Colorectal cancer (CRC) is one of the most common cancers worldwide. Stage II/III patients undergo curative-intent surgery yet still face the recurrence risk. Detecting recurrences early provides the best opportunity for optimal treatment. We aimed to develop a microsimulation model to evaluate CRC management-associated outcomes based on current guidelines, including the performance of guideline-recommended surveillance in detecting recurrences.

Two separate individual-level state transition (microsimulation) models for colon and rectal cancer were built with a lifetime horizon using monthly cycles. The models integrated treatment and surveillance strategies per current guidelines.

The currently recommended surveillance modalities by National Comprehensive Cancer Network guidelines for surveilling patients with CRC after curative-intent surgery.

65-year-old patients with stage II and stage III CRC who underwent curative-intent surgery in the USA.

Cumulative recurrences, detected recurrences, detection rate, overall survival and recurrence-free survival in a 5-year horizon, as well as average life expectancy, were the outcome measures used.

Over 5 years, disease recurrence was observed in 9.5% of patients with stage II–III colon cancer and in 38.0% of patients with stage II–III rectal cancer. Of these, 82.5% and 85.5% were detected via surveillance, respectively, within 5 years. The predicted 5-year overall survival was 86.0% for colon cancer and 69.3% for rectal cancer, with corresponding recurrence-free survival rates of 78.9% and 53.8%. Based on current guidelines-recommended surveillance, detecting one colon cancer recurrence requires 148 carcinoembryonic antigen (CEA) tests, 37 CT scans and 21 colonoscopies. In contrast, detecting one rectal cancer recurrence requires 31 CEA tests, 8 CT scans and 4 colonoscopies.

Our validated model suggests that relative to an optimal benchmark in which all recurrences are detected, recurrence detection under current guidelines may be suboptimal, indicating room for improvement. As new tests emerge, this model could be a valuable tool for evaluating existing clinical practices and the potential of new tests to enhance patient outcomes.

Age acceleration in survivors of breast cancer is a critical issue because cancer and its treatment can increase structural and numerical chromosomal aberrations, while simultaneously shortening telomere length and changing ageing phenotype. Therefore, the current study will be using machine learning architectures to accurately predict the factors that contribute to age acceleration among survivors of breast cancer.

The Cancer Survivors’ Trajectories of Ageing Research (C*STAR) is a hospital-based cross-sectional study involving multi-ethnic Malaysian survivors of breast cancer and a non-breast cancer control group, frequency-matched by age group (±5 years), sex and ethnicity. The three main stages of this study will be conducted in the predictive model development. First, a set of validated questionnaires will be used to collect the data on modifiable factors of ageing phenotypes and behavioural determinants of health. Second, 3 mL non-fasting blood samples will be collected, and lymphocytes will be isolated to determine telomere length using real-time PCR as a biomarker of age acceleration. Lastly, a machine learning architecture will be deployed to identify modifiable factors that may contribute to age acceleration in survivors of breast cancer and controls, with these factors used as input and ageing biomarkers of telomere length as output. The study outcomes may serve as guidance to enhance the quality of life of survivors of breast cancer and hinder the recurrence of cancer while ageing successfully.

Ethical approval was obtained from the Research Ethics Committee, Universiti Kebangsaan Malaysia (JEP-2022-700) to carry out this study. Written informed consent will be obtained from each survivor of breast cancer and each cancer-free woman prior to participation. The results of this study will be published for future research and clinical applications.

There are limited data about how South Asian (SA) patients, their caregivers and their physicians make decisions about treatment, in particular advanced therapies. The study aimed to explore how SA people with inflammatory bowel disease (IBD), their family members and clinicians experience and perceive treatment-related decision-making with the aim of identifying strategies to improve treatment decision-making in Canada.

A descriptive qualitative study with in-depth semi-structured interviews.

Canada.

Adults residing in Canada, who self-identified as SA, had received treatment or cared for someone who received treatment for IBD from a gastroenterologist in Canada, and who spoke and understood English, Hindi and/or Punjabi were eligible to participate in the study. Clinician participants (eg, nurses, gastroenterologists, colorectal surgeons) were eligible if they had experience treating SA patients with IBD.

