OPtimising Treatment for MIld Systolic hypertension in the Elderly (OPTiMISE): protocol for a randomised controlled non-inferiority trial.

ABSTRACT: INTRODUCTION:Recent evidence suggests that larger blood pressure reductions and multiple antihypertensive drugs may be harmful in older people, particularly frail individuals with polypharmacy and multimorbidity. However, there is a lack of evidence to support deprescribing of antihypertensives, which limits the practice of medication reduction in routine clinical care. The aim of this trial is to examine whether antihypertensive medication reduction is possible in older patients without significant changes in blood pressure control at follow-up. METHODS AND ANALYSIS:This trial will use a primary care-based, open-label, randomised controlled trial design. A total of 540 participants will be recruited, aged ?80 years, with systolic blood pressure <150?mm Hg and receiving ?2?antihypertensive medications. Participants will have no compelling indication for medication continuation and will be considered to potentially benefit from medication reduction due to existing polypharmacy, comorbidity and frailty. Following a baseline appointment, individuals will be randomised to a strategy of medication reduction (intervention) with optional self-monitoring or usual care (control). Those in the intervention group will have one antihypertensive medication stopped. The primary outcome will be to determine if a reduction in medication can achieve a proportion of participants with clinically safe blood pressure levels at 12-week follow-up (defined as a systolic blood pressure <150?mm Hg), which is non-inferior (within 10%) to that achieved by the usual care group. Qualitative interviews will be used to understand the barriers and facilitators to medication reduction. The study will use economic modelling to predict the long-term effects of any observed changes in blood pressure and quality of life. ETHICS AND DISSEMINATION:The protocol, informed consent form, participant information sheet and all other participant facing material have been approved by the Research Ethics Committee (South Central-Oxford A; ref 16/SC/0628), Medicines and Healthcare products Regulatory Agency (ref 21584/0371/001-0001), host institution(s) and Health Research Authority. All research outputs will be published in peer-reviewed journals and presented at national and international conferences.

Project description:INTRODUCTION:Obesity represents a significant health burden, and WHO recognises the importance of preventing weight gain and subsequent development of obesity among adults who are within the healthy weight range. Women of reproductive age have demonstrated high rates of weight gain during pregnancy placing them at risk of becoming overweight or obese. We will evaluate the effects of dietary and physical activity advice on maternal, fetal and infant health outcomes, among pregnant women of normal body mass index (BMI). METHODS AND ANALYSIS:We will conduct a randomised controlled trial, consenting and randomising women with a live singleton pregnancy between 10+0 and 20+0 weeks and BMI 18.5-24.9?kg/m2 at first antenatal visit, from a tertiary maternity hospital. Women randomised to the Lifestyle Advice Group will receive three face-to-face sessions (two with a research dietitian and one with a trained research assistant) and three telephone calls over pregnancy, in which they will be provided with dietary and lifestyle advice and encouraged to make change using a SMART goals approach. Women randomised to the Standard Care Group will receive routine antenatal care. The primary outcome is infant birth weight >4?kg. Secondary outcomes will include adverse infant and maternal outcomes, maternal weight change, maternal diet and physical activity changes, maternal quality of life and emotional well-being, fetal growth and costs of healthcare. We will recruit 624 women to detect a reduction from 8.72% to 3.87% (alpha 0.05 (two-tailed); power 70%) in infants with birth weight >4?kg. Analyses will be intention to treat with estimates reported as relative risks and 95% CIs. ETHICS AND DISSEMINATION:Ethical approval has been obtained from the Women's and Children's Hospital ethics committee. Findings will be disseminated widely via journal publication and conference presentation(s), and participants informed of results. TRIAL REGISTRATION NUMBER:ACTRN12614000583640.

