Background Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and post-COVID condition are complex, debilitating illnesses characterized by persistent fatigue and post-exertional malaise. Recovery is uncommon without targeted intervention; however, emerging clinical reports suggest that a subset of patients experience full resolution of symptoms after engaging in mind-body approaches. Patient perspectives on these interventions are divided, and qualitative evidence exploring successful recovery pathways is rare. This protocol outlines a study to investigate the contextual factors and patient-constructed explanations surrounding full recovery from ME/CFS or post-COVID condition using mind-body approaches. Methods and analysis We will employ a qualitative descriptive design rooted in a constructivist paradigm. Purposive and snowball sampling will be used to recruit approximately 20 adults from established infection-associated fatigue networks who self-report full recovery (lasting three months or more) from ME/CFS or post-COVID condition following a mind-body approach. Data will be collected through semi-structured interviews conducted via Zoom, and investigator reflexivity will be reported. Demographic information, including comorbidities, will be documented to contextualize the sample. Data will be analyzed inductively using reflexive thematic analysis. To ensure research rigor and reporting transparency, the study will adhere to the 15-point checklist of criteria for good thematic analysis proposed by Braun and Clarke. Dissemination We will publish our findings in a peer-reviewed, open-access journal and present at relevant academic conferences. A lay summary of the results will also be shared directly with participating patient recovery networks.

Background: Qualitative research provides insights into human behavior, perspectives, and lived experience. While existing standards like the Consolidated Criteria for Reporting Qualitative Research (COREQ) have improved transparency and rigor, the integration of large language models (LLMs) into qualitative research introduces new challenges for not covered by current guidelines. LLMs transform analytic processes and blur the line between human interpretation and algorithmic text generation, raising concerns about transparency, authorship, and epistemic trust. The here presented COREQ+LLM guideline extends COREQ to establish comprehensive reporting standards for LLM use in qualitative research. Methods: The study followed the EQUATOR Network's guideline development framework in two phases: (1) a systematic scoping review to identify best practices for reporting LLM use in qualitative research, and (2) a Delphi consensus process with international experts in qualitative research, AI, medicine, ethics, and journal editing to develop a comprehensive reporting checklist. Findings: The scoping review identified 149 studies relevant for full-text review. From this literature, 29 preliminary reporting items were extracted. In the first Delphi round, international experts (N=141) assessed the items' relevance. 20 items were accepted for inclusion in the guideline (>75% agreement); however, four required reevaluation in the second round, five underwent wording revisions, and six new items were proposed. In the second Delphi round (N=115; retention rate 82%), one was excluded, while four items still lacked consensus. Remaining items were discussed in a virtual consensus conference with nine representatives of the expert panel, resulting in the inclusion of two and the exclusion of two others. The final checklist comprises 31 items grouped into seven categories, serving as an extension of the original COREQ checklist. Interpretation: COREQ+LLM offers structured, consensus-based guidance to enhance transparency, reproducibility, and methodological rigor in qualitative research using LLMs. Its adoption will support researchers, reviewers, and editors in maintaining trust and scientific integrity.

IntroductionFalls are a major cause of injury-related morbidity, mortality, and healthcare utilisation among older adults, with the greatest burden occurring in those aged [≥]80 years. Multicomponent exercise programmes that include balance and resistance exercises reduce falls, whereas the effect of resistance training delivered as a standalone fall-prevention intervention remains uncertain. Existing resistance-training trials have generally been small, underpowered for fall outcomes, and have produced inconsistent findings, despite reduced muscle strength being an important modifiable risk factor in the oldest old. The resistance training prescription used in these studies has not always aligned with recommendations for optimal strength adaptations in terms of intensity or progressive overload, which may explain this uncertain efficacy. Therefore, this study aims to determine whether 12 months of high-intensity progressive resistance training reduces fall rates in community-dwelling adults aged [≥]80 years with reduced muscle strength. Methods and analysisThis single-centre, randomised controlled trial conducted in Trondheim, Norway, includes 241 community-dwelling adults aged [≥]80 years with reduced muscle strength. Participants are randomly assigned (1:1) to either standard care with written physical activity guidance or a twice-weekly high-intensity progressive resistance training intervention for 12 months. The primary outcome is the rate of falls over 12 months. Secondary outcomes include time to first fall, fall-related injuries, muscular function, physical performance, balance, body composition, cardiometabolic health, cognition, and participant-reported outcomes. Cost-effectiveness is assessed from a healthcare perspective over the 12-month intervention period using costs and quality-adjusted life years. Analyses follow the intention-to-treat principle, using negative binomial regression for the primary outcome. The first participant was included on 30 March 2023, and the last participant was included on 29 September 2025. The 12-month intervention period is expected to be completed by September 2026. Ethics and disseminationThe study has received approval from the Regional Committee for Medical and Health Research Ethics in Norway (REK; reference number 462261). All participants provided written informed consent before participating. Findings will be shared via peer-reviewed publications, conference presentations, and communication with stakeholders and the public.

