Bridging the gap: Translating research into policy and practice

Effective physical activity interventions do not achieve their full potential if they are not applied beyond their original testing in research studies. Potentially effective interventions can be adopted in community settings through the efforts of numerous agencies, organizations, and individuals. This paper highlights the important roles of public health practitioners and policy makers, who differ in their decision-making processes. To enhance the uptake of evidence-based interventions, several steps are needed to: build the science by moving upstream, increase the understanding of practice-based evidence, move beyond the “what” to the “how,” re-frame the dissemination challenges, place greater emphasis on workforce development, and make research more accessible for policy audiences. The most effective strategies to bridge the gap between research and practice, will have at their heart, effective academic-practice-policy maker partnerships.     

Intelligent policy making? Key actors' perspectives on the development and implementation of an early years' initiative in Scotland's public health arena

Increased political enthusiasm for evidence-based policy and action has re-ignited interest in the use of evidence within political and practitioner networks. Theories of evidence-based policy making and practice are being re-considered in an attempt to better understand the processes through which knowledge translation occurs. Understanding how policy develops, and practice results, has the potential to facilitate effective evidence use. Further knowledge of the factors which shape healthcare delivery and their influence in different contexts is needed.This paper explores the processes involved in the development of a complex intervention in Scotland's National Health Service (NHS). It uses a national oral health programme for children (Childsmile) as a case study, drawing upon key actors' perceptions of the influence of different drivers (research evidence, practitioner knowledge and values, policy, and political and local context) to programme development. Framework analysis is used to analyse stakeholder accounts from in-depth interviews. Documentary review is also undertaken.Findings suggest that Childsmile can be described as an ‘evidence-informed’ intervention, blending available research evidence with knowledge from practitioner experience and continual learning through evaluation, to plan delivery. The importance of context was underscored, in terms of the need to align with prevailing political ideology and in the facilitative strength of networks within the relatively small public health community in Scotland. Respondents' perceptions support several existing theoretical models of translation, however no single theory offered a comprehensive framework covering all aspects of the complex processes reported. Childsmile's use of best available evidence and on-going contribution to knowledge suggest that the programme is an example of intelligent policy making with international relevance.     

Health-seeking strategies and sexual health among female sex workers in urban India: Implications for research and service provision

This paper presents and discusses selected findings from a study of health-seeking strategies in relation to sexual health among a group of female sex workers in Calcutta, India. Background information on sex work and sexually transmitted disease in Calcutta is followed by the presentation of findings pertaining to women's understandings of (sexual) health, treatment-seeking and service utilisation. In the urban context where health services are readily available, patterns of initial treatment-seeking are shown to be generally (biomedically) appropriate, but subsequent “non-compliant” therapeutic practices give cause for concern. Conventional approaches to the study of “health-seeking behaviour” are reviewed in the light of these findings and questions raised about the appropriateness of approaches that focus on initial choice of treatment type and/or assume processes of health-seeking to be determined primarily by cultural “beliefs” about illness. Inherent biomedical and culturalist biases in the orientation of such research are shown to produce an analytic neglect of the dual influences of material life conditions and people's perceptions of health, rather than illness, upon health-related strategies. Recommendations are made for operational research and policy formulation on the provision of effective sexual health services, and implications are drawn for the scope of interventions and applied research directed at improving sexual health.     

