Applications of artificial intelligence for real-world evidence generation: a protocol for a living scoping review

Por: Oikonomidi · T. · Raad · H. · Diaz-Decaro · J. · Li · H. · Y Smith · M. · Rivera · D. R. · Liu · W. · Soriano Gabarro · M. · Bennett · D. · Mack · C. D. · Teltsch · D. Y. · Gerber · J. E. · Bray · B. · Dickinson · H. · Jani · M. · Naidoo · N.
Introduction

Artificial intelligence (AI) is rapidly evolving, offering an expanding suite of capabilities that go beyond the traditional focus on prediction and classification. Generative AI (GenAI) and agentic AI could create transformative practices to support real-world evidence (RWE) generation for health research by streamlining studies, accelerating insights and improving decision-making. However, there is no published overview available describing the range of applications in RWE generation. This review aims to describe where and how genAI and agentic AI are applied across the domains of healthcare research tasks for RWE generation. Additionally, to map applications by tasks and methods across the product lifecycle continuum, and to identify emerging gaps and opportunities.

Methods and analysis

This Living Scoping Review (LSR) will include studies reporting an application and/or evaluation of genAI or agentic AI applied to one or more RWE generation research tasks. Searches will be conducted in Embase, MEDLINE and additional sources (eg, grey literature). Citations will be independently screened by two human senior reviewers for a substantive training dataset and a commercially available screening algorithm (Robot Screener) will complete screening with a human reviewer. The LSR will include reports of studies (primary or reviews) describing and/or evaluating the application of any genAI model for RWE generation in healthcare, in English, published from 1 January 2025 to the date of search. Data will be extracted from all studies included in the LSR by one independent senior reviewer using a piloted template, with 10% quality check by a second senior reviewer. Descriptive statistics will be used to summarise the applications of genAI per RWE research task, and the results of genAI evaluations. Thematic analysis will be used to describe genAI application patterns, trends, gaps and opportunities. The LSR protocol and reports will be updated annually, and findings will be published on a publicly available website (eg, ISPE—the International Society for Pharmacoepidemiology).

Objective

This study investigated perinatal depressive symptoms among pregnant and postpartum Filipino women.

Design

Cross-sectional survey.

Setting

The Philippines.

Participants

Participants were recruited online and face-to-face from maternal care facilities.

Primary outcome measure

Perinatal depressive symptoms were assessed using the Edinburgh Postnatal Depression Scale (EPDS) score, with prevalence calculated based on ≥13 cut-off, indicating clinically significant symptoms of depression. Patterns of depressive symptoms were examined by demographics, perinatal time period and other obstetric information using adjusted regression coefficients (ab) and risk ratios (aRR).

Results

A total of 856 women participated in the study, comprising 356 pregnant and 500 postpartum women. EPDS scores were, on average, similar between pregnant (14.4) and postpartum women (14.1). Using the locally validated cut-off of ≥13 revealed that 69.1% of pregnant and 62.0% of postpartum women reported clinically significant depressive symptoms. Consistent EPDS scores and prevalence were observed across pregnancy trimesters and within 12 months postpartum and beyond. Women who received adequate prenatal care were less likely to experience antenatal (ab=–1.59, 95% CI –3.13 to –0.05) and postpartum (ab=–1.30, 95% CI –2.48 to –0.12) depressive symptoms. Postpartum EPDS scores and depressive symptom prevalence (EPDS score ≥13) were higher among 18–24-year olds (ab=1.96, 95% CI 0.30 to 3.61; aRR=1.23, 95% CI 1.03 to 1.47) and single mothers (ab=3.46, 95% CI 0.22 to 6.71; aRR=1.42, 95% CI 1.07 to 1.90), compared with older and married mothers, respectively.

Conclusions

At least 60% Filipino mothers experienced clinically significant perinatal depressive symptoms, which exceeds the established global average of 25%. Younger and single postpartum women were at greater risk, while pregnant and postpartum women who attended adequate prenatal visits were less likely to report depressive symptoms. Our study underscores the need for further research to uncover the true burden of poor perinatal mental health and calls for targeted early interventions and integrative public health strategies to support at-risk mothers, particularly those from socially disadvantaged backgrounds.

Economic information in clinical decision-making: focus group discussions with Finnish general practitioners and patients

Por: Ahonen · J. E. · Sipilä · R. · Kortteisto · T. · Komulainen · J.
Objectives

To study the factors that influence physicians’ and patients’ use of, and willingness to use, economic information in clinical decision-making, and examine physicians’ views on whether clinical practice guidelines can support its use.

Design

Semistructured focus group discussions with an inductive content analysis.