Data from 1:1, semi-structured interviews were analysed using deductive and inductive thematic analysis.

The length of time spent in Canada played a central role in patient perspectives on decision-making around IBD treatment. First or second-generation SA people, residency status, family and community involvement, universal factors like stigma, medication costs and preferences for non-pharmacological treatments influenced decision-making. Patient and caregiver participants reported high satisfaction with treatment-related decision-making processes, while clinician participants self-reported lesser satisfaction.

Clinicians and researchers working with SA patients in chronic disease specialties can use these findings to meet the healthcare needs and reduce disparities in optimal treatment for this patient population.

Surgery and its resulting hospitalisation are associated with subsequent cognitive and functional decline. Interventions to reduce this decline have exhibited limited success. Prehabilitation is the process of enhancing capacity and reserve before an acute stressor to improve tolerance of the acute physiologic insult. Older adults requiring major surgery are an ideal population for prehabilitation. Prehabilitation exercise studies have mostly focused on physical training to improve physical outcomes after specific surgery types, and data on cognitive outcomes and in broader surgical populations are needed. Computerised cognitive training (CCT) has been shown to enhance memory, processing speed, attention and multitasking. Combining CCT with a physical exercise may be most effective in reducing cognitive and functional decline in older patients undergoing major surgery, but has yet to be evaluated.

The COgnitive and Physical Exercise to improve Outcomes after Surgery (COPE-iOS) study is a randomised, controlled, participant and assessor blinded clinical trial testing the hypothesis that a pragmatic programme combining CCT and physical exercise throughout the perioperative (ie, preoperative and postoperative) period will improve long-term cognitive and disability outcomes in older surgical patients at high risk for decline. The trial aims to randomise 250 patients who undergo major surgery for a treatment period of approximately 1 month prior to surgery and 3 months after surgery, with a follow-up period of 12 months after surgery. The primary outcome is global cognition at 3 months after surgery. Key secondary outcomes include global cognition at 12 months after surgery and disability in activities of daily living and depression at 3 and 12 months after surgery.

Trial protocol has been approved by Vanderbilt Human Research Protections Programme (#202496) and an independent Data Safety Monitoring Board. Results will be presented at scientific conferences and submitted for publication.

Patients and families from culturally and linguistically diverse (CALD) backgrounds face distinct challenges during end-of-life care (EOLC) in intensive care unit (ICU) settings, where communication, cultural expectations and decision-making may conflict with clinical norms. These complexities have important implications for intensive and palliative care teams.

To map literature on clinician, patient and family perspectives on end-of-life communication with CALD populations in ICUs, and identify barriers and facilitators to culturally responsive care.

This scoping review followed Joanna Briggs Institute methodology and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews checklist. The protocol was registered with the Open Science Framework and published in BMJ Open. Screening, review and data extraction were conducted by multiple reviewers using Covidence and the Joanna Briggs Institute tool, with findings synthesised through inductive thematic analysis.

The primary outcome was to identify barriers and facilitators to communication between clinicians, patients and families from CALD backgrounds during EOLC. Secondary outcomes were to map the scope of evidence, describe study characteristics and participant demographics, and summarise themes on cultural sensitivity, clinician awareness, family involvement, decision-making and integration of support services.

Thirty of 766 screened studies were included. Three themes emerged: communication challenges; cultural sensitivity and humility and decision-making and support. Barriers included limited access to palliative care, language discordance, underuse of interpreters, clinician discomfort and conflicting care expectations. Facilitators included structured meetings, inclusive practices and interdisciplinary collaboration.

Structural, communicative and cultural barriers undermine equitable EOLC for CALD patients. Embedding palliative care principles, cultural responsiveness and shared decision-making into ICU practice requires coordinated input from a multidisciplinary team involving physicians, nurses, social workers, spiritual care, psychologists and interpreters. System-level reforms in training, service delivery and research are needed to ensure person-centred care.

