Development of complex interventions in stroke care: a systematic review

Music Upper Limb Therapy - Integrated (MULT-I) supports a positive transformation in sense of self post stroke: a thematic analysis

PURPOSE

To understand how the experience of Music Upper Limb Therapy - Integrated (MULT-I) interconnects with the experience of stroke.

METHODS

Thematic analysis of semi-structured interviews and video-recorded MULT-I sessions from a larger mixed-methods study. Thirty adults with post-stroke hemiparesis completed pre-intervention interviews, of whom fifteen participated in MULT-I. Thirteen of the participants in MULT-I completed post-intervention interviews.

RESULTS

The experience of stroke was characterized by five themes: (1) sudden loss of functional abilities, (2) disrupted participation, (3) desire for independence, (4) emotional distress and the need for support, and (5) difficulty negotiating changes in sense of self. The experience of MULT-I was characterized by three themes: (1) MULT-I activated movement and empowered personal choice, (2) MULT-I created a safe place to process emotional distress and take on challenges, and (3) MULT-I fostered a sense of belonging and a positive transformation in sense of self. These themes combined create a framework which illustrates the process by which MULT-I addressed each challenge described by survivors of stroke, facilitating a positive transformation in sense of self.

CONCLUSION

MULT-I promotes physical, emotional, and social wellbeing following a stroke. This integrated approach supports a positive transformation in sense of self. These findings have implications for improving psychosocial well-being post stroke.

Reducing risk behaviours after stroke: An overview of reviews interrogating primary study data using the Theoretical Domains Framework

BACKGROUND

Lifestyle changes, in addition to preventive medications, optimise stroke secondary prevention. Evidence from systematic reviews support behaviour-change interventions post-stroke to address lifestyle-related risk. However, understanding of the theory-driven mediators that affect behaviour-change post-stroke is lacking.

METHODS

Electronic databases MEDLINE, Embase, Epistemonikos and Cochrane Library of Systematic Reviews were searched to March 2023 for systematic reviews addressing behaviour-change after stroke. Primary studies from identified systematic reviews were interrogated for evidence supporting theoretically-grounded interventions. Data were synthesized in new meta-analyses examining behaviour-change domains of the Theoretical Domains Framework (TDF) and secondary prevention outcomes.

RESULTS

From 71 identified SRs, 246 primary studies were screened. Only 19 trials (N = 2530 participants) were identified that employed theoretically-grounded interventions and measured associated mediators for behaviour-change. Identified mediators mapped to 5 of 14 possible TDF domains. Trial follow-up ranged between 1-12 months and no studies addressed primary outcomes of recurrent stroke or cardiovascular mortality and/or morbidity. Lifestyle interventions targeting mediators mapped to the TDF Knowledge domain may improve the likelihood of medication adherence (OR 6.08 [2.79, 13.26], I2 = 0%); physical activity participation (OR 2.97 [1.73, 5.12], I2 = 0%) and smoking cessation (OR 10.37 [3.22, 33.39], I2 = 20%) post-stroke, supported by low certainty evidence; Lifestyle interventions targeting mediators mapping to both TDF domains of Knowledge and Beliefs about Consequences may improve medication adherence post-stroke (SMD 0.36 [0.07, 0.64], I2 = 13%, very low certainty evidence); Lifestyle interventions targeting mediators mapped to Beliefs about Capabilities and Emotions domains may modulate low mood post-stroke (SMD -0.70 [-1.28, -0.12], I2 = 81%, low certainty evidence).

CONCLUSION

Limited theory-based research and use of behaviour-change mediators exists within stroke secondary prevention trials. Knowledge, Beliefs about Consequences, and Emotions are the domains which positively influence risk-reducing behaviours post-stroke. Behaviour-change interventions should include these evidence-based constructs known to be effective. Future trials should address cardiovascular outcomes and ensure adequate follow-up time.

Co-design for stroke intervention development: Results of a scoping review

BACKGROUND

Co-design methodology seeks to actively engage end-users in developing interventions. It is increasingly used to design stroke interventions; however, limited guidance exists, particularly with/for individuals with stroke who have diverse cognitive, physical and functional abilities. Thus, we describe 1) the extent of existing research that has used co-design for stroke intervention development and 2) how co-design has been used to develop stroke interventions among studies that explicitly used co-design, including the rationale, types of co-designed stroke interventions, participants involved, research methodologies/approaches, methods of incorporating end-users in the research, co-design limitations, challenges and potential strategies reported by researchers.

MATERIALS AND METHODS

A scoping review informed by Joanna Briggs Institute and Arksey & O'Malley methodology was conducted by searching nine databases on December 21, 2022, to locate English-language literature that used co-design to develop a stroke intervention. Additional data sources were identified through a hand search. Data sources were de-duplicated, and two research team members reviewed their titles, abstracts and full text to ensure they met the inclusion criteria. Data relating to the research objectives were extracted, analyzed, and reported numerically and descriptively.

