Development of a smartphone screening test for preclinical Alzheimer's disease and validation across the dementia continuum.

BACKGROUND: Dementia prevalence is predicted to triple to 152 million globally by 2050. Alzheimer's disease (AD) constitutes 70% of cases. There is an urgent need to identify individuals with preclinical AD, a 10-20-year period of progressive brain pathology without noticeable cognitive symptoms, for targeted risk reduction. Current tests of AD pathology are either too invasive, specialised or expensive for population-level assessments. Cognitive tests are normal in preclinical AD. Emerging evidence demonstrates that movement analysis is sensitive to AD across the disease continuum, including preclinical AD. Our new smartphone test, TapTalk, combines analysis of hand and speech-like movements to detect AD risk. This study aims to [1] determine which combinations of hand-speech movement data most accurately predict preclinical AD [2], determine usability, reliability, and validity of TapTalk in cognitively asymptomatic older adults and [3], prospectively validate TapTalk in older adults who have cognitive symptoms against cognitive tests and clinical diagnoses of Mild Cognitive Impairment and AD dementia. METHODS: Aim 1 will be addressed in a cross-sectional study of at least 500 cognitively asymptomatic older adults who will complete computerised tests comprising measures of hand motor control (finger tapping) and oro-motor control (syllabic diadochokinesis). So far, 1382 adults, mean (SD) age 66.20 (7.65) years, range 50-92 (72.07% female) have been recruited. Motor measures will be compared to a blood-based AD biomarker, phosphorylated tau 181 to develop an algorithm that classifies preclinical AD risk. Aim 2 comprises three sub-studies in cognitively asymptomatic adults: (i) a cross-sectional study of 30-40 adults to determine the validity of data collection from different types of smartphones, (ii) a prospective cohort study of 50-100 adults ≥ 50 years old to determine usability and test-retest reliability, and (iii) a prospective cohort study of ~1,000 adults ≥ 50 years old to validate against cognitive measures. Aim 3 will be addressed in a cross-sectional study of ~200 participants with cognitive symptoms to validate TapTalk against Montreal Cognitive Assessment and interdisciplinary consensus diagnosis. DISCUSSION: This study will establish the precision of TapTalk to identify preclinical AD and estimate risk of cognitive decline. If accurate, this innovative smartphone app will enable low-cost, accessible screening of individuals for AD risk. This will have wide applications in public health initiatives and clinical trials.

Australian nursing students' perception, knowledge, and attitude towards oral healthcare of older people and associated factors: a national cross-sectional survey.

BACKGROUND: The oral health of many older Australians is poor and associated with many systemic health problems. However, nurses often have a limited understanding of the importance of oral healthcare for older people. This study aimed to investigate Australian nursing students' perception, knowledge, and attitude toward providing oral healthcare for older people and associated factors. METHODS: A cross-sectional study was conducted among final year nursing students studying at accredited nursing programs using an online self-reported 49-item survey. The data were analysed using univariate and bivariate analysis (t-test, ANOVA, Spearman's correlation test). RESULTS: A total of 416 final-year nursing students from 16 accredited programs in Australia completed the survey. Mean scores showed that more than half of the participants felt they lacked confidence (55%, n = 229) and had limited knowledge about oral healthcare for older people (73%, n = 304); however, their attitude towards providing such care was favourable (89%, n = 369). A positive correlation was found between students' confidence in delivering oral healthcare to older people and their perceived knowledge (r = 0.13, p < 0.01). Results revealed a statistically significant positive association between students' experience in providing oral healthcare to older people and students' perception (t = 4.52, p < 0.001), knowledge (t = 2.87, p < 0.01), and attitude (t = 2.65, p < 0.01) mean scores in such care. Nearly 60% (n = 242) of participants received education/training in oral healthcare for older people at university, but this was often for less than one hour. Around 56% (n = 233) believed that the current nursing curriculum did not prepare them to provide effective oral healthcare to older people. CONCLUSION: Findings suggested a need for nursing curricula to be revised to include oral health education and clinical experience. Knowledge of evidence-based oral healthcare by nursing students may improve the quality of oral healthcare for older people.

A profile of students in a university-based distance dementia education program: Implications for policy and practice.