Abstract Objectives To conduct a Delphi process to inform an international, consensus definition of manuscript peer review. Design Three-round Delphi consensus study including two surveys and one virtual consensus meeting. Peer review features identified through a prior scoping review were rated on a 5-point Likert scale in Rounds 1 and 2 and voted on using include, exclude, and abstain options in Round 3. Consensus was defined as [≥]80% agreement. Setting International experts representing interest holders affected by manuscript peer review across the fields of biomedical, health, and social sciences, economics, and healthcare-related industries. Participants Round 1 participants were purposively recruited via email from corresponding authors of articles included in the preceding scoping review. Round 2 participants were those who completed Round 1. Round 3 participants were purposely selected to address gaps in representation from earlier rounds, with attention to diversity of perspectives and equity-relevant characteristics informed by PROGRESS-Plus (e.g., geographic location, gender, race/ethnicity, occupation, and socioeconomic context). Participants were required to communicate in English. Main outcome measures Consensus on the terminology, scope, characteristics, functions, processes, and reviewer characteristics that should inform a definition of manuscript peer review. Results Across the three rounds (N=143, 109, and 16 participants, respectively), 44 peer review features across six domains (Characteristics, Function, Motivation, Assessment, Process, and Challenges) and six peer reviewer characteristics met the consensus threshold for inclusion. Consensus was also reached on terminology to describe manuscript peer review and the peer review workflow. Results were synthesized into a final conceptualization of manuscript peer review, consisting of one definition and eight pillars.The consensus definition is: Manuscript peer review is a structured process by which human reviewers assess scholarly manuscripts, with the aim of improving the quality and trustworthiness of published research in line with norms of reciprocity to the research community. The eight pillars characterize manuscript peer review and are as follows: Principled, Constructive, Timely, Transparent, Professional, Quality, Confidential, and Pluralistic. Conclusions This three-round international Delphi established a consensus-based, normative conceptualization of manuscript peer review as a distinct, human-led process to improve the quality and trustworthiness of scholarly research. The resulting definition and eight pillars may provide a shared foundation for research, evaluation, education, and improvement across publishing contexts while allowing operational features to remain adaptable.

Purpose: Rapid Assessment of Avoidable Blindness (RAAB) surveys are widely used to estimate the prevalence and causes of blindness and vision impairment among adults aged 50 years and older. We examined how far estimates of eye-care need depend on whether presenting or pinhole acuity, and unilateral or bilateral impairment, is used. Methods: We analysed 12 RAAB surveys undertaken between 2018 and 2023 in India, Nepal, Pakistan, Kenya, Tanzania and Uganda. Three person-level measures were compared: presenting visual acuity (PVA) in at least one eye, PVA in the better-seeing eye, and pinhole acuity in the better-seeing eye. Estimates were adjusted for the two-stage cluster design and age-standardised to the WHO world standard population. Results: Of 48,185 participants examined (response rate 94.3%), vision impairment based on pinhole acuity in the better eye (9-19%) was substantially lower than on PVA in the better eye (18-37%) or in at least one eye (33-51%). Increasing age (adjusted odds ratio [AOR] per year 1.106; 95% confidence interval [CI] 1.103-1.109), female sex (AOR 1.13; CI 1.08-1.19) and South Asian survey location (AOR 3.04; CI 2.78-3.33) were independently associated with impairment. Age-standardisation widened the difference between survey locations (prevalence ratio 1.50 crude, 1.66 standardised). Conclusions: Substantial vision impairment persists in the surveyed districts of both regions. The large gap between presenting and pinhole acuity indicates a considerable addressable burden, and restricting estimates to bilateral impairment in the better-seeing eye omits a further substantial share of need. The higher prevalence in the South Asian locations most plausibly reflects survey site selection and uncorrected refractive error rather than a regional epidemiological difference.