Dissecting Obesogenic Environments: The Development and Application of a Framework for Identifying and Prioritizing Environmental Interventions for Obesity

Background. The “obesogenicity” of modern environments is fueling the obesity pandemic. We describe a framework, known as ANGELO (analysis grid for environments linked to obesity), which is a conceptual model for understanding the obesogenicity of environments and a practical tool for prioritizing environmental elements for research and intervention.Methods: Development of the ANGELO framework. The basic framework is a 2 × 4 grid which dissects the environment into environmental size (micro and macro) by type: physical (what is available), economic (what are the costs), political (what are the “rules”), and sociocultural (what are the attitudes and beliefs). Within this grid, the elements which influence food intake and physical activity are characterized as obe sogenic or “leptogenic” (promoting leanness).Results: Application of the ANGELO framework. The ANGELO framework has been piloted at the population level (island communities) to prioritize the settings/sectors for intervention and at the setting level (fast food outlets) to prioritize research needs and interventions. Environmental elements were prioritized by rating their validity (evidence of impact), relevance (to the local context), and potential changeability.Conclusions. The ANGELO framework appears to be a flexible and robust instrument for the needs analysis and problem identification stages of reducing the obe sogenicity of modern environments.     

Evaluating water supply and other health programs: Short-run vs long-run mortality effects

Development agencies use “cost-effectiveness” analyses for setting priorities among Primary Health Care programs, with “effectiveness” often measured by the short-term impact on young-child mortality. Using data on the long-term effects of water supply and sanitation improvements on mortality in urban France in the 19th century, it is shown that use of this criterion introduces systematic and serious biases in favour of specific medical interventions and against systemic environmental interventions.

The Role of “Evidence” in Recovery from Mental Illness

Evidence-based practice (EBP), a derivative of evidence-based medicine (EBM), is ascendant in the United States’ mental health system; the findings of randomized controlled trials and other experimental research are widely considered authoritative in mental health practice and policy. The concept of recovery from mental illness is similarly pervasive in mental health programming and advocacy, and it emphasizes consumer expertise and self-determination. What is the relationship between these two powerful and potentially incompatible forces for mental health reform? This paper identifies four attempts, in the mental health literature, to delineate the role of “evidence” in recovery. One is the strong version of evidence-based practice—an applied science model—and three others address weaknesses in the first by limiting the authority of probabilistic findings. The paper also offers a fifth version, based on the concept of communicative accountability, which is derived from Habermas’ work on communicative action. The fifth version responds to the other four and emphasizes learning, disclosure and respect in clinical and other helping relationships.     

The impact of global health initiatives on the health system in Angola

We assessed the impact of global health initiatives (GHIs) on the health care system of Angola, as a contribution to documenting how GHIs, such as the Global Fund, GAVI and PEPFAR, influence the planning and delivery of health services in low-income countries and how national systems respond. We collected the views of national and sub-national key informants through 42 semi-structured interviews between April 2009 and May 2011 (12 at the national level and 30 at the sub-national level). We used a snowball technique to identify respondents from government, donors and non-governmental organisations. GHIs stimulated the formulation of a health policy and of plans and strategies, but the country has yet to decide on its priorities for health. At the regional level, managers lack knowledge of how GHIs’ function, but they assess the effects of external funds as positive as they increased training opportunities, and augment the number of workers engaged in HIV or other specific disease programmes. However, GHIs did not address the challenge of attraction and retention of qualified personnel in provinces. Since Angola is not entirely dependent on external funding, national strategic programmes and the interventions of GHIs co-habit well, in contrast to countries such as Mozambique, which heavily depend on external aid.     

What influences the transfer of research into health policy and practice? Observations from England and Australia

OBJECTIVES: To explore the role of evidence in the public health policy-making process, and show how the way in which public health problems are defined and measured influences policy outcomes. METHODS: The policy responses of the Blair Labour Government in the UK and the Howard Coalition Government in Australia to persistent health inequalities over the last decade are examined as a case study. RESULTS: Soon after being elected, the Blair Government commissioned an independent inquiry into health inequalities, signalling the priority it gave to addressing this longstanding challenge. It chose to take a 'whole-of-government' approach, combining actions that addressed both personal risk factors and the social determinants of health. This approach reflects the long-established tradition in England of routinely measuring disparities in health outcomes and correlating them with socio-economic status and underlying social determinants of health. Over the same period, the Howard Government also outlined its 'whole-of-government' approach to addressing the most extreme and persistent health inequalities between indigenous and non-indigenous Australians. In contrast, its approach focused primarily on modifying risk factors and improving service provision. This approach reflects the different historical circumstances in Australia and a different tradition in the collection of health data, focused more on health service access and personal risk factors. CONCLUSIONS: This case study offers some insight into the ways in which the production and presentation of evidence can influence and shape governmental responses to public health problems. The usefulness of available evidence is dependent upon the type of data that is produced routinely by government, as well as more deliberate decisions concerning public health research funding. Researchers can maximize the influence of research evidence on the policy process by engaging in the policy-making process, presenting research in ways that fit with the political context of the day, and, where necessary, using research evidence in public health advocacy in order to influence political priorities more directly.     

