An empirical application of "broken windows" and related theories in healthcare: examining disorder, patient safety, staff outcomes, and collective efficacy in hospitals

Background

Broken windows theory (BWT) proposes that visible signs of crime, disorder and anti-social behaviour – however minor – lead to further levels of crime, disorder and anti-social behaviour. While we acknowledge divisive and controversial policy developments that were based on BWT, theories of neighbourhood disorder have recently been proposed to have utility in healthcare, emphasising the potential negative effects of disorder on staff and patients, as well as the potential role of collective efficacy in mediating its effects. The aim of this study was to empirically examine the relationship between disorder, collective efficacy and outcome measures in hospital settings. We additionally sought to develop and validate a survey instrument for assessing BWT in hospital settings.

Methods

Cross-sectional survey of clinical and non-clinical staff from four major hospitals in Australia. The survey included the Disorder and Collective Efficacy Survey (DaCEs) (developed for the present study) and outcome measures: job satisfaction, burnout, and patient safety. Construct validity was evaluated by confirmatory factor analysis (CFA) and reliability was assessed by internal consistency. Structural equation modelling (SEM) was used to test a hypothesised model between disorder and patient safety and staff outcomes.

Results

The present study found that both social and physical disorder were positively related to burnout, and negatively related to job satisfaction and patient safety. Further, we found support for the hypothesis that the relationship from social disorder to outcomes (burnout, job satisfaction, patient safety) was mediated by collective efficacy (social cohesion, willingness to intervene).

Conclusions

As one of the first studies to empirically test theories of neighbourhood disorder in healthcare, we found that a positive, orderly, productive culture is likely to lead to wellbeing for staff and the delivery of safer care for patients.

Avoiding unnecessary hospitalisation for patients with chronic conditions: a systematic review of implementation determinants for hospital avoidance programmes

Background

Studies of clinical effectiveness have demonstrated the many benefits of programmes that avoid unnecessary hospitalisations. Therefore, it is imperative to examine the factors influencing implementation of these programmes to ensure these benefits are realised across different healthcare contexts and settings. Numerous factors may act as determinants of implementation success or failure (facilitators and barriers), by either obstructing or enabling changes in healthcare delivery. Understanding the relationships between these determinants is needed to design and tailor strategies that integrate effective programmes into routine practice. Our aims were to describe the implementation determinants for hospital avoidance programmes for people with chronic conditions and the relationships between these determinants.

Methods

An electronic search of four databases was conducted from inception to October 2019, supplemented by snowballing for additional articles. Data were extracted using a structured data extraction tool and risk of bias assessed using the Hawker Tool. Thematic synthesis was undertaken to identify determinants of implementation success or failure for hospital avoidance programmes for people with chronic conditions, which were categorised according to the Consolidated Framework for Implementation Research (CFIR). The relationships between these determinants were also mapped.

Results

The initial search returned 3537 articles after duplicates were removed. After title and abstract screening, 123 articles underwent full-text review. Thirteen articles (14 studies) met the inclusion criteria. Thematic synthesis yielded 23 determinants of implementation across the five CFIR domains. ‘Availability of resources’, ‘compatibility and fit’, and ‘engagement of interprofessional team’ emerged as the most prominent determinants across the included studies. The most interconnected implementation determinants were the ‘compatibility and fit’ of interventions and ‘leadership influence’ factors.

Conclusions

Evidence is emerging for how chronic condition hospital avoidance programmes can be successfully implemented and scaled across different settings and contexts. This review provides a summary of key implementation determinants and their relationships. We propose a hypothesised causal loop diagram to represent the relationship between determinants within a complex adaptive system.

Systems transformation: learning from change in 60 countries

PURPOSE

Much work about health reform and systems improvement in healthcare looks at shortcomings and universal problems facing health systems, but rarely are accomplishments dissected and analyzed internationally. The purpose of this paper is to address this knowledge gap by examining the lessons learned from health system reform and improvement efforts in 60 countries.

DESIGN/METHODOLOGY/APPROACH

In total, 60 low-, middle- and high-income countries provided a case study of successful health reform, which was gathered into a compendium as a recently published book. Here, the extensive source material was re-examined through inductive content analysis to derive broad themes of systems change internationally.

FINDINGS

Nine themes were identified: improving policy, coverage and governance; enhancing the quality of care; keeping patients safe; regulating standards and accreditation; organizing care at the macro-level; organizing care at the meso- and micro-level; developing workforces and resources; harnessing technology and IT; and making collaboratives and partnerships work.

PRACTICAL IMPLICATIONS

These themes provide a model of what constitutes successful systems change across a wide sample of health systems, offering a store of knowledge about how reformers and improvement initiators achieve their goals.

ORIGINALITY/VALUE

Few comparative international studies of health systems include a sufficiently wide selection of low-, middle- and high-income countries in their analysis. This paper provides a more balanced approach to consider where achievements are being made across healthcare, and what we can do to replicate and spread successful examples of systems change internationally.

"Are you ready?" Validation of the Hospital Change Readiness (HCR) Questionnaire

OBJECTIVE

Organisational change in hospitals is a frequent, seemingly inevitable occurrence. A critical precursor to successful organisational change is change readiness. This paper presents the adaptation of a self-report measure of change readiness for hospital staff, examines its reliability and validity, and evaluates the relationship between hospital change readiness (HCR) and staff well-being.

METHODS

The questionnaire was piloted among 153 staff from a large metropolitan, public hospital in Sydney, Australia. The hospital was undergoing a major change involving a multimillion-dollar development project that included a new building and new models of care. Construct validity was evaluated by confirmatory factor analysis (CFA) and reliability was assessed by internal consistency. Differences between professional groups were examined using regression analyses and structural equation modelling (SEM) was used to test the relationship between change readiness and staff well-being (job satisfaction and burnout).

RESULTS

The HCR Questionnaire was found to reflect theoretically derived and empirically observed domains and have high internal reliability. CFA identified that a two-factor structure demonstrated excellent fit. Cronbach's alpha for the two subscales (appropriateness and change efficacy) was 0.85 and 0.75, respectively. No statistically significant differences of HCR were identified between professional groups. SEM revealed that perceiving change as appropriate was significantly positively related to job satisfaction (0.33) and significantly negatively related to burnout (-0.30), and feeling capable in implementing the change was significantly negatively related to burnout (-0.40).

CONCLUSIONS

The HCR Questionnaire provides reliable information on how prepared hospital staff felt for organisational change and showed significant relationships with staff well-being. This questionnaire is validated for the Australian hospital context, particularly in the case of hospital redevelopment. It can be used to help manage times of hospital organisational change with minimal disruption to the quality and safety of patient care.

Exploring interdisciplinary teamwork to support effective ward rounds

PURPOSE

This paper aims to explore if health professionals share understanding of teamwork that supports collaborative ward rounds.

DESIGN/METHODOLOGY/APPROACH

A purpose-designed survey was conducted in two acute medical and two rehabilitation wards from a metropolitan teaching hospital. Medical officers, nurses and allied health professionals participated. To understand characteristics that support collaborative ward rounds, questions developed from literature and industry experience asked: what are the enablers and challenges to teamwork; and what are clinicians' experiences of positive teamwork? Descriptive and thematic analyses were applied to the dimensions of effective teamwork as a framework for deductive coding.

FINDINGS

Seventy-seven clinicians participated (93% response rate). Findings aligned with dimensions of teamwork framework. There was no meaningful difference between clinicians or specialty. Enablers to teamwork were: effective communication, shared understanding of patient goals, and colleague's roles. Challenges were ineffective communication, individual personalities, lack of understanding about roles and responsibilities, and organisational structure. Additional challenges included: time; uncoordinated treatment planning; and leadership. Positive teamwork was influenced by leadership and team dynamics.

PRACTICAL IMPLICATIONS

Ward rounds benefit from a foundation of collaborative teamwork. Different dimensions of teamwork present during ward rounds support clinicians' shared understanding of roles, expectations and communication.

ORIGINALITY/VALUE

Rounds such as structured rounding, aim to improve teamwork. Inverting this concept to first develop effective collaboration will support team adaptability and resilience. This enables teams to transition between the multiple rounding processes undertaken in a single ward. The emphasis becomes high-quality teamwork rather than a single rounding process.

Development of an implementation and evaluation strategy for the Australian 'Zero Childhood Cancer' (Zero) Program: a study protocol

INTRODUCTION

Effective implementation of a research Program requires an actionable plan to guide execution. To assess the actionability and success of that plan, both scientific and implementation elements must be taken into account. The aim of this study is to assess the 'Zero Childhood Cancer Personalised Medicine Program' (the Zero Program), an Australian first-ever and most comprehensive personalised medicine programme for children with high-risk or relapsed cancer, in terms of its structure, process and implementational effect.

