What do we know about demand, use and outcomes in primary care out-of-hours services? A systematic scoping review of international literature.

OBJECTIVE: To synthesise international evidence for demand, use and outcomes of primary care out-of-hours health services (OOHS). DESIGN: Systematic scoping review. DATA SOURCES: CINAHL; Medline; PsyARTICLES; PsycINFO; SocINDEX; and Embase from 1995 to 2019. STUDY SELECTION: English language studies in UK or similar international settings, focused on services in or directly impacting primary care. RESULTS: 105 studies included: 54% from mainland Europe/Republic of Ireland; 37% from UK. Most focused on general practitioner-led out-of-hours cooperatives. Evidence for increasing patient demand over time was weak due to data heterogeneity, infrequent reporting of population denominators and little adjustment for population sociodemographics. There was consistent evidence of higher OOHS use in the evening compared with overnight, at weekends and by certain groups (children aged <5, adults aged >65, women, those from socioeconomically deprived areas, with chronic diseases or mental health problems). Contact with OOHS was driven by problems perceived as urgent by patients. Respiratory, musculoskeletal, skin and abdominal symptoms were the most common reasons for contact in adults; fever and gastrointestinal symptoms were the most common in the under-5s. Frequent users of daytime services were also frequent OOHS users; difficulty accessing daytime services was also associated with OOHS use. There is some evidence to suggest that OOHS colocated in emergency departments (ED) can reduce demand in EDs. CONCLUSIONS: Policy changes have impacted on OOHS over the past two decades. While there are generalisable lessons, a lack of comparable data makes it difficult to judge how demand has changed over time. Agreement on collection of OOHS data would allow robust comparisons within and across countries and across new models of care. Future developments in OOHS should also pay more attention to the relationship with daytime primary care and other services. PROSPERO REGISTRATION NUMBER: CRD42015029741.

Staphylococcus aureus infection dynamics.

Staphylococcus aureus is a human commensal that can also cause systemic infections. This transition requires evasion of the immune response and the ability to exploit different niches within the host. However, the disease mechanisms and the dominant immune mediators against infection are poorly understood. Previously it has been shown that the infecting S. aureus population goes through a population bottleneck, from which very few bacteria escape to establish the abscesses that are characteristic of many infections. Here we examine the host factors underlying the population bottleneck and subsequent clonal expansion in S. aureus infection models, to identify underpinning principles of infection. The bottleneck is a common feature between models and is independent of S. aureus strain. Interestingly, the high doses of S. aureus required for the widely used "survival" model results in a reduced population bottleneck, suggesting that host defences have been simply overloaded. This brings into question the applicability of the survival model. Depletion of immune mediators revealed key breakpoints and the dynamics of systemic infection. Loss of macrophages, including the liver Kupffer cells, led to increased sensitivity to infection as expected but also loss of the population bottleneck and the spread to other organs still occurred. Conversely, neutrophil depletion led to greater susceptibility to disease but with a concomitant maintenance of the bottleneck and lack of systemic spread. We also used a novel microscopy approach to examine abscess architecture and distribution within organs. From these observations we developed a conceptual model for S. aureus disease from initial infection to mature abscess. This work highlights the need to understand the complexities of the infectious process to be able to assign functions for host and bacterial components, and why S. aureus disease requires a seemingly high infectious dose and how interventions such as a vaccine may be more rationally developed.

Material practices for meaningful engagement: An analysis of participatory learning and action research techniques for data generation and analysis in a health research partnership.

