Criteria for evaluating evidence on public health interventions

Active Lives South Australia health economic analysis: an evidence base for the potential of health promotion strategies supporting physical activity guidelines to reduce public health costs while improving wellbeing

Aim

The COVID-19 pandemic has threatened individual and population wellbeing and strategies to jointly address these challenges within budget constraints are required. The aim of our research is to analyse evidence from the Active Lives South Australia study to consider the potential of physical activity (PA) health promotion strategies to be health-system cost saving while addressing wellbeing challenges.

Methods

The Active Lives South Australia study compares adult populations who meet and do not meet physical activity (PA) guidelines (150+ minutes of weekly physical activity) with respect to their subjective wellbeing and health care utilisation.

Subject and results

Adults who met PA guidelines had better wellbeing across all aspects with and without adjustment for age, sex and income covariates. Analysis showed significant associations between meeting guidelines and lower probabilities of visiting and utilisation of GPs, specialist doctors, other health professionals, hospital inpatient admissions, outpatient clinic and emergency department visits, and an overall A$1760 lower cost per person annually. Controlling for age, sex and income, health expenditure for adults who met PA guidelines was significantly lower by A$1393 per person annually. That translated to A$804 million potential annual SA health system cost saving by shifting all adults to meeting PA guidelines.

Conclusion

There is significant potential for effective health promotion strategies to be net cost saving while addressing wellbeing challenges of COVID-19 recovery where they can shift target populations from not meeting to meeting PA guidelines.

11 years of regular access to subsidized veterinary services is associated with improved dog health and welfare in remote northern communities

Access to veterinary services can have positive impacts on animal health and welfare, and on human mental and physical health and well-being; however, many communities worldwide lack access to such services. At their request, the 5 communities of the Sahtu Settlement Area, Northwest Territories, Canada, have received annual access to preventive veterinary services through the University of Calgary's Northern Community Health Rotation since 2008. To determine the reach of the program, we conducted a dog census in 2017. We then conducted a chart review of 11 years of dog medical records from 2008 to 2018 to evaluate how the reach of the program, the uptake of veterinary services, and dog population demographics, health and welfare measures changed over the duration of the program. In the chart review, we used either multi-level logistic regression or generalized linear models, to determine how seven variables, including age, sex, breed, body condition, deworming, vaccination, and sterilization status upon clinic entry, changed over the course of program delivery. Our results suggest that program reach, veterinary service uptake, and dog demographic, health and welfare measures improved over time. We observed high rabies vaccination coverage in some communities (48 %-83 % of the dog population) and moderate overall sterilization status (25 %-56 % of the dog population) with female dog sterilization more common than male (75 % of dogs leaving the 2017 clinics, compared to 43 %). Several dog demographic, health, and welfare measures, including age, body condition, and vaccination, deworming, and sterilization status, were significantly better in later years of the program (all p < 0.001). Differences among communities, both in dog population numbers from the 2017 census (40-89 dogs) and in the uptake of veterinary services in 2017 (48 %-83 % of the dog population), were notable. Vaccination uptake was directly related to clinic attendance, but sterilization was impacted by additional factors, including community members' acceptance of the procedure. Some unintended consequences were noted, however, including the potential effect of sterilization on the availability of traditional dog breeds in the communities. Overall, our study findings demonstrate that subsidized veterinary services provided over a regular and extended period of time benefit animal population demographics, health and welfare, and could have positive impacts on human well-being. The framework of community collaboration and long-term commitment developed through this program serves as a model for achieving common health goals among communities in need and veterinary service providers.

The empirical evidence base for the use of the HCR-20: A narrative review of study designs and transferability of results to clinical practice

The HCR-20, a widely used method of assessing and managing risk, relies on the structured professional judgement approach. This paper reports a narrative literature review of the HCR-20 studies to explore the applicability of the study results to the use of the HCR-20 in clinical practice. From a literature search using terms "HCR-20" and "HCR 20", 206 papers were included. Of studies using the HCR-20 version 2 (n = 191), 92% (n = 176) relied on variables based on scores derived by adding item scores, and 50% (n = 95) tested the HCR-20 using predictive validity methodology. Of the HCR-20 version 3 studies (n = 21), the "presence of risk factors" step was the most commonly examined (n = 18, 86%), but 2 of the 7 steps ("scenario planning" and "management") were not examined at all. Amongst those studies whose primary focus was on the HCR-20, 67% (n = 64/95) did so by assessing the predictive validity of the tool. Only one employed a design to test whether the use of the HCR-20 affected violence rates. The predominant study design provides support for the use of the HCR-20 as an actuarial tool, and there is limited empirical evidence in support of its effectiveness as a structured professional judgement approach to the assessment and management of the risk of violence.

Challenges in conducting epidemiological field studies evaluating associations between heat stress and renal health among workers in informal sectors: experiences from India

Well-designed Environmental Epidemiological Studies (EES) play a crucial role in quantifying the influence of environmental exposures and their associated risks on health in the wider population. They provide critical research evidence for identifying and developing interventions to avert adverse health consequences from those exposures. However, uncertainty and variability inherent to any field based EES could hinder the nature and magnitude of association between an exposure and health outcome. This is particularly pronounced in resource limited settings and resource-tight research projects. The present study evaluated the association between occupational heat stress and renal health among informal work sectors in India which had some significant challenges. Informal workers exposed to chronic occupational heat stress had significantly higher adverse renal health outcomes than the unexposed workers. Our field challenges included gaining access and permissions to conduct the study, participant recalls bias and attrition, accurately estimating exposures, confounding from causes of both exposure and disease, and to a large extent tight-funding. Though opportunities are abundant, we must ensure field conditions are optimized to attain study objectives. A keen understanding and sensitivity towards the cultural and work settings is essential for successful project completion. Based on our experiences, we provide strategies to adopt to improve fieldwork and provide recommendations to help overcome the field challenges and achieve better results for future EES studies in developing country settings.

Stakeholder perspectives and sustainability of an integrated care model for the prevention and management of obesity: the Childhood Obesity Research Demonstration (CORD) project

Although reliable strategies exist to promote healthy habits that reduce childhood obesity, the sustainability of these strategies remains an ongoing public health challenge. This study aimed to identify factors experienced in a large, multisite project aimed at reducing childhood obesity that might contribute to project sustainability. Hypothesized constructs underpinning sustainability included replicability, continuation of benefits, institutionalization, and community capacity. Key informants (n = 27) completed 60 min, in-depth interviews, which were audio recorded and transcribed. Transcripts were first coded using a combined deductive and inductive approach. Four major themes emerged (with numerous subthemes): developing partnerships, challenges to the sustainability of implemented programming, the importance of intervening in multiple settings, and ongoing implementation and evaluation strategies. Replicability of complex childhood obesity interventions is possible when there are strong partnerships. Benefits can continue to be conferred from programming, particularly when evidence-based strategies are used that employ best practices. Implementation is facilitated by institutionalization and policies that buffer challenges, such as staffing or leadership changes. Community capacity both enhances the sustainability of interventions and develops as a result of strengthening partnerships and policies that support childhood obesity programming.

Making community-supported agriculture accessible to low-income families: findings from the Farm Fresh Foods for Healthy Kids process evaluation

A randomized trial of Farm Fresh Foods for Healthy Kids (F3HK) was initiated across 4 states and 12 farms to test whether cost-offset community-supported agriculture (CO-CSA) could improve diet quality among children in low-income families. Intervention households purchased a 50% subsidized share of local produce and were invited to nine complimentary nutrition classes. The purpose of this study was to assess F3HK reach, dose, and fidelity via a mixed methods process evaluation. Screening and enrollment records indicated reach; study records and postlesson educator surveys tracked dose delivered; CSA pickup logs, lesson sign-in sheets, postseason participant surveys, and postlesson caregiver surveys assessed dose received; and coordinator audits and educator surveys tracked fidelity. Educator interviews contextualized findings. The results of this study were as follows. Reach: enrolled caregivers (n = 305) were older (p = .005) than eligible nonenrollees (n = 243) and more likely to be female (p < .001). Dose: mean CSA season was 21 weeks (interquartile range [IQR]: 19-23). Median CSA pickup was 88% of the weeks (IQR: 40-100). All sites offered each class at least once. Most adults (77%) and children (54%) attended at least one class; few attended all. Eighty-two percent of caregivers indicated that their household consumed most or all produce. Median lesson activity ratings were 5/5 ("very useful"). Fidelity: CSA locations functioned with integrity to project standards. Educators taught 92% of activities but frequently modified lesson order. This study demonstrates the feasibility of pairing a CO-CSA intervention with nutrition education across geographically dispersed sites. Greater integration of intervention elements and clearer allowance for site-level modifications, particularly for educational elements, may improve intervention dose and, ultimately, impact.