METHODS AND ANALYSIS

We will assess Program delivery mechanisms. The development of the implementation and evaluation strategy will concentrate on the work of the Zero Program as a complex whole. This includes the structure of collaborative links across stakeholder groups involved in Program development and delivery, changes to collaborative relationships over time and the impact of group working on Program outcomes. We are applying a mixed-methods design including: a rapid ethnography (observations of stakeholder interactions and informal conversations), Program professionals' completion of a rapid health implementation proforma and a social network analysis. Formative evaluations of the implementation science effects, applying feedback techniques, for example, Formative Evaluation Feedback Loops and the Zero Program professionals' feedback, will determine where Program tailoring may be needed. A repeat of the social network analysis downstream will examine network changes over time, followed by an expert panel using the expert recommendations for implementing change to assess the integration of implementation strategies into the Program structure. A summative evaluation of the Program will bring the research elements together, leading to comprehensive data triangulation and determining the sustainability and implementational effects of Program delivery.

ETHICS AND DISSEMINATION

Ethical approval for this study has been granted by Hunter New England Research Ethics Committee, New South Wales, Australia (approval ref: 2019/ETH12025). Knowledge translation will be achieved through publications, reports and conference presentations to healthcare professionals, patients, families and researchers.

Clinicians' perceptions of rounding processes and effectiveness of clinical communication

RATIONALE, AIMS, AND OBJECTIVES

Ward rounds present opportunities for medical officers, nurses, allied health clinicians, and patients to interact and plan patient care. A recent literature review found eight types of rounding processes. Different purposes, varying levels of representation from clinical professions, and understanding of each others' roles revealed a complex activity. A shared understanding of rounding processes facilitates positive teamwork and improves patient care. We examined how clinicians perceive the nature of rounding processes they undertake within their practice, multidisciplinary team attendance at rounds, and the effectiveness of team communication.

METHODS

We surveyed frontline professionals in two acute care and two rehabilitation wards from a metropolitan teaching hospital. There were 77 participants representing medical officers, nurses, and allied health clinicians. Participants selected the type of rounding processes undertaken on their ward from a list of six defined types, then answered questions about who participated in the rounds and their perceptions of the effectiveness of multidisciplinary communication. Survey findings were analysed using descriptive statistics and comparison.

RESULTS

Overall, professionals were inconsistent in the identification of number and types of rounds. Participants nominated processes more consistently within individual clinical disciplines than by clinical speciality. Medical officers identified rounds most consistently, while some nurses were unable to identify any rounding processes undertaken. The perceptions clinicians had of their own attendance at rounds differed from that of their colleagues. Despite variation in perceptions about rounds, professionals reported effective multidisciplinary communication patterns overall.

CONCLUSION

Rounds are a common yet complex activity. Rounds are revealed to be a taken-for-granted organizational activity with diversity in function, attendance, and participation, yet rounding processes are perceived and experienced differently between health professions. These differences impact on multidisciplinary attendance at rounds amongst peers. Making and communicating explicit round expectations and roles for clinicians supports coordinated teamwork and care planning.

The rise of rapid implementation: a worked example of solving an existing problem with a new method by combining concept analysis with a systematic integrative review

BACKGROUND

The concept of rapid implementation has emerged in the literature recently, but without a precise definition. Further exploration is required to distinguish the concept's unique meanings and significance from the perspective of implementation science. The study clarifies the concept of rapid implementation and identifies its attributes, antecedents, and consequences. We present a theoretical definition of rapid implementation to clarify its unique meaning and characteristics.

METHODS

Rodgers evolutionary concept analysis method, combined with a systematic integrative review, were used to clarify the concept of rapid implementation. A comprehensive search of four databases, including EMBASE, MEDLINE, SCOPUS, and WEB OF SCIENCE was conducted, as well as relevant journals and reference lists of retrieved studies. After searching databases, 2442 papers were identified from 1963 to 2019; 24 articles were found to fit the inclusion criteria to capture data on rapid implementation from across healthcare settings in four countries. Data analysis was carried out using descriptive thematic analysis.

RESULTS

The results locate the introduction of rapid implementation, informed by implementation science. Guidance for further conceptualisation to bridge the gap between research and practice and redefine rigour, adapting methods used (current approaches, procedures and frameworks), and challenging clinical trial design (efficacy-effectiveness-implementation pipeline) is provided.

CONCLUSIONS

It is possible that we are on the cusp of a paradigm shift within implementation brought about by the need for faster results into practice and policy. Researchers can benefit from a deeper understanding of the rapid implementation concept to guide future implementation of rapid actionable results in clinical practice.

Evaluation of a hospital-based integrated model of eye care for diabetic retinopathy assessment: a multimethod study

OBJECTIVES

Diabetic eye disease is a leading cause of blindness but can be mitigated by regular eye assessment. A framework of issues, developed from the literature of barriers to eye assessment, was used to structure an examination of perceptions of a new model of care for diabetic retinopathy from the perspective of staff using the model, and health professionals referring patients to the new service.

DESIGN

Multimethod: interviews and focus groups, and a separate survey.

SETTING

A new clinic based on an integrated model of care was established at a hospital in outer metropolitan Sydney, Australia in 2017. Funded jointly by Centre for Eye Health (CFEH) and the hospital, the clinic was equipped and staffed by optometrists who work alongside the ophthalmologists in the existing hospital eye clinic.

PARTICIPANTS

Five (of seven) hospital staff working in the clinic (ophthalmologists and administrative officers) or referring to it from other departments (endocrinologists); nine optometrists from CFEH who developed or worked in the clinic; 10 community-based optometrists as potential referrers.

RESULTS

The new clinic was considered to have addressed known barriers to eye assessment, including access, assistance for patients unable/unwilling to organise eye checks and efficient management of human resources. The clinic optimised known drivers of this model of care: providing clear scope of practice and protocols for shared care between optometrists and ophthalmologists, good communication between referrers and eye professionals and a collegial approach promoting interprofessional trust. Remaining areas of concern were few referrals from general practitioners, fewer referrals from hospital endocrinologists than expected and issues with stretched administrative capacity. There were also perceived mismatches between the priorities of hospital management and aims of the clinic.

CONCLUSIONS

The new model was considered to have addressed many of the barriers to assessment. While there remain issues with the model, there were also unexpected benefits.

Implementation of e-mental health for depression and anxiety: A critical scoping review

The aim of this review was to scope the growth and development of implementation research of e-mental healthcare programs for anxiety and depression, the research and evaluation tools used, and the specific implementation processes and outcomes examined. A search of four electronic databases (MEDLINE, EMBASE, PsycINFO, and CINAHL) was conducted from January 2000 to January 2019. Of 33 studies identified, most (n = 28) were published in the last five years. Only 10 used an implementation framework to guide implementation or evaluation. Most studies reported on acceptability (n = 28), appropriateness (n = 23), and feasibility (n = 17). Less commonly reported implementation outcomes were fidelity (n = 10) and adoption (n = 7); with penetration (n = 4), sustainability (n = 3), and implementation cost (n = 2) being studied rarely. Of the 21 studies that used surveys to study implementation outcomes, less than half used a previously published survey (n = 9). More rigorous implementation studies, underpinned by strong theory and real-world understanding, are urgently needed.

Guideline adherence in the management of head injury in Australian children: A population-based sample survey

BACKGROUND

Head injuries in children are a common and potentially devastating presentation. The CareTrack Kids (CTK) study assessed care of Australian children aged 0-15 years, in 2012 and 2013, to evaluate the proportion in line with guideline-based indicators for 17 common conditions. Overall adherence to guideline-based recommended practice occurred 59.8% of care encounters (95% CI: 57.5-62.0), and 78.3% (95% CI: 75.1-81.2) for head injury. This paper presents results for head injury, at indicator level.

METHODS

A modified version of the RAND-UCLA method of indicator development was used. Indicators, measurable components of a standard or guideline, were developed from international and national guidelines relating to head injury in children and were ratified by clinical experts using a Delphi process. Paediatric nurses extracted data from medical records from general practitioners (GPs), emergency departments (EDs) and inpatient wards in Queensland, New South Wales and South Australia, for children under 15 years receiving care in 2012-13. Our purpose was to estimate the percentage adherent for each indicator.

RESULTS

The medical records of 629 children with head injury were examined. Fifty-one percent of children were under 5 years old, with more males (61%) than females. Thirty-eight indicators were assessed. Avoidance of nasotracheal airways (100%; 95% CI: 99.4-100) or nasogastric tubes (99.7%; 95% CI: 98.5-100) for children with a head injury had the highest adherence. Indicators relating to primary and secondary assessment of head injuries were mostly adhered to. However, adherence to other indicators was poor (e.g., documentation of the past history of children (e.g., presence or absence of seizures) before the injury; 29.9% (95% CI: 24.5-35.7)), and for others was difficult to estimate with confidence due to small sample sizes (e.g., Children with a head injury who were intubated had PaO2 above 80mm Hg; 56.0% (95% CI: 28.6-80.9)). Indicators guiding clinical decision making regarding the need for CT scan had insufficient data to justify reporting.

CONCLUSION

This study highlights that management of head injury in children mostly follows guidelines, but also flags some specific areas of inconsistency. Individual sites are encouraged to use these results to guide investigation of local practices and inform quality improvement endeavours.