Introduction: Clinical deterioration in patients admitted to hospital wards is a major cause of preventable morbidity and mortality and is frequently preceded by abnormalities in vital signs that occur hours before serious adverse events occur. Early identification of patients at risk provides an opportunity for timely intervention before irreversible organ dysfunction develops. The objective of this trial is to evaluate whether implementing a wireless patient monitoring system reduces mortality and cardiopulmonary failure in patients admitted to hospital wards. Methods and analysis: The i-PROTECT trial is designed as a stepped-wedge cluster randomized controlled trial. Hospital wards (total of 28 wards, constituting clusters in this design) are randomized to have wireless monitoring for selected high-risk patients, 7 wards at a time, with every 7 wards constituting a sequence. In the first period, all wards will have no wireless monitoring. After a baseline period of 2 (+1 transition) months, the intervention is implemented in a randomly selected new sequence every 3-month period until the intervention is implemented in all sequences. The control group will receive usual care with standard intermittent monitoring and no wireless monitoring. The calculated sample size is 13160 patients. The primary endpoint is cardiopulmonary failure; a composite endpoint of 30-day in-hospital mortality, cardiac arrest, and need for vasopressor or intubation. The trial started on Feb 1, 2026, and is expected to complete patient follow-up by the end of May 2027. Ethics and dissemination: The trial was approved by the Institutional review board (IRB) of Ministry of National Guard Health Affairs (IRB/2623/23). The results will be presented at relevant national and international critical care conferences and published in international peer-reviewed journals.

Background Adverse childhood experiences are major determinants of mental disorders, health-risk behaviours and non-communicable diseases across the life course, but evidence from India remains limited. This study aims to estimate the prevalence and patterns of adverse childhood experiences among Indian adolescents, examine their associations with mental health and non-communicable disease risk factors, and evaluate a culturally adapted school-based intervention integrating trauma-informed care and social-emotional learning. Methods A sequential mixed-methods study will be conducted among approximately 1,632 adolescents in 16 public and private schools in Chandigarh and Mohali, India. Phase I is a cross-sectional survey of adverse childhood experiences, mental health, perceived stress, sleep, screen time and behavioural and biological risk factors for non-communicable diseases. Phase II comprises focus group discussions and key informant interviews with students, parents, teachers, counsellors and mental health professionals to inform intervention development. In Phase III, findings from both phases will guide development of the intervention using the ADDIE (Analysis, Design, Development, Implementation and Evaluation) instructional design framework. In Phase IV, adolescents reporting ACE exposure will participate in a school-based intervention delivered over 8-12 weeks by trained psychologists, comprising trauma-informed social-emotional learning sessions, individual counselling sessions for high-risk adolescents (at least six sessions), school-wide awareness activities and parental sensitization. Effectiveness will be evaluated using a quasi-experimental pre-post design. The primary outcome will be change in emotional and behavioural difficulties measured by the Strengths and Difficulties Questionnaire (SDQ). Secondary outcomes will include changes in depressive symptoms (Patient Health Questionnaire-9), perceived stress, sleep quality, school functioning, and behavioural risk factors for NCDs. Recruitment began in April 2026 and is ongoing; data collection is expected to be complete by June 2028, and no results have yet been generated.

