Using the multiple streams model to elicit an initial programme theory: from policy dialogues to a roadmap for scaling up integrated care.

INTRODUCTION: The 'SCale-Up diaBetes and hYpertension care' Project aims to support the scale-up of integrated care for diabetes and hypertension in Cambodia, Slovenia and Belgium through the co-creation, implementation and evaluation of contextualised roadmaps. These roadmaps offer avenues for action and are built on evidence as well as stakeholder engagement in policy dialogues. Roadmaps and policy dialogues are very much intertwined and considered to be key elements for successful stakeholder-supported scale-up in integrated chronic care. Yet, little is known about how, why and under which conditions policy dialogue leads to successful roadmap implementation and scale-up of integrated care. Therefore, this study aims to use a realist approach to elicit an initial programme theory (IPT), using political science theories on the policy process. METHODS: To develop the IPT, information from different sources was collected. First, an exploratory literature review on policy dialogue and scale-up definitions and success factors was performed, identifying theoretical frameworks, empirical (case) studies and realist studies (information gleaning). Second, research workshops on applying theory to the roadmap for scale-up (theory gleaning) were conducted with a multidisciplinary expert team. We used the intervention-context-actors-mechanism-outcome configuration to synthesise information from the sources into a configurational map. RESULTS: The information and theory gleaning resulted into an IPT, hypothesising how policy dialogues can contribute to roadmap success in different policy stages. The IPT draws on political science theory of the multiple streams model adapted by Howlett et al to include five streams (problem, solution, politics, process and programme) that can emerge, converge and diverge across all five policy stages. CONCLUSION: This paper aims to extend the knowledge base on the use of policy dialogues to build a roadmap for scale-up. The IPT describes how (dynamics) and why (theories) co-created roadmaps are expected to work in different policy stages.

Management of Benign Phyllodes Tumors: A Dutch Population-Based Retrospective Cohort Between 1989 and 2022.

BACKGROUND: Phyllodes tumors (PTs) are rare tumors of the breast. The current National Comprehensive Cancer Network (NCCN) guidelines recommend excision of benign PTs, accepting close or positive margins. Controversy about the optimal treatment for benign PTs remains, especially regarding the preferred margin width after surgical excision and the need for follow-up evaluation. METHODS: A nationwide retrospective study analyzed the Dutch population from 1989 to 2022. All patients with a diagnosis of benign PT were identified through a search in the Dutch nationwide pathology databank (Palga). Information on age, year of diagnosis, size of the primary tumor, surgical treatment, surgical margin status, and local recurrence was collected. RESULTS: The study enrolled 1908 patients with benign PT. The median age at diagnosis was 43 years (interquartile range [IQR], 34-52 years), and the median tumor size was 30 mm (IQR, 19-40 mm). Most of the patients (95%) were treated with breast-conserving surgery (BCS). The overall local recurrence rate was 6.2%, and the median time to local recurrence was 31 months (IQR, 15-61 months). Local recurrence was associated with bilaterality of the tumor (odds ratio [OR], 4.91; 95% confidence interval [CI], 2.95-28.30) and positive margin status (OR, 2.51; 95% CI 1.36-4.63). The local recurrence rate was 8.9% for the patients with positive excision margins and 4.0% for the patients with negative excision margins. Notably, for 27 patients (22.6%) who experienced a local recurrence, histologic upgrading of the recurrent tumor was reported, 7 (5.9%) of whom had recurrence as malignant lesions. CONCLUSIONS: This nationwide series of 1908 patients showed a low local recurrence rate of 6.2% for benign PT, with higher recurrence rates following positive margins.

From Implementation Towards Change Management: A Plea for a Multi-stakeholder View on Innovation Implementation Comment on "What Managers Find Important for Implementation of Innovations in the Healthcare Sector - Practice Through Six Management Perspectives".

In their 2021 paper, Palm and Persson Fischier focus on the enabling factors that can facilitate innovation implementation, specifically the step of moving from idea generation to implementation in a healthcare context. The authors address the lack of concretisation of theoretical perspectives related to the implementation of innovations and hence propose to work holistically with six management perspectives. Our commentary provides new interdisciplinary angles to the six perspectives, from management and organisation literature to theory of change management. This provides future innovation managers with different viewpoints and inspires creative thinking and reflection. Our commentary also critiques the emphasis on the enablers and hence a constructionist-based approach to change management. We plea that a focus on the 'good, bad, and ugly'-or rather all moods of change-is warranted in order to support holistic and successful change.

Applying systems thinking to identify enablers and challenges to scale-up interventions for hypertension and diabetes in low-income and middle-income countries: protocol for a longitudinal mixed-methods study.