Project description:IntroductionMultimorbidity and polypharmacy are major risk factors for potentially inappropriate prescribing (eg, overprescribing and underprescribing), and systematic medication reviews are complex and time consuming. In this trial, the investigators aim to determine if a systematic software-based medication review improves medication appropriateness more than standard care in older, multimorbid patients with polypharmacy.Methods and analysisOptimising PharmacoTherapy In the multimorbid elderly in primary CAre is a cluster randomised controlled trial that will include outpatients from the Swiss primary care setting, aged ≥65 years with ≥three chronic medical conditions and concurrent use of ≥five chronic medications. Patients treated by the same general practitioner (GP) constitute a cluster, and clusters are randomised 1:1 to either a standard care sham intervention, in which the GP discusses with the patient if the medication list is complete, or a systematic medication review intervention based on the use of the 'Systematic Tool to Reduce Inappropriate Prescribing'-Assistant (STRIPA). STRIPA is a web-based clinical decision support system that helps customise medication reviews. It is based on the validated 'Screening Tool of Older Person's Prescriptions' (STOPP) and 'Screening Tool to Alert doctors to Right Treatment' (START) criteria to detect potentially inappropriate prescribing. The trial's follow-up period is 12 months. Outcomes will be assessed at baseline, 6 and 12 months. The primary endpoint is medication appropriateness, as measured jointly by the change in the Medication Appropriateness Index (MAI) and Assessment of Underutilisation (AOU). Secondary endpoints include the degree of polypharmacy, overprescribing and underprescribing, the number of falls and fractures, quality of life, the amount of formal and informal care received by patients, survival, patients' quality adjusted life years, patients' medical costs, cost-effectiveness of the intervention, percentage of recommendations accepted by GPs, percentage of recommendation rejected by GPs and patients' willingness to have medications deprescribed.Ethics and disseminationThe ethics committee of the canton of Bern in Switzerland approved the trial protocol. The results of this trial will be published in a peer-reviewed journal.Main fundingSwiss National Science Foundation, National Research Programme (NRP 74) 'Smarter Healthcare'.Trial registration numbersClinicaltrials.gov (NCT03724539), KOFAM (Swiss national portal) (SNCTP000003060), Universal Trial Number (U1111-1226-8013).

Project description:BackgroundThe reporting of randomised controlled non-inferiority (NI) drug trials is poor with less than 50% of published trials reporting a justification of the NI margin. This is despite the introduction of the Consolidated Standards of Reporting Trials (CONSORT) extension on reporting of NI and equivalence in randomised trials. It is critical to set the appropriate NI margin as this choice dictates the conclusions of the trial. Methods to estimate the margin are heterogeneous but generally based on clinical judgement and statistical reasoning, and hence tailored to each clinical situation. Yet an appraisal of NI in clinical trials has not been undertaken. Therefore the aim of this systematic review is to assess the reporting and methodological quality of defining the NI margin. Surgical NI trials have been chosen as our prototype to assess this.MethodsWe will conduct a systematic review of published randomised controlled trials in abdominal surgery that use an NI design. Key eligibility criteria will be: surgical intervention in at least one trial arm; adult patients and a sample size of 100 or more. Ovid MEDLINE, EMBASE and the Cochrane Central Register of Controlled Trials will be searched from inception until the date of the search. Identified studies will be assessed for reporting according to the CONSORT recommendations. The outcomes are the description of the methods for defining the NI margin, and the robustness of the NI margin estimation. The latter will be based on simulations using alternative assumptions for model parameters. The results of the simulation will be compared with the trial authors' conclusions.Anticipated resultsThe review will describe and appraise the design and reporting of surgical NI trials including shortcomings thereof and allow a comparison with pharmaceutical trials. These findings will inform researchers on the appropriate design and pitfalls when conducting surgical randomised controlled trials with an NI design and promote thorough and standardised reporting of study findings.Ethics and disseminationEthical approval is not required and any changes to the protocol will be communicated via the registration platform. The final manuscript will be submitted to a journal for publication and the findings will be disseminated through conference presentations to inform researchers and the public.

