I am a social epidemiologist and health services researcher who has been working in higher education for more than ten years. I have conducted extensive research in aged care, person-centered dementia care, health beliefs and behaviours, person-centered interactions, health and social services structuring. The major focus of my research is to improve physical and intellectual capacity of disadvantaged people through public health interventions. To do this, I use theoretical knowledge and methodological skills and experience [quantitative and qualitative] in leading and managing health and well-being research projects in different regions of Australia. I have expertise and experience in systematic, meta-analysis, scoping and integrated literature reviews and using research software such as REDCap, Qualtrics, SPSS and NVivo add value to my research data management skills and analysis capacity.
I have been a Co-investigator and Associate Investigator of two national research projects [$3.2 million], funded by Australian Department of Health, (i) Harmony in the Bush: A Personalised Model of Care for Dementia [Chief Investigator/AUD 1.5 Million]; (ii) Virtual Dementia Friendly Rural Communities [Project Coordinator/Associate Investigator – South Australia/AUD 1.7 million].

Objectives. We aimed to estimate the prevalence of reported symptoms and comorbidities, and investigate the factors associated with age of the SARS-CoV-2 infected patients. Methods. We performed a systematic review with meta-analysis (PROSPERO registration: CRD42020182677) where the databases (PubMed, SCOPUS, EMBASE, WHO, Semantic Scholar, and COVID-19 Primer) were searched for clinical studies published from January to April, 2020. Initially, the pooled prevalence of symptoms and comorbidity of COVID-19 patients were estimated using random effect model and the age ¿related factors were identified performing multivariate analysis [factor analysis]. Results. Twenty-nine articles with 4,884 COVID-19 patients were included in this study. Altogether, we found 33 symptoms and 44 comorbidities where the most frequent 19 symptoms and 11 comorbidities were included in the meta-analysis. The fever (84%), cough/dry cough (61%), and fatigue/weakness (42%) were found more prevalent while acute respiratory distress syndrome, hypertension and diabetes were the most prevalent comorbid condition. The factor analysis showed positive association between a cluster of symptoms and comorbidities with patients¿ age. The symptoms comprising fever, dyspnea/shortness of breath, nausea, vomiting, abdominal pain, dizziness, anorexia and pharyngalgia; and the comorbidities including diabetes, hypertension, coronary heart disease, COPD/lung disease and ARDS were the factors positively associated with COVID-19 patient¿s age. Conclusion. As an unique effort, this study found a group of symptoms (fever, dyspnea/shortness of breath, nausea, vomiting, abdominal pain, dizziness, anorexia and pharyngalgia) and comorbidities (diabetes, hypertension, coronary heart disease, COPD/lung disease and ARDS), associated with the age of COVID-19 infected patients.

Background: Data sparsity is a major limitation to estimating national and global dementia burden. Surveys with full diagnostic evaluations of dementia prevalence are prohibitively resource-intensive in many settings. However, validation samples from nationally representative surveys allow for the development of algorithms for the prediction of dementia prevalence nationally. Methods: Using cognitive testing data and data on functional limitations from Wave A (2001¿2003) of the ADAMS study (n = 744) and the 2000 wave of the HRS study (n = 6358) we estimated a two-dimensional item response theory model to calculate cognition and function scores for all individuals over 70. Based on diagnostic information from the formal clinical adjudication in ADAMS, we fit a logistic regression model for the classification of dementia status using cognition and function scores and applied this algorithm to the full HRS sample to calculate dementia prevalence by age and sex. Results: Our algorithm had a cross-validated predictive accuracy of 88% (86¿90), and an area under the curve of 0.97 (0.97¿0.98) in ADAMS. Prevalence was higher in females than males and increased over age, with a prevalence of 4% (3¿4) in individuals 70¿79, 11% (9¿12) in individuals 80¿89¿years old, and 28% (22¿35) in those 90 and older. Conclusions: Our model had similar or better accuracy as compared to previously reviewed algorithms for the prediction of dementia prevalence in HRS, while utilizing more flexible methods. These methods could be more easily generalized and utilized to estimate dementia prevalence in other national surveys.

