Abstract For complex public health interventions to be effective their implementation needs to adapt to the situation of those implementing and those receiving the intervention. While context matter for intervention implementation and effect, we still insist on learning from cross-country comparison of implementation. Next methodological challenges include how to increase learning from implementation of complex public health interventions from various context. The interventions presented in this workshop all aims to improve quality of reproductive health care for immigrants, however with different focus: contraceptive care in Sweden, group based antenatal care in France, and management of pregnancy complications in Denmark. What does these interventions have in common and are there cross cutting themes that help us to identify the larger challenges of reproductive health care for immigrant women in Europe? Issues shared across the interventions relate to improved interactional dynamics between women and the health care system, and theory around a woman-centered approach and cultural competence of health care providers and systems might enlighten shared learnings across the different interventions and context. Could the mechanisms of change be understood using theoretical underpinnings that allow us to better generalize the finding across context? What adaption would for example be needed, if the Swedish contraceptive intervention should work in a different European setting? Should we distinguish between adaption of function and form, where the latter might be less important for intervention fidelity? These issues will shortly be introduced during this presentation using insights from the three intervention presentations and thereafter we will open up for discussion with the audience.

Abstract Patient information material (PIM) is omnipresent in healthcare. It is used to convey information or to familiarize potential end-users to offers of support. PIM recaps or elaborates on relevant information and offers recommendation for action. However, the quality of available PIM varies. When the formal and content-related quality of PIM is suboptimal, it not only fails to be effective but can also lead to uncertainty, misunderstandings, resistance or ignorance (e.g. of a support offer). Highly complex information requires much attention on the quality of the PIM, especially with respect to end-users (e.g. vulnerable groups). Excellent communication through the use of PIM is thus essential within complex interventions. Checklists, such as 'Discern' or 'PEMAT', as well as criteria catalogues or evidence-based patient information standards, may assist in the development, quality assessment and optimization of PIM. The inclusion of the end-users is recommended but for various reasons does not often take place. The innovative “integrated, cross-sectional Psycho-Oncology” (isPO) programme, offers needs-driven, professional support to all adult, newly diagnosed cancer patients early in their sickness trajectory. IsPO was developed in 2018. It was implemented and a formative evaluated in 2019. When developing this programme, different PIM were created top-down by the programme designers. During implementation, it became evident that these PIM materials required further improvement. A testing and optimization process started using the participatory health research (PHR) approach and was completed in a five-month period. A PIM-optimisation team was founded, which included the project partners involved in the network support, self-help organisations and the external evaluation institute. A practical instrument (PIM-checklist) for optimising the isPO-PIM was designed, piloted and used for testing by end-users, isPO service providers, and experts. Based on the recommendations in the checklist, the material was revised accordingly. Additionally, the PIM was completed with the design of two new components. Four optimisation rounds were conducted. The optimized PIM was tested on its comprehensibility (for end-users) and its usability (for service providers). During the presentations, the audience is invited to comment on critical questions that may appear during optimization (e.g. timing). Afterwards, there will be a skill building part with a focus on collaborative learning (45 minutes). First, we will focus on the requirements for a practical instrument that is handy for end-users, service providers and experts (mind mapping exercise). Finally, participants will be able to explore the following topics “World Café” discussion: (1) how to plan, conduct and communicate the development of optimization of PIM in a CI program, (2) what needs to be considered for the optimization (e.g. team composition, resources), and (3) how to continuously achieve end-userś participation. Key messages Excellent PIM are essential for a complex interventiońs success in practice and must include information and foster actionability. the iterative PIM design processes benefits from high user participation.

AbstractThere is growing interest in social network-based programmes to improve health, but rigorous methods using Social Network research to evaluate the process of these interventions is less well developed. Using data from the “STis And Sexual Health” (STASH) feasibility trial of a school-based, peer-led intervention on sexual health prevention, we illustrate how network data analysis results can address key components of process evaluations for complex interventions—implementation, mechanisms of impacts, and context. STASH trained students as Peer Supporters (PS) to diffuse sexual health messages though face-to-face interactions and online Facebook (FB) groups. We applied a Multilevel Exponential Random Graph modelling approach to analyse the interdependence between offline friendship relationships and online FB ties and how these different relationships align. Our results suggest that the creation of online FB communities mirrored offline adolescent groups, demonstrating fidelity of intervention delivery. Data on informal friendship networks related to student’s individual characteristics (i.e., demographics, sexual health knowledge and adherence to norms, which were included for STASH), contributed to an understanding of the social relational ‘building’ mechanisms that sustain tie-formation. This knowledge could assist the selection of opinion leaders, improving identification of influential peers situated in optimal network positions. This work provides a novel contribution to understanding how to integrate network research with the process evaluation of a network intervention.