Setting

Finnish health centre general practitioners (GPs) and adult patient representatives, five groups of each.

Participants

22 GPs and 15 patient representatives.

Results

In the GP groups, five factors involved in using economic information in clinical decisions were raised: the issue of who pays, knowledge about cost information, the cost-benefit ratio of treatments, care planning and health economic understanding. Concerning the inclusion of economic information in clinical guidelines, GPs raised themes including the content and means of presentation of economic information, and advantages and challenges related to the integration of economic information into clinical guidelines. In the patient groups, the identified themes related to seeing the costs of treatments, the organisation of healthcare services, inclusion of cost information in clinical guidelines, patient information and support, and cost containment in healthcare.

Conclusions

The study suggests that GPs and patients are willing to use economic information in clinical decision making. It also implies a need for easily accessible and understandable economic information, and that clinical guidelines may be a good way to support this. In addition, the study highlights the need for education on the economic aspects of healthcare for physicians.

Assessing the impact of automated devices for enhancing health and reducing medication errors in older adults with long-term health conditions (ADHERE): a study protocol for a randomised controlled trial in Bedfordshire, Luton and Milton Keynes, UK

Por: Wainwright · J. E. · Bennett · A. · Randhawa · G. · Pappas · Y. · Singh · H. · Cook · E. J.
Introduction

Medication non-adherence in older adults with long-term conditions contributes to significant morbidity, mortality and healthcare costs. While adherence support tools exist, many interventions fail to reach those most at risk. Automated medication dispensers (AMDs) show promise in improving adherence and health outcomes, but their integration into routine community pharmacy practice remains underexplored. This study aims to assess the effectiveness of an AMD intervention with SMS reminders in enhancing medication adherence among older adults and to evaluate how this technology can be integrated into community pharmacy workflows.

Methods and analysis

This randomised controlled trial involves 144 participants recruited from eight community pharmacies who will be randomised to receive either the AMD intervention or usual care. Primary outcomes include medication adherence, measured through pharmacy records and self-report at baseline, 3 and 6 months. Secondary outcomes include Morisky Medication Adherence Scale, health-related quality of life (SF-12), and healthcare resource use. A nested mixed methods process evaluation will explore uptake, acceptability and implementation.

Ethics and dissemination

The study protocol has been approved by the University of Bedfordshire Institute for Health Research Ethics Committee (IHREC1039), the NHS and the local authority Research Governance and Research Ethics Committee (NHS REC reference: 25/EE/0026). The findings will be disseminated via a final report, peer-reviewed journal publications and presentations at relevant conferences.

Impact of a booster intervention of the 'More Time at Patients Side programme on patients and healthcare professionals in a Swiss hospital: protocol for a cluster randomised controlled trial

Por: Buclin · C. P. · Bürgisser · N. · Mongin · D. · Le Mauguen · A. · Farhoumand · P. D. · Berner · A. · Daverio · J. E. · Barrios · J. · Reny · J.-L. · Courvoisier · D. S. · Agoritsas · T.
Introduction

Healthcare professionals are increasingly burdened by clerical tasks, contributing to reduced job satisfaction, heightened burnout and potential risk for patient safety. Despite ongoing efforts to promote patient-centred care, direct interaction time with patients remains limited, affecting both professional fulfillment and the quality of patient experience. In response, hospitals have begun implementing structured programmes to enhance protected patient time, though their effectiveness remains uncertain. The Geneva University Hospitals (HUG) developed the ‘More Time at Patients’ Side’ (MTP) programme, integrating Lean management and Design Thinking principles to optimise clinical interactions. This study aims to evaluate an MTP booster intervention, designed to reinforce selected programme elements, using a cluster-randomised controlled trial focusing on patient pain management and healthcare professional job satisfaction.

Methods and analysis

The MTP Booster will be implemented in selected units at HUG across internal medicine, surgery, rehabilitation, palliative care and paediatrics units. Originally launched in 2017, the MTP programme introduced structured medical rounds, delegated clerical tasks and communication tools such as patient whiteboards. The booster intervention follows a stepped-wedge cluster-randomised design, with immediate reactivation in intervention units and delayed implementation in control units. The intervention consists of two key components: (A) a collaborative selection of MTP elements to reinforce, based on their feasibility and perceived usefulness and (B) structured integration of audit and feedback into daily routines, including on-site observations and staff training. The primary outcome is the quality of pain management, measured by the timely administration of analgesia. Secondary outcomes include pain documentation, patient satisfaction, healthcare professional work satisfaction, burnout levels, turnover risk and absenteeism. Other MTP-related audits are suspended during the study to preserve methodological integrity, and concurrent institutional initiatives will be documented as potential confounders.

