Achievement of Target Gain Larger than Unity in an Inertial Fusion Experiment

On December 5, 2022, an indirect drive fusion implosion on the National Ignition Facility (NIF) achieved a target gain G_{target} of 1.5. This is the first laboratory demonstration of exceeding "scientific breakeven" (or G_{target}>1) where 2.05 MJ of 351 nm laser light produced 3.1 MJ of total fusion yield, a result which significantly exceeds the Lawson criterion for fusion ignition as reported in a previous NIF implosion [H. Abu-Shawareb et al. (Indirect Drive ICF Collaboration), Phys. Rev. Lett. 129, 075001 (2022)PRLTAO0031-900710.1103/PhysRevLett.129.075001]. This achievement is the culmination of more than five decades of research and gives proof that laboratory fusion, based on fundamental physics principles, is possible. This Letter reports on the target, laser, design, and experimental advancements that led to this result.

A nurturing and caring environment to facilitate nursing students' professional development in Rwanda: a focused ethnographic study

OBJECTIVES

To explore the values, practices, and behaviours that support nursing students' professional development in practice-based learning environments in Rwanda.

METHODS

A focused ethnographic approach was used. Nursing students (n=12), nurses (n=11), clinical instructors (n=7) and nurse leaders (n=8) from three teaching hospitals and an educational program participated in the study. Data was collected trough individual interviews and participant observation.

RESULTS

Participants embraced a culture of preparing nursing students for their professional roles as a professional responsibility, and a means of securing the nursing profession. Modeling the appropriate behaviours to students and respecting them as learners and humans constituted the caring attributes that sustain a positive learning environment for their professional growth.

CONCLUSIONS

Nurturing and caring environments offer students opportunities to integrate caring attitudes into their interactions with patients and to develop professionally.

IMPLICATIONS FOR INTERNATIONAL AUDIENCE

Findings underscore the need to enhance caring values within nursing curricula.

Cohort profile: the ESC EURObservational Research Programme Non-ST-segment elevation myocardial infraction (NSTEMI) Registry

AIMS

The European Society of Cardiology (ESC) EURObservational Research Programme (EORP) Non-ST-segment elevation myocardial infarction (NSTEMI) Registry aims to identify international patterns in NSTEMI management in clinical practice and outcomes against the 2015 ESC Guidelines for the management of acute coronary syndromes in patients presenting without ST-segment-elevation.

METHODS AND RESULTS

Consecutively hospitalised adult NSTEMI patients (n = 3620) were enrolled between 11 March 2019 and 6 March 2021, and individual patient data prospectively collected at 287 centres in 59 participating countries during a two-week enrolment period per centre. The registry collected data relating to baseline characteristics, major outcomes (in-hospital death, acute heart failure, cardiogenic shock, bleeding, stroke/transient ischaemic attack, and 30-day mortality) and guideline-recommended NSTEMI care interventions: electrocardiogram pre- or in-hospital, pre-hospitalization receipt of aspirin, echocardiography, coronary angiography, referral to cardiac rehabilitation, smoking cessation advice, dietary advice, and prescription on discharge of aspirin, P2Y12 inhibition, angiotensin converting enzyme inhibitor (ACEi)/angiotensin receptor blocker (ARB), beta-blocker, and statin.

CONCLUSION

The EORP NSTEMI Registry is an international, prospective registry of care and outcomes of patients treated for NSTEMI, which will provide unique insights into the contemporary management of hospitalised NSTEMI patients, compliance with ESC 2015 NSTEMI Guidelines, and identify potential barriers to optimal management of this common clinical presentation associated with significant morbidity and mortality.

3D Simulations Capture the Persistent Low-Mode Asymmetries Evident in Laser-Direct-Drive Implosions on OMEGA

Spherical implosions in inertial confinement fusion are inherently sensitive to perturbations that may arise from experimental constraints and errors. Control and mitigation of low-mode (long wavelength) perturbations is a key milestone to improving implosion performances. We present the first 3D radiation-hydrodynamic simulations of directly driven inertial confinement fusion implosions with an inline package for polarized crossed-beam energy transfer. Simulations match bang times, yields (separately accounting for laser-induced high modes and fuel age), hot spot flow velocities and direction, for which polarized crossed-beam energy transfer contributes to the systematic flow orientation evident in the OMEGA implosion database. Current levels of beam mispointing, imbalance, target offset, and asymmetry from polarized crossed-beam energy transfer degrade yields by more than 40%. The effectiveness of two mitigation strategies for low modes is explored.

Lawson Criterion for Ignition Exceeded in an Inertial Fusion Experiment

For more than half a century, researchers around the world have been engaged in attempts to achieve fusion ignition as a proof of principle of various fusion concepts. Following the Lawson criterion, an ignited plasma is one where the fusion heating power is high enough to overcome all the physical processes that cool the fusion plasma, creating a positive thermodynamic feedback loop with rapidly increasing temperature. In inertially confined fusion, ignition is a state where the fusion plasma can begin "burn propagation" into surrounding cold fuel, enabling the possibility of high energy gain. While "scientific breakeven" (i.e., unity target gain) has not yet been achieved (here target gain is 0.72, 1.37 MJ of fusion for 1.92 MJ of laser energy), this Letter reports the first controlled fusion experiment, using laser indirect drive, on the National Ignition Facility to produce capsule gain (here 5.8) and reach ignition by nine different formulations of the Lawson criterion.

