Abstract: Social robots such as Paro, a therapeutic companion robot, have recently been introduced into dementia care as a means to reduce behavioural and psychological symptoms of dementia. The purpose of this study was to explore care staff perceptions of Paro and a look-alike non-robotic animal, including benefits and limitations in dementia care. The study assumed a descriptive qualitative approach, nested within a large cluster-randomised controlled trial. We interviewed a subs le of 20 facility care staff, from nine long-term care facilities in Southeast Queensland, Australia. Thematic analysis of the data, which was inductive and data-driven, was undertaken with the assistance of the qualitative software, ATLAS.ti®. The findings refer to four categories: increasing excitement for Paro and decreasing enthusiasm for Plush Toy value and function of Paro opportunities for engagement and alternatives vs. robustness. Staff caring for people with dementia preferred Paro compared to a look-alike Plush Toy. Staff identified that Paro had the potential to improve quality of life for people with dementia, whereas the Plush Toy had limitations when compared to Paro. However, participants expressed concern that the cost of Paro could reduce opportunities for use within aged care.

Abstract: As the cohort of students in Australian universities become increasingly erse, attention to ensuring their success is an emerging issue of social justice in tertiary education. Navigating transitions through the student journey is crucial to their success. Exploring and responding to the needs of a cohort of first-year students is the focus of this research. Using a participatory action approach, this project aimed to discover what is meaningful for first-year students, by exploring how students experienced the processes of admission, enrolment, commencement, and learning and teaching in two fast-track and one online health degrees. Nine students were partnered with nine academics for a six-month period. The analysis offers insights into equity issues in relation to the institution’s admission processes, the quality of support and engagement from academics to students when transitioning to university life, and how students find their ‘place’. Strategies to support the transition process for first-year students are identified and discussed.

Abstract: The 2019 Royal Commission into Aged Care Quality and Safety highlighted the need for First Nations peoples to have improved, culturally safe care. This paper is a call to action for First Nations peoples to be involved in developing culturally safe care and services to be embedded within Australian aged care services. The first screening examined the Australian literature (peer‐reviewed articles published since 2010 in English) detailing key aspects relevant to Cultural Safety for First Nations peoples supported by aged care services in Australia. The second screening assessed whether the findings of these studies aligned with the key aspects of Cultural Safety of First Nations peoples in aged care. The initial literature search yielded 198 papers, of which 13 met the inclusion criteria for the final review. Topics that required further interrogation included barriers to communication, racism and discrimination, impacts on health outcomes, health‐care workforce education needs and the importance of cultural connections to Country and kin. These topics influenced the perception of First Nations peoples feeling culturally safe when supported by aged care services. The literature identified a need to recruit more First Nations peoples into the aged care workforce, involve more First Nations family and community members in aged care and retain a consistent workforce overall. Together these strategies were seen to address the barriers that continue to affect aged care provision for First Nations peoples.

Abstract: This study sought to explore the effect of the family involvement in care (FIC) intervention on family and staff well-being over a nine-month period in a long-term care (LTC) facility providing dementia care. A quasi-experimental design with randomised allocation of two LTC sites but not the participants was employed. Family caregivers (n = 57) of residents with dementia and staff (n = 59) from two LTC facilities in Queensland, Australia, were recruited. Participants were assessed once pre-intervention and three times post-intervention for knowledge, stress and satisfaction outcomes. Between-group and within-group effects were analysed using ANOVAs at <0.05 level of significance. Pre- and post-intervention interviews from a purposive s le of family caregivers were also conducted to enhance understanding of FIC benefits. Beneficial intervention effects associated with family caregivers' knowledge of dementia were found (p < 0.001). Negative intervention effects were also found for family satisfaction outcomes in relation to staff consideration of their relatives and management effectiveness (p < 0.05). In addition, staff well-being and job satisfaction were found to be negatively affected by their perceived inappropriate behaviour of residents with dementia (p < 0.05). Participation in the FIC intervention improved family caregiver knowledge. The major barrier to the success of the partnership intervention in achieving beneficial long-term psychosocial effects for family and staff caregivers was lack of resources and leadership required to support collaboration between family and staff, mainly due to environment and structural changes. This study contributes to our understanding of the importance of partnerships in promoting family involvement in dementia care.

