Achieving high-quality primary healthcare (PHC) remains essential to improving health systems performance and advancing progress towards attainment of universal health coverage, particularly in sub-Saharan Africa (SSA), where gaps in service delivery persist. Capacity-building interventions, such as mentorship, in-service training and supportive supervision, have been widely employed to improve the quality of PHC delivery. The evidence base is, however, fragmented across diverse settings, intervention types and outcome measures. This systematic review will examine the evidence on how capacity-building interventions improve the quality of PHC services in SSA, with a focus on the domains of effectiveness, safety, people-centredness, timeliness, equity, integration and efficiency as propounded by the WHO.
We will conduct a systematic review using established evidence synthesis methods and report the findings in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines. Eligible studies will include peer-reviewed and grey literature published in English between 2000 and 2025, focusing on capacity-building interventions aimed at improving PHC quality in SSA. We will search databases including PubMed, Embase, Web of Science, Scopus, Google Scholar and the African Journals Online. Study selection will follow the Population (PHC providers), Exposure (capacity-building interventions) and Outcome (quality of PHC delivery across WHO domains) framework. Quality assessment will use the Mixed Methods Appraisal Tool (MMAT). Data will be narratively synthesised using Atlas.ti software.
Ethical approval is not required because there will be no collection of primary data. Only published studies/records available on peer-reviewed literature and grey sources will be included. Findings will be disseminated through a peer-reviewed journal, academic conferences and stakeholder platforms in SSA.
The protocol has been registered in PROSPERO (CRD420251131534) and reported according to PRISMA-P guidelines.
The aim of this study was to assess the level of continuum of maternal, newborn, childand reproductive health coverage using the composite coverage index (CCI) and to identify its determinants, including socioeconomic, community context, individual and family, and health service-related factors, among postpartum women one year after childbirth in Ethiopia.
This study was a secondary analysis of longitudinal data from the second cohort of the performance monitoring for action (PMA) Ethiopia survey, which was conducted from 2021 to 2023. Data were collected at four intervals: a baseline survey, a 6 week postpartum survey, a 6 month postpartum survey and a 1 year postpartum survey to track reproductive, maternal, newborn, and child health indicators.
The study was conducted from the major regions of Ethiopia, namely Amhara, Oromia, Southern Nations, Nationalities and Peoples’ and the city administration of Addis Ababa.
A total of 2297 women enrolled in cohort two of PMA Ethiopia. Of these, 2072 completed the 6 week, 1874 the 6 month and 1858 (along with their 1800 children) the 1 year postpartum follow-up surveys. The final analysis was based on a weighted sample of 1793 participants.
The outcome variable for this study was the continuum of maternal, newborn, child and reproductive health services, assessed using the CCI. We applied quantile regression analyses at the 10th, 25th, 50th, 75th and 90th quantiles of the outcome variable. Statistical significance of predictors was determined based on p values
The findings revealed that the mean CCI was 56.2% (95 % CI 52.5% to 59.8%), indicating the proportion of maternal, newborn, child, and reproductive health services received. Notably, only 4% of women received all 12 maternal, newborn, child, and reproductive health services as part of the continuum of care, while 1.1% did not receive any intervention. The study identified several factors significantly associated with CCI across different quantile levels, including maternal age, maternal education level, household wealth index, first antenatal care visit (ANC1), parity, previous facility delivery, partner encouragement, use of maternity waiting homes, and administrative regions.
Based on the findings of this study, the coverage of continuum of maternal, newborn, child and reproductive health services in Ethiopia remains low. This highlights a substantial gap in Ethiopia’s progress toward the 2030 sustainable development goal target. Ethiopia must significantly accelerate efforts to improve maternal, newborn, child and reproductive health services in order to achieve the set goals. Policymakers and programme implementers should carefully consider the identified determinants when designing policies and programmes aimed at enhancing maternal, newborn, child and reproductive health outcomes.
Administration of antibiotics before incising the skin (‘surgical antimicrobial prophylaxis’) is a critical infection prevention strategy in surgery. Extending doses of prophylaxis into the postoperative period is a common practice in cardiac surgery; however, the benefit has not been clearly established and may lead to emergence of antimicrobial resistance and patient harm. We present the protocol for a large international multicentre, adaptive, pragmatic, double-blind, three-arm, placebo-controlled, randomised, non-inferiority clinical trial to compare the incidence of surgical site infection after three different durations of postoperative surgical antimicrobial prophylaxis in patients undergoing cardiac surgery.