RESULTS

Data sources used co-design for stroke intervention development with (n = 89) and without (n = 139) explicitly using the term 'co-design.' Among studies explicitly using co-design, it was commonly used to understand end-user needs and generate new ideas. Many co-designed interventions were technology-based (65%), and 48% were for physical rehabilitation or activity-based. Co-design was commonly conducted with multiple participants (82%; e.g., individuals with stroke, family members/caregivers and clinicians) and used various methods to engage end-users, including focus groups and workshops. Limitations, challenges and potential strategies for recruitment, participant-engagement, contextual and logistical and ethics of co-designed interventions were described.

CONCLUSIONS

Given the increasing popularity of co-design as a methodology for developing stroke interventions internationally, these findings can inform future co-designed studies.

Interventions for the uptake of evidence-based recommendations in acute stroke settings

BACKGROUND

There is a growing body of research evidence to guide acute stroke care. Receiving care in a stroke unit improves access to recommended evidence-based therapies and patient outcomes. However, even in stroke units, evidence-based recommendations are inconsistently delivered by healthcare workers to patients with stroke. Implementation interventions are strategies designed to improve the delivery of evidence-based care.

OBJECTIVES

To assess the effects of implementation interventions (compared to no intervention or another implementation intervention) on adherence to evidence-based recommendations by health professionals working in acute stroke units. Secondary objectives were to assess factors that may modify the effect of these interventions, and to determine if single or multifaceted strategies are more effective in increasing adherence with evidence-based recommendations.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, CINAHL, Joanna Briggs Institute and ProQuest databases to 13 April 2022. We searched the grey literature and trial registries and reviewed reference lists of all included studies, relevant systematic reviews and primary studies; contacted corresponding authors of relevant studies and conducted forward citation searching of the included studies. There were no restrictions on language and publication date.

SELECTION CRITERIA

We included randomised trials and cluster-randomised trials. Participants were health professionals providing care to patients in acute stroke units; implementation interventions (i.e. strategies to improve delivery of evidence-based care) were compared to no intervention or another implementation intervention. We included studies only if they reported on our primary outcome which was quality of care, as measured by adherence to evidence-based recommendations, in order to address the review aim.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected studies for inclusion, extracted data and assessed risk of bias and certainty of evidence using GRADE. We compared single implementation interventions to no intervention, multifaceted implementation interventions to no intervention, multifaceted implementation interventions compared to single implementation interventions and multifaceted implementation interventions to another multifaceted intervention. Our primary outcome was adherence to evidence-based recommendations.

MAIN RESULTS

We included seven cluster-randomised trials with 42,489 patient participants from 129 hospitals, conducted in Australia, the UK, China, and the Netherlands. Health professional participants (numbers not specified) included nursing, medical and allied health professionals. Interventions in all studies included implementation strategies targeting healthcare workers; three studies included delivery arrangements, no studies used financial arrangements or governance arrangements. Five trials compared a multifaceted implementation intervention to no intervention, two trials compared one multifaceted implementation intervention to another multifaceted implementation intervention. No included studies compared a single implementation intervention to no intervention or to a multifaceted implementation intervention. Quality of care outcomes (proportions of patients receiving evidence-based care) were included in all included studies. All studies had low risks of selection bias and reporting bias, but high risk of performance bias. Three studies had high risks of bias from non-blinding of outcome assessors or due to analyses used. We are uncertain whether a multifaceted implementation intervention leads to any change in adherence to evidence-based recommendations compared with no intervention (risk ratio (RR) 1.73; 95% confidence interval (CI) 0.83 to 3.61; 4 trials; 76 clusters; 2144 participants, I2 =92%, very low-certainty evidence). Looking at two specific processes of care, multifaceted implementation interventions compared to no intervention probably lead to little or no difference in the proportion of patients with ischaemic stroke who received thrombolysis (RR 1.14, 95% CI 0.94 to 1.37, 2 trials; 32 clusters; 1228 participants, moderate-certainty evidence), but probably do increase the proportion of patients who receive a swallow screen within 24 hours of admission (RR 6.76, 95% CI 4.44 to 10.76; 1 trial; 19 clusters; 1,804 participants; moderate-certainty evidence). Multifaceted implementation interventions probably make little or no difference in reducing the risk of death, disability or dependency compared to no intervention (RR 0.93, 95% CI 0.85 to 1.02; 3 trials; 51 clusters ; 1228 participants; moderate-certainty evidence), and probably make little or no difference to hospital length of stay compared with no intervention (difference in absolute change 1.5 days; 95% CI -0.5 to 3.5; 1 trial; 19 clusters; 1804 participants; moderate-certainty evidence). We do not know if a multifaceted implementation intervention compared to no intervention result in changes to resource use or health professionals' knowledge because no included studies collected these outcomes.