Integration of religion in community health and wellbeing interventions is important for achieving a good life among faith-based populations. In countries hosting Muslim-minorities, however, relatively little is reported in academic literature on processes of faith integration in the development and delivery of interventions. We undertook a review of peer reviewed literature on health and wellbeing interventions with Muslim-minorities, with specific interest on how Islamic principles were incorporated. Major databases were systematically searched and PRISMA guidelines applied in the selection of eligible studies. Twenty-one journal articles met the inclusion criteria. These were coded and analyzed thematically. Study characteristics and themes of religiosity are reported in this review, including the religious tailoring of interventions, content co-creation and delivery design based on the teachings from the Quran and Sunnah, and applicability of intervention structures. We reviewed the philosophical and structural elements echoing the Quran and Islamic principles in the intervention content reported. However, most studies identified that the needs of Muslim communities were often overlooked or compromised. This may be due to levels of religiocultural knowledge of persons facilitating community health and wellbeing interventions. Our review emphasizes the importance of intellectual apparatus when working in diverse communities, effective communication-strategies, and community consultations when designing interventions with Muslim-minority communities.

Background: High rates of psychotropic medications are prescribed in aged care homes despite their limited effectiveness and associated adverse effects. We aim to evaluate the changes in prescription patterns for elderly residents with dementia in the ¿Harmony in the Bush Dementia Study¿. Harmony in the Bush is a person-centered model of dementia care in nursing homes, based on the principles of Progressively Lowered Stress Threshold and person-centered music intervention. Methods: Our larger study (12 weeks period) was a quasi-experimental design conducted in five rural nursing homes in Australia. Medication charts (n = 31) were collected retrospectively from three rural aged care facilities. Medication data for each resident was collected from a three-month medication charts, pre-intervention, and post-intervention. Fifty-three staff participated in 31 semi-structured interviews and 8 focus groups at post-intervention, and at 1-month and 3-months follow up. Results: The median age of the participants was 83 years, and 68% of them were female. Polypharmacy was measured in 87% (n = 27) of the participants. Hypertension, hyperlipidemia, diabetes, and the Alzheimer¿s disease were the major comorbidities identified in residents. None of the residents received more than the maximum dose of psychotropic medications recommended by the guidelines. There was a reduction of 22.4% (77.4% vs 55%) in the use of at least any psychotropic medications, 19.6% (39% vs, 19.4%) reduction in antipsychotics and benzodiazepines (39% vs 19.4%), and 6.5% (42% vs 35.5%) reduction in antidepressants prescription medicines, when comparing residents¿ medication charts data covering 3-months pre- and post-intervention, however, these changes were not statistically significant. Additionally, there was a decreasing trend in the use of inappropriate medications. Psychotropic medications were prescribed in up to 43% and anti-dementia medications in 44% of participants for more than 6 months. Three themes extracted from qualitative data include decrease behavioral and psychiatric symptoms of dementia due to medication weaning or dose tapering, other strategies to reduce medication use, and environmental or noise control. Conclusions: Our findings indicate that the Harmony in the Bush model as a non-pharmacological approach reduces the prescription of psychotropic medications in rural nursing homes as supported by findings from both quantitative and qualitative data.

Aim: Nursing is a social and collaborative profession; therefore, nursing education requires a pedagogy that supports the establishment of a collaborative learning community. Despite the limited use of the Community of Inquiry framework in Australian nursing courses, the educators viewed it as applicable for course design. This paper aims to understand Australian nurse educators' current practices in designing and delivering courses using the Community of Inquiry lens. Design and methods: This paper represent the second phase of the explanatory mixed-methods approach¿the data collected in October 2019 via semi-structured interviews with eleven nurse academics from 3 Australian universities. Results: the deductive thematic analysis using the Community of Inquiry coding template confirmed that the 'cognitive presence' and its indicators are implicitly embedded in online/blended courses. But the 'social presence' and 'teaching presence' are faced with some challenges: the underuse of discussion forums by students, the use of social media pages with exclusion of educators and the educators' role of content development rather than course design. Conclusions: The study findings suggest that the Community of Inquiry framework's explicit application would strengthen 'social and teaching' presences in nursing courses design. Further studies on nursing students' evaluation and perspectives about courses design regarding Community of Inquiry are essential.