Ethics and dissemination

The trial has a declaration of no objection by Swissethics (2024-00169). All final results will be reported in accordance with the Consolidated Standards of Reporting Trials extended for cluster-randomised trials. We intend to publish the results of this trial in an international peer-reviewed journal, irrespective of the results.

Trial registration number

The trial is currently in the pre-results stage and is registered at ClinicalTrials.gov, ID: NCT06491797, 9 July 2024.

Comparison of Surgery and Medicine on the Impact of Diverticulitis (COSMID) trial: a protocol for a pragmatic randomised study of diverticulitis treatment in the USA

Por: Hantouli · M. N. · Schmicker · R. H. · Tufte · J. E. · Ali · F. G. · Bennett · R. D. · Cohan · J. N. · Comstock · B. A. · Curran · T. · Davidson · G. H. · Eisenstein · S. · Fischkoff · K. N. · Fleming · F. J. · Gribovskaja-Rupp · I. · Jafari · M. D. · Kessler · L. G. · Krane · M. K.
Introduction

Each year, millions of people experience recurrent diverticulitis episodes. Elective sigmoid colon resection reduces the risk of recurrence, but The American Society of Colon and Rectal Surgeons recommends individualising surgical decisions based on the impact of the condition on a patient’s quality of life (QoL). However, no threshold for QoL impairment has been established to guide decision-making, and evidence comparing elective colectomy with medical management in terms of QoL limitation is limited. To address these gaps and to guide treatment decision-making, we designed the Comparison of Surgery and Medicine on the Impact of Diverticulitis (COSMID) trial.

The COSMID trial is a large, pragmatic randomised trial including patients with QoL-limiting diverticulitis that aims to determine if partial colectomy is superior to medical management and explore subgroups that are more likely to respond to each treatment.

Methods and analysis

COSMID will recruit 250 English-speaking and Spanish-speaking adults with imaging-confirmed and QoL-limiting diverticulitis (defined using a modified diverticulitis-related QoL survey). Participants are randomly assigned to undergo elective partial colectomy or receive comprehensive medical management (eg, selected from options including fibre, probiotics, mesalamine and rifaximin). A total of 100 patients who decline randomisation but consent to follow-up will be included in a parallel observational cohort. The primary outcome is the time-averaged score of the Gastrointestinal Quality of Life Index at 6, 9 and 12 months after randomisation. Secondary outcomes include clinical adverse events, healthcare utilisation, recurrent episodes of diverticulitis and additional patient-reported outcomes like the Diverticulitis Quality of Life instrument, decisional regret and work productivity. Exploratory analyses aim to identify differential treatment effects based on patients’ characteristics.

Por: Lin · T. · Cohen · Z. D. · Stefan · S. · Soflau · R. · Fodor · L. A. · Georgescu · R. · Bruijniks · S. J. E. · Lemmens · L. · Bagby · M. · Quilty · L. · Ekeblad · A. · Holmqvist · R. · Evans · J. · OMahen · H. A. · Johnson · J. E. · Zlotnick · C. · Hilpert · P. · Carter · J. · McBride · C.
Introduction

Cognitive behavioural therapy (CBT) and interpersonal psychotherapy (IPT) are both efficacious treatments for depression, but it is less clear how both compare on outcome domains other than depression and in the longer term. Moreover, it is unclear which of these two psychotherapies works better for whom. This article describes the protocol for a systematic review and individual participant data (IPD) meta-analysis that aims to compare the efficacy of CBT and IPT for adults with depression on a range of outcomes in both the short and long term, and to explore moderators of the treatment effect. This study can enhance our understanding of treatments for depression and inform treatment personalisation.

Methods and analysis

Systematic literature searches will be conducted in PubMed, PsycINFO, EMBASE and the Cochrane Library from inception to 1 January 2026, to identify randomised clinical trials (RCTs) comparing CBT and IPT for adult depression. Researchers of eligible studies will be invited to contribute their participant-level data. One-stage IPD meta-analyses will be conducted with mixed-effects models to examine (a) treatment efficacy on all outcome measures that are assessed at post-treatment or follow-up in at least two studies, and (b) various baseline participant characteristics as potential moderators of depressive symptom level at treatment completion.

Ethics and dissemination

Ethical approval is not required for this study since it will be based on anonymised data from RCTs that have already been completed. The findings of the present study will be disseminated through a peer-reviewed journal or conference presentation.

