Perceptions of an AI-based clinical decision support tool for prescribing in multiple long-term conditions: a qualitative study of general practice clinicians in England

Por: dElia · A. · Morris · S. G. · Cooper · J. · Nirantharakumar · K. · Jackson · T. · Marshall · T. · Fitzsimmons · L. · Jackson · L. J. · Crowe · F. · Haroon · S. · Greenfield · S. · Hathaway · E.
Background

Artificial intelligence (AI)-based clinical decision support systems (CDSSs) are currently being developed to aid prescribing in primary care. There is a lack of research on how these systems will be perceived and used by healthcare professionals and subsequently on how to optimise the implementation process of AI-based CDSSs (AICDSSs).

Objectives

To explore healthcare professionals’ perspectives on the use of an AICDSS for prescribing in co-existing multiple long-term conditions (MLTC), and the relevance to shared decision making (SDM).

Design

Qualitative study using template analysis of semistructured interviews, based on a case vignette and a mock-up of an AICDSS.

Setting

Healthcare professionals prescribing for patients working in the English National Health Service (NHS) primary care in the West Midlands region.

Participants

A purposive sample of general practitioners/resident doctors (10), nurse prescribers (3) and prescribing pharmacists (2) working in the English NHS primary care.

Results

The proposed tool generated interest among the participants. Findings included the perception of the tool as user friendly and as a valuable complement to existing clinical guidelines, particularly in a patient population with multiple long-term conditions and polypharmacy, where existing guidelines may be inadequate. Concerns were raised about integration into existing clinical documentation systems, medicolegal aspects, how to interpret findings that were inconsistent with clinical guidelines, and the impact on patient-prescriber relationships. Views differed on whether the tool would aid SDM.

Conclusion

AICDSSs such as the OPTIMAL tool hold potential for optimising pharmaceutical treatment in patients with MLTC. However, specific issues related to the tool need to be addressed and careful implementation into the existing clinical practice is necessary to realise the potential benefits.

'I think it depends how its done: a qualitative study of screening attendees perspectives on receiving physical activity advice within UK NHS cancer screening programmes

Por: Murphy · J. · Stevens · C. · Roberts · A. L. · Vrinten · C. · Waller · J. · Smith · S. G. · Beeken · R. J.
Objectives

Cancer screening appointments are an opportunity to encourage positive behavioural changes. Up to 80% of cancer screening attendees are open to discussing physical activity during cancer screening, but some say this would deter them from future screening. This study aimed to gain an in-depth understanding of individuals’ receptivity to physical activity advice at cancer screening.

Design

Interview-based qualitative study.

Setting and participants

The study was conducted from May 2017 to September 2018 in the UK. Participants were recruited using adverts on two university campuses, Facebook and a participant recruitment agency. To be eligible, participants had to have an upcoming cancer screening appointment within 2 weeks. There were 30 participants.

Procedures

Participants recorded their receptivity to physical activity advice in the days before and after screening. Data-prompted semi-structured interviews explored these responses. Interviews were analysed using a thematic framework analysis.

Results

Participants felt discussing physical activity at cancer screening would be relevant. However, participants experienced anxiety related to the screening process which could increase or decrease their receptivity. Participants felt if information was delivered in a judgemental way, it could negatively impact future screening participation.

Conclusions

Screening attendees’ receptivity could be influenced by the timing of a discussion and by their levels of anxiety throughout screening. Participants’ anxiety during screening can either reduce their ability to engage in a discussion or increase the relevance of the discussion. The communication style of the healthcare practitioner was key for why some screening attendees could be deterred from future cancer screening.

Continuous non-invasive electrophysiological monitoring in high-risk pregnancies: study protocol of a cohort intervention random sampling study in a tertiary obstetrical care centre in the Netherlands (NIEM-O study)

Por: de Klerk · N. D. · Berben · P. B. Q. · de Vries · I. R. · Niemarkt · H. · Vullings · R. · van den Heuvel · E. R. · van der Ven · M. · Fransen · A. F. · Oei · S. G. · van Laar · J. O. E. H.
Introduction

Women with high-risk pregnancies (eg, pre-eclampsia, imminent preterm birth) are often hospitalised due to the need for foetal and maternal monitoring. They are monitored for 30–45 min up to three times a day with conventional cardiotocography (CTG). In the meantime, they reside at the hospital, but the foetal status is not monitored. Continuous foetal monitoring is currently not recommended using CTG, due to the potential temperature rise from consistent exposure to ultrasound waves. For safe 24/7 monitoring, newly developed devices using non-invasive electrophysiological cardiotocography (eCTG) instead of conventional CTG offer a promising alternative. Previous research into eCTG has shown favourable results in monitoring foetal heart rate throughout both pregnancy and labour. This study aims to investigate the effect of implementing continuous antepartum eCTG monitoring in hospitalised high-risk pregnancies on perinatal and maternal outcome.

