Understanding the complexity of population health interventions: assessing intervention system theory (ISyT)

Exploring and describing alcohol harm reduction interventions: a scoping review of literature from the past decade in the western world

CONTEXT

Regular alcohol use is a predominant risk factor for disease, injury, and social harm. While robust evidence is advocating for implementing interventions to reduce the harms of illegal substance use, less literature is dedicated to identifying and understanding interventions aiming at reducing the various harms associated with alcohol.

OBJECTIVES

This review describes how alcohol harm reduction (AHR) interventions are currently conducted and analyzes the facilitators and barriers identified by the studies on their efficacy.

METHOD

This scoping review with evidence appraisal included articles published between 2011 and 2022, addressing one or more AHR interventions for population of at least 18 years (including alcohol user who have an addiction but also alcohol user with harmful drinking), conducted in North industrialized countries (Europe, Nort America, Australia).

RESULTS

Among the 61 articles selected, we identified several forms of support (face-to-face or remote, support in residential settings, structural interventions, and interventions created upon spontaneous initiatives), and strategies of intervention were also analyzed (the ones based upon learning and skill development, the ones based upon psychological support, the ones focusing upon socio-economic conditions, strategies focusing on the coordination and adaptation of the care system, and those strategies based on peer support). The facilitators linked to fundamental characteristics of the interventions were the promotion of empowerment and autonomy of beneficiaries, setting objectives tailored to individual needs, professionals harmonizing their values, evidence-based interventions taking into account cultural contexts, and comprehensive and holistic support. Practical facilitators from the intervention process consist of increasing the number of sessions, involvement, and formation of members of staff, disposing of the necessary resources, and using technological tools.

DISCUSSION

The sheer variety of AHR interventions demonstrates that this is a fertile field in terms of intervention design and innovation. This work illustrates the importance of designing effective, adapted harm reduction interventions, prioritizing interventions that make support more accessible to more people. This also prompts us to consider the potential benefits of invoking proportionate universalism in the design of AHR interventions in order to operationalize alcohol harm reduction philosophy. accessible to more people.

Addressing current challenges in population health intervention research for health promotion

This article explores the role of population health intervention research (PHIR) in enhancing health promotion in France, stressing the importance of a more in-depth understanding and thorough analysis of healthcare interventions. Established in 2022, the So-RISP network aims to structure the PHIR field, consolidating expertise from renowned teams specializing in PHIR, primary cancer prevention, and addiction. In January 2023, So-RISP members convened a national workshop. The workshop aimed to share the specificities of PHIR and particularly to clarify the use of theories in PHIR. A qualitative analysis of this workshop was conducted to aid in building a shared and well-defined knowledge base for PHIR stakeholders. Results highlight the necessity of developing a unified terminology and increasing reflexivity among PHIR stakeholders for enhanced effectiveness. The article also identifies key challenges, including the need for interdisciplinary collaboration, facilitating social transformation, and integrating various contexts in intervention analysis.

Young people returning to alcohol and other drug services as incremental treatment

Young people who attend intensive alcohol and other drug (AoD) treatment commonly do so more than once. This paper aims to understand precipitators, enablers and barriers to young people's re-engagement in programs. Data come from a longitudinal qualitative study involving three waves of interviews with Australian young people recruited while attending intensive AoD programs (n = 38 at wave 1). We found that young people's ambitions for what they might achieve with a new stay and capacity to benefit from programs, evolved. Skills learnt in earlier stays or changed life circumstances often helped them achieve better outcomes subsequently. Ongoing contact with an AoD worker was the most important enabler to service re-engagement. Across the span of a year, we saw most young people in our study sample develop a stronger sense of wellbeing and control over substance use. While researchers tend to focus on evaluating outcomes associated with single stays at specific programs, young people think about their trajectories towards managing substance use and their lives as occurring more holistically, supported by engagements with a range of services. We argue that the notion of incremental treatment is useful in depicting the synergistic effects of service engagement over time.

A review of implementation and evaluation frameworks for public health interventions to inform co-creation: a Health CASCADE study

BACKGROUND

By including the needs and perspectives of relevant stakeholders, co-creation is seen as a promising approach for tackling complex public health problems. However, recommendations and guidance on how to plan and implement co-creation are lacking. By identifying and analysing existing implementation and evaluation frameworks for public health, this study aims to offer key recommendations for professional stakeholders and researchers wanting to adopt a co-creation approach to public health interventions.

METHODS

Firstly, PubMed and CINAHL databases were screened for articles introducing original implementation and evaluation frameworks for public health interventions. Backwards snowballing techniques were applied to the included papers. Secondly, identified frameworks were classified and relevant data extracted, including steps and constructs present in the frameworks. Lastly, recommendations were derived by conducting thematic analysis on the included frameworks.

