RESUMEN

BACKGROUND: Wide interhospital variations exist in cardiovascular intensive care unit (CICU) admission practices and the use of critical care restricted therapies (CCRx), but little is known about the differences in patient acuity, CCRx utilization, and the associated outcomes within tertiary centers. METHODS: The Critical Care Cardiology Trials Network is a multicenter registry of tertiary and academic CICUs in the United States and Canada that captured consecutive admissions in 2-month periods between 2017 and 2022. This analysis included 17 843 admissions across 34 sites and compared interhospital tertiles of CCRx (eg, mechanical ventilation, mechanical circulatory support, continuous renal replacement therapy) utilization and its adjusted association with in-hospital survival using logistic regression. The Pratt index was used to quantify patient-related and institutional factors associated with CCRx variability. RESULTS: The median age of the study population was 66 (56-77) years and 37% were female. CCRx was provided to 62.2% (interhospital range of 21.3%-87.1%) of CICU patients. Admissions to CICUs with the highest tertile of CCRx utilization had a greater burden of comorbidities, had more diagnoses of ST-elevation myocardial infarction, cardiac arrest, or cardiogenic shock, and had higher Sequential Organ Failure Assessment scores. The unadjusted in-hospital mortality (median, 12.7%) was 9.6%, 11.1%, and 18.7% in low, intermediate, and high CCRx tertiles, respectively. No clinically meaningful differences in adjusted mortality were observed across tertiles when admissions were stratified by the provision of CCRx. Baseline patient-level variables and institutional differences accounted for 80% and 5.3% of the observed CCRx variability, respectively. CONCLUSIONS: In a large registry of tertiary and academic CICUs, there was a >4-fold interhospital variation in the provision of CCRx that was primarily driven by differences in patient acuity compared with institutional differences. No differences were observed in adjusted mortality between low, intermediate, and high CCRx utilization sites.

RESUMEN

Established in 2006, the Irish Longitudinal Study on Ageing (TILDA) investigates the health, economic and social circumstances of a nationally-representative sample of people aged fifty years and older in a series of biennial data collection waves. Irish newspapers have been reporting the results of TILDA for over a decade and a half, and their texts represent reports of scientific research distilled through the pen of journalists. In their totality, their texts constitute a public discourse on ageing and health. Using critical discourse analysis, we examined the discourse within the texts of a purposive sample of two national daily newspapers. As sites of public discourse, newspapers reflect social life and are influential in forming and legitimating public attitudes. Like other sites of discourse, their language-in-use is contextually located, is rarely neutral and may employ strategies to discursively construct, sustain and privilege particular social identities, including ageing identities. Discursively constructed as 'ageing well', our analysis of newspaper texts revealed a discernible meta-discourse on ageing and health in which ageing was framed as a life course stage that may be cultivated, diligently self-nurtured and exploited for its positive aspects. When considered in light of literature on health and social inequalities, the consequences of this broadly positive ageing discourse can, somewhat perversely, frame older adults in unintended negative ways, including homogenising them and attributing to them capacities for ageing well that they may not possess. Discursively constructing older adults as a social and economic resource can also impose unrealistic expectations on them and may legitimise exploitation and demonstrate how normative ideologies of ageism and ableism are conveyed through legitimising language. Despite these potentially unintended consequences, the available media resources associated with TILDA may represent one of the most important contributions of the study, in terms of informing positive public attitudes towards ageing.

RESUMEN

Background: Dementia research prioritisation allows for the systematic allocation of investment in dementia research by governments, funding agencies and the private sector. There is currently a lack of information available in Ireland regarding priority areas for dementia research. To address this gap, a dementia research prioritisation exercise was undertaken, consisting of an online survey of professionals in the dementia field and workshops for people living with dementia and family carers. Methods: (1) An anonymous online survey of professionals, based on an existing WHO global survey: the global survey was adapted to an Irish context and participants were asked to score 65 thematic research avenues under five criteria; (2) A mixed-methods exercise for people living with dementia and family carers: this involved two facilitated workshops where participants voted on the research themes they felt were important to them and should be addressed through research. Results: Eight of the top ten research priorities in the survey of professionals ( n=108) were focused on the delivery and quality of care and services for people with dementia and carers. Other research avenues ranked in the top ten focused on themes of timely and accurate diagnosis of dementia in primary health-care practices and diversifying therapeutic approaches in clinical trials. Participants in the workshops ( n=13) ranked 'better drugs and treatment for people with dementia', 'dementia prevention/ risk reduction' and 'care for people with dementia and carers' as their top priority areas. Conclusions: Findings from this prioritisation exercise will inform and motivate policymakers, funders and researchers to support and conduct dementia-focused research and ensure that the limited resources made available are spent on research that has the most impact for those who will benefit from and use the results of research.

