International guidelines on breast cancer (BC) screening have differing recommendations leading to uncertainty on best practices for primary care providers. The purpose of this study was to create a Canadian best practices document on BC health and screening for primary healthcare providers through multidisciplinary consensus using Nominal Group Technique and Delphi method.

A 9-member multidisciplinary expert group and a patient advocate participated in the consensus methods and voting. Experts included those involved in BC management and two primary care physicians. Twenty-nine experts across BC disciplines participated in external review.

Two study objectives included (1) building consensus on key ‘best practice’ behaviours related to BC-related health and screening and (2) building consensus on specific definitions related to BC screening.

The final consensus document consists of 65 statements grouped in five categories with companion resources to support uptake of all best practices. Categories include identification and work-up for diagnostic imaging, risk factors and identifying individuals eligible for high-risk screening, shared decision-making, decisions and referrals for BC screening and screening outcomes. Special areas of focus were shared decision-making, age to initiate screening, and BC screening in special populations.

We created a comprehensive consensus document distilling the latest evidence to provide practical Canadian consensus-based advice on specific ‘best practice behaviours’ related to BC health and screening to serve as a resource for providers.

Musculoskeletal pain is a global issue affecting millions of individuals. Healthcare provider gender bias (HCP-GB) in pain management or treatment may have implications. This study aimed to systematically (1) identify and map the scientific and grey literature as it relates to HCP-GB in the assessment, diagnosis and management of musculoskeletal pain, and (2) identify current gaps that necessitate further research.

This scoping review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR).

The following databases were searched: PubMed (National Library of Medicine), Embase (Elsevier), Scopus (Elsevier), CINAHL Complete (Ovid), Academic Search Complete (EBSCOhost), Pre-Prints Database (National Library of Medicine) and Rehabilitation Reference Center from inception to August 2022 and updated in May 2025. Relevant grey literature was identified.

All screening was performed by two reviewers during title/abstract screening and full-text screening stages. Articles published in English, Spanish and German were included if they involved participants with musculoskeletal pain and examined HCP-GB as the dependent variable.

Two reviewers independently extracted data from the bibliometric, study characteristics and pain science variables. Results were descriptively mapped, and the frequency of concepts, population and characteristics was narratively reported.

21 full-text articles were included. All articles were published in North America and Europe. A total of 3694 healthcare providers from various specialty areas were examined. A majority of studies (57.1%; n=12) measured HCP-GB using written case vignettes, 33.3% (n=7) used case vignettes plus virtual human pictures/videos, and 9.5% (n=2) used real patients. The influence of patients’ sex in HCP pain assessment was reported in 28.5% (n=6) of the articles, while 42.9% (n=9) reported gender bias regarding HCP non-pharmacological treatment recommendations. Male patients were more likely to receive exercise recommendations for back pain and laboratory testing, whereas female patients received more psychological treatment recommendations and counselling from their HCP.

While there appears to be inconsistent use of the terms sex and gender, the literature informing this review suggests an existence of gender bias in the management of patients with musculoskeletal pain. Future research should be more purposeful in the use of sex/gender-related terms and consider exploring the impact of implicit bias training to rectify potential gender biases present in HCP.

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.

Metabolic dysfunction-associated steatotic liver disease (MASLD) and gestational diabetes mellitus (GDM) are prevalent metabolic disorders in pregnancy, posing significant risks to maternal and fetal health. This study evaluates the effectiveness of metformin, in combination with lifestyle modifications, compared with lifestyle modifications alone, in reducing the incidence of diabetes, pro-inflammatory liver markers, adverse maternal and neonatal outcomes and total gestational weight gain in pregnant women diagnosed with MASLD in the first trimester.