Study protocol for a multi-site case study evaluation of a Canadian quality improvement collaborative to improve Baby-Friendly practices in community health services

Introduction

In Canada, many families want to breastfeed, but there are several common challenges they may encounter. Currently, 91% of Canadian families initiate breastfeeding after giving birth, yet only 38% of babies are breastfed exclusively to 6 months. In 1991, the Breastfeeding Committee for Canada (BCC) was established to implement the World Health Organization’s Ten-Step Baby-Friendly Hospital Initiative, a series of evidence-based in-hospital practices to support families to breastfeed. Then, in recognition of the need to support breastfeeding beyond the hospital setting, the BCC expanded the Baby-Friendly Initiative (BFI) to apply the Ten Steps to both hospitals and community health settings. However, uptake of the BFI Ten Steps in community settings has been low and methodology on how to optimise implementation of the Ten Steps in community is not well developed. Therefore, the objective of this project is to develop and evaluate a quality improvement collaborative with 25 community health services from across Canada to learn how to best support the implementation of the BFI Ten Steps in community, with the ultimate goal of improving breastfeeding outcomes.

Methods and analysis

This protocol describes the activities of the Community Baby-Friendly Initiative Collaborative (CBFI-C) and the methods used to evaluate its effectiveness. We will use the Institute for Healthcare Information Breakthrough Series (IHI-BTS) model, a proven quality improvement model that has been widely used in clinical settings, but is not yet widely used in community settings. The IHI-BTS combines three virtual learning sessions with action cycles that allow the participating sites time to test and track small practice changes. Sites will be asked to track care indicator and breastfeeding outcome data, engage in monthly webinars, receive coaching from trained mentors, participate in focus groups and participate in a final summative workshop. We will use a multi-site case study approach, combining aggregate care indicator data and qualitative data from webinars, focus groups and workshops to evaluate how the CBFI-C model supports community sites in the process of implementing the BFI Ten Steps.

Ethics and dissemination

Ethics approval for this evaluation was obtained from the CHIPER Health Research Ethics Board (Number HS26947-H2025:157)). The results of the CBFI-C evaluation will be shared in a report, peer-reviewed publications and presentations to government and academic audiences. The findings will inform effective quality improvement strategies to enhance uptake of the BFI in community health settings.

Preferences and predictors driving opioid-involved polysubstance use profiles and trajectories: a prospective cohort study protocol

Por: Campbell · M. · Lafayette · J. I. · Vallejo Vasquez · K. · Rivard · A. · Diamond · J. · Nguyen · C. · Caputo · D. · Lothumalla · S. · Rodriguez · C. R. · Tomlinson · D. C. · Bonar · E. E. · Goldstick · J. E. · Walton · M. · Lee · S. · Menke · N. · Lin · L. · Coughlin · L. N.
Introduction

Polysubstance use (PSU), particularly opioid-involved and stimulant-involved PSU, is a growing issue in the USA. PSU increases the risk of negative health consequences, including infectious diseases, worsening physical and mental health conditions, and overdose-related deaths. These consequences occur in the context of varying health risk behaviours, substance-related preferences, and treatment engagements among people with PSU. To inform improvements in prevention, harm reduction, and substance use disorder (SUD) treatment, additional research is needed to comprehensively understand the current context and drivers of PSU preferences, motivations, and behaviours.

Methods and analysis

Herein, we describe the protocol for a prospective cohort study designed to capture detailed patterns, profiles, and trajectories of PSU, with the aim of comprehensively examining the drivers of PSU behaviours and SUD treatment utilisation. Adults (ages 18–75; n=400) who engage in PSU will be recruited from healthcare institutions, an established participant database maintained by an adjacent SUD research team, and online advertisements. Study assessments will capture dynamic patterns, choice preferences, and motivators of PSU via behavioural economic (BE) measures, detailed Timeline Follow-Back (TLFB) interviews, and self-administered surveys. The assessment timeline will include a baseline survey and TLFB interview, weekly TLFB interviews for 4 weeks post-baseline, and follow-up surveys and TLFB interviews at 4-, 8-, and 12-months post-baseline.

Ethics and dissemination

The study is funded through the National Institutes of Health Helping to End Addiction Long-term (HEAL) initiative and was approved by the University of Michigan Medical Institutional Review Board. Findings will be disseminated to academic, clinical, and community partners through the Michigan Innovations in Addiction Care through Research and Education programme. Results from this study will inform actionable and practical insights relevant to the delivery of personalised care in the context of PSU.

Objectives

There are little available data on the prevalence, economic and quality of life impacts of musculoskeletal disorders in sub-Saharan Africa. This lack of evidence is wholly disproportionate to the significant disability burden of musculoskeletal disorders as reported in high-income countries. Our research aimed to undertake an adequately powered study to identify, measure and value the health impact of musculoskeletal conditions in the Kilimanjaro region, Tanzania.

