Chronic respiratory diseases (CRDs), such as asthma and chronic obstructive pulmonary disease (COPD), are among the leading non-communicable diseases (NCDs) worldwide. However, diagnosing CRDs in low-income and middle-income countries (LMICs) remains challenging due to limited access to spirometry and trained professionals. Aggravating the burden, CRDs often coexist with other NCDs, increasing healthcare costs, reducing quality of life and elevating mortality. These challenges highlight the need for simple case-finding approaches for CRDs, such as the COPD in Low-Income and Middle-Income Countries Assessment (COLA-6) questionnaire, to support prompt identification and appropriate care within NCD services in LMICs.

To evaluate the discriminative accuracy, feasibility and implementation of the COLA-6 questionnaire in identifying and managing CRDs in Brazilian Primary Healthcare (PHC) services for NCDs.

The Multimorbidity Approach for REspiratory Solutions (MARES) study consists of three work packages to be conducted in PHC services in São Carlos/SP and São Paulo/SP, Brazil.

MARES-1: A cross-sectional observational study enrolling 859 individuals with at least one NCD receiving care in PHC. The COLA-6 questionnaire will be administered by the research team and compared with quality-assured spirometry. The Chronic Airways Assessment Test (CAAT), Asthma Control Questionnaire (ACQ-7) and fractional exhaled nitric oxide (FeNO) will also be assessed. The diagnostic performance of COLA-6 for identifying CRDs—including COPD, asthma, preserved ratio impaired spirometry, restriction and overlaps—will be assessed using area under receiver operating characteristic curves and 95% CIs.

MARES-2: A cross-sectional observational study enrolling 20 healthcare professionals (physicians, physiotherapists, community health agents and nurses) from five PHC services. These professionals will apply the COLA-6 during routine NCD care to a total sample of 1000 patients. Qualitative interviews will be conducted to explore barriers and facilitators to the implementation of COLA-6, using deductive thematic analysis.

MARES-3: A longitudinal, prospective observational study in which patients from MARES-1 and MARES-2 will be reassessed at 6-month follow-up. A total sample of 473 participants with abnormal spirometry, a diagnosis of CRD or high risk for CRDs is expected. Participants will undergo spirometry, and a subset will be interviewed to explore their healthcare experiences through qualitative thematic analysis. Access to diagnostic and treatment services in Brazil will be assessed. Changes in spirometry values, FeNO, CAAT and ACQ-7 scores from baseline to 6 months in patients from MARES-1 will be analysed.

This study has been approved by the Ethics Committees of Federal University of São Carlos and University of Santo Amaro (UNISA). Ethical approval was also granted by the University College London. Results will be disseminated through peer-reviewed medical journals and presentations at international conferences. Results will improve identification of CRDs, addressing a significant gap in current PHC settings.

To evaluate the performance of Ghana’s environmental surveillance (ES) system for poliovirus (PV) detection from 2018 to 2022 using standardised indicators developed by the WHO and the US Centers for Disease Control and Prevention.

A retrospective performance evaluation using 10 key indicators benchmarked against global targets for PV surveillance.

Seven regions across Ghana, participating in the national ES programme implemented under the Global Polio Eradication Initiative.

Wastewater sampling was conducted at designated ES sites, supported by field collection teams and laboratory personnel responsible for sample acquisition, processing and reporting of PV detection results.

Detection rates of PV and non-polio enteroviruses (NPEVs), timeliness of sample collection and reporting, data quality and system stability.

A total of 738 wastewater samples were collected. The system demonstrated high sensitivity, detecting circulating vaccine-derived PV type 2 in 51 (6.9%) of samples, Sabin PV types 1 and 3 in 61 (9.5%) and 114 (17.8%), respectively, and NPEVs in 491 (66.5%) of samples. Over 80% of samples met the recommended 21-day collection-to-reporting time frame. Data quality exceeded the ≥80% threshold, and workflows remained stable throughout the evaluation period.

