Improving Primary Care After Stroke (IPCAS) randomised controlled trial: protocol for a multidimensional process evaluation.

ABSTRACT: INTRODUCTION:Primary care interventions are often multicomponent, with several targets (eg, patients and healthcare professionals). Improving Primary Care After Stroke (IPCAS) is a novel primary care-based model of long-term stroke care involving a review of stroke-related needs, a self-management programme, a direct point of contact in general practice, enhanced communication between care services, and a directory of national and local community services, currently being evaluated in a cluster randomised controlled trial (RCT). Informed by Medical Research Council guidance for complex interventions and the Behaviour Change Consortium fidelity framework, this protocol outlines the process evaluation of IPCAS within this RCT. The process evaluation aimed to explore how the intervention was delivered in context and how participants engaged with the intervention. METHODS AND ANALYSIS:Mixed methods will be used: (1) design: intervention content will be compared with 'usual care'; (2) training: intervention training sessions will be audio/video-recorded where feasible; (3) delivery: healthcare professional self-reports, audio recordings of intervention delivery and observations of My Life After Stroke course (10% of reviews and sessions) will be coded separately; semistructured interviews will be conducted with a purposive sample of healthcare professionals; (4) receipt and (5) enactment: where available, structured stroke review records will be analysed quantitatively; semistructured interviews will be conducted with a purposive sample of study participants. Self-reports, observations and audio/video recordings will be coded and scored using specifically developed checklists. Semistructured interviews will be analysed thematically. Data will be analysed iteratively, independent of primary endpoint analysis. ETHICS AND DISSEMINATION:Favourable ethical opinion was gained from Yorkshire & The Humber-Bradford Leeds NHS Research Ethics Committee (19 December 2017, 17/YH/0441). Study results will be published in a peer-reviewed journal and presented at relevant conferences. TRIAL REGISTRATION NUMBER:NCT03353519; Pre-results.

Project description:INTRODUCTION:Survival after stroke is improving, leading to increased demand on primary care and community services to meet the long-term care needs of people living with stroke. No formal primary care-based holistic model of care with clinical trial evidence exists to support stroke survivors living in the community, and stroke survivors report that many of their needs are not being met. We have developed a multifactorial primary care model to address these longer term needs. We aim to evaluate the clinical and cost-effectiveness of this new model of primary care for stroke survivors compared with standard care. METHODS AND ANALYSIS:Improving Primary Care After Stroke (IPCAS) is a two-arm cluster-randomised controlled trial with general practice as the unit of randomisation. People on the stroke registers of general practices will be invited to participate. One arm will receive the IPCAS model of care including a structured review using a checklist; a self-management programme; enhanced communication pathways between primary care and specialist services; and direct point of contact for patients. The other arm will receive usual care. We aim to recruit 920 people with stroke registered with 46 general practices. The primary endpoint is two subscales (emotion and handicap) of the Stroke Impact Scale (SIS) as coprimary outcomes at 12 months (adjusted for baseline). Secondary outcomes include: SIS Short Form, EuroQol EQ-5D-5L, ICEpop CAPability measure for Adults, Southampton Stroke Self-management Questionnaire, Health Literacy Questionnaire and medication use. Cost-effectiveness of the new model will be determined in a within-trial economic evaluation. ETHICS AND DISSEMINATION:Favourable ethical opinion was gained from Yorkshire and the Humber-Bradford Leeds NHS Research Ethics Committee. Approval to start was given by the Health Research Authority prior to recruitment of participants at any NHS site. Data will be presented at national and international conferences and published in peer-reviewed journals. Patient and public involvement helped develop the dissemination plan. TRIAL REGISTRATION NUMBER:NCT03353519.