How does the British Soft Drink Association respond to media research reporting on the health consequences of sugary drinks?

Background

Sugar-sweetened beverages (SSBs) are the leading global source of added sugar intake and their consumption is associated with negative health outcomes, such as diabetes, cancers, cardiovascular diseases, and overall mortality. Despite consensus within the public health community about the need to reduce sugar intake, the non-alcoholic beverage industry engages in efforts to publicly undermine the evidence base surrounding the harmful effects of SSBs. There has been limited investigation of how SSB industry actors engage in public debates to challenge public health research and policy on SSBs. To address this gap, we thematically analyze the public comments and press releases of the British Soft Drinks Association (BSDA) since May 2014.

Results

A total of 175 news articles and 7 press releases were identified where the BSDA commented upon new SSB research in public settings. In these comments, four strategies were observed to undermine new research. First, the BSDA challenged study rigour and research design (n = 150). They challenged the policy implications of research by stating observational studies do not demonstrate causation, refuted data sources, questioned researcher motivations, and claimed research design did not account for confounding factors. Second, the BSDA positioned themselves as an altruistic public health partner (n = 52) intent on improving population-level nutrition citing their voluntary industry commitments. Third, the BSDA promoted concepts of safety that align with industry interests (n = 47). Lastly, the BSDA argued that the lifestyle of individual consumers should be the focus of public health interventions rather than the industry (n = 61).

Conclusion

The findings illustrate the BSDA reliance on arguments of causation to discredit research and avoid policy interventions. Given the attention by the BSDA regarding the purported lack of evidence of causation between SSBs and non-communicable diseases, it is imperative that members of the public health community try to educate policy makers about (a) the complex nature of causation; (b) that evidence in favour of public health interventions cannot, and do not, solely rely on causation studies; and (c) that public health must sometimes abide by the precautionary principle in instituting interventions.

Social Enterprise, Population Health and Sustainable Development Goal 3: A Public Health Viewpoint

Although there is no consensus on the definition of “social enterprises (SEs),” various scholars have agreed that SEs are “sustainable ventures that combine business principles with a passion for social impact.” Using a public health lens, this viewpoint paper attempts to discuss the potential role SEs might play in the achievement of sustainable population health and Sustainable Development Goal 3 (SDG 3): “Health for all at all ages.” Through their impact on social determinants of health (the conditions in which people are born, grow, work, and age), SEs have a potential to contribute to SDGs, specifically SDG 3. They can do so by acting on and modifying the economic, social and environmental challenges communities face, to help promote health and wellbeing and improve the quality of life among children, adolescents, working adults and elderly across countries, societies and generations. Social enterprises present an opportunity to engage business as partners in health promotion – which is yet to materialize in all societies globally.

The Stroman Effect: Participants in MEN Count, an HIV/STI Reduction Intervention for Unemployed and Unstably Housed Black Heterosexual Men, Define Its Most Successful Elements

Interventionists often prioritize quantitative evaluation criteria such as design (e.g., randomized controlled trials), delivery fidelity, and outcome effects to assess the success of an intervention. Albeit important, criteria such as these obscure other key metrics of success such as the role of the interactions between participants and intervention deliverers, or contextual factors that shape an intervention’s activities and outcomes. In line with advocacy to expand evaluation criteria for health interventions, we designed this qualitative study to examine how a subsample of Black men in MEN Count, an HIV/STI risk reduction and healthy relationship intervention with employment and housing stability case management for Black men in Washington, DC, defined the intervention’s success. We also examined the contextual factors that shaped participation in the study’s peer counseling sessions. We conducted structured interviews with 38 Black men, ages 18 to 60 years (M = 31.1, SD = 9.33) who completed at least one of three peer counseling sessions. Analyses highlighted three key themes: (a) the favorable impact of Mr. Stroman, the lead peer counselor, on participants’ willingness to participate in MEN Count and disclose their challenges—we dubbed this the “Stroman Effect”; (b) the importance of Black men intervention deliverers with relatable life experiences; and (c) how contextual factors such as the HIV/AIDS epidemic, needs for housing and employment services and safe spaces to talk about challenges, and absentee fathers shaped participation. We discuss the study’s implications for sustainable programs after funding ends and future multilevel health interventions to promote health equity for poor urban Black men.

Impact of Nonpharmacological Public Health Interventions on Epidemiological Parameters of COVID-19 Pandemic in India

Background Public health interventions are epidemiologically sound and cost-effective methods to control disease burden. Non-pharmacological public health interventions are the only mode to control diseases in the absence of medication. Objective To find the impact of public health interventions on the epidemiological indicators of disease progression. Methods This is a secondary data analysis done on COVID-19 data. The median doubling time and R0 were calculated for a rolling period of seven days. Interventions were scored from zero to three with an increasing level of stringency. Multivariate linear regression was performed to find the role of individual interventions on R0 and the median doubling time. Results The highest intervention score was reported in the lockdown phase, which gradually decreased to the lowest level of 22. The R0 values settled to a level of 1.25, and the median doubling time increased to 20 days at the end of the study. Public awareness and public health laws were found to be related to both R0 and the median doubling time in the pre-lockdown phase only. Conclusion The implementation of interventions at the ground level is one of the key factors in the success of public health interventions. Post implementation, poor effectiveness of many interventions is evident from the study. Further, studies related to the sequence of interventions are required to further analyze the poor effect of the interventions.

Effects of park-based interventions on health-related outcomes: A systematic review

Increasing use of parks for physical activity has been proposed for improving population health, including mental health. Interventions that aim to increase park use and park-based physical activity include place-based interventions (e.g., park renovations) and person-based interventions (e.g., park-based walking or exercise classes). Using adapted methods from the Community Guide, a systematic review (search period through September 2019) was conducted to evaluate the effectiveness of park-based interventions among adults. The primary outcomes of interest were health-related, including physical and mental health and moderate-to-vigorous physical activity. Twenty-seven studies that met review criteria were analyzed in 2019 and 2020. Seven person-based studies included generally small samples of specific populations and interventions involved mostly exercise programming in parks; all but one had an average quality rating as "high" and all had at least one statistically significant outcome. Of the 20 place-based interventions, 7 involved only 1 or 2 parks; however, 7 involved from 9 to 78 parks. Types of interventions were predominantly park renovations; only 5 involved park-based exercise programming. Most of the renovations were associated with increased park-level use and physical activity, however among those implementing programming, park-level effects were more modest. Less than half of the place-based intervention studies had an average quality rating of "high." The study of parks as sites for physical activity interventions is nascent. Hybrid methods that combine placed-based evaluations and cohort studies could inform how to best optimize policy, programming, design and management to promote health and well-being.

Evaluations of public health interventions produced by health technology assessment agencies: A mapping review and analysis by type and evidence content

OBJECTIVES

Health technology assessments (HTAs) have been suggested as a strategy to bridge the evidence-to-policy gap in public health. It is unclear to what extent HTAs have been prepared to assist decisions to implement public health interventions (PHIs). We aimed to describe the experience of HTA agencies by mapping, classifying, and analyzing the evidence content of HTAs of PHIs.

METHODS

We systematically searched databases of 35 HTA agencies from 18 countries for evaluations of PHIs between 2008-2018. Interventions were classified using the International Classification of Health Interventions and the evidence content analysed with the INAHTA Product-Type-mark checklist.

RESULTS

Only 1010 (9%) of HTAs were on PHIs. 500 (50%) publications targeted Body Systems and Functions, 302 (30%) Health-related Behaviours, 137 (14%) the Environment and 44 (4%) Activities and Participation Domains. Out of 734 publications perused, few met the criteria of full-HTAs (71;10%) or mini-HTAs (110;15%). Most were rapid reviews (420;57%). 72% of all reports came from only 6 countries.

CONCLUSION

HTAs on PHIs were uncommon relative to clinical interventions. HTAs on population-based PHIs were less comprehensive in quality and rigor of the evidence. Countries with more resources and mature HTA-systems had done the most evaluations. Exploring the experiences of forerunners could help overcome barriers to evaluations of PHIs and exploit the full potential of HTAs to promote evidence-based public health.

Implementing Health Apps for Digital Public Health - An Implementation Science Approach Adopting the Consolidated Framework for Implementation Research

Apps are becoming an increasingly important component of modern Public Health and health care. However, successful implementation of apps does not come without challenges. The Consolidated Framework for Implementation Research (CFIR) provides a central typology to support the development of implementation theories and the examination of what works where and why in different contexts. The framework offers a reasonable structure for managing complex, interacting, multi-level, and transient states of constructs in the real world: It draws on constructs from other implementation theories and might be used to conduct formative evaluations or build a common body of knowledge for implementation thru various studies and settings. In a synthesis of the original English language text describing the CFIR, an attempt was made to break the constructs down into the shortest possible concise descriptions for the implementation of health care apps in a structured, selective process. The listed key constructs should help to develop successful implementation plans and models for health apps and show the complexity of a successful implementation. As a perspective article, the aim of the current piece is to present a viewpoint on using the CFIR as a potential support for implementing health apps.

