Many patients receive oral anticoagulation for reduced stroke risk in atrial fibrillation or as treatment or prevention of venous thromboembolism. Oral factor Xa inhibitors (oral FXaI, eg, apixaban, edoxaban or rivaroxaban) are commonly prescribed for this indication. Dabigatran, an oral direct thrombin inhibitor, is similarly approved. In vitro and animal model evidence suggests that dabigatran also has direct effects on Staphylococcus aureus virulence and infection. Observational data have shown that dabigatran users are less likely to develop S. aureus bacteremia (SAB), and a small randomised controlled trial showed that dabigatran has anti-S. aureus effects when compared with low molecular weight heparins during bloodstream infection. We seek to answer whether dabigatran is superior to the oral FXaIs in achieving better SAB outcomes among patients who independently require oral anticoagulation. We report the intervention-specific protocol, embedded in an adaptive platform trial.
The S. aureus Network Adaptive Platform (SNAP) trial [NCT05137119] is a pragmatic, randomised, multicentre adaptive platform trial that compares different SAB therapies for 90-day mortality rates. For this intervention (‘Dabi-SNAP’), patients receiving therapy with an oral FXaI will be randomised to continue as usual or to change to dabigatran as of the next scheduled dose. All subjects will receive standard of care antibiotics and/or antibiotics allocated through other active domains in the platform. As the choice of anticoagulant may not demonstrate large differences in mortality, a ranked composite of death and adverse outcomes (Desirability of Outcome Ranking, or DOOR) was chosen as the primary outcome.
The study is conditionally approved by the research ethics board of the McGill University Health Centre: identifier 2025-10900. Trial results will be published open access in a peer-reviewed journal and presented at a global infectious disease conference. The trial is registered at clinicaltrials.gov with the identifier NCT06650501.
Osteogenesis imperfecta (OI) is the most common inherited cause of bone fragility (approximately 1 in 16 000). People with OI suffer bone fragility causing fractures, pain and deformity; sarcopenia causing fatigue and poor endurance; aortic root dilatation and hearing loss. No drug currently has market authorisation to treat OI in Europe. Current standard-of-care is multidisciplinary, with pharmacological interventions—primarily bisphosphonates—directed at increasing bone mass; however, such interventions are of equivocal efficacy. The structural damage that can accumulate as a result of repeated fractures over time may not be reversible. The lack of a treatment with clearly defined efficacy in terms of reducing fracture frequency or the sarcopenia, that is increasingly recognised in this condition, leads to the consideration of alternatives based on what is known about the molecular pathophysiology of the condition. For reasons that are currently unclear, transforming growth factor beta (TGFβ) pathway signalling is increased in OI, and both studies in mouse models and more recently also in humans suggest that reducing TGFβ pathway signalling could be of benefit in OI. This demonstrator project tests the hypothesis that losartan, an antihypertensive agent known to reduce circulating TGFβ, will reduce bone turnover and bone loss and have a positive effect on muscle function and quality of life in adults and older adolescents with OI.
This is a phase 2/pilot, open-label, dose-escalating study. This study aims to identify the effective dose for losartan in this population to inform the design of a pivotal phase III study. The study aims to recruit 30 adolescents and adults aged 16 years and above with OI across secondary care study sites in the UK and Italy. Participants will be recruited from the patient populations attending for treatment of OI at the participating hospital sites or referred by clinicians at the Participant Identification Centres (PIC sites). Participants will be randomised to one of three ‘final doses’—25, 50 or 75 mg losartan once daily. All participants will start on 25 mg once daily. Those assigned to higher ‘final doses’ will increase in 25 mg once daily increments on day 8 and day 15 following safety assessments. The primary outcome measures are to establish the effective dose of losartan in OI patients, based on maximal reduction in the bone resorption marker carboxy-terminal crosslink of type I collagen telopeptide (CTX) over the 24-week period of the study.
