Background There is some evidence to suggest that animal-assisted interventions can have beneficial impact for residents in long-term care, but the focus of the evidence has largely been on behavioural and psychosocial measured outcomes. Animals, either as companion animals or in the form of pet/animal-assisted therapy, may provide benefits in the form of social contact, as well as opportunities for sensory experiences and meaningful engagement not picked up by outcome tools. This review aimed to create a state-of-knowledge synthesis, bringing together qualitative and quantitative findings, on the impact of animal-human interaction on care home residents and care home staff. Methods Fourteen databases were searched from inception to July 2020. Forward and backward citation chasing of included articles was conducted. Screening was undertaken independently by a team of reviewers. Thematic synthesis and meta-analysis were used to synthesise the qualitative and quantitative data. Results Thirty-four studies, published in 40 articles (20 qualitative and 20 quantitative) were included. Five themes relating to resident wellbeing were identified in the qualitative evidence synthesis. These were animals as ‘living beings’, reminiscence and storytelling, caring (as ‘doing’ and ‘feeling’), respite (from loneliness, institutionalisation, and illness), and sensory engagement. A sixth theme related to staff perceptions and wellbeing, and a seventh to animal health and wellbeing. Maintaining identity was identified as an overarching theme. The majority of randomised trials had small sample sizes and were rated as low quality, mostly showing no evidence of beneficial effect. There was, however, limited evidence of a positive effect of pet/animal interaction on outcomes of loneliness, anxiety and depression, supporting the themes of respite and sensory engagement. Conclusions The presence of animals can significantly impact the health and wellbeing of some care home residents. Residents had meaningful relationships with animals and derived pleasure and comfort from them. Interacting with animals offered residents a way to maintain a sense of self in the care homes, and with support, residents with dementia could also express their identities. Facilitating residents to interact with animals as part of person-centred care may also help residents to feel ‘at home’ in the care home.

Aim:\ud This systematic review identifies, appraises and synthesizes the evidence on the provision of fundamental nursing care to hospitalized patients with a highly infectious virus and the effectiveness of adaptations to overcome barriers to care.\ud \ud Design:\ud Systematic review.\ud \ud Data Sources:\ud In July 2020, we searched Medline, PsycINFO (OvidSP), CINAHL (EBSCOhost), BNI (ProQuest), WHO COVID-19 Database (https://search.bvsalud.org/) MedRxiv (https://www.medrxiv.org/), bioRxiv (https://www.biorxiv.org/) and also Google Scholar, TRIP database and NICE Evidence, forwards citation searching and reference checking of included papers, from 2016 onwards.\ud \ud Review Methods:\ud We included quantitative and qualitative research reporting (i) the views, perceptions and experiences of patients who have received fundamental nursing care whilst in hospital with COVID-19, MERS, SARS, H1N1 or EVD or (ii) the views, perceptions and experiences of professional nurses and non-professionally registered care workers who have provided that care. We included review articles, commentaries, protocols and guidance documents. One reviewer performed data extraction and quality appraisal and was checked by another person.\ud \ud Results:\ud Of 3086 references, we included 64 articles; 19 empirical research and 45 review articles, commentaries, protocols and guidance documents spanning five pandemics. Four main themes (and 11 sub-themes) were identified. Barriers to delivering fundamental care were wearing personal protective equipment, adequate staffing, infection control procedures and emotional challenges of care. These barriers were addressed by multiple adaptations to communication, organization of care, staff support and leadership.\ud \ud Conclusion:\ud To prepare for continuation of the COVID-19 pandemic and future pandemics, evaluative studies of adaptations to fundamental healthcare delivery must be prioritized to enable evidence-based care to be provided in future.\ud \ud Impact:\ud Our review identifies the barriers nurses experience in providing fundamental care during a pandemic, highlights potential adaptations that address barriers and ensure positive healthcare experiences and draws attention to the need for evaluative research on fundamental care practices during pandemics.

Our previous work identified that nine leading guidance documents for seven different types of systematic review advocated the same process of literature searching. We defined and illustrated this process and we named it ‘the Conventional Approach’. The Conventional Approach appears to meet the needs of researchers undertaking literature searches for systematic reviews of clinical interventions. In this article, we report a new and alternate process model of literature searching called ‘A Tailored Approach’. A Tailored Approach is indicated as a search process for complex reviews which do not focus on the evaluation of clinical interventions. The aims of this article are to (1) explain the rationale for, and the theories behind, the design of A Tailored Approach; (2) report the current conceptual illustration of A Tailored Approach and to describe a user’s interaction with the process model; and (3) situate the elements novel to A Tailored Approach (when compared with the Conventional Approach) in the relevant literature. A Tailored Approach suggests investing time at the start of a review, to develop the information needs from the research objectives, and to tailor the search approach to studies or data. Tailored Approaches should be led by the information specialist (librarian) but developed by the research team. The aim is not necessarily to focus on comprehensive retrieval. Further research is indicated to evaluate the use of supplementary search methods, methods of team-working to define search approaches, and to evaluate the use of conceptual models of information retrieval for testing and evaluation.

Objectives We set out to map the quantitative and qualitative systematic review evidence available to inform the optimal prescribing of drugs that can cause dependency (benzodiazepines, opioids, non-benzodiazepine hypnotics, gabapentinoids and antidepressants). We also consider how this evidence can be used to inform decision-making in the patient care pathway for each type of medication. Methods Eight bibliographic databases were searched for the period 2010 to 2020. All included reviews were initially appraised using four items from the Collaboration for Environmental Evidence Synthesis Assessment Tool, with reviews that scored well on all items proceeding to full quality appraisal. Key characteristics of the reviews were tabulated, and each review was incorporated into an evidence and gap map based on a patient care pathway. The care pathway was based upon an amalgamation of existing NICE guidelines and feedback from clinical and patient stakeholders. Results We identified 80 relevant reviews and displayed them in an evidence and gap map. The evidence included in these reviews was predominantly of low overall quality. Areas where systematic reviews have been conducted include barriers and facilitators to the deprescribing of drugs that may cause dependency, although we identified little evidence exploring the experiences or evaluations of specific interventions to promote deprescribing. All medications of interest, apart from gabapentinoids, were included in at least one review. Conclusions The evidence and gap map provides an interactive resource to support (i) policy developers and service commissioners to use evidence in the development and delivery of services for people receiving a prescription of drugs that may cause dependency, where withdrawal of medication may be appropriate, (ii) the clinical decision-making of prescribers and (iii) the commissioning of further research. The map can also be used to inform the commissioning of further systematic reviews. To address the concerns regarding the quality of the existing evidence based raised in this report, future reviews should be conducted according to best-practice guidelines. Systematic reviews focusing on evaluating interventions to promote deprescribing would be particularly beneficial, as would reviews focusing on addressing the paucity of evidence regarding the deprescription of gabapentinoids.