This parallel-arm, randomised controlled trial will recruit pregnant women (≤14 weeks of gestation) with confirmed MASLD from antenatal clinics of tertiary care public hospitals in Puducherry, India. Participants will be consecutively enrolled until a sample size of 296 is reached. Block randomisation will ensure balanced group allocation, with allocation concealment maintained using sequentially numbered opaque sealed envelopes. The intervention group will receive oral metformin (500 mg two times per day) alongside structured lifestyle modification counselling, while the control group will receive lifestyle modification counselling alone. Primary outcomes include GDM incidence, changes in pro-inflammatory markers, MASLD grading (assessed via liver function tests and ultrasound) and adverse maternal outcomes such as hypertensive disorders, polyhydramnios, genitourinary infections, caesarean delivery and postpartum haemorrhage. Neonatal outcomes assessed include macrosomia, stillbirth, intrauterine death, birth injury, shoulder dystocia, respiratory distress and neonatal hypoglycaemia. The secondary outcome is total gestational weight gain. Participants will be followed at 24–28 weeks, 34–36 weeks and post partum (within 6 weeks of delivery). Data collection will be conducted using a pretested structured questionnaire, with data entry and management performed using REDCap software. Statistical analysis will be conducted using STATA V.4, applying both intention-to-treat and per-protocol analyses. Effect sizes will be reported as proportions and relative risks with 95% CIs, ensuring robust statistical inference.

This study provides a rigorous framework to assess metformin’s role in managing MASLD and preventing GDM, thereby promoting favourable maternal and neonatal outcomes. Findings will contribute to improved clinical management, public health strategies and policy recommendations.

The study was approved by the JIPMER Institutional Ethics Committee (JIP/AEC/2023/01/011), and the findings will be disseminated through peer-reviewed journals and academic conferences.

This study aimed to assess the associations between childhood adverse socioeconomic conditions and intrinsic capacity in older adults using an integrative approach to ageing.

A cross-sectional study.

We used data from the Lausanne Cohort 65+, a population-based longitudinal study that has been conducted in Lausanne, Switzerland, since 2004.

Lausanne citizens aged 67–71 years old.

Intrinsic capacity was assessed in 2015 using validated self-reported measures and performance tests. Partial Least Squares Structural Equation Modelling was used in a formative approach to calculate the global score of intrinsic capacity and the scores of its domains. Adverse socioeconomic conditions in childhood were retrospectively assessed in 2014 using self-reported measures of financial strain, dietary restrictions and child labour.

The study sample included 1328 individuals. Multivariable regressions revealed that the global score of intrinsic capacity was lower in individuals who reported financial strain (B=–0.15, p=0.029) and dietary restrictions (B=–0.314, p=0.004) in childhood. They further showed an association between financial strain and lower locomotor and sensory capacities (B=–0.173, p=0.011 and B=–0.153, p=0.027, respectively), and between child labour and a lower score on cognition (B=–0.342, p

Our results emphasise the critical role of early life conditions in healthy ageing. They highlight the importance of financial support for families and access to nutrition.

To explore the views and perspectives of British South Asian (BSA) women and Positive Health Programme (PHP) facilitators on the usefulness and experiences of the PHP intervention for managing postnatal depression (PND) in primary care settings.

Qualitative study with semi-structured interviews to explore perceptions of acceptability and implementation. A patient and public involvement group provided their insights and feedback on study topic guides, analysis and outcomes.

We sampled trial participants from the PHP intervention database to ensure variation in geographic setting, age, socioeconomic status and ethnicity. PHP facilitators involved in the trial were also invited to participate in an interview.

Interviews with study participants were conducted at participants’ homes, and community centres, or via phone. Interviews with PHP facilitators were conducted via phone or online. Interview recordings were transcribed verbatim and analysed using thematic analysis and subsequently the Theoretical Framework of Acceptability (TFA) was applied. Recruitment took place between February 2017 and March 2020.

Thirty interviews were conducted—19 trial participants and 11 PHP facilitators. The PHP intervention was viewed positively, with appreciation of its therapeutic content and components such as childcare and refreshments that facilitated engagement. Participants reported improved confidence and well-being and supported their needs. Participants understood the intervention’s purpose. Both intervention participants and facilitators noted strengthened self-efficacy.

Some participants experienced difficulties balancing childcare and attendance, implying a need for logistical assistance. Stigma about mental health in the BSA community was viewed as persistent, recommending future programmes efforts on strategies to reduce stigma and develop supportive environment.

This study demonstrates the possibility of PHP intervention being integrated into routine care by providing culturally tailored support for BSA women with PND, primarily through family engagement and facilitator support. Future research on scalability, alongside community engagement efforts, will strengthen its acceptability and broader applicability.

