Directly observed therapy and tuberculosis: how can a systematic review of qualitative research contribute to improving services? A qualitative meta-synthesis.

AIM: This paper reports the findings from a qualitative meta-synthesis concerning people with, or at risk of, tuberculosis, service providers and policymakers and their experiences and perceptions of tuberculosis and treatment. BACKGROUND: Directly observed therapy is part of a package of interventions to improve tuberculosis treatment and adherence. A Cochrane systematic review of trials showed an absence of evidence for or against directly observed therapy compared with people treating themselves. METHOD: Qualitative systematic review methods were used to search, screen, appraise and extract data thematic analysis was used to synthesize data from 1990 to 2002, and an update of literature to December 2005. Two questions were addressed: 'What does qualitative research tell us about the facilitators and barriers to accessing and complying with tuberculosis treatment?' and 'What does qualitative research tell us about the diverse results and effect sizes of the randomized controlled trials included in the Cochrane review?' Findings help explain the diverse trial results in a Cochrane systematic review of directly observed therapy and tuberculosis and consider implications for research, policy and practice. FINDINGS: Five themes emerged from the 1990 to 2002 synthesis: socio-economic circumstances, material resources and individual agency; explanatory models and knowledge systems in relation to tuberculosis and its treatment; the experience of stigma and public discourses around tuberculosis; sanctions, incentives and support, and the social organization and social relationships of care. Two additional themes emerged from the 2005 update. CONCLUSION: The qualitative meta-synthesis improved the relevance and scope of the Cochrane review of trials. The findings make a major contribution to the development of theory concerning global WHO-branded disease control and the practicality of local delivery to people.

The role and theoretical evolution of knowledge translation and exchange in public health.

BACKGROUND: There is an increased emphasis in public health research on effective models and strategies to support knowledge translation (KT), the exchange, synthesis and ethically sound application of research findings within a complex set of interactions among researchers and knowledge users. In other words, KT can be seen as an acceleration of the knowledge cycle-an acceleration of the natural transformation of knowledge into use (Canadian Institutes of Health Services Research. Knowledge Translation Strategy, 2004). The most recent conceptualizations consider the complexities of public health decision-making. The role of practitioners and communities is increasingly considered. METHODS: We identify, describe and discuss the theoretical underpinnings of KT and recommend a way forward to build the evidence for more effective practice. RESULTS: Theoretical perspectives increasingly influence research on KT in public health. A range of innovative work is being conducted to explore methods for KT using practical tools, often with the support of government. CONCLUSIONS: KT describes a crucial and to date under-developed element of the research process. There is an important gap in theoretically informed empirical studies of effectiveness of proposed approaches in public health, health promotion and preventive medicine, and thus much of the debate remains abstract. There is clearly an urgent policy need to establish the effectiveness of KT models in a range of contexts. This must include both the consideration of development and the utilization of knowledge.

Extending systematic reviews to include evidence on implementation: methodological work on a review of community-based initiatives to prevent injuries.

Unintentional injury is a leading cause of mortality and disability among young and old. While evidence about the effectiveness of interventions in reducing injuries is accumulating, reviews of this evidence frequently fail to include details of implementation processes. Our research, of which the work reported here formed a part, had two main objectives: (1) to identify evidence about the implementation of interventions aimed at reducing unintentional injuries amongst children and young people; and (2) to explore methods for systematically reviewing evidence on implementation. Existing systematic reviews of the effectiveness of interventions aiming to reduce unintentional injuries in children and young people formed the starting point for the work reported here. In summary, many of the published papers we identified contained little information on implementation processes and, even when these were discussed, the extent to which authors' claims were based on research evidence was unclear. On the basis of the studies we reviewed implementation data were insufficiently strong to provide a sound evidence base for practitioners and policymakers. Notwithstanding this, we identified valuable data about the context in which such initiatives are implemented and the type of factors that might impinge on implementation. This work has implications in three areas: (1) researchers with an interest in evidence-based public health could be encouraged to consider implementation issues in the design of intervention studies; (2) funding bodies could be encouraged to prioritise intervention studies using mixed methods that will enable researchers to consider effectiveness and implementation; (3) journal editors could work towards increasing the quality of reporting on implementation issues through the development of guidelines.