Data availability: No data was used for the research described in the article. Short Communication Copyright © 2023 The Authors. Flame retardants are chemical substances that are intended to mitigate fire safety risks posed by a range of goods including furniture, electronics, and building insulation. There are growing concerns about their effectiveness in ensuring fire safety and the potential harms they pose to human health and the environment. In response to these concerns, on 13 June 2022, a roundtable of experts was convened by the UKRI Six Clean Air Strategic Priorities Fund programme 7. The meeting produced a Consensus Statement that summarises the issues around the use of flame retardants, laying out a series of policy recommendations that should lead to more effective fire safety measures and reduce the human and environmental health risks posed by these potentially toxic chemicals.

This workshop focuses on what the Collaboration for Environmental Evidence (CEE), a key non-profit systematic review coordinating body, can provide by way of support to anyone wishing to conduct a robust evidence synthesis in the field of environmental science, conservation, ecology, evolution, etc. The workshop will involve a presentation of the organisation, its role and free services and support, followed by a Q&A.

Background Many conservation management interventions have been set up to bring win–win outcomes for both biodiversity conservation and the well-being of the local communities. Nevertheless, the implementation process of marine protected areas (MPAs) can generate unexpected outcomes and fail to reach its objectives in addressing communities’ challenges. Therefore, it is crucial to have a better understanding of how MPAs influence the socioeconomic aspects of the coastal communities. This paper describes the protocol to conduct a systematic review which aims to explore and review the evidence that reflects the outcomes of marine site protection on poverty reduction in terms of economic and material living standards among the coastal communities in Southeast Asia. The review question is “What are the outcomes of marine site protection implementation on poverty in terms of material and economic living standards of coastal communities in Southeast Asia?”. Methods The systematic review uses rigorous search strategies and selection methods based on pre-defined eligibility criteria to identify and examine published journal articles and grey literature that are available on the review topic. Relevant studies and grey literature will be extracted from a recent systematic map of the evidence documenting the effect of marine or coastal nature conservation or natural resource management activities on human well-being in Southeast Asia. We will search online databases including Web of Science Core Collection, Ovid Medline®, Environmental Complete, Scopus, as well as Google Scholar and sources of grey literature for any additional literature available since the evidence map was created. For this review, the populations of interest are from coastal communities in the Southeast Asia region. Comparators to marine site protection will be no intervention and/or pre-MPA implementation. The economic and material living standards, which are the poverty domains, will be evaluated as outcomes. Once we have identified relevant literature, we will perform a critical appraisal, data extraction, and synthesis appropriate to the type of literature found, to investigate the effect of marine site protection on poverty reduction.

© 2019 The Authors. Research Synthesis Methods published by John Wiley & Sons Ltd The incorporation of evidence derived from multiple research designs into one single synthesis can enhance the utility of systematic reviews making them more worthwhile, useful, and insightful. Methodological guidance for mixed-methods synthesis continues to emerge and evolve but broadly involves a sequential, parallel, or convergent approach according to the degree of independence between individual syntheses before they are combined. We present two case studies in which we used novel and innovative methods to draw together the findings from individual but related quantitative and qualitative syntheses to aid interpretation of the overall evidence base. Our approach moved beyond making a choice between parallel, sequential, or convergent methods to interweave the findings of individual reviews and offers three key innovations to mixed-methods synthesis methods: The use of intersubjective questions to understand the findings of the individual reviews through different lenses, Immersion of key reviewers in the entirety of the evidence base, and Commencing the process during the final stages of the synthesis of individual reviews, at a point where reviewers are developing an understanding of initial findings. Underlying our approach is the process of exploration and identification of links between and across review findings, an approach that is fundamental to all evidence syntheses but usually occurs at the level of the study. Adapting existing methods for exploring and identifying patterns and links between and across studies to interweave the findings between and across reviews may prove valuable.

Background Antimicrobial resistance (AMR) is predicted to become the leading cause of death by 2050 with antibiotic resistance being an important component. Anthropogenic pollution introduces antibiotic resistant bacteria (ARB) and antibiotic resistance genes (ARGs) to the natural environment. Currently, there is limited empirical evidence demonstrating whether humans are exposed to environmental AMR and whether this exposure can result in measurable human health outcomes. In recent years there has been increasing interest in the role of the environment and disparate evidence on transmission of AMR to humans has been generated but there has been no systematic attempt to summarise this. We aim to create two systematic maps that will collate the evidence for (1) the transmission of antibiotic resistance from the natural environment to humans on a global scale and (2) the state of antibiotic resistance in the environment in the United Kingdom. Methods Search strategies were developed for each map. Searches were undertaken in 13 bibliographic databases. Key websites were searched and experts consulted for grey literature. Search results were managed using EndNote X8. Titles and abstracts were screened, followed by the full texts. Articles were double screened at a minimum of 10% at both stages with consistency checking and discussion when disagreements arose. Data extraction occurred in Excel with bespoke forms designed. Data extracted from each selected study included: bibliographic information; study site location; exposure source; exposure route; human health outcome (Map 1); prevalence/percentage/abundance of ARB/antibiotic resistance elements (Map 2) and study design. EviAtlas was used to visualise outputs. Results For Map 1, 40 articles were included, from 11,016 unique articles identified in searches, which investigated transmission of AMR from the environment to humans. Results from Map 1 showed that consumption/ingestion was the most studied transmission route. Exposure (n = 17), infection (n = 16) and colonisation (n = 11) being studied as an outcome a similar number of times, with mortality studied infrequently (n = 2). In addition, E. coli was the most highly studied bacterium (n = 16). For Map 2, we included 62 studies quantifying ARB or resistance elements in the environment in the UK, from 6874 unique articles were identified in the searches. The most highly researched species was mixed communities (n = 32). The most common methodology employed in this research question was phenotypic testing (n = 37). The most commonly reported outcome was the characterisation of ARBs (n = 40), followed by characterisation of ARGs (n = 35). Other genetic elements, such as screening for intI1 (n = 15) (which encodes a Class 1 integron which is used as a proxy for environmental ARGs) and point mutations (n = 1) were less frequently reported. Both maps showed that research was focused towards aquatic environments. Conclusions Both maps can be used by policy makers to show the global (Map 1) and UK (Map 2) research landscapes and provide an overview of the state of AMR in the environment and human health impacts of interacting with the environment. We have also identified (1) clusters of research which may be used to perform meta-analyses and (2) gaps in the evidence base where future primary research should focus.

Background Increasing pressure to publicise research findings and generate impact, alongside an expectation from funding bodies to go beyond publication within academic journals, has generated interest in alternative methods of science communication. Our aim is to describe our experience of using a variety of creative communication tools, reflect on their use in different situations, enhance learning and generate discussion within the systematic review community. Methods Over the last 5 years, we have explored several creative communication tools within the systematic review process and beyond to extend dissemination beyond traditional academic mechanisms. Central to our approach is the co-production of a communication plan with potential evidence users which facilitates (i) the identification of key messages for different audiences, (ii) discussion of appropriate tools to communicate key messages and (iii) exploration of avenues to share them. We aim to involve evidence users in the production of a variety of outputs for each research project cognisant of the many ways in which individuals engage with information. Results Our experience has allowed us to develop an understanding of the benefits and challenges of a wide range of creative communication tools. For example, board games can be a fun way of learning, may flatten power hierarchies between researchers and research users and enable sharing of large amounts of complex information in a thought provoking way, but they are time and resource intensive both to produce and to engage with. Conversely, social media shareable content can be quick and easy to produce and to engage with but limited in the depth and complexity of shareable information. Discussion It is widely recognised that most stakeholders do not have time to invest in reading large, complex documents; creative communication tools can be a used to improve accessibility of key messages. Furthermore, our experience has highlighted a range of additional benefits of embedding these techniques within our project processes e.g. opening up two-way conversations with end-users of research to discuss the implications of findings.