Implementation of evidence-based health promotion and disease prevention interventions: theoretical and practical implications of the concept of transferability for decision-making and the transfer process

Evidence-based health promotion and disease prevention require incorporating evidence of the effectiveness of interventions into policy and practice. With the entry into force of the German Act to Strengthen Health Promotion and Prevention (PrävG), interventions that take place in people’s everyday living environments have gained in importance. Decision-makers need to assess whether an evidence-based intervention is transferable to their specific target context. The Federal Centre for Health Education (BZgA) recommends that transferability of an intervention should be clarified before any decision to implement it. Furthermore, transferability needs to be finally determined after an evaluation in the target context. In this article, we elaborate on theoretical and practical implications of the concept of transferability for health promotion and disease prevention based on the Population–Intervention–Environment–Transfer Models of Transferability (PIET-T). We discuss how decision-makers can anticipate transferability prior to the intervention transfer with the help of transferability criteria and how they can take transferability into account in the further process. This includes the steps of the analysis of a health problem and identification of effective interventions, the steps of the initial transferability assessment and identification of the need for adaptation, and the steps of the implementation and evaluation. Considering transferability is a complex task that comes with challenges. But it offers opportunities to select a suitable intervention for a target context and, in the transfer process, to understand the conditions under which the intervention works in this context. This knowledge helps to establish an evidence base, which is practically relevant.

Adherence Is More Than Just Being Present: Example of a Lay-Led Home-Based Programme with Physical Exercise, Nutritional Improvement and Social Support, in Prefrail and Frail Community-Dwelling Older Adults

BACKGROUND

Little is known about the implementation of lifestyle interventions in frail, community-dwelling people. This study highlights different domains of adherence to explain an effectively delivered home-based intervention.

METHODS

Eighty prefrail and frail persons (≥65 years) participated in a physical training, nutritional, and social support intervention over 24 weeks. A detailed log book was kept for comprehensive documentation in order to assess adherence and further organizational, exercise, and nutritional parameters.

RESULTS

Participants reached an adherence rate (performed home visits/number of planned visits) of 84.0/80.5% from week 1-12/13-24. Out of those, 59% carried out ≥75% of the offered visits. Older age was associated with a higher adherence rate. A mean of 1.5 (0.6) visits/week (2 were planned) were realized lasting for a mean of 1.5 (0.9) hours (154% of the planned duration). Per visit, 1.2 (0.6) circuits of strength training were performed (60.5% of the planned value) and 0.5 (0.3) nutritional interventions (47%). After twelve months, 4.2% still carried out the home visits regularly and 25.0% occasionally.

CONCLUSION

Adherence is much more than "being there". Adherence rate and category are limited parameters to describe the implementation of a complex lifestyle intervention, therefore a comprehensive documentation is needed.

Psychosocial well-being of brain cancer patients and support persons: A mapping review of study types over time

INTRODUCTION

This review examined the: (1) number of publications exploring psychosocial outcomes of adults with brain cancer and/or support persons between 1999 and 2019 and whether there has been a change in the type of research over time; and (2) proportion of intervention studies meeting Cochrane Effective Practice and Organisation of Care (EPOC) research design criteria.

METHODS

Embase, The Cochrane Library, Medline and PsycINFO databases were electronically searched January 1999 to December 2019. Articles were examined against inclusion/exclusion criteria and coded into measurement, descriptive or intervention categories. Intervention studies were assessed against the EPOC design criteria.

RESULTS

220 eligible publications were identified. The number of total publications significantly increased by an average of 1 each year (95%CI = 0.7-1.3; p < 0.001). There was no significant change in the proportion of publications by study type across three time periods. Descriptive research represented the majority within each time period. Of the 17 intervention studies, only 7(41%) met EPOC design criteria.

CONCLUSIONS

Published literature on brain cancer psychosocial outcomes has increased significantly. However, descriptive research dominates research output. To increase high-level knowledge that can guide psychosocial care of people with brain cancer, there is a need to undertake methodologically rigorous intervention trials.

Mechanisms of scaling up: combining a realist perspective and systems analysis to understand successfully scaled interventions

Background

Sustainable shifts in population behaviours require system-level implementation and embeddedness of large-scale health interventions. This paper aims to understand how different contexts of scaling up interventions affect mechanisms to produce intended and unintended scale up outcomes.

Methods

A mixed method study combining a realist perspective and systems analysis (causal loop diagrams) of scaled-up physical activity and/or nutrition interventions implemented at a state/national level in Australia (2010–18). The study involved four distinct phases: Phase 1 expert consultation, database and grey literature searches to identify scaled-up interventions; Phase 2 generating initial Context-Mechanism-Outcome configurations (CMOs) from the WHO ExpandNet framework for scaling up; Phase 3 testing and refining CMOs via online surveys and realist interviews with academics, government and non-government organisations (NGOs) involved in scale up of selected interventions (Phase 1); and Phase 4 generating cross-case mid-range theories represented in systems models of scaling up; validated by member checking. Descriptive statistics were reported for online survey data and realist analysis for interview data.

Results

Seven interventions were analysed, targeting nutrition (n = 1), physical activity (n = 1), or a combination (n = 5). Twenty-six participants completed surveys; 19 completed interviews. Sixty-three CMO pathways underpinned successful scale up, reflecting 36 scale up contexts, 8 key outcomes; linked via 53 commonly occurring mechanisms. All five WHO framework domains were represented in the systems models. Most CMO pathways included ‘intervention attributes’ and led to outcomes ‘community sustainability/embeddedness’ and ‘stakeholder buy-in/perceived value’. Irrespective of interventions being scaled in similar contexts (e.g., having political favourability); mechanisms still led to both intended and unintended scale up outcomes (e.g., increased or reduced sustainability).

Conclusion

This paper provides the first evidence for mechanisms underpinning outcomes required for successful scale up of state or nationally delivered interventions. Our findings challenge current prerequisites for effective scaling suggesting other conditions may be necessary. Future scale up approaches that plan for complexity and encourage iterative adaptation throughout, may enhance scale up outcomes. Current linear, context-to-outcome depictions of scale up oversimplify what is a clearly a complex interaction between perceptions, worldviews and goals of those involved. Mechanisms identified in this study could potentially be leveraged during future scale up efforts, to positively influence intervention scalability and sustainability.

Development and process evaluation of a motor activity program for people with profound intellectual and multiple disabilities

Background

The support of people with profound intellectual and multiple disabilities (PIMD) rarely focused on motor activity, which might have negative consequences for the quality of life of these people. Evidence-based motor activity programs that present individually tailored and structural motor activity for these people are, regretfully, lacking. This study developed such a program for these people and evaluated the implementation process.

Methods

The motor activity program is developed in accordance with the theoretical premises of the educational program and consists of four methodological steps in which the content is individually filled with: motor activity structurally embedded within the activities of daily living, and 3–5 motor activities aimed at a specific goal, which is evaluated. Program delivery consisted of a manual, explanation to the teams, and coaching of one contact person per participant (n = 9). Process evaluation included the delivered fidelity, dose, reach, and adaptations made during the program. In addition, mechanisms of impact and the influence of contextual factors were evaluated. Data collection included researcher logbooks, individual program content, and staff reports.

Results

The intended fidelity, dose, and reach were not obtained in most participants. Content has been made explicit for seven participants, but only in one participant all critical steps in implementation were performed as intended, though later in time. In three participants, previously offered motor activities were described within the weekly program, but without all activities having a clear link with the goal set. It is showed that the core elements of the program were affected with the conceived implementation plan. The time schedule, critical elements in implementation and program content were influenced by a lack of conditions such as professionals’ motivation and responsibility, methodical working, interdisciplinarity and continuity in staff.

Conclusions

The results suggest that the implementation might be improved in case more attention is paid to the organizational conditions and implementation structure. The findings led to substantial changes in the implementation strategy. This study underlines the importance of process evaluation prior to testing for effectiveness.

Mental model-based repeated multifaceted (MRM) intervention design: a conceptual framework for improving preventive health behaviors and outcomes

Objective

Field interventions employed to improve preventive health behaviors and outcomes generally use well-established approaches; however, recent studies have reported that health education and promotional interventions have little to no impact on health behaviors, especially in low- and middle-income countries. We aimed to develop a conceptual framework to improve intervention designs that would internalize these concerns and limitations.