BACKGROUND: The material practices which researchers use in research partnerships may enable or constrain the nature of engagement with stakeholder groups. Participatory learning and action (PLA) research approaches show promise, but there has been no detailed analysis of stakeholders' and researchers' experiences of PLA techniques for data generation and co-analysis. OBJECTIVES: To explore stakeholders' and researchers' experiences of PLA techniques for data generation and co-analysis. DESIGN: The EU RESTORE implementation science project employed a participatory approach to investigate and support the implementation of guidelines and training initiatives (GTIs) to enhance communication in cross-cultural primary care consultations. We developed a purposeful sample of 78 stakeholders (migrants, general practice staff, community interpreters, service providers, service planners) from primary care settings in Austria, England, Greece, Ireland and The Netherlands. We used speed evaluations and participatory evaluations to explore their experiences of two PLA techniques-Commentary Charts and Direct Ranking-which were intended to generate data for co-analysis by stakeholders about the GTIs under analysis. We evaluated 16 RESTORE researchers' experiences using interviews. We conducted thematic and content analysis of all evaluation data. RESULTS: PLA Commentary Charts and Direct Ranking techniques, with their visual, verbal and tangible nature and inherent analytical capabilities, were found to be powerful tools for involving stakeholders in a collaborative analysis of GTIs. Stakeholders had few negative experiences and numerous multifaceted positive experiences of meaningful engagement, which resonated with researchers' accounts. CONCLUSION: PLA techniques and approaches are valuable as material practices in health research partnerships.

Supporting the use of theory in cross-country health services research: a participatory qualitative approach using Normalisation Process Theory as an example.

OBJECTIVES: To describe and reflect on the process of designing and delivering a training programme supporting the use of theory, in this case Normalisation Process Theory (NPT), in a multisite cross-country health services research study. DESIGN: Participatory research approach using qualitative methods. SETTING: Six European primary care settings involving research teams from Austria, England, Greece, Ireland, The Netherlands and Scotland. PARTICIPANTS: RESTORE research team consisting of 8 project applicants, all senior primary care academics, and 10 researchers. Professional backgrounds included general practitioners/family doctors, social/cultural anthropologists, sociologists and health services/primary care researchers. PRIMARY OUTCOME MEASURES: Views of all research team members (n=18) were assessed using qualitative evaluation methods, analysed qualitatively by the trainers after each session. RESULTS: Most of the team had no experience of using NPT and many had not applied theory to prospective, qualitative research projects. Early training proved didactic and overloaded participants with information. Drawing on RESTORE's methodological approach of Participatory Learning and Action, workshops using role play, experiential interactive exercises and light-hearted examples not directly related to the study subject matter were developed. Evaluation showed the study team quickly grew in knowledge and confidence in applying theory to fieldwork.Recommendations applicable to other studies include: accepting that theory application is not a linear process, that time is needed to address researcher concerns with the process, and that experiential, interactive learning is a key device in building conceptual and practical knowledge. An unanticipated benefit was the smooth transition to cross-country qualitative coding of study data. CONCLUSION: A structured programme of training enhanced and supported the prospective application of a theory, NPT, to our work but raised challenges. These were not unique to NPT but could arise with the application of any theory, especially in large multisite, international projects. The lessons learnt are applicable to other theoretically informed studies.

Exploring barriers to primary care for migrants in Greece in times of austerity: Perspectives of service providers.

BACKGROUND: Migration in Europe is increasing at an unprecedented rate. There is an urgent need to develop 'migrant-sensitive healthcare systems'. However, there are many barriers to healthcare for migrants. Despite Greece's recent, significant experiences of inward migration during a period of economic austerity, little is known about Greek primary care service providers' experiences of delivering care to migrants. OBJECTIVES: To identify service providers' views on the barriers to migrant healthcare. METHODS: Qualitative study involving six participatory learning and action (PLA) focus group sessions with nine service providers. Data generation was informed by normalization process theory (NPT). Thematic analysis was applied to identify barriers to efficient migrant healthcare. RESULTS: Three main provider and system-related barriers emerged: (a) emphasis on major challenges in healthcare provision, (b) low perceived control and effectiveness to support migrant healthcare, and (c) attention to impoverished local population. CONCLUSION: The study identified major provider and system-related barriers in the provision of primary healthcare to migrants. It is important for the healthcare system in Greece to provide appropriate supports for communication in cross-cultural consultations for its diversifying population.

Engaging migrants and other stakeholders to improve communication in cross-cultural consultation in primary care: a theoretically informed participatory study.