RESUMEN

Background: International policy is increasingly committed to placing interdisciplinary team-working at the centre of health and social care integration across the lifespan. The National Clinical Programme for Older People in Ireland has a critical role in the design and implementation of the National Older Person's Service Model, which aims to shift the delivery of care away from acute hospitals towards community-based care. Interdisciplinary Community Specialist Teams for older persons (CST-OPs) play an important role in this service model. To support the development of competencies for interprofessional collaboration and an interdisciplinary team-based approach to care integration, a culture shift will be required within care delivery. Design:This study builds upon a collaborative partnership project which co-designed a framework describing core competencies for interprofessional collaboration in CST-OPs. A realist-informed process evaluation of the framework will be undertaken as the competencies described in the framework are being fostered in newly developed CST-OPs under the national scale-up of the service model. Realist evaluation approaches reveal what worked, why it worked (or did not), for whom and under what circumstances. Three iterative and integrated work packages are proposed which combine multiple methods of data collection, analysis and synthesis. Prospective data collection will be undertaken within four CST-OPs, including qualitative exploration of the care experiences of older people and family carers. Discussion: The realist explanatory theory will provide an understanding of how interprofessional collaboration can be fostered and sustained in various contexts of care integration for older people. It will underpin curriculum development for team-based education and training of health and social care professionals, a key priority area in the national Irish health strategy. It will provide healthcare leaders with knowledge of the resources and supports required to harness the benefits of interprofessional collaboration and to realise the goals of integrated care for older people.

RESUMEN

BACKGROUND: Fatigue and burnout are prevalent among resident physicians across Canada. Shifts exceeding 24 hours are commonly purported as detrimental to resident health and performance. Residency training programs have employed strategies towards understanding and intervening upon the complex issue of resident fatigue, where alternative resident scheduling models have been an area of active investigation. This study sought to characterize drivers and outcomes of fatigue and burnout amongst internal medicine residents across different scheduling models. METHODS: We conducted cross-sectional surveys were among internal medicine resident physicians at the University of Alberta. We collected anonymized socioeconomic demographics and medical education background, and estimated associations between demographic or work characteristics and fatigue and burnout outcomes. RESULTS: Sixty-nine participants competed burnout questionnaires, and 165 fatigue questionnaires were completed (response rate of 48%). The overall prevalence of burnout was 58%. Lower burnout prevalence was noted among respondents with dependent(s) (p = 0.048), who identified as a racial minority (p = 0.018), or completed their medical degree internationally (p = 0.006). The 1-in-4 model was associated with the highest levels of fatigue, reported increased risk towards personal health (OR 4.98, 95%CI 1.77-13.99) and occupational or household harm (OR 5.69, 95%CI 1.87-17.3). Alternative scheduling models were not associated with these hazards. CONCLUSIONS: The 1-in-4 scheduling model was associated with high rates of resident physician fatigue, and alternative scheduling models were associated with less fatigue. Protective factors against fatigue are best characterized as strong social supports outside the workplace. Further studies are needed to characterize the impacts of alternative scheduling models on resident education and patient safety.