This adaptive, multi-arm multistage non-inferiority trial will compare intraoperative only (Arm A), to intraoperative and 24 hours (Arm B) and, to intraoperative and 48 hours (Arm C) of intravenous cefazolin and placebo as surgical antimicrobial prophylaxis in 9180 patients undergoing cardiac surgery. The adaptive design allows for potential dropping of any of the three arms if clear inferiority is indicated at any of the scheduled interim analyses. The trial will evaluate the clinical and cost-effectiveness of the three different antibiotic prophylaxis durations.
Ethics approval will be obtained at all participating sites. Results of the study will be submitted for publication in peer-reviewed journals and the key findings presented at national and international conferences. Patients and members of the public will also be involved in the dissemination and translation of the trial results.
To describe healthcare professionals’ (HCPs) assessment of safety culture in adults and paediatric critical care units in governmental hospitals in Kuwait.
A cross-sectional survey study.
Adults and paediatric critical care units in Kuwait from January to April 2023.
Full-time HCPs (physicians, nurses and clinical pharmacists) who are in direct contact with patients and work in adults and paediatric critical care units.
Patient safety culture practices.
The population consisted of 945 HCPs from adult and paediatric critical care units. In general, across most dimensions, perceptions were more positive toward the patient safety culture. Adult critical care settings were mostly higher in negative responses compared with the paediatric setting. In general, all the HCPs responded positively towards ‘Teamwork Climate’, ranging from 41.5% to 85.0%, with the same pattern in the adult and paediatric settings. In both settings, ‘Safety Climate’ in general was responded to positively, ranging from 51.3% to 86.2%, and patterns between the two settings were the same. ‘Job Satisfaction’ showed positive responses between 68.2% and 88.3%.
In this study, HCPs from adult and paediatric critical care units rated patient safety culture dimensions positively. The patient safety procedures needing improvement were staff shortages, harsh workloads, poor communication and training. Providing frequent communication training and supporting personnel could further strengthen the critical care safety culture.
Adolescent tobacco use (ATU) is a global public health concern, causing significant morbidity and premature death. This study aimed to assess trends in the prevalence of ATU in Indonesia between 2009 and 2019 and to identify factors contributing to the observed changes.
This study performed secondary data analysis of three consecutive waves (2009, 2014, and 2019) of the Indonesian Global Youth Tobacco Survey (IGYTS). Weighted prevalence estimates and complex survey data analysed using multivariate logistic regression were established across the three-wave surveys. A pooled IGYTS data set was explored to determine the risk factors of the ATU. A multivariate decomposition analysis (MDA) was used to determine factors contributing to the prevalence change in male adolescents over the last two surveys.
The prevalence of ATUs was 21.1% (38.2% in males; 6.4% in females), 18.6% (32.7% in males; 3.9% in females) and 19.8% (36.8% in males; 3.5% in females) for the three consecutive surveys, respectively. Being older adolescents, male, exposed to SHS (secondhand smoke) at home, tobacco industry promotion, not knowledgeable of the dangers of tobacco smoke and SHS, and against banning smoking in public places were associated with ATU consistently across the surveys. In addition, inadequate anti-cigarette media and not being knowledgeable of the difficulty of quitting smoking were also identified as risk factors in the pooled data. MDA showed that 88.94% of the explained change was due to differences in the composition of explanatory variables between the last two surveys.
This study suggests that social influence and tobacco industry promotion significantly impact ATU in Indonesia. Governments should emphasise these factors in their tobacco control interventions.
To describe the structured process of threshold optimisation for a commercially available multiclass chest X-ray (CXR) deep learning model, to evaluate its diagnostic performance across different operating thresholds, and to estimate its potential operational impact within an artificial intelligence (AI)-enabled triage workflow in a primary care setting.
Retrospective diagnostic performance evaluation with threshold-based analysis.
Primary care radiography services in Singapore, using data derived from two primary care clinics and a tertiary hospital.
A total of 816 adult frontal chest radiographs were included (multiethnic Asian, 464 males, 352 females; mean age 60.8 years). Images were selected to represent the spectrum of findings often encountered in primary care. Exclusion criteria included paediatric studies, lateral or oblique radiographs, and findings not supported by the AI model (eg, bony abnormalities and medical devices).
Primary outcome measures were sensitivity, specificity, and negative and positive predictive value (NPV and PPV). Secondary outcomes included estimated potential operational improvement, which is calculated by dividing the number of true negatives by the total number of CXRs.
At the default threshold of 0.15, the AI model achieved a sensitivity of 87.3% (95% CI 83.9% to 90.4%) and an NPV of 87.0% (95% CI 83.6% to 90.2%). Lowering the threshold to 0.10 increased sensitivity to 93.2% (95% CI 90.7% to 95.5%) and NPV to 91.3% (95% CI 88.2% to 94.3%), with specificity of 71.7% (95% CI 67.3% to 76.1%). These trade-offs were considered acceptable for a safety-focused co-triage workflow prioritising minimisation of false negatives.
