Effectiveness and Coverage of Treatment for Severe Acute Malnutrition Delivered by Community Health Workers in the Guidimakha Region, Mauritania

Geographical and economic access barriers to health facilities (HF) have been identified as some of the most important causes of the low coverage of severe acute malnutrition (SAM) treatment. The objective of this study is to assess the effectiveness and coverage of SAM treatment delivered by community health workers (CHWs) in the Guidimakha region in Mauritania, compared to the HF based approach. This study was a nonrandomized controlled trial, including two rural areas. The control group received outpatient treatment for uncomplicated SAM from HF, whilst the intervention group received outpatient treatment for uncomplicated SAM from HF or CHWs. A total of 869 children aged 6–59 months with SAM without medical complications were included in the study. The proportion of cured children was 82.3% in the control group, and 76.4% in the intervention group, we found no significant difference between the groups. Coverage in the intervention zone increased from 53.6% to 71.7%. In contrast, coverage remained at approximately 44% in the control zone from baseline to end-line. This study is the first to demonstrate in Mauritania that the decentralization model of CHWs treating SAM improves acute malnutrition treatment coverage and complies with the international quality standards for community treatment of acute malnutrition. The non-randomized study design may limit the quality of the evidence, but these results could be used by political decision-makers as a first step in revising the protocol for acute malnutrition management.

Behaviour change interventions to reduce risky substance use and improve mental health in children in care: the SOLID three-arm feasibility RCT

Background

Looked-after children and care leavers (henceforth children in care) are young people placed under the care of local authorities, often because of a history of family abuse and/or neglect. These young people have significantly increased risk of substance use and mental health problems compared with peers.

Aim

The Supporting Looked After Children and Care Leavers In Decreasing Drugs, and alcohol (SOLID) trial aimed to investigate the feasibility of a definitive randomised controlled trial comparing two behaviour change interventions to reduce risky substance use (illicit drugs and alcohol) in and improve the mental health of children in care aged 12–20 years.

Methods

The study consisted of two phases: (1) a formative phase that adapted the motivational enhancement therapy and social behaviour and network therapy interventions for use with children in care and (2) a three-arm pilot randomised controlled trial (comparing motivational enhancement therapy, social behaviour and network therapy and usual care), and a linked process and economic (return on investment) evaluation. Trial feasibility was compared with prespecified STOP/GO criteria.

Setting

Six local authority areas in the north-east of England.

Participants

Children in care (aged 12–20 years) who screened positive for drug and/or alcohol use within the last 12 months were eligible for the trial. The formative and process evaluations included children in care, carers, social workers, and drug and alcohol workers.

Outcome measures

The primary outcomes were recruitment and retention rates at 12 months’ follow-up. Baseline and 12-month follow-up questionnaires measured self-reported drug and alcohol use, mental health and health-related quality of life. The process evaluation considered acceptability and engagement with the interventions and trial procedures.

Results

Formative findings (n = 65) highlighted the need for interventions to increase the emphasis on therapeutic relationships, use creative methods of engagement and support the identification of treatment goals wider than substance misuse. Within the randomised controlled trial, of 860 participants screened, 211 (24.5%) met the inclusion criteria. One hundred and twelve (53%) of the 211 eligible children were recruited and randomised. Just 15 of the 76 (20%) participants allocated to intervention attended any of the motivational enhancement therapy of social behaviour and network therapy sessions, and 60 (54%) participants completed the 12-month follow-up. The screening and recruitment of children in care required significantly more time and resource investment by researchers and children’s services than planned. The process evaluation (n = 116) demonstrated that, despite participants engaging in risky substance use, they did not often acknowledge this nor felt that they needed help. Children in care had complex, chaotic lives and children’s services departments were less research mature and extremely stretched; this, coupled with the multiple steps in the intervention pathway and study protocol, resulted in low adherence to the intervention and the trial.

Conclusions

The SOLID trial demonstrated successful engagement with children in care to adapt the motivational enhancement therapy and social behaviour and network therapy interventions. However, the pilot randomised controlled trial found that a definitive trial is not feasible. The current screen, refer and treat pathway for children in care did not work. There is an urgent need to radically rethink how we deliver therapeutic services for children in care. A pragmatic evaluation design, coupled with additional research resource for children’s services, is needed to evaluate these novel models of care at scale.