Sugar or salt ("SOS"): A protocol for a UK multicentre randomised trial of mannitol and hypertonic saline in severe traumatic brain injury and intracranial hypertension

Hyperosmolar solutions are widely used to treat raised intracranial pressure following severe traumatic brain injury. Although mannitol has historically been the most frequently administered, hypertonic saline solutions are increasingly being used. However, definitive evidence regarding their comparative effectiveness is lacking. The Sugar or Salt Trial is a UK randomised, allocation concealed open label multicentre pragmatic trial designed to determine the clinical and cost-effectiveness of hypertonic saline compared with mannitol in the management of patients with severe traumatic brain injury. Patients requiring intensive care unit admission and intracranial pressure monitoring post-traumatic brain injury will be allocated at random to receive equi-osmolar boluses of either mannitol or hypertonic saline following failure of routine first-line measures to control intracranial pressure. The primary outcome for the study will be the Extended Glasgow Outcome Scale assessed at six months after randomisation. Results will inform current clinical practice in the routine use of hyperosmolar therapy as well as assess the impact of potential side effects. Pre-planned longer term clinical and cost effectiveness analyses will further inform the use of these treatments.

Rare musculoskeletal diseases in adults: a research priority setting partnership with the James Lind Alliance

BACKGROUND

Osteogenesis imperfecta, fibrous dysplasia/McCune-Albright syndrome and X-linked hypophosphatemia are three rare musculoskeletal diseases characterised by bone deformities, frequent fractures and pain. Little high-quality research exists on appropriate treatment and long-term management of these conditions in adults. This is further worsened by limited research funding in rare diseases and a general mismatch between the existing research priorities and those of the patients. This partnership adopted the James Lind Alliance approach to identify the top 10 research priorities for rare musculoskeletal diseases in adults through joint patient, carer and healthcare professional collaboration.

RESULTS

The initial survey for question collection recruited 198 respondents, submitting a total of 988 questions. 77% of the respondents were patients with a rare musculoskeletal disease. Following out-of-scope question exclusion, repeating query grouping and scientific literature check for answers, 39 questions on treatment and long-term management remained. In the second public survey, 220 respondents, of whom 85% were patients with a rare musculoskeletal disease, their carers, relatives or friends, prioritised these uncertainties, which allowed selection of the top 25. In the last stage, patients, carers and healthcare professionals gathered for a priority setting workshop to reach a consensus on the final top 10 research priorities. These focus on the uncertainties surrounding appropriate treatment and holistic long-term disease management, highlighting several aspects indirect to abnormal bone metabolism, such as extra-skeletal symptoms, psychological care of both patients and their families and disease course through ageing.

CONCLUSIONS

This James Lind Alliance priority setting partnership is the first to investigate rare bone diseases. The priorities identified here were developed jointly by patients, carers and healthcare professionals. We encourage researchers, funding bodies and other stakeholders to use these priorities in guiding future research for those affected by rare musculoskeletal disorders.

Predicting Registered Nurses' Behavioural Intention to Use Electronic Documentation System in Home Care: Application of an Adapted Unified Theory of Acceptance and Use of Technology Model

The use of electronic documentation systems (EDS) has the potential to ensure timely, up-to-date and comprehensive patient health-related information is available and accessible to nurses regardless of their physical location. Despite the benefits of EDS, nurses' low intention to use such systems is well documented, which may predict behavioural usage. Further, limited knowledge exists about nurses' intention to use EDS in the context of home care. The aim of the study was to examine factors that influence nurses' intention of using EDS in home care practice. The conceptual model framing this study is adapted from the Unified Theory of Acceptance and Use of Technology (UTAUT). A cross-sectional design was used. Nurses (N = 217) currently practicing within the home care sector in Ontario participated in the study. An online survey using adapted and psychometrically sound quantitative instruments was administered. Data were analyzed with descriptive statistics and hierarchical linear regression. Performance expectancy, attitude, social influence and facilitating conditions had significant, positive and direct effects on nurses' behavioural intention. Effort expectancy and nurses' individual characteristics (i.e., age, level of education and technology experience) were not found to have a direct and/or moderating influence on nurses' intention to use EDS in home care practice. Theory, practice and research implications for the findings are presented and discussed.

Caring Near and Far by Connecting Community-Based Clients and Family Member/Friend Caregivers Using Passive Remote Monitoring: Protocol for a Pragmatic Randomized Controlled Trial

Background

Significant chronic disease challenges exist among older adults. However, most older adults want to remain at home even if their health conditions challenge their ability to live independently. Yet publicly funded home care resources are scarce, private home care is expensive, and family/friend caregivers have limited capacity. Many older adults with chronic illness would require institutional care without the support from family member/friend caregivers. This role raises the risk of physical health problems, stress, burnout, and depression. Passive remote monitoring (RM), the use of sensors that do not require any action by the individual for the system to work, may increase the older adult’s ability to live independently while also providing support and peace of mind to both the client and the family member/friend caregiver.

Objective

This paper presents the protocol of a study conducted in two provinces in Canada to investigate the impact of RM along with usual home care (the intervention) versus usual home care alone (control) on older adults with complex care. The primary outcome for this study is the occurrence of and time to events such as trips to emergency, short-term admission to the hospital, terminal admission to the hospital awaiting admission to long-term care, and direct admission to long-term care. The secondary outcomes for this study are (1) health care costs, (2) client functional status and quality of life in the home, (3) family/friend caregiver stress, and (4) family/friend caregiver functional health status.

Methods

The design for this study is an unblinded pragmatic randomized controlled trial (PRCT) with two parallel arms in two geographic strata (Ontario and Nova Scotia). Quantitative and qualitative methodologies will be used to address the study objectives. This PRCT is conceptually informed by the principles of client-centered care and viewing the family as the client and aims at providing supported self-management.

Results

This study is supported by the Canadian Institutes for Health Research. A primary completion date is anticipated in fall 2022.

Conclusions

Findings from this real-world rigorous randomized trial will support Canadian decision-makers, providers, and clients and their caregivers in assessing the health, well-being, and economic benefits and the social and technological challenges of integrating RM technologies to support older adults to stay in their home, including evaluating the impact on the burden of care experienced by family/friend caregivers. With an aging population, this technology may reduce institutionalization and promote safe and independent living for the elderly as long as possible.