In this review of reviews, we overview the current global body of available evidence from structured reviews of epidemiological studies that explore human health outcomes associated with exposure to phthalates (chemical plasticisers commonly found in plastics). We found robust evidence for an association with lower semen quality, neurodevelopment and risk of childhood asthma, and moderate to robust evidence for impact on anogenital distance in boys. We identified moderate evidence for an association between phthalates/metabolites and low birthweight, endometriosis, decreased testosterone, ADHD, Type 2 diabetes and breast/uterine cancer. There was some evidence for other outcomes including anofourchette distance, fetal sex hormones, pre-term birth, lower antral follicle count, reduced oestrodiol, autism, obesity, thyroid function and hearing disorders. We found no reviews of epidemiological human studies on the impact of phthalates from recycled plastics on human health. We recommend that future research should use urine samples as exposure measures, consider confounders in analyses and measure impacts on female reproductive systems. Our findings align with emerging research indicating that health risks can occur at exposure levels below the “safe dose” levels set out by regulators, and are of particular concern given potential additive or synergistic “cocktail effects” of chemicals. This raises important policy and regulatory issues for identifying and controlling plastics and health related impacts and highlights a need for more research into substances of concern entering plastics waste streams via recycling.

The use of non‐medical referral, community referral or social prescribing interventions has been proposed as a cost‐effective alternative to help those with long‐term conditions manage their illness and improve health and well‐being. However, the evidence base for social prescribing currently lags considerably behind practice. In this paper, we explore what is known about whether different methods of social prescribing referral and supported uptake do (or do not) work. Supported by an Expert Advisory Group, we conducted a realist review in two phases. The first identified evidence specifically relating to social prescribing in order to develop programme theories in the form of ‘if‐then’ statements, articulating how social prescribing models are expected to work. In the second phase, we aimed to clarify these processes and include broader evidence to better explain the proposed mechanisms. The first phase resulted in 109 studies contributing to the synthesis, and the second phase 34. We generated 40 statements relating to organising principles of how the referral takes place (Enrolment), is accepted (Engagement), and completing an activity (Adherence). Six of these statements were prioritised using web‐based nominal group technique by our Expert Group. Studies indicate that patients are more likely to enrol if they believe the social prescription will be of benefit, the referral is presented in an acceptable way that matches their needs and expectations, and concerns elicited and addressed appropriately by the referrer. Patients are more likely to engage if the activity is both accessible and transit to the first session supported. Adherence to activity programmes can be impacted through having an activity leader who is skilled and knowledgeable or through changes in the patient's conditions or symptoms. However, the evidence base is not sufficiently developed methodologically for us to make any general inferences about effectiveness of particular models or approaches.

BACKGROUND: Children and young people with long term physical health conditions are at increased risk of experiencing mental health and wellbeing difficulties. However, there is a lack of research that explores the experiences of, and attitudes towards interventions aiming to improve their mental health and wellbeing. This systematic review seeks to address this gap in the literature by exploring what children and young people with long term conditions, their caregivers and health practitioners perceive to be important aspects of interventions aiming to improve their mental health and wellbeing. // METHODS: An information specialist searched five academic databases using pre-defined criteria for qualitative evaluations of interventions aiming to improve the mental health or wellbeing of children with long term physical conditions. Reviewers also performed supplementary citation and grey literature searches. Two reviewers independently screened titles, abstracts and full texts which met the inclusion criteria and conducted data extraction and quality assessment. Meta-ethnography was used to synthesise the findings. // RESULTS: Screening identified 60 relevant articles. We identified five overarching constructs through the synthesis: i) Getting In and Staying In, ii) Therapeutic Foundation, iii) Social Support, iv) A Hopeful Alternative and v) Empowerment. The line of argument which links these constructs together indicates that when interventions can provide an environment that allows young people to share their experiences and build empathetic relationships; it can enable participants to access social support and increase feelings of hope and empowerment. // CONCLUSION: These findings may provide a framework to inform the development of mental health interventions for this population, and evaluate existing interventions which already include some of the components or processes identified by this research. Further research is needed to establish which of the constructs identified by the line of argument are most effective in improving the mental wellbeing of young people living with long term conditions.

Although mental health difficulties can severely complicate the lives of children and young people (CYP) with long-term physical conditions (LTCs), there is a lack of evidence about the effectiveness of interventions to treat them.To evaluate the clinical effectiveness and cost-effectiveness of interventions aiming to improve the mental health of CYP with LTCs (review 1) and explore the factors that may enhance or limit their delivery (review 2).For review 1, 13 electronic databases were searched, including MEDLINE, EMBASE, PsycINFO, Cochrane Central Register of Controlled Trials (CENTRAL), Cumulative Index to Nursing and Allied Health Literature (CINAHL) and Science Citation Index. For review 2, MEDLINE, PsycINFO and CINAHL were searched. Supplementary searches, author contact and grey literature searches were also conducted.The first systematic review sought randomised controlled trials (RCTs) and economic evaluations of interventions to improve elevated symptoms of mental ill health in CYP with LTCs. Effect sizes for each outcome were calculated post intervention (Cohen'sReview 1 synthesised 25 RCTs evaluating 11 types of intervention, sampling 12 different LTCs. Tentative evidence from seven studies suggests that cognitive-behavioural therapy interventions could improve the mental health of CYP with certain LTCs. Intervention-LTC dyads were diverse, with few opportunities to meta-analyse. No economic evaluations were located. Review 2 synthesised 57 studies evaluating 21 types of intervention. Most studies were of individuals with cancer, a human immunodeficiency virus (HIV) infection or mixed LTCs. Interventions often aimed to improve broader mental health and well-being, rather than symptoms of mental health disorder. The metaethnography identified five main constructs, described in an explanatory line of argument model of the experience of interventions. Nine overarching synthesis categories emerged from the integrated evidence, raising implications for future research.Review 1 conclusions were limited by the lack of evidence about intervention effectiveness. No relevant economic evaluations were located. There were no UK studies included in review 1, limiting the applicability of findings. The mental health status of participants in review 2 was usually unknown, limiting comparability with review 1. The different evidence identified by the two systematic reviews challenged the overarching synthesis.There is a relatively small amount of comparable evidence for the effectiveness of interventions for the mental health of CYP with LTCs. Qualitative evidence provided insight into the experiences that intervention deliverers and recipients valued. Future research should evaluate potentially effective intervention components in high-quality RCTs integrating process evaluations. End-user involvement enriched the project.This study is registered as PROSPERO CRD42011001716.The National Institute for Health Research (NIHR) Health Technology Assessment programme and the NIHR Collaboration for Leadership in Applied Health Research and Care South West Peninsula.Many children and young people with a long-term physical health condition also experience feelings of depression, anxiety and other mental health issues that affect their day-to-day life, their family and others around them. This review investigates whether or not interventions (treatments, strategies and resources) can help children and young people with their mental health. The study also reviewed studies that explored the attitudes and experiences of those involved in receiving or delivering similar interventions. The study found 25 publications that evaluated 11 different types of interventions, including cognitive–behavioural therapy (seven studies) and music therapy (one study). There were some positive effects for the strategies tested on both mental health and other outcomes, but, because the studies were often small, exact effects were uncertain. Many of the studies were not very well designed or carried out and differences between research designs meant that it was hard to compare different studies. The study found 57 publications that explored experiences of interventions. Analysis suggested that it is important that strategies involve building good relationships and are delivered in what feels like a safe space. Participants in studies tended to like interventions that provided social support and helped them feel better about living with a long-term physical condition. Successful interventions were viewed as accessible and engaging. These studies were often conducted well, but they focused on the range of interventions rather than the review evaluating how well interventions work. There are many gaps in the research carried out so far. Some long-term conditions affecting children and young people have not been the subject of studies of mental health interventions, and some important outcomes, such as school attendance and self-care, have not been assessed. More carefully designed UK research consulting children and young people, parents and practitioners is needed before it can be clear what works for children with particular physical conditions to help their mental health, and why.