Clinical genomic testing: what matters to key stakeholders?

Beyond a narrow focus on cost and outcomes, robust evidence of what is valued in genomic medicine is scarce. We gathered views on value from key stakeholders (clinical genomic staff, operational genomic staff and community representatives) in relation to three testing contexts (General Healthcare, Acute Care and Neurodevelopmental Conditions). We conducted an iterative focus group in three stages over a week using a multiphase mixed methods study, i.e. quantitative ratings and qualitative discussion. For each testing context, the characteristics of genomic testing were generated and ranked by the group using a co-productive approach. Up to 17 characteristics were identified in one scenario with several characteristics featuring in all three testing contexts. The likelihood of getting an answer was consistently reported as most highly valued, followed by the potential for the test to impact on clinical management (or wellbeing/health for Neurodevelopmental Conditions). Risk of discrimination did not feature highly across the different settings (and not at all in Acute Care). While cost was an issue in the general health setting, it was one of the least-valued characteristics in the other two testing contexts. In conclusion, co-producing an understanding of what is valued in different testing contexts, and identifying the areas of differences or commonalities, is important to maximise value provision and inform future policy to ensure that clinical genomic services meet the needs of the community and service providers.

Interprofessional collaboration in hospitals: a critical, broad-based review of the literature

Interprofessional collaboration (IPC) is a common term applied in the healthcare literature, with suggestions it contributes to improved quality and safety of patient care across the globe. Despite worldwide implementation of models of IPC, past systematic or meta-reviews on this topic have concluded that the evidence is mixed. However, these reviews are yet to adequately consider the qualitative and mixed-methods literature on this topic. In this critical review, we synthesize the outcomes and key findings of IPC in hospitals, taking a broader approach by including diverse study designs. A total of 4,776 abstracts were screened from three major databases (Medline, CINAHL, Embase). Thirty-four studies fulfilled inclusion criteria. Although outcomes and key findings (e.g., staff turnover, error rates) were mostly positive, there were inconsistencies in the results. The included studies reflected a variety of study designs and different methodological approaches. Overall, our review revealed moderate evidence that IPC can positively influence patient, staff and organizational factors in hospitals, and that inconsistent findings may be due to variation in context (e.g., the cohort of patients). Recommendations from the review are to incorporate qualitative- and mixed-methods approaches to studying IPC in healthcare and tailor evaluations of IPC outcomes specific to the context.

How Do Interprofessional Healthcare Teams Perceive the Benefits and Challenges of Interdisciplinary Ward Rounds

Purpose

Interdisciplinary bedside ward rounds have the capacity to facilitate coordinated interprofessional patient care. To be an effective means of care coordination, clinicians need an explicit understanding of how these rounds contribute to patient care. By identifying benefits and challenges to the effective use of interdisciplinary ward rounds, clinicians create an opportunity to improve interprofessional teamwork, care planning, and coordination of patient care.

Methods

A survey was conducted with frontline professionals in two acute care and two rehabilitation wards from a metropolitan teaching hospital. There were 77 participants, representing medical officers, nurses, and allied health clinicians. Questions examined the perceived benefits and challenges of conducting interdisciplinary ward rounds in their units. Survey findings were coded for meaning and then grouped into themes.

Results

Benefits revealed a desired care delivery model challenged by the complexities of organizational and professional cultures. The themes of “being on the same page”, “focusing on patients”, and “holistic care planning” underpinned the ideas of collaboration and improved patient-centred care, that is, benefits to patients. Challenges centred on health professionals' time constraints and the coordination of teams to enable participation in rounds. The themes were more distinct, logistical barriers of “time”, “workforce”, and “care planning”.

Conclusion

Overall, clinicians recognise there are greater benefits to IBRs and have a willingness to participate. However, careful consideration is required to introduce and continually achieve the best from IBR as they require changes in organizational context and culture.

Organisational change in hospitals: a qualitative case-study of staff perspectives

Background

Organisational change in health systems is common. Success is often tied to the actors involved, including their awareness of the change, personal engagement and ownership of it. In many health systems, one of the most common changes we are witnessing is the redevelopment of long-standing hospitals. However, we know little about how hospital staff understand and experience such potentially far-reaching organisational change. The purpose of this study is to explore the understanding and experiences of hospital staff in the early stages of organisational change, using a hospital redevelopment in Sydney, Australia as a case study.

Methods

Semi-structured interviews were conducted with 46 clinical and non-clinical staff working at a large metropolitan hospital. Hospital staff were moving into a new building, not moving, or had moved into a different building two years prior. Questions asked staff about their level of awareness of the upcoming redevelopment and their experiences in the early stage of this change. Qualitative data were analysed using thematic analysis.

Results

Some staff expressed apprehension and held negative expectations regarding the organisational change. Concerns included inadequate staffing and potential for collaboration breakdown due to new layout of workspaces. These fears were compounded by current experiences of feeling uninformed about the change, as well as feelings of being fatigued and under-staffed in the constantly changing hospital environment. Nevertheless, balancing this, many staff reported positive expectations regarding the benefits to patients of the change and the potential for staff to adapt in the face of this change.

Conclusions

The results of this study suggest that it is important to understand prospectively how actors involved make sense of organisational change, in order to potentially assuage concerns and alleviate negative expectations. Throughout the processes of organisational change, such as a hospital redevelopment, staff need to be engaged, adequately informed, trained, and to feel supported by management. The use of champions of varying professions and lead departments, may be useful to address concerns, adequately inform, and promote a sense of engagement among staff.

Assessing the quality of care for paediatric depression and anxiety in Australia: A population-based sample survey

OBJECTIVE

We examine the prevalence of quality care (as measured by adherence to recommendations in clinical practice guidelines) for Australian paediatric patients (⩽15 years) with depression and/or anxiety, using data from the CareTrack Kids study; a population-based study of the quality of healthcare practice in inpatient and ambulatory healthcare settings.

METHODS

A multistage stratified sample identified records of 6689 children. Of these, 156 records were identified for depression and 356 for anxiety. These were assessed for adherence to 15 depression and 13 anxiety indicators, respectively, using a review of medical records.

RESULTS

Adherence to assessment and management guidelines was low for both conditions: assessment bundle (depression = 33%, 95% confidence interval = [20, 48]; anxiety = 54%, 95% confidence interval = [43, 64] and depression management bundle = 35%, 95% confidence interval = [15, 60]). Across both conditions, the highest adherence was recorded for indicators that addressed prescription of medications (e.g. venlafaxine, 100%; benzodiazepines, 100%; selective serotonin reuptake inhibitor, 94% and antidepressants, 91%), while compliance was the lowest for ensuring children with depression had an emergency safety plan (44%), informing parents of the risks and benefits of prescribed anxiety medication (51%) and assessment for other causes (59% for depression; 68% for anxiety).

CONCLUSION

These findings suggest that strategies are needed to improve guideline adherence for mental health disorders in children and adolescents, particularly among general practitioners. Learning from these indicators could inform clinical prompts in electronic medical records, as well as links to additional information, to assist in decision-making and streamline work practices.

The Quality of Care for Australian Children with Autism Spectrum Disorders

Knowledge about the quality of care delivered to children with autism spectrum disorders (ASD) in relation to that recommended by clinical practice guidelines (CPGs) is limited. ASD care quality indicators were developed from CPGs and validated by experts, then used to assess the quality of care delivered by general practitioners (GPs) and pediatricians in Australia. Data were retrospectively collected from the medical records of 228 children (≤ 15 years) with ASD for 2012-2013. Overall quality of care was high, but with considerable variation among indicators, and between GPs and pediatricians-e.g., GPs were less likely to complete the assessment care bundle (61%; 95% CI 21-92). Findings highlight potential areas for improvement in the need for standardized criteria for diagnosis.

Exploring the ripple effects of an Australian hospital redevelopment: a protocol for a longitudinal, mixed-methods study

INTRODUCTION

Hospital redevelopment projects typically intend to improve hospital functioning and modernise the delivery of care. There is research support for the proposition that redevelopment along evidence-based design principles can lead to improved quality and safety. However, it is not clear how redevelopment influences the wider context of the hospital and its functioning. That is, beyond a limited examination of intended outcomes (eg, improved patient satisfaction), are there additional consequences (positive, negative or unintended) occurring within the hospital after the physical environment is changed? Is new always better? The primary purpose of this study is to explore the ripple effects of how hospital redevelopment may influence the organisation, staff and patients in both intended and unintended ways.

METHODS AND ANALYSIS

We propose to conduct a longitudinal, mixed-methods, case study of a large metropolitan hospital in Australia. The study design consists of a series of measurements over time that are interrupted by the natural intervention of a hospital redevelopment. How hospital redevelopment influences the wider context of the hospital will be assessed in six domains: expectations and reflections of hospital redevelopment, organisational culture, staff interactions, staff well-being, efficiency of care delivery and patient experience. Methods of data collection include a hospital-wide staff survey, semistructured interviews, a network survey, a patient experience survey, analysis of routinely collected hospital data and observations. In addition to a hospital-level analysis, a total of four wards will be examined in-depth, with two acting as controls. Data will be analysed using thematic, statistical and network analyses, respectively, for the qualitative, quantitative and relational data.