AUTHORS' CONCLUSIONS

We are uncertain whether a multifaceted implementation intervention compared to no intervention improves adherence to evidence-based recommendations in acute stroke settings, because the certainty of evidence is very low.

Scoping review protocol of the use of codesign methods in stroke intervention development

INTRODUCTION

Codesign is an emerging research method to enhance intervention development by actively engaging non-researchers (eg, people who have had a stroke, caregivers and clinicians) in research. The involvement of non-researchers in research is becoming increasingly popular within health studies as it may produce more relevant and effective findings. The stroke population commonly exhibits challenges such as aphasia and cognitive changes that may limit their participation in codesign. However, the use of codesign within the stroke literature has not been comprehensively reviewed. This scoping review will determine: (1) what is the extent, range and nature of stroke research that has used codesign methods? (2) What codesign methods have been used to develop stroke interventions? (3) What considerations for codesigning interventions with people who have stroke are not captured in the findings?

METHODS AND ANALYSIS

This is a protocol for a scoping review to identify the literature relating to stroke, and codesign will be conducted on OVID Medline, OVID Embase, OVID PsychINFO, EBSCO CINAHL, the Cochrane Library, Scopus, PEDro-Physiotherapy Evidence Database and Global Index Medicus. Studies of any design and publication date will be included. Title and abstract and full-text review will be conducted independently by two reviewers. Data will be extracted, collated and then summarised descriptively using quantitative (eg, numerical descriptions) and qualitative (eg, textual descriptions) methods. Numerical summaries will map the extent (eg, number of studies), range (eg, types of studies) and nature (eg, types of interventions developed) of the literature on this topic. A thematic analysis will provide insights into the codesign methods (eg, activities, non-researchers), including heterogeneity across and within studies.

ETHICS AND DISSEMINATION

This review protocol does not require ethics approval as data has not been collected/analysed. The findings will highlight opportunities and recommendations to inform future codesign research in stroke and other populations who exhibit similar challenges/disabilities, and they will be disseminated via publications, presentations and stakeholder meetings.

Capability, opportunity, motivation, and social participation after stroke

BACKGROUND

Stroke survivors report limited social participation, despite it being an important rehabilitation outcome. Interdisciplinary interventions for increasing social participation amongst stroke survivors lack theoretical guidance and evidence-based approaches. The Behavior Change Wheel (BCW) theorizes that capability, opportunity, and motivation contribute to behavior change.

OBJECTIVES

This study applied the BCW to understand the relationship between social participation and stroke survivors' capability, opportunity, and motivation.

METHODS

In this cross-sectional study, we recruited 30 community-dwelling adult stroke survivors. Assessments explored the frequency and satisfaction of social participation; physical and psychological capability; environmental accessibility and social opportunity; and motivation. A linear regression analysis was done.

RESULTS

Motivation (R² change = 29.3%, ß = 0.55) and environmental opportunity (R² change = 11%, ß = 0.39) were statistically significant predictors of social participation frequency. Motivation (R² change = 36.9%, ß = 0.61) was the only statistically significant predictor of satisfaction with social performance.

CONCLUSIONS

Motivation and environmental accessibility are statistically significant independent predictors of frequency of social participation after stroke. Motivation is the strongest predictor of satisfaction with social participation. Clinicians may support stroke survivors to promote social participation using approaches that increase motivation and environmental accessibility. Development of such theoretically sound interventions may be guided by the BCW.

Scientific basis and active ingredients of current therapeutic interventions for stroke rehabilitation

Background: Despite tremendous advances in the treatment and management of stroke, restoring motor and functional outcomes after stroke continues to be a major clinical challenge. Given the wide range of approaches used in motor rehabilitation, several commentaries have highlighted the lack of a clear scientific basis for different interventions as one critical factor that has led to suboptimal study outcomes. Objective: To understand the content of current therapeutic interventions in terms of their active ingredients. Methods: We conducted an analysis of randomized controlled trials in stroke rehabilitation over a 2-year period from 2019-2020. Results: There were three primary findings: (i) consistent with prior reports, most studies did not provide an explicit rationale for why the treatment would be expected to work, (ii) most therapeutic interventions mentioned multiple active ingredients and there was not a close correspondence between the active ingredients mentioned versus the active ingredients measured in the study, and (iii) multimodal approaches that involved more than one therapeutic approach tended to be combined in an ad-hoc fashion, indicating the lack of a targeted approach. Conclusion: These results highlight the need for strengthening cross-disciplinary connections between basic science and clinical studies, and the need for structured development and testing of therapeutic approaches to find more effective treatment interventions.