To explore public perceptions of COVID-19 vaccine acceptance and hesitancy in India, and to identify underlying factors influencing attitudes toward vaccination during the second wave of the pandemic.

A cross-sectional qualitative study based on a grounded theory approach.

Community-based interviews conducted in Mumbai, a densely populated metropolitan city in India, during the second COVID-19 wave (April–June 2021).

Twenty purposively selected adults (men and women aged 22–87 years) from varied educational and occupational backgrounds. Inclusion criteria were willingness to participate and the ability to provide informed consent; individuals directly involved in COVID-19 vaccine policy or administration were excluded.

In-depth semi-structured interviews were conducted using an interview guide exploring perceptions of COVID-19 vaccination. Interviews were audio-recorded, transcribed verbatim and analysed inductively following grounded theory principles. Reflexivity was maintained throughout data collection and analysis.

Key emergent themes relating to vaccine acceptance, hesitancy and influencing factors such as safety concerns, efficacy perceptions, media influence and social determinants of vaccine choice.

Attitudes toward vaccination ranged from strong acceptance to hesitancy driven by concerns about safety, side effects and the speed of vaccine development. Media coverage, peer and healthcare professional opinions, and personal experiences shaped the decision of the participants. Cost considerations and lack of vaccine choice influenced uptake. Many participants favoured vaccination being voluntary rather than mandatory for the general population.

Trust in authorities, transparent risk communication and culturally sensitive engagement are critical to improving vaccine confidence. Public health strategies should address safety concerns, ensure equitable access and promote consistent messaging to enhance vaccine acceptance in current and future pandemic contexts.

Interstitial lung diseases (ILD) associated with an underlying connective tissue disease (CTD), also known as a systemic autoimmune rheumatic disease or SARD, are chronic conditions with a tendency to progress. CTD-ILDs are increasingly diagnosed and pose an important global health challenge. This systematic review aims to provide an overarching evaluation of their epidemiology and disease burden in Asia. In this review, the term CTD-ILD will be used to denote all major forms of ILD arising in the context of a SARD.

This systematic review will adhere to the standards of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, including a flow diagram to depict the process by four independent reviewers that will assess titles and abstracts against the following predetermined criteria. A systematic review of the literature search published from 2000 to 2024 will be conducted using five electronic databases including PubMed/MEDLINE, Scopus, EMBASE, Cochrane Library and Web of Science. Publications that meet the inclusion criteria of this review will be subjected to a full-text review to extract relevant data. Collated data will be analysed and organised into categories based on the expected outcome and objectives. The quality of published evidence, including heterogeneity across studies, will be checked against PRISMA checklists and assessed by Newcastle-Ottawa Scale.

Ethics approval is not applicable for this study since no original data will be collected. The findings of this review will be disseminated through a peer-reviewed publication in a scientific journal and conference communications, with the aim of contributing insights to the field by identifying research gaps and informing clinical practice.

The protocol of this systematic review is registered with the National Medical & Research Register (ID-24–03600-GUB) and International Prospective Register of Systematic Reviews PROSPERO (CRD420251037095).

To assess the feasibility and preliminary effectiveness of ‘Partners for Patient Safety’ (P4PS) programme for strengthening competencies and patient engagement at the organisational level.

Prospective study with three measurement points (baseline, interim and follow-up) and an explanatory sequential mixed methods approach for formative and process evaluation.

Oncology-focused patient and family advisory councils (PFACs) integrated into healthcare organisations and networks in five German federal states.

Initially, 36 stakeholders of six PFACs were recruited. At follow-up, 27 participated in all intervention modules and completed all surveys. From those, 14 participated in follow-up interviews.

The P4PS programme consists of two sequentially implemented modules: (1) an e-learning module and (2) a 4-hour on-site workshop. The programme focuses on the following topics: patient safety (PS), communication strategies and PFAC engagement in respective care organisations.

Primary outcome measures were feasibility domains, assessed via standardised (acceptability, appropriateness, feasibility) and self-developed measures (relevance, acceptability and social validity, complexity and practicability, demand and implementation, and adaptability). Secondary outcome measure was preliminary effectiveness, measured via changes in self-assessed competencies in PS, communication and engagement.

