ObjectivesTo inform efforts to promote regular and normalized Bayesian reasoning, we studied factors associated with the degree to which surgeons use Bayesian reasoning to navigate uncertainty across different clinical scenarios.
MethodsScience of Variation Group members (153; 58% North America, 30% Europe, 69% over 15 years of experience) completed an online survey reading 8 scenarios of test and treatment decisions and chose one of 4 answer options with higher scores indicating more Bayesian reasoning. Internal consistency of the survey was assessed using Cronbach alpha.
ResultsThe average Bayesian reasoning score across all scenarios was 3.0 (IQR 2.7–3.2) on a 4-point scale, indicating a relative context-dependent variability. Completely non-Bayesian reasoning was selected least often (8.6%, 90 of 1,044) and fully Bayesian reasoning represented 29% (301 of 1,044) of responses. Most surgeons showed mixed patterns (defined as reasoning in which prior probability is acknowledged but underweighted, without explicit probabilistic updating): 85% (121 of 142) used fully Bayesian reasoning at least once (121 of 142) while 42% (60 of 142) used completely non-Bayesian reasoning at least once. The Cronbach alpha was 0.43 suggesting the scenarios measured different aspects of clinical reasoning rather a unified construct.
ConclusionsThe finding that surgeons use relatively context-dependent reasoning suggests an opportunity for surgeons to develop and practice Bayesian reasoning strategies both in training programs and in practice.
Although implementing evidence-based interventions has been shown to improve the quality of care, there is limited evidence evaluating how these interventions are implemented. In intensive care settings, the use of evidence-based protocols, guidelines and care bundles has been associated with enhanced care quality and reduced burden on patients.
To identify and map existing evidence on the evaluation of evidence-based intervention implementation in adults' intensive care.
A scoping review was conducted by including original published and unpublished studies in English and Finnish.
The studies were retrieved from five databases (CINAHL, Scopus, Ovid Medline, Medic ja Mednar) from January 2000 to December 2024. The data search was performed on 29 November 2022 and updated on 10 December 2024. The results were synthesized and presented in a tabular and descriptive form.
A total of 19 studies were included in the review. These studies evaluated the implementation of evidence-based interventions, focusing on nurse and patient outcomes. Nurse outcomes included measures such as compliance, knowledge and self-confidence. Patient outcomes included indicators such as body temperature, blood glucose, incidence of pressure ulcers and length of stay.
The evaluation of evidence-based intervention implementation does not consistently extend to the evaluation of the entire implementation process. More consistent research reporting would improve disseminating the evidence. The evaluation implementation makes it possible to show the impact of nurse and patient outcomes. The evaluation results can reveal the success of the implementation. Further research on evaluation implementation, development of systematic and comprehensive evaluation implementation methods, or evaluation matrix is needed.
The review will be useful for nursing professionals in planning evidence of implementation, developing or researching evaluation implementation. Promoting evaluation of evidence-based intervention implementation in Nursing can improve the quality of patient care, improve disseminating evidence and uniformities of care practice.
What Problem Did the Study Address? There is limited evidence of evaluation of evidence-based interventions of implementation. Evaluating evidence-based implementation is important to ensure the quality of patient care and patient safety.
What Were the Main Findings? Evaluation of implementation of evidence-based interventions focused on nurse and patient outcomes. Evaluation of the entire implementation process was not identified, and implementation strategies were not evaluated.
Where and on Whom Will the Research Have an Impact? Evidence-based practice implementation in nursing for researchers, developers, nursing leaders and clinical nursing practitioners who implement and evaluate evidence-based practice implementation.

No Patient of Public Contribution: This study did not include patient or public involvement in its design, conduct or reporting.
Randomised clinical trials (RCTs) are gold standard in evidence-based medicine, but follow-up typically relies on clinic visits and trial-specific data collection. Much of this information overlaps with routinely collected healthcare systems data (HSD), such as electronic health records and national registries. Leveraging HSD for trial follow-up has the potential to reduce cost, time and resource burden. However, concerns remain about data quality and evidence is needed to show that HSD-based outcomes are reported to an equivalent standard to trial-specific data.
The Blood Cancer Clinical Trials Long-term Follow-up Using Integrated Healthcare Systems platform will link data collected from multiple myeloma clinical trials with HSD to create a research database supporting extended follow-up and further methodological and clinical research.
This data-linkage study includes participants from multiple myeloma RCTs conducted by the University of Leeds between 2008 and 2021. NHS (National Health Service) England will link these participants to HSD, including deaths and cancer registrations, systemic anticancer therapy, radiotherapy and Hospital Episode Statistics.