Secondary outcome measures are to determine the changes in proxy efficacy outcomes for bone (turnover, mass, architecture and strength) using blood tests, high-resolution peripheral quantitative CT (HRpQCT), dual-energy X-ray absorptiometry (DXA) and muscle (strength) using the ‘Timed Up and Go’ test. In addition, the changes in quality of life, including pain and fatigue, will be evaluated by using a disease-specific tool (OI-QOL) and a validated generic tool (EQ-5D-5L-VAS).
In the UK, the study protocol and amendments have been approved by the London Bridge Research Ethics Committee (REC reference: 23/LO/015) and by the Medicines and Healthcare products Regulatory Agency (MHRA). In Italy, the study protocol and amendments have been approved by the Italian and European ethics and regulatory authorities (Clinical Trials Information System European Union (CTIS EU) portal according to EU Regulation 536/2014). Final version of study protocol: Version 3.2, 05.03.2025. Final results will be disseminated in peer-reviewed journals through local OI, orthopaedic and other relevant clinical networks and at national and international meetings. Sheffield Children’s National Health Service Foundation Trust (UK) and Istituto di Ricovero e Cura a Carattere Scientifico (IRCCS) Istituto Ortopedico Rizzoli (Italy) are the joint study sponsors.
ISRCTN (ISRCTN13317811).
Pathology of the long head of the biceps tendon (LHBT) frequently accompanies rotator cuff tears, with tenotomy and tenodesis often being used to address this pathology. While meta-analyses report comparable functional outcomes between these techniques, tenotomy is linked to higher rates of Popeye deformity, whereas tenodesis is more technically demanding and might involve extra material. A novel self-locking tenodesis technique aims to reduce deformity risk while being a simpler alternative to the conventional tenodesis procedure; however, comparative evidence is currently limited.
This single-centre, patient-blinded randomised controlled trial will enrol 100 patients aged ≥40 years with reparable, non-traumatic, full-thickness supraspinatus and/or infraspinatus and/or subscapularis tendon tears undergoing arthroscopic repair from January 2025 until January 2027. Key exclusion criteria include massive or irreparable tears, advanced glenohumeral osteoarthritis and prior shoulder surgery. Participants will be randomised to either 360 double lasso loop tenodesis or self-locking tenodesis. The primary outcome is the Constant score at 1 year, with a predefined non-inferiority margin of 10 points. Secondary outcomes include American Shoulder and Elbow Surgeons score, simple shoulder value score, LHB score, cosmetic appearance, pain scores and radiographic tendon migration. Statistical non-inferiority will be assessed using a one-sided t-test.
The study protocol received approval from the National Ethical Review Board in France (CPP Sud-Est V) and was registered at ClinicalTrials.gov. The results will be disseminated through publication in a peer-reviewed journal.
In 2023, 21% of deaths occurred in residential aged care facilities (RACFs), a setting expected to play an increasing role in palliative and end-of-life care (PEoLC). General practitioners (GPs) oversee and deliver PEoLC in residential and nursing homes, yet little is known about their practice. We conducted a systematic review of the published evidence concerning how GPs provide this care: what they do and the quality, challenges and facilitators of that care.
Systematic review and narrative synthesis using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses.
Medline, Embase, CINAHL, PsycINFO, Web of Science, Scopus and NHS Evidence and grey literature via Google Scholar were searched through 9 October 2024.
We included studies presenting new empirical data from qualitative, quantitative or mixed methods, were published in the English language and conducted in the UK, the European Union, Australia, New Zealand and Canada. We excluded studies with no new empirical data, discussion papers, conference abstracts, opinion pieces, study participants under 18 years old and in care settings other than RACF.
One independent reviewer used standardised methods to search and screen study titles for inclusion. This reviewer assessed all abstracts of the included papers, and a second independent reviewer screened 60% of the abstracts to validate inclusion. Risk of bias was assessed using Gough’s Weight of Evidence assessment. Thematic analysis was used to describe the contents of the included papers; a narrative synthesis approach was taken to report the findings at a more conceptual level.