Ghana’s ES system for PV was found to be flexible, stable and effective in generating high-quality data for early detection and public health response. These findings underscore the system’s critical role in supporting polio eradication efforts and highlight its potential as a model for surveillance in similar settings.

Patient-reported experience measures (PREMs) are measures of patients’ perceptions of care they receive. PREMs are critical in developing and evaluating programmes that aim to improve patient healthcare experiences and quality of care (QoC) according to patient-defined needs. This review aims to map key domains of PREMs across distinct healthcare technical areas and life stages from globally available literature.

A scoping review adapting Arksey and O’Malley’s framework and Joanna Briggs Institute’s guidelines for the conduct of scoping reviews.

Google Scholar, PubMed, WHO, US Academy of Medicine and USAID Momentum.

PREMs literature from electronic repositories of grey and peer-reviewed publications, published in English historically up to September 2023.

Two lead reviewers with support from the technical working group co-created a review framework of healthcare technical areas, life stages and PREMs domains. We screened eligible articles, prioritising reviews except for technical areas with no reviews, where we then selected individual studies. We charted, analysed and synthesised data from 52 eligible articles.

PREMs literature has recently increased, especially in low-income and middle-income countries (LMICs), although studies in high-income countries (HICs) dominate in proportion (n=38; 73.1%). Out of 52 eligible articles, technical areas with most publications were sexual and reproductive health (n=21; 40.4%) and general outpatient care (n=11; 21.2%). Studies in adulthood (n=24; 46.2%) and from pregnancy and birth to postnatal (n=16; 30.8%) were most represented. PREMs studies reported mostly on communication and rapport (n=33; 63.5%) and respect and dignity (n=42; 80.8%) domains. Nearly a quarter (n=12; 23.1%) of the articles included only validated tools; the rest included a combination of validated and unvalidated measures. Of the tools relating to life stages of babies, younger children and older adults, the majority (n=17; 94.4%) included patient proxies.

PREMs, as an important component of QoC measurement, are increasing across several healthcare technical areas and life stages with commonalities and notable distinctions in measurement domains and tools. Evidence on PREMs largely comes from HICs. Evidence on critical, yet sometimes overlooked domains, highlights key QoC implementation gaps. The adaptation and utilisation of PREMs in programmes, especially in LMICs and under-represented technical areas, present opportunities to close the QoC disparities in those settings. Strategic, concerted efforts towards the harmonisation of PREMs tools across multiple life course stages and technical areas are critically needed in high-level quality improvement efforts.

Gestational weight gain (GWG) is an important indicator of maternal nutrition to be monitored during pregnancy. However, there is no evidence-based tool that can be used to monitor it across all geographic locations and pre-pregnancy body mass index (BMI) categories. The WHO is undertaking a project to develop GWG charts by pre-pregnancy BMI category, and to identify GWG ranges associated with the lowest risks of adverse maternal and infant outcomes. This protocol describes all the steps that will be used to accomplish the development of these GWG charts.

This project will involve the analysis of individual participant data (researcher-collected or administrative). To identify eligible datasets with GWG data, a literature review will be conducted and a global call for data will be launched by the WHO. Eligible individual datasets obtained from multiple sources will be harmonised into a pooled database. The database will undergo steps of cleaning, data quality assessment and application of individual-level inclusion criteria. Heterogeneity of maternal weight and GWG will be assessed to verify the possibility of combining datasets from multiple sources and regions into a single database. Generalized Additive Models for Location, Scale and Shape will be applied for the construction of the centile curves. Diagnostic measures, internal and external validation procedures will also be performed.

This project will include an analysis of existing study de-identified data. To be included in the pooled database, each included study should have received ethics approvals from relevant committees. Manuscripts will be submitted to open-access journals and a WHO document will be published, including the GWG charts and cut-offs for application in antenatal care.