RESUMEN

INTRODUCTION: Supported (assisted) healthcare decision-making (ADM) focuses attention on how people with disabilities, including cognitive impairments, can be best supported to make decisions about their health and social care on an equitable basis with others. Meaningful implementation of legal frameworks for ADM challenges long-held presumptions about who has access to valued decision-making resources, influence and power within a particular socio-cultural setting. This study aims to explore the relational power dynamics around ADM with older people in acute care settings. METHODS: This study adopts a critical hermeneutic approach to qualitatively explore the lived experience of ADM from the perspectives of Health and Social Care Professionals (N = 26). This is supported by an exploration of the experiences of older people (N = 4), older people with a diagnosis of dementia (N = 4) and family carers (N = 5). RESULTS: We present three themes of data analysis that represent three spaces where the relational aspects of power in ADM are manifested. The first space, centralising decision-making power within multidisciplinary teams identified the privileging of physicians in traditional hierarchical leadership models that may lead to the implicit exclusion of family carers and some Health and Social Care Professionals in the ADM process. Privileging cognitive and communication competence identified a tendency to attribute decision-making autonomy to those with cognitive and communication competency. The final space, balancing the duty of care and individual autonomy, recognises acute care settings as typically risk-averse cultures that limit autonomy for decisions that carry risk, especially for those with cognitive impairment. CONCLUSION: Findings indicate the need to address cultural sources of power operating through social norms premised on ageist and ableist ideologies. It is necessary to challenge institutional barriers to meaningful ADM including positional power that is associated with hierarchies of influence and protectionism. Finally, meaningful ADM requires resistance to the disempowerment created by structural, economic and social circumstances which limit choices for decision-making. PATIENT OR PUBLIC CONTRIBUTION: A public and patient involvement panel of older people were consulted in the development of the grant application (HRB: APA-2016-1878). Representatives from Alzheimer's Society Ireland and Family Carers Ireland were steering committee members guiding design and strategy.

RESUMEN

Current evidence offers little guidance as to how interprofessional collaboration can be fostered within the context of integrated care and older people. This research describes the co-design of core competencies for interprofessional collaboration within integrated care teams for older people and the development of practical guidance to support teams in building proficiency. Using a co-design approach, we conducted three studies (co-design workshops, qualitative interviews, and an online validation forum), the combined output of which is a Core Competency Framework, that includes three domains describing six competencies for proficiency in interprofessional collaboration within integrated care of older people. Domain one, Knowledge of the Team, includes the competencies; understanding roles, and making referrals. Domain two, Communication, includes the competencies; sharing information and communicating effectively and Domain three, Shared Decision-making, includes the final two competencies; supporting decision making with older people and collective clinical decision-making. In presenting a formal understanding of the competencies for interprofessional collaboration in the integrated care of older people and practical guidance for developing proficiency, this framework provides direction for future health service workforce development.

RESUMEN

Background: Approximately 480 people annually in Ireland are diagnosed with a primary brain tumour. Brain tumours are a heterogeneous group of conditions, varying in histopathology, location, and progression. A consistent feature is neurological impairment, which can lead to profound effects on physical and cognitive function. There is evidence that people with brain tumours can benefit from rehabilitation, but pathways are poorly described, and no best practice is defined. This leads to significant unmet need. The aim of this study is to understand the rehabilitation needs of people diagnosed with a brain tumour in Ireland, and gain insight to inform policy and practice. Methods: A prospective, mixed methods study with embedded action research will be conducted. Patients (n=122) with a new diagnosis of primary brain tumour, and optionally, a nominated carer or family member, will be recruited through a national neuro-oncology service. Rehabilitation need (Mayo-Portland Adaptability Inventory), quality of life (European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Brain Cancer Module, EuroQol-5D-5L), healthcare utilisation and, optionally, carer needs (Carer Support Needs Assessment Tool) will be assessed at four, eight and 12 months post diagnosis. An embedded qualitative study will invite 30 patients and carers to a semi-structured interview to explore their lived experience of rehabilitation needs and services following brain tumour diagnosis. Finally, using an Action Research approach, healthcare professionals involved in caring for people with brain tumours will be invited to participate in co-operative inquiry groups, to reflect on emerging aggregate findings and identify actions that could be undertaken while the study is underway. Conclusions: By understanding rehabilitation need, the findings will help healthcare professionals and health service providers understand how to prioritise the supports required and encourage policy makers to adequately resource neurorehabilitation to meet the needs of people with a brain tumour diagnosis.