Towards new ways of assessing the impact of local medical journals: A proposal and call for change

The relevance of research output to the local community is critical to changing practice. Research relevance has to be determined using measurements that show that the knowledge that arose from that research has made an impact on society. This paper, based on a literature review and preliminary research results, advocates for research impact measurements which take account of local contexts when evaluating the relevance of a journal article or indeed any research output. It concludes that a journal should go beyond traditional measurement metrics of citation analysis and bibliometrics alone as a measure of research impact. Although it is important to standardise measurements, it is also important that local communities should be encouraged to choose measurements of research output that matter to them. The proposed ways of assessing research impact are: (a) change in policies in the health sector, (b) effect on local medical treatment guidelines, (c) effect on case management, (d) use in continuous professional development, and (e) impact on local knowledge production.

Implementation of evidence-based medicine in a health promotion teaching block for Thai medical students

BACKGROUND

Evidence-based medicine (EBM) is well known in medical practice. Although health promotion (HP) is promoted worldwide, there is still some debate as to whether EBM is needed or useful in the teaching of health promotion.

OBJECTIVE

To assess the perceived usefulness of EBM in the teaching of HP among medical students and faculty members.

METHODS

A comparative study was conducted between two groups of fourth-year medical students in the academic year 2012 during the five-week Health Promotion Teaching Block at Prince of Songkla University, southern Thailand. A one-week EBM course was conducted with half the students in the first week of the block and the other half of the students in the last week of the block. All activities in the HP block were similar except for the different periods of the one-week of EBM teaching. The effect on knowledge, ability and perceived application of EBM in future practice was assessed by student self-evaluations before versus after taking the EBM course, and by faculty member evaluation of the students' end-of-block presentations. All evaluation items were rated from 1 (lowest) to 5 (highest). Data were analyzed using a t-test or Wilcoxon test, as appropriate.

RESULTS

The students' self-evaluations of knowledge and ability on EBM between the two groups were similar. The perception that teaching EBM is beneficial in health promotion and future practice increased significantly ( p<0.001) in both groups. Faculty members rated higher scores for the first group than the second group, although the rating differences were not at the level of significance. Ninety percent of the students believed that EBM was a useful addition to the teaching of HP.

CONCLUSIONS

Medical students and faculty members perceived that EBM is useful in the HP context. Future studies to evaluate the effect of using evidence-based teaching for health promotion are needed.

Academic practice-policy partnerships for health promotion research: experiences from three research programs

BACKGROUND

The development of knowledge for health promotion requires an effective mechanism for collaboration between academics, practitioners, and policymakers. The challenge is better to understand the dynamic and ever-changing context of the researcher-practitioner-policymaker-community relationship.

AIMS

The aims were to explore the factors that foster Academic Practice Policy (APP) partnerships, and to systematically and transparently to review three cases.

METHODS

Three partnerships were included: Power and Commitment-Alcohol and Drug Prevention by Non-Governmental Organizations in Sweden; Healthy City-Social Inclusion, Urban Governance, and Sustainable Welfare Development; and Empowering Families with Teenagers-Ideals and Reality in Karlskoga and Degerfors. The analysis includes searching for evidence for three hypotheses concerning contextual factors in multi-stakeholder collaboration, and the cumulative effects of partnership synergy.

RESULTS

APP partnerships emerge during different phases of research and development. Contextual factors are important; researchers need to be trusted by practitioners and politicians. During planning, it is important to involve the relevant partners. During the implementation phase, time is important. During data collection and capacity building, it is important to have shared objectives for and dialogues about research. Finally, dissemination needs to be integrated into any partnership. The links between process and outcomes in participatory research (PR) can be described by the theory of partnership synergy, which includes consideration of how PR can ensure culturally and logistically appropriate research, enhance recruitment capacity, and generate professional capacity and competence in stakeholder groups. Moreover, there are PR synergies over time.

CONCLUSIONS

The fundamentals of a genuine partnership are communication, collaboration, shared visions, and willingness of all stakeholders to learn from one another.

Compliance with physical exercise: using a multidisciplinary approach within a dose-dependent exercise study of moderately overweight men

AIMS

Sixty-one healthy, sedentary, moderately overweight young men participated in a randomised controlled trial to examine the effects of two different doses of endurance exercise on health behaviour and exercise compliance.

METHODS

Participants were randomised to a sedentary control group, a moderate (MOD; 300 kcal/day) or a high-dose (HIGH; 600 kcal/day) endurance exercise group for 12 weeks. A sub-set of the subjects were interviewed using pre-determined, qualitative questions to elucidate physical activity and health behaviour. In combination with the Theory of Planned Behaviour (TPB), a post hoc thematic analysis was conducted to connect qualitative and quantitative data in a joint analysis.

