To develop survey items for a national patient registry on Long COVID using a modified Delphi process.
This study was based on a modified Delphi process involving three rounds of anonymous, online surveys to develop consensus on and prioritise survey elements to be included in a minimum dataset for use in a national patient registry in Canada. Initial Long COVID items were identified through an environmental scan of the literature.
This study focused on healthcare systems in Canada and was conducted online.
A panel of 52 experts (patients, caregivers, clinicians and researchers) participated in all three rounds of the online survey. These participants were recruited through the Long COVID Web network and word of mouth.
In total, 243 survey elements related to care, quality of life and symptoms were included in round 1 of the survey. 200 reached consensus and moved to round 2 with two additional elements being developed based on open-ended responses. In round 2, participants ranked these survey elements and 34 advanced. In round 3, 33 survey elements met the threshold of consensus with one added a priori. The 33 survey elements were then used to develop a Long COVID minimum dataset, which consists of 48 items.
The findings affirm broad consensus for collecting data related to fatigue, post-exertional malaise, cardiovascular issues, respiratory problems and cognitive issues. This highlighted the desire for quality-of-life indicators and information related to care utilisation, quality and access.
Patients who survive admission to intensive care unit (ICU) for critical illness are at high risk of developing muscle atrophy and weakness, commonly diagnosed as ICU-acquired weakness (ICUAW). The development of ICUAW is closely linked to long-term symptoms and impairments known as post-intensive care syndrome (PICS). Despite heightened recognition of impairments, there is limited research supporting effective interventions to improve muscle and physical outcomes after hospital discharge. Prior to developing and testing interventions for ICU survivors, it is imperative to understand the trajectory of muscle and physical function recovery following an ICU stay. The purpose of this study is to longitudinally investigate skeletal muscle health and physical function outcomes after ICU admission.
This protocol describes a single site, prospective, observational study in adult patients who have survived a critical illness (ie, sepsis or acute respiratory failure). Patients will participate in a battery of testing including primary outcomes: muscle power and physical function; and secondary outcomes: muscle strength, muscle size, endurance and physical activity (by accelerometry) at hospital discharge and 3, 6, and 12 months post-discharge. A subset of patients will participate in muscle biopsy and venipuncture. To examine if the trajectory of recovery predicts primary outcomes, we will perform multivariate linear regression models in 150 evaluable patients. To examine differences in molecular and cellular outcomes in plasma and muscle tissue, a control group of community-dwelling adults without history of an ICU stay will be enrolled as a comparator group. Enrolment started on 18 October 2022 with an estimated completion date of 1 August 2027.
This protocol was approved by the University of Kentucky Office of Research Integrity Medical Internal Review Board (# 77407), with patients providing informed written consent. We anticipate our findings to establish recovery trajectories, improving the classification of patients who experience sustained physical disability. Improved identification of recovery trajectories of muscle and physical function enables future studies to employ an individually targeted rehabilitation approach, that is, precision medicine, with the goal of improving patient outcomes. The cellular findings will support the development of novel interventions specifically designed for detecting underlying mechanisms. We intend to disseminate findings to patients, healthcare professionals, the public and other relevant groups via conference presentations and manuscripts without publication restrictions.
To determine what drives participation in clinical trials with decentralised elements and to estimate trial participation probabilities for trials with different degrees of decentralisation.
Patient preference study using a discrete choice experiment.
Recruitment in primary, secondary, tertiary care and other settings in the Netherlands (NL), Austria (AT) and Germany (DE).
People with type 2 diabetes mellitus (T2DM) aged ≥18 years. A total of 787 people (NL n=276, AT n=265, DE n=246) participated in the study.
Preferences for participation in clinical trials with different options for location and type of contact with the study team, activities to perform by participant, use of digital technologies by participant, number of scheduled contacts, trial duration, known safety and efficacy of the drug.
How much was known about the safety and efficacy of the drug was the most important element in the decision whether to participate in a clinical trial in all countries. The trial duration, location and type of contact with the study team, and number of scheduled contacts were other important elements. Participation probabilities for hypothetical trial scenarios differed between countries, with the highest rates for a decentralised trial involving video contact (NL: 89%; AT: 99%; DE: 84%).
People with T2DM prefer to take part in clinical trials with decentralised approaches. Information on preferences can help trialists and protocol developers to design and plan future trials that integrate patients’ needs and thus reduce barriers to participation.
Implementation science research increases the uptake of evidence-based interventions, which may improve health equity among racial and ethnic minorities. However, it is unclear how anti-racism and anti-colonialism practices have been integrated into implementation science research. The objectives of this scoping review are to describe the current conceptualisations of racism and colonialism within the USA, examine racism or colonialism-conscious approaches and analyse gaps in the operationalisation of anti-racism or anti-colonialism within implementation science studies.