Background Temperature instability during neonatal transport contributes to adverse outcomes in preterm and low birth weight infants. Hypothermia in this population is associated with increased risk of intraventricular haemorrhage (IVH), sepsis, and death. Current transport temperature management is reactive and manually controlled. The Heating On Transport WitH prEtErm and Low birth weight neonates using Servocontrol patient temperature management system (HOTWHEELS) trial aims to determine whether automated, servo-controlled thermoregulation provides superior thermal stability compared to standard care and reduces hypothermia-associated adverse outcomes. Methods This prospective, randomised, superiority trial is conducted by the Newborn Emergency Transport Service of Western Australia. Infants with a gestational age of less than or equal to 34 weeks and/or weight of 1500 g requiring transport are randomised to serve-controlled or standard thermal care. The primary outcome is the proportion of infants with a temperature between 36.5 and 37.5 degrees Celsius on arrival at the receiving neonatal unit. Secondary outcomes include the incidence of IVH in the first 7 days, mortality before discharge, the incidence of moderate (<36.0) and severe (<35.0) hypothermia for greater than 15 minutes and the temperature change during transport. Trial registration: ANZCTR12624000503527. Impact HOTWHEELS is the first randomised trial in neonatal transport to evaluate servo-controlled temperature control. We believe the findings will inform standards of temperature control during transport for preterm and low birth weight infants.

Objectives To investigate the association between time spent in NHS Type 1 emergency departments (EDs, consultant led 24 hour services with full resuscitation facilities) and risk of leaving employment and hospitalisation after leaving the department alive up to two years after attendance. Methods We conducted a retrospective cohort study using linked administrative data from the NHS Emergency Care Dataset, Hospital Episode Statistics, Census 2021, and mortality records. ED length of stay was categorised from under 2 hours to 12 hours or more. Cox proportional hazards models were fitted to estimate the association between ED length of stay and subsequently leaving employment or being hospitalised over a two year follow-up period, adjusting for demographic, socioeconomic, and clinical characteristics. Results Our study population comprised 3,347,008 individuals aged 25 to 64 who attended a Type 1 ED in England between April 2021 and March 2023. For leaving employment, adjusted hazard ratios (aHRs) increased from 1.04 (95% CI 1.03 to 1.06) for stays of 2 to <4 hours to 1.21 (1.17 to 1.24) for 12 hours or more, compared with stays under 2 hours. A similar but more pronounced gradient was observed for post-discharge hospitalisation, with aHRs rising from 1.06 (1.04 to 1.07) at 2 to <4 hours to 1.95 (1.91 to 1.99) for stays of 12 hours or more. Conclusions Prolonged time spent in the ED is associated with poorer outcomes among working-age employees, including reduced labour market participation and increased hospital use. These findings suggest that long ED stays may have wider and longer-term implications beyond immediate clinical outcomes, including potentially for national labour markets and economic growth.

Across the UK, older adults in deprived areas like Barnsley are spending more of their lives in poor health. Alongside increased loneliness, this creates barriers to leading active healthy lives that can lead to decreases in the quality of life of residents and increased pressure on healthcare services. To address these issues, Barnsley Council brought together over 80 providers of physical activity classes for adults aged 50 and over as part of a joined up partnership called the Barnsley Older People Physical Activity Alliance (BOPPAA). The evaluation will explore how effectively the joined up partnership (BOPPAA) works in helping older adults lead active health lives by collecting information on involvement in the classes, and speaking to residents and organisations to get their thoughts and opinions. The findings will be used to help understand how BOPPAA can be improved to better meet the needs of the local population.