Feasibility ratings were high across standardised and self-developed measures (median range: 4–5 of 5). Qualitative data showed P4PS programme’s practical relevance, need for organisational support and its adaptability across PFAC contexts. Effectiveness analyses showed significant improvements in PS competencies (adjusted pV) and selected domains of PFAC engagement (adjusted pd=–0.77 to –1.37). Participants expressed strong expectations for future improvements in competencies regarding PS, communication and PFAC engagement.

This P4PS programme showed high feasibility and effectiveness, it increased key competencies, clarified roles and promoted active PFAC engagement in PS. Future work needs to address organisational support and sustainable implementation with application to context as well as long-term evaluation across different care settings.

To identify enablers and barriers for scaling up non-communicable disease (NCD) interventions across diverse global contexts and to map these factors to the WHO’s health system building blocks.

A multi-method qualitative study applying the Consolidated Framework for Implementation Research to analyse data from multiple projects nearing or completing scale-up.

Global Alliance for Chronic Diseases-funded implementation research projects conducted across 18 low- and middle-income countries and high-income settings.

Data was derived from documents (n=77) including peer-reviewed publications, policy briefs, and reports and interviews with stakeholders (n=18) (eg, principal investigators, medical professionals, public health workers).

Various context-specific interventions targeting sustainable scale-up of NCD (eg, diabetes, hypertension, cardiovascular disease) interventions at the community, primary care or policy levels.

The primary outcome was identifying contextual enablers and barriers to intervention scale-up. Secondary outcomes included exploring how these factors aligned with health system building blocks (eg, leadership/governance, healthcare workforce).

Twenty enablers (eg, intervention adaptability, strong stakeholder engagement, local empowerment) and 25 barriers (eg, resource limitations, intervention complexity, stakeholder burnout) were identified. Contextual alignment, supportive governance and capacity building were critical for sustainability, while cultural misalignment and socio-political instability frequently hampered scaling efforts.

Tailoring interventions to local health systems, ensuring stakeholder co-ownership and incorporating strategies to mitigate stakeholder burn-out are essential to achieving sustainable, scalable NCD solutions. Future research should focus on integrating systematic cultural adaptation, sustainable financing and workforce capacity building into scale-up planning.

Process evaluation provides insight into how interventions are delivered across varying contexts and why interventions work in some contexts and not in others. This manuscript outlines the protocol for a process evaluation embedded in a hybrid type 1 effectiveness-implementation randomised clinical trial of incremental-start haemodialysis (HD) versus conventional HD delivered to patients starting chronic dialysis (the TwoPlus Study). The trial will simultaneously assess the effectiveness of incremental-start HD in real-world settings and the implementation strategies needed to successfully integrate this intervention into routine practice. This manuscript describes the rationale and methods used to capture how incremental-start HD is implemented across settings and the factors influencing its implementation success or failure within this trial.

We will use the Consolidated Framework for Implementation Research (CFIR) and the Reach, Effectiveness, Adoption, Implementation and Maintenance (RE-AIM) frameworks to inform process evaluation. Mixed methods include surveys conducted with treating providers (physicians) and dialysis personnel (nurses and dialysis administrators); semi-structured interviews with patient participants, caregivers of patient participants, treating providers (physicians and advanced practice practitioners), dialysis personnel (nurses, dieticians and social workers); and focus group meetings with study investigators and stakeholder partners. Data will be collected on the following implementation determinants: (a) organisational readiness to change, intervention acceptability and appropriateness; (b) inner setting characteristics underlying barriers and facilitators to the adoption of HD intervention at the enrollment centres; (c) external factors that mediate implementation; (d) adoption; (e) reach; (f) fidelity, to assess adherence to serial timed urine collection and HD treatment schedule; and (g) sustainability, to assess barriers and facilitators to maintaining intervention. Qualitative and quantitative data will be analysed iteratively and triangulated following a convergent parallel and pragmatic approach. Mixed methods analysis will use qualitative data to lend insight to quantitative findings. Process evaluation is important to understand factors influencing trial outcomes and identify potential contextual barriers and facilitators for the potential implementation of incremental-start HD into usual workflows in varied outpatient dialysis clinics and clinical practices. The process evaluation will help interpret and contextualise the trial clinical outcomes’ findings.