Abstract: To outline the experiences of family caregivers in Brisbane, Australia who have placed a relative with dementia into long-term care. Whilst the aged care literature in Australia highlights the rising numbers of people with dementia admitted to long-term care, empirical research exploring family and staff relationships and their influence on quality of care remains limited. International research demonstrates that the transition to long-term care is stressful for families and the person with dementia, often resulting in ongoing family and staff conflict. The study utilised a descriptive qualitative design. A purposive s le of 10 participants from a large study that tested an education intervention took part in the qualitative phase of this mixed method, sequential design study. Semi-structured interviews and confirmatory thematic analysis were used to identify family caregiver experiences following placement of their relative in long-term care. The findings emphasise the increasing isolation and burden of care felt by families prior to admission, which often is perpetuated during long-term care placement and may present as dissatisfaction with care. Improving staff-family relationships has the potential to reduce conflict and to improve the long-term care environment, relieve the pressure of work overload, decrease staff frustration and reduce negative reactions to family caregivers. The findings highlight the crucial need for long-term care facilities to support families, as well as the person with dementia, through the transition to the care environment. The resulting improved family relationships with staff, based on negotiation and increasing knowledge of dementia care, can then provide potential to develop more specialised evidence-based dementia care and service delivery.

Abstract: Recent years have seen social robotic pets introduced as a means of treating behavioral and psychological symptoms of dementia, and many show promising potential. In this study, we sought to explore family members' perceptions of the Japanese-developed baby harp seal, Paro (version 9), and a look-alike, nonrobotic Plush Toy, when used by their relative with dementia for 15 min, 3 afternoons per week for 10 weeks. The study employed a descriptive qualitative approach, which was nested within a larger cluster randomized controlled trial. A convenience s le of 20 family members (n = 10 each from the Paro and Plush Toy conditions) with relatives in 9 long-term care facilities in Queensland, Australia, completed in idual semi-structured interviews (telephone or face-to-face). Inductive, data-driven thematic analysis of the data was undertaken with the assistance of the qualitative management software, ATLAS.ti®. Family members of long-term care residents with dementia expressed positive perceptions of the Paro, perceiving that it improved mood, reduced agitation, and provided opportunity for communication for their relative. Negative perceptions of the Plush Toy were given by family members, primarily because of its lack of movement and engagement. Family members were keen for their older relative with dementia to use a social robot that moved and engaged with them, and Plush Toys that were static and unresponsive were perceived as being unimportant in improving quality of life. However, the current cost of Paro was identified by family members as a major limitation to use.

Abstract: Reablement is described as a goal directed intervention with a view to maintain or improve the independence of clients through "doing with, rather than doing for". As a relatively new concept in care, lack of specific skills in reablement is not uncommon, however, intrinsic values aligned with reablement are beneficial to organisations providing care and support to clients. The aim of this study is to develop a pre-employment questionnaire to assess readiness for a reablement approach to care as a step towards developing a reablement culture across organisations. A questionnaire based on activities of daily living (ADL), developed by the research team in consultation with a local community-based care organisation, was completed by 166 staff members at a community-based care organisation in Tasmania across several timepoints during and following reablement education sessions in 2018. The scores from these questionnaires were utilised to develop a questionnaire appropriate for determining readiness for reablement prior to employment within the organisation. Over a period of twelve months, a total of 407 Reablement Readiness Questionnaires were submitted by staff, indicating high levels of willingness to engage in reablement prior to and following the education sessions. Exploratory factor analyses were performed, and the construct validity and internal consistency of the emerging factors were assessed. An exploratory factor analysis indicated that ADL, in relation to reablement, consist of three dimensions-Lifestyle, My body and Connecting. The corresponding questions were subsequently built into an online questionnaire for pre-employment use. This questionnaire also has potential benefit in recruitment of staff to other community service organisations, to ascertain their readiness for reablement prior to beginning a variety of different roles within client care and support.

Abstract: Family caregiving for people with younger onset dementia affects everyone in the family unit. This article presents findings of a qualitative systematic review exploring the experiences of family caregivers of persons with younger onset dementia. A systematic search resulted in the inclusion of five relevant articles, and two groups within the family unit were identified—child caregivers and adult and spousal caregivers. Using the thematic synthesis approach, five themes emerged: dementia damage, grief for loss of relationship, changes in family roles, positive and negative impacts of family caregiving, and transition to formal care. The review findings support increasing evidence that despite the stress of caring for a person with dementia damage, family members have the capacity to cope, adapt, and grow through their experiences. Nurses can assist families to identify their unique strengths and enhance family resiliency so they can navigate the “lonely road” of younger onset dementia.