The objective of this scoping review is to map out what has been published in the scientific literature on the relationship between climate change-related events and how these overlap with associated changes in resource availability, transactional sex and HIV incidence and prevalence, within fishing communities in the Lake Victoria basin. This objective is informed by the fact that climate change and the associated natural resource strains in the Lake Victoria region have exacerbated existing inequities within fishing communities. Vulnerable populations, especially women, engage in strategies such as transactional sex to cope with the uncertainty of natural resource-dependent livelihoods. This practice greatly increases women’s risk of contracting HIV in this region, with prevalence rates four to five times the national averages. This scoping review will thus show how the existing empirical literature reports on climate change, transformation in natural resources and livelihoods, and transactional sex and HIV in the Lake Victoria region.

Studies that meet the following inclusion criteria will be included: align with at least two of the major concepts of interest, including climate change, transactional sex, HIV/AIDS, Lake Victoria Basin and/or empirical studies; are published in English and after 2012; and focus on the Lake Victoria basin. The scoping review will be guided by the JBI Manual for Evidence Synthesis: Scoping Reviews, supported by the standard principles of Arksey and O’Malley. The specific search strategies to be implemented were developed with guidance from an experienced research librarian to align with the inclusion criteria. The search will be conducted in relevant global databases, with two reviewers screening the results and extracting relevant data points. Finally, results will be reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews flow diagram, and summarised in figures, tables and text.

The scoping review is designed to comprehensively scope the existing literature and document the coverage of linkages between transactional sex, HIV/AIDS and sustainable livelihoods in the context of climate change with a view to informing health systems responses to human health specific to the HIV epidemic.

The proposed scoping review is registered with the Open Science Foundation (OSF), registration number:https://doi.org/10.17605/OSF.IO/9DTW4.

To identify stakeholder perceived challenges and facilitators for implementing a clean fuel and clean stove intervention to reduce household air pollution and hypertension in Lagos, Nigeria.

Qualitative study guided by the Exploration and Preparation phases of the Exploration, Preparation, Implementation, and Sustainment (EPIS) framework, using focus group discussions and in-depth semi-structured interviews with inductive and deductive thematic analysis.

Peri-urban communities across the five administrative divisions of Lagos State, Nigeria.

128 stakeholders from 32 communities, including community, religious, market and youth leaders, primary healthcare staff, and household decision makers. Approximately half were female.

This was a pre-implementation needs assessment that included demonstrations of the clean stove and fuel.

Thematic domains describing barriers and enablers to adoption and implementation, mapped to EPIS inner, outer, and bridging factors.

Stakeholders reported barriers that included stove stacking, upfront stove cost, concerns about long-term fuel price and availability, equipment durability and maintenance, safety, mistrust of new technology, and uncertainty about stove performance for dishes requiring high heat and long cooking times. Reported facilitators included payment flexibility and subsidies, opportunities to test the stove, perceived benefits of cleaner and faster cooking with less soot, endorsement by community leaders, and interest in local retail and distribution to improve access.

Implementation planning for clean fuel and clean stove programmes should address affordability, reliable fuel supply chains, durability and service, culturally relevant cooking needs, and trust building through community leadership. These findings inform adaptation strategies for scale-up in similar low-resource settings.

NCT05048147.

Pre-exposure prophylaxis (PrEP) use among cisgender female sex workers (FSWs), a population at disproportionately high HIV acquisition risk in Uganda, remains suboptimal. Uptake and continued use are constrained by barriers, such as limited clinical hours, long distances to access facility-based PrEP services, and high mobility among FSWs. Community pharmacies may offer a more accessible PrEP delivery model due to extended operating hours and convenient locations. This study aims to evaluate the accessibility and capacity of pharmacies in Kampala, Uganda, to serve as potential sites for PrEP delivery.