Hospital patients are at an increased risk of falls, which are a significant safety concern within healthcare settings.¹ Understanding how the COVID-19 pandemic has influenced fall risks is essential for identifying key factors that could inform future fall prevention strategies.² This scoping review aims to explore the barriers and challenges associated with preventing inpatient falls in the context of the post-COVID-19 environment.

The methodology for this scoping review follows the framework established by Arksey and O’Malley. A comprehensive literature search will be conducted using specific keywords to identify relevant published studies. Searches will be performed across selected electronic databases, including PubMed/MEDLINE, CINAHL, Scopus, ProQuest and Web of Science, covering publications from 2014 to 2024. This review will focus on a global perspective. Two authors will independently screen titles and abstracts to identify potential studies for inclusion. Studies meeting the inclusion criteria will be retrieved for full-text review, and their references will be assessed for relevance using the same criteria. The PRISMA flow diagram will guide the review process. Data will be extracted, analysed and charted according to categories from the selected publications.

This scoping review will provide a comprehensive overview of the barriers and challenges in preventing inpatient falls in the post-pandemic context. The findings will be disseminated through submission for publication in a scientific journal.

On 1 January 2023, Ontario expanded pharmacists’ scope of practice, allowing them to prescribe medications for 13 minor ailments, including antibiotics for uncomplicated urinary tract infections (UTIs) and Lyme disease (LD) prophylaxis. This study evaluates pharmacist billing claims and pharmacist and physician antibiotic-prescribing rates before and after policy implementation.

An interrupted time series analysis measuring changes in prescribing trends post-implementation.

This retrospective study analysed visit claims and antibiotic prescribing for UTIs and LD prophylaxis before policy implementation (2022) and after (2023–2024) in Ontario.

Data from Ontarians

Prescribing rates were standardised per 1000 inhabitants, stratified by provider type, patient age and sex, and antibiotic type.

In 2023 and 2024, pharmacists submitted over 1.47 million minor ailment claims, with UTIs making up 34.2% and LD prophylaxis making up 2.6% of total claims. UTI claims were primarily for women aged 25–64, and LD prophylaxis peaked in spring and fall. Pharmacist prescribing of eligible urinary drugs in females increased by 33.3 per 1000 person-years (95% CI 30.8 to 36.6) while physician prescribing decreased by 23.3 (95% CI –32.2 to –15.3), leading to a modest net increase of 10.1 (95% CI 0.0 to 18.7). Pharmacist prescribing of doxycycline was offset by decreased physician prescribing, resulting in no change (0.0, 95% CI –1.0 to 0.9). Pharmacist prescribing for other antibiotics was low over the study timeframe, while physician prescribing increased, which was driven by increased prescribing of penicillins and macrolides.

There was a clear increase in pharmacist prescribing for eligible drugs in the eligible population post-policy implementation. Pharmacists in Ontario appear to be prescribing within policy limits for uncomplicated UTIs and LD prophylaxis.

Falls are highly prevalent among individuals with dementia, largely due to the cognitive and physical impairments associated with the condition. Understanding the barriers and challenges to fall prevention in community-dwelling individuals with dementia is essential for developing tailored strategies that address their unique risks. Despite the existing evidence on fall prevention in older adults, few reviews specifically examine the obstacles faced by persons with dementia and their caregivers in community settings. This scoping review, therefore, aims to map the barriers and challenges to preventing falls among community-dwelling individuals with dementia.

This review will follow Arksey and O’Malley’s five-stage framework and be reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses—Extension for Scoping Reviews checklist. Six electronic databases (PsycINFO, PubMed, Web of Science, Cumulative Index to Nursing and Allied Health Literature, Scopus and Embase) will be searched for relevant studies published between 2014 and 2024. Grey literature sources, including dissertations and conference proceedings, will also be included. Data will be charted and synthesised thematically to provide an overview of barriers and contextual factors influencing fall prevention. The study commenced in August 2025 and is expected to be completed by February 2026.