RESULTS

Thirty frameworks were identified and data related to their nature and scope extracted. The frameworks' prominent steps and constructs were also retrieved. Recommendations related to implementation and evaluation in the context of co-creation were included.

CONCLUSION

When engaging in co-creation, we recommend including implementation considerations from an early stage and suggest adopting a systems thinking as a way to explore multiple levels of influence, contextual settings and systems from an early planning stage. We highlight the importance of partnering with stakeholders and suggest applying an evaluation design that is iterative and cyclical, which pays particular attention to the experience of the engaged co-creators.

Conditions for adherence to videoconference-based programs promoting adapted physical activity in cancer patients: a realist evaluation

BACKGROUND

Although moderate physical activity (PA) during cancer treatment has been associated with improved quality of life, reduced side effects, and even lower mortality, many barriers to successful implementation remain. Digital technology has been perceived as an effective lever for overcoming access and motivational issues but few studies have been performed to confirm this assumption. The "VISIO-AJUST" study explored the factors affecting the conditions of adherence to video-conference-based PA programs in patients undergoing cancer treatment.

METHODS

The VISIO-AJUST study was based on a qualitative successive case approach, guided by the principles of the realist evaluation, and applied to two French programs of PA, following three main steps: (1) Identification of factors likely to influence conditions of patients' adherence; (2) Elaboration and testing of explanatory "Context-Mechanism-Outcome (CMO)" configurations; (3) Refinement of CMO configurations, in order to understand what, how, for whom, and under what circumstances video-conference-based PA programs work.

RESULTS

Five main CMO configurations were found to be associated with adherence to video-conferencing-based PA programs, promoting (i) accessibility and a supportive environment for adapted physical activity, (ii) a setting conducive to sociability despite distance, (iii) Confidence and security of practice, (iv) a combination of several motivational levers in favor of continuity of effort and progress, (v) regularity of the sessions, progressiveness in the effort and evaluation of progress as a basis for the adoption of a regular physical practice.

CONCLUSION

This study provides original insights into the use of videoconferencing to enable patients to improve their PA during cancer treatment. Future research with long-term follow-up would allow for a better understanding of the key conditions promoting sustainable behavior change.

Patterns in bottlenecks for implementation of health promotion interventions: a cross-sectional observational study on intervention-context interactions in the Netherlands

BACKGROUND

From a complex systems perspective, implementation should be understood as the introduction of an intervention in a context with which it needs to interact in order to achieve its function in terms of improved health. The presence of intervention-context interactions could mean that during implementation particular patterns of crucial interaction points might arise. We examined the presence of - and regularities in - such 'bottlenecks for implementation', as this could create opportunities to predict and intervene in potential implementation problems.

METHODS

We conducted a cross-sectional observational study against the background of municipal intersectoral policymaking in the Netherlands. We asked implementers of health promotion interventions to identify bottlenecks by rating the presence and importance of conditions for implementation in a range of intervention systems. We used descriptive statistics to characterize these systems (by their behaviour change method, health theme and implementation setting) and the conditions that acted as bottlenecks. After stratifying bottlenecks by intervention system and the system's characteristics, we tested our hypotheses by comparing the number and nature of the bottlenecks that emerged.

RESULTS

More than half of the possible conditions were identified as a bottleneck for implementation. Bottlenecks occurred in all categories of conditions, e.g., relating to the implementer, the intervention, and political and administrative support, and often connected with intersectoral policymaking, e.g., relating to the co-implementer and the co-implementer's organization. Both our hypotheses were supported: (1) Each intervention system came across a unique set of - a limited number of - conditions hampering implementation; (2) Most bottlenecks were associated with the characteristics of the system in which they occurred, but bottlenecks also appeared in the absence of such an association, or remained absent in the presence thereof.

CONCLUSIONS

We conclude that intervention-context interactions in integrated health policymaking may lead to both regularities and variations in bottlenecks for implementation. Regularities may partly be predicted by the function of an intervention system, and may serve as the basis for building the capacity needed for the structural changes that can bring about long-lasting health improvements. Variations may point at the need for flexibility in further tailoring the implementation approach to the - mostly unpredictable - problems at individual sites.

Realist evaluation of three programmes aimed at reducing harm and risks associated with alcohol consumption in the Nouvelle Aquitaine region of France: the ECIAE study protocol

INTRODUCTION

In Europe, alcohol consumption is responsible for many diseases, disabilities, injuries and premature deaths. In France, alcohol consumption represents an important health burden, due to its frequency, scale and the serious damage it causes. One of the keys to addressing the problem would appear to be the adoption of harm and risk reduction approaches. In order to operationalise this strategy, the Nouvelle Aquitaine Regional Health Agency is funding three different programmes to reduce the harm and risks associated with alcohol consumption: Alcochoix, Iaca and ETP (Education Thérapeutique du Patient) Conso-repère. We are interested in understanding how, under what circumstances, through which mechanisms and for which population the different programmes work.