Threshold optimisation is critical for adapting AI models to context-specific clinical workflows. Our study shows that adjusting the operating threshold enabled prioritisation of sensitivity and NPV, supporting safe AI-assisted triage in primary care. This is a deeply collaborative process that must involve radiology and clinical teams: selecting appropriate thresholds aligned with clinical objectives for safe and effective implementation. Future work will assess real-world operational impact and user acceptance following prospective deployment.
In the constantly advancing, dynamic and competitive fields of residency programmes, continuous professional development is crucial for fostering competent and well-rounded health professionals. Multisource (MS) (360°) feedback is widely adopted internationally as a comprehensive tool to assess residents’ performance, yet it is not commonly practised in the Kingdom of Saudi Arabia (KSA). Therefore, this study aims to explore awareness and readiness among residents in KSA to receive 360° feedback.
A qualitative exploratory study using in-depth semistructured interviews.
Secondary and tertiary care hospitals in major cities, recognised for postgraduate training by the Saudi Commission for Health Specialties of KSA.
For the study, medical residents of diverse specialties were recruited by the convenience sampling method. Informed written consent for participation was taken. Audio recorded interviews data were transcribed, and a thematic analysis technique was used to extract the themes.
A total of 7 female and 2 male residents participated. The study extracted four major themes with 31 subthemes accordingly. The subthemes were categorised under the following major themes: lack of awareness of the concept, acknowledging the value of multisource feedback (MSF), receptivity/readiness and challenges.
The study underscores the significant potential of MS (360°) feedback in fostering the personal and professional development of medical residents in KSA. The participants initially lacked a clear understanding of MSF, including its goals, key stakeholders and the competencies it assesses. However, many residents swiftly acknowledged its benefits in offering holistic and equitable evaluation. They demonstrated a strong desire for its implementation across all residency programmes to foster their personal and professional development.
In recent decades, transcranial electrical stimulation (tES) has become a widely used non-invasive method for modulating brain function in clinical and non-clinical populations. However, existing tES trials exhibit substantial methodological heterogeneity, often limiting the reproducibility and interpretability of findings. There currently exists a paucity of consensus-driven, standardised recommendations outlining the key factors that should be reported and/or controlled in tES studies. Accordingly, this project aims to develop Consolidated Guidelines for Reporting and Evaluation of studies using tES (CoRE-tES), a tool designed to assess the methodological quality and reporting of laboratory-based and home-based tES studies. These guidelines will support improved quality, consistency, replication and transparency in research involving tES modalities, including transcranial direct current stimulation, transcranial alternating current stimulation and transcranial random noise stimulation.
CoRE-tES will be developed and disseminated over five stages. Stage 1 will comprise a review of recent tES literature to assess methodological and reporting quality. Stage 2 will employ a Delphi process to seek agreement among international tES experts on a list of items for inclusion in CoRE-tES. In stage 3, a consensus meeting will be held to synthesise and prioritise the agreed items to form CoRE-tES. Stage 4 will involve production of the final CoRE-tES checklist and an accompanying evaluation and elaboration document. In stage 5, CoRE-tES will be disseminated via journal publication, conferences, professional meetings and social media campaigns.
Ethics approval has been obtained from the Western Sydney University Human Research Ethics Committee (approval number H16803). Findings will be disseminated through scientific conferences and peer-reviewed journal publications, and CoRE-tES will be indexed on the Enhancing the QUAlity and Transparency Of health Research Network website.
This study aims to determine the incidence and impact of ocular injuries among the different combat sports disciplines of boxing, mixed martial arts (MMA), kickboxing and Muay Thai in Texas, USA.
A case–control study was conducted to analyse retrospective postmatch physical reports from combat sports matches that took place in the state of Texas from January 2019 to January 2022. Ocular injuries and other match characteristics such as sport type and match outcome were identified by postmatch physical reports. Postmatch physical reports were collected from the Texas Department of Licensing and Regulation database. Statistical analysis was used to stratify injuries and compare the impact of injuries on match outcome.
Combat sports fighters in Texas, USA.
3070 participants were included in the study. Participants were fighters who participated in combat sports matches in Texas, USA, between January 2019 and January 2022.
The original plan was to measure the incidence of ocular injuries across different combat sports including boxing, MMA, kickboxing and Muay Thai. However, due to a limited sample size of kickboxing and Muay Thai matches, the ocular injury incidence was only measured for boxing and MMA. The association between ocular injury and match outcome was assessed using 2 statistical analysis.