Background: As musculoskeletal physiotherapy evolves toward advanced practice and direct access, evaluating high levels of clinical competence has become pressing. Quality indicators underpin large-scale audit systems, but indicators discriminating advanced competence remain insufficiently defined. Objective: To identify and characterize indicators capable of discriminating high levels of clinical competence in musculoskeletal physiotherapy. Methods: A modified Delphi comprised an exploratory pre-round and two consensus rounds. Experienced French-speaking musculoskeletal physiotherapists were recruited using an expertise scoring grid. Candidate indicators, generated from open-ended responses and existing quality indicators, were rated on 6-point Likert scales for relevance, formulation, and tool adequacy. Consensus was predefined as [&ge;]75% of ratings [&ge;]5. Results: Thirty-two experts completed the pre-round, 29 the first round, and 27 the second (84% retention), generating 49 candidate indicators. Thirteen reached consensus for relevance, and 10 also for formulation. Retained indicators primarily reflected advanced clinical reasoning: real-time adaptation, hypothesis prioritization, decision-making under uncertainty, and error management. Only one outcome indicator reached consensus: clinical performance weighted by case complexity. Conclusion: High levels of clinical competence in musculoskeletal physiotherapy appear characterized less by standardized outcome attainment than by managing complexity, uncertainty, and error through advanced clinical reasoning. These findings may inform competence-oriented audit and feedback systems. Trials registration: Not applicable.

Background: Robot-assisted radical prostatectomy is the standard minimally invasive treatment for localized prostate cancer. Conventional multiport robotic surgery is widely applied yet associated with more abdominal trauma and postoperative discomfort. Single-port robotic surgery can further minimize surgical injury. The domestic KangDuo robotic system has been gradually used in urological oncology, but high-level prospective evidence comparing single-port and multiport extraperitoneal radical prostatectomy remains scarce. This trial aims to compare the efficacy and safety of these two surgical approaches. Methods: This is a single-center, prospective, 1:1 randomized, non-inferiority trial. Eligible patients diagnosed with cT1c-cT2cN0M0 localized prostate cancer will be randomized to receive either single-port (experimental group) or multiport (control group) extraperitoneal robotic radical prostatectomy using the KangDuo system. All participants will receive standardized enhanced recovery after surgery (ERAS) protocols. The primary endpoint is postoperative positive surgical margin rate. Perioperative parameters, postoperative recovery, medium-term functional recovery and oncological outcomes will be assessed comprehensively. Expected results: We hypothesize that the single-port approach is non-inferior to the multiport approach in terms of oncological radical effect. The single-port technique is expected to provide better minimally invasive benefits, with comparable perioperative safety, urinary/sexual function recovery and mid-term oncological outcomes between groups. Conclusions: This randomized trial will provide high-quality clinical evidence for the application of domestic single-port robotic surgery. The findings will facilitate individualized surgical selection for patients with localized prostate cancer.

IntroductionCurrent evidence suggests that patient health passports may improve care for patients with chronic illnesses. This systematic review aimed to evaluate the impact of patient health passports on health outcomes in adults with diabetes. MethodsA systematic review was conducted in February 2025 following PRISMA 2020 guidelines, using Ovid MEDLINE, Ovid EMBASE, EBSCO CINAHL, Web of Science, and Scopus. The review included studies of adult diabetic patients using paper or digital patient health passport as part of their care in comparison with the standard of care. Data were analysed using meta-analysis and a thematic analysis where appropriate; otherwise, the data are presented narratively. Quality appraisal was undertaken using the Cochrane Collaboration tool for assessing risk of bias and Evidence-based librarianship checklist. The certainty of the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation. ResultsEleven studies (n=14,350) were included. Seven studies were randomised controlled trials, two were retrospective in nature, one was a qualitative and one was a pre-post study. Overall, the studies are limited in design, resulting in high or unclear risk of bias across multiple domains. Results of the meta-analysis of five studies showed a statistically significant mean difference reduction in HbA1c and total cholesterol in favour of the intervention group; however, the certainty of the evidence is low or very low. The narrative analysis of the data revealed little to no improvement in body mass index, blood pressure, blood glucose, and cholesterol levels. Patients opinions and perceptions revealed some benefits in usability, perceived value, and in enhancing collaboration. ConclusionThis review provides evidence suggesting that patient health passports may improve patient care and can inform the design of future high-quality studies. However, the low certainty of the evidence highlights the need for high-quality studies with larger sample sizes. Key PointsO_LIPatient health passports show promise in enhancing diabetes management, however current evidence is limited by high risk of bias; future high-quality studies are required to confirm efficacy. C_LIO_LINurses are pivotal in this process as they play a central role in diabetes education, self-management support and continuity of care. C_LIO_LIPatient health passports could be considered as a structured tool to facilitate ongoing monitoring, reinforce adherence, enhance communication between patient and nurses/multidisciplinary team.

