The UK Health Security Agency and the National Health Service England (NHSE) led a hepatitis C virus (HCV) patient re-engagement exercise beginning in 2018, which entailed sharing public health surveillance data with NHSE Operational Delivery Networks (ODNs) in England. The ODNs used the data to contact and offer testing and treatment to people historically diagnosed with HCV, but who did not have evidence of successfully clearing the virus. A quantitative evaluation found that of 55 329 individuals whose details were shared with ODNs, around 13% had treatment after the exercise commenced. This qualitative evaluation aims to identify the barriers and facilitators to the re-engagement exercise as reported by ODN staff.

Semistructured interviews. The topic guide and analysis were guided by the Theoretical Domains Framework, using a combined deductive framework and inductive thematic analysis approach.

21 staff from 13 ODNs. The sampling frame was designed to capture participants from all regions of England and with varied outcomes from the re-engagement exercise.

Interviewees reported the most barriers in environmental context and resources (including staffing limitations, interruptions during COVID-19, restricted laboratory access), and social influences (with limited responses from general practitioners and patients). Interviewees discussed whether it was appropriate for ODNs and individual staff to be assigned the data validation work and reported some stress and memory/attention barriers due to the volume of the exercise. They had varied beliefs about the consequences of the exercise, with most believing it was worthwhile due to treatment yield, lessons learnt and confirmation that some people had cleared the virus. Further facilitators included the ODN goals fitting with the exercise, and regional resources such as patient databases. Interviewees also reported adaptations to the exercise that facilitated patient contact, and their ongoing work to re-engage patients emphasised outreach partnerships and peer support.

The evaluation revealed insights into methods for re-engaging patients and of sharing and using public health data to support clinical practice. Government support and funding provision for regionally tailored holistic re-engagement approaches, alongside enhancements to health surveillance data, could enable barriers to re-engagement to be overcome.

Breast cancer is common and women requiring mastectomy will be offered a breast reconstruction if they are surgically suitable candidate. Breast reconstruction can be performed at the same time as the mastectomy (immediate) or delayed to a second operation after cancer treatments. The reconstruction can either use the patients’ own tissue to make the breast (autologous) or use a prosthesis to make the breast in the form of a fixed or expandable volume implant (implant-based breast reconstruction, IBBR). Immediate breast reconstruction on top of the chest wall muscles (prepectoral) is performed worldwide. This operation involves the use of a synthetic or biological mesh placed around the implant under the skin. Increasingly, surgeons are performing this technique without the use of mesh. Both techniques, with and without mesh, have not been compared in a head-to-head randomised controlled trial (RCT); therefore, surgeons and patients do not have high quality data to guide their decision making in this area.

UK-based pragmatic multicentre randomised controlled feasibility trial. The primary aim is to determine the feasibility of a definitive RCT comparing the clinical and cost-effectiveness of no-mesh versus mesh-assisted prepectoral breast reconstruction. Secondary objectives will explore patient understanding of mesh and willingness to be randomised within an RCT; determine if it is possible to collect data to inform a future economic analysis on the use of mesh in breast reconstruction and determine the feasibility of measuring breast biomechanics pre-surgery and post breast reconstruction surgery. Total number of patients to be included: 40 (20 per arm).

This study aims to develop a methodology to retrieve, harmonise and evaluate the completeness of national body mass index (BMI) data from linked electronic health record (EHR) sources to build a longitudinal research-ready data asset (RRDA).

A longitudinal study of BMI records spanning 23 years (1 January 2000 to 31 December 2022) from four data sources.

The national BMI RRDA is created within the Secure Anonymised Information Linkage (Databank), encompassing the entire population of Wales, UK.

We built a methodology that provides a reproducible framework for extracting and harmonising BMI data from four major linked EHRs across two age groups: children and young people (CYP; 2–18 years old) and adults (19 years and older). The methodology is adaptable across different trusted research environments. We evaluated the completeness and retention of records over 1-, 5- and 23-year periods by calculating the proportion of missing data relative to each year’s population.