Abstract 3348: Top 10 living with and beyond cancer research priorities

More and more people are living with the consequences of cancer and its treatment (living with and beyond cancer), yet the level of relevant research is low compared to other types of cancer research in the UK. NCRI aims to increase the level of research in this area and to ultimately improve the lives of those affected by cancer. Undefined research priorities in this broad area has been a barrier to research. The 2015 NHS Independent Cancer Taskforce report also recommends defining research priorities and to enable this research to happen. To address this barrier the NCRI has undertaken a James Lind Alliance Priority Setting Partnership (PSP) to identify priorities that matter most to people affected by cancer and the health and social care professionals.A PSP consists of patients and carers, health and social care professionals. PSPs have several stages and begin with a UK-wide survey to gather questions about uncertainties in living with and beyond cancer. Once the results were analysed, an interim exercise takes place to further prioritise the uncertainties. The last stage is a final workshop where partners debate and finally arrive at a top 10 list of shared uncertainties.The living with and beyond cancer PSP received 3500 questions submitted by people affected by cancer and healthcare professionals. Through a 18-month established rigorous process, the questions are prioritised down to the Top 10 living with and beyond cancer priorities for research in June 2018. This is the first time that clear research priorities have been identified in this area. They are the most impactful research questions that will help improve the lives of people affected by cancer. The Top 10 uncertainties will be publicised widely to ensure that researchers and those who fund research really understand what matters to people affected by cancer. The top uncertainties will be promoted to many research organizations and relevant funders in the UK. We anticipate they will directly influence future research.

Intra-articular anaesthesia of the equine stifle improves foot lameness

BACKGROUND

Equine diagnostic anaesthesia can be a useful tool in challenging lameness examinations. However, anaesthetics diffuse over time leading to nonspecific desensitisation of periarticular structures. Nerves that convey sensation from the distal limb to the central nervous system pass in close proximity to the caudal stifle joint capsule. Therefore, diffusion of intra-articular (IA) anaesthetics could cause inadvertent desensitisation of the distal limb resulting in a false diagnosis of stifle lameness.

OBJECTIVES

To determine if IA stifle anaesthesia can alleviate lameness originating in the distal limb.

STUDY DESIGN

Crossover experiment.

METHODS

Nine horses were fitted with a circumferential hoof clamp to induce a moderate unilateral hindlimb lameness. Intra-articular stifle anaesthesia was performed and gait was evaluated every 10 min during the 90-min trial using an inertial sensor system. Push-off and landing components of the lameness were assessed by measuring the mean inter-stride difference between the maximum and minimum heights of the pelvis respectively. Differences were compared using a Wilcoxon signed-rank test.

RESULTS

Overall, horses with hoof clamp-induced foot pain had a reduction in push-off lameness after IA stifle anaesthesia. The mean change in diffmax at 90 min was -4.3 mm (P = 0.005) for the experimental group vs. -2.3 mm (P = 0.2) for the control group. Lameness decreased over time, with an average improvement of 23% at 30 min, 33% at 60 min and 38% at 90 min. There was high inter-horse variability; 3/9 horses improved by ~50% within 30 min, while 2/9 improved by ~30% and 4/9 had minimal (<10%) or no improvement in lameness. Improvement after IA stifle anaesthesia was not related to the severity of baseline lameness (P = 0.3-0.7).

MAIN LIMITATIONS

Limited clinical applicability of our lameness induction model.

CONCLUSIONS

Intra-articular stifle anaesthesia reduces foot lameness in a third of horses by up to 50% within 30 min. Clinically, the results of IA stifle anaesthesia should be considered in the light of these findings before treatment recommendations are made, as additional diagnostics may be required to rule out pain originating in the distal limb.

A Qualitative Content Analysis of Nurses' Comfort and Employment of Workarounds With Electronic Documentation Systems in Home Care Practice

Background

Electronic documentation systems have the potential to assist registered nurses with timely access to patient health- and care-related information. Registered nurses are the largest users of electronic documentation systems; however, limited evidence exists about their comfort with electronic documentation system usage and the types of workarounds developed within the context of home care.

Aim

To explore home care registered nurses’ comfort with electronic documentation system usage and identify the types and reasons for the development and implementation of workarounds.

Methods

A cross-sectional survey design was employed to collect quantitative and qualitative data. A total of 217 home care registered nurses participated in the survey. Quantitative data were analyzed using descriptive statistics. Qualitative data were analyzed using inductive content analysis. Findings: Individual (e.g., registered nurses’ technology-related experience), technological (e.g., electronic documentation system design) and organizational (e.g. training) characteristics influenced registered nurses’ comfort with electronic documentation system usage. Furthermore, workarounds stemmed from the technological characteristics of the electronic documentation system.

Conclusion

Findings highlight the need for assessing registered nurses’ level of comfort with electronic documentation system usage to inform training initiatives. Including registered nurses in the system design is advocated to ensure electronic documentation systems fit with the complexity of nursing practice, potentially enhancing registered nurses’ level of comfort and mitigating the development and employment of workarounds during system usage.

Predictors of new graduate nurses' health over the first 4 years of practice

AIM

To examine predictors of Canadian new graduate nurses' health outcomes over 1 year.

DESIGN

A time-lagged mail survey was conducted.

METHOD

New graduate nurses across Canada (N = 406) responded to a mail survey at two time points: November 2012-March 2013 (Time 1) and May-July 2014 (Time 2). Multiple linear regression (mental and overall health) and logistic regression (post-traumatic stress disorder risk) analyses were conducted to assess the impact of Time 1 predictors on Time 2 health outcomes.