Abstract: This paper presents an evaluation of the pilot aged care clinical placement undertaken by undergraduate paramedic students in the university-based Wicking Dementia Research and Education Centre's Teaching Aged Care Facilities Program. The objective is to examine the learning experiences of students taking part in the first paramedic student clinical placement in Tasmania to be situated in the residential aged care environment. The students’ interactions with residents with dementia and with older people requiring a palliative approach to care are discussed, as key strategies to enhance paramedic student learning. Twenty-one final year undergraduate paramedic students completed a 5-day (40 hour) clinical placement in September/October 2011, in two participating residential aged care facilities in Tasmania, Australia. Qualitative data were obtained from weekly feedback meetings with students, which were audio-recorded, transcribed, and subjected to content analysis. Quantitative data from pre and post-placement questionnaires were collected and descriptive analyses performed. The data showed that students enjoyed interaction with residents and that this built their communication skills, particularly with residents with dementia. Students also learnt about the importance of a palliative approach to care and improved their knowledge of dementia. A supported placement program for paramedic students in residential aged care facilitates student learning in a number of areas, particularly around working with people with dementia, which is likely to enhance student readiness for the graduate paramedic role.

Abstract: The idea of radiographer image interpretation has not been fully explored in Fiji despite the great shortage of radiologists in the country. This is a feasibility study of radiographer image interpretation aimed at assessing the accuracy of radiographers in interpreting adult chest X-ray images at the Colonial War Memorial Hospital (CWMH) in Fiji. Forty PA chest X-ray images were interpreted in terms of correctly commenting on the presence/ absence of pathology, the name of the pathology, and the location of the pathology on the data sheets by the CWMH diagnostic radiographers (n = 14). The radiographers were grouped according to their years of work experience (≤ 5 vs > 5) and the Mann Whitney U test on a two-tailed p-value of 0.05 was used to compare this grouping. The data analysis was conducted using the Statistical Package for Social Sciences (SPSS) v.25 and Microsoft Excel. The diagnostic performance of all radiographers in terms of triaging normal and abnormal in the images shows sensitivity ranging from 71.4 to 100%, with specificity ranging from 47.4 to 100%. The mean sensitivity, specificity, and the overall accuracy of radiographers in triaging normal and abnormal on the images were 89.5%, 72.9%, and 81.6%, respectively. The mean accuracy in naming the pathology was 33.6% and the location sensitivity was 45.7%. There was no statistically significant difference in results between the radiographers' years of experience. Without any formal qualification, training, and practice, the current results suggest that the cohort of radiographers can perform normal/abnormal triage of CXRs within a test setting. With a significant reduction in the radiographers' accuracy in terms of naming and locating the abnormality, the study results do not support image interpretation by the radiographers at this stage. This feasibility study provides baseline information about the accuracy of image interpretation by diagnostic radiographers at CWMH and provides a platform for further research in image interpretation in Fiji.

Abstract: Background: SCARF (Status, Certainty, Autonomy, Relatedness and Fairness) is a neuroscience model based on reward and threat that has been used in a number of areas, such as coaching and group facilitation including practice development, performance management and leadership development. Aim: The aim of this article is to understand readiness for transformation in the workplace by considering the impact of a new philosophy of care called ‘reablement’ on behaviour change in health services staff, using a modified SCARF questionnaire. Methods: The quantitative survey was nested in a larger health services project to introduce the philosophy of reablement to 166 staff members of a regional community care organisation. The data collection instrument was modified to combine the five SCARF domains into statements related to reablement. Data were collected from participants at six timepoints before and after project staff training. Results: The results show that for each SCARF domain, staff responses remain relatively stable. Results indicate a consistently positive response to the philosophy of reablement, reflecting a high level of comfort and engagement with the change-management process. Conclusion: Evaluating reflection and change over time using SCARF can support training and other methods of change management in the context of a community care organisation. Further development is needed with different groups, and different change-management projects within health services. Implications for practice: The SCARF model can be applied to organisational change in health and community care with benefits for clients, staff, stakeholders and the organisation as a whole This model has previously been used to improve organisational communication and collaboration but this article suggests it also has a positive impact on overall change management, with a particular focus on understanding the factors related to behaviour in health and community care

Abstract: As the population ages, risk factors commonly shared by chronic degenerative disease can be exacerbated by behaviours and lifestyle choices. There is increasing evidence that those affected by chronic disease (and associated symptoms such as pain), depression and adverse behavioural and lifestyle patterns are at risk of substance misuse. This paper overviews substance use in Baby Boomers, which are defined as people aged between 52-70 years old, and the implications this may have on their mental health and well-being. We provide an overview of the characteristics of the Baby Boomer generation, their health status and what is currently known about their substance use and misuse. A strengthening of older adult mental health outpatient services is recommended to prevent and address substance use among older adults. Further research examining factors that influence substance use among this group could better inform health promotion programs targeting Baby Boomers.