RESUMEN

Introduction: Frequent asthma attacks in children result in unscheduled hospital presentations. Patient centered care coordination can reduce asthma hospital presentations. In 2016, The Sydney Children's Hospitals Network launched the Asthma Follow up Integrated Care Initiative with the aim to reduce pediatric asthma emergency department (ED) presentations by 50% through developing and testing an integrated model of care led by care coordinators (CCs). Methods: The integrated model of care was developed by a multidisciplinary team at Sydney Children's Hospital Randwick (SCH,R) and implemented in two phases: Phase I and Phase II. Children aged 2-16 years who presented ≥4 times to the ED of the SCH,R in the preceding 12 months were enrolled in Phase I and those who had ≥4 ED presentations and ≥1 hospital admissions with asthma attack were enrolled in Phase II. Phase I included a suite of interventions delivered by CCs including encouraging parents/carers to schedule follow-up visits with GP post-discharge, ensuring parents/carers are provided with standard asthma resource pack, offering referrals to asthma education sessions, sending a letter to the child's GP advising of the child's recent hospital presentation and coordinating asthma education webinar for GPs. In addition, in Phase II CCs sent text messages to parents/carers reminding them to follow-up with the child's GP. We compared the change in ED visits and hospital admissions at baseline (6 months pre-enrolment) and at 6-and 12-months post-enrolment in the program. Results: During December 2016-January 2021, 160 children (99 in Phase I and 61 in Phase II) were enrolled. Compared to baseline at 6- and 12-months post-enrolment, the proportion of children requiring ≥1 asthma ED presentations reduced by 43 and 61% in Phase I and 41 and 66% in Phase II. Similarly, the proportion of children requiring ≥1 asthma hospital admissions at 6- and 12-months post-enrolment reduced by 40 and 47% in Phase I and 62 and 69% in Phase II. Conclusion: Our results support that care coordinator led integrated model of asthma care which enables integration of acute and primary care services and provides families with asthma resources and education can reduce asthma hospital presentations in children.

RESUMEN

Meaningful and inclusive involvement of all people affected by research in the design, management and dissemination of that research requires skills, time, flexibility and resources. There continue to be research practices that create implicit and explicit exclusion of some members of the public who may be 'seldom heard' or 'frequently ignored'. Our focus is particularly on the involvement of people living with cognitive impairment, including people with one of the many forms of dementia and people with learning disabilities. We reflect especially on issues relating to the precommencement stage of research. We suggest that despite pockets of creative good practice, research culture remains a distinct habitus that continues to privilege cognition and articulacy in numerous ways. We argue that in perpetuating this system, some researchers and the institutions that govern research are committing a form of bureaucratic violence. We call for a reimagining of the models of research governance, funding and processes to incorporate the time and flexibility that are essential for meaningful involved research, particularly at the precommencement stage. Only then will academic health and social science research that is truly collaborative, engaged, accessible and inclusive be commonplace. PUBLIC AND PATIENT CONTRIBUTION: This viewpoint article was written by a research network of academics with substantial experience in undertaking and researching patient and public involvement and codesign work with representatives of the public and patients right across the health system. Our work guided the focus of this viewpoint as we reflected on our experiences.

RESUMEN

Many countries face major challenges to ensure that their health and social care systems are ready for the growing numbers of older people (OP). As a way of realising ageing in place, assistive technologies such as home-care robots are expected to play a greater role in the future. In Asia and Europe, robots are gradually being adopted as a public policy solution to the workforce shortage. Yet, there is still a strongly held belief that such technologies should not be part of human and personal care services such as OP's care. However, there has been little research into attitudes and perceptions of potential users regarding home-care robots which can provide companionship and support with activities of daily living. To explore these in more detail, a questionnaire study was carried out in Finland, Ireland and Japan. This study reports findings from the Irish cohort (114 older people [OP], 8 family carers and 56 Health and Social Care Professionals [HSCPs]). Seventy per cent of the total respondents (N = 178) reported being open to the use of home-care robots, and only one quarter had a negative image of robots. People with care responsibilities in their private capacity expressed more interest in, and readiness to use, home-care robots, while stressing the importance of 'privacy protection' and 'guaranteed access to human care'. Both OP and HSCPs identified observation and recording of OP's mental and physical condition as desirable functions of such robots, whereas practical functions such as fall prevention and mobility support were also deemed desirable by HSCPs. There is generally positive interest in home-care robots among Irish respondents. Findings strongly suggest that the interest is generated partly by great need among people who deliver care. Should such robots be developed, then careful consideration must be given to user-centred design, ethical aspects and national care policy.