ETHICS AND DISSEMINATION

The study has been reviewed and approved by the relevant Ethics Committee in New South Wales, Australia. The results will be actively disseminated through peer-reviewed journals, conference presentations and in report format to the stakeholders.

The time has come: Embedded implementation research for health care improvement

RATIONALE, AIMS, AND OBJECTIVES

The field of implementation science has developed in response to slow and inconsistent translation of evidence into practice. Despite utilizing increasingly sophisticated approaches to implementation, including applying a complexity science lens and conducting realist evaluations, challenges remain to getting the kinds of outcomes hoped for by implementation efforts. These include gaining access and buy-in from those implementing the change and accounting for the influence of local context. One emerging approach to address these challenges is embedded implementation research-a collaborative, adaptive approach to improvement. It involves researchers and implementers working together in situ from the outset of, and throughout, an implementation project. Both groups can benefit from the collaboration: it increases the rigor of evaluation, provides opportunities to improve the intervention through direct feedback, and promotes better on-the-ground understanding of the change process. We aimed to examine the potential benefits, and some of the challenges, of increased embeddedness.

METHOD

We performed a multi-case analysis of implementation research projects that varied by degree of embeddedness.

RESULTS

Embedded implementation research may offer a range of advantages over dichotomized research-practice designs, including better understanding of local context and direct feedback to improve the implementation along the way. We present a model that spans four approaches: dichotomized research-practice, collaborative linking-up, partially-embedded, and deep immersion.

CONCLUSION

Embedded implementation research approaches hold promise in comparison to traditional dichotomized-research practice designs, where the research is external to the implementation and conducts a summative evaluation. We are only beginning to understand how such partnerships operate in practice and what makes them successful. Our analysis suggests the time has come to consider such approaches.

Assessing the appropriateness of the management of upper respiratory tract infection in Australian children: a population-based sample survey

OBJECTIVE

To assess the proportion of Australian children aged 0-15 years that received care in line with clinical practice guidelines (CPGs) for upper respiratory tract infections (URTIs).

DESIGN

Retrospective medical record review using a multistage sampling strategy.

SETTING

General practices, hospital emergency departments and hospital inpatient service providers in three Australian states.

PARTICIPANTS

Children aged up to 15 years who received care for URTI in 2012 and 2013.

PRIMARY AND SECONDARY OUTCOME MEASURES

The primary assessment was estimated adherence with 14 indicators of appropriate care as documented in medical records. Indicators were extracted from national and international CPGs and ratified by experts. Secondary assessment was adherence to two bundles of indicators (diagnostic symptoms and medical history taking), where all indicators must be adherent for the bundle to be scored as adherent.

RESULTS

There were 1653 children with one or more assessments of URTI care to CPG adherence. Over half of the children were under 3 years of age, with roughly equal numbers of males and females. Three indicators had fewer than 25 visits so were not reported. Overall adherence ranged from 0.5% for 'documented advice around antibiotics' to 88.3% for 'documentation of medical history'. Adherence with Bundle A (documentation of all three definitive symptoms) was 43.1% (95% CI 32.8% to 54.0%) and Bundle B (documentation of all four indicators of medical history) was 30.2% (95% CI 20.9% to 40.9%).

CONCLUSIONS

URTIs in children are common, usually self-limiting, conditions that are allocated considerable resources. The results suggest that there may be a need for more thorough holistic assessment of the patient and improved documentation. Since inappropriate prescription of antibiotics for URTIs is still a known problem in Australia, there is a need for consistent, clear communication around antibiotics' lack of impact on symptoms and a high association with undesirable side effects.

A revised model of uncertainty in complex healthcare settings: A scoping review

BACKGROUND

Uncertainty is a ubiquitous and dynamic presence throughout healthcare systems and encounters, affecting the quality and safety of care. Although previous research has attempted to categorize varieties of uncertainty, it is not clear if these classifications are applicable across various healthcare settings.

OBJECTIVE

The purpose of this review was to examine the applicability of the issues of uncertainty delineated in an established taxonomy across diverse healthcare domains, professions, and countries and to consider the complexity of these issues.

METHODS

Drawing on empirical research from three databases, we conducted a scoping review of the literature to identify types of uncertainty experienced by healthcare professionals. A framework synthesis design was employed to review and synthesize the literature across multiple healthcare settings.

RESULTS

The search identified 2285 articles, of which 94 met the inclusion criteria. Findings from included studies suggested professional uncertainty in healthcare is complex and pervasive. On the basis of our inability to categorize some studies in the issues of uncertainty outlined in the existing taxonomy, we proposed a revised model of uncertainty for healthcare professionals.

CONCLUSIONS

The revised model of uncertainty, the model of uncertainty in complex healthcare settings (MUCH-S), is applicable to various healthcare ecosystems and proposes a reflexive archetype that recognizes different issues of uncertainty while establishing that these are often interrelated in healthcare systems. This review offers healthcare professionals greater levels of understanding of this complex phenomenon and may support more informed and reflective decision-making, assisting them to better navigate uncertainties experienced in healthcare workplaces.

Comprehensive Researcher Achievement Model (CRAM): a framework for measuring researcher achievement, impact and influence derived from a systematic literature review of metrics and models

OBJECTIVES

Effective researcher assessment is key to decisions about funding allocations, promotion and tenure. We aimed to identify what is known about methods for assessing researcher achievements, leading to a new composite assessment model.

DESIGN

We systematically reviewed the literature via the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols framework.

DATA SOURCES

All Web of Science databases (including Core Collection, MEDLINE and BIOSIS Citation Index) to the end of 2017. ELIGIBILITY CRITERIA: (1) English language, (2) published in the last 10 years (2007-2017), (3) full text was available and (4) the article discussed an approach to the assessment of an individual researcher's achievements.

DATA EXTRACTION AND SYNTHESIS

Articles were allocated among four pairs of reviewers for screening, with each pair randomly assigned 5% of their allocation to review concurrently against inclusion criteria. Inter-rater reliability was assessed using Cohen's Kappa (ĸ). The ĸ statistic showed agreement ranging from moderate to almost perfect (0.4848-0.9039). Following screening, selected articles underwent full-text review and bias was assessed.

RESULTS

Four hundred and seventy-eight articles were included in the final review. Established approaches developed prior to our inclusion period (eg, citations and outputs, h-index and journal impact factor) remained dominant in the literature and in practice. New bibliometric methods and models emerged in the last 10 years including: measures based on PageRank algorithms or 'altmetric' data, methods to apply peer judgement and techniques to assign values to publication quantity and quality. Each assessment method tended to prioritise certain aspects of achievement over others.

CONCLUSIONS

All metrics and models focus on an element or elements at the expense of others. A new composite design, the Comprehensive Researcher Achievement Model (CRAM), is presented, which supersedes past anachronistic models. The CRAM is modifiable to a range of applications.

The influence of complexity: a bibliometric analysis of complexity science in healthcare

OBJECTIVES

To analyse trends in the academic literature applying complexity science to healthcare, focusing specifically on bibliometric characteristics and indicators of influence.

DESIGN

This study reports a bibliometric analysis via a systematic search of the academic literature applying complexity science to healthcare.

METHOD

A search of four academic databases was performed on 19 April 2018. Article details were downloaded and screened against inclusion criteria (peer-reviewed journal articles applying complexity science to healthcare). Publication and content data were then collected from included articles, with analysis focusing on trends over time in the types and topics of articles, and where they are published. We also analysed the influence of this body of work through citation and network analyses.

RESULTS

Articles on complexity science in healthcare were published in 268 journals, though a much smaller subset was responsible for a substantial proportion of this literature. USA contributed the largest number of articles, followed by the UK, Canada and Australia. Over time, the number of empirical and review articles increased, relative to non-empirical contributions. However, in general, non-empirical literature was more influential, with a series of introductory conceptual papers being the most influential based on both overall citations and their use as index references within a citation network. The most common topics of focus were health systems and organisations generally, and education, with recent uptake in research, policy, and change and improvement.

CONCLUSIONS

This study identified changes in the types of articles on complexity science in healthcare published over time, and their content. There was evidence to suggest a shift from conceptual work to the application of concrete improvement strategies and increasingly in-depth examination of complex healthcare systems. We also identified variation in the influence of this literature at article level, and to a lesser extent by topic of focus.

Process evaluation of a behaviour change approach to improving clinical practice for detecting hereditary cancer

BACKGROUND

This retrospective process evaluation reports on the application of a 1-year implementation program to increase identification and management of patients at high risk of a hereditary cancer syndrome. The project used the Theoretical Domains Framework Implementation (TDFI) approach, a promising implementation methodology, used successfully in the United Kingdom to address patient safety issues. This Australian project run at two large public hospitals aimed to increase referrals of patients flagged as being at risk of Lynch syndrome on the basis of a screening test to genetic services. At the end of the project, the pathologists' processes had changed, but the referral rate remained inconsistent and low.