This handbook is about how Nature on Prescription can be used to support people’s mental health, and makes evidence-based suggestions for how to develop and implement a high-quality scheme, in the new social prescribing landscape. The handbook is primarily aimed at nature-based providers of group nature-based interventions that target common mental health conditions, and that are (or will be) delivered via social prescribing schemes. The content will also be of interest to link workers, general practitioners, mental health practitioners, and researchers with an interest in social prescribing. The content is intended to assist development of interventions that are beneficial, safe, and sustainable. We hope this handbook may: help avoid pitfalls that may lead to Nature on Prescription failing to support people appropriately; make the most of programmes from the earliest stages; help reach desired outcomes for both organisations and participants; and help in designing appropriate evaluations. In this handbook we draw on research evidence and learnings from past and ongoing nature-based interventions, and from other relevant fields. There is a wealth of experience from people who have been involved in delivery of nature-based interventions in the UK. The content of the handbook is also informed by interviews carried out with these individuals and other relevant stakeholders.

Aim: To report on the acceptability of virtual reality (VR) nature environments for people with memory loss at memory cafes, and explore the experiences and perceptions of carers and staff. Methods: A qualitative study was conducted between January and March 2019. Ten adults with memory loss, eight carers and six volunteer staff were recruited from two memory cafes, located in Cornwall, UK. There were 19 VR sessions which were audio recorded and all participants were interviewed at the end of the sessions. Framework analysis was used to identify patterns and themes in the data. Results: During the VR experience, participants were engaged to varying degrees, with engagement facilitated by the researcher, and in some cases, with the help of a carer. Participants responded positively to the nature scenes, finding them soothing and evoking memories. The VR experience was positive, many felt immersed in nature and saw it as an opportunity to ‘go somewhere’. However, it was not always positive and for a few, it could be ‘strange’. Participants reflected on their experience of the VR equipment, and volunteer staff and carers also shared their perceptions of VR for people with dementia in long-term care settings. Conclusions: The VR nature experience was an opportunity for people with memory loss to be immersed in nature and offered the potential to enhance their quality of life. Future work should build on lessons learned and continue to work with people with dementia in developing and implementing VR technology in long-term care settings.

To be effective, the next generation of conservation practitioners and managers need to be critical thinkers with a deep understanding of how to make evidence-based decisions and of the value of evidence synthesis. 2. If, as educators, we do not make these priorities a core part of what we teach, we are failing to prepare our students to make an effective contribution to conservation practice. 3. To help overcome this problem we have created open access online teaching materials in multiple languages that are stored in Applied Ecology Resources. So far, 117 educators from 23 countries have acknowledged the importance of this and are already teaching or about to teach skills in appraising or using evidence in conservation decision-making. This includes 145 undergraduate, postgraduate or professional development courses. 4. We call for wider teaching of the tools and skills that facilitate evidence-based conservation and also suggest that providing online teaching materials in multiple languages could be beneficial for improving global understanding of other subject areas. Making informed conservation and ecosystem management choices is based upon a sound understanding of the relevant evidence. There is an increasing wealth of conservation science available, and access to this is becoming easier. But, are conservation practitioners being trained to utilize this information? In conservation, decision-making is often based upon past experience or expert knowledge, as opposed to the full body of scientific literature (e.g., Pullin, Knight, Stone, & Charman, 2004; Rafidimanantsoa, Poudyal, Ramamonjisoa, & Jones, 2018). The failure to include scientific evidence in decision-making has the potential to reduce the effectiveness of management, or even lead to detrimental actions being undertaken (Walsh, Dicks, & Sutherland, 2015). Evidence-based conservation (EBC) seeks to avoid this by providing tools to facilitate and inform decision-making. To do this, scientific evidence is collated and critically appraised for its quality and relevance, and integrated with other knowledge, experience, values and costs (Sutherland, Pullin, Dolman, & Knight, 2004). Wider adoption of EBC requires conservation professionals to be trained in its principles and taught how to use it to inform conservation decision-making. MAVA Foundation; Arcadia Fund.

Over the last decade, there has been a proliferation of published meta-ethnographies. Yet, strategies and techniques for updating have not received the same attention, rendering answers to important methodological questions still elusive. One such question has to do with who can perform an update. Although it is not uncommon for quantitative systematic reviews and statistical meta-analyses to be updated by different reviewers, qualitative synthesists might find themselves caught between a rock and a hard place. On the one hand, as meta-ethnography constitutes an interpretation three times removed from the lived experience of the participants in the original studies, it could be argued that an update by different reviewers might add an extra layer of interpretation. By comparison, updating by the same reviewers could give rise to concerns about the robustness of updated findings, as an implicit drive for making new data fit the original work might be difficult to control for. We recently reported the findings of our attempt to update an earlier meta-ethnography of primary care antibiotic prescribing, conducted by a different team of reviewers. In this article, we wish to contribute to the emerging debate on the necessity of promoting a culture of updating in qualitative evidence synthesis, by discussing some of the practical and methodological issues we considered at each stage of the process and offering lessons learnt from our experience.

Studies of potential relevance to the objectives of a systematic reviews, as found by the search strategy, should be screened in duplicate for their eligibility. This screening process should be piloted. This protocol provides a step-by-step formula for piloting the screening process of a systematic review. The formula is also applicable to the conduct of systematic evidence maps. There are generally three reasons for piloting the screening process of a systematic review: Are the eligibility criteria expressed clearly enough? Are the screeners on the review team interpreting the criteria consistently? Are there papers which should be included in the review but had not been anticipated as being relevant? This protocol presents a process for answering each of these questions in the affirmative and preparing to ensure that the screening step of the systematic review is a success, i.e. it does not result in exclusion of evidence which is relevant to the research question.