We retrieved 53.4 million records for 3.2 million individuals across Wales from 1st January 2000 to 31 December 2022. Among these, 3% of CYP and 34% of adults had repeat BMI measurements recorded over periods ranging from 5 to 23 years. Throughout the entire population of Wales during this period, 49% of CYP and 26% of adults had at least one BMI reading recorded, resulting in a missingness rate of 51% for CYP and 74% for adults. Preserving BMI information by retaining the most recently recorded BMI over 1-, 5- and 23-year intervals from 2022 showed coverage rates of 10%, 33% and 68%, respectively, for CYP, and 25%, 51% and 73%, respectively, for adults.

Our findings highlight substantial variations in BMI data availability and retention across CYP and adults, as well as time periods within EHR in Wales. Wider adoption of this approach can enhance standardised approaches in using accessible measures like BMI to assess disease risk in population-based studies, strengthening public health initiatives and research efforts.

Sexual and gender-based violence can have long-term impacts on the physical and mental health of survivors, with demonstrated impairments to immune, endocrine and nervous systems, and increased risk of chronic conditions such as cardiovascular disease, depression and post-traumatic stress. Moreover, survivors commonly experience low self-efficacy and lack of perceived control over their lives. Creating space for survivors to feel empowered through a multidimensional approach to health promotion, considering both physical and psychological influences on health, is necessary to reduce chronic disease.

In this type II hybrid effectiveness-implementation cluster randomised controlled trial, we evaluate a novel peer-led intervention that combines expressive writing and trauma-informed boxing, Left Write Hook, against trauma-informed boxing alone—an intervention approach that is currently accessible in the community and has been shown to improve both mental and physical health. 20 clusters of 8–10 adults (n=150) with a self-reported history of child sexual abuse or other gender-based violence will be recruited in Melbourne, Australia, through health services and the community. Clusters will be randomly assigned to complete either 8x weekly group sessions of Left Write Hook (intervention) involving both expressive writing and trauma-informed boxing led by a trained peer facilitator, or 8x weekly group boxing sessions led by a trauma-informed boxing facilitator (control). Implementation will be evaluated against the PRISM Reach Effectiveness Adoption Implementation Maintenance (RE-AIM) framework. The primary effectiveness outcome is change in self-efficacy from preintervention to postintervention (8 weeks). Secondary effectiveness outcomes are changes in symptoms of complex post-traumatic stress disorder, trauma-related cognition and indicators of physical fitness (strength, flexibility, aerobic fitness and balance). Assessment will be completed online or over the phone with a member of the research team at preintervention (0 weeks), postintervention (8 weeks) and at 1 month following completion of the intervention (12 weeks). The primary implementation outcome is the fidelity of the train-the-champion implementation strategy for intervention training and delivery, and the secondary implementation outcome is adoption of the intervention and training delivery.

Ethical approval was received from the Human Research Ethics Committee of The University of Melbourne (2024-28998-60131-11) and the Alfred Hospital Ethics Committee (110810). Results will be disseminated via publication in a peer-reviewed journal, and data will be made available via Open Science Framework at the conclusion of the trial.

Poor chest health is the leading cause of early mortality in children with cerebral palsy (CP). It is also the most common reason to seek healthcare, accruing significant costs and reducing quality-of-life for children and families. Clinical trials examining chest health interventions in CP are characterised by inconsistent outcome measures, limiting the capacity for evidence synthesis to inform clinical application. The study aims to develop a core outcome set (COS) and related measurement instruments to assess, monitor and evaluate chest health in children with CP, both in research and routine clinical practice. The COS will reflect the views of children, young people, parent/carers, clinicians and researchers, emphasising under-represented groups in research and those at risk of poorer chest health.

A 3-phase methodology will be conducted in line with the Core Outcome Measures in Effectiveness Trials (COMET) Initiative. (1) Candidate outcomes will be identified through a qualitative evidence synthesis and interviews with key stakeholders. Findings will be mapped to COMET-taxonomy, generating a list of candidate outcomes. (2) An international e-Delphi survey will invite stakeholders to rate the importance of each outcome, followed by a consensus meeting to ratify the COS. (3) A structured review, guided by health measurement taxonomy, will evaluate relevant instruments, with a final meeting to agree on recommended measures for each COS domain.

Ethical approval was provided by the University of Plymouth Research Ethics Committee for the qualitative interview study (ID5116), e-Delphi study and consensus meeting (ID5636). Study findings will be published open access in a peer-reviewed journal and presented at relevant national and international conferences.