RESULTS

Both situational and personal factors were significantly related to mental and overall health and post-traumatic stress disorder risk. Regression analysis identified that cynicism was a significant predictor of all three health outcomes, while occupational coping self-efficacy explained unique variance in mental health and work-life interference explained unique variance in post-traumatic stress disorder risk.

Social Media Technology and Public Health in Ontario: Findings from a Planning Meeting Exploring Current Practices and Future Research Directions

In the province of Ontario, many of the public health units (PHUs) now possess and use social media as part of their daily health promotion and communication operations. To explore this topic, a planning meeting was held to generate deeper insights toward the use of these forms of technology for preventative services delivery. The planning meeting was held with 50 participants, comprising representatives from 20 of the 36 PHUs in Ontario, interested academics, students and government representatives. A nominal group technique (NGT) was used to build consensus related to future research needs, as related to public health and social media. Participants generated a range of insights around the use of social media, including the need for: leadership buy-in and resource allocation; social media policy and governance structure; performance measurement and evaluation; practices related to engagement with program recipients and addressing the lack of resources faced by many health units. Future research priorities were also generated, related to evaluating the cost-benefit of social media activities and understanding behaviour change implications. Further research is needed to evaluate the functionality, leadership and competency requirements and impact(s) of these new forms of health communication technology within public health service delivery.

Tokenism and Mending Fences: How Rural Male Farmers and Their Health Needs Are Discussed in Health Policy and Planning Documents

Rural male farmers (RMFs) are an understudied population with high mortality, morbidity and co-morbidities due to preventable injury, most of which occur on-farm. This study examines how RMFs and their health needs are discussed in Ontario rural health policy documents. A retrospective analysis of policy was conducted to analyze the content of Ontario rural healthcare policy documents published since 2006. Discussions of RMFs were categorized by two themes: tokenism and mending fences. Tokenism refers to RMFs' invisibility, except when farming stereotypes were used to describe rural areas. Mending fences captures the desire of rural communities to be included in healthcare decisions, and to position RMFs as key stakeholders for healthcare organizations to engage with to improve how they are perceived by rural communities. This study asserts that including RMFs in health policy formation can improve rural healthcare delivery and relationships between rural healthcare organizations and the communities they serve.

Youth Homelessness: The Impact of Supportive Relationships on Recovery

Background Homeless youth are the fastest growing sub-group within the homeless population. They face impaired access to health services and are often left unsupported. They lack social and family support or relationships with service providers. Unsupported homeless youth often become homeless adults. Purpose To test a model based on Peplau's Theory of Interpersonal Relations, examining the influence of a network of service providers, perceptions of social supports, and family relations on a homeless youth's perceptions of recovery. Methods This study is a secondary analysis and used a sample (n = 187) of data collected as part of the original Youth Matters in London study. A cross-sectional design was used to analyze the relationship between variables. Participants were interviewed at 6-month intervals over a 2.5-year period. Hierarchical multiple regression analysis was used. Results Network of service providers, perceived social supports, and perceived family relations explained 21.8% of the variance in homeless youth perceptions of recovery. Perceived social support and family relations were significantly, positively correlated to perceptions of recovery. Network of service providers was not significantly correlated to perceptions of recovery. Conclusions The findings suggest that stronger social supports and family relations may contribute to increased perceptions of recovery among homeless youth.

An integrative review of the influence of job strain and coping on nurses' work performance: Understanding the gaps in oncology nursing research

Nursing is known to be a stressful profession that can lead to physical and psychological health issues and behavioural problems. In oncology, workload among nurses is believed to be increasing in conjunction with rapidly increasing numbers of patients with cancer and staff shortages worldwide, therefore it is essential to sustain a quality oncology nurse workforce. Numerous studies have presented evidence on job strain, effects of coping strategies, and nurses' work performance within healthcare settings, but few have focused on oncology settings and none of these on nurses working in Saudi Arabia. The purpose of this review was to summarize empirical and theoretical evidence concerning job-related stressors in nurses, particularly oncology nurses, and the interrelationships among job strain, coping strategies, and work performance in this population. Search strategies identified studies published on studies in peer-reviewed journals from 2004 to 2016. Twenty-five nursing studies were found examining the relationships among the concepts of interest. Common job-related stressors among oncology nurses were high job demands, dealing with death/dying, lack of job control, and interpersonal conflicts at work. Job strain was found to be significantly linked to coping strategies, and negatively associated with work performance among nurses in general. There is no existing empirical evidence to support the relationship between coping strategies and work performance among oncology nurses. The present evidence is limited, and a considerable amount of research is required in the future to expand the oncology nursing literature. Research is needed to investigate job-related stressors and their effects on oncology nurses.

Starting Out: qualitative perspectives of new graduate nurses and nurse leaders on transition to practice

AIM

To describe new graduate nurses' transition experiences in Canadian healthcare settings by exploring the perspectives of new graduate nurses and nurse leaders in unit level roles.

BACKGROUND

Supporting successful transition to practice is key to retaining new graduate nurses in the workforce and meeting future demand for healthcare services.

METHOD

A descriptive qualitative study using inductive content analysis of focus group and interview data from 42 new graduate nurses and 28 nurse leaders from seven Canadian provinces.

RESULTS

New graduate nurses and nurse leaders identified similar factors that facilitate the transition to practice including formal orientation programmes, unit cultures that encourage constructive feedback and supportive mentors. Impediments including unanticipated changes to orientation length, inadequate staffing, uncivil unit cultures and heavy workloads.

CONCLUSIONS

The results show that new graduate nurses need access to transition support and resources and that nurse leaders often face organisational constraints in being able to support new graduate nurses.

IMPLICATIONS FOR NURSING MANAGEMENT

Organisations should ensure that nurse leaders have the resources they need to support the positive transition of new graduate nurses including adequate staffing and realistic workloads for both experienced and new nurses. Nurse leaders should work to create unit cultures that foster learning by encouraging new graduate nurses to ask questions and seek feedback without fear of criticism or incivility.