Background Encouraging incidental physical activity is an important strategy to improve population health. Recent research has drawn on social practice theory to describe the recursive and relational character of active living, which could help to understand conditions for change. A growing evidence base suggests that gender should be considered amongst these conditions as an independent influence on travel behaviour, and qualitative studies have been particularly valuable to understand differential experiences. Our aim was to upscale insights from individual contexts, by synthesising data from primary qualitative research studies, to explore gendered patterns within active travel practices. Methods We pooled 280 transcripts from five research projects conducted in the UK, including a range of populations, travel modes and settings. All data included gender descriptors, but most studies did not set out to study gender specifically. Text analytics software, Leximancer, was used in the first phase of the analysis to produce inter-topic distance maps to illustrate inter-related ‘concepts’. These maps guided a second researcher-led interpretive analysis of text excerpts to infer meaning from the computer-generated outputs, whilst maintaining sight of the explanatory strength of qualitative data and its social theoretical framing or original context. Results Our interpretative findings indicate gender differentiated experiences and travel narratives. Firstly, focusing particularly on respondents’ commutes (travelling to and from work), and guided by social practice theory, we identified ‘interrelated’ and ‘relating’ practices across the pooled datasets. Women largely spoke about how their journeys associated with their commute were ‘bundled together’ as a series of multifunctional trips that included the school run or shopping, whereas men described relatively linear journeys from A to B but highlighted ‘relating’ practices to their journeys, such as showering after cycling to work. Secondly, we identified a gendered difference in the way men and women spoke about travel practices across contexts, particularly with reference to safety or danger. Women spoke more about themselves as actors in travel, how they are identified and their internal feelings of safety (‘I feel unsafe’), and men’s talk was more outwardly framed, and in terms of danger spoke about external conditions (‘it is a dangerous road’). Conclusion Our research highlights gender differential experiences and accounts of travel experience. These findings can inform future research and policy decisions that aim to promote healthier travel practices, by emphasising the need to consider how gender (and other social positions) might shape practices and accounts of those practices.

Background Antimicrobial resistance (AMR) is a public health crisis that is predicted to cause 10 million deaths per year by 2050. The environment has been implicated as a reservoir of AMR and is suggested to play a role in the dissemination of antibiotic resistance genes (ARGs). Currently, most research has focused on measuring concentrations of antibiotics and characterising the abundance and diversity of ARGs and antibiotic resistant bacteria (ARB) in the environment. To date, there has been limited empirical research on whether humans are exposed to this, and whether exposure can lead to measureable impacts on human health. Therefore, the objective of this work is to produce two linked systematic maps to investigate previous research on exposure and transmission of AMR to humans from the environment. The first map will investigate the available research relating to exposure and transmission of ARB/ARGs from the environment to humans on a global scale and the second will investigate the prevalence of ARB/ARGs in various environments in the UK. These two maps will be useful for policy makers and research funders to identify where there are significant gluts and gaps in the current research, and where more primary and synthesis research needs to be undertaken. Methods Separate search strategies will be developed for the two maps. Searches will be run in 13 databases, and grey literature will be sought from key websites and engagement with experts. Hits will be managed in EndNote and screened in two stages (title/abstract then full text) against predefined inclusion criteria. A minimum of 10% will be double screened with ongoing consistency checking. All included studies will have data extracted into a bespoke form designed and piloted for each map. Data to be extracted will include bibliographic details, study design, location, exposure source, exposure route, health outcome (Map 1); and prevalence/percentage of ARB/ARG (Map 2). No validity appraisal will be undertaken. Results will be tabulated and presented narratively, together with graphics showing the types and areas of research that has been undertaken and heatmaps for key exposure-health outcomes (Map 1) and exposure-prevalence (Map 2).

Background Globally, there is increasing scientific evidence of critical links between the oceans and human health, with research into issues such as pollution, harmful algal blooms and nutritional contributions. However, Oceans and Human Health (OHH) remains an emerging discipline. As such these links are poorly recognized in policy efforts such as the Sustainable Development Goals, with OHH not included in either marine (SDG14) or health (SDG3) goals. This is arguably short-sighted given recent development strategies such as the EU Blue Growth Agenda. Objectives In this systematic map we aim to build on recent efforts to enhance OHH in Europe by setting a baseline of existing evidence, asking: What links have been researched between marine environments and the positive and negative impacts to human health and wellbeing? Methods We searched eight bibliographic databases and queried 57 organizations identified through stakeholder consultation. Results include primary research and systematic reviews which were screened double blind against pre-defined inclusion criteria as per a published protocol. Studies were limited to Europe, US, Australia, New Zealand and Canada. Data was extracted according to a stakeholder-defined code book. A narrative synthesis explores the current evidence for relationships between marine exposures and human health outcomes, trends in knowledge gaps and change over time in the OHH research landscape. The resulting database is available on the website of the Seas, Oceans and Public Health in Europe website ( https://sophie2020.eu/ ). Results A total of 1,542 unique articles were included in the database, including those examined within 56 systematic reviews. Research was dominated by a US focus representing 50.1% of articles. A high number of articles were found to link: marine biotechnology and cardiovascular or immune conditions, consumption of seafood and cardiovascular health, chemical pollution and neurological conditions, microbial pollution and gastrointestinal or respiratory health, and oil industry occupations with mental health. A lack of evidence relates to direct impacts of plastic pollution and work within a number of industries identified as relevant by stakeholders. Research over time is dominated by marine biotechnology, though this is narrow in focus. Pollution, food and disease/injury research follow similar trajectories. Wellbeing and climate change have emerged more recently as key topics but lag behind other categories in volume of evidence. Conclusions The evidence base for OHH of relevance to European policy is growing but remains patchy and poorly co-ordinated. Considerable scope for future evidence synthesis exists to better inform policy-makers, though reviews need to better incorporate complex exposures. Priorities for future research include: proactive assessments of chemical pollutants, measurable impacts arising from climate change, effects of emerging marine industries, and regional and global assessments for OHH interactions. Understanding of synergistic effects across multiple exposures and outcomes using systems approaches is recommended to guide policies within the Blue Growth Strategy. Co-ordination of research across Europe and dedicated centres of research would be effective first steps.

Progress towards effective conservation requires understanding mechanisms for achieving impact within complex social-ecological systems. Causal models are useful tools for defining plausible pathways from conservation actions to impacts on nature and people. Evaluating the potential of different strategies for delivering co-benefits for nature and people will require the use and testing of clear causal models that explicitly define the logic and assumptions behind cause and effect relationships. Objectives and methods: In this study, we outline criteria for credible causal models and systematically evaluated their use in a broad base of literature (~1,000 peer-reviewed and grey literature articles from a published systematic evidence map) on links between nature-based conservation actions and human well-being impacts. Results: Out of 1,027 publications identified, only ~20% of articles used any type of causal models to guide their work, and only 14 total articles fulfilled all criteria for credibility. Articles rarely tested the validity of models with empirical data. Implications: Not using causal models risks poorly defined strategies, misunderstanding of potential mechanisms for affecting change, inefficient use of resources, and focusing on implausible efforts for achieving sustainability.