Project description:IntroductionCaring for stroke survivors creates high levels of care burden among family caregivers. Previous initiatives at alleviating the care burden have been unsuccessful. The proposed study aims to evaluate the effect of a tailored multidimensional intervention on the care burden among family caregivers of stroke survivors. Based on the perceived needs of family caregivers, this intervention takes into account scientific recommendations to combine three different approaches: skill-building, psychoeducation and peer support.Methods and analysisUsing a prospective, randomised, open-label, parallel-group design, 110 family caregivers will be enrolled from Dakahlia Governorate, Egypt between December 2019 and May 2020, and randomly assigned to either the intervention group or the control group. The tailored multidimensional intervention will be administered for 6 months, including three home visits, six home-based telephone calls and one peer support session. The primary outcome is the care burden as measured using the Zarit Burden Interview. Secondary outcomes include changes in the family caregivers' perceived needs (Family Needs Questionnaire-Revised), coping strategies (Brief-Coping Orientation to Problems Experienced) and quality of life (WHO Quality of Life-BREF). Outcomes evaluation will be conducted at baseline (T0), month 3 (T1) and month 6 (T2). Independent t-test will be performed to compare the mean values of study variables between the two groups at both T1 and T2. After adjusting for confounding variables, analysis of covariance will be used to assess the effect of the intervention. In addition, repeated measures analysis of variance will be conducted to assess changes in effect over time.Ethics and disseminationThis study was approved by the Research Ethics Committee of the Faculty of Nursing, Mansoura University, Mansoura, Egypt (P.0195). The results will be published in a scientific peer-reviewed journal, and findings will be disseminated at the local and international levels.Trial registration numberNCT04211662.

Project description:IntroductionBrain-related visual impairments, also known as cerebral visual impairment (CVI), are related to damage or poor function in the vision-related areas of the brain. There is broad agreement that CVI is an appropriate term to describe visual impairments that are not accounted by disorders of the eye or optic nerve, but differences remain as to which impairments can be included in this term. The CVI project is a programme of work that includes the development of a complex intervention to share knowledge with teachers, so that they can make both targeted and universal changes to support children with CVI. A feasibility study for a cluster-randomised controlled trial to evaluate this intervention is underway. This paper describes the protocol for an accompanying process evaluation to explore how the intervention is implemented and provide context for the interpretation of the feasibility trial outcomes.Methods and analysisA logic model has been developed to guide data collection. Both qualitative and quantitative data will be collected to assess the feasibility and acceptability of the intervention, the study design and explore how any changes that occur are brought about. Interviews with key primary school staff and parents will investigate responses to the intervention and trial processes. Surveys will collect data on intervention implementation and knowledge of CVI. Photographs of classroom walls will document any changes to visual clutter and document analysis will look for changes to school special educational needs and disability (SEND) policies.Ethics and disseminationEthical approval was granted by the University of Bristol Faculty of Health Sciences Ethics Committee. Findings will contribute to the development of a full-scale cluster-randomised controlled trial to assess the effectiveness of the intervention with adequate statistical power. The results will also support the refinement of the intervention and its underlying theory.

Project description:IntroductionUnmet needs in patients with cancer and their carers are common but poorly identified and addressed. The Needs Assessment Tool-Cancer (NAT-C) is a structured consultation guide to identify and triage patient and carer unmet needs. The NAT-C is validated, but its effectiveness in reducing unmet patient and carer needs in primary care is unknown.Methods and analysisCluster randomised controlled trial with internal pilot and embedded process evaluation to test the clinical and cost effectiveness of the NAT-C in primary care for people with active cancer in reducing unmet patient and carer need, compared with usual care. We will recruit 1080 patients with active cancer (and carers if relevant) from 54 general practices in England.Participating practices will be randomised 1:1 to either deliver an NAT-guided clinical consultation plus usual care or to usual care alone. Consenting participants with active cancer and their carers (if nominated) will be asked to complete study questionnaires at baseline, 1 and 3 months for all, 6 months except for those recruited outside of the last 3 months of recruitment, and attend an NAT-C appointment if allocated to an intervention practice. An internal pilot will assess: site and participant recruitment, intervention uptake and follow-up rates. The primary outcome, the proportion of patients with an unmet need on the Supportive Care Needs Survey Short Form 34 at 3 months postregistration, will be analysed using a multilevel logistic regression. Mixed-methods process evaluation informed by Normalisation Process Theory will use quantitative survey and interview data from clinicians and key stakeholders in cancer care to develop an implementation strategy for nationwide rollout of the NAT-C if the intervention is cost-effective.Ethics and disseminationEthical approval from London-Surrey REC (20/LO/0312). Results will be peer-reviewed, published and made available to research participants.Trial registration numberISRCTN15497400.