We will compare trial-collected outcomes with those derived from HSD, including mortality, treatment, second cancer incidence and major adverse events. Long-term overall survival will be estimated using national mortality data. HSD-derived demographic and clinical variables will be used to assess population representativeness relative to the wider myeloma population. Time to next treatment will be derived and evaluated as a surrogate for progression-free survival. HSD-derived frailty measures will be examined for prognostic utility, and radiotherapy and hospital records will be analysed to characterise bone-related treatments and skeletal complications.
Ethical approval has been obtained from the East of England–Cambridge Central Research Ethics Committee, with Section251 support from the Health Research Authority on advice from the Confidentiality Advisory Group. Findings will be disseminated through publications, conference presentations and engagement with stakeholders and patient groups.
To identify and synthesise the ethical, feasibility and acceptability challenges associated with implementing eye-tracking research with clinicians in acute care settings and to explore strategies to address these concerns.
Scoping review using the Joanna Briggs Institute methodology.
Six databases (MEDLINE, CINAHL, EMBASE, Web of Science, APA PsycInfo and ProQuest Dissertations & Theses Global) were searched for peer-reviewed articles. Reference lists of included studies were also hand-searched.
Eligible studies involved clinicians using or interacting with eye-tracking devices in acute care environments and addressed at least one ethical, feasibility, or acceptability consideration. Data were extracted and thematically analysed. Knowledge users, including clinicians, ethicists and a patient partner, were engaged during protocol development and findings synthesis.
Twenty-five studies published from 2010 to 2024 were included. Seven challenges were identified: obtaining ethical approval, managing consent, privacy and confidentiality concerns, collecting data in unpredictable environments, interference with care, participant comfort and data loss or unreliability. Knowledge users highlighted the importance of early institutional engagement, clear protocols, continuous consent and context-sensitive ethical reflection.
Eye-tracking offers valuable insights into clinician behaviour and cognition, but its implementation in acute care raises complex ethical and methodological issues. Responsible use requires anticipatory planning, stakeholder engagement and flexible yet rigorous protocols.
By informing the development of ethically sound study protocols and consent practices, this work contributes to safer, more transparent and patient-centred research that respects participant autonomy and protects clinical workflows.
The protocol was registered with the Open Science Framework (https://osf.io/jn4yx).
Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA; Page et al., 2021) and its Extension for Scoping Reviews (Tricco et al., 2018).
A patient partner was involved in protocol development, interpretation of findings and development of study recommendations. Their contributions included participating in advisory groups and providing feedback alongside clinicians and ethicists during focus groups. This input helped ensure the research addressed patient-relevant priorities and informed the development of ethically responsible practices for conducting eye-tracking research in clinical care settings.

Biological effects induced by diverse types of ionizing radiation are known to show important variations. Nanodosimetry is suitable for studying the link between these variations and the patterns of radiation interactions within nanometer-scale volumes, using experimental techniques complemented by Monte Carlo track structure (MCTS) simulations. However, predicted nanodosimetric quantities differ among MCTS codes, primarily because each code employs distinct molecular-scale particle interaction models. This multi-code study examines these variations for low-energy electrons (20–10,000 eV), which play a critical role in energy deposition and biological effects by virtually all types of ionizing radiation. Specifically, the hypothesis tested in this work is that inter-code variability in nanodosimetry results is mainly caused by differences in assumptions regarding total interaction cross sections. Ionization cluster size distributions and derived nanodosimetric parameters were simulated with seven MCTS codes (PARTRAC, PHITS-TS, MCwater, PTra, and three Geant4-DNA options) in liquid water as a surrogate for biological tissue. Significant inter-code differences were observed, especially at the lowest energies. They were substantially reduced upon replacing the original cross sections in each code with a common, averaged dataset, created ad-hoc for this study and not based on theoretical assumptions. For example, for 50 eV electrons in 8 nm spheres, the variability in the predicted mean ionization numbers decreased from 23% to 5%, and in the probability of inducing two or more ionizations from 34% to 7% (relative standard deviations). This quantification demonstrates that total interaction cross sections are the primary source of uncertainty at low electron energies. A sensitivity test using DNA damage simulations with the PARTRAC code revealed that cross section variations notably affect biological outcome predictions. Replacing the code’s original cross sections with the averaged ones increased the predicted double-strand break yield by up to 15%. These findings underscore the urgent need for improved characterization of low-energy electron interaction cross sections to reduce uncertainties in MCTS simulations and enhance mechanistic understanding of radiation-induced biological effects.To develop prediction models for short-term outcomes following a first acute myocardial infarction (AMI) event (index) or for past AMI events (prevalent) in a national primary care cohort.
Retrospective cohort study using logistic regression models to estimate 1-year and 5-year risks of all-cause mortality and composite cardiovascular outcomes.
Primary care practices in England contributing data to the Clinical Practice Research Datalink (CPRD) Aurum and CPRD GOLD databases between 2006 and 2019.