A hybrid cost-sensitive machine learning approach for the classification of intelligent disease diagnosis

Automatic risk classification of diseases is one of the most significant health problems in medical and healthcare domain. However, the related studies are relative scarce. In this paper, we design an intelligent diagnosis model based on optimal machine learning algorithms with rich clinical data. First, the disease risk classification problem based on machine learning is defined. Then, the K-means clustering algorithm is used to validate the class label of given data, thereby removing misclassified instances from the original dataset. Furthermore, naive Bayesian algorithm is applied to build the final classifier by using 10-fold cross-validation method. In addition, a novel class-specific attribute weighted approach is adopted to alleviate the conditional independence assumption of naive Bayes, which means we assign each disease attribute a specific weight for each class. Last but not least, a hybrid cost-sensitive disease risk classification model is formulated, and a practical example from the University of California Irvine (UCI) machine learning database is used to illustrate the potential of the proposed method. Experimental results demonstrate that the approach is competitive with the state-of-the-art classifiers.

Primary Care of Adult Patients After Stroke: A Scientific Statement From the American Heart Association/American Stroke Association

Primary care teams provide the majority of poststroke care. When optimally configured, these teams provide patient-centered care to prevent recurrent stroke, maximize function, prevent late complications, and optimize quality of life. Patient-centered primary care after stroke begins with establishing the foundation for poststroke management while engaging caregivers and family members in support of the patient. Screening for complications (eg, depression, cognitive impairment, and fall risk) and unmet needs is both a short-term and long-term component of poststroke care. Patients with ongoing functional impairments may benefit from referral to appropriate services. Ongoing care consists of managing risk factors such as high blood pressure, atrial fibrillation, diabetes, carotid stenosis, and dyslipidemia. Recommendations to reduce risk of recurrent stroke also include lifestyle modifications such as healthy diet and exercise. At the system level, primary care practices can use quality improvement strategies and available resources to enhance the delivery of evidence-based care and optimize outcomes.

Internet Access and Usage Among Stroke Survivors and Their Informal Caregivers: Cross-sectional Study

Background

Web-based interventions have shown promise for chronic disease management but have not been widely applied to populations with stroke. Existing barriers may inhibit the adoption of web-based interventions among stroke survivors and necessitate the involvement of informal caregivers. However, limited information is available on internet accessibility and usability among stroke survivors and their caregivers.

Objective

This study aims to investigate internet access and usage in a cohort of stroke survivors and their caregivers.

Methods

A cross-sectional survey was conducted with 375 participants (248 stroke survivors and 127 caregivers). Descriptive statistics were generated using cross-tabulation. Comparisons with categorical data were conducted using the chi-square test, whereas the Mann-Whitney U test was used for comparisons involving ordinal variables.

Results

Overall, 86.1% (323/375) of the participants reported having internet access. Caregivers were more likely than stroke survivors to access the internet (N=375, χ²₁=18.5, P<.001) and used text messaging (n=321, χ²₁=14.7, P<.001). Stroke survivors and caregivers with internet access were younger than stroke survivors and caregivers without internet access. The highest number of participants who reported internet access were non-Hispanic White. Smartphones were the most common devices used to access the internet. Email was the most common type of internet usage reported. Patients who survived for >12 months after a stroke reported higher internet access than those who survived <3 months (P<.001). The number of hours per week spent using the internet was higher for caregivers than for stroke survivors (P<.001).

Conclusions

Future feasibility and acceptability studies should consider the role of the informal caregiver, participant age, race and ethnicity, the use of smartphone apps, email and text correspondence, and the amount of time elapsed since the stroke event in the design and implementation of web-based interventions for populations with stroke.

Delivering motivational interviewing early post stroke: standardisation of the intervention

BACKGROUND

We applied Motivational Interviewing (MI) techniques, early after stroke, to facilitate psychological adjustment to life post-stroke. In our trial, MI-plus-usual-care increased the likelihood of normal mood at 3-months post-stroke, compared to usual-care alone. Whilst appropriate training, manuals, and supervision may increase adherence to core principles of this complex intervention, unintended variability in implementation inevitably remains. We aimed to explore the impact of variability on participant outcome.

METHODS

Using our trial data (411 participants), we explored variation in MI delivery, examining: therapist characteristics (stroke care expertise/knowledge, psychology training); MI content (fidelity to MI techniques assessed with Motivational Interviewing Treatment Integrity code, describing therapist behaviours as MI-consistent, MI-neutral or MI-inconsistent); and MI dose (number/duration of sessions).