Methods and analysis

In this single centre prospective cohort intervention random sampling study, eligible women will be included on the Obstetric High Care of Máxima MC Veldhoven, the Netherlands. In total, 511 pregnant women with a singleton pregnancy between 23+0 and 32+0 weeks of gestation requiring hospitalisation will be recruited. Eligible women will be prospectively included in the cohort receiving standard treatment: intermittent CTG monitoring. From these women, a random sample of the prospective cohort will be offered a new monitoring method: 24/7 eCTG monitoring. For the eCTG monitoring, a wireless abdominal electrode patch, the Nemo Foetal Monitoring System will be used. Additional data from a historical cohort (2014–2019) of 1400 women receiving standard treatment will be included. Perinatal and maternal outcome, along with satisfaction levels of both patient and caregivers, will be compared between groups.

Ethics and dissemination

The study is registered on 18 October 2022 to the Central Committee on Research Involving Human Subjects (NL82869.015.22) via https://www.toetsingonline.nl/to/ccmo_monitor.nsf/conceptabr?OpenForm and approved by the Medical Ethics Committee of Máxima MC (W22.070) on 7 November 2023. Results of the study will be disseminated in peer-reviewed scientific journals and conference presentations.

Por: Schladitz · K. · Buss · A. · Pabst · A. · Welzel · F. D. · Blüher · M. · Stumvoll · M. · Brettschneider · C. · König · H.-H. · Riedel-Heller · S. G. · Löbner · M.
Introduction

Patients with chronic somatic diseases such as obesity often develop comorbid depressive symptoms. E-mental health interventions are an innovative and effective treatment option within a stepped care approach. Studies have shown that acceptance and adherence are higher when they are tailored to the specific needs of the target group. This study protocol describes a randomised controlled trial (RCT) of an internet-based self-help intervention, Fit4Mood, to improve mental health in the high-risk group of adults with obesity. The objective of the @ktivPLUS research project is to evaluate the effectiveness, acceptability and cost-effectiveness of the intervention in comparison to an online bibliotherapy.

Methods and analysis

Eligible individuals will be randomly allocated to an intervention group (access to an internet-based intervention) or to an active control group (access to an online bibliotherapy). Assessments will be conducted before the start of the intervention (baseline (BL)) and 4 months after BL (follow-up (FU)). The primary outcome is the reduction in depressive symptoms (Beck Depression Inventory-II) in n=190 participants. Secondary outcomes are anxiety, quality of life, activity, self-efficacy, resilience, mental and digital health literacy, stress, sleep quality, weight loss, weight management activities and readiness to lose weight, weight self-stigma, uptake, adherence and satisfaction with the intervention, workability and cost-effectiveness at follow-up. Additionally, sociodemographics, health, comorbidities and disabilities, as well as internet-specific information, will be assessed at BL. Intention-to-treat analysis using generalised linear mixed models will be applied.

Ethics and dissemination

Approval for this study has been granted by the ethics committee of the University of Leipzig (ID: 140/25-ek). All participants will provide informed consent prior to participation in the study. Results will be disseminated in peer-reviewed journals and presented at national and international conferences. In the case of a successful evaluation, the internet-based self-help intervention Fit4Mood will be provided as freeware, which will be easily accessible and free of charge.

Trial registration number

The current RCT study has been registered at the German Clinical Trials Register (Identifier: DRKS00036178, Registered 24 June 2025; https://www.drks.de/search/de/trial/DRKS00036178).

Evaluating the scale-up of the Play Active programme for childrens physical activity in early childhood education and care services: a national type III hybrid effectiveness-implementation trial protocol

Por: Christian · H. · Maher · C. · Trost · S. G. · Schipperijn · J. · Murray · K. · Li · I. · Nathan · A. · Papageorgiou · A. · Mclaughlin · M. · Bauman · A.
Introduction

Physical activity is crucial for young children’s health and development. Many young children do not meet the recommended 3 hours of daily physical activity, including 60 min of energetic play. Early childhood education and care (ECEC/childcare) is a key setting to intervene to improve children’s physical activity. The Play Active programme is a scalable evidence-informed ECEC-specific physical activity policy intervention with implementation support strategies to improve educators’ physical activity-related practices.