Background Innovative approaches are required to move beyond individual approaches to behaviour change and develop more appropriate insights for the complex challenge of increasing population levels of activity. Recent research has drawn on social practice theory to describe the recursive and relational character of active living but to date most evidence is limited to small-scale qualitative research studies. To ‘upscale’ insights from individual contexts, we pooled data from five qualitative studies and used machine learning software to explore gendered patterns in the context of active travel. Methods We drew on 280 transcripts from five research projects conducted in the UK, including studies of a range of populations, travel modes and settings, to conduct unsupervised ‘topic modelling analysis’. Text analytics software, Leximancer, was used in the first phase of the analysis to produce inter-topic distance maps to illustrate inter-related ‘concepts’. The outputs from this first phase guided a second researcher-led interpretive analysis of text excerpts to infer meaning from the computer-generated outputs. Results Guided by social practice theory, we identified ‘interrelated’ and ‘relating’ practices across the pooled datasets. For this study we particularly focused on respondents’ commutes, travelling to and from work, and on differentiated experiences by gender. Women largely described their commute as multifunctional journeys that included the school run or shopping, whereas men described relatively linear journeys from A to B but highlighted ‘relating’ practices resulting from or due to their choice of commute mode or journey such as showering or relaxing. Secondly, we identify a difference in discourses about practices across the included datasets. Women spoke more about ‘subjective’, internal feelings of safety (‘I feel unsafe’), whereas men spoke more about external conditions (‘it is a dangerous road’). Conclusion This rare application of machine learning to qualitative social science research has helped to identify potentially important differences in co-occurrence of practices and discourses about practice between men’s and women’s accounts of travel across diverse contexts. These findings can inform future research and policy decisions for promoting travel-related social practices associated with increased physical activity that are appropriate across genders.

This study aimed to address the question: what does "effectiveness" mean to researchers in the context of literature searching for systematic reviews? We conducted a thematic analysis of responses to an e-mail survey. Eighty-nine study authors, whose studies met inclusion in a recent review (2018), were contacted via e-mail and asked three questions; one directly asking the question: in literature searching, what does effective (or effectiveness in) literature searching mean to you? Thirty-eight (46%) responses were received from diverse professional groups, including: literature searchers, systematic reviewers, clinicians and researchers. A shared understanding of what effectiveness means was not identified. Instead, five themes were developed from data: (a) effectiveness is described as a metric; (b) effectiveness is a balance between metrics; (c) effectiveness can be categorized by search purpose; (d) effectiveness is an outcome; and, (e) effectiveness is an experimental concept. We propose that these themes constitute a preliminary typology of understandings. No single definition of effectiveness was identified. The proposed typology suggests that different researchers have differing understandings of effectiveness. This could lead to uncertainty as to the aim and the purpose of literature searches and confusion about the outcomes. The typology offers a potential route for further exploration.

Background Systematic literature searching is recognised as a critical component of the systematic review process. It involves a systematic search for studies and aims for a transparent report of study identification, leaving readers clear about what was done to identify studies, and how the findings of the review are situated in the relevant evidence. Information specialists and review teams appear to work from a shared and tacit model of the literature search process. How this tacit model has developed and evolved is unclear, and it has not been explicitly examined before. The purpose of this review is to determine if a shared model of the literature searching process can be detected across systematic review guidance documents and, if so, how this process is reported in the guidance and supported by published studies. Method A literature review. Two types of literature were reviewed: guidance and published studies. Nine guidance documents were identified, including: The Cochrane and Campbell Handbooks. Published studies were identified through ‘pearl growing’, citation chasing, a search of PubMed using the systematic review methods filter, and the authors’ topic knowledge. The relevant sections within each guidance document were then read and re-read, with the aim of determining key methodological stages. Methodological stages were identified and defined. This data was reviewed to identify agreements and areas of unique guidance between guidance documents. Consensus across multiple guidance documents was used to inform selection of ‘key stages’ in the process of literature searching. Results Eight key stages were determined relating specifically to literature searching in systematic reviews. They were: who should literature search, aims and purpose of literature searching, preparation, the search strategy, searching databases, supplementary searching, managing references and reporting the search process. Conclusions Eight key stages to the process of literature searching in systematic reviews were identified. These key stages are consistently reported in the nine guidance documents, suggesting consensus on the key stages of literature searching, and therefore the process of literature searching as a whole, in systematic reviews. Further research to determine the suitability of using the same process of literature searching for all types of systematic review is indicated.

The Cochrane Qualitative and Implementation Methods Group develops and publishes guidance on the synthesis of qualitative and mixed-method evidence from process evaluations. Despite a proliferation of methods for the synthesis of qualitative research, less attention has focused on how to integrate these syntheses within intervention effectiveness reviews. In this article, we report updated guidance from the group on approaches, methods, and tools, which can be used to integrate the findings from quantitative studies evaluating intervention effectiveness with those from qualitative studies and process evaluations. We draw on conceptual analyses of mixed methods systematic review designs and the range of methods and tools that have been used in published reviews that have successfully integrated different types of evidence. We outline five key methods and tools as devices for integration which vary in terms of the levels at which integration takes place; the specialist skills and expertise required within the review team; and their appropriateness in the context of limited evidence. In situations where the requirement is the integration of qualitative and process evidence within intervention effectiveness reviews, we recommend the use of a sequential approach. Here, evidence from each tradition is synthesized separately using methods consistent with each tradition before integration takes place using a common framework. Reviews which integrate qualitative and process evaluation evidence alongside quantitative evidence on intervention effectiveness in a systematic way are rare. This guidance aims to support review teams to achieve integration and we encourage further development through reflection and formal testing. Refereed/Peer-reviewed

Background: Antibiotic-resistant bacteria (ARB) present a global public health problem. With numbers of community-acquired resistant infections increasing, understanding the mechanisms by which people are exposed to and colonised by ARB can help inform effective strategies to prevent their spread. The role natural environments play in this is poorly understood. This is the first study to combine surveillance of ARB in bathing waters, human exposure estimates and association between exposure and colonisation by ARB in water users. Methods: 97 bathing water samples from England and Wales were analysed for the proportion of E. coli harbouring blaCTX-M. These data were used to estimate the likelihood of water users ingesting blaCTX-M-bearing E. coli. Having identified surfers as being at risk of exposure to ARB, a cross-sectional study was conducted. Regular surfers and non-surfers were recruited to assess whether there is an association between surfing and gut colonisation by blaCTX-M-bearing E. coli. Results: 11 of 97 bathing waters sampled were found to contain blaCTX-M-bearing E. coli. While the percentage of blaCTX-M-bearing E. coli in bathing waters was low (0.07%), water users are at risk of ingesting these ARB. It is estimated that over 2.5 million water sports sessions occurred in 2015 resulting in the ingestion of at least one blaCTX-M-bearing E. coli. In the epidemiological survey, 9/143 (6.3%) surfers were colonised by blaCTX-M-bearing E. coli, as compared to 2/130 (1.5%) of non-surfers (risk ratio=4.09, 95% CI 1.02 to 16.4, p=0.046). Conclusions: Surfers are at risk of exposure to and colonisation by clinically important antibiotic-resistant E. coli in coastal waters. Further research must be done on the role natural environments play in the transmission of ARB. Keywords: Antibiotic resistant bacteria, Coastal waters, Surfers, Escherichia coli, CTX-M