Results

We identified three major experimental design- and implementation-related concerns associated with mental models, including the balance between the treatment and control groups, the treatment group’s willingness to adopt suggested behaviors, and the type, length, frequency, intensity, and sequence of treatments. To minimize the influence of these aspects of an experimental design, we proposed a mental model-based repeated multifaceted (MRM) intervention design framework, which represents a supportive intervention design for the improvement of health education and promotional programs. The framework offers a step-by-step method that can be used for experimental and treatment design and outcome analysis, and that addresses potential implementation challenges.

Exploring influences on evaluation practice: a case study of a national physical activity programme

BACKGROUND

Interventions to improve physical activity behaviour are a core part of public health policy and practice. It is essential that we evaluate these interventions and use the evidence to inform decisions to improve population health. Evaluation of 'real-world' interventions provide an opportunity to generate practice-relevant evidence, however these interventions are difficult to evaluate. Various guidelines have been developed to facilitate evaluation, but evidence about their effectiveness in practice is limited. To explore influences on evaluation practice in an applied context, we conducted a case study of Sport England's 'Get Healthy Get Active' (GHGA) programme. This was a national programme that funded 33 projects that were delivered and evaluated across England. The programme was chosen as it was designed to generate evidence on the role of sport in increasing physical activity and improving health. The study aimed to explore and appraise whether strategies intended to facilitate project evaluation, including funder requirements to use a standardised evaluation framework and specific data collection methods, were effective in generating evidence that enabled the programme to meet its aims.

METHODS

We applied a collective case study design involving 35 semi-structured interviews, and documentary analysis of multiple sources of evidence from 23 physical activity projects funded by GHGA. We applied thematic and framework analysis. We developed a logic model and mapped actual outcomes against intended outcomes. A narrative synthesis is provided. We discuss implications for the effective commissioning and evaluation of public health interventions.

RESULTS

We identified five main themes of influences on evaluation practices that can act as barriers and facilitators to good practice: programme and project design; evaluation design; partnerships; resources; and organisational structures and systems. These influences are context-specific and operate through a complex set of interactions.

CONCLUSION

Developing a better understanding of how influences on evaluation practice can act as facilitators or barriers is vital to help close current gaps in the evidence-based practice cycle. Critically, organisational structures and systems are needed to facilitate collaborative decision making; integration of projects and evaluation across partners organisations; transfer of knowldege and insights between stakeholders; and more rapid feedback and dissemination.

Implementing best available evidence into practice for incontinence-associated dermatitis in Australia: A multisite multimethod study protocol

AIMS

Incontinence-associated dermatitis (IAD) is an insidious and under-reported hospital-acquired complication which substantially impacts on patients' quality of life. A published international guideline and the Ghent Global IAD Categorisation Tool (GLOBIAD) outline the best available evidence for the optimal management of IAD. This study aims to implement theguideline and the GLOBIAD tool and evaluate the effect on IAD occurrences and sacral pressure injuries as well as patient, clinician and cost-effectiveness outcomes.

MATERIALS AND METHODS

The study will employ a multi-method design across six hospitals in five health districts in Australia, and will be conducted in three phases (pre-implementation, implementation and post-implementation) over 19 months. Data collection will involve IAD and pressure injury prevalence audits for patient hospital admissions, focus groups with, and surveys of, clinicians, patient interviews, and collection of the cost of IAD hospital care and patient-related outcomes including quality of life. Eligible participants will be hospitalised adults over 18 years of age experiencing incontinence, and clinicians working in the study wards will be invited to participate in focus groups and surveys.

CONCLUSION

The implementation of health district-wide evidence-based practices for IAD using a translational research approach that engages key stakeholders will allow the standardisation of IAD care that can potentially be applicable to a range of settings. Knowledge gained will inform future practice change in patient care and health service delivery and improve the quality of care for patients with IAD. Support at the hospital, state and national levels, coupled with a refined stakeholder-inclusive strategy, will enhance this project's success, sustainability and scalability beyond this existing project.

Promoting Intersectoral Collaboration Through the Evaluations of Public Health Interventions: Insights From Key Informants in 6 European Countries

BACKGROUND

Intersectoral collaboration is critical to the successful implementation of many public health interventions (PHIs). Little attention has been paid to whether and how processes at the stage of evaluation can promote intersectoral collaboration. The objective of this study was to examine European experiences and views on whether and how the evaluation of PHIs promote intersectoral collaboration.

METHODS

A qualitative study design was used. We conducted semi-structured interviews with 15 individuals centrally involved in the evaluation of PHIs in 6 European countries (Austria, Denmark, England, Germany, Norway, and Switzerland). Questions pertained to current processes for evaluating PHIs in the country and current and potential strategies for promoting intersectoral collaboration. Transcripts were analyzed using thematic analysis to identify key themes responding to our primary objective.

RESULTS

Experiences with promoting intersectoral collaboration through the evaluation of PHIs could be summarized in 4 themes: (1) Early involvement of non-health sectors in the evaluative process and inclusion of non-health benefits can promote intersectoral collaboration, but should be combined with greater influence of these sectors in shaping PHIs; (2) Harmonization of methodological approaches may enable comparison of results and facilitate intersectoral collaboration, but should not be an overriding goal; (3) Involvement in health impact assessments (HIAs) can promote intersectoral collaboration, but needs to be incentivized and be conducted without putting overwhelming demands on non-health sectors; (4) A designated body for evaluating PHIs may promote intersectoral collaboration, but its design needs to take account of realities of policy-making.

CONCLUSION

The full potential for promoting intersectoral collaboration through the evaluation of PHIs appears currently unrealized in the settings we studied. To further promote intersectoral collaboration, evaluators and decision-makers may consider the full range of strategies characterized in this study. This may be most effective if the strategies are deployed so that they reinforce each other, value outcomes beyond health, and are tailored to maximize political priority for PHIs across sectors.

Health vs. wealth: Employer, employee and policy-maker perspectives on occupational heat stress across multiple European industries

Successful implementation of cooling strategies obviously depends on identifying effective interventions, but in industrial settings, it is equally important to consider feasibility and economic viability. Many cooling interventions are available, but the decision processes affecting adoption by end-users are not well elucidated. We therefore arranged two series of meetings with stakeholders to identify knowledge gaps, receive feedback on proposed cooling interventions, and discuss factors affecting implementation of heat-health interventions. This included four meetings attended by employers, employees, and health and safety officers (n = 41), and three meetings attended primarily by policy makers (n = 74), with feedback obtained via qualitative and quantitative questionnaires and focus group discussions. On a 10-point scale, both employers and employees valued worker safety (9.1 ± 1.8; mean±SD) and health (8.5 ± 1.9) as more important than protecting company profits (6.3 ± 2.3). Of the respondents, 41% were unaware of any cooling strategies at their company and of those who were aware, only 30% thought the interventions were effective. Following presentation of proposed interventions, the respondents rated "facilitated hydration", "optimization of clothing/protective equipment", and "rescheduling of work tasks" as the top-three preferred solutions. The main barriers for adopting cooling interventions were cost, feasibility, employer perceptions, and legislation. In conclusion, preventing negative health and safety effects was deemed to be more important than preventing productivity loss. Regardless of work sector or occupation, both health and wealth were emphasized as important parameters and considered as somewhat interrelated. However, a large fraction of the European worker force lacks information on effective measures to mitigate occupational heat stress.

Neuropsychological rehabilitation interventions for people with an acquired brain injury. A protocol for a systematic review of economic evaluation

Background: New emerging evidence has demonstrated the need for effective interventions to help people living with an acquired brain injury (ABI). Evidence on cost-effectiveness, which can help inform use of limited resources, is scarce in this area and therefore the purpose of this systematic review is to critically appraise and consolidate the current evidence on economic evaluations of ABI rehabilitation interventions. Methods: Systematic review methodology will be applied to identify, select and extract data from published economic evaluation studies (trial-based, non-trial based, simulation-based, decision model and trial-based model economic evaluations) of ABI treatment interventions in adults. A systematic literature search will be conducted on the following electronic databases: EMBASE, Econlit, CINAHL, Medline, the National Health Service Economic Evaluation Database and PsyclNFO. This review will only include cost-effectiveness analysis studies (e.g., cost per life year gained), cost-benefit and cost minimisation analyses in which the designs were randomised controlled trials (RCTs), non-RCT studies, cost-utility analyses (e.g., cost per quality-adjusted life year (QALY) gained or cost per disability-adjusted life year averted), cohort studies, and modelling studies. Only studies that were published in the english language, associated with adults who have an ABI will be included. There will be no restrictions on perspective, sample size, country, follow-up duration or setting. The search strategy terms will include the following: acquired brain injury, brain*; cost*; or cost-benefit analysis*. Following data extraction, a narrative summary and tables will be used to summarize the characteristics and results of included studies. Discussion: The findings from this review will be beneficial to health policy decision makers when examining the evidence of economic evaluations in this field. In addition, it is anticipated that this review will identify gaps in the current economic literature to inform future-related research.