METHODS AND ANALYSIS

The ECIAE study (a cross-evaluation of the 3 programs Iaca/Alcochoix/ ETP (Patient Therapeutic Education) is a theory-based evaluation where the realist evaluation method is used to explore effects, intervention mechanisms and the influence of context on outcomes. This realist evaluation is based on multiple case studies in two nested levels. At the first level, each centre implementing the programme will represent a case. At the second level, each programme will represent a case in which a set of activities is conducted to achieve risk reduction objectives.

ETHICS AND DISSEMINATION

The project will be carried out in full compliance with existing legislation and international conventions. It was subject to analysis, including a privacy impact assessment conducted by the Data Protection Officer of the University of Bordeaux. The University of Bordeaux has ensured that all the regulatory procedures related to the ECIAE study have been carried out. The dissemination plan includes scientific papers, seminars, a report and recommendation and a public restitution. The study will provide evidence-based results to help health authorities roll out strategies to reduce risks and harm associated with alcohol use.

Realist evaluation of health promotion interventions: a scoping review

This scoping review aims to give a narrative account of existing realist evaluation practices in health promotion. Realist evaluations of health promotion interventions published between 2010 and 2021 were identified by searching five academic databases: Embase, Pubmed, PsycINFO, ScienceDirect and Scopus. A data-charting form was created based on the characteristics of realist evaluation and four core features of an approach appropriate for evaluating health promotion interventions. Seventeen articles met the inclusion criteria. These were classified into two types of studies: those aiming to build an initial program theory and those aiming to test an initial program theory. Our results revealed a great variety of realist evaluation practices and uncovered a growing interest in realist evaluation over the years. Our searches identified a lack of participative practice and capacity-building intention. Our examination of the data collection and analysis methods points to some common practices in using multi-methods. Perspectives on realist evaluation practices and on assessing the effectiveness of health promotion have been identified.

Conditions for the success and the feasibility of health mediation for healthcare use by underserved populations: a scoping review

OBJECTIVE

This article aims to analyse the conditions under which health mediation for healthcare use is successful and feasible for underserved populations.

METHOD

We conducted a scoping review on the conditions for effective health mediation according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews standards. We searched for articles in the following databases: PubMed, PsychINFO, Scopus and Cairn published between 1 January 2015 and 18 December 2020. We selected the articles concerning health mediation interventions or similar, implemented in high-income countries and conducted among underserved populations, along with articles that questioned their effectiveness conditions. We created a two-dimensional analysis grid of the data collected: a descriptive dimension of the intervention and an analytical dimension of the conditions for the success and feasability of health mediation.

RESULTS

22 articles were selected and analysed. The scoping review underlines many health mediation characteristics that articulate education and healthcare system navigation actions, along with mobilisation, engagement, and collaboration of local actors among themselves and with the populations. The conditions for the success and the feasability were grouped in a conceptual framework of health mediation.

CONCLUSION

The scoping review allows us to establish an initial framework for analysing the conditions for the success and the feasability of health mediation and to question the consistency of the health mediation approach regarding cross-cutting tensions and occasionally divergent logic.

[Evaluating population health interventions : The contributions of theory-driven evaluations]

Population health intervention research has been characterized by the deployment of scientific methods designed to produce knowledge on policy and program interventions directly or indirectly involving the health sector, and potentially affecting population health. The proposed solutions encompass a multitude of interventions of variable types, scale, focus and implementation, rendering them particularly complex and difficult to understand. This complexity raises major conceptual and methodological issues because in reality, we assess not an intervention, but rather a set of interventional elements interacting with those specific to the context in which they appear. It is the interactions that produce effects, to the extent that it makes little sense to speak of an intervention, and more sense to consider an interventional system defined by the interactions. To grasp the numerous elements brought into play, it behooves us to amalgamate evaluation paradigms and approaches. In a precise context, theory-driven evaluations are of pronounced interest. This article presents the main principles of this type of evaluation by focusing on its capacity to shed light on the stakes involved in intervention/context interplay, and by putting forward conclusions transferable to population health research.

Analyzing implementation of public health interventions : a need for rigor, and the challenges of stakeholder involvement

OBJECTIVES

This article shows how conceptual models can help to develop and evaluate public health interventions. It also reports on the challenges of getting stakeholders involved.

METHOD

The analysis is based on the reflexive approach applied by the authors during their participation in two public health intervention research (PHIR) projects, in France and in Burkina Faso.