Abstract: The aim of this scoping review is to explore the evidence by which community service providers have integrated reablement models of staff training and client assessment into practice. The concept of reablement, which has emerged during the last two decades globally, has recently been defined by health experts from 11 countries through a Delphi study. Reablement is seen as a way to support integrated frameworks that achieve person-centred, long-term care and assistance across community settings. International research indicates there is some evidence of developing models of reablement that include staff training and in idual components of client assessment. However, evidence of integrating reablement into interdisciplinary practice continues to be sparse. The review adopted the preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) approach. Inclusion criteria for the review related to community care, primary care, long-term care, and residential care. Populations of interest included service providers, interdisciplinary staff, trainers, and assessors. A total of 11 papers were reviewed. The studies varied in their approach to reablement training and client assessment frameworks. Three studies included assessment of staff well-being. All included evidence-based, person-centred components that can be integrated across health care settings. Single disciplinary approaches were used in all studies and some included training evaluation. This review has identified that currently reablement models are not yet embedded as frameworks for practice by community service providers in primary health care settings. Different programmes of training and assessment are being designed based on single disciplinary approaches and the context in which they are delivered. Further developmental work is required to integrate the components of discipline-specific training programmes within interdisciplinary frameworks. This will achieve not only an integrated framework for delivery across settings but also further the success of ‘ageing in place’ policy.

Abstract: This study aims to provide economic evidence of the cost‐effectiveness of employing specialist Parkinson's nurses in a regional community in Australia. This retrospective study utilized hospital service usage data to compare outcomes for people with Parkinson's disease before and after the employment of a specialist Parkinson's nurse in a regional community. A representative s le was drawn from the target population of people with a diagnosis of Parkinson's admitted to a regional hospital over a 4‐year period (2013–2014 and 2016–2017). A multiple regression approach and cost–benefit analysis were used to examine hospital costs related to length of stay based on hospital records. All costs were attributed to resource allocation according to service category and the national funding system. Quantitative data were analysed using Strata Analytics. Statistical findings demonstrated a reduction in hospital length of stay ranging from 0.37 (AUD$1924) to 0.755 day (AUD$3926) after the establishment of the specialist Parkinson's nurse. The cost–benefit analysis showed a net dollar benefit, or savings in hospital costs, of up to $8600.00 per person over a 3‐year period, as a result of the specialist Parkinson's nurse intervention. The statistical results show significant cost benefits associated with reduced length of hospital stay following introduction of the specialist Parkinson's nurse. These findings support advocacy for sustainable specialist Parkinson's nurse positions and have the potential to inform and influence policy and systemic changes within the health care system. The benefits of embedding specialist nursing services for people with Parkinson's disease in primary health settings include the direct impact on the potential to avoid hospital admissions due to worsening symptoms, improving quality of life for the person with Parkinson's and slowing the trajectory of the disease. Additional benefits are increased access to specialist services and reduced family caregiver burden.

Abstract: The study aimed to identify the potential for aged care placements to deliver benefits for second year nursing students when conducted within a supportive framework with debriefing and critical reflection opportunities. Given the ageing population and complex care needs of aged care facility residents, exacerbated by the high prevalence of dementia, the healthcare workforce's ability to meet older people's care needs is paramount. Yet research shows that nursing students are disengaged from aged care. Using a quasi-experimental mixed method design within an action research framework, 40 students were allocated a 3-week supported placement in 2011-2012 at one of the two intervention residential aged care facilities in Tasmania, Australia. Staff formed mentor action research groups in each facility and participated in a pre-placement capacity-building programme. Thirty-nine students were placed across 14 control facilities. Data were collected via meetings with students and pre-post placement questionnaires on placement experiences, attitudes and dementia knowledge. The intervention facility placement programme led to mentors and students being well prepared for the placement and to students experiencing enhanced teaching and learning derived from high levels of mentor support and increased autonomy. Students' knowledge, understanding and attitudes around aged care and dementia improved. Mentors working together within an action research framework can provide a supported residential aged care placement for nursing students that improves students' aged care attitudes and understandings. Provision of quality, supported aged care student placements is vital to prepare a new generation of nurses who will have to deal with the complex chronic healthcare needs associated with an ageing population.

Abstract: To explore staff knowledge of delirium by eliciting meaning through descriptions of their experiences within a residential aged care facility (RACF). Six staff from one RACF in Australia participated in this qualitative study. Semi-structured in idual interviews were conducted and analysed using Colaizzi's analytical framework. The analysis revealed four themes: (i) absence of the word delirium (ii) care based on intuition and automated actions (iii) reliance on teamwork and (iv) confusing delirium, depression and dementia. Delirium was absent from clinical discourse in the RACF. Although participants concluded that delirium was common, lack of knowledge led to under-assessment. Findings emphasise the need for staff education, informed assessment and clinical guidelines to better support staff care for residents.