OBJECTIVE: The online program began in 2012 to support aged care workers without a tertiary education or vocational qualification. This paper documents changes in the student profile since initiation of the program, and how the program may support recommendations of the Royal Commission into Aged Care Quality and Safety and engage other educators, providers and policymakers. METHODS: Four hundred and seventy-one commencing undergraduate students completed a 16-item online survey in 2017 to document demographics and reasons for study. Categorical associations were assessed with univariate logistic regression in R v3.6. RESULTS: Most students (71%; 336) were aged between 41 and 60 years but the program now included younger (<41 years) and older (>80 years) people. Unlike the 2012 students, about 41% had tertiary-level qualifications, and 56% were employed in professional positions, including registered nurse, general practitioner and allied health professional. Professional and practice development was the primary reason for study; significantly so for younger (<41 years) participants in aged and dementia care (χ2 (5) = 18.15, p = 0.003) and for those with previous university experience (χ2 (4) = 22.17, p = 0.001). Older (≥61 years) participants enrolled to gain greater knowledge about dementia (χ2 (4) = 17.60, p = 0.002). CONCLUSIONS: Understanding the changed student profile guided program refinement to ensure the provision of effective, evidence-based education in dementia understanding and care. Work now focusses on increasing partnerships with aged care organisations, community and postsecondary training institutions to support a continuum of workforce development options, guided by the recommendations of the Royal Commission.

The TAS Test project: a prospective longitudinal validation of new online motor-cognitive tests to detect preclinical Alzheimer's disease and estimate 5-year risks of cognitive decline and dementia.

BACKGROUND: The worldwide prevalence of dementia is rapidly rising. Alzheimer's disease (AD), accounts for 70% of cases and has a 10-20-year preclinical period, when brain pathology covertly progresses before cognitive symptoms appear. The 2020 Lancet Commission estimates that 40% of dementia cases could be prevented by modifying lifestyle/medical risk factors. To optimise dementia prevention effectiveness, there is urgent need to identify individuals with preclinical AD for targeted risk reduction. Current preclinical AD tests are too invasive, specialist or costly for population-level assessments. We have developed a new online test, TAS Test, that assesses a range of motor-cognitive functions and has capacity to be delivered at significant scale. TAS Test combines two innovations: using hand movement analysis to detect preclinical AD, and computer-human interface technologies to enable robust 'self-testing' data collection. The aims are to validate TAS Test to [1] identify preclinical AD, and [2] predict risk of cognitive decline and AD dementia. METHODS: Aim 1 will be addressed through a cross-sectional study of 500 cognitively healthy older adults, who will complete TAS Test items comprising measures of motor control, processing speed, attention, visuospatial ability, memory and language. TAS Test measures will be compared to a blood-based AD biomarker, phosphorylated tau 181 (p-tau181). Aim 2 will be addressed through a 5-year prospective cohort study of 10,000 older adults. Participants will complete TAS Test annually and subtests of the Cambridge Neuropsychological Test Battery (CANTAB) biennially. 300 participants will undergo in-person clinical assessments. We will use machine learning of motor-cognitive performance on TAS Test to develop an algorithm that classifies preclinical AD risk (p-tau181-defined) and determine the precision to prospectively estimate 5-year risks of cognitive decline and AD. DISCUSSION: This study will establish the precision of TAS Test to identify preclinical AD and estimate risk of cognitive decline and AD. If accurate, TAS Test will provide a low-cost, accessible enrichment strategy to pre-screen individuals for their likelihood of AD pathology prior to more expensive tests such as blood or imaging biomarkers. This would have wide applications in public health initiatives and clinical trials. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT05194787 , 18 January 2022. Retrospectively registered.

Aboriginal Women Learning on Country: Lessons for Educators.