Patients with an incident (index) or prevalent AMI event. Models were trained on a random 80% sample of CPRD Aurum (n=1018 practices), internally validated on the remaining 20% (n=255) and externally validated using CPRD GOLD (n=248).
Discrimination assessed using sensitivity, specificity and area under the receiver operating characteristic curve (AUC). Calibration assessed using calibration plots.
In the index (prevalent) cohorts, 94 241 (64 789) patients were included in the training and internal validation sets, and 16 832 (7479) in the external validation set. For the index cohort, AUCs for 1-year [5-year] all-cause mortality were 0.802 (95% CI 0.793 to 0.812) [0.847 (0.841 to 0.853)] internally and 0.800 (0.790 to 0.810) [0.841 (0.835 to 0.847)] externally. For the primary composite outcome (stroke, heart failure and all-cause death), AUCs were 0.763 (0.756 to 0.771) [0.824 (0.818 to 0.830)] internally and 0.748 (0.739 to 0.756) [0.808 (0.801 to 0.815)] externally. Discrimination was higher in the prevalent cohort, particularly for 1-year mortality (AUC: 0.896, 95% CI 0.887 to 0.904). Models excluding treatment variables showed slightly lower but comparable performance. Calibration was acceptable across models.
These models can support clinicians in identifying patients at increased risk of short-term adverse outcomes following AMI, whether newly diagnosed or with a prior history. This can inform monitoring strategies and secondary prevention and guide patient counselling on modifiable risk factors.
To examine the association between maternal and neonatal biochemical variables in babies born to mothers with hypertensive disorders of pregnancy (HDP) and admitted to the neonatal unit within 24 hours of delivery.
Retrospective chart review study.
Specialised antenatal hypertension clinic and neonatal unit in a tertiary unit referral hospital.
Pregnancies complicated with HDP (N=282) and their neonates if admitted to the neonatal unit within 24 hours of delivery.
We examined the association between maternal and neonatal biochemical variables, after controlling for maternal, neonatal and pregnancy characteristics.
There were strong associations and independent prediction of neonatal levels by maternal levels for urea, creatinine, sodium and calcium. The highest associations were between neonatal and maternal urea and creatinine, where the only predictor was the respective maternal variable (model R2= 0.61 and 0.60, respectively). Similarly, maternal sodium and calcium were the strongest predictors for neonatal sodium and calcium (model R2= 0.36 and 0.22, respectively). On the contrary, the strongest predictor for neonatal total protein, albumin and globulin was the gestational age (model R2= 0.43, 0.35 and 0.48, respectively) with no maternal contribution for total protein and albumin.
Maternal levels of urea, creatinine, sodium and calcium, in a pregnancy complicated by HDP, should be taken into consideration by both the obstetric and neonatal teams when deciding on timing of delivery and providing intensive monitoring.
It has been reported that pregnant women used more cosmetics daily than non-pregnant women. Phenoxyacetic acid is the main metabolite of phenoxyethanol, the most frequent preservative in cosmetics used in Europe, previously associated with reproductive effects (longer time to conception, endocrine disruptors in newborns and poorer verbal comprehension in children). In France, specialised platforms (PREVention ENvIronment Reproduction (PREVENIR)) in university hospital maternity wards are dedicated to evaluating environmental and occupational exposures in patients with pregnancy-related pathologies and supporting targeted prevention efforts. These platforms are composed of occupational health physicians, obstetrician-gynaecologists, midwives, occupational health nurses, and occupational health and environmental engineers. To assess the efficacy of these platforms, we developed a randomised clinical trial, the protocol for which is presented in this paper. The primary objective of the PREVENIR-G Study is to compare the change in urinary phenoxyacetic acid concentrations from baseline to 3 months postintervention between an intervention group and a control group. To date, the intervention has been integrated into routine care in certain facilities; however, its efficacy remains unproven. It is therefore essential to assess the relevance of this intervention, considering both its potential benefits and any adverse effects, such as increased stress or anxiety.
This study is an unblinded, randomised clinical superiority trial with two parallel groups (intervention vs no intervention) in four university maternity hospitals in France. We will include 300 pregnant women (aged 18 years or older) who are under 24 weeks of gestation (150 per group) referred to the participating PREVENIR platforms for management. The intervention will consist of clinical prevention management through the PREVENIR platforms, involving a consultation with an environmental health expert for an assessment of environmental and occupational exposures. During the consultation, targeted prevention messages will be provided based on identified exposures. The no intervention comparator will be a waiting-list control group. At the inclusion visit, patients will receive urine collection vials for samples to be collected at baseline and again at 3 months. Urine samples will be collected twice in a single day, on three separate days, during the collection week at home. In the week following the urine collection period, only participants in the intervention group will engage with the PREVENIR platforms. The primary outcome will be the difference in the urinary phenoxyacetic acid concentration between baseline and 3 months postintervention, compared between the intervention and control groups.