Methods and analysis

This hybrid type III effectiveness-implementation trial will use a quasi-experimental repeated measures design to assess the real-world effectiveness of Play Active’s scalable implementation support strategies in helping ECEC services adopt the practices included in the Play Active policy. Secondary aims will examine changes in educator-reported and device-measured children’s physical activity; assess the sustainability of the programme; identify effective dissemination strategies; assess cost-effectiveness; and involve comprehensive process evaluation. All ECEC services in Western Australia (n=776), Queensland (n=1744) and South Australia (n=445) will be invited to participate. Data will be collected at baseline, 6, 12, 18, 24 and 30 months.

Ethics and dissemination

Ethics approval has been provided by The University of Western Australia Human Research Ethics Committee (HREC) (2023/ET000187), the University of Queensland HREC (2024/HE000076) and the University of South Australia HREC (206023). This real-world trial of Play Active is vital for understanding its implementation in practice and to generate evidence for further scale-up and roll-out nationally. Key findings will be disseminated to stakeholders, collaborators, policy-makers as well as families and practitioners in the ECEC sector.

Development and validation of diagnostic and prognostic prediction tools for dental caries in young children through prospective and cross-sectional observational studies: a protocol

Por: Khazaei · Y. · Kodikara · S. · Butler · C. A. · Messina · N. L. · Le Cao · K.-A. · Dashper · S. G. · Silva · M. J.
Introduction

Dental caries is the most common oral disease worldwide, affecting up to 90% of children globally. It can lead to pain, infection and impaired quality of life. Early prevention is a key strategy for reducing the prevalence of dental caries in young children. Valid and reliable diagnostic or prognostic tools that enable accurate individualised prediction of current or future dental caries are essential for facilitating personalised caries prevention and early intervention. However, no efficacious tools currently exist in early childhood—the optimal period for disease prevention. We aim to develop and validate diagnostic and prognostic prediction tools for dental caries in young children, using a combination of environmental, physical, behavioural and biological early life data.

Methods and analysis

Data sources include two prospective studies, with a total sample size of approximately 600 children. These cohorts have collected detailed demographic, antenatal, perinatal and postnatal data from medical records and parent-completed questionnaires and biological samples including a dental plaque swab. Candidate predictor variables will include sociodemographic characteristics, health history, behavioural and microbiological characteristics. The outcome variable will be the presence, incidence or severity of dental caries diagnosed using the International Caries Detection and Assessment System. Statistical and machine learning approaches will be used for selection of predictor variables and model development. Internal validation will be conducted using resampling methods (i.e., bootstrapping) and nested cross-validation. Model performance will be evaluated using standard performance metrics such as accuracy, discrimination and calibration. Where feasible, external validation will be performed in an independent cohort. Model development and reporting will be guided by the Transparent Reporting of a multivariable prediction model for Individual Prognosis or Diagnosis (TRIPOD) statement and the Prediction model Risk Of Bias Assessment Tool (PROBAST) guidelines.

Ethics and dissemination

This study has ethical and governance approval from The Royal Children’s Hospital Melbourne Human Research Ethics Committee (HREC/111803/RCHM-2024). Results of this study will be published in peer-reviewed journals and presented at scientific conferences.

Study protocol for an open-label, single-arm, mixed methods feasibility study of the MWIQ AI-powered decision support tool for diabetes management in GP practices

Por: Dickson · J. · Cunningham · S. G. · Sainsbury · C. · Rutter · M. K. · Kanumilli · N. · Pearson · E. · Brodie · D. · Stevens · M. · Wake · D. J. · Conway · N.
Introduction

Diabetes affects ~10% of the world’s population and is rising. Treatment costs in the UK are ~15% of the NHS budget. Diabetes-related complications can be lowered through better evidence-based clinician management and patient self-management. MyWay intelligence quotient (MWIQ) is an electronic platform that will provide clinical decision support around the diagnosis and treatment of patients with diabetes. This study evaluates the safety and clinical performance (clinical appropriateness/applicability, clinical impact and clinical usability) of MWIQ.