INTRODUCTION: There is an urgent need to reduce the burden of non-communicable diseases (NCDs), particularly in low-and middle-income countries, where the greatest burden lies. Yet, there is little research concerning the specific issues involved in scaling up NCD interventions targeting low-resource settings. We propose to examine this gap in up to 27 collaborative projects, which were funded by the Global Alliance for Chronic Diseases (GACD) 2019 Scale Up Call, reflecting a total funding investment of approximately US$50 million. These projects represent diverse countries, contexts and adopt varied approaches and study designs to scale-up complex, evidence-based interventions to improve hypertension and diabetes outcomes. A systematic inquiry of these projects will provide necessary scientific insights into the enablers and challenges in the scale up of complex NCD interventions. METHODS AND ANALYSIS: We will apply systems thinking (a holistic approach to analyse the inter-relationship between constituent parts of scaleup interventions and the context in which the interventions are implemented) and adopt a longitudinal mixed-methods study design to explore the planning and early implementation phases of scale up projects. Data will be gathered at three time periods, namely, at planning (TP), initiation of implementation (T0) and 1-year postinitiation (T1). We will extract project-related data from secondary documents at TP and conduct multistakeholder qualitative interviews to gather data at T0 and T1. We will undertake descriptive statistical analysis of TP data and analyse T0 and T1 data using inductive thematic coding. The data extraction tool and interview guides were developed based on a literature review of scale-up frameworks. ETHICS AND DISSEMINATION: The current protocol was approved by the Monash University Human Research Ethics Committee (HREC number 23482). Informed consent will be obtained from all participants. The study findings will be disseminated through peer-reviewed publications and more broadly through the GACD network.

Scaling-up an Integrated Care for Patients with Non-communicable Diseases: An Analysis of Healthcare Barriers and Facilitators in Slovenia and Belgium.

INTRODUCTION: Although the concept of integrated care for non-communicable diseases was introduced at the primary level to move from disease-centered to patient-centered care, it has only been partially implemented in European countries. The aim of this study was to identify and compare identified facilitators and barriers to scale-up this concept between Slovenia and Belgium. METHODS: This was a qualitative study. Fifteen focus groups and fifty-one semi-structured interviews were conducted with stakeholders at the micro, meso and macro levels. In addition, data from two previously published studies were used for the analysis. Data collection and analysis was initially conducted at country level. Finally, the data was evaluated by a cross-country team to assess similarities and differences between countries. RESULTS: Four topics were identified in the study: patient-centered care, teamwork, coordination of care and task delegation. Despite the different contexts, true teamwork and patient-centered care are limited in both countries by hierarchies and a very heavily skewed medical approach. The organization of primary healthcare in Slovenia probably facilitates the coordination of care, which is not the case in Belgium. The financing and organization of primary practices in Belgium was identified as a barrier to the implementation of task delegation between health professionals. CONCLUSIONS: This study allowed formulating some important concepts for future healthcare for non-communicable diseases at the level of primary healthcare. The results could provide useful insights for other countries with similar health systems.

Scale-up integrated care for diabetes and hypertension in Cambodia, Slovenia and Belgium (SCUBY): a study design for a quasi-experimental multiple case study.

Health systems worldwide struggle to manage the growing burden of type 2 diabetes and hypertension. Many patients receive suboptimal care, especially those most vulnerable. An evidence-based Integrated Care Package (ICP) with primary care-based diagnosis, treatment, education and self-management support and collaboration, leads to better health outcomes, but there is little knowledge of how to scale-up. The Scale-up integrated care for diabetes and hypertension project (SCUBY) aims to address this problem by roadmaps for scaling-up ICP in different types of health systems: a developing health system in a lower middle-income country (Cambodia); a centrally steered health system in a high-income country (Slovenia); and a publicly funded highly privatised health-care health system in a high-income country (Belgium). In a quasi-experimental multi-case design, country-specific scale-up strategies are developed, implemented and evaluated. A three-dimensional framework assesses scale-up along three axes: (1) increase in population coverage; (2) expansion of the ICP package; and (3) integration into the health system. The study includes a formative, intervention and evaluation phase. The intervention entails the development and implementation of an improved scale-up strategy through a roadmap with a minimum dataset to monitor proximal and distal outcomes. The SCUBY project is expected to result in three different roadmaps, tailored to the specific health system and country context, to progress scale-up of the ICP along three dimensions. These roadmaps can be adapted to other health systems with similar typology. Implementation is expected to increase the number of well-controlled patients with type 2 diabetes and hypertension in Cambodia, to reduce inequities in care and increase patient empowerment in Belgium and Slovenia.

Clinicopathological Parameters in Patient Selection for Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy for Colorectal Cancer Metastases: A Meta-analysis.

OBJECTIVE: To improve patient selection for cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) by evaluating various preoperatively assessable clinicopathological parameters as markers for survival after CRS and HIPEC. SUMMARY BACKGROUND DATA: Peritoneal metastases (PMs) originating from colorectal cancer are treated with CRS and HIPEC. Despite increasing survival, high morbidity and mortality warrant selection of patients with optimal benefit from this treatment. Many studies report a number of variables to be associated with survival after CRS and HIPEC, but no definitive analysis has been made to validate various markers. METHODS: In concordance with PRISMA guidelines, we performed a literature search encompassing 4110 articles to select 50 articles that reported the influence of 1 or more clinicopathological variables on overall survival after CRS and HIPEC. In absence of RCTs, 25 cohort studies could be used to perform a meta-analysis on 10 prognostic variables. RESULTS: We determined that concurrent liver metastasis, lymph node metastasis, Eastern Cooperative Oncology Group score, tumor differentiation, and signet ring cell histology are all negative prognostic variables on overall survival after CRS and HIPEC. Conversely, sex and location of primary could not be validated as prognostic markers. More research is required to make definitive conclusions about neoadjuvant chemotherapy, onset of PMs, and mucinous histology. CONCLUSIONS: Current clinical practice, which selects patients based on extraperitoneal metastasis, lymph node stage, performance status, and tumor histology, is validated by our pooled analysis. Our data merit further research into neoadjuvant chemotherapy in the setting of CRS and HIPEC for PMs.