As this review involves the analysis of existing literature, ethical approval is not required. Findings will be disseminated through peer-reviewed publications, conference presentations and summaries tailored for healthcare providers and caregiver groups.

Retinal neurodegeneration has recently been shown to occur in tandem with neurodegenerative disease. In the expectation that disease-modifying treatments for Alzheimer’s disease (AD) and Parkinson’s disease (PD) will soon become available, it will be important to have clinically useful biomarkers for neurodegenerative disease subtyping to guide early diagnosis, inform on prognosis and stratify subgroups for treatment. Understanding differences in detectable retina changes in individuals with different neurodegenerative disease subtypes is therefore fundamental. The emerging field of oculomics posits that systemic and neurodegenerative disease can be characterised using detectable ocular biomarkers within retinal diagnostics. The aim of this review is to compare the performance of common retinal imaging modalities in neurodegenerative disease detection and subtyping.

This protocol has been reported in accordance with the PRISMA-P (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols) guidelines. A comprehensive literature search will be conducted in PubMed, Web of Science and Scopus. Eligible studies will have reported using retinal diagnostic tools defined as optical coherence tomography (OCT), OCT angiography (OCTA), colour fundus photography (CFP) and electroretinography (ERG) in individuals with neurodegenerative diseases, including AD, PD, dementia with Lewy bodies, frontotemporal dementia, vascular dementia and mild cognitive impairment. There will be no time restrictions placed in these searches. Studies not written in English, not peer-reviewed and grey literature will be excluded. Screening for eligible studies and data extraction will be conducted by two independent reviewers, using predefined inclusion criteria. Any disagreements between the reviewers will be settled by discussion, and if required, third senior reviewer arbitration. The systematic review primary outcome is the performance of retinal diagnostics, namely OCT, OCTA, CFP and ERG in the detection and subtyping of aforementioned neurodegenerative diseases. The secondary outcome is to evaluate the association between changes in retinal diagnostic features (eg, retinal layer thicknesses) and neurodegenerative disease subtypes. The quality of the included studies will be assessed using the GRADE (Grading of Recommendations Assessment, Development and Evaluations) tool. A narrative synthesis approach will be used to analyse the results, with meta-analysis performed if there is sufficient data.

Ethical approval for this manuscript is not required, as this is a protocol for a systematic review and therefore no data are to be collected. Findings for this systematic review will be disseminated as a peer-reviewed publication and presentations at national and international symposiums including International Lewy Body Dementia Conference, International Congress of Parkinson’s Disease and Movement Disorders, The Association for Research in Vision and Ophthalmology.

Oral health research provides evidence for policy and practice, yet no study has comprehensively mapped the scope of oral health research in Malaysia. The COVID-19 pandemic has also created a great impact on oral healthcare in Malaysia, including the dental care delivery. Additionally, there is a notable lack of research focusing on oral health during and after the COVID-19 pandemic. Therefore, this scoping review will aim to map the landscape of oral health research conducted in Malaysia and identify key topics, study designs, populations studied and gaps in the literature, in order to inform future research priorities and policy, particularly in the post-COVID-19 era.

The methodology draws on Arksey and O’Malleys’ seminal framework for the scoping review and will be reported in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Review (PRISMA-ScR) guidelines. We will search five major electronic databases—PubMed, Scopus, ProQuest, Cochrane and Web of Science—as well as selected grey literature sources (eg, theses, dissertations and conference proceedings) for studies published in English from January 2014 to December 2024. Studies of any design related to oral health in Malaysia will be included. Two reviewers will be performing title and abstract screening, in which they will be working independently. The included publication will undergo a full-text review, and references cited in these studies will be examined following the inclusion criteria. The PRISMA-ScR flow diagram will be used as a guide throughout the process. Data will be extracted, analysed and charted according to key categories identified in the included publications. A narrative synthesis and descriptive statistics will be presented.

