Abstract: Workspaces are socially constructed environments where social relationships are produced, reproduced, challenged and transformed. Their primary function is to support high-quality service delivery to the benefit of ‘patients’. They are also settings where employees can work effectively, in a safe and healthy environment, delivering a high-quality service according to a ‘Work-As-Done’ rather than a ‘Work-As-Imagined’ model. However, hospital design is currently based on a managerial understanding of work accomplishments, often falling short of understanding what is actually happening on the ground. Furthermore, the research landscape lacks rigorous assessment of these complex sociological and health research concepts, either within the Australian context where this protocol is set, or internationally. This paper describes an innovative protocol aimed at examining healthcare employees’ and organisations’ concerns and beliefs in workspace design. It outlines research investigating the effect of workspace use on productivity, health and safety and worker satisfaction, to clarify Work-As-Done, while creating healthy and more fulfilling environments. This is a proof-of-concept study, taking place between June 2018 and April 2019, employing a multimethod, qualitative approach for in-depth assessment of one Australian, private, university hospital environment, using as its ‘case’ the Gastroenterology Surgical Unit. It involves (1) observations and informal interviews (shadowing) with employees and patients as they traverse hospital spaces and (2) visual data of spatial use. Fieldnotes will be analysed thematically, and visual data analysed using a predefined schematic framework (a visual taxonomy). Overarching themes and categories will be considered corroboratively, mixing visual and textual data to build an iterative and dynamic picture. Ethical considerations will be discussed, while approval has been granted by the University’s Human Research Ethics Committee (HREC/5201800282), along with Governance approved by the Health Clinical Research Executive (CRG2018005). Study results will be disseminated through publications, research conferences and public reports.

Abstract: Randomised controlled trials (RCTs), while still considered the gold standard approach in medical research, can encounter impediments to their successful conduct and the dissemination of results. Pretrial qualitative research can usefully address some of these impediments, including recruitment and retention, ethical conduct, and preferred methods of dissemination. However, pretrial qualitative work is rarely undertaken in audiology. The Comparison of outcomes with hearing aids and cochlear implants in adults with moderately severe-to-profound bilateral sensorineural hearing loss (COACH) is a proposed RCT aiming to clarify when hearing aids (HAs) or cochlear implants (CIs) are the most suitable for different degrees of hearing loss and for which kinds of patients. q-COACH is a pretrial, qualitative study examining stakeholders’ experiences of HAs and CIs, current clinical practices and stakeholders’ perspectives of the design, conduct and dissemination plans for the proposed COACH study. Twenty-four participants including general practitioners, audiologists, adult HA users, and adult support networks undertook either semi-structured in idual or paired interviews and completed demographic questionnaires. Data were analysed thematically. Four key themes arose from this study: 1) rethinking s ling and recruitment strategies, 2) ethical considerations, 3) refining trial conduct, and 4) interconnected, appropriate and accessible methods of results dissemination. This qualitative investigation identified key considerations for the proposed RCT design, conduct and dissemination to help with successful implementation of COACH, and to indicate a plan of action at all RCT stages that would be acceptable to potential participants. By drawing on the perspectives of multiple key stakeholders and including a more general discussion of their experience and opinions of hearing loss, hearing device use and service availability, the study revealed experiential and ethical paradigms in which stakeholders operate. In so doing, q-COACH has exposed the benefits of preliminary qualitative investigations that enable detailed and rich understandings of the phenomenon at stake, forestalling problems and improving the quality of trial design, conduct and dissemination, while informing future RCT development discussions.