Health and housing conditions in public sector housing estates

This article reports some of the findings of a study of health and housing conditions ina sample of households from eight different types of council housing areas in Gateshead.Controlling for age, there were found to be marked and consistent differences in self-reported health between individuals from different areas. For all age groups up to 65 years old, those living in “bad” housing areas reported poorer health, more long-standing illness, more recent illness and more symptoms of respiratory disease and depression. The clearest associations between poor health and bad housing emerged for the generally fittest age-groups (the under 25 years). For the people over 65 years the position was reversed, with those in “good” housing areas reporting poorer health, with the exception of recent illness. This is argued to be the result of local authority lettings policy, which gives priority to re-housing the less-fit elderly.Those in “bad” housing areas were also more likely to report housing defects which affected their health and to feel that their health could be improved by a change in their housing.The study found that “bad” council housing areas did not necessarily conform to thestereotype of non-traditional construction, or high-rise flats. Some consisted of traditionally built houses, while there was a sizeable representation among the “good” housing of system-built high-rise flats. The “bad” housing areas were marked off more by their location, their poor environment and the low quality of their construction.     

Consumer perception of bread quality

Bread contains a wide range of important nutritional components which provide a positive effect on human health. However, the consumption of bread is declining during the last decades. This is due to factors such as changing eating patterns and an increasing choice of substitutes like breakfast cereals and fast foods. The aim of this study is to investigate consumer's quality perception of bread towards sensory, health and nutrition attributes. Four consumer segments are identified based on these attributes. The different consumer segments comprise consumers being positive to all three quality aspects of bread (“enthusiastic”) as wells as consumers perceiving bread strongly as “tasteless”, “non-nutritious” or “unhealthy”. Moreover, factors are identified which influence the consumers’ quality perception of bread. The results of our study may help health professionals and policy makers to systematically inform consumers about the positive effects of bread based on its components. Furthermore, firms can use the results to build up tailor-made marketing strategies.     

Effectiveness and efficiency of a literature search strategy to answer questions on the etiology of occupational diseases: a controlled trial

Objectives To evaluate the effectiveness and efficiency of a search strategy to find evidence-based answers to questions related to the possible occupational etiology of diseases. Methods A controlled trial of 70 occupational health physicians and 55 insurance physicians who were asked to answer one out of four ‘occupational disease case-vignettes’ following the steps of evidence-based medicine (EBM). The intervention group were given the search strategy as a tool. Results The intervention group scored significantly better than the control group in answering the main question of the case-vignette correctly (57% versus 37%) using more adequate search terms. The intervention group scored significantly better regarding satisfaction with the applied search strategy (28% very satisfied versus 8%). We found no differences in time spent in solving the case or in the intention of future practice of EBM. Conclusions The introduction and application of specific search strategies can have a positive effect on the effectiveness of searching literature. Future initiatives for developing and testing specific search strategies in the field of occupational health should be encouraged.     