Systematically reviewing qualitative and quantitative evidence to inform management and policy-making in the health field.

Policy-makers and managers have always used a wide range of sources of evidence in making decisions about policy and the organization of services. However, they are under increasing pressure to adopt a more systematic approach to the utilization of the complex evidence base. Decision-makers must address complicated questions about the nature and significance of the problem to be addressed; the nature of proposed interventions; their differential impact; cost-effectiveness; acceptability and so on. This means that Cochrane-style reviews alone are not sufficient. Rather, they require access to syntheses of high-quality evidence that include research and non-research sources, and both qualitative and quantitative research findings. There is no single, agreed framework for synthesizing such diverse forms of evidence and many of the approaches potentially applicable to such an endeavour were devised for either qualitative or quantitative synthesis and/or for analysing primary data. This paper describes the key stages in reviewing and synthesizing qualitative and quantitative evidence for decision-making and looks at various strategies that could offer a way forward. We identify four basic approaches: narrative (including traditional 'literature reviews' and more methodologically explicit approaches such as 'thematic analysis', 'narrative synthesis', 'realist synthesis' and 'meta-narrative mapping'), qualitative (which convert all available evidence into qualitative form using techniques such as 'meta-ethnography' and 'qualitative cross-case analysis'), quantitative (which convert all evidence into quantitative form using techniques such as 'quantitative case survey' or 'content analysis') and Bayesian meta-analysis and decision analysis (which can convert qualitative evidence such as preferences about different outcomes into quantitative form or 'weights' to use in quantitative synthesis). The choice of approach will be contingent on the aim of the review and nature of the available evidence, and often more than one approach will be required.

Mapping the determinants of health inequalities in social space: can Bourdieu help us?

Considerable research effort has been devoted to describing and explaining, at a variety of spatial scales, geographical inequalities in health outcomes within the developed world. Following Bourdieu, we argue that structures of the social world may be revealed in different kinds of 'social' space. We outline the relational thinking that underlies these ideas. We then 'map', using correspondence analysis (on which Bourdieu himself drew), the structure of social space according to the differential availability of some forms of capital, across four study areas in north-west England. We use logistic regression analysis to explain variation in psychological morbidity (GHQ-score) and then portray the significant predictors of morbidity using multiple correspondence analysis. The area of residence of the survey respondents is used to associate them with particular locations in these social spaces.

A proper place to live: health inequalities, agency and the normative dimensions of space.

This paper explores the links between lay knowledge, place and health related social action (or agency) at the individual and collective level. It is based on an analysis of in-depth interviews and neighbourhood survey data across four localities in two cities in the North West of England.The qualitative analysis has identified 'guidelines' that we argue provide socially shared understandings of the normative contours of 'proper places' which shape the way people respond to the everyday lived reality of places. The quantitative findings suggest that a substantial minority of people, particularly in disadvantaged areas, are exposed to significant dissonance between the normative dimensions and lived experience of place. The analysis points to potential interactions between individual and collective action which may affect the health of individuals and populations and 'ontological fit'-people's ability to (re) construct a positive identity despite living in what they and others perceive to be an 'improper' place. This is linked to their biographical connections with particular places and the extent to which they can localise problems and people in places at a distance from themselves. The paper contributes to understanding about the processes that generate inequalities in the health experience of people living in sharply contrasting socio-economic circumstances as well as finer-grained health inequalities between the 'poor' and the 'poorest'.

'Everywhere and nowhere': locating and understanding the 'new' public health.

Public health was recently described as being 'everywhere and nowhere' (Br. Med.J. 319(7213)(1999)839). This image captures the idea that public health is shaped by a range of social, environmental and physiological influences, and that these are mapped across the activities and practices of a range of players. It also suggests it is difficult to capture the spaces of public health. This paper explores how theoretical and methodological developments in the social sciences, in particular ideas around reflexive modernisation, can help us to read the complex terrain of public health policy and practice, and visualise these spaces more clearly.

