turn, the widespread adoption of CHIP has resulted in the LRC’s playing an important role in advancing the emerging field of lifestyle medicine.
Lifestyle medicine is now championed by peak bodies in three continents and members of the LRC have been acknowledged by all three, as invited speakers at conferences, editorial board members and founding fellows.
BackgroundIn 2009 Paul Rankin commenced PhD studies at Avondale College of Higher Education, under the supervision of Dr Darren Morton. His research was focused on the outcomes achieved by a lifestyle intervention—known as the Coronary Health Improvement Project (CHIP)— that targeted chronic diseases. Rankin targeted CHIP programs in New Zealand, but a relationship was soon established with the CHIP global headquarters in the United States and he moved the site of his studies to North America. After Rankin publishing his findings in the American Journal of Cardiology, Dr Morton introduced the program to the Australian-based company, Sanitarium Health and Wellbeing . In 2011 Sanitarium purchased the global rights to the program and invited Morton and Rankin to lead the re-development of the program, which was re-named the Complete Health Improvement Program. Dr Morton also appeared as one of the three major presenters in the audio-visual program. CHIP now operates in over 10 countries and is widely recognised as one of the world’s premier community-based lifestyle medicine interventions.
In 2013 the Lifestyle Research Centre at Avondale signed a memorandum of understanding with Sanitarium, making it the preferred global research-centre for CHIP-related projects. This has led to the production of a number of research publications and has resulted in the Lifestyle Research Centre’s being viewed as a centre that has high impact.
FocusLifestyle intervention for chronic disease
ImpactWhile the activities of the LRC have played an important part in CHIP’s gaining worldwide recognition, in turn the widespread adoption of CHIP has resulted in the LRC playing an important role in advancing the emerging field of lifestyle medicine. Lifestyle medicine is now championed by peak bodies in three continents and members of the LRC have been acknowledged by all three— as invited speakers at conferences, editorial board members and as founding fellows. For example, Dr Morton has been an invited speaker at several conferences hosted by both the Australasian Society of Lifestyle Medicine and the American College of Lifestyle Medicine, and was a member of the opening panel of the 2014 American College of Lifestyle Medicine where he represented an Australasian perspective. He was also an invited keynote speaker at the Global Lifestyle Medicine Conference in November, 2016. Dr Morton has also been an invited writer and reviewer for the American Journal of Lifestyle Medicine and has been asked to serve on the editorial board of the forthcoming European-based journal titled Lifestyle Medicine.
In 2015 the LRC launched a Graduate Diploma in Lifestyle Medicine. The course has been well received and is formally recognised by the Australasian Society of Lifestyle Medicine as a preferred pathway for health professionals to gain Fellowship standing with the society.
Interest in the CHIP has resulted in collaborations with other academic institutions for grant applications, including the University of Sydney, University of Newcastle, University of Queensland and Western Sydney University. In addition, there have been two higher-degree (research) student completions that were focused on CHIP-related projects and currently there are several HDR students undertaking doctoral research.
Avondale’s LRC has gained significant momentum and impact in the Lifestyle Medicine area through its research focus on the CHIP. This is evidenced by members from the research centre being invited by the American Journal of Lifestyle Medicine to write a review of the CHIP, as well as the recognition of the postgraduate course in Lifestyle Medicine offered through the LRC by the Australasian Society of Lifestyle Medicine.
Future DirectionThe LRC has an ongoing relationship with the international CHIP effort that is expanding into other countries.