OBJECTIVES: Guidelines and training initiatives (G/TIs) are available to support communication in cross-cultural consultations but are rarely implemented in routine practice in primary care. As part of the European Union RESTORE project, our objective was to explore whether the available G/TIs make sense to migrants and other key stakeholders and whether they could collectively choose G/TIs and engage in their implementation in primary care settings. SETTING: As part of a comparative analysis of 5 linked qualitative case studies, we used purposeful and snowball sampling to recruit migrants and other key stakeholders in primary care settings in Austria, England, Greece, Ireland and the Netherlands. PARTICIPANTS: A total of 78 stakeholders participated in the study (Austria 15, England 9, Ireland 11, Greece 16, Netherlands 27), covering a range of groups (migrants, general practitioners, nurses, administrative staff, interpreters, health service planners). PRIMARY AND SECONDARY OUTCOME MEASURES: We combined Normalisation Process Theory (NPT) and Participatory Learning and Action (PLA) research to conduct a series of PLA style focus groups. Using a standardised protocol, stakeholders' discussions about a set of G/TIs were recorded on PLA commentary charts and their selection process was recorded through a PLA direct-ranking technique. We performed inductive and deductive thematic analysis to investigate sensemaking and engagement with the G/TIs. RESULTS: The need for new ways of working was strongly endorsed by most stakeholders. Stakeholders considered that they were the right people to drive the work forward and were keen to enrol others to support the implementation work. This was evidenced by the democratic selection by stakeholders in each setting of one G/TI as a local implementation project. CONCLUSIONS: This theoretically informed participatory approach used across 5 countries with diverse healthcare systems could be used in other settings to establish positive conditions for the start of implementation journeys for G/TIs to improve healthcare for migrants.

Reducing the health care burden for marginalised migrants: The potential role for primary care in Europe.

There is a growing interest in the health of migrants worldwide. Migrants, particularly those in marginalised situations, face significant barriers and inequities in entitlement and access to high quality health care. This study aimed to explore the potential role of primary care in mitigating such barriers and identify ways in which health care policies and systems can influence the ability of primary care to meet the needs of vulnerable and marginalised migrants. The study compared routinely available country-level data on health system structure and financing, policy support for language and communication, and barriers and facilitators to health care access reported in the published literature. These were then mapped to a framework of primary care systems to identify where the key features mitigating or amplifying barriers to access lay. Reflecting on the data generated, we argue that culturally-sensitive primary care can play a key role in delivering accessible, high-quality care to migrants in vulnerable situations. Policymakers and practitioners need to appreciate that both individual patient capacity, and the way health care systems are configured and funded, can constrain access to care and have a negative impact on the quality of care that practitioners can provide to such populations. Strategies to address these issues, from the level of policy through to practice, are urgently needed.

Polylysogeny magnifies competitiveness of a bacterial pathogen in vivo.

The rise of next generation sequencing is revealing a hidden diversity of temperate phages within the microbial community. While a handful of these phages have been well characterized, for the vast majority, the role of phage carriage, and especially multiple phage carriage, is poorly understood. The Liverpool epidemic strain of Pseudomonas aeruginosa is an aggressive pathogen in cystic fibrosis lung infections that has recently been found to contain several unique prophages within its genome. Here, we experimentally investigate the role of two of these phages in vivo, using an insect model of infection. We find that while no benefit is conferred by phage carriage in single bacterial infections, phages confer a large fitness advantage during mixed infections by mediating bacteria-bacteria competition. Differences between the two phages appeared to be associated with the rate at which the competitor acquired the phage, and therefore resistance. However, the advantage was greatest in the polylysogen, carrying both phages. These findings suggest that the LES phages may play an important role in host invasions and more generally show that the carriage of multiple phages may itself be beneficial by hindering the spread of resistance in rival bacterial populations.

Guidelines and training initiatives that support communication in cross-cultural primary-care settings: appraising their implementability using Normalization Process Theory.