RESULTS

The four MI therapists (two nurses/two psychologists) had varying expertise and MI delivery. Across therapists, mean average session duration ranged 29.5-47.8 min. The percentage of participants completing the per-protocol four sessions ranged 47%-74%. These variations were not related to participant outcome. There were uniformly high frequencies (>99%) of MI-consistent and MI-neutral interactions, and low frequencies (<1%) of MI-inconsistent interactions.

CONCLUSIONS

Variation in therapist characteristics and MI dose did not affect participant outcome. These may have been tolerated due to high fidelity to MI principles.IMPLICATIONS FOR REHABILITATIONMotivational Interviewing (MI) can help reduce depression in stroke survivors when delivered early after stroke.The effectiveness of our MI intervention depends on the delivery of high quality MI; in particular, interactions with low levels of MI-inconsistency, and high global MI ratings, ideally delivered over more than one session, each lasting at least 30 minutes.Provided high quality MI is being delivered, the intervention can still have a beneficial effect on participant outcome, even with flexibility and variation in therapist characteristics, and duration and number of sessions, which may be inevitable in a clinical context.

Impact of a theory-informed and user-centered stroke information campaign on the public's behaviors, attitudes, and knowledge when facing acute stroke: a controlled before-and-after study

Background

Public awareness of stroke symptoms is a key factor to ensure access to reperfusion strategies in due time. We designed and launched a regional theory-informed and user-centered information campaign and assessed its impact on emergency medical services (EMS) calls for stroke suspicion, time-to-call, and public attitudes and awareness concerning stroke.

Methods

A controlled before-and-after study was conducted during 3 sequential time-periods in 2 separate counties. Key messages of the campaign were underpinned by stroke representations and the theory of planned behavior, and focused on recognition of stroke warning signs and the need to call EMS urgently. The campaign included posters, leaflets, adverts and films displayed in bus and subway stations, internet, social networks, and local radio. Outcome measures on behavior, attitudes, and knowledge were assessed before the launch of the campaign, at 3 months, and 12 months.

Results

The number of EMS calls for stroke suspicion increased by 21% at 12 months in the intervention county and this change was significantly different to that observed in the control county (p = 0.02). No significant changes were observed regarding self-reported attitudes in case of stroke. An 8% significant increase in recognizing at least 2 stroke warning signs was observed in the intervention county (p = 0.04) at 3 months, while it did not change significantly in the control county (p = 0.6). However, there was no significant difference in warning sign recognition between both counties (p = 0.16).

Conclusion

The campaign significantly improved public’s behavior of calling EMS, although stroke knowledge was not improved as much as expected. Repeating these campaigns over time might further help improve timeliness and access to reperfusion strategies.

An Initial Investigation of the Responsiveness of Temporal Gait Asymmetry to Rhythmic Auditory Stimulation and the Relationship to Rhythm Ability Following Stroke

Temporal gait asymmetry (TGA) is a persistent post-stroke gait deficit. Compared to conventional gait training techniques, rhythmic auditory stimulation (RAS; i.e., walking to a metronome) has demonstrated positive effects on post-stroke TGA. Responsiveness of TGA to RAS may be related to several factors including motor impairment, time post-stroke, and individual rhythm abilities. The purpose of this study was to investigate the relationship between rhythm abilities and responsiveness of TGA when walking to RAS. Assessed using behavioral tests of beat perception and production, participants with post-stroke TGA (measured as single limb support time ratio) were categorized according to rhythm ability (as strong or weak beat perceivers/producers). We assessed change in TGA between walking without cues (baseline) and walking while synchronizing footsteps with metronome cues. Most individuals with stroke were able to maintain or improve TGA with a single session of RAS. Within-group analyses revealed a difference between strong and weak rhythm ability groups. Strong beat perceivers and producers showed significant reduction (improvement) in TGA with the metronome. Those with weak ability did not and exhibited high variability in the TGA response to metronome. Moreover, individuals who worsened in TGA when walking to metronome had poorer beat production scores than those who did not change in TGA. However, no interaction between TGA improvement when walking to metronome and rhythm perception or production ability was found. While responsiveness of TGA to RAS did not significantly differ based on strength of rhythm abilities, these preliminary findings highlight rhythm ability as a potential consideration when treating post-stroke individuals with rhythm-based treatments.