There is limited evidence regarding the outcomes and impacts of Patient and public involvement (PPI) in research, mainly based on narrative studies. Existing frameworks for supporting and evaluating PPI often require adaptation to specific contexts, and comprehensive instruments are needed. From an international perspective, strengthening the scientific foundation that underpins PPI is crucial to generate stronger evidence to understand which approaches work best, in which contexts, and with what effects.

To promote PPI implementation in German health research, this project aims to (1) Establish an evaluation framework, (2) Develop a modular evaluation tool in the form of a questionnaire and (3) Pilot and psychometrically validate the tool.

A three-phase mixed methods approach will be employed, integrating qualitative and quantitative data. First, we will explore with researchers, research partners and other stakeholders in health services research what contributes to meaningful and successful PPI through a web-based survey and focus groups. Findings are discussed in a codesign workshop in which participants agree on an evaluation framework based on a LOGIC model. Second, items from international instruments that evaluate PPI are deductively assigned to the evaluation framework. Further items are developed based on the focus groups from phase 1. Cognitive pretests and qualitative review will be conducted with researchers and patients in order to refine the item pool and develop the evaluation tool. Third, the evaluation tool with modules for researchers and patients will be piloted in a web-based survey. Data analysis will include thematic analysis for qualitative data and descriptive and psychometric analyses for quantitative data. A participatory research team will provide ongoing support throughout all project phases.

Ethical approval has been obtained from the Local Ethics Committee of the Centre for Psychosocial Medicine, University Medical Centre Hamburg-Eppendorf (LPEK-0889). The study will follow the principles of the Helsinki Declaration and good scientific practice. Results will be disseminated at national and international conferences, public symposiums and in peer-reviewed journals, contributing to the internationally developing field of PPI in research and addressing relevant research gaps.

Global migration has steadily risen, with 16% of the UK population born abroad. Migrants (defined here as foreign-born individuals) face unique health risks, including potential higher rates and delays in diagnosis of infectious and non-communicable diseases, compounded by significant barriers to healthcare. UK Public Health guidelines recommend screening at-risk migrants, but primary care often faces significant challenges in achieving this, exacerbating health disparities. The Health Catch-UP! tool was developed as a novel digital, multidisease screening and catch-up vaccination solution to support primary care to identify at-risk adult migrants and offer individualised care. The tool has been shown to be acceptable and feasible and to increase migrant health screening in previous studies, but to facilitate use in routine care requires the development of an implementation package. This protocol describes the development and optimisation of an implementation package for Health Catch-UP! following the person-based approach (PBA), a participatory intervention development methodology, and evaluates our use of this methodological approach for migrant participants.

Through engagement with both migrants and primary healthcare professionals (approximately 80–100 participants) via participatory workshops, focus groups and think-aloud interviews, the study aims to cocreate a comprehensive Health Catch-UP! implementation package. This package will encompass healthcare professional support materials, patient resources and potential Health Catch-UP! care pathways (delivery models), developed through iterative refinement based on user feedback and behavioural theory. The study will involve three linked phases (1) planning: formation of an academic–community coalition and cocreation of guiding principles, logic model and intervention planning table, (2) intervention development: focus groups and participatory workshops to coproduce prototype implementation materials and (3) intervention optimisation: think-aloud interviews to iteratively refine the final implementation package. An embedded mixed-methods evaluation of how we used the PBA will allow shared learning from the use of this methodology within the migrant health context.

Ethics approval granted by the St George’s University Research Ethics Committee (REC reference: 2024.0191). A community celebration event will be held to recognise contributions and to demonstrate impact.

To assess the impact of gender, age, ethnicity and country of primary medical qualification (CoQ) on outcomes in the 2024 UK ST3 surgical national selection process.

Retrospective cross-sectional analysis of national recruitment data.

UK-wide ST3 surgical training recruitment.

2009 unique ST3 applicants to six surgical specialties (otolaryngology, plastic surgery, urology, paediatric surgery, trauma and orthopaedics and general surgery); neurosurgery, cardiothoracic surgery and oral and maxillofacial surgery were excluded.

Offer of a ST3 National Training Number (NTN).

CoQ was the strongest factor associated with success. International medical graduates had lower odds of receiving offers in all specialties, notably in general surgery (adjusted OR (aOR)=0.21, 95% CI 0.14 to 0.33, p

ST3 selection outcomes are primarily associated with CoQ. UK-trained applicants have a consistent advantage. Women remain less likely to be offered an NTN than men in Trauma and Orthopaedics. This analysis enables detailed and timely equity monitoring across surgical specialties and flags areas for intervention.