Introduction: This paper details the journey of eight Aboriginal women from Circular Head, a rural and remote area of North-West Tasmania, as they undertook an innovative 2-year program of tertiary studies in dementia to address a documented community need. The Chief Executive Officer of the Circular Head Aboriginal Corporation (CHAC) had identified difficulties being experienced by older members of the community. These difficulties included changes in behavior, memory, and communication, with profound consequences on social engagement and care needs from both individual and community perspectives. The community wished to know if a combined vocational and university program, completed on Country and in community, could serve as a culturally safe education pathway to empower Aboriginal members of a rural and remote area in providing community health and dementia education and care. Methods: The nationally funded program included a year-long face-to-face vocational Certificate III in Individual Support (Aging, Home, and Community) on Country, including within-community experience with adults with dementia. This face-to-face learning was combined with online study in the award-winning Bachelor of Dementia care offered by the University of Tasmania. Students received a PhD level stipend to support them in their studies and were guided by an Elder from their community. Results: All students completed their Certificate III. The number of units they completed toward the eight required for their Diploma of Dementia Care varied. Emergent themes from students' reflections were holistic and relational, highlighting achievements and challenges, the importance of on Country individual connections and community support, and the value of their current and future contributions to the community. Data from this mixed methods approach documented the impact of the innovative coupling of authentic, culturally appropriate experiential learning with broad and deep academic knowledge about dementia and evidence-based care. Conclusions: This program provided students with a work-related qualification embedded within a university education and increased the capacity and capability of this Aboriginal community to provide care for its members with dementia, a documented concern. The combination of vocational learning on Country with online university study established a pathway to improve students' access to and success in higher education and the professional workforce. This assisted in counteracting the negative influences of racism, stigma, rurality, and socio-economic marginalization on educational opportunity for Aboriginal people. Data showed the need for flexibility with this learning journey, and the strengths and resilience of these women as they learned.

Interdisciplinary Perspectives on Restraint Use in Aged Care.

Restraint use in Australian residential aged care has been highlighted by the media, and investigated by researchers, government and advocacy bodies. In 2018, the Royal Commission into Aged Care selected 'Restraint' as a key focus of inquiry. Subsequently, Federal legislation was passed to ensure restraint is only used in residential aged care services as the 'last resort'. To inform and develop Government educational resources, we conducted qualitative research to gain greater understanding of the experiences and attitudes of aged care stakeholders around restraint practice. Semi-structured interviews were held with 28 participants, comprising nurses, care staff, physicians, physiotherapists, pharmacists and relatives. Two focus groups were also conducted to ascertain the views of residential and community aged care senior management staff. Data were thematically analyzed using a pragmatic approach of inductive and deductive coding and theme development. Five themes were identified during the study: 1. Understanding of restraint; 2. Support for legislation; 3. Restraint-free environments are not possible; 4. Low-level restraint; 5. Restraint in the community is uncharted. Although most staff, health practitioners and relatives have a basic understanding of restraint, more education is needed at a conceptual level to enable them to identify and avoid restraint practice, particularly 'low-level' forms and chemical restraint. There was strong support for the new restraint regulations, but most interviewees admitted they were unsure what the legislation entailed. With regards to resources, stakeholders wanted recognition that there were times when restraint was necessary and advice on what to do in these situations, as opposed to unrealistic aspirations for restraint-free care. Stakeholders reported greater oversight of restraint in residential aged care but specified that community restraint use was largely unknown. Research is needed to investigate the extent and types of restraint practice in community aged care.

Poor oral hygiene, oral microorganisms and aspiration pneumonia risk in older people in residential aged care: a systematic review.

BACKGROUND: aspiration pneumonia increases hospitalisation and mortality of older people in residential aged care. OBJECTIVES: determine potentially pathogenic microorganisms in oral specimens of older people with aspiration pneumonia and the effect of professional oral care in reducing aspiration pneumonia risk. DATA SOURCES: PUBMED/MEDLINE, CINAHL, EMBASE, COCHRANE, PROQUEST, Google Scholar, Web of Science. STUDY ELIGIBILITY CRITERIA: published between January 2001 and December 2019 addressing oral microorganisms, aspiration pneumonia, oral health and treatment. PARTICIPANTS: people 60 years and older in residential aged care. STUDY APPRAISAL AND SYNTHESIS METHODS: the Newcastle-Ottawa Scale and the Standard Protocol Items: Recommendations for Intervention Trials checklist. RESULTS: twelve studies (four cross-sectional, five cohort and three intervention) reported colonisation of the oral cavity of older people by microorganisms commonly associated with respiratory infections. Aspiration pneumonia occurred less in people who received professional oral care compared with no such care. Isolation of Candida albicans, Staphylococcus aureus, methicillin-resistant S. aureus and Pseudomonas aeruginosa was related to mortality due to aspiration pneumonia. An interesting finding was isolation of Escherichia coli, a gut bacterium. LIMITATIONS: more information may be present in publications about other co-morbidities that did not meet inclusion criteria. A high degree of heterogeneity prevented a meta-analysis. Issues included sampling size, no power and effect size calculations; different oral health assessments; how oral specimens were analysed and how aspiration pneumonia was diagnosed. CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS: pathogenic microorganisms colonising the oral microbiome are associated with aspiration pneumonia in older people in residential care; professional oral hygiene care is useful in reducing aspiration pneumonia risk.