Identifying the most important outcomes for systematic reviews of interventions for rhinosinusitis in adults: working with Patients, Public and Practitioners

INTRODUCTION

Promoting the assessment of health interventions using outcomes that matter to patients and practitioners is a key principle of Cochrane. Cochrane UK therefore commissioned the OMIPP project: Outcomes that are Most Important for Patients, Public and Practitioners to identify the outcomes they felt most important and should be evaluated in Cochrane reviews of health interventions for Chronic Rhinosinusitis (CRS).

METHODOLOGY

Using direct emailing, social media and printed cards, an online survey was distributed to a wide range of people involved in the care of patients with CRS. Patients and practitioners were asked to list the 3 outcomes from treatments most important to them. Responses were analysed through development of a thematic framework based on the data.

RESULTS

Two hundred and thirty-five people completed the survey; 155 practitioners and 80 patients. Respondents provided 653 suggestions of important outcomes. 73% concerned symptoms of CRS, (nasal discharge or drip, facial pain, nasal blockage, headache, impaired sense of smell, congestion and breathing difficulties); 9% concerned quality of life, 4% reducing the need for further treatment and 4% side effects of treatment. Objective measurements of disease formed only 3% of responses. There was high level of agreement between patients and practitioners. Of 10 current Cochrane reviews on CRS, 9 include symptomatic outcomes identified by our survey as most important to patients and healthcare practitioners.

CONCLUSIONS

We have identified outcomes that both patients and their doctors consider should be included in reviews evaluating treatments of rhinosinusitis. We recommend that primary outcomes in future reviews focus on symptom-based outcomes. The ability to extract these data from relevant trials is dependent upon their inclusion in trials, and so it is important that building on this work a core outcome set for rhinosinusitis research is developed.

Moving towards a new vision: implementation of a public health policy intervention

Background

Public health systems in Canada have undergone significant policy renewal over the last decade in response to threats to the public’s health, such as severe acute respiratory syndrome. There is limited research on how public health policies have been implemented or what has influenced their implementation. This paper explores policy implementation in two exemplar public health programs -chronic disease prevention and sexually-transmitted infection prevention - in Ontario, Canada. It examines public health service providers’, managers’ and senior managements’ perspectives on the process of implementation of the Ontario Public Health Standards 2008 and factors influencing implementation.

Methods

Public health staff from six health units representing rural, remote, large and small urban settings were included. We conducted 21 focus groups and 18 interviews between 2010 (manager and staff focus groups) and 2011 (senior management interviews) involving 133 participants. Research assistants coded transcripts and researchers reviewed these; the research team discussed and resolved discrepancies. To facilitate a breadth of perspectives, several team members helped interpret the findings. An integrated knowledge translation approach was used, reflected by the inclusion of academics as well as decision-makers on the team and as co-authors.

Results

Front line service providers often were unaware of the new policies but managers and senior management incorporated them in operational and program planning. Some participants were involved in policy development or provided feedback prior to their launch. Implementation was influenced by many factors that aligned with Greenhalgh and colleagues’ empirically-based Diffusion of Innovations in Service Organizations Framework. Factors and related components that were most clearly linked to the OPHS policy implementation were: attributes of the innovation itself; adoption by individuals; diffusion and dissemination;the outer context – interorganizational networks and collaboration; the inner setting – implementation processes and routinization; and, linkage at the design and implementation stage.

Conclusions

Multiple factors influenced public health policy implementation. Results provide empirical support for components of Greenhalgh et al’s framework and suggest two additional components – the role of external organizational collaborations and partnerships as well as planning processes in influencing implementation. These are important to consider by government and public health organizations when promoting new or revised public health policies as they evolve over time. A successful policy implementation process in Ontario has helped to move public health towards the new vision.

Rural Men's Health, Health Information Seeking, and Gender Identities: A Conceptual Theoretical Review of the Literature

Beginning as early as 2009, recent shifts in Canadian health care delivery indicate that access to health information is essential to promote and maintain a healthy population. It is important to understand how and where various populations, such as underresourced rural populations, access health information so that public health agencies can develop and deliver appropriate information with, for, and in these contexts. There is a paucity of research that specifically examines how rural Canadian men seek health information; therefore, this review aimed to conceptualize this process based on three dynamic key constructs: health patterns of rural Canadians, health information-seeking behaviors, and rural gender identities. This conceptual theoretical literature review included 91 articles at the intersection of these three constructs. Discussion focuses on how residing in a rural region influences men's health and health care access. Health information-seeking behaviors are discussed in terms of social networks and framed with a rural context. Connell's theory of masculinity provides a useful approach to dissecting how rural men's gender identities influence their health attitudes, and how such attitudes are embedded in rural social and cultural norms. Each major construct-health in rural Canada, health information seeking, and rural gender identities-is discussed to highlight how specific embodiments of masculinity may promote and inhibit men's health information-seeking and positive health behaviors.

Research priorities for shoulder surgery: results of the 2015 James Lind Alliance patient and clinician priority setting partnership

OBJECTIVE

To run a UK based James Lind Alliance Priority Setting Partnership for 'Surgery for Common Shoulder Problems'.

SETTING

This was a nationally funded and conducted process. It was organised from a musculoskeletal research centre and Biomedical Research Unit in Oxford.

PARTICIPANTS

UK shoulder patients, carers and clinicians, involved in treating patients with shoulder pain and shoulder problems that might require surgery.

INTERVENTIONS

These were national electronic and paper surveys capturing treatment uncertainties that are important to shoulder patients, carers and clinicians.

OUTCOME MEASURES

The outcomes relevant to this study were the survey results and rankings.

RESULTS

The process took 18 months to complete, with 371 participants contributing 404 in scope questions. The James Lind process then produced a final 10 research priorities and uncertainties that relate to the scope of 'Surgery for Common Shoulder Problems'.