Abstract: Realist synthesis. Large-scale hospital improvement initiatives can standardise healthcare across multiple sites but results are contingent on the implementation strategies that complement them. The benefits of these implemented interventions are rarely able to be replicated in different contexts. Realist studies explore this phenomenon in depth by identifying underlying context–mechanism–outcome interactions. To review implementation strategies used in large-scale hospital initiatives and hypothesise initial programme theories for how they worked across different contexts. An iterative, four-step process was applied. Step 1 explored the concepts inherent in large-scale interventions using database searches and snowballing. Step 2 identified strategies used in their implementation. Step 3 identified potential initial programme theories that may explain strategies’ mechanisms. Step 4 focused on one strategy-theory pairing to develop and test context–mechanism–outcome hypotheses. Data was drawn from searches (March–May 2020) of MEDLINE, Embase, PubMed and CINAHL, snowballed from key papers, implementation support websites and the expertise of the research team and experts. Inclusion criteria: reported implementation of a large-scale, multisite hospital intervention. RAMESES reporting standards were followed. Concepts were identified from 51 of 381 articles. Large-scale hospital interventions were characterised by a top–down approach, external and internal support and use of evidence-based interventions. We found 302 reports of 28 different implementation strategies from 31 reviews (from a total of 585). Formal theories proposed for the implementation strategies included Diffusion of Innovation, and Organisational Readiness Theory. Twenty-three context–mechanism–outcome statements for implementation strategies associated with planning and assessment activities were proposed. Evidence from the published literature supported the hypothesised programme theories and were consistent with Organisational Readiness Theory’s tenets. This paper adds to the literature exploring why large-scale hospital interventions are not always successfully implemented and suggests 24 causative mechanisms and contextual factors that may drive outcomes in the planning and assessment stage.

Abstract: Achieving seizure control through resective brain surgery is a major predictor of improved quality of life (QOL) among people with refractory (drug-resistant) epilepsy. Nevertheless, QOL is a comprehensive and dynamic construct, consisting of broad dimensions such as physical health, psychosocial well-being, level of independence, social relationships, and beyond. This study highlights the interlinkage and complementarity of these erse dimensions, and how in practice, patients, clinicians, and others in a social support system can actively promote QOL among surgery patients. Twenty-one qualitative in-depth interviews with patients with refractory epilepsy who are either undergoing presurgical assessment or postsurgery follow-up were conducted, to consider their perspective on QOL in relation to their experience of illness and surgical treatment. Data were thematically analyzed, resulting in three key thematic findings. (1) A myriad of QOL dimensions are highly interrelated and interdependent with mutual 'spin-off' effects: Uncontrolled seizures impacted beyond physical and cognitive health, disrupting important social identities such as being successful parents, spouses, and career professionals. The desire for good clinical outcomes from surgery was justified against the need to mitigate these social and personal concerns. (2) In postsurgery care, there were complementary effects of clinical interventions and social factors on patients' QOL. Psychosocial well-being was supported by a combination of improved physical health, self-confidence, psychological interventions, and social support from employers and educators who were sensitive to patients' specialized needs. (3) Engaging in education, employment, and government services influenced not only socioeconomic well-being, but also a sense of social inclusion. Advocacy made on behalf of patients by clinicians and family members has helped to better manage patients' eligibility for social services provision. Quality of life is achieved through a comprehensive and interactive social process, and not simply an outcome measure of clinical treatment. The responses and interactions of many others within the patients' life and treatment process, including family members, clinicians, and social service workers, can culminate to influence QOL, highlighting the importance of a relational and social determinants perspective in patient care.

Abstract: To undertake a synthesis of evidence-based research for seven innovative models of care to inform the development of new hospitals. Umbrella review. Interventions delivered inside and outside of acute care settings. Children and adults with one or more identified acute or chronic health conditions. PsycINFO, Ovid MEDLINE and CINAHL. Clinical indicators and mortality, healthcare utilisation, quality of life, self-management and self-care and patient knowledge. A total of 66 reviews were included, synthesising evidence from 1272 primary studies across the 7 models of care. Virtual care was the most common model studied, addressed by 47 (73%) of the reviews. Common outcomes evaluated across reviews were clinical indicators and mortality, healthcare utilisation, self-care and self-management, patient knowledge, quality of life and cost-effectiveness. The findings indicate that the innovative models of healthcare we identified in this review may be effective in managing patients with a range of acute and chronic conditions. Most of the included reviews reported evidence of comparable or improved care. A consideration of local infrastructure and in idual patient characteristics, such as health literacy, may be critical in determining the suitability of models of care for patients and their implementation in local health systems. 10.17605/OSF.IO/PS6ZU.