RESUMEN

In this study, we aimed to identify acute respiratory distress syndrome (ARDS) metabolic fingerprints in selected patient cohorts and compare the metabolic profiles of direct versus indirect ARDS and hypoinflammatory versus hyperinflammatory ARDS. We hypothesized that the biological and inflammatory processes in ARDS would manifest as unique metabolomic fingerprints that set ARDS apart from other intensive care unit (ICU) conditions and could help examine ARDS subphenotypes and clinical subgroups. Patients with ARDS (n = 108) and ICU ventilated controls (n = 27) were included. Samples were randomly divided into 2/3 training and 1/3 test sets. Samples were analyzed using 1H nuclear magnetic resonance spectroscopy and gas chromatography-mass spectrometry. Twelve proteins/cytokines were also measured. Orthogonal partial least squares discriminant analysis (OPLS-DA) was used to select the most differentiating ARDS metabolites and protein/cytokines. Predictive performance of OPLS-DA models was measured in the test set. Temporal changes of metabolites were examined as patients progressed through ARDS until clinical recovery. Metabolic profiles of direct versus indirect ARDS subgroups and hypoinflammatory versus hyperinflammatory ARDS subgroups were compared. Serum metabolomics and proteins/cytokines had similar area under receiver operator curves when distinguishing ARDS from ICU controls. Pathway analysis of ARDS differentiating metabolites identified a dominant involvement of serine-glycine metabolism. In longitudinal tracking, the identified pathway metabolites generally exhibited correction by 7-14 days, coinciding with clinical improvement. ARDS subphenotypes and clinical subgroups were metabolically distinct. However, our identified metabolic fingerprints are not ARDS diagnostic biomarkers, and further research is required to ascertain generalizability. In conclusion, patients with ARDS are metabolically different from ICU controls. ARDS subphenotypes and clinical subgroups are metabolically distinct.

RESUMEN

Four manufacturing impurities of D&C Red No. 33 isolated by counter-current chromatography were analyzed by NMR and ESI mass spectrometry. Three of these impurities were reported previously with minimal details of structural determination. All four are structurally related to the main component of the dye. The fourth exhibited an unusual discrepancy between the NMR structure and its chemical formula suggested by ESI-MS results. Structural determination and assignment of the main component and four impurities are discussed as well as resolution of the discrepancy between the NMR and ESI-MS results of the fourth impurity.

RESUMEN

In recent years, there has been a move toward a more human rights-based approach to the issue of supported and assisted decision-making (ADM) with legislative changes strengthening the formal right for older people to participate in care planning and decision-making. Ireland's Assisted Decision-Making (Capacity) Act, 2015 breaks from traditional views of capacity to consider the uniqueness of each decision in relation to topic, time and place for those with impaired or fluctuating capacity. This study set out to explore experiences of assisted decision making (ADM) in acute care hospitals in Ireland and to identify the barriers and enablers to ADM for older people and people with dementia from the perspective of different Health and Social Care Professionals (HSCPs) involved in their care. We carried out 26 semi-structured audio-recorded interviews with a convenience sample of HSCPs working in two acute hospitals and subsequently confirmed the results. HSCPs identified several barriers to, and enablers of, ADM in acute hospitals that were categorized into three key themes: Building meaningful engagement with older people and their family carers; barriers and enablers associated with interprofessional collaboration and barriers and enablers associated with the environment. Our findings suggest that despite concrete policy and legislative underpinnings to ADM, this was not always evident in practice and suggests the need for specialized education and training on ADM in practice settings.