Beyond 'beer, fags, egg and chips'? Exploring lay understandings of social inequalities in health.

This paper seeks to contribute to the limited body of work that has directly explored lay understandings of the causes of health inequalities. Using both quantitative and qualitative methodology, the views of people living in contrasting socio-economic neighbourhoods are compared. The findings support previous research in suggesting that lay theories about causality in relation to health inequalities, like lay concepts of health and illness in general, are multi-factorial. The findings, however, also illustrate how the ways in which questions about health and illness are asked shape people's responses. In the survey reported on here people had no problem offering explanations for health inequalities and, in response to a question asking specifically about area differences in health experience, people living in disadvantaged areas 'constructed' explanations which included, but went beyond, individualistic factors to encompass structural explanations that gave prominence to aspects of 'place'. In contrast, within the context of in-depth interviews, people living in disadvantaged areas were reluctant to accept the existence of health inequalities highlighting the moral dilemmas such questions pose for people living in poor material circumstances. While resisting the notion of health inequalities, however, in in-depth interviews the same people provided vivid accounts of the way in which inequalities in material circumstances have an adverse impact upon health. The paper highlights ways in which different methodologies provide different and not necessarily complementary understandings of lay perspectives on the causes of inequalities in health.

Developing a model to enhance the capacity of statutory organisations to engage with lay communities.

OBJECTIVE: To understand the processes that constrain the capacity of statutory organisations to work effectively with lay communities and to develop a model to enhance their capacity to do so. METHODS: The research consisted of three elements: a review of relevant literature; in-depth interviews with a purposive sample of people who had recently been involved in community-statutory sector partnership; and a deliberative workshop involving ten expert witnesses, selected to reflect a range of sectors and levels within organisations. RESULTS: Many factors contribute to a lack of effective strategic partnerships between lay communities and statutory organisations. These factors fall into five domains: the community's capacity to engage; the skills and competencies of organisational staff; the dominant professional service culture; the overall organisational ethos and culture; and the dynamics of the local and national political systems. A model of the relationships and/or interaction between these domains is postulated. There is potential for testing this model with statutory organisations to see whether it concurs with their reality and whether it is enhancing their organisational capacity. CONCLUSIONS: Commonly occurring constraints to effective partnerships between statutory organisations and lay communities need to be identified and addressed by applying a dynamic model of the type presented here.

Total purchasing, community and continuing care: lessons for future policy developments in the NHS.

The introduction of total purchasing pilots (TPPs) into the National Health Service (NHS) gave general practitioners (GPs) significant new opportunities to take responsibility for the development of community and continuing care (CCC) services. Based on five case studies of TPPs involved in developing CCC this paper asks three questions: (1) to what extent were the TPP's involvement in CCC informed by an awareness of CCC policy?; (2) were TPPs involved in joint commissioning to develop integrated purchasing or provision which was informed by population based needs assessment?; (3) were TPPs seeking to involve users, carers and voluntary agencies in their plans? The findings indicate that TPPs showed little awareness of national or local policy for CCC, although their project initiatives did address some of the policy issues (in particular a recognition of the need for joint working at the practice level). At the time of fieldwork, four of the case study TPPs had begun to investigate the potential for integrated purchasing, and three of them had relatively sophisticated models of both horizontally and vertically integrated provision of care. However, the TPPs developments were not based on systematic population based needs assessment. The paper concludes that there is potential for the primary care led groups proposed in the recent white papers in England, Scotland and Wales to improve integration of care both horizontally and vertically. However, they may need policy guidance and push to: encourage them to put CCC high on their agenda for action; to work with people with expertise in population based, prevention focused, needs assessment; and to find innovative ways to include users, carers and voluntary agencies. Incentives or levers (such as control over budgets) may be needed to promote joint working between staff in different agencies.