CONCLUSIONS

The final top 10 UK research priorities have been produced and are now being disseminated to partner organisations and funders to guide funding of shoulder research for the next 5-10 years on topics that are important to patients, their carers and clinicians.

Starting Out: A time-lagged study of new graduate nurses' transition to practice

BACKGROUND

As the nursing profession ages, new graduate nurses are an invaluable health human resource.

OBJECTIVES

The purpose of this study was to investigate factors influencing new graduate nurses' successful transition to their full professional role in Canadian hospital settings and to determine predictors of job and career satisfaction and turnover intentions over a one-year time period in their early employment.

DESIGN

A national two-wave survey of new graduate nurses across Canada.

PARTICIPANTS

A random sample of 3906 Registered Nurses with less than 3 years of experience currently working in direct patient care was obtained from the provincial registry databases across Canada. At Time 1, 1020 of 3743 eligible nurses returned completed questionnaires (usable response rate=27.3%). One year later, Time 1 respondents were mailed a follow-up survey; 406 returned a completed questionnaire (response rate=39.8%).

METHODS

Surveys containing standardized questionnaires were mailed to participants' home address. Descriptive statistics, correlations, and hierarchical linear regression analyses were conducted using SPSS software.

RESULTS

Overall, new graduate nurses were positive about their experiences and committed to nursing. However, over half of new nurses in the first year of practice reported high levels of emotional exhaustion and many witnessed or experienced incivility (24-42%) at work. Findings from hierarchical linear regression analyses revealed that situational and personal factors explained significant amounts of variance in new graduate nurses' job and career satisfaction and turnover intentions. Cynicism was a significant predictor of all four outcomes one year later, while Psycap predicted job and career satisfaction and career turnover intentions.

CONCLUSIONS

Results provide a look into the worklife experiences of Canadian new graduate nurses over a one-year time period and identify factors that influence their job-related outcomes. These findings show that working conditions for new graduate nurses are generally positive and stable over time, although workplace mistreatment is an issue to be addressed.

Heterosexual female adolescents' decision-making about sexual intercourse and pregnancy in rural Ontario, Canada

INTRODUCTION

Rural female adolescents experience unique circumstances to sexual health care and information as compared to urban adolescents. These circumstances are largely due to their more isolated geographical location and rural sociocultural factors. These circumstances may be contributing factors to an incidence of adolescent pregnancy that is higher in rural areas than in urban cities. Thus, this higher incidence of pregnancy may be due to the ways in which rural adolescents make decisions regarding engagement in sexual intercourse. However, the rural female adolescent sexual decision-making process has rarely, if ever, been studied, and further investigation of this process is necessary. Focusing on rural female adolescents aged 16-19 years is especially significant as this age range is used for reporting most pregnancy and birth statistics in Ontario.

METHODS

Charmaz's guidelines for a constructivist grounded theory methodology were used to gain an in-depth understanding of eight Ontario rural female adolescents' decision-making process regarding sexual intercourse and pregnancy, and how they viewed rural factors and circumstances influencing this process. Research participants were obtained through initial sampling (from criteria developed prior to the study) and theoretical sampling (by collecting data that better inform the categories emerging from the data). Eight participants, aged 16-19 years, were invited to each take part in 1-2-hour individual interviews, and four of these participants were interviewed a second time to verify and elaborate on emerging constructed concepts, conceptual relationships, and the developing process. Data collection and analysis included both field notes and individual interviews in person and over the telephone. Data were analyzed for emerging themes to construct a theory to understand the participants' experiences making sexual decisions in a rural environment.

RESULTS

The adolescent sexual decision-making process, Prioritizing Influences, that emerged from the analysis was a complex and non-linear process that involved prioritizing four influences within the rural context. The influences that participants of this study described as being part of their sexual decision-making process were personal values and circumstances, family values and expectations, friends' influences, and community influences. When influences coincided, they strengthened participants' sexual decisions, whereas when influences opposed each other, participants felt conflicted and prioritized the influence that had the most effect on their personal lives and future goals. Although these influences may be common to all adolescents, they impact the rural female adolescent sexual decision-making process by influencing and being influenced by geographical and sociocultural factors that make up the rural context.

CONCLUSIONS

This study reveals important new and preliminary information about rural female adolescents' sexual decision-making process and factors that affect it. Findings improve understanding of how rural female adolescents make choices regarding sexual intercourse and pregnancy and can be used to guide future research projects that could facilitate effective development of sexual health promotion initiatives, inform rural health policy and practices, and enhance existing sexual education programs in rural communities.

Supporting children with disabilities at school: implications for the advocate role in professional practice and education

PURPOSE

School settings are a common practice context for rehabilitation professionals; health advocacy is a common and challenging practice role for professionals in this context. This study explored how pediatric practitioners advocate for children with disabilities at school. Specifically, we examined everyday advocacy in the context of school-based support for children with disabilities.

METHOD

Our theoretical framework and methodological approach were informed by institutional ethnography, which maps and makes visible hidden social coordinators of work processes with a view to improving processes and outcomes. We included families, educators, and health/rehabilitation practitioners from Ontario. Of the 37 consented informants, 27 were interviewed and 15 observed. Documents and texts were collected from the micro-level (e.g. clinician reports) and the macro-level (e.g. policies).

RESULTS

Pediatric practitioners' advocacy work included two main work processes: spotlighting invisible disabilities and orienteering the special education terrain. Practitioners advocated indirectly, by proxy, with common proxies being documents and parents. Unintended consequences of advocacy by proxy included conflict and inefficiency, which were often unknown to the practitioner.