Project description:ObjectiveTo investigate (i) how the SLIMMER intervention was delivered and received in Dutch primary health care and (ii) how this could explain intervention effectiveness.DesignA randomised controlled trial was conducted and subjects were randomly allocated to the intervention (10-month combined dietary and physical activity intervention) or the control group. A process evaluation including quantitative and qualitative methods was conducted. Data on process indicators (recruitment, reach, dose received, acceptability, implementation integrity and applicability) were collected via semi-structured interviews with health-care professionals (n 45) and intervention participant questionnaires (n 155).SettingSLIMMER was implemented in Dutch primary health care in twenty-five general practices, eleven dietitians, nine physiotherapist practices and fifteen sports clubs.SubjectsSubjects at increased risk of developing type 2 diabetes were included.ResultsIt was possible to recruit the intended high-risk population (response rate 54 %) and the SLIMMER intervention was very well received by both participants and health-care professionals (mean acceptability rating of 82 and 80, respectively). The intervention programme was to a large extent implemented as planned and was applicable in Dutch primary health care. Higher dose received and participant acceptability were related to improved health outcomes and dietary behaviour, but not to physical activity behaviour.ConclusionsThe present study showed that it is feasible to implement a diabetes prevention intervention in Dutch primary health care. Higher dose received and participant acceptability were associated with improved health outcomes and dietary behaviour. Using an extensive process evaluation plan to gain insight into how an intervention is delivered and received is a valuable way of identifying intervention components that contribute to implementation integrity and effective prevention of type 2 diabetes in primary health care.

Project description:BackgroundLow physical activity is a major public health problem. New cost-effective approaches that stimulate meaningful long-term changes in physical activity are required, especially within primary care settings. It is becoming clear that there are various dimensions to physical activity with independent health benefits. Advances in technology mean that it is now possible to generate multidimensional physical activity 'profiles' that provide a more complete representation of physical activity and offer a variety of options that can be tailored to the individual. Mi-PACT is a randomised controlled trial designed to examine whether personalised multidimensional physical activity feedback and self-monitoring alongside trainer-supportive sessions increases physical activity and improves health outcomes in at-risk men and women.Methods/designWe aim to recruit 216 patients from within primary care aged 40 to 70 years and at medium or high risk of cardiovascular disease and/or type II diabetes mellitus. Adopting an unequal allocation ratio (intervention: control) of 2:1, participants will be randomised to one of two groups, usual care or the intervention. The control group will receive usual care from their general practitioner (GP) and standardised messages about physical activity for health. The intervention group will receive physical activity monitors and access to a web-based platform for a 3-month period to enable self-monitoring and the provision of personalised feedback regarding the multidimensional nature of physical activity. In addition, this technology-enabled feedback will be discussed with participants on 5 occasions during supportive one-to-one coaching sessions across the 3-month intervention. The primary outcome measure is physical activity, which will be directly assessed using activity monitors for a 7-day period at baseline, post intervention and at 12 months. Secondary measures (at these time-points) include weight loss, fat mass, and markers of metabolic control, motivation and well-being.DiscussionResults from this study will provide insight into the effects of integrated physical activity profiling and self-monitoring combined with in-person support on physical activity and health outcomes in patients at risk of future chronic disease.Trial registrationISRCTN18008011 Trial registration date: 31 July 2013.

Project description:Background: Multimorbidity (the presence of two or more chronic conditions) is associated with poorer health outcomes, particularly for patients with significant polypharmacy (?15 medications), due to the higher risk of adverse events and drug interactions. The SPPiRE study will assess the effectiveness of a complex intervention to support general practitioners (GPs) to reduce potentially inappropriate prescribing and consider deprescribing in older people with multimorbidity and significant polypharmacy. The aim of the SPPiRE process evaluation is to understand how and why the intervention is effective or ineffective and to explore the potential for system wide implementation of the intervention using the Medical Research Council general themes of context, implementation and mechanism of impact. Methods: The SPPiRE study is a clustered randomised controlled trial (RCT), aiming to recruit 55 general practices and 400 patients (?65 years) on ?15 medications throughout the Republic of Ireland. This mixed-methods process evaluation of the SPPiRE study will integrate both quantitative and qualitative data. Quantitative data will be collected on use of the intervention elements and from GP questionnaires. Qualitative data will be collected from semi-structured telephone interviews with all intervention GPs and a purposeful sample of patients from intervention practices. The topic guide will explore barriers and facilitators to participation and implementation of the intervention. Quantitative data will be analysed using descriptive statistics. Interviews will be transcribed and analysed using thematic analysis. Quantitative and qualitative data will be then be integrated. Discussion: The SPPiRE cluster RCT will provide evidence regarding the effectiveness and practicability of delivering a structured medication review in reducing polypharmacy and potentially inappropriate prescribing for patients with multimorbidity. This process evaluation will provide information on how the intervention was implemented, how it was or was not effective and the potential for a system wide implementation.