Background Every year, more than 800,000 people worldwide die by suicide. The aim of this study was to conduct a systematic review of the effectiveness of brief psychological interventions in addressing suicidal thoughts and behaviour in healthcare settings. Methods Following PRISMA guidelines, systematic searches were conducted in MEDLINE, CINAHL, EMBASE, the Cochrane Central Register of Controlled Trials and PsycINFO databases. A predefined search strategy was used. Two independent reviewers screened titles and abstracts followed by full texts against predefined inclusion criteria. Backward and forward citation tracking of included papers was conducted. Quality appraisal was conducted using the Cochrane Risk of Bias Tool for Randomized Controlled Trials and the CASP tool for randomised controlled trials. The small number and heterogeneity of studies did not allow for meta-analysis to be conducted. A narrative synthesis was conducted. Results Four controlled studies of brief psychological interventions were included, conducted in Switzerland, the U.S. and across low and middle-income countries. Three studies were conducted with adults and one with adolescents. All studies were judged to be at low risk of bias. All of the interventions were implemented with patients after attending emergency departments and involved 3412 participants. The main outcomes were suicide, suicide attempts, suicidal ideation, depression and hospitalization. The components of the interventions were early therapeutic engagement, information provision, safety planning and follow-up contact for at least 12 months. The interventions drew to, different degrees, on psychological theory and techniques. Two trials that measured suicidal ideation found no impact. Two studies showed fewer suicide attempts, one showed fewer suicides and one found an effect on depression. Conclusions Although the evidence base is small, brief psychological interventions appear to be effective in reducing suicide and suicide attempts. All studies to date have been conducted with people who had attended the ED but the interventions could potentially be adopted for inpatient and other outpatient settings. Early engagement and therapeutic intervention based on psychological theories of suicidal behaviour, sustained in follow-up contacts, may be particularly beneficial.

Objectives: This article provides reviewers with guidance on methods for identifying and processing evidence to understand intervention implementation. Study Design and Setting: Strategies, tools, and methods are applied to the systematic review process to illustrate how process and implementation can be addressed using quantitative, qualitative, and other sources of evidence (i.e., descriptive textual and nonempirical). Results: Reviewers can take steps to navigate the heterogeneity and level of uncertainty present in the concepts, measures, and methods used to assess implementation. Activities can be undertaken in advance of a Cochrane quantitative review to develop program theory and logic models that situate implementation in the causal chain. Four search strategies are offered to retrieve process and implementation evidence. Recommendations are made for addressing rigor or risk of bias in process evaluation or implementation evidence. Strategies are recommended for locating and extracting data from primary studies. The basic logic is presented to assist reviewers to make initial review-level judgments about implementation failure and theory failure. Conclusion: Although strategies, tools, and methods can assist reviewers to address process and implementation using quantitative, qualitative, and other forms of evidence, few exemplar reviews exist. There is a need for further methodological development and trialing of proposed approaches. Refereed/Peer-reviewed

Background Conservation activities and natural resource management interventions have often aimed to tackle the dual challenge of improving nature conservation and human well-being. However, there is concern over the extent to which this dual goal has been achieved, and an increasing recognition of trade-offs and synergies within and between aspects of each of the goals. The amount and scope of the available evidence on the success of conservation and management interventions in both arenas has lacked documentation, for a number of reasons, including limited resources for monitoring and evaluation and the difficulty in bringing together a disparate evidence base. This systematic map focuses on the interaction between marine conservation management and the health and well-being of coastal communities in South East Asia. Method We searched bibliographic databases to find published literature, and identified grey literature through institutional and organisational website searches and key stakeholders. Eligibility criteria were applied in two stages, title and abstract and full text, with consistency checks. We extracted meta-data on the design and characteristics of each study, from which we produced an interactive database and map, and a narrative summary. Results We assessed 42,894 records at title and abstract from the main searches. 1,331 articles were assessed at full text (30 articles were not retrievable). 287 articles (281 studies) were included in the systematic map. Most studies were peer-reviewed publications (90%), and from the Philippines and Indonesia (72%). 31% of studies were solely qualitative, 45% were solely quantitative and 24% included both qualitative and quantitative research. Only 24% (31/127) of quantitative studies included a comparator. We identified knowledge clusters where studies investigated the links between the marine conservation interventions: Site Protection, Economic or Livelihood Incentives or Alternatives, or Habitat Management, and the human health and well-being outcomes: Economic Living Standards, Governance and Empowerment, or Social Relations. In addition, qualitative research clusters were identified exploring the links between the intervention Habitat Management, and the outcome Governance and Empowerment, and between the intervention Economic or Livelihood Incentives or Alternatives, and the outcomes of Governance and Empowerment, and Social Relations. We identified major knowledge gaps in evidence for the effect of marine conservation interventions on the outcomes Freedom of Choice and Action, Security and Safety, Subjective Well-being, Health, and Culture and Spirituality. There was a lack of studies involving Education, Awareness and Activism interventions that reported any human health and well-being outcomes. Conclusion We present the first updatable, interrogable and comprehensive evidence map on this topic for South East Asia. Our work supports further, detailed investigation of knowledge clusters using systematic review and also serves to identify understudied topic areas. The lack of comparative, quantitative studies suggests that future research should include counterfactuals to strengthen the robustness of evidence base. Users of this systematic map should recognise that much evidence may be national or locally specific, and that we did not undertake an assessment of study quality. Thus, when considering implications for policy and decision-making, users should carefully consider the heterogeneity of available evidence and refer to original research articles to gain a full depth of understanding and context.

Important policy questions tend to span a range of academic disciplines, and the relevant research is often carried out in a variety of social, economic and geographic contexts. In efforts to synthesise research to help inform decisions arising from the policy questions, systematic reviews need conceptual frameworks and ways of thinking that combine knowledge drawn from different academic traditions and contexts; in other words, transdisciplinary research. This paper considers how transdisciplinary working can be achieved with: conceptual frameworks that span traditional academic boundaries; methods for shaping review questions and conceptual frameworks; and methods for interpreting the relevance of findings to different contexts. It also discusses the practical challenges and ultimate benefits of transdisciplinary working for systematic reviews.

We continue the conversation initiated by Sally Thorne’s observations about “metasynthetic madness.” We note that the variety of labels used to describe qualitative syntheses often reflect authors’ disciplines and geographical locations. The purpose of systematic literature searching is to redress authors’ lack of citation of relevant earlier work and to reassure policy makers that qualitative syntheses are systematic and transparent. There is clearly a need to develop other methods of searching to supplement electronic searches. If searches produce large numbers of articles, sampling strategies may be needed to choose which articles to synthesize. The quality of any synthesis is dependent on the quality of the primary articles; both primary research and qualitative synthesis need to move beyond description and toward theory and explanation. Synthesizers need to pay attention to those articles which do not seem to fit their emerging analysis if they are to avoid stifling new ideas.