METHODS

Semi-structured interviews explored participants' perceptions of the TDFI approach and Health services researchers wrote structured reflections. Interview transcripts and reflections were coded initially against implementation outcomes for the various TDFI approach activities: acceptability, appropriateness, feasibility, value for time cost, and adoption. On a second pass, themes were coded around challenges to the approach.

RESULTS

Interviews were held with nine key project participants including pathologists, oncologists, surgeons, genetic counsellors and an administrative officer. Two health services researchers wrote structured reflections. The first of two major themes was 'Theory-related challenges', with subthemes of accessibility of theory underpinning the TDFI, commitment to that theory-based approach, and the problem of complexity. The second theme was 'Practical challenges' with subthemes of stakeholder management, navigating the system, and perceptions of the problem. Health services researchers reflected on the benefits of bridging professional divides and facilitating collective learning and problem solving, but noted frustrations around clinicians' time constraints that led to sparse interactions with the team, and lack of authority to effect change themselves.

CONCLUSIONS

Mixed success of adoption as an outcome was attributed to the complexity and highly nuanced nature of the setting. This made identifying the target behaviour, a key step in the TDFI approach, challenging. Introduced changes in the screening process led to new, unexpected issues yet to be addressed. Strategies to address challenges are presented, including using an internal facilitator with a focus on applying a theory-based implementation approach.

A transformative translational change programme to introduce genomics into healthcare: a complexity and implementation science study protocol

INTRODUCTION

Translating scientific advances in genomic medicine into evidence-based clinical practice is challenging. Studying the natural translation of genomics into 'early-adopting' health system sectors is essential. We will (a) examine 29 health systems (Australian and Melbourne Genomics Health Alliance flagships) integrating genomics into practice and (b) combine this learning to co-design and test an evidence-based generalisable toolkit for translating genomics into healthcare.

METHODS AND ANALYSIS

Twenty-nine flagships integrating genomics into clinical settings are studied as complex adaptive systems to understand emergent and self-organising behaviours among inter-related actors and processes. The Effectiveness-Implementation Hybrid approach is applied to gather information on the delivery and potential for real-world implementation. Stages '1' and '2a' (representing hybrid model 1) are the focus of this protocol. The Translation Science to Population Impact (TSci Impact) framework is used to study policy decisions and service provision, and the Theoretical Domains Framework (TDF) is used to understand individual level behavioural change; both frameworks are applied across stages 1 and 2a. Stage 1 synthesises interview data from 32 participants involved in developing the genomics clinical practice systems and approaches across five 'demonstration-phase' (early adopter) flagships. In stage 2a, stakeholders are providing quantitative and qualitative data on process mapping, clinical audits, uptake and sustainability (TSci Impact), and psychosocial and environmental determinants of change (TDF). Findings will be synthesised before codesigning an intervention toolkit to facilitate implementation of genomic testing. Study methods to simultaneously test the comparative effectiveness of genomic testing and the implementation toolkit (stage 2b), and the refined implementation toolkit while simply observing the genomics intervention (stage 3) are summarised.

ETHICS AND DISSEMINATION

Ethical approval has been granted. The results will be disseminated in academic forums and used to refine interventions to translate genomics evidence into healthcare. Non-traditional academic dissemination methods (eg, change in guidelines or government policy) will also be employed.

Building a learning community of Australian clinical genomics: a social network study of the Australian Genomic Health Alliance

BACKGROUND

Adopting clinical genomics represents a major systems-level intervention requiring diverse expertise and collective learning. The Australian Genomic Health Alliance (Australian Genomics) is strategically linking members and partner organisations to lead the integration of genomic medicine into healthcare across Australia. This study aimed to map and analyse interconnections between members-a key feature of complexity-to capture the collaborations among the genomic community, document learning, assess Australian Genomics' influence and identify key players.

METHODS

An online, whole network study collected relational data from members asking them about two time points: baseline, before Australian Genomics started operation in 2016 and current in 2018. Likert style questions assessed the influence of various sources of knowledge on the respondents' genomic practice. A secure link to the online questionnaire was distributed to all members of Australian Genomics during May 2018. Social network data was analysed and visually constructed using Gephi 0.9.2 software, and Likert questions were analysed using chi-squared computations in SPSS. The project was given ethical approval.

RESULTS

Response rate was 57.81% (222/384). The genomic learning community within Australian Genomics was constructed from the responses of participants. There was a growth in ties from pre-2016 (2925 ties) to 2018 (6381 ties) and an increase in density (0.020 to 0.043) suggesting the strong influence of Australian Genomics in creating this community. Respondents nominated 355 collaborative partners from 24 different countries outside of Australia and 328 partners from within Australia but outside the alliance. Key players were the Australian Genomics Manager, two clinical geneticists and four Operational staff members. Most influential sources of learning were hands on learning, shared decision making, journal articles and conference presentations in contrast to formal courses.

CONCLUSIONS

The successful implementation of clinical genomics requires the engagement of multidisciplinary teams across a range of conditions and expertise. Australian Genomics is shown to be facilitating this collaborative process by strategically building a genomic learning community. We demonstrate the importance of social processes in building complex networks as respondents name "hands on learning" and "making group decisions" the most potent influences of their genomic practice. This has implications for genomic implementation, education and work force strategies.

What do patients really want? An in-depth examination of patient experience in four Australian hospitals

BACKGROUND

Patient satisfaction is an important outcome measure guiding quality improvement in the healthcare setting while the patient-centred care movement places increasing importance on patient engagement in clinical decision-making. However, the concept of patient satisfaction is not clearly defined, and beliefs of patients are not always evident in health surveys. Researchers rarely follow up on surveys to explore patient views and what they mean in greater depth. This study set out to examine perceptions of hospital care, through in-depth, qualitative data capture and as a result, to gather rich, patient-driven information on user experience and satisfaction in the Australian healthcare setting; and identify influencing factors.

METHODS

Focus groups were undertaken in four St Vincent's Health Australia (SVHA) hospitals in 2017 where participants discussed responses to eight questions from the Press Ganey Patient Experience Survey. Thirty people who were inpatients at SVHA.

RESULTS

Good communication and high-quality information at arrival and discharge were found to be important to patients. Communication breakdown was also evident, further exacerbated by a range of environmental factors such as sharing a room with others. Overall, patients' felt that while their spiritual needs were well-supported by the hospital staff at all SVHA hospitals, it was the clinical teams prioritised their emotional needs. Good communication and environments can improve patient experience and follow-up at home is vital.

CONCLUSIONS

Patient-centred care needs careful planning with patients involved at entry and exit from hospital. Focused communication, environmental changes, attending to complaints, and clearer discharge strategies are recommended.

Combined Search for a Lorentz-Violating Force in Short-Range Gravity Varying as the Inverse Sixth Power of Distance

Precision measurements of the inverse-square law via experiments on short-range gravity provide sensitive tests of Lorentz symmetry. A combined analysis of data from experiments at the Huazhong University of Science and Technology and Indiana University sets simultaneous limits on all 22 coefficients for Lorentz violation correcting the Newton force law as the inverse sixth power of distance. Results are consistent with no effect at the level of 10^{-12}  m^{4}.

Patients, health professionals, and the health system: influencers on patients' participation in ward rounds

BACKGROUND

The ward round is an opportunity to plan and deliver patient-centered care. Benefits include an effective and safer clinician-patient relationship, patient empowerment, reduced anxiety and increased trust in the health care system. Factors contributing to patient involvement in ward rounds is shaped by their preferences, ability, and opportunity.

AIM

To investigate ward rounds and the patient experience with them, the relationship between the patient and clinicians, and how rounds facilitate collaboration between them.

PATIENTS AND METHODS

A multimethod study was conducted in a single Australian facility in acute medicine and rehabilitation specialties. An observational study of ward rounds in each setting was conducted with 14 patients, aged between 55 and 89 years followed by semi-structured interviews conducted with the patients observed. Descriptive and thematic analysis was undertaken.

RESULTS

One third of participants had not heard of the term ward round or could describe their purpose. Three main influencers on the patient experience of rounds were: self; the health system; and medical officers. No meaningful difference was found between patients in acute medicine and rehabilitation although all wanted to receive information from the senior medical officers. Patients more familiar with the health system were more active participants and took greater responsibility for their involvement in rounds and described higher satisfaction.

CONCLUSION

There is a level of acceptance within the health system that patients understand what a ward round is. However, their role on the round is complex and this may only be developed through experiencing them. High system users teach themselves to navigate rounding processes to ensure their needs are met. To ensure equity in participation patients should be educated on ward rounds, what to expect and how to they can participate.