BACKGROUND: Guidelines and training initiatives (G/TIs) available to support communication in cross-cultural primary health care consultations are not routinely used. We need to understand more about levers and barriers to their implementation and identify G/TIs likely to be successfully implemented in practice. OBJECTIVE: To report a mapping process used to identify G/TIs and to prospectively appraise their implementability, using Normalization Process Theory (NPT). METHODS: RESTORE is a 4-year EU FP-7 project. We used purposeful and network sampling to identify experts in statutory and non-statutory agencies across Austria, England, Greece, Ireland, Scotland and the Netherlands who recommended G/TI data from the grey literature. In addition, a peer review of literature was conducted in each country. Resulting data were collated using a standardized Protocol Mapping Document. G/TIs were identified for inclusion by (i) initial elimination of incomplete G/TI material; (ii) application of filtering criteria; and (iii) application of NPT. RESULTS: 20 G/TIs met selection criteria: 8 guidelines and 12 training initiatives. Most G/TIs were identified in the Netherlands (n = 7), followed by Ireland (n = 6) and England (n = 5). Fewer were identified in Scotland (n = 2), and none in Greece or Austria. The majority (n = 13) were generated without the inclusion of migrant service users. All 20 were prospectively appraised for potential implementability by applying NPT. CONCLUSIONS: NPT is useful as a means of prospectively testing G/TIs for implementability. Results indicate a need to initiate meaningful engagement of migrants in the development of G/TIs. A European-based professional standard for development and assessment of cross-cultural communication resources is advised.

Communication in cross-cultural consultations in primary care in Europe: the case for improvement. The rationale for the RESTORE FP 7 project.

The purpose of this paper is to substantiate the importance of research about barriers and levers to the implementation of supports for cross-cultural communication in primary care settings in Europe. After an overview of migrant health issues, with the focus on communication in cross-cultural consultations in primary care and the importance of language barriers, we highlight the fact that there are serious problems in routine practice that persist over time and across different European settings. Language and cultural barriers hamper communication in consultations between doctors and migrants, with a range of negative effects including poorer compliance and a greater propensity to access emergency services. It is well established that there is a need for skilled interpreters and for professionals who are culturally competent to address this problem. A range of professional guidelines and training initiatives exist that support the communication in cross-cultural consultations in primary care. However, these are commonly not implemented in daily practice. It is as yet unknown why professionals do not accept or implement these guidelines and interventions, or under what circumstances they would do so. A new study involving six European countries, RESTORE (REsearch into implementation STrategies to support patients of different ORigins and language background in a variety of European primary care settings), aims to address these gaps in knowledge. It uses a unique combination of a contemporary social theory, normalisation process theory (NPT) and participatory learning and action (PLA) research. This should enhance understanding of the levers and barriers to implementation, as well as providing stakeholders, with the opportunity to generate creative solutions to problems experienced with the implementation of such interventions.

REsearch into implementation STrategies to support patients of different ORigins and language background in a variety of European primary care settings (RESTORE): study protocol.

BACKGROUND: The implementation of guidelines and training initiatives to support communication in cross-cultural primary care consultations is ad hoc across a range of international settings with negative consequences particularly for migrants. This situation reflects a well-documented translational gap between evidence and practice and is part of the wider problem of implementing guidelines and the broader range of professional educational and quality interventions in routine practice. In this paper, we describe our use of a contemporary social theory, Normalization Process Theory and participatory research methodology--Participatory Learning and Action--to investigate and support implementation of such guidelines and training initiatives in routine practice. METHODS: This is a qualitative case study, using multiple primary care sites across Europe. Purposive and maximum variation sampling approaches will be used to identify and recruit stakeholders-migrant service users, general practitioners, primary care nurses, practice managers and administrative staff, interpreters, cultural mediators, service planners, and policy makers. We are conducting a mapping exercise to identify relevant guidelines and training initiatives. We will then initiate a PLA-brokered dialogue with stakeholders around Normalization Process Theory's four constructs--coherence, cognitive participation, collective action, and reflexive monitoring. Through this, we will enable stakeholders in each setting to select a single guideline or training initiative for implementation in their local setting. We will prospectively investigate and support the implementation journeys for the five selected interventions. Data will be generated using a Participatory Learning and Action approach to interviews and focus groups. Data analysis will follow the principles of thematic analysis, will occur in iterative cycles throughout the project and will involve participatory co-analysis with key stakeholders to enhance the authenticity and veracity of findings. DISCUSSION: This research employs a unique combination of Normalization Process Theory and Participatory Learning and Action, which will provide a novel approach to the analysis of implementation journeys. The findings will advance knowledge in the field of implementation science because we are using and testing theoretical and methodological approaches so that we can critically appraise their scope to mediate barriers and improve the implementation processes.