The search identified 5936 titles: 35 papers were eligible and included in the synthesis. This is a nascent evidence base, lacking robust research designs and characterised by small sample sizes; the results describe the factors observed to be important in the delivery of care. Care provision is extremely variable; no models of optimal care have been put forward or tested. Challenges to care provision occur at every level of the care system. At macro level, service-level agreements and policies vary: at meso level, team-working, communication technology solutions and equipment availability vary: at micro level, GPs’ interests in providing PEoLC vary as does their training. No study addresses residents’ and relatives’ experiences and expectations of GPs' involvement in PEoLC in RACFs.
The limited evidence base highlights that GP care at end of life for RACF residents varies greatly, with enablers and challenges at all levels in the existing care systems. Little research has examined GP PEoLC for RACF residents in its own right; insight is derived from studies that report on this issue as an adjunct to the main focus. With national policies focused on moving more PEoLC into community settings, these knowledge deficits require urgent attention.
Ambulatory care sensitive conditions (ACSCs) are conditions for which the provision of timely and skilled primary care can reduce risks of hospitalisation when preventing, treating or controlling a disease. For this reason, hospitalisations for ACSC have been commonly employed by health systems as an indicator of effectiveness for the primary level of care. This study aims to evaluate whether the provision of primary care services by physicians with residency training in family medicine is associated with rates of general hospitalisations for ACSCs in the Brazilian Unified Health System network in the city of Belo Horizonte, Brazil.
Longitudinal ecological study using a Generalised Linear Model for Gamma-distributed variables.
Primary healthcare centres in Belo Horizonte, Brazil, from January 2017 to December 2021, aggregated at the primary healthcare centres level.
Data aggregated at the primary healthcare centre level, encompassing socioeconomic, professional and health-related variables.
Incidence rates of hospitalisations for ACSCs, adjusted for age and sex.
After adjusting for age, sex and socioeconomic variables using the Health Vulnerability Index, a higher concentration of family physicians was significantly associated with a lower incidence of hospitalisations for ACSCs. If all physicians in the primary care network were family physicians, compared with a scenario in which none were, an estimated 11.89% reduction in hospitalisations would be expected (95% CI 7.3% to 16.3%, p
The findings suggest that specialisation in family medicine positively impacts health outcomes by reducing hospitalisations for ACSCs. These results can inform the development of evidence-based public policies to enhance primary care effectiveness.
Real-world data and patient-reported outcomes in diabetes in Emilia–Romagna is a multi-centric observational cohort study aimed at improving diabetes care in the Emilia–Romagna region, by exploring trends and predictors of clinical and psychological parameters in a large population of people with diabetes, during and after the COVID-19 pandemic.
The study has a mixed retrospective/prospective design. The retrospective component involves computerised data linkage of administrative and clinical data from the local health authorities of Romagna and Reggio Emilia, and the University Hospital of Parma, covering a population of approximately 100 000 prevalent cases with diabetes, followed throughout the years 2019–2024. The selection of data items collected in the reference time frame is based on the International Consortium for Health Outcomes Measurement (ICHOM) standard set for diabetes, including clinical, lifestyle, social and healthcare service measurements. The prospective component includes primary data collection of indicators of psychological well-being through the WHO-5 Well-Being Index, diabetes distress using the Problem Areas In Diabetes-Short Form and depression through the Patient Health Questionnaire-9, measured at 0–6 months in an overall sample of 455 people with type 2 diabetes. Statistical analysis will include descriptive analysis and multivariate logistic regression using a two-step federated approach.
The study has obtained ethics approval from the Ethics Committee of Romagna and the Ethics Committee of Area Vasta Emilia Nord. The results of the study will be published in scientific journals to evaluate quality and outcomes of diabetes care across the region.
This study aims at documenting the frequency of reported abuse, stigma and discrimination and exploring the perspectives for improving the quality of maternal-newborn care (QMNC) of migrant mothers’ reporting abuse, stigma or discrimination.
Mixed methods multicentre cross-sectional study.
All maternal facilities (tertiary and secondary levels of care, n=9) from Friuli-Venezia Giulia region, Northeast Italy, between November 2019 and January 2022 in Northeast Italy.
874 migrant and 3968 non-migrant women answering a validated WHO Standard-based questionnaire after birth.