Design

A community-based cross-sectional survey was undertaken between January 2021 and September 2021. A two-stage cluster sampling with replacement and probability proportional to size was used to select a representative sample of the population.

Setting

The survey was conducted in 15 villages in the Hai District, Kilimanjaro region, Tanzania.

Participants

Economic and health-related quality of life (HRQOL) questionnaires were administered to a sample of residents (aged over 5 years old) in selected households (N=1050). There were a total of 594 respondents, of whom 153 had a confirmed musculoskeletal disorder and 441 matched controls. Almost three-quarters of those identified as having a musculoskeletal disorder were female and had an average age of 66 years.

Primary and secondary outcome measures

Questions on healthcare resource use, expenditure and quality of life were administered to all participants, with additional more detailed economic and quality of life questions administered to those who screened positive, indicating probable arthritis.

Results

There is a statistically significant reduction in HRQOL, on average 25% from a utility score of 0.862 (0.837, 0.886) to 0.636 (0.580, 0.692) for those identified as having a musculoskeletal disorder compared with those without. The attributes ‘pain’ and ‘discomfort’ were the major contributors to this reduction in HRQOL.

Conclusions

This research has revealed a significant impact of musculoskeletal conditions on HRQOL in the Hai district in Tanzania. The evidence will be used to guide clinical health practices, interventions design, service provisions and health promotion and awareness activities at institutional, regional and national levels.

The Associations Between Nurses' Perceived Adequacy of Staffing and Quality of Nursing Care and Job Enjoyment: A Multilevel Modelling Approach

ABSTRACT

Aim

To explore the associations of (1) shift-to-shift Nurse Perceived Adequacy of Staffing Scale (NPASS) scores and (2) the relative contribution of individual NPASS items to nurse-perceived quality of care (NPQoC) and job enjoyment.

Design

Multihospital prospective observational study.

Methods

The study was conducted across 15 medical, surgical or acute admission hospital wards in three teaching hospitals in the Netherlands. Vocationally and bachelor-trained nurses conducted 1550 measurements of perceived adequacy of staffing using the NPASS, NPQoC and job enjoyment in 797 shifts. Multilevel models were used to assess associations between NPASS scores and NPASS items and the outcome variables.

Results

Higher NPASS scores were significantly associated with improved NPQoC and job enjoyment. An increase in 1.0 point NPASS score leads to an increase of 0.97 points in NPQoC and 1.04 points in job enjoyment. Of the NPASS items, energy level, adherence to protocols and the opportunity for adequate breaks had the most positive effect on both outcomes.

Conclusion

Perceived adequacy of staffing as measured by the NPASS is highly relevant for improvements in both NPQoC and job enjoyment.

Implications for the Profession and/or Patient Care

Decision-makers on nurse staffing should incorporate the NPASS in staffing methods to ensure adequate staffing and the associated benefits. Policies that ensure adequate breaks, adherence to protocols and maintenance of nurses' energy levels during the shift should be implemented with special attention.

Impact

This study provides supportive evidence for incorporating nurses' perceived adequacy of staffing, as measured by the NPASS, to ensure adequate staffing. This is crucial for nurse retention, and therefore vital to maintaining accessible healthcare given the global nursing shortages.

Reporting Method

The STROBE checklist was used to conduct and describe the study.

Patient or Public Contribution

This study did not include patient or public involvement in its design, conduct or reporting.

Protocol for the process evaluation of a randomised clinical trial of incremental-start versus conventional haemodialysis: the TwoPlus study

Introduction

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.

Methods and analysis

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.

Ethics and dissemination

The study protocol was approved by the Wake Forest University School of Medicine Institutional Review Board (IRB). Findings from this study will be disseminated through peer-reviewed journals and scientific conferences.

COVID-19 antibody testing study: a nested substudy within Albertas Tomorrow Project (ATP) in Alberta, Canada

Por: Nejatinamini · S. · Charlton · C. · Harman · S. · Kanji · J. N. · Kellner · J. D. · Lines · K. · Murdoch · K. · Powell · W. · Roberts · J. · Rosner · W. · Shen-Tu · G. · Tipples · G. · Xu · J.-Y. · Vena · J. E.
Purpose

The Alberta’s Tomorrow Project (ATP) prospective cohort study was established in 2000 to investigate the causes of cancer and chronic disease. The cohort consists of almost 55 000 participants aged 35–69 years at the time of recruitment. From 2020 to 2022, ATP conducted a longitudinal substudy, the COVID-19 Antibody Testing (CAT) study, nested in this existing cohort, to understand the spread and impact of the SARS-CoV-2. In this cohort profile, we describe the CAT study design, recruitment and initial findings.