CONCLUSIONS

The findings of this study provide practice-based knowledge about advocacy for children with disabilities, which may be used to inform further development of competency frameworks and continuing education for pediatric practitioners. The findings also show how everyday practices are influenced by policies and social discourses and how rehabilitation professionals may enact change. Implications for Rehabilitation Rehabilitation professionals frequently perform advocacy work. They may find it beneficial to perform advocacy work that is informed by overarching professional and ethical guidelines, and a nuanced understanding of local processes and structures. Competency frameworks and education for pediatric rehabilitation professionals may be improved by: encouraging professionals to consider how their practices, including their written documents, may affect parental burden, (mis)interpretation by document recipients, and potential unintended consequences. Policies and texts, e.g. privacy legislation and the Diagnostic and Statistical Manual (DSM), influence rehabilitation professionals' actions and interactions when supporting children with disabilities at school. An awareness of the influence of policies and texts may enable practitioners to work more effectively within current systems when supporting individuals with disabilities.

A landscape of hairy and twisted: hunting for new trichome mutants in the Saskatoon Arabidopsis T-DNA population

A total of 88 new Arabidopsis lines with trichome variation were recovered by screening 49,200 single-seed descent T3 lines from the SK activation-tagged population and from a new 20,000-line T-DNA insertion population (called pAG). Trichome variant lines were classified into 12 distinct phenotype categories. Single or multiple T-DNA insertion sites were identified for 89% of these mutant lines. Alleles of the well-known trichome genes TRY, GL2 and TTG1 were recovered with atypical phenotype variation not reported previously. Moreover, atypical gene expression profiles were documented for two additional mutants specifying TRY and GL2 disruptions. In remaining mutants, ten lines were disrupted in genes coding for proteins not implicated in trichome development, five were disrupted in hypothetical proteins and 11 were disrupted in proteins with unknown function. The collection represents new opportunities for the plant biology community to define trichome development more precisely and to refine the function of individual trichome genes.

The influence of empowerment, authentic leadership, and professional practice environments on nurses' perceived interprofessional collaboration

AIM

The aim of this study was to examine the influence of structural empowerment, authentic leadership and professional nursing practice environments on experienced nurses' perceptions of interprofessional collaboration.

BACKGROUND

Enhanced interprofessional collaboration (IPC) is seen as one means of transforming the health-care system and addressing concerns about shortages of health-care workers. Organizational supports and resources are suggested as key to promoting IPC.

METHODS

A predictive non-experimental design was used to test the effects of structural empowerment, authentic leadership and professional nursing practice environments on perceived interprofessional collaboration. A random sample of experienced registered nurses (n = 220) in Ontario, Canada completed a mailed questionnaire. Hierarchical multiple regression analysis was used.

RESULTS

Higher perceived structural empowerment, authentic leadership, and professional practice environments explained 45% of the variance in perceived IPC (Adj. R² = 0.452, F = 59.40, P < 0.001).

CONCLUSIONS

Results suggest that structural empowerment, authentic leadership and a professional nursing practice environment may enhance IPC.

IMPLICATIONS FOR NURSING MANAGEMENT

Nurse leaders who ensure access to resources such as knowledge of IPC, embody authenticity and build trust among nurses, and support the presence of a professional nursing practice environment can contribute to enhanced IPC.

Development and validation of a computer-based algorithm to identify foreign-born patients with HIV infection from the electronic medical record

OBJECTIVE

To develop and validate an efficient and accurate method to identify foreign-born patients from a large patient data registry in order to facilitate population-based health outcomes research.

METHODS

We developed a three-stage algorithm for classifying foreign-born status in HIV-infected patients receiving care in a large US healthcare system (January 1, 2001-March 31, 2012) (n = 9,114). In stage 1, we classified those coded as non-English language speaking as foreign-born. In stage 2, we searched free text electronic medical record (EMR) notes of remaining patients for keywords associated with place of birth and language spoken. Patients without keywords were classified as US-born. In stage 3, we retrieved and reviewed a 50-character text window around the keyword (i.e. token) for the remaining patients. To validate the algorithm, we performed a chart review and asked all HIV physicians (n = 37) to classify their patients (n = 957).We calculated algorithm sensitivity and specificity.

RESULTS

We excluded 160/957 because physicians indicated the patient was not HIV-infected (n = 54), "not my patient" (n = 103), or had unknown place of birth (n = 3), leaving 797 for analysis. In stage 1, providers agreed that 71/95 foreign language speakers were foreign-born. Most disagreements (23/24) involved patients born in Puerto Rico. In stage 2, 49/50 patients without keywords were classified as US-born by chart review. In stage 3, token review correctly classified 55/60 patients (92%), with 93% (CI: 84.4, 100%) sensitivity and 90% (CI: 74.3, 100%) specificity compared with full chart review. After application of the three-stage algorithm, 2,102/9,114 (23%) patients were classified as foreign-born. When compared against physician response, estimated sensitivity of the algorithm was 94% (CI: 90.9, 97.2%) and specificity 92% (CI: 89.7, 94.1%), with 92% correctly classified.

CONCLUSION

A computer-based algorithm classified foreign-born status in a large HIV-infected cohort efficiently and accurately. This approach can be used to improve EMR-based outcomes research.

Primary health care service use among women who have recently left an abusive partner: income and racialization, unmet need, fits of services, and health

Primary health care (PHC) can improve the health of women who have experienced intimate partner violence; yet, access to and fit of PHC services may be shaped by income and racialization. We examined whether income and racialization were associated with differences in PHC service use, unmet needs, fit with needs, and mental and physical health in a sample of 286 women who had separated from an abusive partner. Mothers, unemployed women, and those with lower incomes used more PHC services and reported a poorer fit of services. Poorer fit of services was related to poorer mental and physical health.