Project description:BackgroundThe majority of people with dementia are cared for by their family members. However, family carers are often unprepared for their caring roles, receiving less education and support compared with professional carers. The consequences are their reduced mental and physical health and wellbeing, and that of care recipients. This study protocol introduces the 'Partnership in iSupport program' that includes five interventional components: managing transitions, managing dementia progression, psychoeducation, carer support group and feedback on services. This health services research is built on family carer and dementia care service provider partnerships. The aims of the study are to evaluate the effectiveness, cost-effectiveness and family carers' experiences in the program.MethodsA multicentre randomised controlled trial will be conducted with family carers of people living with dementia from two tertiary hospitals and two community aged care providers across three Australian states. The estimated sample size is 185 family carers. They will be randomly assigned to either the intervention group or the usual care group. Outcomes are measurable improvements in quality of life for carers and people with dementia, caregiving self-efficacy, social support, dementia related symptoms, and health service use for carers and their care recipients. Data will be collected at three time points: baseline, 6 months and 12 months post-initiation of the intervention.DiscussionThis is the first large randomised controlled trial of a complex intervention on health and social care services with carers of people living with dementia in real-world practice across hospital and community aged care settings in three Australian states to ascertain the effectiveness, cost-effectiveness and carers' experiences of the innovative program. We expect that this study will address gaps in supporting dementia carers in health and social care systems while generating new knowledge of the mechanisms of change in the systems. Findings will strengthen proactive health management for both people living with dementia and their carers by embedding, scaling up and sustaining the 'Partnership in iSupport program' in the health and social care systems.Trial registrationThe Australian New Zealand Clinical Trials Registry (ANZCTR).

Project description:IntroductionEpilepsy is a chronic condition requiring consistent follow-up aimed at seizure control, and monitoring of anti-seizure medication (ASM) levels and side effects. Telemedicine (TM) offers invaluable support to patient follow-up, guaranteeing the prompt availability of a team of experts for persons with epilepsy (PWE) widely distributed across the country. Although many health institutions have endorsed the use of TM, robust data on effectiveness, safety and costs of TM applied to epilepsy are lacking. TELEmedicine for EPIlepsy Care (TELE-EPIC) will evaluate the effectiveness of video consultation (VC) via TM compared with usual care (UC) for the monitoring of PWE (TELE-EPIC_RCT). Moreover, TELE-EPIC will apply an innovative Volumetric Absorptive Microsampling (VAMS) device for quantitation of ASM through finger prick blood sampling as an alternative to venipuncture sampling (TELE-EPIC_VAMS).Methods and analysisTELE-EPIC_RCT is a multicentre, open, pragmatic two-arm randomised controlled trial prospectively including adult and paediatric outpatients with established diagnosis of epilepsy consecutively attending the Epilepsy Centres of Bologna and Rome, respectively. The primary outcome is the non-inferiority of VC on seizure control compared with UC after an 18-month follow-up. Secondary outcomes are adherence to treatment, ASM-related adverse events, quality of life, mood disorders, patient and caregiver satisfaction, safety and costs. TELE-EPIC_VAMS is a cross-validation study for blood ASM quantitation through a novel, VAMS-based device, comparing (1) VAMS versus plasma samples (reference standard method); and (2) nurse-collected versus self-collected blood by VAMS device.Ethics and disseminationThe study has been approved by the local ethics committee (349-2019-SPER-AUSLBO). Complete information about the state of project, relevant events and results will be regularly updated on the project's webpage on ClinicalTrials.gov. The project's results and data on the potential impact of TM in epilepsy will be disseminated on social media. A closeout meeting will be convened for the communication and dissemination of the project, highlighting its main achievements and impacts.Trial registration numberNCT04496310.