The results of this scoping review will illustrate an overview and provide a better understanding regarding the oral health research in the Malaysian context; whether research has already been conducted, is currently ongoing and is still needed; and which areas should be prioritised for future investigation. As this review will use publicly available literature, formal ethics approval will not be required. The findings will be submitted for publication in an open-access peer-reviewed journal, presented at national and regional conferences and shared with Malaysian dental professional bodies and relevant stakeholders.

The protocol of this scoping review is registered with the Open Science Framework and is available at osf.io/hjq6m.

Improving outcomes from sepsis in children is a WHO Global Health Priority, yet mortality from sepsis remains high, particularly in low- and middle-income countries (LMICs). This database from children with community-acquired childhood sepsis in LMICs and some high-income countries will allow analysis of the burden of disease, including incidence, severity and outcomes. Understanding these aspects of sepsis care is fundamental for the design and conduct of future international interventional trials to improve childhood sepsis outcomes.

This multicountry retrospective observational study will include children up to 18 years of age presenting to emergency departments with suspected sepsis, defined as admission to hospital for treatment with intravenous antibiotics plus (1) a provisional diagnosis of sepsis and/or (2) treatment for suspected sepsis (operationalised as the administration of one or more fluid bolus to treat impaired perfusion or vasoactive infusion). Presenting characteristics, management and outcomes will be collected. These will include vital signs, serum biomarkers, intravenous fluid administration for the first 24 hours of hospitalisation, organ support therapies delivered, antimicrobial use, microbiological diagnoses, hospital and intensive care unit length of stay, and mortality censored at hospital discharge or 30 days from enrolment (whichever occurs first).

Central ethics approval was received from the Royal Children’s Hospital of Melbourne, Australia Human Research Ethics Committee (HREC/100648/RCHM-2023). Each international site will be required to obtain local Institutional Research Ethics Board approval. The findings will be disseminated in peer-reviewed journals, at academic conferences and through lay media. A cleaned study database and individual site-level data will be made available to site investigators upon completion of the study.

This study was registered with the Australian and New Zealand Clinical Trials Registry on 23 January 2024 prior to commencement of recruitment (ACTRN12624000052538).

Tobacco use accounts for approximately 1.35 million deaths annually in India, disproportionately affecting low-income individuals, men, rural residents, those without formal education and groups of low socioeconomic status (SES). Despite progress in tobacco control, scalable, low-cost solutions, such as brief advice interventions, are needed. This study explored priority implementation determinants for adapting an evidence-based brief advice/counselling intervention for high-reach, low-resource settings in Mumbai, India. The focal settings (health-focused and tuberculosis-focused non-governmental organisations (Health NGOs and TB NGOs) and dental clinics) served low-SES populations.

Mumbai-based and US-based team members conducted a qualitative study employing semistructured interviews to gather data from four groups connected to Health and TB NGOs and dental clinics: (1) 15 patients, (2) 33 practitioners, (3) nine practice leaders and (4) three policymakers. We used a team-based, critical, reflexive thematic analysis approach to analysis, grounded in the Exploration, Preparation, Implementation and Sustainment framework. We managed data with Nvivo software.

Participants were supportive but highlighted diverse challenges and supports required for implementing the intervention in these diverse settings. First, many noted that societal constraints such as economic insecurity and cultural factors were expected to limit tobacco control efforts for low-SES populations. Second, setting-specific intervention adaptations were identified as necessary to support integration and ensure access to support for all patients. Various participant groups highlighted different adaptation areas. For example, patients noted that tobacco was part of their routines and social lives, practitioners emphasised the need to design implementation plans that support integration alongside existing needs, and policymakers highlighted the need for uniform implementation strategies.

Adapting brief advice/counselling interventions for Health NGOs, TB NGOs and dental clinics in Mumbai will require strategic communication to support buy-in, thoughtful workflow integration and changes to funding and support mechanisms for organisations so meaningful reductions in tobacco use can be achieved among low-SES groups. In other words, there is a need to adapt both the intervention and the implementing system to allow for brief advice/counselling to contribute to broader tobacco control efforts.