Incorporating oral health care education in undergraduate nursing curricula - a systematic review.

BACKGROUND: The recognised relationship between oral health and general health, the rapidly increasing older population worldwide, and changes in the type of oral health care older people require have raised concerns for policymakers and health professionals. Nurses play a leading role in holistic and interprofessional care that supports health and ageing. It is essential to understand their preparation for providing oral health care.Objective: To synthesise the evidence on nursing students' attitudes towards, and knowledge of, oral healthcare, with a view to determining whether oral health education should be incorporated in nursing education. METHODS: Data sources: Three electronic databases - PubMed, Scopus, and CINAHL.Study eligibility criteria, participants and interventions: Original studies addressing the research objective, written in English, published between 2008 and 2019, including students and educators in undergraduate nursing programs as participants, and conducted in Organisation of Economic Co-operation and Development countries.Study appraisal and synthesis methods: Data extracted from identified studies were thematically analysed, and quality assessment was done using the Mixed Methods Appraisal Tool. RESULTS: From a pool of 567 articles, 11 met the eligibility criteria. Findings documented five important themes: 1.) nursing students' limited oral health knowledge; 2.) their varying attitudes towards providing oral health care; 3.) the need for further oral health education in nursing curricula; 4.) available learning resources to promote oral health; and 5.) the value of an interprofessional education approach to promote oral health care in nursing programs.Limitations: The identified studies recruited small samples, used self-report questionnaires and were conducted primarily in the United States. CONCLUSIONS: The adoption of an interprofessional education approach with a focus on providing effective oral health care, particularly for older people, needs to be integrated into regular nursing education, and practice. This may increase the interest and skills of nursing students in providing oral health care. However, more rigorous studies are required to confirm this. Nursing graduates skilled in providing oral health care and interprofessional practice have the potential to improve the oral and general health of older people.

Geographical variation in preventable hospital admissions for dental conditions: An Australia-wide analysis.

OBJECTIVE: To describe the characteristics of hospital admissions for dental conditions, by Australian Statistical Geography Standard remoteness area for the 5 years 2010/2011 to 2014/2015. DESIGN: Retrospective analysis of preventable hospital admissions due to dental conditions. SETTING: National data set provided by the Australian Institute of Health and Welfare. PARTICIPANTS: Every hospital admission for patients who were admitted for dental conditions over five financial years, from 2010/2011 to 2014/2015. MAIN OUTCOME MEASURES: The number (and rate per 1000 population) of hospital admissions due to dental conditions in each Australian Statistical Geography Standard remoteness area (major city, inner regional, outer regional, remote and very remote). RESULTS: There were 316 937 hospital admissions for dental conditions over the 5-year period. The rate of potentially preventable dental hospital admissions ranged from an average of 2.5 per 1000 population in major cities to 3.2 in inner regional areas, 3.1 in outer regional areas, and 4.1 per 1000 in remote and very remote areas. The rate of admissions was highest among those aged 0-14 years living in remote (9.0-10.0 per 1000) and very remote (9.8-12.5 per 1000) areas. Dental caries was the most common reason for admissions. CONCLUSIONS: There is an urgent need to address the social determinants of oral health in children aged 0-14 years living in remote and very remote Australia. The delivery of mobile primary dental care services needs to be expanded in remote and very remote areas to prevent and treat dental caries.

Best intentions or best practice? A case study of the nutritional needs and outcomes of a person with dementia living in a residential aged care home.

AIMS: To evaluate the nutritional status and needs of a person with dementia living in an aged care home, including identification of barriers to, and effective strategies for, the provision of person-centred care. BACKGROUND: Nutrition and hydration care are integral to quality of life for adults with dementia, but there is little research on whether staff knowledge around effective care strategies for residents is translated into optimal care. DESIGN: Focused ethnographic single-case design. METHODS: The perspectives of the resident, her prime family member, and six care staff were triangulated through interviews, observation, document audit, and medical file review to investigate the resident's nutrition and hydration status and needs (October 2014-April 2015). RESULTS: During 3 years in care, this resident had lost weight steadily. Staff appeared attentive but did not maintain a systematic record of body mass index. At meals, staff encouraged eating but used ineffective strategies. Food was not served in ways that facilitated active participation. Eating and drinking were structured as tasks to be completed rather than activities to be enjoyed. CONCLUSION: This instrumental case study identified a task-oriented, rather than person-centred, approach to nutrition and hydration care, adversely affecting the resident's nutritional health and capability to participate actively.