Methods and analysis

The system will be implemented in real time in four to seven general practitioner (GP) practices. Clinicians with diabetes expertise will be recruited as validators, who will inspect records to ensure system robustness before use, and up to 14 healthcare professionals will use and evaluate the system.

Quantitative and qualitative analyses will be triangulated to assess the MWIQ system. Assessment of clinical outcomes will be made using pseudonymised routinely collected clinical data, including adherence to quality performance indicators, diabetes diagnosis, diabetes investigations (eg, genetic testing), HbA1c, blood pressure, body mass index, cholesterol and foot risk score for the diabetes population concerned. Clinical and validator participants will also submit a weekly questionnaire, and these, along with interviews, which are scheduled during the testing process, will be analysed to provide data on the utility, safety and usability of the system.

Ethics and dissemination

This study was approved, 08/01/2024, by the North of Scotland Research Ethics Committee (REC), IRAS project ID: 305267, REC, reference 23/NS/0134. The study has gained confidentiality advisory group (CAG) support (reference: 24/CAG/0002), medicines and healthcare products regulatory agency (MHRA) and health research authority (27/08/2024) approvals.

Findings will be reported to (1) The funding body, (2) The participating GP practices, (3) The study PPIE group, (4) The MHRA to support a submission for recognition as a class 2 CE/UKCA marked device, (5) Presented at local, national and international conferences and (6) Disseminated by peer-reviewed publications.

Getting recovery right after neck dissection for head and neck cancer (GRRAND): trial protocol for a multicentre, pragmatic randomised controlled trial with health economic evaluation and process evaluation

Por: Evans · C. · Greene · L. · Hossain · A. · Klear · P. · Ratna · M. · Bradley · H. · Lall · R. · Mistry · H. · Naghdi · S. · Reategui · M. · Stevens · T. · Bruce · J. · Price · R. · Schache · A. · Dean · S. G. · Lamb · S. E. · Smith · T. · Winter · S. C.
Introduction

Head and neck cancer (HNC) affects the mouth, throat, salivary glands, voice box, nose or sinuses. Every year, over 12 000 people in the UK are diagnosed with HNC. Neck dissection is a key, surgical component of patient care. However, many people experience postoperative restriction in shoulder and neck movements, pain, fatigue and low mood, with only half ever returning to work.

Methods and analysis

Getting Recovery Right After Neck Dissection (GRRAND) is a two-arm, multicentre, pragmatic randomised controlled trial. The trial aims to compare clinical and cost-effectiveness of a personalised physiotherapy programme (GRRAND programme) versus usual practice, National Health Service (NHS), postdischarge care.

The planned sample size is 390 participants. Participants will be recruited from across UK sites and followed up for 12 months. The primary outcome is the shoulder pain and disability index at 12 months. Economic evaluation will be conducted from a healthcare system and personal social services perspective. Secondary outcome data, including pain, function, health-related quality of life, mental well-being, health resource use and adverse events, will be collected at 6 weeks, 3, 6 and 12 months, with exercise adherence at 6 weeks. A process evaluation will determine how GRRAND is implemented, delivered and received across clinical settings, exploring what works, for whom and under what conditions. Analysis will be on an intention-to-treat basis and reported inline with the Consolidated Standards of Reporting Trials statement.

Ethics and dissemination

The trial was approved by the London-Brent Research Ethics Committee (ref: 24/LO/0722) on 15 October 2024. Trial results will be disseminated via peer-reviewed publications, presentations at national and international conferences, in lay summaries and social media. This protocol adheres to the recommended Standard Protocol Items: Recommendations for Interventional Trials checklist.

How do primary care consultation dynamics affect the timeliness of cancer diagnosis in people with one or more long-term conditions? A qualitative study

Por: Valasaki · M. · Carter · M. · Winder · R. · Shephard · E. · Valderas · J. M. · Merriel · S. W. D. · Farmer · L. · Summers · B. · Dean · S. G. · Morgan-Trimmer · S.
Objectives

To explore how pre-existing conditions affect the diagnostic process for potential cancer in primary care patients.

Design

Qualitative interview study using thematic analysis underpinned by a critical realist approach.

Setting

Primary care practices recruited through four Clinical Research Networks and UK health charities across England.

Participants

Interviews were conducted with 75 patients with one or more pre-existing conditions (anxiety/depression, diabetes, obesity, chronic obstructive pulmonary disease, Parkinson’s disease or multiple long-term conditions (four or more)) and 28 primary care professionals (general practitioners and nurses).