Frequency of reported abuse, stigma and discrimination during facility-based childbirth was calculated and compared with those of non-migrant mothers. Thematic analysis was conducted on eight open questions, using WHO Standards as a framework for the analysis.
Among migrant women, 84 (9.6%) reported some type of abuse, stigma and discrimination, a frequency similar to non-migrant women (9.8%, p=0.880). The most frequently reported was verbal abuse (87.7%), followed by stigma and discrimination (15.1%). Most women (86.9%) provided at least one comment, with a frequency comparable to non-migrant women (p=0.076). Among a total of 327 comments, 104 (31.8%) were practical suggestions for improving QMNC. Experience of care was the domain with the highest frequency both of negative (64.9% of negative comments) and positive comments (51.7% of positive comments) and with the highest frequency of suggestions for improving QMNC (52.9% of suggestions). Overall, suggestions mainly focused on strengthening healthcare professionals’ communication skills, allowing companionship during childbirth, increasing healthcare professionals’ availability and timely support.
This study shows that both migrant and non-migrant mothers are exposed to abuse, stigma and discrimination during childbirth, and that both are willing to provide practical suggestions, which should be used for planning actions to improve QMNC.
Patients with acute psychiatric symptoms are often referred to the emergency department (ED) for medical evaluation to exclude medical causes before psychiatric admission. The absence of a prospectively validated medical screening tool leads to wide practice variation. This study aims to develop a new, evidence-based and consensus-based medical screening tool through a collaborative, interdisciplinary, international Delphi approach.
This modified Delphi study will include representatives from emergency medicine and psychiatry societies across four continents, as well as patient representatives with prior experience of medical screening in the ED. A minimum sample size of 24 participants is planned to account for potential dropouts. The Delphi procedure consists of four rounds. Round 1 will present current evidence and identify key items for the new medical screening tool. Round 2 will evaluate and refine statements from Round 1. Round 3 will seek consensus on the variables to be included in a medical screening tool. In Round 4, hypothetical clinical vignettes will be used to assess the agreement on the recommendations of the newly developed medical screening tool in order to test for content and construct validity. Surveys will be conducted via Research Electronic Data Capture (REDCap), with participants rating statements on a 6-point Likert scale. Response stability will be evaluated using the intraclass correlation coefficient, and consensus defined as ≥80% agreement. Results will be reported according to the ACcurate COnsensus Reporting Document guidelines and the Guidance for Reporting Involvement of Patients and the Public 2 short form.
The Ethics Committee of Northwestern and Central Switzerland exempted the project from committee approval under the Human Research Act on 11 September 2024. Written consent will be obtained from all participants. Results of this study will be summarised as a medical screening tool which will be validated in a prospective, multicentre study in a second step.
To understand why patients with chronic kidney disease (CKD) may not be treated according to international guidelines for myocardial infarction (MI).
Multicentre qualitative interview study. Interviews were analysed using reflexive thematic analysis approach as outlined by Braun and Clarke to generate themes associated with MI treatment decision-making for, and by, patients with CKD.
Four National Health Service hospital centres in the UK (February 2022 to July 2024).
A purposive sample of 46 participants (patients and clinicians). Clinicians (n=32) were senior doctors-in-training or consultants in cardiology, nephrology, acute or emergency care or cardiac surgery. Patient participants (n=14) had CKD, defined as an estimated glomerular filtration rate 2, or receipt of kidney replacement therapy (KRT).
Despite expressing strong views regarding their health priorities, patients reported minimal involvement in treatment decision-making. Decision-making by clinicians was driven by the desire to avoid causing harm to patients by ‘active’ treatment initiation. In general, despite the concept of evidence-based medicine being widely accepted, there remained scepticism of guidelines or epidemiological data, especially in the light of personal adverse experiences or anecdotes. Clinicians described how, in the absence of collaborative decision-making and a clinical safety-net for managing treatment complications, they tended to make conservative treatment decisions for patients with CKD.
Interventions to foster teamworking between specialists and ensure adequately resourced specialist clinical service safety-nets may improve access to treatments for MI for people with CKD. Intervention development and evaluation should follow to determine if outcomes for people with CKD and MI can be improved.