Staff awareness of food and fluid care needs for older people with dementia in residential care: A qualitative study.

AIMS AND OBJECTIVES: To examine awareness of aged care home staff regarding daily food and fluid care needs of older people with dementia. BACKGROUND: Older people in residential care frequently are malnourished, and many have dementia. Staff knowledge of the food and fluid needs of people with dementia is limited. Qualitative research on this topic is scarce but can provide insight into how nutrition and hydration care may be improved. DESIGN: Qualitative, interview-based study. METHODS: Eleven staff in a range of positions at one care home were interviewed regarding their perceptions of current and potential food/fluid care practices. Transcripts were coded and analysed thematically. RESULTS: Key food and fluid issues reported by these staff members were weight loss and malnutrition, chewing and swallowing difficulties (dysphagia), and inadequate hydration. Staff identified a number of current care practices that they felt to be effective in facilitating older people's food and fluid intake, including responsiveness to their needs. Staff suggestions to facilitate food and fluid intake centred on improved composition and timing of meals, enhanced physical and social eating environment, and increased hydration opportunities. Staff commented on factors that may prevent changes to care practices, particularly the part-time workforce, and proposed changes to overcome such barriers. CONCLUSIONS: Staff were aware of key food and fluid issues experienced by the older people in their care and of a range of beneficial care practices, but lacked knowledge of many promising care practices and/or how to implement such practices. RELEVANCE TO CLINICAL PRACTICE: Staff need to be supported to build on their existing knowledge around effective food and fluid care practices. The numerous ideas staff expressed for changing care practices can be leveraged by facilitating staff networking to work and learn together to implement evidence-based change.

Advances in medical education and practice: role of massive open online courses.

Massive open online courses (MOOCs) are increasingly available in the area of health and medicine. These MOOCs are offered through various commercial and noncommercial online platforms. When offered through reputable institutions, they can provide valuable access to reliable information without the constraints of time, geographical location, or level of education. Most current courses appear introductory in nature. In its drive for quality health care, the National Academy of Medicine has prioritized a focus on known chronic care conditions. Many of these conditions are shared internationally. Among its initiatives, the academy encourages consumer and professional groups, patients, clinicians, health care organizations, and universities to work together to identify evidence-based care processes consistent with best practices, organize major prevention programs to target key associated health risk behaviors, and develop systems to measure and evaluate improvements in the provision of patient- and family-centered health care. Carefully designed and collaboratively developed MOOCs would appear a valuable resource to contribute to these initiatives. Such MOOCs can, 1) increase the health literacy of the public with regard to the prevention and treatment of known chronic care conditions, 2) provide ready access to continuing professional, and interprofessional, education, and 3) explore innovative teaching models for student learning focused on patient- and family-centered care. MOOCs would also appear helpful to facilitate effective communication among international communities of patients and clinicians, including student clinicians, with shared interests. Further, the accumulation of MOOC data through large-scale measurement and analysis, obtained nationally and internationally, has the potential to assist in greater understanding of the risk for diseases and their prevention, with this translating into medical education, and authentic, patient- and family-centered methods for student learning. This paper explores these issues.

A comparative analysis of policies addressing rural oral health in eight English-speaking OECD countries.