Abstract: Emergency department (ED) care must adapt to meet current and future demands. In Australia, ED quality measures (eg, prolonged length of stay, re-presentations or patient experience) are worse for older adults with multiple comorbidities, people who have a disability, those who present with a mental health condition, Indigenous Australians, and those with a culturally and linguistically erse (CALD) background. Strengthened ED performance relies on understanding the social and systemic barriers and preferences for care of these different cohorts, and identifying viable solutions that may result in sustained improvement by service providers. A collaborative 5-year project (MyED) aims to codesign, with ED users and providers, new or adapted models of care that improve ED performance, improve patient outcomes and improve patient experience for these five cohorts. Experience-based codesign using mixed methods, set in three hospitals in one health district in Australia. This protocol introduces the staged and incremental approach to the whole project, and details the first research elements: ethnographic observations at the ED care interface, interviews with providers and interviews with two patient cohorts—older adults and adults with a CALD background. We aim to s le a erse range of participants, carefully tailoring recruitment and support. Ethics approval has been obtained from the Western Sydney Local Health District Human Research Ethics Committee (2022/PID02749-2022/ETH02447). Prior informed written consent will be obtained from all research participants. Findings from each stage of the project will be submitted for peer-reviewed publication. Project outputs will be disseminated for implementation more widely across New South Wales, Australia.

Abstract: Large-scale, multisite hospital improvement initiatives can advance high-quality care for patients. Implementation support is key to adoption of change in this context. Strategies that foster collaboration within local teams, across sites and between initiative developers and users are important. However not all implementation strategies are successful in all settings, sometimes realising poor or unintended outcomes. Our objective here is to develop guiding principles for effective collaborative implementation strategies for multi-site hospital initiatives. Mixed-method realist evaluation. Realist studies aim to examine the underlying theories that explain differing outcomes, identifying mechanisms and contextual factors that may trigger them. We report on collaborative strategies used in four multi-site initiatives conducted in all public hospitals in New South Wales, Australia (n ). Using an iterative process, information was gathered on collaborative implementation strategies used, then initial programme theories hypothesised to underlie the strategies’ outcomes were surfaced using a realist dialogic approach. A realist interview schedule was developed to elicit evidence for the posited initial programme theories. Fourteen participants from 20 key informants invited participated. Interviews were conducted via Zoom, transcribed and analysed. From these data, guiding principles of fostering collaboration were developed. Six guiding principles were distilled: (1) structure opportunities for collaboration across sites (2) facilitate meetings to foster learning and problem-solving across sites (3) broker useful long-term relationships (4) enable support agencies to assist implementers by giving legitimacy to their efforts in the eyes of senior management (5) consider investment in collaboration as effective well beyond the current projects (6) promote a shared vision and build momentum for change by ensuring inclusive networks where everyone has a voice. Structuring and supporting collaboration in large-scale initiatives is a powerful implementation strategy if contexts described in the guiding principles are present.