Electronic health register's (eRegisters) use have recently gained popularity in Africa. eRegisters are used to capture real-time patient information on several encounters with a healthcare provider. Given poor maternal and child health outcomes in Lesotho, eRegisters provide a promising innovative means of enhancing health outcomes, especially those related to midwifery. eRegisters capture maternal and newborn care services provided at healthcare facilities. Such data are important for informing evidence-based midwifery practice. Lesotho, a landlocked, sub-Saharan African country, piloted use of an eRegister in 2018. However, factors promoting eRegister and data use have not been fully documented. Therefore, this study explored factors promoting eRegister and data use for midwifery practice in Lesotho.

The study used a descriptive qualitative approach with interviews and focus group discussions used to collect data. Descriptive content analysis as outlined by Erlingsson and Brysiewicz (2017) was followed during data analysis.

The study was conducted at three of the eRegister piloting facilities in Lesotho to examine eRegister implementation across different levels of care. Data collection occurred between December 2023 and March 2024.

Purposive sampling was used to recruit healthcare workers across the three facilities. Participants were selected to capture the range of relevant roles and experience with eRegister across each facility, and 7, 6 and 5 participants were recruited.

Five categories emerged as factors promoting eRegister and data use: system readiness, organisational environment, data value and utility in practice, human resource competency and digital literacy and governance and stakeholder engagement.

This study identified critical factors that promote the use of the eRegister and data in Lesotho. The findings suggest that while external funding and partner responsiveness have been pivotal in sustaining eRegister operations, long-term sustainability will require stronger national ownership, including domestic investment in infrastructure, technical support and digital health governance. Future studies should explore the effect of eRegister use on clinical outcomes and examine strategies for scaling up digital health interventions in resource-limited settings.

As of 2024, 123.2 million people had been forcibly displaced as a result of persecution, armed conflict or climate-related catastrophes, and these numbers are predicted to rise. There is a growing awareness of possible intergenerational effects of trauma on life-course health and well-being, however few studies have followed individuals longitudinally starting prenatally. This paper describes the first large prenatal birth cohort study in a refugee context in a lower middle-income country. This study aims to investigate the potential lifespan health and developmental implications of being born into a protracted humanitarian context, and what factors can buffer from the adversity posed by conflict and displacement.

We outline our approach of recruiting, consenting and gathering data from pregnant Rohingya refugee and host community women (N=2888; 80% Rohingya) over the course of 12 months in Cox’s Bazar, Bangladesh.

A fifth wave of data collection, when children were 6 months old, was completed in April 2025. Rohingya women were substantially less literate; were marrying and having children at slightly younger ages, were more likely to live in crowded, resource-limited households and exhibited higher rates of clinically significant post-traumatic stress disorder and anxiety than host community women.

There is a critical need for research in displaced populations in order to elucidate potentially lasting transgenerational impacts of experiencing conflict and displacement trauma, and the prenatal and postnatal factors that support health and development across the life span. The next follow-up is planned when the children turn 36 months of age (starting March 2026).

To describe the association between place of residence in Alberta, Canada, and cardiovascular event risk among adults newly treated with metformin for type 2 diabetes.

Retrospective cohort study.

Administrative data from Alberta, Canada between 2008 and 2023.

Adult new metformin users, categorised by residence (rural, urban, metropolitan) from postal codes 1 year before metformin.

Cause-specific hazard models were constructed for the primary composite outcome (cardiovascular mortality, hospitalisation for an acute coronary syndrome or stroke) and each of the secondary outcomes (components of the primary outcome and all-cause mortality). Models were adjusted for baseline demographics, healthcare utilisation and diabetes complications.

A total of 236 005 adult new metformin users were identified and distributed across the rural-urban continuum (66% metropolitan, 10% urban, 24% rural). Mean age was 55 years, 55% were men, and mean follow-up time was 5.7 years. There were 19 059 primary composite outcome events, and rural residents were more likely to experience the outcome, adjusted HR (aHR): 1.09 (95% CI 1.06 to 1.13), compared with metropolitan. A significant interaction between residence and cardiovascular event history was identified. When stratified, risk of the primary outcome among those without cardiovascular history and living in a rural area was aHR: 1.16 (95% CI 1.11 to 1.20). Among rural residents with cardiovascular history, the risk was aHR: 0.84 (95% CI 0.78 to 0.91).