Abstract Background Obesity is a chronic disease that contributes to additional comorbidities including diabetes, kidney disease and several cancers. Change4Campbelltown implemented a ‘whole of system’ approach to address childhood overweight and obesity. We present methods to track implementation and stakeholder engagement in Change4Campbelltown. Methods Change4Campbelltown aimed to build capacity among key leaders and the broader community to apply techniques from systems thinking to develop community-led actions that address childhood obesity. Change4Campbelltown comprised development of a stakeholder-informed Causal Loop Diagram (CLD) and locally-tailored action plan, formation of key stakeholder and community working groups to prioritise and implement actions, and continuous monitoring of intervention actions. Implementation data included an action register, stakeholder engagement database and key engagement activities and were collected quarterly by the project management team over 2 years of reporting. Results Engagement activities increased level of community engagement amongst key leaders, the school-sector and community members. Community-led action increased as engagement increased and this action is mapped directly to the primary point of influence on the CLD. As action spread diversified across the CLD, the geographical spread of action within the community increased. Conclusions This paper provides a pragmatic example of the methods used to track implementation of complex interventions that are addressing childhood overweight and obesity.

Abstract Background Qualitative Comparative Analysis (QCA) is a method for identifying the configurations of conditions that lead to specific outcomes. Given its potential for providing evidence of causality in complex systems, QCA is increasingly used in evaluative research to examine the uptake or impacts of public health interventions. We map this emerging field, assessing the strengths and weaknesses of QCA approaches identified in published studies, and identify implications for future research and reporting. Methods PubMed, Scopus and Web of Science were systematically searched for peer-reviewed studies published in English up to December 2019 that had used QCA methods to identify the conditions associated with the uptake and/or effectiveness of interventions for public health. Data relating to the interventions studied (settings/level of intervention/populations), methods (type of QCA, case level, source of data, other methods used) and reported strengths and weaknesses of QCA were extracted and synthesised narratively. Results The search identified 1384 papers, of which 27 (describing 26 studies) met the inclusion criteria. Interventions evaluated ranged across: nutrition/obesity (n = 8); physical activity (n = 4); health inequalities (n = 3); mental health (n = 2); community engagement (n = 3); chronic condition management (n = 3); vaccine adoption or implementation (n = 2); programme implementation (n = 3); breastfeeding (n = 2), and general population health (n = 1). The majority of studies (n = 24) were of interventions solely or predominantly in high income countries. Key strengths reported were that QCA provides a method for addressing causal complexity; and that it provides a systematic approach for understanding the mechanisms at work in implementation across contexts. Weaknesses reported related to data availability limitations, especially on ineffective interventions. The majority of papers demonstrated good knowledge of cases, and justification of case selection, but other criteria of methodological quality were less comprehensively met. Conclusion QCA is a promising approach for addressing the role of context in complex interventions, and for identifying causal configurations of conditions that predict implementation and/or outcomes when there is sufficiently detailed understanding of a series of comparable cases. As the use of QCA in evaluative health research increases, there may be a need to develop advice for public health researchers and journals on minimum criteria for quality and reporting.

<b><i>Background:</i></b> Mesh-related complications resulting from pelvic organ prolapse (POP) reconstruction operations may be a devastating experience leading to multiple and complex interventions. <b><i>Objectives:</i></b> The aim of the study was to describe the experience and time frame of management of mesh-related complications in women treated for POP or stress urinary incontinence in a tertiary center. <b><i>Methods:</i></b> 1,530 cases of mesh-related complications were accessed regarding their clinical presentation, number of surgeries, and timeline of surgical treatments to treat multiple clinical complaints until the ultimate operation where all the meshes were removed in a single tertiary center. <b><i>Results:</i></b> The studied population revealed to be a highly referred one with only 10.2% of the cases implanted at our center. Clinical presentation varied widely with 48.7% referring pain as the chief complaint, while 31.3% complained of voiding dysfunctions, 2.5% reported genital prolapses, 2.2% complained of vaginal problems, and 1.2% noted intestinal problems as the main clinical complaint. Only 4.8% of the cases presented mesh erosion at examination; 57.8% of the cases required more than 1 operation to address the mesh-related problems. Sixty-eight cases had more than 10 operations up to complete removal. Three clusters of patients could be identified: (i)–those from whom the mesh was promptly removed after clinical problems emerged, (ii) those with slowly evolving problems, and (iii) those with escalating problems despite treatment attempts. <b><i>Conclusions:</i></b> Mesh-related complications after pelvic floor reconstruction are an evolving disease with diverse clinical presentation. The identified time-related problems and the multiple failed attempts to treat their complications warrant attention with continuous monitoring of these patients and aggressive removal of the mesh if the clinical complaint cannot be swiftly managed.