Participants

In this prospective cohort substudy, ~4000 participants completed online surveys and provided blood samples at a study centre every 4 months for 1 year, across four cities in Alberta, Canada. The study was launched on a rolling basis beginning in September 2020 and data collection was completed in May 2022. The surveys collected information on health and lifestyle factors, COVID-19 (testing, symptoms, vaccination, public health recommendations) and impacts of the pandemic (including economic, health services, mental health). Blood samples were tested for antinucleocapsid and antispike protein SARS-CoV-2 antibodies.

Findings to date

A total of 4102 participants consented and attended a study centre at baseline, and almost 90% of these completed the study. Overall, participants were aged 61±10 years, 60% female, 12% came from rural areas, 45% had at least a bachelor’s degree, 24% reported a household income 4 weeks). By the end of the study, 96% of participants had received at least one COVID-19 vaccine dose. Through investigating other outcomes, it was observed that participants under 50 years of age were more likely to be assessed to have mild or moderate-to-severe anxiety and depressive symptoms compared with older participants. In addition, approximately 15% of participants reported a moderate to major impact on their ability to meet financial obligations.

Future plans

Serology results, together with health, lifestyle and sociodemographic data, and the continued follow-up of these participants as part of the broader ATP cohort study (planned through 2065), will provide opportunities to investigate the long-term sequelae of COVID-19 infection as well as the broader impacts of the pandemic on physical, mental and emotional health.

Background

In Tanzania, acute myocardial infarction (AMI) is underdiagnosed, and uptake of evidence-based care is suboptimal. Using an implementation science approach, an intervention was developed to address local barriers to care: the Multicomponent Intervention for Improving Myocardial Infarction Care in Tanzania (MIMIC).

Methods

This sequential cohort design trial was conducted in a single northern Tanzanian emergency department (ED). During the preintervention phase (February–August 2023) and the postintervention phase (September 2023–August 2024), adults presenting with chest pain and/or dyspnoea were prospectively enrolled and their ED care was observed. AMI was defined by the Fourth Universal Definition criteria. Telephone follow-ups were conducted to ascertain 30-day mortality. Pearson’s ² was used to compare care before and after MIMIC implementation.

Results

A total of 275 participants were enrolled in the preintervention phase and 577 were enrolled in the postintervention phase. Following MIMIC implementation, significant increases were observed in ECG testing (89.4% of postintervention participants vs 55.3% preintervention, OR 6.82, 95% CI 4.79 to 9.79, p

Conclusions

The MIMIC intervention was associated with large increases in uptake of AMI testing, case identification and evidence-based treatment in a single Tanzanian ED. Multisite studies are needed to evaluate the effect of MIMIC on AMI care in diverse settings across Tanzania.

Por: Hovsepjan · V. · Thijs · A. · van Diemen · J. J. K. · Bogaards · J. A. · Winter · M. M. · Bosmans · J. E. · Prins · J. M. · ASCAP study group · Altenburg · Bogaards · Bosmans · van Diemen · Hovsepjan · Prins · Thijs · Winter · Fritsma-Terwisscha van Scheltinga · Weijer · Berk · H
Introduction

Cardiovascular events (CVEs), in particular acute coronary syndrome (ACS), complicate the course of a significant number of patients hospitalised for community-acquired pneumonia (CAP) or influenza. Emerging evidence suggests that this increased risk of CVEs could be mitigated by the use of acetylsalicylic acid (aspirin). The ASCAP study investigates whether the addition of aspirin to standard therapy in hospitalised patients with moderate-to-severe CAP or influenza can reduce the incidence of CVEs.

Methods and analysis

The ASCAP study is a multicentre, double-blind, placebo-controlled randomised trial in 16 university and general hospitals in the Netherlands, in which patients are randomised to acetylsalicylic acid or matching placebo for 90 days. Eligible patients are adults hospitalised for moderate-to-severe CAP or influenza. Patients with antithrombotic or anticoagulant drugs, or those with contraindications for aspirin, are excluded. The primary outcome is the incidence of ACS up to day 180. Secondary outcomes include the incidence of 4-point major adverse cardiovascular events up to day 180, as well as the incidence of major bleeding and clinically relevant non-major bleeding events up to day 90, all-cause mortality up to day 180 and quality of life and societal costs up to day 180. Survival time will be analysed by the log-rank test, stratified for CAP and influenza, with a two-sided alpha of 0.05. Assuming an average baseline ACS risk of 7.5% over 180 days with up to 30% variation across strata, and a 60% hazard reduction due to aspirin, the required sample size to achieve 80% power is 760 patients. Currently, 114 patients are enrolled in the study.