Abstract: Value-based healthcare delivery models have emerged to address the unprecedented pressure on long-term health system performance and sustainability and to respond to the changing needs and expectations of patients. Implementing and scaling the benefits from these care delivery models to achieve large-system transformation are challenging and require consideration of complexity and context. Realist studies enable researchers to explore factors beyond ‘what works’ towards more nuanced understanding of ‘what tends to work for whom under which circumstances’. This research proposes a realist study of the implementation approach for seven large-system, value-based healthcare initiatives in New South Wales, Australia, to elucidate how different implementation strategies and processes stimulate the uptake, adoption, fidelity and adherence of initiatives to achieve sustainable impacts across a variety of contexts. This exploratory, sequential, mixed methods realist study followed RAMESES II (Realist And Meta-narrative Evidence Syntheses: Evolving Standards) reporting standards for realist studies. Stage 1 will formulate initial programme theories from review of existing literature, analysis of programme documents and qualitative interviews with programme designers, implementation support staff and evaluators. Stage 2 envisages testing and refining these hypothesised programme theories through qualitative interviews with local hospital network staff running initiatives, and analyses of quantitative data from the programme evaluation, hospital administrative systems and an implementation outcome survey. Stage 3 proposes to produce generalisable middle-range theories by synthesising data from context–mechanism–outcome configurations across initiatives. Qualitative data will be analysed retroductively and quantitative data will be analysed to identify relationships between the implementation strategies and processes, and implementation and programme outcomes. Mixed methods triangulation will be performed. Ethical approval has been granted by Macquarie University (Project ID 23816) and Hunter New England (Project ID 2020/ETH02186) Human Research Ethics Committees. The findings will be published in peer-reviewed journals. Results will be fed back to partner organisations and roundtable discussions with other health jurisdictions will be held, to share learnings.

Abstract: Implementation science in healthcare aims to understand how to get evidence into practice. Once this is achieved in one setting, it becomes increasingly difficult to replicate elsewhere. The problem is often attributed to differences in context that influence how and whether implementation strategies work. We argue that realist research paradigms provide a useful framework to express the effect of contextual factors within implementation strategy causal processes. Realist studies are theory-driven evaluations that focus on understanding how and why interventions work under different circumstances. They consider the interaction between contextual circumstances, theoretical mechanisms of change and the outcomes they produce, to arrive at explanations of conditional causality (i.e., what tends to work, for whom, under what circumstances). This Commentary provides ex le applications using preliminary findings from a large realist implementation study of system-wide value-based healthcare initiatives in New South Wales, Australia. If applied judiciously, realist implementation studies may represent a sound approach to help optimise delivery of the right care in the right setting and at the right time.

Abstract: Addressing clinical variation in elective surgery is challenging. A key issue is how to gain consensus between largely autonomous clinicians. Understanding how the consensus process works to develop and implement perioperative pathways and the impact of these pathways on reducing clinical variation can provide important insights into the effectiveness of the consensus process. The primary objective of this study is to understand the implementation of an organisationally supported, consensus approach to implement perioperative care pathways in a private healthcare facility and to determine its impact. A mixed-methods Effectiveness-Implementation Hybrid (type III) pre–post study will be conducted in one Australian private hospital. Five new consensus-based perioperative care pathways will be developed and implemented for specific patient cohorts: spinal surgery, radical prostatectomy, cardiac surgery, bariatric surgery and total hip and knee replacement. The in idual components of these pathways will be confirmed as part of a consensus-building approach and will follow a four-stage implementation process using the Exploration, Preparation, Implementation and Sustainment framework. The process of implementation, as well as barriers and facilitators, will be evaluated through semistructured interviews and focus groups with key clinical and non-clinical staff, and participant observation. We anticipate completing 30 interviews and 15–20 meeting observations. Administrative and clinical end-points for at least 152 participants will be analysed to assess the effectiveness of the pathways. This study received ethical approval from Macquarie University Human Research Ethics Medical Sciences Committee (Reference No: 520221219542374). The findings of this study will be disseminated through peer-reviewed publications, conference presentations and reports for key stakeholders.