We will conduct a concurrent mixed-methods study combining geospatial mapping, structured surveys, a discrete choice experiment (DCE), and in-depth interviews (IDIs). First, the study will compare the reach and accessibility of PrEP services through community pharmacies versus public healthcare facilities. To highlight PrEP service reach, we will use geospatial analysis to map pharmacies, PrEP clinics, FSW hotspots (i.e., areas where sex is exchanged), and HIV incidence. We will also calculate a PrEP facility needs ratio (number of PrEP facilities/HIV incidence) for each of Kampala’s administrative divisions and estimate travel distance and time to access PrEP services using cost–distance analysis. Perceived accessibility of PrEP services will be assessed through FSW surveys (n=50) and IDIs (n=20–30), guided by Levesque’s framework. Then, we will evaluate pharmacy capacity via surveys (n=274) and IDIs (n=20–30), exploring infrastructure, resources, and staff perspectives, informed by the Consolidated Framework for Implementation Research. Additionally, a DCE will be embedded in the pharmacy survey to elicit staff preferences for delivery approaches and analysed using mixed logit models. Finally, we will integrate quantitative and qualitative findings to provide a broad assessment of whether pharmacies are suitable venues for PrEP delivery to FSWs in Kampala. Enrolment will begin by April 2026 for FSWs and July 2026 for pharmacy staff.

Ethical approval has been obtained from the Infectious Diseases Institute Research Ethics Committee (IDI-REC-2025-175) and the Uganda National Council for Science and Technology (HS6178ES). Written informed consent will be obtained from all participants. We will disseminate study findings through stakeholder meetings, scientific conferences, and peer-reviewed publications.

Leprosy remains a significant public health challenge in many low and middle-income countries, including India. People affected by leprosy face multifaceted challenges: physical, psychological, social and economic. In response, donors support self-help groups (SHGs) to improve health, social integration and economic circumstances for marginalised people, including those with leprosy. This study aims to assess the sustainability of SHGs in India after the withdrawal of donor support by examining whether they remain functional and exploring the key factors, barriers and facilitators that influence their long-term social and economic viability.

To examine the functionality of SHGs after withdrawal of donor support, and to explore the factors, barriers and facilitators influencing their long-term social and economic sustainability.

Using qualitative methods, we conducted semistructured interviews with 40 key informants associated with five SHGs formed under the Self-Help Community Development Project implemented in an endemic state of India and funded by The Leprosy Mission Trust India.

It was an exploratory qualitative study using interviews with SHG members and key informants, situated within the self-help community-based project.

While some SHGs demonstrated resilience and adaptability, others faced challenges such as internal discord, loss of members to migration and lack of access to government schemes. Thematic analysis revealed key drivers and barriers to sustainability and realising the benefits of SHGs, highlighting variations in leadership, governance, economic performance and social engagement across groups.

SHGs are often sustained after the funding and managerial donor support have been withdrawn. The findings emphasise the importance of strong leadership, community support and external facilitation in sustaining SHGs and enhancing their impact on marginalised populations. This study contributes to understanding the role of SHGs in addressing the socioeconomic challenges faced by individuals affected by leprosy and offers insights for improving their long-term viability.

To examine the associations between food-related behaviours and nutrient intake on nutritional status among clients undergoing Community-Based Treatment and Rehabilitation (CBTaR) in Kelantan, Malaysia.

Cross-sectional analytical study.

Seven CBTaR centres (n=7) across the state of Kelantan, Malaysia.

A total of 393 adult clients (aged 18 years and above) enrolled in CBTaR programmes between June and December 2022 were selected through stratified random sampling.

The primary outcome was nutritional status, assessed using body mass index. Secondary outcomes included nutrient intake (macronutrients and micronutrients) and food-related behaviours (emotional eating, external eating, restrained eating and food addiction), measured through Bahasa Malaysia validated questionnaires and 24-hour dietary recalls. All variables were introduced into the structural equation modelling to examine the associations among these variables and their association with nutritional status.

The results revealed that food-related behaviour was significantly associated with the nutrient intake (β=–0.524, p≤0.001). Additionally, the drug use profile significantly determined the food-related behaviour (β=–0.129, p=0.006) and nutritional status (β=–0.134, p=0.007). Nutrient intake was found to be a significant predictor of nutritional status (β=–0.213, p≤0.001). Sociodemographic and drug use profiles were significantly correlated with nutritional outcomes through behavioural and dietary associations. Importance-performance map analysis identified nutrient intake as the most impactful variable, highlighting the need for urgent intervention (R²=0.272).