The impact of gardening on nutrition and physical health outcomes: a systematic review and meta-analysis

Community gardening has been widely recognized as a multicomponent approach that has affected a broad range of health and well-being outcomes. The objective of this study was to investigate the association between community gardening and nutrition and physical health among adults. A systematic review and meta-analysis were conducted. Five electronic databases were searched systematically. Quality of included studies was appraised by several quality assessment tools related to the study design of each included article. Evidence from 19 articles was included (14 cross-sectional studies, 4 quasi-experimental studies and 1 case-control study). Although the majority of included studies appeared to have moderate quality, there existed weaknesses in the methods used, including low response rate and lack of confounder controls. Due to diversity in the measurement units, only body mass index (BMI) data could be pooled to perform meta-analysis. The results suggest that gardening had a significantly positive effect on BMI reduction. Subgroup analysis showed that quasi-experimental and case-control studies produced greater pooled effect size than those of cross-sectional design. Funnel plot and Egger's test showed no significant evidence of publication bias. As robust evidence for the effect of community gardening on BMI reduction was found, this intervention should be integrated in health promoting policy to improve population health.

A framework for identifying and mitigating the equity harms of COVID-19 policy interventions

BACKGROUND

Coronavirus disease 2019 (COVID-19) is a global pandemic. Governments have implemented combinations of "lockdown" measures of various stringencies, including school and workplace closures, cancellations of public events, and restrictions on internal and external movements. These policy interventions are an attempt to shield high-risk individuals and to prevent overwhelming countries' healthcare systems, or, colloquially, "flatten the curve." However, these policy interventions may come with physical and psychological health harms, group and social harms, and opportunity costs. These policies may particularly affect vulnerable populations and not only exacerbate pre-existing inequities but also generate new ones.

METHODS

We developed a conceptual framework to identify and categorize adverse effects of COVID-19 lockdown measures. We based our framework on Lorenc and Oliver's framework for the adverse effects of public health interventions and the PROGRESS-Plus equity framework. To test its application, we purposively sampled COVID-19 policy examples from around the world and evaluated them for the potential physical, psychological, and social harms, as well as opportunity costs, in each of the PROGRESS-Plus equity domains: Place of residence, Race/ethnicity, Occupation, Gender/sex, Religion, Education, Socioeconomic status, Social capital, Plus (age, and disability).

RESULTS

We found examples of inequitably distributed adverse effects for each COVID-19 lockdown policy example, stratified by a low- or middle-income country and high-income country, in every PROGRESS-Plus equity domain. We identified the known policy interventions intended to mitigate some of these adverse effects. The same harms (anxiety, depression, food insecurity, loneliness, stigma, violence) appear to be repeated across many groups and are exacerbated by several COVID-19 policy interventions.

CONCLUSION

Our conceptual framework highlights the fact that COVID-19 policy interventions can generate or exacerbate interactive and multiplicative equity harms. Applying this framework can help in three ways: (1) identifying the areas where a policy intervention may generate inequitable adverse effects; (2) mitigating the policy and practice interventions by facilitating the systematic examination of relevant evidence; and (3) planning for lifting COVID-19 lockdowns and policy interventions around the world.

Evidence for action: a One Health learning platform on interventions to tackle antimicrobial resistance

Improving evidence for action is crucial to tackle antimicrobial resistance. The number of interventions for antimicrobial resistance is increasing but current research has major limitations in terms of efforts, methods, scope, quality, and reporting. Moving the agenda forwards requires an improved understanding of the diversity of interventions, their feasibility and cost-benefit, the implementation factors that shape and underpin their effectiveness, and the ways in which individual interventions might interact synergistically or antagonistically to influence actions against antimicrobial resistance in different contexts. Within the efforts to strengthen the global governance of antimicrobial resistance, we advocate for the creation of an international One Health platform for online learning. The platform will synthesise the evidence for actions on antimicrobial resistance into a fully accessible database; generate new scientific insights into the design, implementation, evaluation, and reporting of the broad range of interventions relevant to addressing antimicrobial resistance; and ultimately contribute to the goal of building societal resilience to this central challenge of the 21st century.

Measuring the Efficacy of a Pilot Public Health Intervention for Engaging Communities of Puerto Rico to Rapidly Write Hurricane Protection Plans

OBJECTIVE

The efficacy is measured for a public health intervention related to community-based planning for population protection measures (PPMs; ie, shelter-in-place and evacuation).

DESIGN

This is a mixed (qualitative and quantitative) prospective study of intervention efficacy, measured in terms of usability related to effectiveness, efficiency, satisfaction, and degree of community engagement.

SETTING

Two municipalities in the Commonwealth of Puerto Rico are included.

PARTICIPANTS

Community members consisting of individuals; traditional leaders; federal, territorial, and municipal emergency managers; municipal mayors; National Guard; territorial departments of education, health, housing, public works, and transportation; health care; police; Emergency Medical Services; faith-based organizations; nongovernmental organizations (NGOs); and the private sector.

INTERVENTION

The intervention included four community convenings: one for risk communication; two for plan-writing; and one tabletop exercise (TTX). This study analyzed data collected from the project work plan; participant rosters; participant surveys; workshop outputs; and focus group interviews.

MAIN OUTCOME MEASURES

Efficacy was measured in terms of ISO 9241-11, an international standard for usability that includes effectiveness, efficiency, user satisfaction, and "freedom from risk" among users. Degree of engagement was considered an indicator of "freedom from risk," measurable through workshop attendance.

RESULTS

Two separate communities drafted and exercised ~60-page-long population protection plans, each within 14.5 hours. Plan-writing workshops completed 100% of plan objectives and activities. Efficiency rates were nearly the same in both communities. Interviews and surveys indicated high degrees of community satisfaction. Engagement was consistent among community members and variable among governmental officials.

CONCLUSIONS

Frontline communities have successfully demonstrated the ability to understand the environmental health hazards in their own community; rapidly write consensus-based plans for PPMs; participate in an objective-based TTX; and perform these activities in a bi-lingual setting. This intervention appears to be efficacious for public use in the rapid development of community-based PPMs.

Neuropsychological rehabilitation interventions for people with an acquired brain injury and their caregivers. A protocol for a systematic review of economic evaluation

Personalized early detection and prevention of breast cancer: ENVISION consensus statement

The European Collaborative on Personalized Early Detection and Prevention of Breast Cancer (ENVISION) brings together several international research consortia working on different aspects of the personalized early detection and prevention of breast cancer. In a consensus conference held in 2019, the members of this network identified research areas requiring development to enable evidence-based personalized interventions that might improve the benefits and reduce the harms of existing breast cancer screening and prevention programmes. The priority areas identified were: 1) breast cancer subtype-specific risk assessment tools applicable to women of all ancestries; 2) intermediate surrogate markers of response to preventive measures; 3) novel non-surgical preventive measures to reduce the incidence of breast cancer of poor prognosis; and 4) hybrid effectiveness-implementation research combined with modelling studies to evaluate the long-term population outcomes of risk-based early detection strategies. The implementation of such programmes would require health-care systems to be open to learning and adapting, the engagement of a diverse range of stakeholders and tailoring to societal norms and values, while also addressing the ethical and legal issues. In this Consensus Statement, we discuss the current state of breast cancer risk prediction, risk-stratified prevention and early detection strategies, and their implementation. Throughout, we highlight priorities for advancing each of these areas.

Health-promoting and preventive interventions for community-dwelling older people published from inception to 2019: a scoping review to guide decision making in a Swedish municipality context

Background

Despite the promising evidence of health-promoting and preventive interventions for maintaining health among older people, not all interventions can be implemented due to limited resources. Due to the variation of content in the interventions and the breadth of outcomes used to evaluate effects in such interventions, comparisons are difficult and the choice of which interventions to implement is challenging. Therefore, more information, beyond effects, is needed to guide decision-makers. The aim of this review was to investigate, to what degree factors important for decision-making have been reported in the existing health-promoting and preventive interventions literature for community-dwelling older people in the Nordic countries.

Methods

This review was guided by the PRISMA-ScR checklist (Preferred Reporting Items for Systematic reviews and Meta-Analysis extension for Scoping Reviews), the methodological steps for scoping reviews described in the Arksey and O′Malley’s framework, and the Medical Research Council’s (MRC) guidance on complex interventions. Eligible studies for inclusion were randomised controlled trials (RCTs) concerning health promotion or primary prevention for community-dwelling older people implemented in the Nordic countries. Additionally, all included RCTs were searched for related papers that were reporting on additional factors. Eligible studies were searched in seven databases: PubMed, SCOPUS, CINAHL, Academic Search Elite, PsycINFO, SocINDEX, and SPORTDiscus.