Examining the role of staff and team communication in reducing seclusion, restraint and forced tranquilisation in acute inpatient mental health settings: protocol for the Communication and Restraint Reduction (CaRR) study

Por: Cibelli · F. · Forbes · T. · McCabe · R. · Anderson · J. E. · Hoe · J. · Tahir · S. · McKeown · G. J. · Brew · B. · Deamer · F. · Lavelle · M.
Introduction

Over 100 000 service users are admitted to acute mental health wards annually, many involuntarily. Wards are under incredible pressure due to high bed occupancy rates and staff shortages. In a recent survey, over 80% of mental health nurses reported experiencing aggression and violence within their role. National and international policy dictates that mental health ward staff manage incidents of aggression and violence using communication, known as de-escalation. However, de-escalation practice is variable, and there is little empirical evidence to underpin training. As such, there is still a reliance on more restrictive practices, including seclusion and physical restraint.

Aim

The aim of this study is to identify the communication and organisational factors that characterise effective management of service users’ behaviour and distress in acute adult inpatient mental health wards, reducing the reliance on more restrictive practices (eg, seclusion and restraint).

Methods and analysis

This observational study will be conducted on mental health wards in England. It will be comprised of three work packages (WPs).

  • A microanalysis of communication during de-escalation incidents from Body Worn Camera footage on wards (n=64), to identify staff communication practices that lead to effective management of service users’ distress.

  • Ethnographic observations of ward routine practice, alongside interviews and questionnaires with staff and service users, to examine how challenging behaviour is anticipated, planned for and responded to on wards, and staff experiences and perceptions of this process.

  • Triangulation of the findings from WPs 1 and 2 to examine the relationship between approaches to aggression management and staff communication, exploring the similarities and differences within and between wards.

  • Ethics and dissemination

    Ethical approval for sites in England has been granted by the Wales Research Ethics Committee 3, REF 22/WA/0066. Findings will be disseminated through peer-reviewed journals, scientific conferences and service user and clinical networks.

    Association between ABO blood group and blood component transfusion requirements in dengue infection: a retrospective study from a tertiary hospital in Kerala, India

    Por: Cherupanakkal · C. · Jacob · A. · Olickal · J. J. · Varughese · J. E. · Thampi · A. · Jacob · A. A. · Mathew · R. · Jayaprasad · G. · Varghese · J. E.
    Objective

    Platelet and fresh frozen plasma (FFP) transfusions are routinely employed in the management of severe dengue. Previous research has indicated a potential link between ABO blood groups and susceptibility to dengue, with evidence suggesting that mosquito vector feeding preferences may be influenced by host blood type. These factors could potentially impact transfusion demands during outbreaks. This retrospective study aimed to investigate the relationship between ABO blood groups and transfusion requirements in patients with dengue.

    Design

    Retrospective study.

    Setting

    The study was conducted at a tertiary care hospital in Kerala.

    Methods

    Clinical and laboratory data were reviewed for 199 patients confirmed with dengue who received blood component transfusions and compared with two control groups: 200 randomly selected patients with dengue who did not require transfusions and 200 patients without dengue who required transfusions, over a period spanning January 2015 to March 2023.

    Results

    Among transfused dengue cases, blood groups O (41.71%), A (28.14%) and B (23.12%) were most prevalent; however, no statistically significant association was observed between ABO blood group and transfusion requirement. Furthermore, the total volumes of FFP and platelet transfusions did not differ significantly across ABO groups among patients with dengue. Notably, platelet transfusions were significantly more frequent in dengue cases (92.0%) compared with transfused patients without dengue (35.5%), whereas FFP transfusions were more common in non-dengue transfused cases (84.5%) than in patients with dengue (44.7%). Patients with dengue also received significantly higher mean volumes of both FFP and platelets.

    Conclusion

    Despite earlier reports linking ABO blood types to dengue susceptibility, this study found no significant association with transfusion requirements, warranting confirmation through larger multicentre studies.

    Comparative effectiveness of take-home dosing schedules for opioid agonist treatment in British Columbia, Canada: a target trial emulation protocol using a population-based observational study

    Introduction

    The introduction of fentanyl and its analogues in the illicit drug supply has prompted greater emphasis on refining clinical treatment protocols to ensure sustained retention in opioid agonist treatment (OAT). Take-home dosing may lessen the treatment burden on clients and thus reduce the risk of treatment discontinuation. The evidence base supporting the use of take-home dosing, including the optimal duration of dispensations, is, however, limited. The objective of this study is to determine the comparative effectiveness of alternative take-home dosing schedules, as observed in clinical practice in British Columbia, Canada from 2010 to 2022.