The study has been approved by the hospital ethics committee (CCP Ouest 2, no. 2023-A00941-44). All participants will provide written informed consent. Results will be shared through presentations and publications.
This paper outlines key developments, innovations, and milestones in the field of spirituality and spiritual care in nursing.
A discursive paper.
Nursing scholars have significantly influenced the profession and contributed to the development of nursing knowledge, particularly in the field of spirituality and spiritual care. Key research has focused on nurses' perceptions and attitudes toward spirituality, clarifying foundational spiritual concepts, and establishing a framework of core spiritual care competencies for the profession.
Despite these advancements, significant gaps remain in nurses' knowledge, understanding, and experience in providing spiritual care. The development of agreed-upon spiritual care competencies at the European level offers important guidance for the profession, and educational initiatives are underway to support their integration. However, the field remains in an early stage of development, and further research is needed to embed spiritual care competencies into national and international nursing policy and practice. Moreover, continued research is also essential to inform and evaluate current educational programmes and nursing interventions, and to support the translation of evidence-based knowledge into effective spiritual care delivery.
Spiritual support is proven to be an important consideration for many patients and families globally. Imbedding spiritual care education into both undergraduate and postgraduate nursing curricula is essential to prepare nurses to address the spiritual needs of patients in healthcare settings. Structured curricula that provide clear instructions on how to recognise, assess, and respond to spiritual concerns in clinical practice can enhance nurses' competence and confidence. Embedding spiritual care into education and training helps normalise spiritual care as a component of holistic nursing, supporting its inclusion in everyday care rather than treating it as an optional or marginal practice. Such educational integration has the potential to improve the consistency and quality of spiritual care across healthcare settings.
Internationally there are evident gaps in the consistent provision of spiritual care to patients and their families. These are being addressed through conceptual clarity, the agreed-upon competencies, and enhanced educational initiatives. It is essential to continue to increase awareness among the nursing profession on the necessity of addressing spiritual care needs, within the context of cultural perspectives to ensure that value is placed on the significance of these issues on a global scale.

This study explored perceptions of older adults racialised as Black on structural resilience across the life course.
A qualitative descriptive study.
Using purposive sampling, we recruited 15 Black adults aged 50 and older residing in Baltimore, Maryland, including individuals possessing historical or current knowledge of the community. Semi-structured interviews were conducted to elicit participants' experiences with structural resources during childhood, adulthood and late adulthood. Interviews were audio-recorded, transcribed verbatim and analysed using content analysis.
Of the 15 participants, three identified as male (20.0%) and 12 as female (80.0%), with an average age of 70.9 ± 8.2 years. The analysis identified nine categories of structural resilience, confirming its multifaceted and dynamic nature. Common categories present across all life stages included: Built environment, civic engagement, food and housing, healthcare, and social capital and cohesion. Life stage–specific categories included child and family services, educational supports, and workforce development supports during childhood and adulthood, and financial support during adulthood and late adulthood.
These categories were interdependent and spanned across life stages, illustrating the dynamic, cumulative and relational qualities of structural resilience. Furthermore, structural resources were identified as key to safeguarding, empowering and restorative responses to adversity.
These findings contribute to the development of a nuanced, life course–informed framework of structural resilience and highlight the need for ecological strategies that address structural forces shaping health and well-being, particularly among older adults racialised as Black.

Patients in intensive care units (ICUs) frequently require mechanical ventilation, with approximately half needing invasive ventilation through an orotracheal tube. For these patients, gastric tube (GT) insertion is routinely performed to administer nutrition and medications or to drain gastric contents. The insertion route (oral or nasal) may affect the incidence of ventilator-associated pneumonia (VAP), a significant ICU care complication. This study aims to compare the impact of oral versus nasal GT insertion on the incidence of VAP in intubated ICU patients.
The SONG trial (NCT 05915663) is a multicentre, open-label, two-period, two-intervention, cluster randomised crossover superiority trial. 16 French ICUs will participate. ICUs will be randomised to periods of nasogastric or orogastric tube placement. The trial includes a practice standardisation period, followed by two 12-month inclusion periods separated by a monitoring and washout period. The primary endpoint is the incidence rate of VAP at day 28, confirmed by three independent physicians. Secondary endpoints include the ease of GT insertion, measured by the number of attempts.
This study received approval from a central ethical review board on 12 April 2024 (CPP Sud-est VI, registration number 23.00943.000175). Patients are included after informed consent or, when not possible, from next of kin. If none are available, the investigator will proceed with emergency inclusion, following French law. When consent is initially obtained from the next of kin or through emergency inclusion, the investigator will seek consent from the patient as soon as possible. Data will be anonymised and patient confidentiality maintained. Results will be published in peer-reviewed journals and presented at scientific meetings.