Results

The study identified legitimacy as a central theme influencing patient trajectories in the health system while trying to receive a diagnosis for symptoms with which they presented to primary care. Patients engaged in self-triage to determine whether symptoms were ‘legitimate’ enough to seek care. Subsequent triaging steps (by receptionists, nurses and online systems) acted as gatekeepers, with decisions influenced by effectiveness of describing the symptom and subjective impressions. During consultations, clinicians relied on a mix of symptom narrative clarity, medical history and objective ‘metrics’ (eg, blood results, family history) to determine legitimacy for further investigations. Pre-existing conditions could either lower the threshold for referrals or obscure potential cancer symptoms. The stigma associated with mental health diagnoses often undermined perceived legitimacy and contributed to delays.

Conclusions

Legitimacy is continuously negotiated throughout the diagnostic pathway. It is shaped by social, moral and biomedical judgements. To promote early cancer diagnosis for patients with pre-existing conditions, clinicians must make legitimacy assessments explicit, reduce stigma especially around mental health and standardise triage processes.

Personalised Exercise Rehabilitation FOR people with Multiple long-term conditions (PERFORM): findings from a process evaluation of a randomised feasibility study

Por: Brown · S. E. · Simpson · S. A. A. · Greaves · C. · Daw · P. · Dean · S. G. · Evans · R. A. · Withers · T. M. · Ahmed · Z. · Barber · S. · Barwell · G. · Doherty · P. J. · Gardiner · N. · Ibbotson · T. · Jani · B. · Jolly · K. · Mair · F. · Manifield · J. R. · McIntosh · E. · Miller · D. · O
Objective

The number of people living with multiple long-term conditions (MLTCs or ‘multimorbidity’) is growing. Evidence indicates that exercise-based rehabilitation can improve health-related quality of life and reduce hospital admissions for a number of single long-term conditions. However, it is increasingly recognised that such condition-focused rehabilitation programmes do not meet the needs of people living with MLTCs. The aims for this study were to (1) evaluate the acceptability and feasibility of the newly developed Personalised Exercise Rehabilitation FOR people with Multiple long-term conditions (PERFORM) intervention; (2) assess the feasibility of study methods to inform progression to a definitive randomised controlled trial (RCT) and (3) refine our intervention programme theory.

Design

Semi-structured qualitative interviews were conducted with patients receiving and healthcare practitioners delivering the PERFORM intervention, to seek their experiences of the intervention and taking part in the study. Interviews were analysed thematically, informed by Normalisation Process Theory and the programme theory.

Setting

Three UK sites (two acute hospital settings, one community-based healthcare setting).

Participants

18 of the 60 PERFORM participants and 6 healthcare professionals were interviewed.

Intervention

The intervention consisted of 8 weeks of supervised group-based exercise rehabilitation and structured self-care symptom-based support.

Results

All participants and staff interviewed found PERFORM useful for physical and mental well-being and noted positive impacts of participation, although some specific modifications to the intervention delivery and training and study methods were identified. Scheduling, staffing and space limitations were barriers that must be considered for future evaluation and implementation. Key intervention mechanisms identified were social support, patient education, building routines and habits, as well as support from healthcare professionals.

Conclusions

We found the PERFORM intervention to be acceptable and feasible, with the potential to improve the health and well-being of people with MLTCs. The findings of the process evaluation inform the future delivery of the PERFORM intervention and the design of our planned full RCT. A definitive trial is needed to assess the clinical and cost-effectiveness.

Personalised exercise-rehabilitation for people with multiple long-term conditions (PERFORM): a randomised feasibility study

Por: Evans · R. A. · Simpson · S. A. · Manifield · J. R. · Ahmed · Z. · Barber · S. · Barwell · G. · Brown · S. E. · Daw · P. · Dean · S. G. · Doherty · P. J. · Fraser · H. · Gardiner · N. · Greaves · C. · Ibbotson · T. · Jani · B. · Jolly · K. · Mair · F. · McIntosh · E. · Megaritis · D. · Mille
Objective

Existing exercise-based rehabilitation services, such as cardiac and pulmonary rehabilitation, are traditionally commissioned around single long-term conditions (LTCs) and therefore may not meet the complex needs of adults with multiple long-term conditions (MLTCs) or multimorbidity. The aim of this study was to assess the feasibility and acceptability of the newly developed personalised exercise-rehabilitation programme for people with multiple long-term conditions (PERFORM) and the trial methods.