Live More – The merged Reflect/Complete Health Improvement Program (CHIP) in the South Pacific
|Team||Ms Pia Reierson, Avondale College of Higher Education
Dr Lillian Kent, Avondale College of Higher Education
Dr Darren Morton, Avondale College of Higher Education
|Description||Live More is a comprehensive community-based intervention to reduce chronic disease risk-factors and medication usage, while also addressing food security as it relates to availability, access and utilisation. Live More uses the methodology of Reflect to deliver lifestyle messages appropriate to any given local context.|
|Impact Summary||Evidence from preliminary data from the Pacific Islands has stimulated further interest by the Adventist Development and Relief Agency (ADRA) to trial the Live More program in a developing country in Asia where the Reflect methodology is widely used to address cultural issues. ADRA Cambodia has commenced a trial of the Live More program in rural and semi-rural communities in the Pursat District of Cambodia.|
BackgroundLifestyle interventions increasingly are being recognised as effective countermeasures for chronic diseases including cardio-vascular disorders and type II diabetes mellitus (T2DM). The Complete Health Improvement Program (CHIP) is a comprehensive, community-based lifestyle intervention developed in the United States and an estimated 60,000 individuals have participated in the program.
The CHIP intervention has shown benefits for the management and reversal of chronic diseases in adults of all ages and has been described by the American College of Lifestyle Medicine as “achieving some of the most impressive clinical outcomes published in the literature” (source of quote) The clinical effectiveness of CHIP has been documented in over 25 peer-reviewed publications in medical and scientific academic journals.
The Adventist Disaster and Relief Agency (ADRA Australia) recognized the strengths of the Complete Health Improvement Program (CHIP) in its holistic approach to providing education that can prevent and reverse chronic disease, supported by strong evidence-based research and documentation evaluating the effectiveness of the program.
However, given the local context of the countries where they work, it is to be expected that the current program would face some challenges in working with the rural and most marginalised parts of some of the low- to medium-income countries:
- The text book and resource material requires that the participants need to be literate in order to take full advantage of the program;
- The education program requires that the participants are reasonably fluent in English;
- The resource material requires technical equipment and electricity;
- The ingredients of the suggested recipes may not be available locally;
- The examples and ‘culture’ of the visuals may seem foreign/ difficult to identify with.ADRA Australia therefore invited a research team from Avondale College of Higher Education to collaborate on the development of a community model of CHIP that combines good community- development practices with the CHIP messages.
The new and adaptive approach combines community development/literacy and numeracy (using Reflect) with a modified version of the CHIP messages appropriate to any given local context. The model also focuses more widely on food security and addresses availability, access and utilisation.
Reflect is an approach to learning and social change, and key to the Reflect approach is the creation of a space in which people feel comfortable to meet and discuss issues relevant to them and to their lives. Reflect is being used on a small scale (in single communities) and on a large scale (with thousands of communities), by over 350 organisations. It is used by local, national and international NGOs, by social movements, people’s organisations, and district and regional governments.
Reflect aims to improve the meaningful participation of people in decisions that affect their lives, through strengthening their ability to communicate. It begins with respect and value for people’s existing knowledge and experience and involves a continual cycle of reflection and action. It is not about reflection or learning for the sake of it, but rather reflection for the purpose of change. Since the inability to communicate is both a cause and effect of inequitable power relationships, Reflect employs a wide range of participatory tools to help create an open or democratic environment in which everyone is able to contribute.
In the short term, ADRA Australia is partnering with Avondale College of Higher Education as well as ADRA offices and the Seventh-day Adventist Church in the South Pacific to pilot implementation of a community model of CHIP across three countries in the South Pacific.
FocusThe outcomes of the study may provide evidence that a modified and contextualised CHIP can be used in the South Pacific to improve health and well-being. It will also provide evidence that when merged with Reflect, social change will provide for more equitable societies in which all participants are empowered.
ImpactEvidence from preliminary data from the Pacific Islands has stimulated more interest by ADRA to trial the Live More program in a third world country in Asia where the Reflect methodology is widely used to address cultural issues. ADRA Cambodia has commenced trialling the Live More program in rural and semi-rural communities in the Pursat District of Cambodia.
The first publication from this research is currently under review by an refereed journal.
Future DirectionThis pilot may also provide ADRA with evidence that a viable, well researched, platform for rolling out a community version of CHIP across a broader range of countries within 3-5 years. The ADRA International President endorses/supports the plans, and this high level endorsement within the Network may enable the potential global scale implementation of a community model CHIP across a broad range of third world countries, including those in South America, Africa, Asia, as well as Australian Aboriginal and Torres Strait communities.