Objective: Inter-professional education is a growing area of importance that enables training of health care professionals and students to develop skills in collaborative clinical practice, a critical aspect of disability care. However, research is limited on appropriate on-site inter-professional training for the rural and remote disability workforce. This paper aims to explore the features of an effective inter-professional training approach for rural disability workforce. Setting: Riverland, South Australia. Participants: Clinical educators, allied health professionals, health and service providers and students. Design: A qualitative-explorative research design, involving focus group discussion and a thematic analysis method were employed in this study. Participants of the focus group discussion completed a capacity building training program centred on inter-professional education, cultural-safety and the National Disability Insurance Scheme. National Disability Services Social Impact Measurement Tool was used to evaluate and explore the features of effective inter-professional training program for existing and emerging disability workforce in rural regions. Results: Four themes emerged from data analysis: inter-professional education focus; structured inter-professional training; building collaborative learning environment; and culturally appropriate care practice. Inter-professional supervision was identified as a key enabler for capacity building in an area with limited health workforce. Inter-agency collaboration and professional network were identified as important elements to support disability health workforce retention and the transition from novice to practitioner. Prior knowledge about the needs of persons with disability and empathetic relationships influenced the quality of practice. Conclusion: In situ training programs, which provide real-life rural practice context and harness inter-agency collaboration, improve effectiveness of rural disability workforce readiness for practice.

Senior women¿s access to medical care in rural Bangladesh is a major public health concern. This study aims to explore the system determinants that impact on rural senior women¿s utilization of healthcare. Following a qualitative critical social research design, healthcare staff and senior women living in three rural villages of Bangladesh were approached to participate in face-to-face audio-recorded interviews. A total of 11 staff and 25 senior women were interviewed with questions about health policy, healthcare services and management of aged care. Data was analyzed using a blend of critical discourse and thematic analysis methods. Several healthcare system determinants were identified that were complex and cross-sectional. Three major themes emerged from the system determinants: legal framework of aged care; inadequate healthcare support; and professional knowledge and skills of healthcare staff that led the rural senior women to avoid or delay access to hospitals and clinics. The findings revealed that a lack of health focus and professional skills among healthcare staff can be considered as critical. This study recommends that policy and organizational changes are made to improve the women¿s access to rural hospitals and clinics in Bangladesh.

Objectives: This paper aims to understand the factors influencing the adoption of teaching, social and cognitive presence in online nursing education and explain the novice nurse academics journey in adopting these aspects. Background: The quality of the online/blended courses is about the content and a need for suitable pedagogical design, clear instructions and a collaborative environment based on a valid and reliable theoretical framework. Design and settings: A qualitative study involves semi-structured interviews with 11 nurse academics from three Australian Universities and thematic analysis was conducted. Results and conclusions: The Community of Inquiry framework informed three themes including several factors in each from the interviews: (1) Teaching Presence (TP): the lack of understanding of educational theory use, the inadequate course evaluation and the resources scarcity found to be the factors affecting the adoption of TP in online nursing education; (2) Social Presence: the engagement difficulty and creating a learning community affected the adoption of SP; and (3) Cognitive Presence: the variety in learning styles and formative assessment and discussion forums found to be affecting the adoption of CP. This study paper is unique because it uses the Community of Inquiry framework and Meleis's Transition Theory and provides insight on how to facilitate the transition [from role insufficiencies to role supplementation to role mastery] of nurse academics¿ journey in adopting teaching, social and cognitive presence for online higher education.

There is great potential for human-centred technologies to enhance wellbeing for people living with dementia and their carers. The Virtual Dementia Friendly Rural Communities (Verily Connect) project aimed to increase access to information, support, and connection for carers of rural people living with dementia, via a co-designed, integrated website/mobile application (app) and Zoom videoconferencing. Volunteers were recruited and trained to assist the carers to use the Verily Connect app and videoconferencing. The overall research design was a stepped wedge open cohort randomized cluster trial involving 12 rural communities, spanning three states of Australia, with three types of participants: carers of people living with dementia, volunteers, and health/aged services staff. Data collected from volunteers (n = 39) included eight interviews and five focus groups with volunteers, and 75 process memos written by research team members. The data were analyzed using a descriptive evaluation framework and building themes through open coding, inductive rea-soning, and code categorization. The volunteers reported that the Verily Connect app was easy to use and they felt they derived benefit from volunteering. The volunteers had less volunteering work than they desired due to low numbers of carer participants; they reported that older rural carers were partly reluctant to join the trial because they eschewed using online technologies, which was the reason for involving volunteers from each local community.