Quantifying the association between residence and risk of cardiovascular events may focus the allocation of healthcare resources. Development of targeted intervention programmes should focus on primary prevention in rural areas and secondary prevention in metropolitan areas.

Hysterectomy, a common surgical procedure, is frequently associated with moderate-to-severe postoperative pain and a high incidence of postoperative nausea and vomiting (PONV). Dexamethasone, a corticosteroid, may help alleviate these symptoms; however, existing evidence is largely drawn from mixed surgical populations and does not specifically address its efficacy and safety in hysterectomy patients. This meta-analysis provides a focused and updated synthesis of randomised controlled trials (RCTs) in this population, incorporating time-stratified pain outcomes and subgroup analyses by dose, surgical approach, timing and route of administration to evaluate the role of dexamethasone in postoperative recovery.

Systematic review and meta-analysis using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach.

PubMed, Scopus, Google Scholar and The Cochrane Central Register of Controlled Trials (CENTRAL) were searched through 1 November 2024.

We included RCTs comparing dexamethasone with placebo for postoperative outcomes in hysterectomy patients.

Two independent reviewers used standardised methods to search, screen and code included studies. Risk of bias was assessed using the Cochrane Collaboration and Evidence Project tools. Meta-analysis was conducted using random effects models. Findings were summarised in GRADE evidence profiles and synthesised qualitatively.

15 RCTs (1362 patients) were included. Dexamethasone significantly reduced PONV (risk ratio (RR): 0.53, 95% CI 0.47 to 0.61, p2: 0% high certainty) and pain scores at 24 hours (mean difference (MD): –0.20, 95% CI –0.35 to –0.05, p=0.009, I²=0%, moderate certainty), 8–12 hours (MD: –0.60, 95% CI –0.88 to –0.31, p2: 27%, moderate certainty and 4 hours (MD: –0.43, 95% CI –1.07 to 0.21, p=0.19, 93%, moderate certainty). It also decreased the use of rescue antiemetics (RR: 0.57, 95% CI 0.43 to 0.75, I²: 39%, high certainty) and postoperative opioid consumption (standardised MD: –0.48, 95% CI –0.90 to –0.05, p=0.03, I²: 74%, low certainty). The effects of rescue analgesics and hospital stay duration were nonsignificant. Subgroup analyses showed consistent antiemetic efficacy of dexamethasone across doses, timings, routes and procedures. For pain, greater analgesic effects were seen with higher doses and perineural administration, particularly at 8–12 hours. The risk of bias was low in most studies, but evidence of publication bias was observed for the pain score outcome.

Dexamethasone is an effective adjunct in hysterectomy, significantly reducing PONV and postoperative pain at 8–12 and 24 hours, particularly with 4–10 mg doses. Benefits are consistent across routes, timings and surgical approaches, with greater early analgesia after perineural use. It reduces opioid consumption but has a limited effect on rescue analgesia, supporting its role as a complementary analgesic. While generally considered safe, current safety data are limited, highlighting the need for further research. These results support its use in multimodal recovery protocols and identify priorities for future studies in high-risk and diverse surgical populations.

This study explored how Structured Medication Reviews (SMRs) are being undertaken and the challenges to their successful implementation and sustainability.

A cross-sectional mixed methods online survey.

Primary care in England.

120 clinical pharmacists with experience in conducting SMRs in primary care.

Survey responses were received from clinical pharmacists working in 15 different regions. The majority were independent prescribers (62%, n=74), and most were employed by Primary Care Networks (65%, n=78), delivering SMRs for one or more general practices. 61% (n=73) had completed, or were currently enrolled in, the approved training pathway. Patient selection was largely driven by the primary care contract specification: care home residents, patients with polypharmacy, patients on medicines commonly associated with medication errors, patients with severe frailty and/or patients using potentially addictive pain management medication. Only 26% (n=36) of respondents reported providing patients with information in advance. The majority of SMRs were undertaken remotely by telephone and were 21–30 min in length. Much variation was reported in approaches to conducting SMRs, with SMRs in care homes being deemed the most challenging due to additional complexities involved. Challenges included not having sufficient time to prepare adequately, address complex polypharmacy and complete follow-up work generated by SMRs, issues relating to organisational support, competing national priorities and lack of ‘buy-in’ from some patients and General Practitioners.