Two-level multi-methodological evaluation of a new complex primary support programme for stroke care-givers in Germany

Family care-givers are the backbone of the long-term support system for care receivers at home. Care for stroke survivors after rehabilitation primarily rests on the shoulders of family members, often of older age themselves. We report the outcomes of a new complex support programme, the Care-givers’ Guide, on both individual and system levels. Psycho-social support and personalised information were the main ingredients of this intervention. A two-level multi-methodological approach was needed, with two concurrent interconnected studies. Family care-givers reflected on outcomes at an individual level in a quant-QUAL study with a pre–post quantitative questionnaire and a post-intervention qualitative semi-structured interview. Practitioners participated in a QUAL-QUAL study ex post interview, reflecting on the outcomes on the care-givers and on their own stroke care system. Individual family care-givers showed an increase in health literacy and level of psycho-social health. Qualitative analysis revealed improvement in knowledge, capability to act and individual empowerment; and stabilisation of sense of certainty, life balance and emotional wellbeing. Practitioners observed an optimisation of the stroke support system by improving professionals’ daily routine, augmenting the institutional support offer, securing the quality of patient care and increasing inter-institutional co-operation attempts. Positive outcomes of the support programme were observed on both evaluation levels: family care-givers showed improved health literacy and psycho-social health, whereas the professionals noticed an optimisation of the support system.

Urinary incontinence in stroke survivors - Development of a programme theory

AIMS AND OBJECTIVES

To develop, in an inpatient rehabilitation setting, a programme theory that promotes continence in people who have suffered a stroke.

BACKGROUND

Urinary incontinence in stroke survivors impacts the quality of life, rehabilitation outcomes and ultimately incurred costs of the patient. Different approaches are available for developing and testing complex interventions.

DESIGN

Building a research-based programme theory.

METHODS

To elaborate the intervention, a guidance for developing a complex intervention for nursing was chosen and the sources that should be considered were defined. Subsequently, a research-based programme theory was generated that was represented via a theoretical approach logic model. This study was guided by the checklist for reporting theory of change in public health interventions.

RESULTS

The intervention consists of six parts with three outcome chains on interconnected levels, which are oriented towards patients and nurses. The important aspects of the programme theory are communication, individually tailored measures and the definition of interdisciplinary objectives.

CONCLUSION

Developing a programme theory and representing it via a logic model help clarify the initial intervention and ensure that implementation strategies are well thought out.

RELEVANCE TO CLINICAL PRACTICE

By employing detailed reflection and using previous research, it is expected that the intervention can be implemented successfully and its effectiveness can be investigated in more depth.

A feasibility, acceptability and fidelity study of a multifaceted behaviour change intervention targeting free-living physical activity and sedentary behaviour in community dwelling adult stroke survivors

Background

Despite the benefits of physical activity for walking ability, balance, and mood, less than 30% of stroke survivors engage in recommended levels of physical activity with high levels of sedentary behaviour observed. This study aims to assess the feasibility, acceptability and fidelity of a theory- and evidence-based multifaceted behaviour change intervention targeting free-living physical activity and sedentary behaviour after stroke.

Methods

This study will be set in community stroke services in the North East of England and will assess the feasibility of a behaviour change intervention targeting free-living physical activity and sedentary behaviour of stroke survivors and consultation behaviour of the healthcare professionals to support stroke survivors to make these lifestyle changes. Up to 35 stroke survivors currently receiving stroke rehabilitation within the study catchment area with capacity and no contraindications to increasing physical activity/reducing sedentary behaviour will be recruited. Stroke survivors will receive a supported self-management physical activity/sedentary behaviour programme incorporating provision of information, goal setting, action planning, barrier identification, coping planning, self-monitoring and feedback on physical activity and sedentary behaviour. The programme will be supported by up to 12 healthcare professionals (HCPs) recruited from the community stroke services taking part in the study. The HCPs will deliver at least two face-to-face sessions (baseline, review and subsequent reviews if necessary) and provide a range of personalised tools to support each individual stroke survivor (e.g. workbook, self-monitoring tools, information on local resources). The consultation behaviour of the HCPs will be targeted via a training programme incorporating face-to-face training, a training manual and individual feedback on intervention programme delivery from the study research team. The feasibility, acceptability and fidelity of the study protocol will be assessed.

Discussion

The most effective methods of supporting stroke survivors to alter physical activity and sedentary behaviour have yet to be established. This study will establish the feasibility of delivering a complex theory- and evidence-based intervention targeting the behaviour of both stroke survivors and HCPs and assess whether it is acceptable to the target populations. Findings will inform the iterative development of the intervention before a larger scale evaluation.

The protocol-guided rapid evaluation of veterans experiencing new transient neurological symptoms (PREVENT) quality improvement program: rationale and methods

BACKGROUND

Transient ischemic attack (TIA) patients are at high risk of recurrent vascular events; timely management can reduce that risk by 70%. The Protocol-guided Rapid Evaluation of Veterans Experiencing New Transient Neurological Symptoms (PREVENT) developed, implemented, and evaluated a TIA quality improvement (QI) intervention aligned with Learning Healthcare System principles.