A substantial number of patients with major depressive disorder experience non-remission despite treatment with psychotherapy and several antidepressant drugs. This has increased the interest in new treatment strategies, including non-invasive brain stimulation methods. This randomised controlled trial examines a new treatment method using transcranial-pulsed electromagnetic fields (T-PEMF) delivered via a MoodHeadBand (MHB). The main study objective is to examine the antidepressant effect of T-PEMF on moderate to severe depression.
A double-blinded, randomised (1:1), sham-controlled trial with 96 participants diagnosed with moderate to severe depression without psychotic symptoms, recruited from Psychiatric Center Copenhagen. Participants receive daily 30 min at-home T-PEMF or sham treatment for 8 weeks with the MHB. Depressive symptomatology is examined using the Inventory of Depressive Symptomatology (Self-Report) (primary outcome) and Hamilton-D-17 Items Rating Scale at baseline and treatment completion. Cognitive functions are examined using a battery of emotion-laden and non-emotion-laden tests at baseline, after 1 week and at treatment completion. The participants fill out the Quick Inventory of Depressive Symptomatology (Self-Report) and sleep logs weekly. Summary statistics, generalised linear models, proc mixed models, mixed model repeated measures and Kaplan-Meier analysis will be applied as appropriate to analyse data on depressive symptoms, cognition and sleep.
The Danish Medicines Agency (CIV-23-01-041987) and the Medical Research Ethics Committee (2215332) have approved the trial. The project concurs with the EU directive for medical devices 2017/745 of 5 April 2017 and the ISO 14155 standard. Participants give written informed consent before any trial-related activities. Results will be published in peer-reviewed journals and presented at relevant conferences.
Suicide is a leading cause of preventable death worldwide. Evidence supports the impact of providing active contact for individuals who have attempted suicide. The current systematic review and meta-analyses aim to investigate the effects of suicide prevention strategies implemented through remote and synchronous technology-based interventions.
Systematic review, narrative synthesis and meta-analysis.
Electronic databases (PubMed, PsycINFO, Scopus and Web of Science) and grey literature sources (ClinicalTrials.gov and Google Scholar) were searched until December 2024.
Eligible articles assessed suicide prevention interventions for participants over 12 years with prior suicidal behaviour. Eligible study designs included randomised controlled trials and non-randomised clinical trials published in English or Spanish.
Screening, selection process, data extraction and risk of bias assessment were performed independently by two reviewers. Data on suicide-related factors and adherence to treatment were extracted. Meta-analyses were conducted to determine effect sizes (Hedges’ g) for suicidal ideation, risk ratios (RR) for suicide attempts and Peto odds ratios (OR) for suicide. Heterogeneity was assessed using the Cochrane’s Q test, tau2 statistic and I2 value. Publication bias was investigated employing funnel plots and Egger’s test.
A total of 28 studies, comprising 10 015 participants in the intervention group and 10 726 in the comparison group, were included in the systematic review and meta-analyses. Synchronous remote-based interventions were effective in preventing repeated suicide attempts at 1 month (RR 0.73, 95% CI 0.62 to 0.85, I2=0.0%, Q=0.70, tau2=0.00), 6 months (RR 0.56, 95% CI 0.34 to 0.95, I2=85.4%, Q=54.92, tau2=0.36) and 12 months (RR 0.68, 95% CI 0.49 to 0.96, I2=87.6%, Q=72.63, tau2=0.27). Additionally, these interventions were associated with a reduction in suicide-related deaths at 18 months (Peto OR 0.18, 95% CI 0.08 to 0.44, I2=0.0%, Q=0.03, tau2=0.00). Effects on suicidal ideation were not statistically significant at any time point (Hedges’ g –0.07 to –0.28, I2=0.0 to 69.3%, Q=1.16 to 7.38, tau2=0.00 to 0.14).
Synchronous remote-based interventions demonstrate a potential benefit in preventing suicide attempts and deaths by suicide and may serve as an adjunct to usual treatment; however, the effect on suicidal ideation appears limited. The observed heterogeneity warrants caution when interpreting these findings. Future research should prioritise methodological enhancements to improve the quality and consistency of evidence, as well as investigate the mediating processes underlying their effectiveness in reducing suicidal behaviour.