Background: Multidisciplinary tumor boards (MTBs) are a standard part of cancer care, yet India has no national measure of how many cancer patients are discussed at one. A national survey of hospitals in the National Cancer Registry Programme (NCRP), published in 2026, gives the first structured look at board presence and functioning. Objective: To describe how far hospital-level tumor board presence translates into all-case review, documentation and follow-up, and to define the data needed to measure patient-level coverage. Methods: Secondary analysis of published aggregate data: the ICMR-NCDIR survey of 229 hospitals in the NCRP hospital-based cancer registry (HBCR) network (October 2024), the HBCR 2021 report, national incidence estimates (ICMR-NCDIR 2022; GLOBOCAN 2024) and two published single-center MTB audits. We calculated proportions with Wilson 95% confidence intervals, non-response bounds across all 229 hospitals, and logical bounds for joint conditions. No individual-level data were used. Results: A total of 229 hospitals were invited and 172 responded (75.1%). Among the respondents, 137 (79.7%; 59.8% to 84.7% across all hospitals) reported a functional tumor board. Only 65 respondents (37.8%; 28.4% to 53.3%) reported boards that review all cases, 71 (41.3%) had a follow-up system, 50 (29.1%) used any electronic documentation and 7 (4.1%) always took part in cross-hospital reviews. The share of hospitals with both all-case review and a follow-up system could lie anywhere from 0% to 37.8% of respondents. Boards were reported more often in private (86.6%) than in public hospitals (72.5%). Two single-center audits reported about 800 case discussions (573 new patients) and 1,260 case discussions (about 917 patients) a year, but neither reported new registrations at the same hospital, so coverage could not be calculated. Conclusions: Tumor board presence is common in India, but evidence of all-case review, documentation and follow-up is much thinner, and the share of patients reviewed nationally is unknown. We propose six indicators that hospital-based registries could report to measure coverage directly.

Background Chronic subdural hematoma (CSDH) is common and increasing in incidence. Short-term post-surgical outcomes are good, but longer term, patients experience increased morbidity and early mortality than controls and the general population. Deprivation and ethnicity affect many health conditions, but to our knowledge, this is the first UK study investigating their association with CSDH outcomes. Methods This single-centre retrospective cohort study used Secondary Uses Service Admitted Patient Care Spells (SUS+ APCS) data. Adult subdural hematoma (SDH) patients admitted to St Georges Hospital, London treated with burr-hole surgery between April 2022 and April 2025 were included. Primary outcomes were initial length of stay (LoS) and days spent hospitalised in the subsequent year. Deprivation was measured using Index of Multiple Deprivation (IMD). Linear regression models estimated initial LoS and subsequent days spent hospitalised by category, adjusted for factors including age, ethnicity and comorbidities. Results In this single-centre cohort of 449 patients, IMD was not associated with initial LoS, but was significantly associated with subsequent time spent hospitalised. In a log-transformed linear regression model, the most deprived spent 4.5-times longer hospitalised during the year after CSDH than the least deprived (fold change = 4.45, 95% confidence interval (95%CI) 2.20 to 9.01). Conclusions Higher neighbourhood-level deprivation was associated with time spent hospitalised following CSDH. This was robust to adjustment for potential mediating factors. This is the first UK study demonstrating health inequalities in CSDH outcomes, highlighting a need for future research to gain further insights, and to improve equity of outcomes after CSDH.