Results

Eighty-two studies met the inclusion criteria (twenty-seven unique studies and fifty-five related studies). Twelve studies focused on fall prevention, eleven had a health-promoting approach, and four studies focused on preventing disability. All interventions, besides one, reported positive effects on at least one health outcome. Three studies reported data on cost-effectiveness, three on experiences of participants and two conducted feasibility studies. Only one intervention, reported information on all seven factors.

Conclusions

All identified studies on health-promoting and preventive interventions for older people evaluated in the Nordic countries report positive effects although the magnitude of effects and number of follow-ups differed substantially. Overall, there was a general lack of studies on feasibility, cost-effectiveness, and experiences of participants, thus, limiting the basis for decision making. Considering all reported factors, promising candidates to be recommended for implementation in a Nordic municipality context are ‘Senior meetings’, ‘preventive home visits’ and ‘exercise interventions’ on its own or combined with other components.

Implementation fidelity and acceptability of an intervention to improve vaccination uptake and child health in rural India: a mixed methods evaluation of a pilot cluster randomized controlled trial

Background

The Tika Vaani intervention, an initiative to improve basic health knowledge and empower beneficiaries to improve vaccination uptake and child health for underserved rural populations in India, was assessed in a pilot cluster randomized trial. The intervention was delivered through two strategies: mHealth (using mobile phones to send vaccination reminders and audio-based messages) and community mobilization (face-to-face meetings) in rural Indian villages from January to September 2018. We assessed acceptability and implementation fidelity to determine whether the intervention delivered in the pilot trial can be implemented at a larger scale.

Methods

We adapted the Conceptual Framework for implementation fidelity to assess acceptability and fidelity of the pilot interventions using a mixed methods design. Quantitative data sources include a structured checklist, household surveys, and mobile phone call patterns. Qualitative data came from field observations, intervention records, semi-structured interviews and focus groups with project recipients and implementers. Quantitative analyses assessed whether activities were implemented as planned, using descriptive statistics to describe participant characteristics and the percentage distribution of activities. Qualitative data were analyzed using content analysis and in the light of the implementation fidelity model to explore moderating factors and to determine how well the intervention was received.

Results

Findings demonstrated high (86.7%) implementation fidelity. A total of 94% of the target population benefited from the intervention by participating in a face-to-face group meeting or via mobile phone. The participants felt that the strategies were useful means for obtaining information. The clarity of the intervention theory, the motivation, and commitment of the implementers as well as the periodic meetings of the supervisors largely explain the high level of fidelity obtained. Geographic distance, access to a mobile phone, level of education, and gender norms are contextual factors that contributed to heterogeneity in participation.

Conclusions

Although the intervention was evaluated in the context of a randomized trial that could explain the high level of fidelity obtained, this evaluation provides confirmatory evidence that the results of the study reflect the underlying theory. The mobile platform coupled with community mobilization was well-received by the participants and could be a useful way to improve health knowledge and change behavior.

Combining Effect and Process Evaluation on European Preschool Children's Snacking Behavior in a Kindergarten-Based, Family-Involved Cluster Randomized Controlled Trial: The ToyBox Study

This study aimed at (1) studying the effect of the standardized ToyBox intervention on European preschoolers' snacking behavior, and (2) studying whether a higher process evaluation score from teachers and parents/caregivers was associated with a more positive result for preschoolers' snack intake. A sample of 4970 preschoolers (51.4% boys, 4.74 ± 0.44 years) from six European countries provided information on snack intake with the use of a Food Frequency Questionnaire. To investigate the effect of the intervention, multilevel repeated measures analyses were executed for the total sample and the six country-specific samples. Furthermore, questionnaires to measure process evaluation were used to compute a total process evaluation score for teachers and parents/caregivers. No significant intervention effects on preschoolers' snack intake were found (all p > 0.003). In general, no different effects of the intervention on snack intake were found according to kindergarten teachers' and parents'/caregivers' process evaluation scores. The lack of effects could be due to limited intervention duration and dose. To induce larger effects on preschoolers' snack intake, a less standardized intervention which is more tailored to the local needs might be needed.

Social enterprises' impact on older people's health and wellbeing: exploring Scottish experiences

The global aging demographic is putting pressure on state-delivered health and social care services. As the austerity agenda in the UK cuts state-funded service provision for older people despite increasing demand, social enterprise has become a politically and economically attractive model for the sustainable delivery of some public services. Yet little is known about the impact of social enterprise on the health and wellbeing of older people. In this paper we address this gap in understanding and consider social enterprise activities as complex public health-promoting interventions. Our study aimed to understand what impact social enterprise activities had on the health and wellbeing of participants aged over 50, and also how that impact was created. To achieve this, we conducted qualitative semi-structured interviews with a sample (n = 43) of staff, volunteers, clients and carers aged over 50 who were involved in activities delivered by three social enterprises. Using a thematic analysis to explore manifest and latent themes, two antecedents of subjective younger age emerged explaining how benefit was created, namely downward social comparison and identity. The social enterprise activities we studied benefited participants' health and wellbeing, impacting positively on participants' sense of purpose, social support, connectedness and inclusion. These health and wellbeing benefits can be considered as outcomes of complex public health interventions for older people, and we relate these outcomes to beneficial conditions within the intermediary social determinants of health. We conclude by discussing the future impact of social enterprise activities and current UK policy on the structural determinants of health.

Reassessing the Ethics of Molecular HIV Surveillance in the Era of Cluster Detection and Response: Toward HIV Data Justice

In the United States, clinical HIV data reported to surveillance systems operated by jurisdictional departments of public health are re-used for epidemiology and prevention. In 2018, all jurisdictions began using HIV genetic sequence data from clinical drug resistance tests to identify people living with HIV in "clusters" of others with genetically similar strains. This is called "molecular HIV surveillance" (MHS). In 2019, "cluster detection and response" (CDR) programs that re-use MHS data became the "fourth pillar" of the national HIV strategy. Public health re-uses of HIV data are done without consent and are a source of concern among stakeholders. This article presents three cases that illuminate bioethical challenges associated with re-uses of clinical HIV data for public health. We focus on evidence-base, risk-benefit ratio, determining directionality of HIV transmission, consent, and ethical re-use. The conclusion offers strategies for "HIV data justice." The essay contributes to a "bioethics of the oppressed."

Piloting a culturally appropriate, localised diabetes prevention program for young Aboriginal people in a remote town

Lifestyle changes are central to preventing type 2 diabetes. Embarking upon and sustaining change is challenging, and translation of prevention approaches into a wider range of real-world settings is needed. In this study, a locally adapted community-led diabetes prevention program with local young Aboriginal facilitators was created and trialled through the Derby Aboriginal Health Service (DAHS). The 8-week program highlighted causes and consequences of diabetes, incorporated physical activity and healthy eating topics with a focus on practical activities, and included stress management to support healthy lifestyles. Ten Aboriginal women and men aged 18-38 years participated in the pilot program. The program was found to be acceptable and appropriate, and other community members and organisations expressed interest in future participation. Participants reported that they gained important new knowledge and made changes in behaviours including shopping choices, portioning and soft drink consumption. Limitations included participant recruitment and attendance difficulties, which were attributed to program timing and competing demands. While this program was designed to be sustainable, and there were indications of feasibility, resource constraints impeded its integration into routine primary health care. Prevention of diabetes is a high priority for DAHS, and this program, with appropriate resources, provides a basis for ongoing practical prevention strategies.

Public health programmes to promote mental health in young people: a systematic integrative review protocol

INTRODUCTION

In light of the ever-growing mental health disease burden among young people worldwide, we aim to systematically review the global literature to identify the public health programmes targeted at promoting mental health and well-being in young people, the reported/anticipated mental health-related outcomes of the implemented public health programmes and the reported facilitators and barriers in relation to the implementation of those public health programmes.

METHODS AND ANALYSIS

A comprehensive literature search will be carried out in the following electronic bibliographic databases: MEDLINE, EMBASE, PsycINFO, Scopus, ASSIA, Web of Science, Global Health, AMED, Health Source and The Cochrane Library. Further, a manual search of the reference lists of eligible studies and reviews will be carried out. The search strategy will include combinations of three key blocks of terms, namely: 'young people', 'mental health' and 'public health programme', using database-specific subject headings and text words. Two reviewers will independently screen, assess data quality and extract data for synthesis. Disagreements at any stage will be resolved by consensus with the involvement of a third reviewer. Given the anticipated methodological pluralism of the potential eligible studies, we will provide a narrative synthesis of the findings on public health programmes aimed at promoting the mental health and well-being of young people according to identified thematic areas. Furthermore, a narrative synthesis of the reported facilitators and barriers in relation to the implementation of public health programmes will be provided.