Behaviour change interventions can be effective in helping people to lose weight, but weight is often regained. Effective interventions are required to prevent this. We conducted a systematic review and synthesis of qualitative research on people's experiences of weight loss maintenance. We searched bibliographic databases for qualitative studies about the experience of currently or previously overweight adults trying to maintain weight loss. We thematically synthesised study findings to develop a model of weight loss maintenance. Twenty six studies from five countries with 710 participants were included. The model developed through our synthesis proposes that making the behaviour changes required for weight loss maintenance generates psychological 'tension' due to the need to override existing habits, and incompatibility of the new behaviours with the fulfilment of psychological needs. Successful maintenance involves management or resolution of this tension. Management of tension can be achieved through self-regulation, renewing of motivation and managing external influences, although this can require constant effort. Resolution may be achieved through changing habits, finding non-obesogenic methods for addressing needs, and potentially through change in self-concept. Implications for the development of weight loss maintenance interventions are explored.

The risks of illness associated with bathing in UK coastal waters have not been quantified since the early 1990s. Efforts have been made since then to improve the quality of bathing waters. The aim of this study was to quantify the prevalence of symptoms of illness associated with sea bathing in bathers in England and Wales. A cross-sectional study was conducted between June 2014 and April 2015. An online survey collected information from sea bathers and non-bathers on their visits to beaches in England and Wales along with the occurrence of symptoms of illness. 2631 people (1693 bathers, 938 non-bathers) responded to the survey. Compared to non-bathers, bathers were more likely to report skin ailments (adjusted prevalence odds ratio (AOR) = 2.64, 95% confidence interval (CI) 1.23 to 5.65, p = 0.01), ear ailments (AOR = 3.77, 95% CI 1.84 to 7.73, p

Background Robopets are small animal-like robots which have the appearance and behavioural characteristics of pets. Objective To bring together the evidence of the experiences of staff, residents and family members of interacting with robopets and the effects of robopets on the health and well-being of older people living in care homes. Design Systematic review of qualitative and quantitative research. Data sources We searched 13 electronic databases from inception to July 2018 and undertook forward and backward citation chasing. Methods Eligible studies reported the views and experiences of robopets from residents, family members and staff (qualitative studies using recognised methods of qualitative data collection and analysis) and the effects of robopets on the health and well-being of care home residents (randomised controlled trials, randomised crossover trials and cluster randomised trials). Study selection was undertaken independently by two reviewers. We used the Wallace criteria and the Cochrane Risk of Bias tool to assess the quality of the evidence. We developed a logic model with stakeholders and used this as a framework to guide data extraction and synthesis. Where appropriate, we used meta-analysis to combine effect estimates from quantitative studies. Results Nineteen studies (10 qualitative, 2 mixed methods and 7 randomised trials) met the inclusion criteria. Interactions with robopets were described as having a positive impact on aspects of well-being including loneliness, depression and quality of life by residents and staff, although there was no corresponding statistically significant evidence from meta-analysis for these outcomes. Meta-analysis showed evidence of a reduction in agitation with the robopet "Paro" compared to control (-0.32 [95% CI -0.61 to -0.04, p = 0.03]). Not everyone had a positive experience of robopets. Conclusions Engagement with robopets appears to have beneficial effects on the health and well-being of older adults living in care homes, but not all chose to engage. Whether the benefits can be sustained are yet to be investigated. Implications for practice Robopets have the potential to benefit people living in care homes, through increasing engagement and interaction. With the robopet acting as a catalyst, this engagement and interaction may afford comfort and help reduce agitation and loneliness.

Involving and engaging the public are crucial for effective prioritisation, dissemination and implementation of research about the complex interactions between environments and health. Involvement is also important to funders and policy makers who often see it as vital for building trust and justifying the investment of public money. In public health research, ‘the public’ can seem an amorphous target for researchers to engage with, and the short-term nature of research projects can be a challenge. Technocratic and pedagogical approaches have frequently met with resistance, so public involvement needs to be seen in the context of a history which includes contested truths, power inequalities and political activism. It is therefore vital for researchers and policy makers, as well as public contributors, to share best practice and to explore the challenges encountered in public involvement and engagement. This article presents a theoretically informed case study of the contributions made by the Health and Environment Public Engagement Group to the work of the National Institute for Health Research (NIHR) Health Protection Research Unit in Environmental Change and Health (HPRU-ECH). We describe how Health and Environment Public Engagement Group has provided researchers in the HPRU-ECH with a vehicle to support access to public views on multiple aspects of the research work across three workshops, discussion of ongoing research issues at meetings and supporting dissemination to local government partners, as well as public representation on the HPRU-ECH Advisory Board. We conclude that institutional support for standing public involvement groups can provide conduits for connecting public with policy makers and academic institutions. This can enable public involvement and engagement, which would be difficult, if not impossible, to achieve in individual short-term and unconnected research projects.

This paper is one of a series exploring the implications of complexity for systematic reviews and guideline development, commissioned by the WHO. The paper specifically explores the role of qualitative evidence synthesis. Qualitative evidence synthesis is the broad term for the group of methods used to undertake systematic reviews of qualitative research evidence. As an approach, qualitative evidence synthesis is increasingly recognised as having a key role to play in addressing questions relating to intervention or system complexity, and guideline development processes. This is due to the unique role qualitative research can play in establishing the relative importance of outcomes, the acceptability, fidelity and reach of interventions, their feasibility in different settings and potential consequences on equity across populations. This paper outlines the purpose of qualitative evidence synthesis, provides detail of how qualitative evidence syntheses can help establish understanding and explanation of the complexity that can occur in relation to both interventions and systems, and how qualitative evidence syntheses can contribute to evidence to decision frameworks. It provides guidance for the choice of qualitative evidence synthesis methods in the context of guideline development for complex interventions, giving ‘real life’ examples of where this has occurred. Information to support decision-making around choice qualitative evidence synthesis methods in the context of guideline development is provided. Approaches for reporting qualitative evidence syntheses are discussed alongside mechanisms for assessing confidence in the findings of a review.

Systematic review teams and guideline development groups face considerable challenges when considering context within the evidence production process. Many complex interventions are context-dependent and are frequently evaluated within considerable contextual variation and change. This paper considers the extent to which current tools used within systematic reviews and guideline development are suitable in meeting these challenges. The paper briefly reviews strengths and weaknesses of existing approaches to specifying context. Illustrative tools are mapped to corresponding stages of the systematic review process. Collectively, systematic review and guideline production reveals a rich diversity of frameworks and tools for handling context. However, current approaches address only specific elements of context, are derived from primary studies which lack information or have not been tested within systematic reviews. A hypothetical example is used to illustrate how context could be integrated throughout the guideline development process. Guideline developers and evidence synthesis organisations should select an appropriate level of contextual detail for their specific guideline that is parsimonious and yet sensitive to health systems contexts and the values, preferences and needs of their target populations.