Design

A parallel two-group mixed-methods feasibility randomised controlled trial (RCT) with embedded process and economic evaluation.

Setting

Three UK sites (two acute hospital settings, one community-based healthcare setting).

Participants

60 adults with MLTCs (defined as the presence of ≥2 LTCs) with at least one known to benefit from exercise therapy were randomised 2:1 to PERFORM intervention plus usual care (PERFORM group) or usual care alone (control group).

Intervention

The intervention consisted of 8 weeks of supervised group-based exercise rehabilitation and structured self-care symptom-based support.

Primary and secondary outcome measures

Primary feasibility outcomes included: trial recruitment (percentage of a target of 60 participants recruited within 4.5 months), retention (percentage of participants with complete EuroQol data at 3 months) and intervention adherence (percentage of intervention group attending ≥60% sessions). Other feasibility measures included completion of outcome measures at baseline (pre-randomisation), 3 months post-randomisation (including patient-reported outcomes, exercise capacity and collection of health and social care resource use) and intervention fidelity.

Results

Target recruitment (40 PERFORM group, 20 control group) was met within the timeframe. Participants were 57% women with a mean (SD) age of 62 (13) years, body mass index of 30.8 (8.0) kg/m2 and a median of 4 LTCs (most common: diabetes (41.7%), hypertension (38.3%), asthma (36.7%) and a painful condition (35.0%)). We achieved EuroQol outcome retention of 76.7% (95% CI: 65.9% to 87.1%; 46/60 participants) and intervention adherence of 72.5% (95% CI: 56.3% to 84.4%; 29/40 participants). Data completion for attendees was over 90% for 11/18 outcome measures.

Conclusions

Our findings support the feasibility and rationale for delivering the PERFORM comprehensive self-management and exercise-based rehabilitation intervention for people living with MLTCs and progression to a full multicentre RCT to formally assess clinical effectiveness and cost-effectiveness.

Tirzepatide for the treatment of adults living with concurrent type 1 diabetes and overweight or obesity (TZP-T1D): a double-blind, placebo-matched randomised controlled trial protocol

Por: Purcell · A. R. · Rodrigo · N. · Longfield · M. S. G. · Glastras · S. J.
Introduction

The increasing prevalence of overweight and obesity among individuals with type 1 diabetes (T1D) complicates glycaemic management and escalates insulin resistance, necessitating innovative therapeutic strategies. Tirzepatide, a dual agonist for glucagon-like peptide-1 and glucose-dependent insulinotropic polypeptide receptors, shows promise in managing weight and glycaemic control in type 2 diabetes but is unexplored in the context of T1D. This double-blind, placebo-controlled randomised trial will evaluate the efficacy of tirzepatide in adults with T1D and overweight/obesity over 32 weeks.

Methods and analysis

60 participants (aged 18–70 years) with a body mass index ≥27 kg/m2 and HbA1c≤10% will be randomised 1:1 to receive either tirzepatide or a placebo, alongside standard insulin therapy. The primary outcome is the change in body weight (%). Secondary measures include change in HbA1c (%), proportion of body weight lost (>5%, >10%, >15% and >20%), changes in insulin dosage, time in range by continuous glucose monitoring (CGM) criteria and severity of comorbidities. Compliance, adverse events and medication interactions will be closely monitored, with adjustments made for tolerability. Patient-reported outcomes and experiences will be measured to capture the benefits of glycaemic management, weight management and quality of life. To compare the means of body weight reduction (%) between the tirzepatide and control groups, an independent samples t-test will be employed under the assumption that data are normally distributed. Secondary outcome measures will be analysed by Student’s t-test. All data will be reported as group means with confidence intervals, with default statistical significance assumed at p

Transcranial direct current stimulation combined with physical exercise in knee osteoarthritis: a protocol for a randomised controlled clinical trial

Por: Lima · V. B. · Silva · C. A. M. · Silva · S. G. D. d. · Macedo · L. d. B. · de Souza · M. C. · Lins · C. A. d. A. · de Souza · C. G.
Introduction

Osteoarthritis (OA) is a degenerative and progressive joint condition causing pain and disability. Physical exercise is recognised as the most effective intervention since individuals with this condition often experience muscle weakness, balance deficits and chronic pain. Additionally, knee osteoarthritis (KOA) is associated with central sensitisation, contributing to chronic pain conditions. Transcranial Direct Current Stimulation (tDCS), a non-invasive neuromodulation technique, has been employed to induce changes in pain perception by altering cortical excitability, potentially reducing chronic pain.