This study highlights that nutrient intake is a significant predictor associated with food-related behaviours on nutritional status among individuals with substance use disorder. Integrating nutrition counselling and behavioural interventions into CBTaR services may improve recovery and long-term health outcomes.

Accurate identification of adverse events after colonoscopy is essential for quality assurance in colorectal cancer (CRC) screening. Review of medical records is labour intensive as adverse events are infrequent. The object of this study was to investigate the accuracy of claims data in identifying adverse events after colonoscopy in CRC screening.

Cross-sectional, retrospective.

Males and females aged 50–74 years were randomised to once-only sigmoidoscopy or biennial faecal immunochemical test in a CRC screening trial at two screening centres in Norway. Participants in the present study underwent follow-up colonoscopy from 2012 to April 2020 after initial positive screening test. We reviewed medical records for adverse events within 30 days following 11 205 colonoscopies.

The primary outcome of the study was to assess the sensitivity of claims data from the Norwegian Patient Registry to identify lower gastrointestinal bleeding using emergency contact International Statistical Classification of Diseases and Related Health Problems 10th Revision diagnostic code sets under two definitions: a stringent definition (codes explicitly identifying bleeding) and a broad definition (including suggestive codes). Secondary outcome measures included the sensitivity to identify perforation using a stringent and a broad definition. Additionally, we assessed whether incorporating procedure codes and non-emergency contacts improved accuracy.

87 cases of lower gastrointestinal bleeding and eight perforations were confirmed. Sensitivity for bleeding differed between the centres (p

Use of claims data underestimated adverse event rates following colonoscopy. Difference in coding practice across hospitals underscores the need for standardised reporting in screening programmes.

NCT01538550.

Tourette syndrome is a common, disabling childhood-onset condition. Exposure and response prevention (ERP) is an effective treatment for tics, yet access remains limited due to a shortage of trained therapists and uneven geographical distribution of services. The ORBIT trial demonstrated that internet-delivered ERP is both clinically and cost-effective, but was developed on a university research platform, not suitable for widescale roll-out. To enable adoption by the National Health Service (NHS) in England, ORBIT has been redeveloped on an NHS compliant platform. This study will evaluate the usability, acceptability and preliminary outcomes of ORBIT on the new platform within an NHS tic disorder service.

This single-cohort usability study will recruit 20 children and young people (aged 9–17) with tics and their chosen supporters (parents/carers). Participants will receive a 10-week online ERP intervention supported by trained coaches. Outcomes include uptake, adherence, system usability, satisfaction and clinical measures such as the Yale Global Tic Severity Scale, Parent Tic Questionnaire and Goal-Based Outcomes. Qualitative feedback will be collected via semi-structured exit interviews. Usability metrics and adverse events will be monitored throughout.

The study has received ethical approval from North West Greater Manchester Research Ethics Committee (ref: 25/NW/0107). The findings from the study will inform future NHS adoption. The results will be submitted for publication in peer-reviewed journals.

In Indonesia, the second most natural disaster-prone country in the world, the tobacco industry exploits such crises via corporate social responsibility. The objective of this study was to map existing evidence on natural disasters and tobacco use in order to understand how tobacco control policies could be optimised in disaster-prone regions.

Scoping review.

ScienceDirect, PubMed and Google Scholar, with searches conducted twice: between January and April 2024 and again in August 2025.

All studies examining natural disasters, smoking behaviours and the tobacco industry.

Studies were assessed primarily on reports of tobacco use change, tobacco control policy enforcement, tobacco industry interference and mention of the role of stress. Data on country, disaster type, type of research study and sample details were also collated.

27 of the 611 identified studies were included in the final analysis. Two-thirds of studies reported an increase in smoking rates following disasters. No studies mentioned tobacco control policy enforcement or tobacco industry interference during disasters. Most of the studies (74%) which examined the relationship between disaster-related stress and smoking found a positive association. About half (51.9%) of the studies described disasters in the Americas.