RESULTS

Of the subjects interviewed, exercise compliance expressed as 95% CI was [96.8; 103%] in the MOD group and [82.9; 99.6%] in the HIGH group. The different doses of daily exercise equally improved various metabolic health parameters. The MOD group was untroubled by the exercise load and had a positive attitude towards exercise. The HIGH group expressed increased fatigue, less positivity and perceived exercise as time-consuming. The MOD group described themselves as more energetic, and thereby may have increased physical activity levels in areas of their everyday lives that were not related to the intervention.

CONCLUSIONS

A multidisciplinary approach provided explanations for similar effects of two different doses of exercise. This could not have been determined via either qualitative or quantitative methodology alone. The preconditions of the TBP were fulfilled, and it represents a methodological model to explain the high degree of compliance and motivation to exercise.

Evidence for Healthy Cities: reflections on practice, method and theory

The European Healthy Cities project can be characterized as a social movement that employs an extremely wide range of political, social and behavioural interventions for the development and sustenance of urban population health. At all of these levels, the movement is inspired by ideological, theoretical and evidence-based perspectives. The result of this stance is a dynamic, complex and diverse landscape of initiatives, plans, programmes and actions. In quantitative terms (the number of WHO designated cities and associated cities and communities through national networks), 'Healthy Cities' can be regarded as an extraordinary accomplishment and a credit for both WHO and cities in the movement. In qualitative terms, however, critics of the movement have maintained that little evidence on its success and effectiveness has been generated. This critique finds its foundations in the mere perceptions of evidence, the politics of science and urban governance, and perspectives on the preferred or professed utilities of evidence-based health notions. The article reviews the nature of evidence and its interface with politics and governance. Applying a conceptual framework combining insights from knowledge utilization theory, theoretical perspectives on (health) policy development, theory-based evaluations and planned intervention approaches, it demonstrates that, although the evidence is overwhelming, there are barriers to the implementation of such evidence that should be further addressed by 'Healthy Cities'.

Healthy settings: challenges to generating evidence of effectiveness

This paper starts by briefly reviewing the history, theory and practice of the settings approach to promoting public health--highlighting its ecological perspective, its understanding of settings as dynamic open systems and its primary focus on whole system organization development and change. It goes on to outline perceived benefits and consider why, almost 20 years after the Ottawa Charter advocated the approach, there remains a relatively poorly developed evidence base of effectiveness. Identifying three key challenges--relating to the construction of the evidence base for health promotion, the diversity of conceptual understandings and real-life practice and the complexity of evaluating ecological whole system approaches--it suggests that these have resulted in an ongoing tendency to evaluate only discrete projects in settings, thus failing to capture the 'added value' of whole system working. It concludes by exploring the potential value of theory-based evaluation and identifying key issues that will need to be addressed in moving forward--funding evaluation within and across settings; ensuring links between evidence, policy and practice; and clarifying and articulating the theories that underpin the settings approach generically and inform the approach as applied within particular settings.

Evaluating the effect of policies and interventions to address inequalities in health: lessons from a Dutch programme

OBJECTIVES

Many initiatives have been taken in European countries that are designed to reduce inequalities in health. However, the effects of only a very few of these initiatives have been assessed. The main aim of a Dutch research and development programme was to systematically investigate and evaluate interventions aimed at reducing inequalities in health. In this paper, we report on this investigation, and draw lessons from the methodology used to evaluate such interventions.

APPROACH

The programme included 12 evaluation studies, focusing on the wider determinants of inequalities in health (n = 2), behavioural determinants (n = 4), working conditions (n = 3) and health care (n = 3).

RESULTS

An experimental design was applied in two evaluation studies. The studies provided evidence of a positive effect. A quasi-experimental design appeared to be the only attainable option in seven studies. Five of these provided sufficient evidence for a positive effect, but two interventions appeared not to be successful. In three studies, no experimental or quasi-experimental design could be applied.

CONCLUSIONS

The programme showed that it is possible to apply experimental or quasi-experimental studies to complex public health interventions. The Programme Committee steering the programme considered that the evidence generated by the experimental and quasi-experimental studies justified the implementation of the interventions on a wider scale, accompanied by further evaluation studies. Further development of the methodology of public health interventions is necessary. These include non-experimental designs such as international comparisons and time trend studies, especially in order to be able to evaluate broader policy measures.