Using behaviour change and implementation science to address low referral rates in oncology

Background

Patients undergoing surgery for bowel cancer now have a routine screening test to assess their genetic predisposition to this and other cancers (Lynch syndrome). A result indicating a high risk should trigger referral to a genetic clinic for diagnostic testing, information, and management. Appropriate management of Lynch syndrome lowers morbidity and mortality from cancer for patients and their family, but referral rates are low. The aim of this project was to increase referral rates for patients at high risk of Lynch syndrome at two Australian hospitals, using the Theoretical Domains Framework (TDF) Implementation approach.

Methods

Multidisciplinary teams at each hospital mapped the referral process and discussed barriers to referral. A 12-month retrospective audit measured baseline referral rates. The validated Influences on Patient Safety Behaviours Questionnaire was administered to evaluate barriers using the TDF. Results were discussed in focus groups and interviews, and interventions co-designed, guided by theory. Continuous monitoring audits assessed change in referral rates.

Results

Teams (n = 8, 11) at each hospital mapped referral processes. Baseline referral rates were 80% (4/5) from 71 screened patients and 8% (1/14) from 113 patients respectively. The questionnaire response rate was 51% (36/71). Most significant barrier domains were: ‘environmental context;’ ‘memory and decision making;’ ‘skills;’ and ‘beliefs about capabilities.’ Focus groups and interviews with 19 healthcare professionals confirmed these domains as significant. Fifteen interventions were proposed considering both emerging and theory-based results. Interventions included: clarification of pathology reports, education, introduction of e-referrals, and inclusion of genetic status in documentation.

Audits continued to December 2016 showing a change in pathology processes which increased the accuracy of screening. The referral rate remained low: 46% at Hospital A and 9% Hospital B. Results suggest patients who have their referral deferred for some reason are not referred later.

Conclusion

Lynch syndrome is typical of low incidence problems likely to overwhelm the system as genomic testing becomes mainstream. It is crucial for health researchers to test methods and define generalizable solutions to address this problem. Whilst our approach did not improve referrals, we have deepened our understanding of barriers to referral and approaches to low frequency conditions.

The goldilocks effect: the rhythms and pace of hospital life

BACKGROUND

While we have made gains in understanding cultures in hospitals and their effects on outcomes of care, little work has investigated how the pace of work in hospitals is associated with staff satisfaction and patient outcomes. In an era of efficiency, as speed accelerates, this requires examination.

DISCUSSION

Older studies of pace in cities found that faster lifestyles were linked to increased coronary heart disease and smoking rates, yet better subjective well-being. In this debate we propose the Goldilocks hypothesis: acute care workplaces operating at slow speeds are associated with factors such as increased wait lists, poor performance and costly care; those that are too fast risk staff exhaustion, burnout, missed care and patient dissatisfaction. We hypothesise that hospitals are best positioned by being in the Goldilocks zone, the sweet spot of optimal pace.

CONCLUSION

Testing this hypothesis requires a careful study of hospitals, comparing their pace in wards and departments with measures of performance and patient outcomes.

When complexity science meets implementation science: a theoretical and empirical analysis of systems change

BACKGROUND

Implementation science has a core aim - to get evidence into practice. Early in the evidence-based medicine movement, this task was construed in linear terms, wherein the knowledge pipeline moved from evidence created in the laboratory through to clinical trials and, finally, via new tests, drugs, equipment, or procedures, into clinical practice. We now know that this straight-line thinking was naïve at best, and little more than an idealization, with multiple fractures appearing in the pipeline.

DISCUSSION

The knowledge pipeline derives from a mechanistic and linear approach to science, which, while delivering huge advances in medicine over the last two centuries, is limited in its application to complex social systems such as healthcare. Instead, complexity science, a theoretical approach to understanding interconnections among agents and how they give rise to emergent, dynamic, systems-level behaviors, represents an increasingly useful conceptual framework for change. Herein, we discuss what implementation science can learn from complexity science, and tease out some of the properties of healthcare systems that enable or constrain the goals we have for better, more effective, more evidence-based care. Two Australian examples, one largely top-down, predicated on applying new standards across the country, and the other largely bottom-up, adopting medical emergency teams in over 200 hospitals, provide empirical support for a complexity-informed approach to implementation. The key lessons are that change can be stimulated in many ways, but a triggering mechanism is needed, such as legislation or widespread stakeholder agreement; that feedback loops are crucial to continue change momentum; that extended sweeps of time are involved, typically much longer than believed at the outset; and that taking a systems-informed, complexity approach, having regard for existing networks and socio-technical characteristics, is beneficial.

CONCLUSION

Construing healthcare as a complex adaptive system implies that getting evidence into routine practice through a step-by-step model is not feasible. Complexity science forces us to consider the dynamic properties of systems and the varying characteristics that are deeply enmeshed in social practices, whilst indicating that multiple forces, variables, and influences must be factored into any change process, and that unpredictability and uncertainty are normal properties of multi-part, intricate systems.

Medicine information exchange networks among healthcare professionals and prescribing in geriatric medicine wards

AIMS

Effective transfer of information is vital for rational drug therapy. This is particularly important for older patients, who have a high prevalence of polypharmacy and are managed by multidisciplinary teams. We aimed to assess medicine information exchange (MIE) networks in geriatric medicine wards and whether they are associated with prescribing patterns.

METHODS

We conducted network analysis in acute geriatric medicine wards from four hospitals to characterize MIE networks among multidisciplinary team members. Corresponding patient data were collected to analyze high-risk prescribing in conjunction with network characteristics.

RESULTS

We found that junior doctors, senior nurses and pharmacists were central to MIE across all four hospitals. Doctors were more likely than other professions to receive medicines information in three hospitals. Reciprocity and the tendency to communicate within one's own profession also influenced network formation. No difference was observed in prescribing practice between hospitals.

CONCLUSIONS

Understanding MIE networks can identify gaps in multidisciplinary communication that can be addressed. Networks may identify targets for dissemination of interventions to improve prescribing.

Combined Search for Lorentz Violation in Short-Range Gravity

Short-range experiments testing the gravitational inverse-square law at the submillimeter scale offer uniquely sensitive probes of Lorentz invariance. A combined analysis of results from the short-range gravity experiments HUST-2015, HUST-2011, IU-2012, and IU-2002 permits the first independent measurements of the 14 nonrelativistic coefficients for Lorentz violation in the pure-gravity sector at the level of 10^{-9}  m^{2}, improving by an order of magnitude the sensitivity to numerous types of Lorentz violation involving quadratic curvature derivatives and curvature couplings.

PO-14 - Tumour expression of coagulation proteases of the aPC pathway - a role in the pathogenesis of gynaecological cancers?

INTRODUCTION

The close relationship between coagulation, thrombosis and cancer has long been established. Gynaecological cancers, in particular ovarian cancers, carry a high risk of thrombosis but coagulation activation is also thought to play a role in tumorigenesis and metastasis. In experimental animal models of metastasis, mice with a genetic procoagulant phenotype are prone to develop metastasis and anticoagulant therapy dramatically reduces pulmonary metastasis in these models. The aPC pathway is a key natural anticoagulant pathway, in addition to its role in venous thrombosis, dysregulation of this pathway is also thought to play a role in the pathogenesis of some cancers. No data exists in ovarian and endometrial cancers.

AIM

The aim of this study is to determine the expression of key proteins of the activated protein C pathway in endometrial and ovarian malignant tumours compared to benign tumours and to assess their role in patient survival.

MATERIALS AND METHODS

RNA was extracted from 78 (54 malignant and 24 benign) fresh frozen ovarian and endometrial tumours samples. Tumour biopsies were mRNA expression of endothelial protein C receptor (EPCR), protein S (PS), protein C (PC), thrombomodulin (TM), Factor V (FV) and VIII (FVIII) and PAR-1 and PAR-2 was measured using TaqMan Low Density Arrays. mRNA fold change relative to benign expression was determined using the 2 -delta delta Ct method with 18s as internal standard. All patients gave full and informed consent and the study had the approval of the hospital ethics committee. Total cell protein was extracted from ovarian tumour tissue. Enzyme-linked immunosorbent assay (ELISA) was used to measure protein plasma expression

RESULTS

EPCR (P<0.001), protein S (P<0.0001) and Factor VIII (P<0.003) mRNA expression was significantly downregulated in malignant tumours compared with benign. Factor V and PAR-2 were significantly upregulated (P<0.001; P<0.004). Protein C was not consistently expressed. Reduced EPCR and TM protein expression was also observed in malignant tumours with increased plasma levels of Factor V. Reduced protein S and increased FV were associated with decreased survival. Plasma levels of Factor V were related to grade in the endometrial cancer group. PAR-2 mRNA expression was increased in ovarian tumours (P<0.001) however PAR-1 expression remained unchanged.

CONCLUSIONS

Our results show reduced expression of key proteins associated with activation of protein C combined with increased expression in FV in gynaecological malignancies. These changes may contribute to local thrombin production and tumour progression and metastasis. Further work is required to determine the precise mechanisms involved.