This scoping review will be conducted following the Preferred Reporting Items for Systematic Reviews and Meta-analyses extension for scoping reviews guidelines. The Center for Chronic Disease Reduction and Equity Promotion Across Minnesota conceptual framework and an implementation science anti-racism lens will guide the study design and analysis. To determine study eligibility for the scoping review, articles will undergo abstract and full-text screening by two independent reviewers and discrepancies will be settled together. Data charting will be extracted from included articles by eight independent reviewers. The search strategy will use controlled vocabulary and natural language keywords related to health equity, health disparities and anti-racism/colonialism on six databases. The scoping review will include studies that applied implementation science theories, models or frameworks among US-based populations. Additionally, included studies will report any of the following implementation activities: implementation strategies, implementation outcomes, adaptations to evidence-based interventions, or evaluations of pre-implementation or implementation context.
No ethical approval was required for the scoping review. Dissemination will be through publication in a peer-reviewed journal and conference presentations.
The rapidly growing population of older adults (individuals aged 65 years and older) presents a new set of challenges for healthcare providers in the emergency department (ED), given the prevalence of severe and life-threatening conditions among this group, such as chronic cancer, Alzheimer’s disease/dementia and congestive heart failure. ED encounters often represent a critical point in an older patient’s trajectory of care and can thus be an important opportunity for various interventions such as palliative care consultation. Therefore, identifying those who will benefit most from palliative care is of high importance, especially in determining the course of future treatment. Thus, we aim to conduct a systematic review assessing the efficacy of palliative care screening in the ED by assessing inpatient length of stay as the primary outcome and quality of life, percentage of hospitalisation and cost of care as secondary outcomes.
This study will use Ovid MEDLINE, Embase, EBSCO CINAHL, Web of Science and Cochrane as databases. The study population comprises adults aged 60 years and older, with no focus on any specific clinical specialty or disease. Patients who have not received palliative care screening will serve as the comparator. Only studies with an applicable comparator will be considered. Studies published from 1 January 2000 to 1 July 2025 will be included.
All articles will be reviewed independently and in duplicate, and every author will participate in the review, data abstraction and conflict resolution process.
Ethical approval is not required as it is a protocol for a systematic review. Findings will be disseminated through peer-reviewed publications and conference presentations.

The aim of this study was to prioritise a set of indicators to measure World Health Organization (WHO) quality-of-care standards for small and/or sick newborns (SSNB) in health facilities. The hypothesis is that monitoring prioritised indicators can support accountability mechanisms, assess and drive progress, and compare performance in quality-of-care (QoC) at subnational levels.
Prospective, iterative, deductive, stepwise process to prioritise a list of QoC indicators organised around the WHO Standards for improving the QoC for small and sick newborns in health facilities. A technical working group (TWG) used an iterative four-step deductive process: (1) articulation of conceptual framework and method for indicator development; (2) comprehensive review of existing global SSNB-relevant indicators; (3) development of indicator selection criteria; and (4) selection of indicators through consultations with a wide range of stakeholders at country, regional and global levels.
The indicators are prioritised for inpatient newborn care (typically called level 2 and 3 care) in high mortality/morbidity settings, where most preventable poor neonatal outcomes occur.
The TWG included 24 technical experts and leaders in SSNB QoC programming selected by WHO. Global perspectives were synthesised from an online survey of 172 respondents who represented different countries and levels of the health system, and a wide range of perspectives, including ministries of health, research institutions, technical and implementing partners, health workers and independent experts.
The 30 prioritised SSNB QoC indicators include 27 with metadata and 3 requiring further development; together, they cover all eight standard domains of the WHO quality framework. Among the established indicators, 10 were adopted from existing indicators and 17 adapted. The list contains a balance of indicators measuring inputs (n=6), processes (n=12) and outcome/impact (n=9).
The prioritised SSNB QoC indicators can be used at health facility, subnational and national levels, depending on the maturity of a country’s health information system. Their use in implementation, research and evaluation across diverse contexts has the potential to help drive action to improve quality of SSNB care. WHO and others could use this list for further prioritisation of a core set.
The predisposition to food allergy development and the induction of allergen-specific immune responses appears to be initiated early in infancy. Early exposure to food allergens, such as peanut and cashew nut, via human milk is likely important in initiating oral tolerance and reducing risk of food allergy development. This trial aims to determine if the risk of developing peanut and cashew nut allergy during infancy can be reduced by a high peanut and cashew nut maternal diet during lactation.
This is a multisite, parallel, two-arm (1:1 allocation), single-blinded (outcome assessors, statistical analyst and investigators), randomised controlled trial. Target sample size is 4412 participants (2206 per group). Women (aged 18–50 years) with a singleton pregnancy, who are planning to breastfeed and do not have peanut and/or cashew nut allergies are eligible to participate. After obtaining written informed consent, participants are randomised to either a high peanut and cashew nut diet (at least 60 peanuts and 40 cashew nuts per week) or a low peanut and cashew nut diet (no more than 20 peanuts and 12 cashew nuts per week). Participants are asked to follow their allocated diet from birth to 6 months postnatal. Individual lactation consultant advice and support is provided as required. The study’s primary outcome is food challenge proven IgE-mediated peanut and/or cashew nut allergy during infancy (0–18 months). Key secondary outcomes include infant sensitisation to peanut and/or cashew nut. Analyses will be performed on an intention-to-treat basis according to a prespecified statistical analysis plan.