These results offer insights into the role being played by the clinical pharmacy workforce in a new country-wide initiative to improve the quality and safety of care for patients taking multiple medicines. Better patient preparation and trust, alongside continuing professional development, more support and oversight for clinical pharmacists conducting SMRs, could lead to more efficient medication reviews. However, a formal evaluation of the potential of SMRs to optimise safe medicines use for patients in England is now warranted.

To explore the challenges experienced by people with intellectual disability, their carers and health and social care professionals when using and managing medication.

A synthesis of qualitative research using meta-ethnography.

We searched seven databases: MEDLINE, Embase, CINAHL, Science, Social Science and Conference Proceedings Citation Indices (Web of Science), Cochrane Library, PsycINFO and Proquest Dissertations and Theses from inception to September 2022 (updated in July 2023).

We included studies exploring the challenges and perceptions of people with intellectual disability, their carers and health and social care professionals regarding medication management and use.

We reviewed 7593 abstracts and 475 full texts, resulting in 45 included papers. Four major themes were identified: (1) Medication-related issues, (2) navigating autonomy and relationships, (3) knowledge and training needs and (4) inequalities in the healthcare system. We formulated a conceptual framework centred around people with intellectual disability and described the interconnectedness between them, their carers and health and social care professionals in the process of managing and using medication. We identified challenges that could be associated with the person, the medication and/or the context, along with a lack of understanding of these challenges and a lack of capability or resources to tackle them. We developed an overarching concept of ‘collective collaboration’ as a potential solution to prevent or mitigate problems related to medication use in people with intellectual disability.

The effective management of medication for people with intellectual disability requires a collaborative and holistic approach. By fostering person-centred care and shared decision-making, providing educational and practical support, and nurturing strong relationships between all partners involved to form a collective collaboration surrounding people with intellectual disability, improved medication adherence and optimised therapeutic outcomes can be achieved.

Children with limited access to dental care can be negatively impacted by reduced frequency of oral health monitoring, delays in diagnosis of dental disease and increased waits for dental care, resulting in them experiencing more disease (extent and amount). Smartphone-based intraoral photography has been cited as having the potential to improve oral health monitoring for children through screening; however, it has not been well evaluated, and its limitations are unclear. The picture-perfect study aims to assess diagnostic accuracy, feasibility and acceptability to determine whether remote photographic monitoring can be effectively integrated into pathways of dental care for children aged 6-16 years.

Observational, cross-sectional, mixed-methods study with three workflows: Workflow 1: development of user-friendly, comprehensive guidance to help parent/carers (parents) take high-quality intraoral photographs of their children’s mouths. The guidance will be codesigned with parents and healthcare professionals. Workflow 2: diagnostic accuracy using intraoral photographs taken by a parent of their children will be evaluated by comparing clinicians' diagnoses from the photographs to gold-standard clinical visual-tactile examinations. Parent–child dyads (n=110) will be recruited to capture intraoral photographs using positioning aids, guidance and smartphones provided by the research team. The diagnoses will focus on plaque accumulation, gingival health, restoration status and dental caries. Diagnostic accuracy will be assessed using sensitivity, specificity, positive predictive value, negative predictive value and area under the curve. Workflow 3: assessment of feasibility and acceptability will be through task completion rates, photograph quality and participant feedback. Qualitative interviews and an online survey will capture parents’ and children’s experiences. Observational data will provide insights into practical challenges.

This study, approved by the National Health Service (NHS) Research Ethics Committee (Integrated Research Application System [IRAS]: 24/EE0137), will be conducted in adherence to the Declaration of Helsinki and Good Clinical Practice (GCP) guidelines. Written informed consent will be obtained from all participating parents, with age-appropriate assent from children prior to enrolment. Participants have the right to withdraw at any time without explanation, and their data will be anonymised to ensure privacy and confidentiality. Study findings will be disseminated through peer-reviewed journals, conference presentations and reports to relevant stakeholders.

The study protocol has been registered on the Open Science Framework: https://doi.org/10.17605/OSF.IO/WX29D.