INTRODUCTON: Oral health is fundamental to overall health. Poor oral health is largely preventable but unacceptable inequalities exist, particularly for people in rural areas. The issues are complex. Rural populations are characterised by lower rates of health insurance, higher rates of poverty, less water fluoridation, fewer dentists and oral health specialists, and greater distances to access care. These factors inter-relate with educational, attitudinal, and system-level issues. An important area of enquiry is whether and how national oral health policies address causes and solutions for poor rural oral health. The purpose of this study was to examine a series of government policies on oral health to (i) determine the extent to which such policies addressed rural oral health issues, and (ii) identify enabling assumptions in policy language about problems and solutions regarding rural communities. METHODS: Eight current oral health policies were identified from Australia, New Zealand, Canada, the USA, England, Scotland, Northern Ireland, and Wales. Validated content and critical discourse analyses were used to document and explore the concepts in these policy documents, with a particular focus on the frequency with which rural oral health was mentioned, and the enabling assumptions in policy language about rural communities. RESULTS: Seventy-three concepts relating to oral health were identified from the textual analysis of the eight policy documents. The rural concept addressing oral health issues occurred in only 2% of all policies and was notably absent from the oral health policies of countries with substantial rural populations. It occurred most frequently in the policy documents from Australia and Scotland, less so in the policy documents from Canada, Wales, and New Zealand, and not at all in the oral health policies from the US, England, and Northern Ireland. Thus, the oral health needs of rural communities were generally not the focus of, nor included in, the oral health policy documents in this study. When the language of concepts related to rural oral health was examined, the qualitative analysis identified four discourse themes related to both causality and solutions. These ranked discourse themes focused on service models, workforce issues, social determinants of health, and prevention. None of the policies addressed the structural economic determinants of unequal rural oral health, nor did they specifically assert the rights of children in rural communities to equitable oral health care. CONCLUSIONS: This study documented the limited focus on rural oral health that existed in national oral health policies from eight different English-speaking countries. It supports the need for an increased focus on rural oral health issues in oral health policies, particularly as increased oral health is clearly associated with increased general health. It speaks to the critical importance of periodic analysis of the content of oral health policies to ensure that issues of inequality are addressed. Further, it reinforces the need for research findings about effective oral health care to be translated into practice in the development of practical and financially viable policies to make access to oral health care more equitable, particularly for people living in rural and remote areas.

Interprofessional curriculum development achieves results: Initial evidence from a dementia-care protocol.

This report describes the outcomes of a five-day, protocol-based interprofessional education (IPE) initiative to prepare undergraduate medical, nursing, and paramedic students for collaborative work with adults with dementia. Clinical placements provided a structured and supervised IPE experience for 127 students in two Residential Aged Care Facilities (RACFs) in Hobart, Australia, during 2013 and 2014. The IPE activity was based on a seven-step protocol formulated by an interprofessional team of educators and aged care practitioners that revolved around collaborative assessments of adults with complex health needs. This article describes the IPE protocol and presents the results of a pre- and post-placement attitude questionnaire and knowledge quiz administered to evaluate student attitudes towards IPE and knowledge of dementia. Data suggest that a five-day, supervised, and protocol-based IPE experience in a dementia-care setting can inculcate positive changes in student attitudes about collaborative practice and may encourage dementia-related learning outcomes.

Relationship between participants' level of education and engagement in their completion of the Understanding Dementia Massive Open Online Course.

BACKGROUND: The completion rates for Massive Open Online Courses (MOOCs) generally are low (5-10%) and have been reported to favour participants with higher (typically tertiary-level) education. Despite these factors, the flexible learning offered by a MOOC has the potential to provide an accessible educational environment for a broad spectrum of participants. In this regard, the Wicking Dementia Research and Education Centre has developed a MOOC on dementia that is evidence-based and intended to address this emerging major global public health issue by providing educational resources to a broad range of caregivers, people with dementia, and health care professionals. METHODS: The Understanding Dementia MOOC was designed specifically to appeal to, and support, adult learners with a limited educational background. The nine-week course was presented in three units. Participants passed a quiz at the end of each unit to continue through the course. A series of discussion boards facilitated peer-to-peer interactions. A separate "Ask an Expert" discussion board also was established for each unit where participants posted questions and faculty with expertise in the area responded. RESULTS: Almost 10,000 people from 65 countries registered; 4,409 registrants engaged in the discussion boards, and 3,624 (38%) completed the course. Participants' level of education ranged from postgraduate study to a primary (elementary) school education. Participants without a university education (vocational certificate and below) were as likely as those with a university education to complete the course (χ(2) = 2.35, df = 6, p = 0.88) and to engage in the online discussions (F[6, 3799] = 0.85, p = 0.54). Further, participants who completed the MOOC engaged in significantly more discussion board posts than participants who did not complete the course (t = 39.60, df = 4407, p <0.001). CONCLUSIONS: The high completion rate and level of engagement of participants across a broad spectrum of levels of education suggest that MOOCs can be successfully developed and delivered to students from diverse educational backgrounds. The high participation rate also highlights the combination of MOOC design as well as the scale of unmet need for quality dementia education.

Nursing identity and patient-centredness in scholarly health services research: a computational text analysis of PubMed abstracts 1986-2013.