Testing a predictive model of family functioning and psychological distress in family caregivers supporting relatives with severe traumatic brain injury

|Description||A series of investigations were conducted to test a contemporary model of psychological distress in family caregivers of individuals with traumatic brain injury (TBI). The results showed that cognitive and behavioural impairments significantly disrupted family functioning, which in turn increased psychological distress in caregivers. The results have assisted the team to improve targeting of family support interventions.|
|Impact Summary||The team has made unique and innovative contributions to the brain-injury rehabilitation field by being the first to develop a contemporary model of psychological distress in family caregivers of individuals with TBI, and to test the model using structural equation modelling (SEM) techniques. They are the only researchers in the field to have examined the experiences of male family members and the experiences of parental dyads.|
BackgroundIt is widely recognised that families play a critical role in maximising the recovery and long- term community re-integration of people with TBI. However, families face many practical, emotional and relational challenges as they seek to adjust to the trauma of an injured relative, and to having to adopt a carer role. Increasing our understanding of the factors that cause these challenges will enable services to provide more-effective support, with important flow-on benefits to the person with TBI.
Concern has also been expressed about the limited use of explicit conceptual frameworks to study family functioning after TBI. Subsequently, in a series of studies the team used Structural Equation modelling (SEM) to test a conceptual model synthesised from the Conservation of Resources Theory, the McMaster Model of Family Functioning, and Elliott and Eisdorfer’s normative perspective of stress, to understand the interactional effect of TBI on families.
Collectively, the results of our studies supported the model and showed that cognitive and behavioural impairments significantly disrupted family functioning, which in turn increased psychological distress in caregivers. More specifically, for spouses multi-group analysis showed cognitive and behavioural impairments significantly disrupted family functioning, which in turn increased psychological distress. In contrast, cognitive and behavioural impairments did not significantly disrupt family functioning in parents. For parents, however, cognitive impairments increased psychological distress. The effect of cognitive impairments statistically was more influential on the level of distress in parents when compared to the levels experienced by spouses. Our research showed that disrupted family functioning was more influential on the level of distress in male caregivers than in female caregivers.
FocusTraumatic brain injury; family functioning; caregiver; psychological distress
ImpactFour innovative and unique contributions to the field have resulted from this research:
- At a theoretical level, the team are the first to synthesise Stress theory and Family Systems theory to develop an explanatory model that accounts for the psychological distress of family members supporting a relative with TBI;
- At the methodological level, the team pioneered the application of advanced multivariate statistical techniques to research the area of family adaptation to TBI;
- The team is the first group of researchers to use SEM to test many of the hypothesised pathways between neurobehavioural impairment, family functioning and relative distress;
- The team has been the first to use Multi-group analysis (an application of SEM) to investigate the various challenges faced by different kinships groups (parents and spouses)
- Distinguished between experiences of male family-members (the first to do so—previous research has typically focused only on female family-members) and documented the experiences of parental dyads (previous research has typically focused on only one family-member);
- Highlighted the potential role that spouse support-groups could play;
- Underlined the importance of using measures with sex-based population norms when assessing psychological distress among family-members;
- Demonstrated the value of programmes that provide family/ relationship counselling or training for spouses in the knowledge and skills to manage and minimize the impact of behavioural and cognitive impairments can be a useful adjunct to the provision of counselling
- Demonstrated that since a proportion of prime caregivers are male, family-support strategies need to cater for both commonalities and differences in caregivers of both genders.
Future DirectionA paradigm-shift is currently underway in neurorehabilitation toward a new emphasis on caregiver resilience. This is worthy of more investigation in the context of caregivers of people with TBI. To address this issue, Associate Professor Simpson and Dr Anderson have commenced testing a predictive model of resilience among family caregivers supporting relatives with TBI. The aim of this investigation is to provide a new understanding of the nature and process of caregiver resilience when a relative sustains a TBI and provide the platform for future large-scale intervention studies.