ETHICS AND DISSEMINATION

Given that the review findings will be focused on understanding the breadth and depth of the global research into public health programmes to promote mental health in young people with a particular emphasis on the facilitators and barriers of programmatic implementation, the findings will be of great value to inform future interventions, programmes and approaches to promote mental health and well-being of young people worldwide.

Co-construction of the family-focused support conversation: a participatory learning and action research study to implement support for family members whose relatives are being discharged for end-of-life care at home or in a nursing home

BACKGROUND

Many people move in and out of hospital in the last few weeks of life. These care transitions can be distressing for family members because they signify the deterioration and impending death of their ill relative and forthcoming family bereavement. Whilst there is evidence about psychosocial support for family members providing end-of-life care at home, there is limited evidence about how this can be provided in acute hospitals during care transitions. Consequently, family members report a lack of support from hospital-based healthcare professionals.

METHODS

The aim of the study was to implement research evidence for family support at the end-of-life in acute hospital care. Informed by Participatory Learning and Action Research and Normalization Process Theory (NPT) we co-designed a context-specific intervention, the Family-Focused Support Conversation, from a detailed review of research evidence. We undertook a pilot implementation in three acute hospital Trusts in England to assess the potential for the intervention to be used in clinical practice. Pilot implementation was undertaken during a three-month period by seven clinical co-researchers - nurses and occupational therapists in hospital specialist palliative care services. Implementation was evaluated through data comprised of reflective records of intervention delivery (n = 22), in-depth records of telephone implementation support meetings between research team members and co-researchers (n = 3), and in-depth evaluation meetings (n = 2). Data were qualitatively analysed using an NPT framework designed for intervention evaluation.

RESULTS

Clinical co-researchers readily incorporated the Family-Focused Support Conversation into their everyday work. The intervention changed family support from being solely patient-focused, providing information about patient needs, to family-focused, identifying family concerns about the significance and implications of discharge and facilitating family-focused care. Co-researchers reported an increase in family members' involvement in discharge decisions and end-of-life care planning.

CONCLUSION

The Family-Focused Support Conversation is a novel, evidenced-based and context specific intervention. Pilot implementation demonstrated the potential for the intervention to be used in acute hospitals to support family members during end-of-life care transitions. This subsequently informed a larger scale implementation study.

Sustainable solutions to mitigate occupational heat strain - an umbrella review of physiological effects and global health perspectives

BACKGROUND

Climate change is set to exacerbate occupational heat strain, the combined effect of environmental and internal heat stress on the body, threatening human health and wellbeing. Therefore, identifying effective, affordable, feasible and sustainable solutions to mitigate the negative effects on worker health and productivity, is an increasingly urgent need.

OBJECTIVES

To systematically identify and evaluate methods that mitigate occupational heat strain in order to provide scientific-based guidance for practitioners.

METHODS

An umbrella review was conducted in biomedical databases employing the following eligibility criteria: 1) ambient temperatures > 28 °C or hypohydrated participants, 2) healthy adults, 3) reported psychophysiological (thermal comfort, heart rate or core temperature) and/or performance (physical or cognitive) outcomes, 4) written in English, and 5) published before November 6, 2019. A second search for original research articles was performed to identify interventions of relevance but lacking systematic reviews. All identified interventions were independently evaluated by all co-authors on four point scales for effectiveness, cost, feasibility and environmental impact.

RESULTS

Following screening, 36 systematic reviews fulfilled the inclusion criteria. The most effective solutions at mitigating occupational heat strain were wearing specialized cooling garments, (physiological) heat acclimation, improving aerobic fitness, cold water immersion, and applying ventilation. Although air-conditioning and cooling garments in ideal settings provide best scores for effectiveness, the limited applicability in certain industrial settings, high economic cost and high environmental impact are drawbacks for these solutions. However, (physiological) acclimatization, planned breaks, shading and optimized clothing properties are attractive alternative solutions when economic and ecological sustainability aspects are included in the overall evaluation.

DISCUSSION

Choosing the most effective solution or combinations of methods to mitigate occupational heat strain will be scenario-specific. However, this paper provides a framework for integrating effectiveness, cost, feasibility (indoors and outdoor) and ecologic sustainability to provide occupational health and safety professionals with evidence-based guidelines.

Family group decision-making for children at risk of abuse or neglect: A systematic review

Background

Capturing the scale of child maltreatment is difficult, but few would argue that it is anything less than a global problem which can affect victims' health and well-being throughout their life. Systems of detection, investigation and intervention for maltreated children are the subject of continued review and debate.

Objectives

To assess the effectiveness of the formal use of family group decision-making (FGDM) in terms of child safety, permanence (of child's living situation), child and family well-being, and client satisfaction with the decision-making process.

Search Methods

Both published and unpublished manuscripts were considered eligible for this review. Library staff from Scholarly Information (Brownless Biomedical Library) University of Melbourne, conducted 14 systematic bibliographic searches. Reviewers also checked the reference lists of all relevant articles obtained, and reference lists from previously published reviews. Researchers also hand-searched 10 relevant journals.

Selection Criteria

Study samples of children and young people, aged 0-18 years, who have been the subject of a child maltreatment investigation, were eligible for this review. Studies had to have used random assignment to create treatment and control groups; or, parallel cohorts in which groups were assessed at the same point in time. Any form of FGDM, used in the course of a child maltreatment investigation or service, was considered an eligible intervention if it involved: a concerted effort to convene family, extended family, and community members; and professionals; and involved a planned meeting with the intention of working collaboratively to develop a plan for the safety well-being of children; with a focus on family-centred decision-making.

Data Collection and Analysis

Two review authors independently extracted the necessary data from each study report, using the software application Covidence. Covidence highlighted discrepancies between data extracted by separate reviewers, further analysis was conducted until a consensus was reached on what data were to be included in the review. Two authors also independently conducted analyses of study bias.

Main Results

Eighteen eligible study reports were found, providing findings from 15 studies, involving 18 study samples. Four were randomised controlled trials (RCTs; N = 941) the remainder employed quasi-experimental designs with parallel cohorts. Three of the quasi-experimental studies used prospective evaluations of nonrandomly assigned comparison groups (N = 4,368); the rest analysed pre-existing survey data, child protection case files or court data (N = 91,786). The total number of children studied was 97,095. The longest postintervention follow-up period was 3 years. Only four studies were conducted outside the United States; two in Canada and one in Sweden and one in the Netherlands. The review authors judged there to be a moderate or high risk of bias, in most of the bias categories considered. Only one study referenced a study protocol. Eleven of the fifteen studies were found to have a high likelihood of selection bias (73%). Baseline imbalance bias was deemed to be unlikely in just two studies, and highly likely in nine (60%). Confounding variables were judged to be highly likely in four studies (27%), and contamination bias was judged highly likely in five studies (33%). Researcher allegiance was rated as a high risk in three studies (20%) where the authors argued for the benefits of FGDM within the article, but without supporting references to an appropriate evidence base. Bias from differential diagnostic activity, and funding source bias, were less evident across the evidence reviewed. This review combines findings for eight FGDM outcome measures. Findings from RCTs were available for four outcomes, but none of these, combined in meta-analysis or otherwise, were statistically significant. Combining findings from the quasi-experimental studies provided one statistically significant finding, for the reunification of families, favouring FGDM. Ten effect sizes, from nine quasi-experimental studies, were synthesised to examine effects on the reunification of children with their family or the effect on maintaining in-home care; in short, the effect FGDM has on keeping families together. There was a high level of heterogeneity between the studies (I 2 = 92%). The overall effect, based on the combination of these studies was positive, small, but statistically significant: odds ratio (OR), 1.69 (confidence interval [CI], 1.03, 2.78). Holinshead's (2017) RCT also measured the maintenance on in-home care and reported a similar result: OR, 1.54 (CI, -0.19, 0.66) not statistically significant. The overall effect for continued maltreatment from meta-analysis of five quasi-experimental studies, favoured the FGDM group, but was not statistically significant: OR, 0.73 (CI, 0.48, 1.11). The overall combined effect for continued maltreatment, reported in RCTs, favoured the control group. But it was not statistically significant: OR, 1.29 (CI, 0.85, 1.98). Five effect sizes, from nonrandomised studies, were synthesised to examine the effect of FGDM on the number of kinship placements. The overall positive effect based on the combination of these studies was negligible: OR, 1.31 (CI, 0.94, 1.82). Meta-analysis was not possible with other outcomes. FGDM's role in expediting case processing and case closures was investigated in six studies, three of which reported findings favouring FGDM, and three which favoured the comparison group. Children's placement stability was reported in two studies: an RCT's findings favoured the control, while a quasi-experimental study's findings favoured FGDM. Three studies reported findings for service user satisfaction: one had only 30 participants, one reported a statistically significant positive effect for FGDM, the other found no difference between FGDM and a control. Engagement with support services was reported in two studies; neither reported statistically significant findings.