RESUMEN

OBJECTIVE: The immediate signals that couple exercise to metabolic adaptations are incompletely understood. Nicotinamide adenine dinucleotide phosphate oxidase 4 (Nox4) produces reactive oxygen species (ROS) and plays a significant role in metabolic and vascular adaptation during stress conditions. Our objective was to determine the role of Nox4 in exercise-induced skeletal muscle metabolism. METHODS: Mice were subjected to acute exercise to assess their immediate responses. mRNA and protein expression responses to Nox4 and hydrogen peroxide (H2O2) were measured by qPCR and immunoblotting. Functional metabolic flux was measured via ex vivo fatty acid and glucose oxidation assays using 14C-labeled palmitate and glucose, respectively. A chronic exercise regimen was also utilized and the time to exhaustion along with key markers of exercise adaptation (skeletal muscle citrate synthase and beta-hydroxyacyl-coA-dehydrogenase activity) were measured. Endothelial-specific Nox4-deficient mice were then subjected to the same acute exercise regimen and their subsequent substrate oxidation was measured. RESULTS: We identified key exercise-responsive metabolic genes that depend on H2O2 and Nox4 using catalase and Nox4-deficient mice. Nox4 was required for the expression of uncoupling protein 3 (Ucp3), hexokinase 2 (Hk2), and pyruvate dehydrogenase kinase 4 (Pdk4), but not the expression of peroxisome proliferator-activated receptor gamma coactivator 1-alpha (Pgc-1α). Global Nox4 deletion resulted in decreased UCP3 protein expression and impaired glucose and fatty acid oxidization in response to acute exercise. Furthermore, Nox4-deficient mice demonstrated impaired adaptation to chronic exercise as measured by the time to exhaustion and activity of skeletal muscle citrate synthase and beta-hydroxyacyl-coA-dehydrogenase. Importantly, mice deficient in endothelial-Nox4 similarly demonstrated attenuated glucose and fatty acid oxidation following acute exercise. CONCLUSIONS: We report that H2O2 and Nox4 promote immediate responses to exercise in skeletal muscle. Glucose and fatty acid oxidation were blunted in the Nox4-deficient mice post-exercise, potentially through regulation of UCP3 expression. Our data demonstrate that endothelial-Nox4 is required for glucose and fatty acid oxidation, suggesting inter-tissue cross-talk between the endothelium and skeletal muscle in response to exercise.

RESUMEN

The Coronavirus pandemic and associated measures for the protection of the public have impacted differently on different parts of the population and across different nations. In many areas, COVID-19 has also either exacerbated already existing or created new inequalities in relation to specific parts of the population. Older individuals are one group in society that has been widely impacted, while social isolation/shielding measures have placed them in higher risk of loneliness, isolation, financial deprivation and mental health challenges, to name a few. This commentary reflects on such inequalities across four European nations (the United Kingdom (UK), Republic of Ireland, Finland, Spain) and draws attention to the critical role of Gerontological Social Work (GSW), while emphasizing the ways in which social work can intervene. First, we identify common concerns for the rights of older people that span across all four nations, and second, we identify significant roles for GSW practitioners at the individual, community and policy levels and conclude with a call for GSW in these four nations to be reimagined in a time of global crisis.

RESUMEN

BACKGROUND: The University College Dublin (UCD) Public and Patient Invovlement (PPI) ignite program is focused on embedding PPI in health and social care related research, education and training, professional practice and administration. During a PPI knowledge sharing event challenges were noted during the pre-commencement stage of research projects. This stage includes the time before a research projects/partnership starts or when funding is being applied for. As a response, we agreed there was a need to spend time developing a values-based approach to be used from the pre-commencement of PPI projects and partnerships. Values are deeply held ideals that people consider to be important. They are vital in shaping our attitudes and motivating our choices and behaviours. METHODS: Using independent facilitators, we invited a diverse group of participants to a full-day workshop in February. During the workshop, the concept of a values statement and values-based approaches was introduced. The group via a majority consensus, agreed on a core set of values and a shared understanding of them. After the workshop, a draft was shared with participants for further comment and final agreement. RESULTS: The workshop had 22 people representing experts by experience, PPI charity partners, funders, academics and national PPI Ignite partners. The group via consensus identified four values of respect, openness, reciprocity and flexibility for the pre-commencement stage. A frequently reported experience of PPI partners was that some felt that the pre-commencement activities appeared at times like a performance; an act that had to be completed in order to move to the next stage rather than a genuine interest in a mutually beneficial partnership. Being open and transparent with all invovled that the funding application may not be successful was stressed. Another important feature related to 'openness' was the 'spaces' and 'places' in which meetings between partners could occur in an accessible and equitable way. The issue of 'space' is particularly critical for the involvement of seldom heard groups. The benefits of the research are often clear for academics, but for PPI partners, these are often less certain. To achieve reciprocity, academic and PPI partners need to engage in a timely, repeated and transparent dialogue to achieve beneficial outcomes for all stakeholders. Being open to new inputs and differing modes of knowledge and ideas was also stressed. For some, this will require a change in attitudes and behaviours and should result in more collective decision making. Several areas were identified using the four values. CONCLUSIONS: This work via majority consensus identified four values of respect, openness, reciprocity, and flexibility for the pre-commencement stage. These values should be used to support inclusive, effective and collective PPI across all stages of involvement. We hope this work will stimulate further action in this area. In particular, we would welcome the evaluation of these values involving diverse PPI groups.