Patient-based medicine: aligning patients’ perspectives on disease and treatment with evidence-based medicine criteria

Background  In Germany, evidence-based medicine (EBM) is increasingly used to standardise medical decision making and patient treatment. As a consequence this development leads to a shift of influence in health care decision making from physicians to institutional representatives, payers and health care policy makers. However, EBM’s practical role in day-to-day patient care is less clearly defined. Aim  The aim of this study was to evaluate a potential difference between EBM assessment of therapy benefits and empirical judgment by prescribing physicians and their patients. Methods  Interviews were conducted with practising physicians to evaluate reasons for selecting treatments and attitudes towards EBM. The physicians’ view was complemented by a patient telephone survey evaluating treatment satisfaction in selected indications. Results  The findings of the physician survey suggest that many general practitioners (GPs) as well as specialized practitioners in Germany do not share EBM’s paramount concern with clinical effectiveness, but see it as one aspect in a wider concept that also includes patient-oriented concerns such as patient satisfaction, minimal infliction on patients’ day-to-day life and incompatibility with other needs or treatments. Another important finding is the notion that EBM is misused by health care policy aimed at restricting clinical practice options by focussing entirely on clinical effectiveness without considering the complex physician-patient interaction required for implementing a successful treatment process. Results from the patient survey reveal the patients’ expectation that their individual needs as well as their personal experiences with a given therapy are being considered and that a dialogue between patient and physician shall guide the course of treatment with the aim of finding an optimal balance between EBM-derived therapy effectiveness and individual, patient-based assessment of a particular treatment approach with respect to entirely subjective impressions and judgments. Discussion  The results of this study demonstrate that practising physicians consider not only evidence-based information, but also patient-oriented criteria to achieve adequate patient care and compliance. Patients wish to discuss disease and personal therapy experiences with their physician and emphasize their intention to actively participate in the treatment process. Therefore, the concept of patient-based medicine is proposed as an extension of current EBM practice in everyday patient treatment as well as for regulatory decision making regarding health care services.     

Who contextualises clinical epidemiological evidence? A political analysis of the problem of evidence-based medicine in the layered Dutch healthcare system

We critically examine the discussion on the role of evidence-based medicine (EBM) in healthcare governance. We take the institutionally layered Dutch healthcare system as our case study. Here, different actors are involved in the regulation, provision and financing of healthcare services. Over the last decades, these actors have related to EBM to inform their actor specific roles. At the same time, EBM has increasingly been problematised. To better understand this problematisation, we organised focus groups and interviews. We noticed that particularly EBM’s reductionist epistemology and its uncritical use by ‘professional others’ are considered problematic. However, our analysis also reveals that something else seems to be at stake. In fact, all the actors involved underwrite EBM’s reductionist epistemology and emphasise that evidence should be contextualised. They however do so in different ways and with different contexts in mind. Moreover, the ways in which some actors contextualise evidence has consequences for the ways in which others can do the same. We therefore emphasise that behind EBM’s scientific problematisation lurks a political issue. A dispute over who should contextualise evidence how, in a layered healthcare system with interdependent actors that cater to both individual patients and the public. We urge public administration scholars and policymakers to open-up the political confrontation between healthcare actors and their sometimes irreconcilable, yet evidence-informed perspectives.     

Impacts of sensory attributes and emotional responses on the hedonic ratings of odors in dairy products

Consumers often decide to purchase certain items as a result of prompt emotional responses evoked by the products; therefore, it is important to investigate the emotional responses stimulated by food samples, as well as the sensory attributes of the products. The aim of this study was to examine influences of sensory attribute and emotional response on olfactory hedonic ratings of dairy products. Additionally, we compared this effect between women and men subjects. Sensory attributes of six natural odors produced by commercial dairy products were evaluated by 9 trained panelists. In addition, 100 untrained panelists (50 women and 50 men) rated the emotional response stimulated by the 6 odors using 25 paired semantic differential scales and the hedonicity using a 9 cm line scale, respectively. Untrained panelists more liked “sweet aromatics,” “sour aromatics,” “fermented aromatics,” and “rich aromatics” over the other sensory attributes of dairy products. The olfactory hedonic ratings were increased when the odor was more characterized as “fragrant,” “attractive,” “comfortable,” “familiar,” “faint,” “natural,” or “modern.” Specific sensory attributes were found to be related to specific adjective pairs representing the emotional response. Moreover, the ratings of adjective pairs representing emotional response of odors and their influences on hedonic ratings differed significantly between sexes. In conclusion, our findings suggest that the emotional responses as well as the sensory attributes affect the hedonic ratings of odors in dairy products.     