    Methods and analysis

    We propose to emulate a target trial with a population-level retrospective study of individuals initiating methadone or buprenorphine/naloxone between 1 January 2010 and 31 December 2022 who are 18 years of age or older and not currently incarcerated or pregnant with no history of cancer or palliative care. Our study will draw on nine linked health administrative databases from British Columbia and will evaluate take-home doses of 2–5 days, 6 days or >6 days compared with continuous daily dosing. The primary outcomes include OAT discontinuation and all-cause mortality on treatment. A causal per-protocol analysis is proposed with longitudinal matching and inverse probability of censoring weighting approaches to adjust for time-fixed and time-varying confounding. A range of sensitivity analyses will be executed to determine the robustness of results.

    Ethics and dissemination

    The protocol, cohort creation and analysis plan have been classified and approved as a quality improvement initiative by Providence Health Care Research Ethics Board and the Simon Fraser University Office of Research Ethics. Results will be disseminated and shared with local advocacy groups and decision-makers, developers of national and international clinical guidelines, presented at national and international conferences and published in peer-reviewed journals electronically and in print.

    Evaluating care pathways in Alzheimers disease: a qualitative interview study with GPs in England

    Por: Carter · M. · Butterworth · J. E. · Fox · C. · Allan · L.
    Aim

    To understand general practitioners’ (GPs’) experience of existing care pathways for people with moderate-severe Alzheimer’s Disease (AD) and explore their attitudes towards potential modifications to these pathways.

    Design

    Secondary thematic analysis of qualitative interviews, originally conducted with GPs to explore prescribing of memantine in general practice. The theoretical domains framework was used to structure the data.

    Setting

    The study participants were recruited via an online survey completed by GPs across England.

    Participants

    Semi-structured, qualitative interviews were conducted with thirteen male and ten female GPs from a range of general practices in England.

    Primary outcome

    Insights into GPs’ views and experiences regarding existing and possible care pathways for individuals with moderate to severe AD.

    Results

    Gaps in GPs’ current levels of knowledge and skill in respect of caring for patients with moderate-to-severe AD affect their confidence and ability to identify opportunities for additional treatments. While GPs emphasise their role as providers of holistic care, features of the current healthcare context, including a lack of additional funding, inhibit their willingness to assume additional responsibilities as part of a revised pathway.

    Conclusion

    A considerable knowledge, skills and confidence gap must be addressed to support the implementation of new care pathways that include revised responsibilities for GPs. GPs need appropriate support and resources to manage their patients’ changing needs and to provide the best possible pharmacological management as the disease develops.

    Introduction

    Mycobacteroides abscessus (MABS) is within the non-tuberculous mycobacteria family. It inhabits soil and water, exhibits multi-antibiotic resistance and causes opportunistic lung infections, which may progress to symptomatic MABS-pulmonary disease (MABS-PD) associated with substantial morbidity, increased healthcare utilisation, impaired quality of life and increased mortality. Treatment regimens for MABS-PD are highly variable, not evidence-based and involve complex, expensive drug combinations administered for prolonged periods (>12 months) with frequent adverse effects and treatment failure. There is an urgent need for safe, efficacious and cost-effective MABS-PD therapy. Here, we describe the Master Protocol for the Finding the Optimal Regimen for Mycobacteroides abscessus Treatment (FORMaT) trial. FORMaT aims to determine the most effective and best tolerated treatment for MABS-PD as defined by MABS clearance from respiratory samples with good treatment tolerance.

    Methods and analysis

    FORMaT is an international multicentre, adaptive platform trial evaluating treatment combinations for MABS-PD. Participants are randomised multiple times during the trial, with assessment of the primary outcome of clearance of MABS infection with good treatment tolerance. Initially, therapies recommended in international consensus guidelines are being tested. Data obtained will eliminate therapies lacking efficacy or causing unacceptable toxicity. Novel treatments can then be added and tested against previously determined optimal approaches, leading in an iterative fashion to improved microbiological clearance and health outcomes. In parallel, an Observational cohort and several integrated and discovery studies are embedded in FORMaT to identify biomarkers of MABS-PD and MABS clearance, clinical and radiographic treatment response, drug pharmacokinetics and Mycobacteroides genomics and resistome.

    Ethics and dissemination

    The FORMaT Master Protocol and related documents are approved by regulatory authorities in each participating jurisdiction and/or site. Results will be published in peer-reviewed journals and presented at scientific meetings. De-identified, aggregated data will be shared on an approved online platform.