Background: Capillary refill time (CRT) is an increasingly endorsed bedside perfusion marker in septic shock.Publicly available intensive care unit (ICU) databases such as MIMIC-IV and eICU-CRD enable large-scale multi-database research, but the cross-database comparability of CRT operationalization has not been systematically examined. Methods: We conducted a retrospective, descriptive, cross-database methodological analysis of adult ICU stays in MIMIC-IV v3.1 (2008-2022) and eICU-CRD v2.0 (2014-2015). CRT availability, definitional thresholds, recording patterns and time windows, bilateral measurement consistency, and selection bias in the CRT-documented population were characterized descriptively. Results: Among 94,458 MIMIC-IV and 200,234 eICU-CRD adult ICU stays, CRT availability differed markedly:79.85% of MIMIC-IV stays had at least one CRT record within the first 24 hours, versus 6.35% of eICU-CRD stays across the entire ICU stay, a 73.5-percentage-point gap. The abnormality threshold was 3 seconds in MIMIC-IV and 2 seconds in eICU-CRD. Among CRT-available MIMIC-IV stays, the mean number of CRT records in the first 24 hours was 7.0 (median 6, interquartile range (IQR) 4-10); 99.6% had bilateral records, with 99.4% left-right agreement (Cohen's kappa 0.914). The temporal distribution of CRT records was strikingly similar between databases: only 28.7% of MIMIC-IV and 29.1% of eICU-CRD records occurred within 24 hours of ICU admission (including pre-admission records), with roughly 71% in both databases recorded later in the stay. In eICU-CRD, the CRT-documented population had higher illness severity than the undocumented population (Acute Physiology and Chronic Health Evaluation (APACHE) IV 60.0 versus 54.4; standardized mean difference 0.21), consistent with selection by indication. Structured peripheral perfusion index fields were unavailable in both databases. Conclusions: CRT operationalization differs fundamentally across MIMIC-IV and eICU-CRD in availability, definitional thresholds, recording patterns, bilateral structure, and patient selection. Cross-database CRT research should explicitly declare definitional heterogeneity, avoid pooling across thresholds, and treat sparsely documented subsets as selected populations. Selection bias was evident in both databases, in opposite directions. Severity-score-based comparison was possible only in eICU-CRD. Standardized common data elements for bedside perfusion assessment are needed to make cross-database CRT research valid by design.

Background While overall application volume by ethnic minority doctors into UK postgraduate medical training has expanded significantly, workforce diversity varies substantially across specialties. Previous reports have suggested that doctors from certain ethnic backgrounds and international medical graduates (IMGs) experience lower likelihoods of securing training posts, but granular longitudinal evaluations across all specialty training levels and recruitment stages remained limited. Therefore, this study evaluates longitudinal trends in self-reported ethnicity and country of qualification across postgraduate medical training in England between 2021 and 2025, maps specialty representation, and tests the hypothesis that recruitment success rates differ significantly between ethnic minority and White baseline applicants. Methods We conducted a retrospective national longitudinal analysis of mandatory NHS specialty recruitment data across England from 2021 to 2025, encompassing over 300,000 applications across ST1/CT1 (entry-level) and ST3+ (higher specialty) pathways. Applicants were categorised into census-aligned broad and granular ethnic groups, alongside IMG classifications. Unadjusted odds ratios (ORs) with 95% confidence intervals were calculated using White graduates and internal sub-ethnic baselines as comparators. Specialty-level ecological correlations (Spearman's rho) were performed to evaluate whether international workforce reliance moderated ethnic recruitment disparities. Results Between 2021 and 2025, applicant volume expanded rapidly, with ethnic minority applicants and IMGs comprising numerical majorities. However, Asian and Black applicants experienced substantially lower odds of receiving training offers compared to White baseline applicants across multiple high-volume specialties (e.g., emergency medicine and anaesthetics at ST1, where Black applicants faced multi-fold reductions in success odds: OR 0.03 to 0.05, p<0.001). Granular analyses revealed notable intra-ethnic heterogeneity, including lower success among Pakistani and Bangladeshi applicants compared to Indian applicants. Furthermore, UK graduates maintained higher offer success than IMGs across most specialties. Ecological correlations demonstrated that higher international applicant reliance was moderately and significantly associated with wider recruitment disparities at higher training levels for Black applicants {rho}=-0.43, p=0.019). Conclusions Centralised medical recruitment in England exhibits some persistent ethnic and international qualification disparities despite rising application diversity. The findings highlight the necessity of disaggregating ethnic groups and addressing subjective evaluation vulnerabilities within multi-stage recruitment processes to foster equity.