Ethical approval has been granted from the Western Australian Child and Adolescent Health Service Human Research Ethics Committee (approval number RGS0000006685). Trial results will be presented at scientific conferences and published in peer-reviewed journals.

Length-for-age z-scores (LAZ) and stunting prevalence (%LAZ
We simulated a synthetic cohort with a harmonically downward-shifting LAZ trajectory from birth to 24 months of age, with mean LAZs similar to the HBGDki pooled South Asian cohorts, and without any input parameters intended to differentially affect individuals’ growth across the height distribution or at different ages. We compared HBGDki empirical estimates of age interval-specific frequencies of incident stunting onset and stunting reversal with those from the synthetic cohort. Using synthetic cohorts, we examined how estimates of incident onset and reversal were affected by missing data, magnitude of the whole-population shift in the LAZ distribution and strength of the between-time-point correlation. We also compared the 3–24 month pattern of linear growth faltering expressed as age-related trajectories of average growth delay (chronological age minus height–age), mean LAZ or stunting prevalence.
Empirical estimates of age interval-specific incident stunting onset and stunting reversal in the HBGDki cohorts were similar to those observed in a synthetic cohort. Variability in LAZ threshold-crossing event rates is explained by starting LAZ, between-time-point correlation and the magnitude of the whole-population shift in the LAZ distribution. Incident stunting onset is also affected by missing data in preceding intervals. Stunting reversal occurs due to within-child variability (ie, imperfect between-time-point correlation) in the absence of any other phenomena that cause stunted children to become non-stunted at a later age. The linear growth faltering pattern based on growth delay differed from corresponding age-related trajectories of mean LAZ or stunting prevalence.
In longitudinal studies of linear growth faltering in LMICs, LAZ threshold-crossing indicators are byproducts of whole-population shifts in LAZ and within-child variability and should be interpreted accordingly. Reporting incident stunting onset and reversal rates, or analyses in which children are grouped by the timing of LAZ threshold-crossing events, may detract from efforts to understand when and why nearly all children in LMICs grow more slowly than expected for their age. Since mean LAZ and stunting prevalence are unsuitable for quantifying the rate and timing of population-average postnatal linear growth faltering, growth delay is recommended for consideration as a preferred metric.
To quantify and describe the use of real-world data (RWD) in National Institute for Health and Care Excellence (NICE) oncology technology appraisal (TA) final appraisal determination documents.
A systematic literature review was conducted on pharmaceutical NICE oncology TAs published between April 2000 and March 2024 (covering financial years 2000/2001 to 2023/2024 inclusive) extracted on 22 August 2023 (2000/2001 - 2022/2023) and 8 August 2024 (2023/2024).
NICE TA final appraisal determination documents.
All pharmaceutical oncology TAs published between April 2000 and March 2024 (financial years 2000/2001 to 2023/2024) that did not go on to be terminated.
The data required for eligibility screening was extracted from an Excel file directly from the NICE website, where data related to each TA was extracted using an automated script derived from published sources. TAs were assessed based on prespecified review criteria covering whether an RWD submission was reported by the committee, and if so, which RWD sources were used, alongside the methods reported and any feedback from the committee regarding the use of RWD. Bias was not assessed as part of the study.
Of 310 TAs identified, 135 (48.0%) used RWD. A variety of RWD types were used, mostly from UK or US data sources. 47 TAs (34.8%) leveraged RWD from multiple sources. RWD was mostly used in comparisons of survival (41.5%), to inform utility values (26.7%) and to compare baseline characteristics (19.3%), with matched adjusted indirect comparisons (MAICs) and external control arms (ECAs), seen from 2015 and 2018, respectively. The committee expressed concerns around the RWD presented by the company in 53 TAs (39.2%), the most common being a lack of generalisability to the UK population and/or National Health Service practice and comprehensiveness of the RWD.
This study quantifies the increasing use of diverse RWD sources in NICE oncology TAs, as well as the shift towards more complex methods like MAICs and ECAs. The feedback of the NICE committee highlights key areas of improvement as the generalisability and maturity of the RWD presented.
In moderate to high-risk surgical procedures, 15–25% of patients develop a postoperative surgical site infection. Intraoperative incisional wound irrigation has the potential to reduce surgical site infections, and additional randomised controlled trials are required to provide evidence of effectiveness.
This protocol describes a pragmatic, adaptive, participant and adjudicator-blinded trial at 13 sites in Canada in up to 2500 participants. Participants planned for surgery with an abdominal or groin incision, who are eligible and provide verbal consent through an integrated consent model, are randomised to receive intraoperative incisional wound irrigation with povidone-iodine, saline or no irrigation. The primary outcome is surgical site infection within 30 days postoperatively. Secondary outcomes include quality of life measured 30 days postoperatively and morbidity, mortality and healthcare utilisation within 90 days postoperatively.
This trial has been approved by the research ethics board at the participating centres and stopped enrolling participants on May 23, 2025. All participants will provide verbal consent. Results will be disseminated via presentation at conferences, publication and posted on clinicaltrials.gov.