BACKGROUND: The most important and contested element of nursing identity may be the patient-centredness of nursing, though this concept is not well-treated in the nursing identity literature. More conceptually-based mapping of nursing identity constructs are needed to help nurses shape their identity. The field of computational text analytics offers new opportunities to scrutinise how growing disciplines such as health services research construct nursing identity. This paper maps the conceptual content of scholarly health services research in PubMed as it relates to the patient-centeredness of nursing. METHODS: Computational text analytics software was used to analyse all health services abstracts in the database PubMed since 1986. Abstracts were treated as indicative of the content of health services research. The database PubMed was searched for all research papers using the term "service" or "services" in the abstract or keywords for the period 01/01/1986 to 30/06/2013. A total of 234,926 abstracts were obtained. Leximancer software was used in 1) mapping of 4,144,458 instances of 107 concepts; 2) analysis of 106 paired concept co-occurrences for the nursing concept; and 3) sentiment analysis of the nursing concept versus patient, family and community concepts, and clinical concepts. RESULTS: Nursing is constructed within quality assurance or service implementation or workforce development concepts. It is relatively disconnected from patient, family or community care concepts. CONCLUSIONS: For those who agree that patient-centredness should be a part of nursing identity in practice, this study suggests that there is a need for development of health services research into both the nature of the caring construct in nursing identity and its expression in practice. More fundamentally, the study raises questions about whether health services research cultures even value the politically popular idea of nurses as patient-centred caregivers and whether they should.

Student reflections following exposure to a case-based interprofessional learning experience: Preliminary findings.

This study analyzed students' written reflections following their initial exposure to interprofessional teamwork in case-based problem-solving. A three-hour seminar featuring three sequenced scenarios was developed and offered 12-times over two semesters. A total of 305 students from a variety of healthcare programs worked together with standardized patients in an on-campus laboratory simulating hospital ward and rehabilitation settings. A thematic analysis of students' reflections showed that they valued the shared learning and realistic case study. However, they felt the experience would be strengthened by working in smaller, more representative teams that included students from medicine, psychology, and social work to enable more effective communication and comprehensive case discussion. While useful for future planning, the identified themes did not enable a comparative statistical analysis of what students found helpful and difficult and a re-coding of students' responses now is underway. Implications for measuring the effectiveness of future interprofessional case-based learning center on addressing the identified weaknesses, and establishing a research design that enables a comparison of pre- and post-seminar data, and the effectiveness of the IPE experience compared to profession-specific experiences.

Hydration in older adults: the contribution of bioelectrical impedance analysis.

The sensory and gastrointestinal changes that occur with ageing affect older adults' food and liquid intake. Any decreased liquid intake increases the risk for dehydration. This increased dehydration risk is compounded in older adults with dysphagia. The availability of a non-invasive and easily administered way to document hydration levels in older adults is critical, particularly for adults in residential care. This pilot study investigated the contribution of bioelectrical impedance analysis to measure hydration in 19 older women in residential care: 13 who viewed themselves as healthy and six with dysphagia. Mann-Whitney U analyses documented no significant between-group differences for Total Body Water (TBW), Fat Free Mass (FFM), Fat Mass (FM), and percentage Body Fat (%BF). However, when compared to previously published data for age-matched women, the TBW and FFM values of the two participant groups were notably less, and FM and %BF values were notably greater than expected. If results are confirmed through continued investigation, such findings may suggest that long-term care facilities are unique environments in which all older residents can be considered at-risk for dehydration and support the use of BIA as a non-invasive tool to assess and monitor their hydration status.

Understanding the research-policy divide for oral health inequality.

BACKGROUND: No studies exist of the congruence of research in oral health to policy. This study aimed to examine the broad congruence of oral health research to policy, and implications for developing oral health research that is more policy relevant, particularly for the wider challenge of addressing unequal oral health outcomes, rather than specific policy translation issues. METHODS: Bayesian-based software was used in a multi-layered method to compare the conceptual content of 127,193 oral health research abstracts published between 2000-2012 with eight current oral health policy documents from Organisation for Economic Co-operation and Development countries. FINDINGS: Fifty-five concepts defined the research abstracts, of which only eight were policy-relevant, and six of which were minor research concepts. CONCLUSIONS: The degree of disconnection between clinical concepts and healthcare system and workforce development concepts was striking. This study shows that, far from being "lost in translation," oral health research and policy are so different as to raise doubts about the extent to which research is policy-relevant and policy is research-based. The notion of policy relevance encompasses the lack of willingness of policy makers to embrace research, and the need for researchers to develop research that is, and is seen to be, policy-relevant.