RESUMEN

Background: The National Integrated Care Programme for Older People (NICPOP), formerly NCPOP aims to support older people to live well in their homes by developing primary and secondary care services for older people, especially those with complex needs. The programme develops integrated intermediate care which traverses both hospital and community settings through multidisciplinary and interagency teams. This team-based approach to the integration of health services is a novel innovation in Irish health service delivery and will require, over time, a shift in cultures of care to allow for the development of competencies for inter-professional collaboration across the care continuum. The ECLECTIC project will develop an implementation framework for achieving, maintaining and monitoring competencies for interprofessional collaboration among multi-disciplinary teams charged with delivering care for older people across the continuum from acute to community settings. Design: The ECLECTIC research design has been developed in collaboration with the NICPOP. In phase one of the project, a co-design team will collaborate to define and shape competencies for interprofessional collaboration. Phase two will involve the delivery of a collective leadership intervention over a 10-month period with multidisciplinary professionals working with older people across two geographical regions (Mullingar/Midlands and Beaumont/Dublin North). Each group will comprise of members of two multidisciplinary teams charged with coordinating and delivering care to older people across the continuum of acute to community care. Observations of collaborative inter-professional working will take place before, during, and after intervention. In phase three of the study, analysis of the interview and observation data will be presented to the co-design team in order to develop an implementation framework for future teams. Discussion: The co-design process will develop core competencies and performance indicators for collaborative interprofessional working. The resulting implementation framework will be implemented nationally as part of the NICPOP.

RESUMEN

PURPOSE: To clarify potential users' perceptions toward the development and social implementation of home-care robots in Japan, Ireland, and Finland. METHODS: Unsigned, self-administered questionnaires were distributed to adults aged 65 or older, family caregivers, and home-care/health and social care professionals (HSCPs). A total of 1004 responses were collected. RESULTS: In Japan, many people were already familiar with robots in their daily lives. The most notable finding about their perspectives on home-care robots was related to safety. Moreover, 93.7 % of the Japanese respondents said, "If the user cannot decide whether to use a home-care robot, family members who know the user well should decide," followed by 76.4 % in Ireland and 83.1 % in Finland (p < .001). In Ireland, 81.8 % of the respondents said, "I want to help other people and society by participating in the research and development of home-care robots" (Japan: 69.9 %; Finland: 67.5 %) (p = .006). In Finland, many people had a negative impression of robots compared to the other two countries. Finland had the highest percentage (75.4 %) of respondents who said, "Health care professionals should be allowed to use secondary information collected by a home-care robot" (Japan and Ireland: 64 %) (p = .024). Moreover, Ireland and Finland emphasized the need to guarantee the entitlement to receive human care. CONCLUSIONS: Devising optimal strategies for the development and social implementation of home-care robots by incorporating various perspectives while valuing human dignity will require examination of each country's characteristics with respect to history, culture, policies, and values related to robots.

RESUMEN

OBJECTIVE: The Assisted Decision-Making (ADM) (Capacity) Act was enacted in 2015 in Ireland and will be commenced in 2021. This paper is focused on this pre-implementation stage within the acute setting and uses a health systems responsiveness framework. METHODS: We conducted face-to-face interviews using a critical incident technique. We interviewed older people including those with a diagnosis of dementia (n = 8), family carers (n = 5) and health and social care professionals (HSCPs) working in the acute setting (n = 26). RESULTS: The interviewees reflected upon a healthcare system that is currently under significant pressures. HSCPs are doing their best, but they are often halted from delivering on the will and preference of their patients. Many older people and family carers feel that they must be very assertive to have their preferences considered. All expressed concern about the strain on the healthcare system. There are significant environmental barriers that are hindering ADM practice. CONCLUSIONS: The commencement of ADM provides an opportunity to redefine the provision, practices, and priorities of healthcare in Ireland to enable improved patient-centred care. To facilitate implementation of ADM, it is therefore critical to identify and provide adequate resources and work towards solutions to ensure a seamless commencement of the legislation.