Project description:IntroductionPulsed electromagnetic field (PEMF) is an available treatment for knee osteoarthritis (KOA), which is the most common cause of pain and disability. Nonetheless, whether the clinical effects are like that of most used drugs is unclear. Thus, this study aims to determine the effect of PEMF on pain relief by comparing them with the positive drug (celecoxib). Furthermore, this clinical trial aims to evaluate the effect of PEMF on function and quality of life with a long-term follow-up.Methods and analysisThis two-armed, non-inferiority, randomised, controlled trial will be conducted in the outpatient physiatry/physiotherapy clinic or inpatient ward of 17 hospitals in China. A total of 428 individuals will be included who are more than 40 years of age with diagnosed KOA. The participants will be randomly allocated to the PEMF group: receiving a 6-week PEMF (15 Hz, 30 mT) at a frequency of 40 min per day, 5 days per week plus sham drug (n=214), or drug group: receiving a 6-week celecoxib 200 mg combined with sham PEMF (n=214). Clinical outcomes will be measured at baseline (T0), mid-term of intervention (T1), post-intervention (T2), 10, 18 and 30 weeks (T3-5) of follow-up after randomisation. The primary outcome will be the Western Ontario and McMaster Universities (WOMAC) pain index. The secondary outcomes will be WOMAC function and stiffness, pain measured by numerical rating score, quality of life, 6-minute walk test, pain catastrophising scale and responder index.Ethics and disseminationThe trial is performed following the Declaration of Helsinki. The study protocol and consent form have been approved by the Ethics Committee on Biomedical Research of West China Hospital of Sichuan University (#2021-220). All patients will give informed consent before participation and the trial is initiated after approval. Results of this trial will be disseminated through publication in peer-reviewed journals.Trial registration numberChiCTR2100052131.

Project description:ObjectiveTo determine whether ultraviolet B phototherapy at home is equally safe and equally effective as ultraviolet B phototherapy in an outpatient setting for patients with psoriasis.DesignPragmatic multicentre single blind randomised clinical trial (PLUTO study).SettingDermatology departments of 14 hospitals in the Netherlands.Participants196 patients with psoriasis who were clinically eligible for narrowband (TL-01) ultraviolet B phototherapy. The first 105 consecutive patients were also followed for one year after therapy.InterventionUltraviolet B phototherapy at home using a TL-01 home phototherapy unit compared with standard narrowband ultraviolet B phototherapy in an outpatient setting. Both therapies were done in a setting reflecting routine daily practice in the Netherlands.Main outcome measuresThe main outcome measure was effectiveness as measured by the proportion of patients with a 50% or more reduction of the baseline psoriasis area and severity index (PASI) or self administered psoriasis area and severity index (SAPASI), called the PASI 50 and SAPASI 50 (relevant treatment effect). Another outcome of effectiveness was the percentage reduction in median scores on the PASI as well as SAPASI. Also the proportions of patients reaching the PASI 75 and SAPASI 75 (successful treatment effect), and the PASI 90 and SAPASI 90 (almost complete clearance) were calculated. Other secondary outcomes were quality of life (SF-36, psoriasis disability index), burden of treatment (questionnaire), patients' preferences and satisfaction (questionnaire), and dosimetry and short term side effects (diary).Results82% of the patients treated at home compared with 79% of the patients treated in an outpatient setting reached the SAPASI 50 (difference 2.8%, 95% confidence interval -8.6% to 14.2%), and 70% compared with 73% reached the PASI 50 (-2.3%, -15.7% to 11.1%). For patients treated at home the median SAPASI score decreased 82% (from 6.7 to 1.2) and the median PASI score decreased 74% (from 8.4 to 2.2), compared with 79% (from 7.0 to 1.4) and 70% (from 7.0 to 2.1) for patients treated in an outpatient setting. Treatment effect as defined by the mean decline in PASI and SAPASI scores was significant (P<0.001) and similar across groups (P>0.3). Total cumulative doses of ultraviolet B light were similar (51.5 v 46.1 J/cm(2), difference 5.4, 95% confidence interval -5.2 to 16.0), and the occurrence of short term side effects did not differ. The burden of undergoing ultraviolet B phototherapy was significantly lower for patients treated at home (differences 1.23 to 3.01, all P</=0.001). Quality of life increased equally regardless of treatment, but patients treated at home more often rated their experience with the therapy as "excellent" (42%, 38/90) compared with patients treated in the outpatient department (23%, 20/88; P=0.001).ConclusionUltraviolet B phototherapy administered at home is equally safe and equally effective, both clinically and for quality of life, as ultraviolet B phototherapy administered in an outpatient setting. Furthermore, ultraviolet B phototherapy at home resulted in a lower burden of treatment and led to greater patients' satisfaction.