RESULTS

In Paris, PHIR aimed to enable sub-Saharan immigrants to appropriate the existing means of prevention and sexual health care and to strengthen their empowerment in view of preserving their health. Evaluation was carried out using mixed methods. The intervention process theory is based on Ninacs' conceptual model of individual empowerment. The Consolidated Framework For Implementation Research (CFIR) was mobilized a posteriori to analyze the process. PHIR stemmed from collaboration between a research team and two associations. The different stakeholders were involved in the evaluation process, as were, at certain times, persons in highly precarious situations. In Ouagadougou, a community-based dengue vector control intervention was deployed to address an essential but neglected need. As regards evaluation, we opted for a holistic, mixed method approach (effectiveness and process). The contents of the intervention were determined based on tacit knowledge, a community preference survey and solid evidence. The theoretical framework of the intervention consisted in an eco-biological model of vector control. The implementation analysis combined an internal assessment of implementation fidelity with an external CFIR process analysis. All stakeholders were involved in the evaluation process.

DISCUSSION

Analysis confirmed not only the value of process evaluations in PHIR, but also the primordial importance of a rigorous approach. Stakeholder involvement is a major challenge to be addressed early in the planning of RISPs; with this in mind, effective and ethically sound assessment mechanisms need to be drawn up. Interdisciplinary evaluative approaches should be preferred, and the use of justified, relevant, and flexible frameworks is highly recommended.

CONCLUSION

Lessons learned for those wishing to engage in the process evaluation of a public health intervention are hereby presented.

Evaluation proposal of a national community-based obesity prevention programme: a novel approach considering the complexity perspective

Community-based obesity prevention programmes are considered an important strategy to curb the obesity epidemic. The JOGG (Youth At a Healthy Weight) approach is a large-scale community-based programme for childhood obesity prevention in the Netherlands that has been implemented over the past ten years. Practice-based development of the programme, both at the national and local level, increasingly poses challenges for its evaluation. One considerable challenge is the increasing acknowledgement of the complexity in the JOGG-approach, characterized by (a) objectives that vary locally, (b) adaptions to the programme over time in response to a community's shifting needs, challenges and opportunities, and (c) emergent outcomes and non-linear causality.We propose an evaluation framework that highlights elements of the complex local practice, including the local programme theory, implementation, adaption, the influence of context and feedback loops and intended as well as emergent and unintended outcomes. By studying each of these elements in practice, we hope to learn about principles that guide effective obesity prevention across contexts. The results of the proposed evaluation will inform both practice and research.Considering complexity in evaluation is a relatively new challenge in public health and therefore an emergent research area. The proposed framework for complex evaluations allows to retrospectively evaluate a programme that was implemented and developed in practice, and enables us to learn from practice-based experiences. Following the ISBNPA Dare2Share initiative, we kindly invite other researchers in the field to share their ideas and experiences regarding integration of complexity in evaluation.

'Writing budgets for meetings and teas?': a multitheoretical analysis of intragovernmental coordination for multisectoral action for health in Uganda

Introduction

Coordination across policy domains and among government agencies is considered critical for addressing complex challenges such as inequities, urbanisation and climate change. However, the factors influencing coordination among government entities in low-income and middle-income countries are not well known. Although theory building is well suited to explain complex social phenomena, theory-based health policy and systems studies are limited. This paper examined the factors influencing coordination among government entities at the central government level in Uganda.

Methods

This theory-based case study used a qualitative approach. Primary data were collected through 26 national-level key informant interviews supplemented with a review of 6 national strategic and policy documents. Data were analysed abductively using a multitheoretical framework combining the transaction cost economics theory, principal–agent theory, resource dependence theory and political economy perspective.

Results

Complex and dynamic interactions among different factors, both internal and external to the government, were found. Interdependencies, coordination costs, non-aligned interests, and institutional and ideational aspects were crucial factors. The power dynamics within the bureaucratic structures and the agency of the coordinated entities influence the effectiveness of coordination efforts. New public management principles promoted in the 1990s by donor institutional strengthening projects (characterised by agencification and setting up of independent agencies to circumvent ineffective big line ministries) created further fragmentation within the government. The donors and international agendas were occasionally supportive but sometimes counterintuitive to national coordination efforts.

Conclusion

The multitheoretical framework derives a deep analysis of the factors that influence organisational decision-making to coordinate with others or not. Achieving intragovernmental coordination requires more time and resources to guide the software aspects of institutional change—articulating a shared vision on coordination across government. Shaping incentives to align interests, managing coordination costs and navigating historical-institutional contexts are critical. Countervailing political actions and power dynamics should be judiciously navigated.