Authors' Conclusions

The current evidence base, in this field, is insufficient to draw conclusions about the effectiveness of FGDM. These models of child protection decision-making may help bring about better outcomes for children at risk, or they may increase the risk of further maltreatment. Further research of rigour, designed to avoid the potential biases of previous evaluations, is needed.

A Systematic Review and Meta-Analysis of the Effects of Food Safety and Hygiene Training on Food Handlers

Foodborne diseases are a significant cause of morbidity and mortality worldwide. Studies have shown that the knowledge, attitude, and practices of food handlers are important factors in preventing foodborne illness. The purpose of this research is to assess the effects of training interventions on knowledge, attitude, and practice on food safety and hygiene among food handlers at different stages of the food supply chain. To this end, we conducted a systematic review and meta-analysis with close adherence to the PRISMA guidelines. We searched for training interventions among food handlers in five databases. Randomized control trials (RCT), quasi-RCTs, controlled before-after, and nonrandomized designs, including pre-post studies, were analyzed to allow a more comprehensive assessment. The meta-analysis was conducted using the random-effects model to calculate the effect sizes (Hedges's g) and 95% confidence interval (CI). Out of 1094 studies, 31 were included. Results showed an effect size of 1.24 (CI = 0.89-1.58) for knowledge, an attitude effect size of 0.28 (CI = 0.07-0.48), and an overall practice effect size of 0.65 (CI = 0.24-1.06). In addition, subgroups of self-reported practices and observed practices presented effect sizes of 0.80 (CI = 0.13-1.48) and 0.45 (CI = 0.15-0.76) respectively.

Chinese Public's Engagement in Preventive and Intervening Health Behaviors During the Early Breakout of COVID-19: Cross-Sectional Study

BACKGROUND

Since January 2020, the coronavirus disease (COVID-19) swept over China and then the world, causing a global public health crisis. People's adoption of preventive and intervening behaviors is critical in curbing the spread of the virus.

OBJECTIVE

The aim of this study is to evaluate Chinese people's adoption of health behaviors in responding to COVID-19 and to identify key determinants for their engagement.

METHODS

An anonymous online questionnaire was distributed in early February 2020 among Mainland Chinese (18 years or older) to examine their engagement in preventive behaviors (eg, frequent handwashing, wearing masks, staying at home) and intervening behaviors (eg, advising family to wash hands frequently), and to explore potential determinants for their adoption of these health behaviors.

RESULTS

Out of 2949 participants, 55.3% (n=1629) reported frequent engagement in preventive health behaviors, and over 84% (n=2493) performed at least one intervening health behavior. Greater engagement in preventive behaviors was found among participants who received higher education, were married, reported fewer barriers and greater benefits of engagement, reported greater self-efficacy and emotional support, had greater patient-centered communication before, had a greater media literacy level, and had greater new media and traditional media use for COVID-19 news. Greater engagement in intervening behaviors was observed among participants who were married, had lower income, reported greater benefits of health behaviors, had greater patient-centered communication before, had a lower media literacy level, and had a greater new media and traditional media use for COVID-19 news.

CONCLUSIONS

Participants' engagement in coronavirus-related preventive and intervening behaviors was overall high, and the associations varied across demographic and psychosocial variables. Hence, customized health interventions that address the determinants for health behaviors are needed to improve people's adherence to coronavirus-related behavior guidelines.

Understanding further education as a context for public health intervention: qualitative findings from a study process evaluation

BACKGROUND

Over 1.2 million 16-18 year-olds are enrolled in further education (FE-advanced secondary education) in England. Life course transitions provide opportunities to change, establish or reinforce health behaviours. FE presents an opportunity for public health improvement, yet few interventions target this setting. Using a smoking prevention intervention, we explore how young people were viewed in FE and how this affected intervention acceptability.

METHODS

Eleven student and five staff focus groups were conducted in three intervention institutions (two colleges, one school sixth-form), as part of the process evaluation of a smoking prevention feasibility study. FE managers in intervention and control institutions were also interviewed (n = 5). Data were analysed using thematic analysis.

RESULTS

In both colleges and the sixth-form, students were viewed as emergent adults and treated differently from 'school-children', in practice if not in policy. Colleges permitted smoking in designated areas; in the school sixth-form smoking was unofficially tolerated but concealed from younger students. Using staff to deliver anti-smoking messages reintroduced an unwanted power dynamic which disrupted perceptions of students as young adults.

CONCLUSIONS

FE is an important setting for young people's health. Understanding the culture and context of FE is critical in designing acceptable and effective public health interventions.

Economic Evaluations of Public Health Interventions to Improve Mental Health and Prevent Suicidal Thoughts and Behaviours: A Systematic Literature Review

To review the literature on economic evaluations of public health interventions targeting prevention of mental health problems and suicide, to support evidence based societal resource allocation. A systematic review of economic evaluations within mental health and suicide prevention was conducted including studies published between January 2000 and November 2018. The studies were identified through Medline, PsychINFO, Web of Science, the National Health Service Economic Evaluation Database and Health Technology Assessment. The quality of relevant studies and the transferability of their results were assessed using a criterion set out by the Swedish Agency for Health Technology Assessment. Nineteen studies of moderate to high quality were included in this review, which evaluated 18 interventions in mental health and four interventions in suicide prevention. Fourteen (63%) of all interventions were cost-effective based on the conclusions from original papers. None of the studies that evaluated suicide prevention was of high quality. The interventions largely focused on psychological interventions at school, the workplace and within elderly care as well as screening and brief interventions in primary care. Nine studies (around 50% of included articles) had a high potential for transferability to the Swedish context. Public health interventions aiming to improve mental health have a high potential to be economically beneficial to society, but high-quality evidence on the cost-effectiveness of suicide prevention is limited.

Work-based strategies/interventions to ameliorate stressors and foster coping for clinical staff working in emergency departments: a scoping review of the literature

BACKGROUND

Exposure to occupational stressors is an issue for staff working in emergency departments, managers and health services. The aim of this review was to identify, map, and synthesise the range and scope of current evidence for work-based strategies or interventions used in emergency departments to reduce occupational stressors and/or improve staff coping.

METHODS

The framework proposed by Arksey and O'Malley guided this review. A search of CINAHL, MEDLINE, Scopus, Cochrane and PsycINFO databases from January 2007 to June 2019 was applied. A total of thirty-one articles were included in this review. Quality appraisal was undertaken.

RESULTS

Exposure to or impact of occupational stress and workplace violence were common foci. A range of outcomes (such as burnout levels, stress levels and quality of life) were measured in the included studies. All studies demonstrated some improvement in outcomes measured although most were evaluated for relatively short duration. Quality of evidence varied.

CONCLUSION

Strategies ranging from mindfulness to organisational redesign have been trialed to diminish stress and enhance coping of emergency department staff. Understanding the effectiveness of strategies is an important early step in improving the working environment for emergency department clinicians in an evidence-informed manner. Such information may be of use to managers to inform decision making regarding the most appropriate strategy to implement in their emergency department.

Tailoring Process and Impact Evaluation of a "Cash-Plus" Program: The Value of Using a Participatory Program Impact Pathway Analysis

BACKGROUND

Evaluations are often limited to affirming what impact health and nutrition interventions have, without providing enough insights into "how/why" impacts are achieved.

OBJECTIVES

This article describes how a Program Impact Pathway (PIP) analysis was used to tailor theory-driven impact and process evaluation of a "Cash-Plus" program combining unconditional cash transfers with behavior change communication (BCC) activities, which was implemented to improve children's growth in Togo.

METHODS

A theoretical PIP diagram was developed using existing literature, program documentation, and interviews with the program's stakeholders at the central level. Next, the PIP diagram was refined through 2 regional participatory workshops, 6 mo after the program began. Workshop participants were multilevel field implementers and were asked to 1) discuss their vision of the program's objectives; 2) describe the "inputs-process-outputs-outcomes-impacts" flow; 3) reflect on modifiers that may arise along the PIP; and 4) report bottlenecks in the program's conception or implementation and suggest corrective actions. The PIP was used to determine research questions that should be investigated during impact or process evaluation and guided the choice of data collection methods and tools.

RESULTS

The PIP analysis identified 3 impact pathways, all based on the synergy between cash and raised women's knowledge. Along these pathways, the motivation and workload of frontline workers, along with issues in cash flow, were identified as factors that may affect the delivery of activities, whereas women's control over resources, time availability, support from relatives, and the presence of markets and health and school services were recognized as factors that may influence the uptake of activities. Improved communication between stakeholders and increased involvement of husbands were suggested for better impact achievement.

CONCLUSIONS

The participatory PIP analysis helped implementers and evaluators to share a common vision of the program's objective and logic, encouraged communication across sectors, and facilitated course-adjustments of the program.