The respective incidence rates of ocular injuries in boxing and MMA were 9.7 and 12.2 injuries per 100 matches. The association between ocular injury and match outcome (win, lose or draw) was statistically significant in boxing but not statistically significant in MMA matches.
Our findings revealed that ocular injuries are significantly associated to losing a boxing match (p=0.011), but not associated to match outcome in MMA (p=0.232). Additionally, MMA matches report a larger variety of ocular injuries compared with boxing matches.
The prevalence of cardiovascular diseases (CVDs) is rapidly increasing across Asia, with the burden particularly high among individuals aged ≥50 years. Elevated low-density lipoprotein cholesterol (LDL-C) level is a well-established causal risk factor for CVDs. Mediterranean-Dietary Approaches to Stop Hypertension Intervention for Neurodegenerative Delay (MIND) diet is a cardioprotective diet, which is rich in plant-based foods. Combining it with stress-reducing practices, including forest bathing (FB), which involves immersive exposure to forest environments, has been shown to reduce LDL-C levels and other cardiovascular risk factors by modulating pro-inflammatory responses. However, existing evidence is limited due to small sample sizes and poor study design. Therefore, this study aims to investigate whether the MIND diet combined with FB can reduce CVD risks among Chinese adults in Hong Kong. It also compares the effects of the MIND diet combined with FB on cardiovascular and mental health.
A single-blind, randomised controlled trial involving three groups will be used to assess the impact of the MIND diet combined with FB on LDL-C levels in adults aged 50–75 years with elevated LDL-C levels. Participants (n=273) from local community centres will be randomly assigned to the MIND-plus-FB (who will receive nutrition education, follow the MIND diet for 12 weeks and participate in regular FB sessions), MIND-alone (who will receive nutrition education and follow the MIND diet for 12 weeks) or routine care (who will continue their usual activities and receive a general health talk along with pamphlets on cardiovascular risks) group. The change in LDL-C levels will be measured at weeks 4 and 12 (primary outcome). Additionally, changes in high-density lipoprotein cholesterol level, triglyceride level, glucose level, systolic blood pressure, waist circumference, body mass index, anxiety levels and emotional state will also be assessed at weeks 4 and 12. Statistical analyses will include intent-to-treat, 2 test, analysis of variance and generalised estimating equations.
This study has been approved by the Research Ethics Committee of Tung Wah College, Hong Kong (reference number: REC2023164). Research findings will be disseminated through publication in peer-reviewed journals and presentations at academic and primary healthcare conferences.

Cardiovascular (CV) disease is the leading cause of morbidity and mortality globally. Low-density lipoprotein cholesterol (LDL-C) is an important modifiable risk factor of major adverse cardiovascular events. Patients without prior myocardial infarction (MI) or stroke but with established risk factors and elevated LDL-C may benefit from intensive lipid-lowering therapy (LLT); however, the size and potential healthcare burden of this population globally are not known. The benefits of evolocumab, a proprotein convertase subtilisin/kexin type 9 inhibitor, in these patients, are currently being studied in the phase 3 Effect of Evolocumab in Patients at High Cardiovascular Risk Without Prior Myocardial Infarction or Stroke (VESALIUS-CV) trial. To characterise the high-risk pre–CV-event (VESALIUS-CV–like) individuals in the real world, an observational study is being conducted across multiple countries.
This retrospective cohort study will use a common protocol and an analytical common data model approach to characterise VESALIUS-CV–like individuals in the real world across different geographical regions and healthcare settings. The study period will be from 2010 to 2022, subject to data availability in study sites. Patients aged 50 years and older at high risk of CV disease but without prior MI or stroke will be included in this study. VESALIUS-CV–like individuals are defined through a combination of the following: (1) one diagnosis of coronary artery disease, cerebrovascular disease, peripheral artery disease or diabetes with microvascular complications or chronic insulin use; (2) an elevated LDL-C measurement and (3) other high-risk factors. The objectives of this study are to estimate the prevalence of VESALIUS-CV–like individuals, describe their characteristics and care pathways and estimate their incidence rates of CV events and healthcare costs. The prevalence of VESALIUS-CV–like individuals will be expressed as annual prevalence; patient characteristics at index date will be presented using summary statistics; care pathways will be summarised as LLT prescription across time; and the incidence of defined CV events will be expressed as events per person-years as well as at certain time periods. Healthcare costs will be presented as CV-related costs in different time periods.
Approvals of the study protocol were obtained from relevant local ethics and regulatory frameworks for each participating database. The results of the study will be submitted to peer-reviewed scientific publications and presented at scientific conferences.