Abstract: Realist evaluation is a method increasingly adopted to provide an understanding of how and why a program works, for whom, and under what circumstances. Initial program theories (IPT) are the crucial starting point of any realist evaluation, however descriptions about how they are developed in practice remain under-reported in the published literature. This article argues for the value of genuine research-group conversations using David Bohm’s concept of dialogue in realist research. We label it the realist dialogic approach. We draw out the relational qualities as well as the contextual circumstances of dialogue through our development of IPT and interview guides for a research study on the implementation and scaling of a large-system value-based program to transform complex health services. We selected the relevant middle-range theories, conducted a literature review, and drew on informal discussions with key stakeholders, to develop IPT through research-group conversations. The benefits of this approach were: 1) development of rigorous, novel, deep and well-tailored IPT, 2) detailed understanding of the complex intervention under investigation and development of rapport and networks with participants, 3) empirically grounded Context-Mechanism-Outcome (CMO) configurations, predicated on suitable abstract and contextually-contingent middle-range theories, and 4) productive research team interactions which supported the entire research process. The challenges of this approach include: 1) establishing and retaining a sense of humility across the research team, 2) contextual circumstances can hinder dialogic relationship, and 3) time and resource heavy. This paper uses middle-range theory and ethnographic insights to advance the existing practice of realist evaluations and offer transferable lessons to other scholars considering similar approaches. Moreover, we content that the use of middle-range theory to extend the methodological literature is a novel contribution to realist work.

Abstract: Good workspace design is key to the quality of work, safety, and wellbeing for workers, yet we lack vital knowledge about optimal hospital design to meet healthcare workforce needs. This study used novel mobile methods to examine the concept of Work-as-Done and the effect of workspace-use on healthcare professional practice, productivity, health and safety in an Australian university hospital. This pilot study took place in one gastroenterological surgical unit between 2018 and 2019. Data collection involved 50 h of observations and informal conversations, followed by interpretation of five architectural plans and 45 photographs. Fieldnotes were thematically analysed and corroborated by analysis of visual data using a predefined taxonomy. Six themes were identified, revealing spaces that both support and hinder Work-as-Done. Fit-for-purpose spaces facilitated effective communication between staff, patients and families, conferred relative comfort and privacy, and supported effective teamwork. Unfit-for-purpose spaces were characterised by disruptions to work practices, disharmony among team members, and physical discomfort for staff. Staff employed workarounds to manage unfit-for-purpose spaces. The results identified negative impacts of negotiating unfit-for-purpose workspaces on the work and wellbeing of staff. While the use of workarounds and adaptations enable staff to maintain everyday working practices, they can also lead to unexpected consequences. Results indicated the need to identify and support fit-for-purpose spaces and minimize the detrimental qualities of unfit-for-purpose spaces. This study showed that mobile methods were suitable for examining Work-as-Done in a fast-moving, adaptive hospital setting.

Abstract: Hearing loss is a common chronic problem which can be effectively managed with hearing devices. At present, only a limited number of people with hearing loss use hearing aids (HAs) and cochlear implants (CIs) to improve hearing and sound quality and enhance quality of life. Clinical equipoise, by which we mean healthcare professional uncertainty about which treatment options are the most efficacious due to the lack of evidence-based information, can lead to inconsistent and poorly informed referral processes for hearing devices. A randomised controlled trial (RCT) that offers high-quality, generalisable information is needed to clarify which hearing device (HA or CI) is more suitable for different degrees of hearing loss and for which kinds of patients. Qualitative research can improve this RCT, by gathering the information on patient and provider perspectives, attitudes and values, which can inform design, conduct and information dissemination, either during preparatory stages of an intervention, or as a fully integrated methodology. The Comparison of Outcomes with hearing Aids and Cochlear implants in adults with moderately severe-to-profound bilateral sensorineural Hearing loss (COACH) study is being planned as an RCT with a qualitative arm (the qualitative COACH study, q-COACH), acting as a pretrial intervention examining views of HAs, CIs, equipoise and the impetus for an RCT of this nature. The q-COACH study involves semistructured interviews and a demographic questionnaire which will be collected from four participant cohorts: General Practitioners (GPs) and Ear, Nose and Throat Surgeons (ENTs) audiologists adult HA users and their support networks. Data will be analysed thematically and through descriptive statistics. Macquarie University Human Research Ethics Committee, Australia, granted ethical approval (no. 5201833514848). Peer-reviewed journal articles, research conferences and a final report will present study findings.

Abstract: 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. 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. 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. 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. PROSPERO 162812