Smoking rates often rise after stress-inducing disasters. More evidence is urgently required to assist countries like Indonesia in enforcing tobacco control and preventing tobacco industry interference.

While needs assessment is the starting point of good quality care, there is anecdotal evidence of patients receiving different care in similar circumstances. This study aims to investigate whether practice variation exists in needs assessments conducted by home care nurses and to identify the factors influencing these assessments.

A cross-sectional, quantitative retrospective study.

Primary care; home care nursing in the Netherlands in 2023.

Sampling was based on criterion sampling. Home care organisations were approached based on the following inclusion criteria: organisations providing home care nursing in the Netherlands, organisations from various regions of the country and organisations offering different types of home care nursing (eg, paediatric or palliative care), funded under the Dutch Health Insurance Act (Zvw). Organisations were excluded if they provided home care nursing funded by sources other than the Dutch Health Insurance Act. Home care nurses were recruited from participating organisations, each of whom had recently assessed the care needs of at least five patients. In total, 28 organisations and 258 home care nurses participated in this study, thereby yielding data from 1615 patients.

Assessed and delivered minutes of home care per patient per week.

Variation was primarily associated with patient-related factors. After accounting for these factors, 83% (assessed minutes) and 88% (delivered minutes) of the total variation was attributed to the patient level, 8% (assessed minutes) and 10% (delivered minutes) to the home care nurses’ level and 9% (assessed minutes) and 2% (delivered minutes) to the organisational level. Due to inadequate documentation in electronic health records, many missing values were identified.

The lack of nursing documentation suggests that missing factors may have contributed to variations in needs assessments. Thus, further research should comprehensively explore the patient-related factors currently absent from nursing documentation.

This scoping review aims to map evidence or literature on improvement strategies used by health leaders and professionals to strengthen the safety climate in the operating room.

A scoping review was performed on the basis of the method proposed by the Joanna Briggs Institute and applied to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews (PRISMA-ScR) extension.

16 academic and grey literature data sources were searched using search terms on 17 January 2025, namely, Medical Literature Analysis and Retrieval System Online via Pubmed, Latin American and Caribbean Literature on Health Sciences via the Virtual Health Library, Cumulative Index to Nursing and Allied Health Literature, Scopus, Web of Science, Embase, PsycINFO, Cochrane Library, WorldCat, Digital Library of Theses and Dissertations, Brazilian Association of Surgical Center Nurses, Center for Material and Sterilization and Anesthetic Recovery, Association of Portuguese Operating Room Nurses, Association of PeriOperative Registered Nurses, Institute for Healthcare Improvement, WHO and Agency for Healthcare Research and Quality.

Study selection, data extraction and synthesis were based on the following eligibility criteria based on the acronym PCC (participants, concept, context): participants (health leaders and professionals), concept (strategies to improve the safety climate) and context (operating room). This scoping review considered studies published from 2009 onwards.

Information on the objective, method and findings addressing improvement strategies employed to strengthen the safety climate in the surgical centre was retrieved. The findings are presented in tables and in a qualitative thematic summary.

A total of 26 studies were analysed, published between 2009 and 2024, with the USA as the country of origin of the publications with the highest number (11 studies). As for the methodological approach, intervention and quasi-experimental studies stand out. When the studies in this review were mapped, strategies that strengthened the safety climate in the operating room were identified and grouped into two main axes that are interrelated: communication tools and training programmes.

It is evident that the implementation of tools that promote communication and training programmes enhances safe surgical care, as they contribute substantially to the domains of the safety culture. The use of communication protocols in the operating room is recommended as a perioperative safety tool.

This scoping review adhered to a protocol previously published in this journal and that is registered on the Open Science Framework website (https://osf.io/zg8nu/).

To determine the time intervals between injury and orthopaedic admission, admission and surgery, and postsurgery length of stay and to elucidate factors contributing to delays in accessing orthopaedic services.

Prospective cohort study.

A tertiary hospital in the rural Eastern Cape province of South Africa.