Public health human resources: a comparative analysis of policy documents in two Canadian provinces

BACKGROUND

Amidst concerns regarding the capacity of the public health system to respond rapidly and appropriately to threats such as pandemics and terrorism, along with changing population health needs, governments have focused on strengthening public health systems. A key factor in a robust public health system is its workforce. As part of a nationally funded study of public health renewal in Canada, a policy analysis was conducted to compare public health human resources-relevant documents in two Canadian provinces, British Columbia (BC) and Ontario (ON), as they each implement public health renewal activities.

METHODS

A content analysis of policy and planning documents from government and public health-related organizations was conducted by a research team comprised of academics and government decision-makers. Documents published between 2003 and 2011 were accessed (BC = 27; ON = 20); documents were either publicly available or internal to government and excerpted with permission. Documentary texts were deductively coded using a coding template developed by the researchers based on key health human resources concepts derived from two national policy documents.

RESULTS

Documents in both provinces highlighted the importance of public health human resources planning and policies; this was particularly evident in early post-SARS documents. Key thematic areas of public health human resources identified were: education, training, and competencies; capacity; supply; intersectoral collaboration; leadership; public health planning context; and priority populations. Policy documents in both provinces discussed the importance of an educated, competent public health workforce with the appropriate skills and competencies for the effective and efficient delivery of public health services.

CONCLUSION

This policy analysis identified progressive work on public health human resources policy and planning with early documents providing an inventory of issues to be addressed and later documents providing evidence of beginning policy development and implementation. While many similarities exist between the provinces, the context distinctive to each province has influenced and shaped how they have focused their public health human resources policies.

Using an integrated knowledge translation approach to build a public health research agenda

BACKGROUND

Public Health Systems Research is an emerging field of research that is gaining importance in Canada.

METHODS

On October 22 and 23, 2012, public health researchers, practitioners, and policy-makers came together at the Accelerating Public Health Systems Research in Ontario: Building an Agenda think tank to develop a research agenda for the province.

RESULTS

This agenda included the identification of the six top priorities for research in Ontario: public health performance, evidence-based practice, public health organization and structure, public health human resources, public health infrastructure, and partnerships/linkages.

CONCLUSIONS

This paper explores the priorities in detail and hopes to bring more attention to this area of research.

The influence of empowerment and incivility on the mental health of new graduate nurses

AIM

To test a model based on Kanter's theory of structural empowerment, which examines the relationships between new graduate nurses' perceptions of structural empowerment, workplace incivility and mental health symptoms.

BACKGROUND

The initial years of practice can be particularly stressful for new graduate nurses, who may be particularly vulnerable to uncivil behaviour as a result of their status in the work environment. Disempowerment and incivility in the workplace may compound the mental health symptoms experienced by new graduate nurses.

METHOD

A predictive, non-experimental design was used to examine the relationship between structural empowerment, workplace incivility and mental health symptoms in a sample of new graduate nurses working in hospital settings in Ontario (n = 394).

RESULT

High levels of structural empowerment were significantly associated with fewer negative mental health symptoms in new graduates. However, co-worker incivility and supervisor incivility partially mediated the effect of structural empowerment on new graduate nurses' mental health symptoms.

CONCLUSION

The findings suggest that empowering workplaces contribute to lower mental health symptoms in new graduate nurses, an effect that is diminished by incivility.

IMPLICATIONS FOR NURSING MANAGEMENT

Strategies that foster empowering work conditions and reduce uncivil behaviour are needed to promote positive mental health in new graduate nurses.

Linkage to care following community-based mobile HIV testing compared with clinic-based testing in Umlazi Township, Durban, South Africa

OBJECTIVES

The aim of the study was to assess HIV prevalence, disease stage and linkage to HIV care following diagnosis at a mobile HIV testing unit, compared with results for clinic-based testing, in a Durban township.

METHODS

This was a prospective cohort study. We enrolled adults presenting for HIV testing at a community-based mobile testing unit (mobile testers) and at an HIV clinic (clinic testers) serving the same area. Testers diagnosed with HIV infection, regardless of testing site, were offered immediate CD4 testing and instructed to retrieve results at the clinic. We assessed rates of linkage to care, defined as CD4 result retrieval within 90 days of HIV diagnosis and/or completion of antiretroviral therapy (ART) literacy training, for mobile vs. clinic testers.

RESULTS

From July to November 2011, 6957 subjects were HIV tested (4703 mobile and 2254 clinic); 55% were female. Mobile testers had a lower HIV prevalence than clinic testers (10% vs. 36%, respectively), were younger (median 23 vs. 27 years, respectively) and were more likely to live >5 km or >30 min from the clinic (64% vs. 40%, respectively; all P < 0.001). Mobile testers were less likely to undergo CD4 testing (33% vs. 83%, respectively) but more likely to have higher CD4 counts [median (interquartile range) 416 (287-587) cells/μL vs. 285 (136-482) cells/μL, respectively] than clinic testers (both P < 0.001). Of those who tested HIV positive, 10% of mobile testers linked to care, vs. 72% of clinic testers (P < 0.001).

CONCLUSIONS

Mobile HIV testing reaches people who are younger, who are more geographically remote, and who have earlier disease compared with clinic-based testing. Fewer mobile testers underwent CD4 testing and linked to HIV care. Enhancing linkage efforts may improve the impact of mobile testing for those with early HIV disease.

Measurement of electron temperature of imploded capsules at the National Ignition Facility

The electron and ion temperatures of the imploded core plasma are two of the most important metrics of inertial confinement fusion experiments. We have developed a technique for inferring electron temperatures from the contrast of x-ray images observed through a group of x-ray filters. Generally, the plasma electron temperature exhibits spatial and temporal variations, so time-averaged and time-resolved measurements are expected to yield somewhat different results. By analyzing the intensity of images observed with both a time-integrated detector (imaging plates) and a time-resolved detector (gated micro-channel plate), we found the electron temperature observed from x-ray images to be systematically higher than the ion temperature inferred from fusion neutron spectroscopy.