Inherited retinal diseases (IRDs) are a broad range of diseases associated with abnormalities/degeneration of retinal cells. We aimed to identify the top 10 Australian research priorities for IRDs to ultimately facilitate more meaningful and potentially cost-effective research.
We conducted a James Lind Alliance priority setting partnership that involved two Australian-wide surveys and online workshops.
Australia-wide.
Individuals aged 16 years or older were eligible to participate if they had an IRD, were caregivers of an individual with an IRD or were health professionals providing care to this community.
In Survey 1, we gathered participants’ unanswered questions about IRDs. We grouped these into summary questions and undertook a literature review to verify if they were truly unanswered (ie, evidence uncertainties). In Survey 2, participants voted for the uncertainties that they considered a priority. Top-ranked uncertainties progressed for discussion and final prioritisation in two workshops.
In Survey 1, we collected 223 questions from 69 participants. We grouped these into 42 summary questions and confirmed 41 as evidence uncertainties. In Survey 2, 151 participants voted, with the 16 uncertainties progressing to final prioritisation. The top 10 priorities, set by the 24 workshop participants, represented (1) treatment/cure; (2) symptoms and disease progression; (3) psychosocial well-being and (4) health service delivery. The #1 priority was for treatment to prevent, slow down or stop vision loss, followed by the #2 priority to address the psychological impact of having an IRD.
The top 10 research priorities highlight the need for IRD research that takes a whole-person, systems approach. Collaborations to progress priorities will accelerate the translation of research into real-world benefits.
We evaluated the performance of risk models that incorporate ambulatory ECG data and clinical information for prediction of healthcare expenditures related to heart failure (HF) and stroke events in treated and untreated patients.
A retrospective cohort study of Medicare patients who underwent Zio XT ambulatory monitoring in the USA was conducted between 2014 and 2020.
14-day ambulatory ECG data and claims data were evaluated in the study sample which included 89 923 patients in the HF hospitalisation group, 75 870 in the new-onset HF group and 90 159 in the stroke hospitalisation group. Predictive models for new-onset HF, HF hospitalisation and stroke hospitalisation were generated using LASSO Cox regression with ambulatory ECG variables and components of the CHA2DS2-VASc. For each outcome, we scored patients using standardised linear predictors from three composite risk models, and we evaluated the association between risk score and total Medicare cost.
The following hazard ratios per one SD increase in the new risk score were observed for the model that included all CHA2DS2-VASc components and ECG variables: HF hospitalisation in treated 2.94, 95% CI 2.75 to 3.15; new-onset HF in treated 1.84, 95% CI 1.75 to 1.93; HF hospitalisation in untreated 3.51, 95% CI 3.23 to 3.82; and new-onset HF in untreated 1.92, 95% CI 1.85 to 2.00. Risk scores generated by the model were also predictive of Medicare cost in both treated and untreated patients, with patients in the high-risk category for all outcomes having the greatest Medicare costs during 1 year of follow-up.
Integrating arrhythmia data from ambulatory ECG monitoring into clinical risk models allows for better prediction of healthcare utilisation and cost in both treated and untreated patients at high risk for HF and stroke events.
Combined vascular endothelial growth factor/programmed death-ligand 1 blockade through atezolizumab/bevacizumab (A/B) is the current standard of care in advanced hepatocellular carcinoma (HCC). A/B substantially improved objective response rates compared with tyrosine kinase inhibitor sorafenib; however, a majority of patients will still not respond to A/B. Strong scientific rationale and emerging clinical data suggest that faecal microbiota transfer (FMT) may improve antitumour immune response on PD-(L)1 blockade. Early trials in melanoma with FMT and reinduction of immune checkpoint blockade (ICI) therapy in patients with anti-PD-1-refractory metastatic melanoma were reported in 2021 and demonstrated reinstatement of response to ICI therapy in many patients. Due to anatomical vicinity and the physiological relevance of the gut-liver axis, we hypothesise HCC to be a particularly attractive cancer entity to further assess a potential benefit of FMT in combination with ICI towards increased antitumour immunity. Additionally, HCC often occurs in patients with liver cirrhosis, where liver function is prognostically relevant. There is evidence that FMT may increase hepatic function and therefore could positively affect outcome in this patient population.