Context matters: Successes and challenges of intrapartum care scale-up in four districts of Afghanistan

Reducing preventable maternal mortality and achieving Sustainable Development Goal targets for 2030 will require increased investment in improving access to quality health services in fragile and conflict-affected states. This study explores the conditions that affect availability and utilisation of intrapartum care services in four districts of Afghanistan where mortality studies were conducted in 2002 and 2011. Information on changes in each district was collected through interviews with community members; service providers; and district, provincial and national officials. This information was then triangulated with programme and policy documentation to identify factors that affect the coverage of safe delivery and emergency obstetric care services. Comparison of barriers to maternal health service coverage across the four districts highlights the complexities of national health policy planning and resource allocation in Afghanistan, and provides examples of the types of challenges that must be addressed to extend the reach of life-saving maternal health interventions to women in fragile and conflict-affected states. Findings suggest that improvements in service coverage must be measured at a sub-national level, and context-specific service delivery models may be needed to effectively scale up intrapartum care services in extremely remote or insecure settings.

Concept of evidence-based medicine: a new challenge to epidemiology and preventive medicine

In the last decade evidence-based medicine (EBM) has become popular between clinicians and epidemiologists as a tool to facilitate the translation of scientific research into clinical practice. The concept applicable to public health follows the same principles, but some additional aspects have to be considered. For example, in preventive medicine, there is the strong need to compare the relative effectiveness of various interventions in prolonging survival or preventing the occurrence or complications of a disease both at the population and at the individual level, since it is crucial for setting preventive priorities and health policy making. Traditionally, systematic reviews and meta-analyses quantify the effects of treatments on selected endpoints (health outcomes). However, in setting preventive priorities the reverse perspective is important. Moreover, the judgement about preventive action cannot be done without an adequate consideration of ethical and social context. In view of emerging evidence-based approach in preventive medicine the teaching of evidence-based medicine to health professionals became a new challenge.     

Development of a policy-relevant child maltreatment research strategy

Child maltreatment is associated with a huge burden of suffering, yet there are serious gaps in knowledge about its epidemiology and approaches to intervention. This article describes the development of a proposed national research framework in child maltreatment, as requested by the Department of Justice, Canada, based on (1) a review of the literature, (2) consultation with experts, and (3) application of evaluation criteria for considering research priorities. The article identifies gaps in knowledge about child maltreatment in Canada and proposes a research agenda to make evidence-based policy decisions more likely. Although this work was driven by gaps in Canada's knowledge about child maltreatment, the international scope of the review and consultation process could make the findings useful to broader research and policy audiences.     

When the standards aren't standard: Evidence-based medicine in the Russian context

This paper examines the uses of evidence-based medicine (EBM) in post-Soviet Russia through the use of semi-structured interviews. It asks what it means to talk about practicing evidence-based medicine in a setting where the context of practice presents considerable barriers to the implementation of EBM principles. Drawing on interviews with Russian physicians, medical students and users of the healthcare system, the paper argues that in post-Soviet Russia EBM serves as a strategic discourse for segments of the medical profession. With the collapse of the U.S.S.R. the healthcare system has been going through a period of crisis, and Russian physicians are finding that they have to redefine their professional identity with respect to the domestic and the international context and have to seek new sources for legitimating their professional position. The western origins of EBM endow this rhetoric with considerable power in the Russian context and render it a very useful tool in the project of redefinition.