413 adult patients admitted with femur fractures between January 2024 and July 2024.

The primary outcome was the time interval from injury to surgical fixation. Secondary outcomes included time from admission to surgery, length of hospital stay and reasons for delays.

Of 413 patients, only 22% (n=91) received surgical intervention within 48 hours of admission. The median time from injury to admission was 4 days (IQR 0–12), and injury to surgery was 13 days (IQR 0–713). Systemic factors, including limited theatre capacity and bed shortages, were the main reasons for delays. In the multivariate analysis, cardiac disease (adjusted OR, AOR=9.62), diabetes mellitus (AOR=4.36) and a Glasgow Coma Scale score of

Significant delays in femoral fracture fixation were observed, with fewer than 10% receiving surgery within 48 hours of injury. Addressing surgical capacity and referral pathways is essential to improving timely access to care.

Strengthening research capacity in Africa is vital for tackling pressing health, educational and socioeconomic challenges facing the continent. At the core of this effort is the cultivation of innovative research leaders through postgraduate training programmes that incorporate mentorship-infused supervision. Such models have demonstrated potential in improving research skills, boosting academic productivity and fostering leadership development among emerging scholars. This systematic review and meta-synthesis protocol aims to examine existing mentorship-infused supervision practices across African higher education institutions. The review seeks to identify effective models, uncover common challenges and barriers, and generate evidence-based recommendations to develop sustainable, contextually relevant strategies. Insights from this work will inform policies and practices to enhance postgraduate research training, advance research leadership and contribute to the broader goal of strengthening research ecosystems across Africa.

A systematic review and thematic meta-synthesis will be undertaken, focusing on qualitative research studies as well as the qualitative components of mixed-methods studies. Relevant studies published in English will be identified through a comprehensive search strategy. The electronic databases, including Medline/PubMed, Scopus, Web of Science, African Journals Online, EMBASE and CINAHL, will be searched to capture a wide range of peer-reviewed articles and grey literature. Databases will be searched from March 2026. Two reviewers will independently perform study selection, data extraction, quality assessment and evaluation of risk of bias, using the Critical Appraisal Skills Programme checklist.

This systematic review and meta-synthesis will analyse publicly available literature and does not require ethical approval, as it involves no primary data collection. It will adhere to established ethical and methodological standards, including proper citation and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The findings will be widely disseminated through open-access journal publication, conference presentations and targeted reports for universities, research institutions and policymakers to inform and support mentorship-based postgraduate research supervision across Africa.

Although timely surgery is essential for improving general health and psychosocial outcomes, delays in cleft surgery remain common in low- and middle-income countries, including Rwanda, where little is known about the underlying causes. This study aimed to explore the factors influencing delays in cleft surgery in Rwanda using the four-delay framework.

A phenomenological qualitative study was conducted between April and July 2024. We conducted 29 in-depth interviews with 15 caregivers of children with orofacial clefts and 14 healthcare providers involved in cleft care. Transcripts were analysed thematically using an inductive–deductive hybrid approach in MAXQDA (V.24), guided by the four-delay framework while allowing themes to emerge from the data.

This qualitative study was conducted across six Operation Smile-supported hospitals in Rwanda. Operation Smile is a non-governmental organisation providing cleft care in several low- and middle-income countries, including Rwanda. Among these facilities, one is a tertiary-level hospital located in Kigali city, while the others are secondary-level hospitals distributed across all provinces of the country.

Participants were purposively selected and comprised caregivers of children who underwent cleft surgery at Operation Smile-supported hospitals between 2023 and 2024, as well as healthcare providers with a minimum of 6 months’ experience delivering cleft care at these facilities.

Six major themes and 15 subthemes emerged. Limited caregiver awareness, cultural beliefs and inconsistent knowledge of clefts among healthcare providers influenced delays in seeking care. Reaching care was impeded by long distances, poor road infrastructure and inadequate transportation options. Receiving care was delayed by patient-related factors such as poor nutritional status of children and systemic issues, including shortages of specialised cleft care workforce (such as plastic surgeons, oral and maxillofacial surgeons, anaesthesiologists, etc) and surgical infrastructure. Remaining in care was affected by the absence of multidisciplinary follow-up services. Despite these barriers, caregivers appreciated the support services provided by Operation Smile, including nutrition, transportation and coverage of surgery costs.