METHODS

This stepped-wedge trial developed, implemented and evaluated a provider-facing, multi-component intervention to improve TIA care at six facilities. The unit of analysis was the medical center. The intervention was developed based on benchmarking data, staff interviews, literature, and electronic quality measures and included: performance data, clinical protocols, professional education, electronic health record tools, and QI support. The effectiveness outcome was the without-fail rate: the proportion of patients who receive all processes of care for which they are eligible among seven processes. The implementation outcomes were the number of implementation activities completed and final team organization level. The intervention effects on the without-fail rate were analyzed using generalized mixed-effects models with multilevel hierarchical random effects. Mixed methods were used to assess implementation, user satisfaction, and sustainability.

DISCUSSION

PREVENT advanced three aspects of a Learning Healthcare System. Learning from Data: teams examined and interacted with their performance data to explore hypotheses, plan QI activities, and evaluate change over time. Learning from Each Other: Teams participated in monthly virtual collaborative calls. Sharing Best Practices: Teams shared tools and best practices. The approach used to design and implement PREVENT may be generalizable to other clinical conditions where time-sensitive care spans clinical settings and medical disciplines.

Developing interventions to improve health: a systematic mapping review of international practice between 2015 and 2016

BACKGROUND

Researchers publish the processes they use to develop interventions to improve health. Reflecting on this endeavour may help future developers to improve their practice.

METHODS

Our aim was to collate, describe, and analyse the actions developers take when developing complex interventions to improve health. We carried out a systematic mapping review of empirical research studies that report the development of complex interventions to improve health. A search was undertaken of five databases over 2015-2016 using the term 'intervention dev*'. Eighty-seven journal articles reporting the process of intervention development were identified. A purposive subset of 30 articles, using a range of published approaches to developing interventions, was selected for in-depth analysis using principles of realist synthesis to identify the actions of intervention development and rationales underpinning those actions.

RESULTS

The 87 articles were from the USA (39/87), the UK (32/87), continental Europe (6/87), and the rest of the world (10/87). These mainly took a pragmatic self-selected approach (n = 43); a theory- and evidence-based approach, e.g. Intervention Mapping, Behaviour Change Wheel (n = 22); or a partnership approach, e.g. community-based participatory research, co-design (n = 10). Ten actions of intervention development were identified from the subset of 30 articles, including identifying a need for an intervention, selecting the intervention development approach to follow, considering the needs of the target population, reviewing published evidence, involving stakeholders, drawing or generating theory, and designing and refining the intervention. Rationales for these actions were that they would produce more engaging, acceptable, feasible, and effective interventions.

CONCLUSIONS

Developers take a variety of approaches to the international endeavour of complex intervention development. We have identified and described a set of actions taken within this endeavour regardless of whether developers follow a published approach or not. Future developers can use these actions and the rationales that underpin them to help them make decisions about the process of intervention development.

The development of implementation management instruments for a new complex stroke caregiver intervention based on systematic stakeholder and risk analyses

BACKGROUND

Stakeholders are important contributors in the implementation of a complex public health intervention. During the development phase of an implementation, alongside careful design of its components and investing in the exploration of the dynamic multi-stakeholder stroke rehabilitation setting, it is essential to assess possible implementation risks. Systematic stakeholder and risk analyses can guide the exploration process and enable teams involved in complex interventions to develop context-tailored implementation management instruments.

PURPOSE

To develop instruments that facilitate the implementation of the complex stroke caregiver intervention project in the real-life support system.

METHODS

Systematic stakeholder and risk analyses were conducted composing five activities. Project stakeholders were identified, classified and assessed using a top-down approach, while implementation risks were identified and assessed by applying a bottom-up approach. Data were collected through interviews and focus groups.

RESULTS

Based on the knowledge provided by the stakeholders, two context-tailored implementation management instruments were designed with a top-down approach: (1) a comprehensive 'stakeholder-risk atlas' providing individual stakeholder information, such as role, access, contribution, power and interest, expectations, perceived risks and specific engagement activities and (2) an overall 'project implementation strategy' concentrating on communication, transparency, network building and professionalism.

CONCLUSION

Complex interventions will benefit from early and comprehensive stakeholder and risk analyses. The early involvement of stakeholders, with their insightful knowledge, enables the research team to develop context-tailored implementation management instruments. Instruments will support the team during implementation and may impact positively on the outcome of the intervention. Knowledge can be obtained by combining top-down and bottom-up working approaches.

Taxonomy of approaches to developing interventions to improve health: a systematic methods overview

Background

Interventions need to be developed prior to the feasibility and piloting phase of a study. There are a variety of published approaches to developing interventions, programmes or innovations to improve health. Identifying different types of approach, and synthesising the range of actions taken within this endeavour, can inform future intervention development.

Methods

This study is a systematic methods overview of approaches to intervention development. Approaches were considered for inclusion if they described how to develop or adapt an intervention in a book, website or journal article published after 2007, or were cited in a primary research study reporting the development of a specific intervention published in 2015 or 2016. Approaches were read, a taxonomy of approaches was developed and the range of actions taken across different approaches were synthesised.