Background/Aims This work aimed to estimate the annual tertiary healthcare and societal costs associated with paediatric congenital heart disease (CHD) in the United Kingdom using real-world data from a Level 1 cardiac surgical centre in the National Health Service (NHS). Methods A prevalence-based cost-of-illness analysis was conducted using patient-level inpatient and outpatient activity data from Evelina London Children's Hospital between 1 June 2023 and 31 May 2024. Costs were estimated from NHS and societal perspectives and extrapolated to national level using National Congenital Heart Disease Audit (NCHDA) procedural activity data. Healthcare costs included tertiary centre care costs. Societal costs included parental productivity losses and impacts on lifetime earnings for children. Deterministic sensitivity analysis explored parameter uncertainty. Results Approximately 9.6% of UK paediatric CHD procedures were undertaken at Evelina London Children's Hospital at a cost of {pound}15.0 million per annum, corresponding to a national estimate of {pound}156.4 million. Single-ventricle procedures accounted for 4.8% of inpatient activity but 19.4% of inpatient costs. Sensitivity analysis produced national healthcare cost estimates ranging from {pound}125.1 million to {pound}187.7 million. National productivity losses associated with parental absence from work were estimated at {pound}82.4 million annually. Individuals with CHD were estimated to experience a mean reduction in lifetime earnings of {pound}81,509. Conclusion Paediatric CHD imposes a substantial economic cost on the UK healthcare system and wider society. This study provides the first real-world national estimate of the economic impact of paediatric CHD in the UK and may inform future service planning, research investment, and innovation adoption strategies.

Background: Although point-of-care testing is the standard method for inpatient glucose monitoring; it is associated with patient discomfort and late detection of dysglycaemic events. Continuous glucose monitoring (CGM) may improve glycaemic management; however, limited staff education and experience among may hinder its implementation. Aim: To investigate experience, perceptions and training needs on CGM use among inpatient nursing staff across diverse hospital wards. Methods: This is a single-centre, 38-item online survey recruited inpatient nurses in a hospital in the UK. Participants were invited via the e-newsletter and posters; the survey remained open for five months. Results: Nineteen nurses reported positive perceptions of inpatient CGM. Most considered CGM reliable (77.8%) and preferred CGM combined with POCT (66.7%). Views on its impact on workload and patient-room entries were mixed (30% agreed, 30% disagreed). Training needs included sensor placement (92.9%) and alarm management (78.6%). Conclusion: Nurses viewed CGM favourably but highlighted important training needs for inpatient use.

Introduction: Primary care electronic health records (EHRs) are an important resource for health research, but death recording in primary care EHRs may be incomplete or differ from Office for National Statistics (ONS) death registrations. We used OpenSAFELY-TPP to assess the completeness and concordance of death recording and provide recommendations for using date-of-death information. Methods: Using linked primary care EHRs and ONS death registrations, we assessed whether ONS-registered deaths from 2020-2025 had a primary care date of death and, where present, calculated the difference between dates. Where a primary care date was absent, we assessed death-related SNOMED CT codes. Analyses were conducted overall and by year, population subgroup, and general practice. We also examined GP registration end dates and primary-care-recorded deaths without a corresponding ONS record, including monthly patterns near the data extraction date. Results: Among 1,409,275 ONS-registered deaths, 88% had the same date recorded in primary care and 8% had no corresponding primary care date. Among 1,324,995 deaths recorded in primary care, <2% had no corresponding ONS record. Deaths recorded in only one source were more frequent among people aged <45 years and those from Mixed, Asian or Asian British, Black or Black British, and Chinese or Other ethnic groups. ONS-only dates were also more frequent in London and the West Midlands. Primary-care-only deaths increased close to date of data extraction, reaching 7% in February 2026. Same-day GP deregistration increased from 9% in 2020 to 85% in 2025. Conclusions: Death recording in primary care EHRs showed high completeness and concordance with ONS registrations, but discrepancies remained for recent deaths and some population groups. Data recency and population-specific completeness should therefore be considered when using linked mortality data for research.