Abstract: The residential aged care sector is reportedly a less attractive career choice for nursing students than other sectors. Research shows that students are often fearful of working with residents with dementia when they are inadequately supported on clinical placements by aged care staff. Thirty first-year nursing students attended a 2-week placement in one of two Tasmanian aged care facilities as part of the Wicking Dementia Research and Education Centre Teaching Aged Care Facilities Program, which aims to provide students with a quality aged care placement focusing on dementia palliation. Placement experience and dementia knowledge were evaluated through preplacement and postplacement questionnaires and weekly feedback meetings with mentors and students. Students had more positive attitudes related to aged care and higher dementia knowledge at the end of placement. Students described their interactions with residents with dementia and thought that the placement had increased their capacity to provide quality care to these residents. The findings indicate that residential aged care placements can be productive learning environments for novice nursing students. [ J Nurs Educ. 2014 (7):410–414.]

Abstract: This paper reports on the design of a program that aims to prototype teaching aged care facilities in Australia. Beginning in two Tasmanian residential aged care facilities, the intent of the program is to support large-scale inter-professional student clinical placements, positively influence students’ attitudes toward working in aged care and drive development of a high-performance culture capable of supporting evidence-based aged care practice. This is important in the context of aged care being perceived as an unattractive career choice for health professionals, reinforced by negative clinical placement experiences. The Teaching Aged Care Facilities Program features six stages configured around an action research/action learning method, with dementia being a key clinical focus.

Abstract: To explore the role and needs of the family carer across different acute care contexts and their level of involvement in the care of their relative with dementia in this setting. A pragmatic, exploratory-descriptive qualitative approach. A convenience s le of 30 family carers across three sites completed semi-structured interviews. Family carers wanted to be involved in the acute care of their family member with dementia. They acknowledged the importance of a central source of information, educated staff, guidelines on roles and processes, and positive communication, as well as respect from staff for the carer's knowledge of the older person and their needs. They also highlighted the need for medical staff to discuss with them the family member's treatment and care. There is a need for family-focused interventions to improve communication and involvement of family in the care of family members with dementia in the acute setting.

Abstract: This paper synthesises the results of three participatory action research (PAR) studies undertaken to improve the integration of evidence-based practice (EBP) education in three undergraduate health courses at one Australian university: Bachelor of Nursing, Bachelor of Occupational Therapy, and Bachelor of Physiotherapy. The PAR process with interested academics uncovered a range of EBP education strengths and weaknesses in the three courses. Common themes were evident, which are likely to be applicable in other similar courses. Identified weaknesses included a lack of explicit teaching about the meaning, principles, steps, and importance of EBP, partly stemming from a lack of shared understanding. A relative lack of emphasis on certain EBP steps was also noted, particularly the first step of ‘asking’ questions. A lack of communication with workplace learning (WPL) supervisors about how to facilitate EBP was also noted, raising concerns about variable EBP-education quality across WPL settings. Opportunities for improvement were identified by academics in each course, across multiple subjects and year levels. In our experience, PAR has been a highly constructive approach to EBP curriculum improvement. We encourage consideration of a PAR approach for addressing similarly complex curriculum challenges.

Abstract: This Participatory Action Research (PAR) project aimed to engage students from an accelerated 'fast track' nursing program in a mentoring collaboration, using an interdisciplinary partnership intervention with a group of academics. Student participants represented the disciplines of nursing and paramedicine with a high proportion of culturally and linguistically erse (CALD) students. Nine student mentors were recruited and paired with academics for a three-month ‘mentorship partnership’ intervention. Data from two pre-intervention workshops and a post-intervention workshop were coded in NVivo11 using thematic analysis. Drawing on social inclusion theory, a qualitative analysis explored an iteration of themes across each action cycle. Emergent themes were: 1) ‘building relationships for active engagement’, 2) ‘voicing cultural and social hierarchies’, and 3) ‘enacting collegiate community’. The study offers insights into issues for contemporary accelerated course delivery with a erse student population and highlights future strategies to foster effective student engagement.

Changes in nutrients and temperature will cause phytoplankton to be smaller but the consequences of these changes are uncertain because of a lack of knowledge regarding how changes in cell size affect function within a species. This project will evolve 20 species of algae to be different sizes and estimate the consequences of these size changes for biological functions. The project will then use these data to refine global models of carbon budgets, leading to better predictions about how the global carbon pump will change. Read more Read less