This prospective, multicentre, randomised, placebo-controlled, double-blind phase II clinical trial has been designed to assess immunogenicity and safety of FMT via INTESTIFIX 001 combined with A/B in advanced HCC in comparison to A/B with placebo. Primary endpoints are measured as tumour CD8+ T cell infiltration after 2 cycles of treatment with vancomycin, A/B+INTESTIFIX 001 in comparison to vancomycin-placebo, A/B+INTESTIFIX 001-placebo and safety of the therapeutic combination in advanced HCC. INTESTIFIX 001 is an encapsulated FMT preparation by healthy donors with a high alpha-diversity in their gut microbiome for oral administration, manufactured by the Cologne Microbiota Bank (CMB). Sample size was calculated to achieve a specific expected accuracy for the primary immunological endpoint. 48 subjects will be randomised to reach a goal of 42 usable measurements in the modified intention-to-treat set. Subjects will be randomised in a 2:1 ratio to A/B or placebo (28 A/B, 14 placebo).
The study was approved by ethics committee review and the German Federal Ministry of Drugs and Medical Devices. The trial is registered under EU CT no. 2023-506887-15-00. The outcome of the study will be disseminated via peer-reviewed publications and at international conferences.
Childhood cancer accounts for a significant proportion of global childhood mortality, especially in low-income and middle-income countries (LMICs). Unlike many adult malignancies, primary prevention of childhood cancers is not possible. Improving survival requires a two-pronged strategy: earlier diagnosis and effective treatment. Our study aims to establish the feasibility, clinical and implementation effectiveness of an adapted early warning signs and symptoms (EWSS) intervention in Cameroon and Kenya. It will equip healthcare workers, Ministry of Health (MOH) representatives and National Cancer Institute leaders with evidence-informed guidance on implementing context-adapted interventions to improve the early detection and referral of childhood cancers in these countries.
The study is a quasi-experimental, hybrid type 2 implementation effectiveness study based on a Ghanaian adaptation of the ‘Saint Siluan’ EWSS campaign. Our protocol proposes context-specific adaptation and evidence-based implementation of the EWSS intervention through iterative engagement with country-level implementation teams to train healthcare workers and improve referral pathways for earlier childhood cancer diagnoses in each study country. Training effectiveness will be measured through pretraining and post-training tests of knowledge and application, as well as training satisfaction surveys. Clinical effectiveness will be assessed by using a REDCap database to track the number of newly diagnosed childhood cancer cases in the study regions and counties, healthcare timelines and paths to diagnosis, and the stage and proportion of metastatic disease at diagnosis. Implementation effectiveness will be evaluated through interviews with senior and mid-level health system partners and clinicians, tracking fidelity to the implementation process as laid out in The Implementation Roadmap Workbook, and analysis of meeting minutes from monthly local implementation team meetings.
This study has received ethical approval from The Hospital for Sick Children (REB # 1000080092) and all participating sites. We have received National Ethical Clearance from the Cameroon Ethical Board (#1699) and Regional Administrative Authorizations from our piloting regions (Centre and West). We have also received ethical clearance from Kenyatta National Hospital (KNH) (ERB# KNH-ERC/RR/955) and our National Commission for Science, Technology and Innovation in Kenya licence from the counties we are piloting in Kenya. As clinical data will be collected from existing health registries and patient charts, patient consent will not be required; however, we will obtain consent from all members of the leadership implementation teams and operational implementation teams for their participation in the implementation meetings and from all individuals participating in the semistructured interviews. We will disseminate findings to build awareness and share findings among various target audiences: (1) key county and regional parties (eg, clinical societies, advocacy groups, country MOHs and regional bodies such as the East African Community, Economic Community of West African States); (2) international bodies such as the WHO; and (3) the academic community.