Achieving behaviour change for detection of Lynch syndrome using the Theoretical Domains Framework Implementation (TDFI) approach: a study protocol

BACKGROUND

Lynch syndrome is an inherited disorder associated with a range of cancers, and found in 2-5 % of colorectal cancers. Lynch syndrome is diagnosed through a combination of significant family and clinical history and pathology. The definitive diagnostic germline test requires formal patient consent after genetic counselling. If diagnosed early, carriers of Lynch syndrome can undergo increased surveillance for cancers, which in turn can prevent late stage cancers, optimise treatment and decrease mortality for themselves and their relatives. However, over the past decade, international studies have reported that only a small proportion of individuals with suspected Lynch syndrome were referred for genetic consultation and possible genetic testing. The aim of this project is to use behaviour change theory and implementation science approaches to increase the number and speed of healthcare professional referrals of colorectal cancer patients with a high-likelihood risk of Lynch syndrome to appropriate genetic counselling services.

METHODS

The six-step Theoretical Domains Framework Implementation (TDFI) approach will be used at two large, metropolitan hospitals treating colorectal cancer patients. Steps are: 1) form local multidisciplinary teams to map current referral processes; 2) identify target behaviours that may lead to increased referrals using discussion supported by a retrospective audit; 3) identify barriers to those behaviours using the validated Influences on Patient Safety Behaviours Questionnaire and TDFI guided focus groups; 4) co-design interventions to address barriers using focus groups; 5) co-implement interventions; and 6) evaluate intervention impact. Chi square analysis will be used to test the difference in the proportion of high-likelihood risk Lynch syndrome patients being referred for genetic testing before and after intervention implementation. A paired t-test will be used to assess the mean time from the pathology test results to referral for high-likelihood Lynch syndrome patients pre-post intervention. Run charts will be used to continuously monitor change in referrals over time, based on scheduled monthly audits.

DISCUSSION

This project is based on a tested and refined implementation strategy (TDFI approach). Enhancing the process of identifying and referring people at high-likelihood risk of Lynch syndrome for genetic counselling will improve outcomes for patients and their relatives, and potentially save public money.

Structuring successful collaboration: a longitudinal social network analysis of a translational research network

Background

In 2012 and 2013, we conducted a social network survey of a new translational research network (TRN) designed to deliver better care to cancer patients. Results of these two surveys showed that silos of researchers and clinicians existed before the TRN was established but that the network had mediated collaborative relationships. This paper reports on a third social network survey of the TRN and focusses on the structure of the collaborative arrangements among members.

Methods

Members of the TRN were invited to complete an on-line, whole network survey in May 2015. The survey asked respondents to identify personal impacts, outputs and wider outcomes attributable to their TRN membership. The final question asked respondents to select the name of TRN members with whom they had collaborated either formally or informally. For each member nominated, they were asked to say whether they had known this person before joining the TRN.

Results

Response rate was 70 %. Over 4 years, the TRN has grown in size from 68 to 244 members. Relationships within and across the TRN have become more collaborative and interactive, with 1658 collaborative ties between members and over 40 % of ties with people unknown to participants before they joined the TRN. This points to a well-functioning network which has retained its focus on the original goals of the TRN and has fostered collaboration between researchers, clinicians, managers, consumers and TRN operational staff. This survey shows that the TRN’s impact goes beyond outcomes from formal TRN-funded projects. About one third of respondents could list projects not directly funded by the TRN but which are attributed to TRN membership. Examples of practice change brought about through the TRN were given by 77 % of respondents. A substantial risk factor for the future is the high levels of dependency on key or central TRN participants.

Conclusions

The structure of the TRN with its active central actors and brokers has been able to foster collaboration on implementation initiatives that result in practice change. The role of a social professional network in driving this collaboration is shown.

Social-Professional Networks in Long-Term Care Settings With People With Dementia: An Approach to Better Care? A Systematic Review

BACKGROUND

Dementia is a syndrome associated with stigma and social isolation. Forty-two percent of people with dementia in the United States and almost 40% in the United Kingdom live in assisted living and residential care facilities. Up to 90% of residents with dementia experience behavioral and psychological symptoms of dementia (BPSD). Currently psychotropic drugs are often used to manage BPSD, despite the drugs' limited efficacy and adverse effects. Even though psychosocial approaches are as effective as medical ones without side effects, their uptake has been slow. Social networks that investigate the structure of relationships among residents and staff may represent an important resource to increase the uptake of psychosocial approaches and facilitate improvements in care.

OBJECTIVES

To conduct a systematic review of social network studies set in long-term care (LTC), including residents with dementia, and identify network factors influencing the care available to residents.

METHOD

Peer-reviewed articles across CINAHL, EMBASE, IBSS, Medline, PsychInfo, Scopus, and Web of Science were searched from January 1994 to December 2014 inclusive, using PRISMA guidelines. Studies included those examining social networks of residents or staff in LTC.

RESULTS

Nine articles from studies in the United States, Europe, Asia, and Australia met search criteria. Resident networks had few social connections. One study proposed that residents with high centrality be encouraged to welcome new residents and disseminate information. The high density in 2 staff network studies was associated with the cooperation needed to provide care to residents with dementia. Staff's boundary-spanning led to higher-status nurses becoming more involved in decision-making and problem-solving in one study. In another, the outcome was staff treating residents with more respect and actively caring for them.

CONCLUSION

These studies suggest interventions using a network approach may improve care services in LTC.

Patterns of collaboration in complex networks: the example of a translational research network

BACKGROUND

This paper examines collaboration in a complex translational cancer research network (TRN) made up of a range of hospital-based clinicians and university-based researchers. We examine the phenomenon of close-knit and often introspective clusters of people (silos) and test the extent that factors associated with this clustering (geography, profession and past experience) influence patterns of current and future collaboration on TRN projects. Understanding more of these patterns, especially the gaps or barriers between members, will help network leaders to manage subgroups and promote connectivity crucial to efficient network function.

METHODS

An on-line, whole network survey was used to collect attribute and relationship data from all members of the new TRN based in New South Wales, Australia in early 2012. The 68 members were drawn from six separate hospital and university campuses. Social network analysis with UCInet tested the effects of geographic proximity, profession, past research experience, strength of ties and previous collaborations on past, present and future intended partnering.

RESULTS

Geographic proximity and past working relationships both had significant effects on the choice of current collaboration partners. Future intended collaborations included a significant number of weak ties and ties based on other members' reputations implying that the TRN has provided new opportunities for partnership. Professional grouping, a significant barrier discussed in the translational research literature, influenced past collaborations but not current or future collaborations, possibly through the mediation of network brokers.

CONCLUSIONS

Since geographic proximity is important in the choice of collaborators a dispersed network such as this could consider enhancing cross site interactions by improving virtual communication technology and use, increasing social interactions apart from project related work, and maximising opportunities to meet members from other sites. Key network players have an important brokerage role facilitating linkages between groups.

Leadership in complex networks: the importance of network position and strategic action in a translational cancer research network

Background

Leadership behaviour in complex networks is under-researched, and little has been written concerning leadership of translational research networks (TRNs) that take discoveries made ‘at the bench’ and translate them into practices used ‘at the bedside.’ Understanding leaders’ opportunities and behaviours within TRNs working to solve this key problem in implementing evidence into clinical practice is therefore important. This study explored the network position of governing body members and perceptions of their role in a new TRN in Sydney, Australia. The paper asks three questions: Firstly, do the formal, mandated leaders of this TRN hold key positions of centrality or brokerage in the informal social network of collaborative ties? Secondly, if so, do they recognise the leadership opportunities that their network positions afford them? Thirdly, what activities associated with these key roles do they believe will maximise the TRN’s success?

Methods

Semi-structured interviews of all 14 governing body members conducted in early 2012 explored perceptions of their roles and sought comments on a list of activities drawn from review of successful transdisciplinary collaboratives combined with central and brokerage roles. An on-line, whole network survey of all 68 TRN members sought to understand and map existing collaborative connections. Leaders’ positions in the network were assessed using UCInet, and graphs were generated in NetDraw.

Results

Social network analysis identified that governing body members had high centrality and high brokerage potential in the informal network of work-related ties. Interviews showed perceived challenges including ‘silos’ and the mismatch between academic and clinical goals of research. Governing body members recognised their central positions, which would facilitate the leadership roles of leading, making decisions, and providing expert advice necessary for the co-ordination of effort and relevant input across domains. Brokerage potential was recognised in their clearly understood role of representing a specialty, campus or research group on the governing body to provide strategic linkages. Facilitation, mentoring and resolving conflicts within more localised project teams were spoken of as something ‘we do all the time anyway,’ as well as something they would do if called upon. These leadership roles are all linked with successful collaborative endeavours in other fields.

Conclusions

This paper links the empirical findings of the social network analysis with the qualitative findings of the interviews to show that the leaders’ perceptions of their roles accord with both the potential inherent in their network positions as well as actual activities known to increase the success of transdisciplinary teams. Understanding this is key to successful TRNs.

Who are the key players in a new translational research network?