Cleft surgery delays in Rwanda are driven by multifactorial barriers across all stages of care. Strengthening early identification, public awareness, health provider training and post-operative support systems is essential to reducing delays and improving outcomes. Findings support the need for integrated cleft care within national surgical plans and broader health system strengthening efforts, and encourage the social and psychological support to affected children and caregivers.

With growing interest in applying artificial intelligence (AI) to population breast cancer screening, the evidence base has expanded rapidly. This systematic review aims to systematically review and summarise the published evidence on the use of AI in breast cancer screening.

We conducted a systematic review of primary studies assessing AI for screening mammography, extracting test-accuracy metrics (sensitivity, specificity, recall and cancer detection rates) and workflow outcomes.

We searched the Cochrane Breast Cancer Group Specialised Register, Cochrane CENTRAL, PubMed, Embase (Elsevier), Scopus, ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform from January 2012 to June 2025; we also screened reference lists of included studies and relevant reviews. No language restrictions were applied.

Primary studies evaluating AI for screening mammography (digital mammography or digital breast tomosynthesis) in asymptomatic women, assessing AI as a standalone reader or AI-assisted radiologist workflows versus radiologists alone. Eligible designs included randomised trials, prospective paired reader studies, real-world implementation/registry cohorts, retrospective cohorts and multireader-multicase reader studies conducted in population-based or opportunistic screening settings. Key outcomes included diagnostic accuracy metrics (eg, sensitivity, specificity, Area Under the Curve (AUC) and/or programme metrics (cancer detection rate (CDR), recall/abnormal interpretation rate, positive predictive value, arbitration/workload). We excluded protocols, pilot/feasibility studies, case reports, editorials and studies without relevant accuracy or screening outcomes.

Two independent reviewers extracted data and assessed risk of bias. Study quality was appraised with Quality Assessment of Diagnostic Accuracy Studies-2 and an AI-specific critical appraisal tool, and findings were synthesised narratively with stratification by study design and AI integration role.

31 studies met the inclusion criteria, encompassing randomised controlled trials, prospective paired-reader studies, registry-based implementations and retrospective simulations, representing more than two million screening examinations across Europe, Asia, North America and Australia. When used as a second reader or within double-reading workflows, AI generally maintained or modestly increased sensitivity (up to +9 percentage points (PP)) while preserving or improving specificity. Triage and decision-referral configurations delivered the greatest operational benefit, reducing reading volumes by 40–90% while maintaining non-inferior cancer detection when thresholds were conservatively calibrated. Stand-alone AI achieved AUC values comparable to radiologists and similar cancer detection in real-world, non-enriched cohorts, although interval-cancer follow-up remains incomplete in several datasets. In prospective randomised evidence, including the Mammography Screening with Artificial Intelligence trial (MASAI) trial, AI-supported screening achieved higher CDRs (6.4 versus 5.0 per 1000; p=0.0021) with stable or reduced false-positive and recall rates. Across implementation and simulation settings, integration of AI reduced radiologist workload substantially, with triage and band-pass approaches reducing the number of reads by approximately 40–90%. Overall certainty is limited by heterogeneity across study designs, reliance on enriched datasets for some accuracy estimates and incomplete interval-cancer follow-up in several major studies.

Contemporary AI systems show diagnostic performance that is broadly comparable to radiologists and can substantially reduce reading workload, particularly when used as a second reader or triage tool. Emerging prospective evidence supports their safe integration in these roles, although transparent reporting, standardised evaluation and long-term population studies are still required before considering AI as a stand-alone reader. AI may improve workflow efficiency and possibly cancer detection, but definitive evidence on safety, especially interval cancer outcomes, remains essential.