Methods and analysis

This is a protocol for a randomised controlled trial. Participants will be allocated to two groups: G1 (active tDCS combined with exercise) and G2 (sham tDCS combined with exercise). The intervention protocol will last for 5 weeks, with two sessions per week on non-consecutive days. Pain intensity will be assessed as the primary outcome using the Numeric Rating Scale (NRS). The sample size was calculated based on a minimum clinically important difference of 3 points on the NRS between groups, with a statistical power of 80% and a significance level of 5%. Secondary outcomes will include physical function and global perceived change.

Ethics and dissemination

This protocol was approved by the Research Ethics Committee of the Trairi School of Health Sciences, Federal University of Rio Grande do Norte (Approval Number: 6.801.827), and it is in accordance with the Declaration of Helsinki for human research. Results will be published in peer-reviewed journals and presented at scientific events. This trial is registered in the Brazilian Clinical Trials Registry.

Non-invasive electrophysiological monitoring vs conventional monitoring during labour in a tertiary obstetric care centre in the Netherlands: study protocol of a cohort intervention random sampling study (NIEM-II study)

Introduction

Conventional cardiotocography (CTG) has been used extensively to monitor the fetal condition during labour. However, conventional non-invasive monitoring is limited by the difficulty of obtaining an adequate signal quality, particularly in the case of obese parturients. Furthermore, the rate of operative deliveries keeps rising despite the ability for conventional intrapartum monitoring. Electrophysiological monitoring is an alternative technique that has been developed over the past decades to improve signal quality. This non-invasive, transabdominal and wireless alternative measures fetal heart rate by fetal electrocardiography (NI-fECG), and uterine activity by electrohysterography (EHG). Both NI-fECG and EHG have been proven to be more accurate and reliable than conventional non-invasive methods and are less affected by maternal Body Mass Index. Nevertheless, it is still unknown whether electrophysiological intrapartum monitoring leads to better obstetric and neonatal outcomes. This study aims to investigate whether electrophysiological monitoring during labour affects the number of operative interventions compared with conventional monitoring during labour.

Methods and analysis

This is a single-centre cohort intervention random sampling study which will be performed in a tertiary obstetric care centre. In total, 3471 term pregnant women with a singleton fetus in cephalic position and indication for continuous fetal monitoring during labour will be included. Eligible women will be prospectively included in the cohort for conventional monitoring. From these women, 90.9% of women will be randomly sampled and will be offered electrophysiological monitoring. A historical cohort of an additional 2100 women who received conventional monitoring will be added to the conventional group. This historical cohort was collected between April 2019 and February 2023. The primary outcome will be the number of operative interventions during labour. Secondary outcome measures include maternal and neonatal outcomes, patient and healthcare professional perspectives and costs.

Introduction

As the opioid crisis continues, people who use drugs (PWUD) experience a disproportionate burden of both HIV and overdose, driven by increased injection-related HIV outbreaks and an opaque and rapidly evolving drug market, respectively. Pre-exposure prophylaxis (PrEP) for HIV and point-of-care drug checking services are underused yet potentially impactful interventions to address the harms of the opioid crisis. Implementing such interventions using known strategies to enhance client engagement and reduce access barriers, such as street outreach, mobile services and peer navigation, can optimise intervention and maximise their impact.

Methods and analysis

The Substance Checking Outreach and PrEP Engagement (SCOPE) Study is a non-randomised clinical trial evaluating the impact of the Check It intervention, a mobile community PrEP and drug checking intervention in Baltimore, Maryland, USA. SCOPE will recruit a cohort of 500 PWUD at risk for HIV through street-based recruitment methods. Cohort members will be followed semi-annually for 18 months. The primary study outcomes are engagement with the PrEP continuum of care and the number of non-fatal overdoses. We will use both random effects models and marginal structural models to estimate the effects of Check It on participant engagement on the PrEP continuum and the number of non-fatal overdoses over time.

Ethics and dissemination

Study procedures have been approved by the Johns Hopkins Bloomberg School of Public Health Institutional Review Board. Risks to participants are low, with the most serious risk being potential data confidentiality breaches. This risk was minimised through the use of secure data storage platforms with limited user access. Study findings will be disseminated through peer-reviewed manuscripts, academic presentations, and reports and fact sheets designed for lay audiences.