Background

Professional networks are used increasingly in health care to bring together members from different sites and professions to work collaboratively. Key players within these networks are known to affect network function through their central or brokerage position and are therefore of interest to those who seek to optimise network efficiency. However, their identity may not be apparent. This study using social network analysis to ask: (1) Who are the key players of a new translational research network (TRN)? (2) Do they have characteristics in common? (3) Are they recognisable as powerful, influential or well connected individuals?

Methods

TRN members were asked to complete an on-line, whole network survey which collected demographic information expected to be associated with key player roles, and social network questions about collaboration in current TRN projects. Three questions asked who they perceived as powerful, influential and well connected. Indegree and betweenness centrality values were used to determine key player status in the actual and perceived networks and tested for association with demographic and descriptive variables using chi square analyses.

Results

Response rate for the online survey was 76.4% (52/68). The TRN director and manager were identified as key players along with six other members. Only two of nine variables were associated with actual key player status; none with perceived. The main finding was the mismatch between actual and perceived brokers. Members correctly identified two of the three central actors (the two mandated key roles director and manager) but there were only three correctly identified actual brokers among the 19 perceived brokers. Possible reasons for the mismatch include overlapping structures and weak knowledge of members.

Conclusions

The importance of correctly identifying these key players is discussed in terms of network interventions to improve efficiency.

Nurses' workarounds in acute healthcare settings: a scoping review

BACKGROUND

Workarounds circumvent or temporarily 'fix' perceived workflow hindrances to meet a goal or to achieve it more readily. Behaviours fitting the definition of workarounds often include violations, deviations, problem solving, improvisations, procedural failures and shortcuts. Clinicians implement workarounds in response to the complexity of delivering patient care. One imperative to understand workarounds lies in their influence on patient safety. This paper assesses the peer reviewed empirical evidence available on the use, proliferation, conceptualisation, rationalisation and perceived impact of nurses' use of workarounds in acute care settings.

METHODS

A literature assessment was undertaken in 2011-2012. Snowballing technique, reference tracking, and a systematic search of twelve academic databases were conducted to identify peer reviewed published studies in acute care settings examining nurses' workarounds. Selection criteria were applied across three phases. 58 studies were included in the final analysis and synthesis. Using an analytic frame, these studies were interrogated for: workarounds implemented in acute care settings by nurses; factors contributing to the development and proliferation of workarounds; the perceived impact of workarounds; and empirical evidence of nurses' conceptualisation and rationalisation of workarounds.

RESULTS

The majority of studies examining nurses' workarounds have been published since 2008, predominantly in the United States. Studies conducted across a variety of acute care settings use diverse data collection methods. Nurses' workarounds, primarily perceived negatively, are both individually and collectively enacted. Organisational, work process, patient-related, individual, social and professional factors contribute to the proliferation of workarounds. Group norms, local and organisational culture, 'being competent', and collegiality influence the implementation of workarounds.

CONCLUSION

Workarounds enable, yet potentially compromise, the execution of patient care. In some contexts such improvisations may be deemed necessary to the successful implementation of quality care, in others they are counterproductive. Workarounds have individual and cooperative characteristics. Few studies examine nurses' individual and collective conceptualisation and rationalisation of workarounds or measure their impact. The importance of displaying competency (image management), collegiality and organisational and cultural norms play a role in nurses' use of workarounds.

Bridges, brokers and boundary spanners in collaborative networks: a systematic review

BACKGROUND

Bridges, brokers and boundary spanners facilitate transactions and the flow of information between people or groups who either have no physical or cognitive access to one another, or alternatively, who have no basis on which to trust each other. The health care sector is a context that is rich in isolated clusters, such as silos and professional "tribes," in need of connectivity. It is a key challenge in health service management to understand, analyse and exploit the role of key agents who have the capacity to connect disparate groupings in larger systems.

METHODS

The empirical, peer reviewed, network theory literature on brokerage roles was reviewed for the years 1994 to 2011 following PRISMA guidelines.

RESULTS

The 24 articles that made up the final literature set were from a wide range of settings and contexts not just healthcare. Methods of data collection, analysis, and the ways in which brokers were identified varied greatly. We found four main themes addressed in the literature: identifying brokers and brokerage opportunities, generation and integration of innovation, knowledge brokerage, and trust. The benefits as well as the costs of brokerage roles were examined.

CONCLUSIONS

Collaborative networks by definition, seek to bring disparate groups together so that they can work effectively and synergistically together. Brokers can support the controlled transfer of specialised knowledge between groups, increase cooperation by liaising with people from both sides of the gap, and improve efficiency by introducing "good ideas" from one isolated setting into another.There are significant costs to brokerage. Densely linked networks are more efficient at diffusing information to all their members when compared to sparsely linked groups. This means that while a bridge across a structural hole allows information to reach actors that were previously isolated, it is not the most efficient way to transfer information. Brokers who become the holders of, or the gatekeepers to, specialised knowledge or resources can become overwhelmed by the role and so need support in order to function optimally.

Network structure and the role of key players in a translational cancer research network: a study protocol

INTRODUCTION

Translational research networks are a deliberate strategy to bridge the gulf between biomedical research and clinical practice through interdisciplinary collaboration, supportive funding and infrastructure. The social network approach examines how the structure of the network and players who hold important positions within it constrain or enable function. This information can be used to guide network management and optimise its operations. The aim of this study was to describe the structure of a translational cancer research network (TCRN) in Australia over its first year, identify the key players within the network and explore these players' opportunities and constraints in maximising important network collaborations.

METHODS AND ANALYSIS

This study deploys a mixed-method longitudinal design using social network analysis augmented by interviews and review of TCRN documents. The study will use network documents and interviews with governing body members to explore the broader context into which the network is embedded as well as the perceptions and expectations of members. Of particular interest are the attitudes and perceptions of clinicians compared with those of researchers. A co-authorship network will be constructed of TCRN members using journal and citation databases to assess the success of past pre-network collaborations. Two whole network social network surveys will be administered 12 months apart and parameters such as density, clustering, centrality and betweenness centrality computed and compared using UCINET and Netdraw. Key players will be identified and interviewed to understand the specific activities, barriers and enablers they face in that role.

ETHICS AND DISSEMINATION

Ethics approvals were obtained from the University of New South Wales, South Eastern Sydney Northern Sector Local Health Network and Calvary Health Care Sydney. Results will be discussed with members of the TCRN, submitted to relevant journals and presented as oral presentations to clinicians, researchers and policymakers.

A private allele ubiquitous in the Americas

The three-wave migration hypothesis of Greenberg et al. has permeated the genetic literature on the peopling of the Americas. Greenberg et al. proposed that Na-Dene, Aleut-Eskimo and Amerind are language phyla which represent separate migrations from Asia to the Americas. We show that a unique allele at autosomal microsatellite locus D9S1120 is present in all sampled North and South American populations, including the Na-Dene and Aleut-Eskimo, and in related Western Beringian groups, at an average frequency of 31.7%. This allele was not observed in any sampled putative Asian source populations or in other worldwide populations. Neither selection nor admixture explains the distribution of this regionally specific marker. The simplest explanation for the ubiquity of this allele across the Americas is that the same founding population contributed a large fraction of ancestry to all modern Native American populations.

A formal test of linguistic and genetic coevolution in native Central and South America

This paper investigates a mechanism of linguistic and genetic coevolution in Native Central and South America. This mechanism proposes that a process of population fissions, expansions into new territories, and isolation of ancestral and descendant groups will produce congruent language and gene trees. To evaluate this population fissions mechanism, we collected published mtDNA sequences for 1,381 individuals from 17 Native Central and South American populations. We then tested the hypothesis that three well-known language classifications also represented the genetic structure of these populations. We rejected the hypothesis for each language classification. Our tests revealed linguistic and genetic correspondence in several shallow branches common to each classification, but no linguistic and genetic correspondence in the deeper branches contained in two of the language classifications. We discuss the possible causes for the lack of congruence between linguistic and genetic structure in the region, and describe alternative mechanisms of linguistic and genetic correspondence and their predictions.

Early experience and serotonin transporter gene variation interact to influence primate CNS function

Nonhuman primates offer unique opportunities to study the effects of genes, environments, and their interaction, on physiology and complex behavior. We examined genotype and early environment contributions to CNS function in a large sample of rhesus monkeys. In humans, length variation of the serotonin (5-HT) transporter (5-HTT) gene-linked polymorphic region (5-HTTLPR) that results in allelic variation in 5-HTT expression is associated with decreased serotonergic function and 5-HT-mediated psychopathology. We report that an analogous variation of the gene's regulatory region in monkeys interacts with early experience to affect central 5-HT functioning. Monkeys with deleterious early rearing experiences were differentiated by genotype in cerebrospinal fluid concentrations of the 5-HT metabolite, 5-hydroxyindoleacetic acid, while monkeys reared normally were not. These findings demonstrate an environment-dependent effect of the rh5-HTTLPR genotype on CNS 5-HT function and suggest nonhuman primates may provide an important avenue for investigating gene/environment interactions using candidate genes for physiological and behavioral traits.