Results

Eight categories of approach to intervention development were identified. (1) Partnership, where people who will use the intervention participate equally with the research team in decision-making about the intervention throughout the development process. (2) Target population-centred, where the intervention is based on the views and actions of the people who will use it. (3) Evidence and theory-based, where the intervention is based on published research evidence and existing theories. (4) Implementation-based, where the intervention is developed with attention to ensuring it will be used in the real world. (5) Efficiency-based, where components of an intervention are tested using experimental designs to select components which will optimise efficiency. (6) Stepped or phased, where interventions are developed with an emphasis on following a systematic set of processes. (7) Intervention-specific, where an approach is constructed for a specific type of intervention. (8) Combination, where existing approaches to intervention development are formally combined. The actions from approaches in all eight categories were synthesised to identify 18 actions to consider when developing interventions.

Conclusions

This overview of approaches to intervention development can help researchers to understand the variety of existing approaches, and to understand the range of possible actions involved in intervention development, prior to assessing feasibility or piloting the intervention. Findings from this overview will contribute to future guidance on intervention development.

The development and feasibility of an online aphasia group intervention and networking program - TeleGAIN

PURPOSE

Aphasia group therapy offers many benefits, however people with aphasia report difficulty accessing groups and speech-language pathologists are faced with many challenges in providing aphasia group therapy. Telerehabilitation may offer an alternative service delivery option. An online aphasia group therapy program - Telerehabilitation Group Aphasia Intervention and Networking (TeleGAIN) - has been developed according to the guidelines of the Medical Research Council (MRC) framework for complex interventions. The purpose of this paper is to describe the development of TeleGAIN and the results of a pilot trial to determine feasibility and acceptability.

METHOD

The development of TeleGAIN was informed through literature reviews in relevant topic areas, consideration of expert opinion and application of the social cognitive theory. TeleGAIN was then modelled through a feasibility pilot trial with four people with aphasia.

RESULT

TeleGAIN appeared to be feasible and acceptable to participants and able to be implemented as planned. Participant satisfaction with treatment was high and results suggested some potential for improvements in language functioning and communication-related quality of life.

CONCLUSION

TeleGAIN appeared to be feasible and acceptable, however the study highlighted issues related to technology, clinical implementation and participant-specific factors that should be addressed prior to a larger trial.

The generation of consensus guidelines for carrying out process evaluations in rehabilitation research

BACKGROUND

Although in recent years there has been a strong increase in published research on theories (e.g. realist evaluation, normalization process theory) driving and guiding process evaluations of complex interventions, there is limited guidance to help rehabilitation researchers design and carry out process evaluations. This can lead to the risk of process evaluations being unsystematic. This paper reports on the development of new consensus guidelines that address the specific challenges of conducting process evaluations alongside clinical trials of rehabilitation interventions.

METHODS

A formal consensus process was carried out based on a modified nominal group technique, which comprised two phases. Phase I was informed by the findings of a systematic review, and included a nominal group meeting with an expert panel of participants to rate and discuss the proposed statements. Phase II was an in depth semi-structured telephone interviews with expert panel participants in order to further discuss the structure and contents of the revised guidelines. Frequency of rating responses to each statement was calculated and thematic analysis was carried out on all qualitative data.

RESULTS

The guidelines for carrying out process evaluations within complex intervention rehabilitation research were produced by combining findings from Phase I and Phase II. The consensus guidelines include recommendations that are grouped in seven sections. These sections are theoretical work, design and methods, context, recruitment and retention, intervention staff, delivery of the intervention and results. These sections represent different aspects or stages of the evaluation process.

CONCLUSION

The consensus guidelines here presented can play a role at assisting rehabilitation researchers at the time of designing and conducting process evaluations alongside trials of complex interventions. The guidelines break new ground in terms of concepts and theory and works towards a consensus in regards to how rehabilitation researchers should go about carrying out process evaluations and how this evaluation should be linked into the proposed trials. These guidelines may be used, adapted and tested by rehabilitation researchers depending on the research stage or study design (e.g. feasibility trial, pilot trial, etc.).

Improving the development, monitoring and reporting of stroke rehabilitation research: Consensus-based core recommendations from the Stroke Recovery and Rehabilitation Roundtable

Recent reviews have demonstrated that the quality of stroke rehabilitation research has continued to improve over the last four decades but despite this progress, there are still many barriers in moving the field forward. Rigorous development, monitoring and complete reporting of interventions in stroke trials are essential in providing rehabilitation evidence that is robust, meaningful and implementable. An international partnership of stroke rehabilitation experts committed to develop consensus-based core recommendations with a remit of addressing the issues identified as limiting stroke rehabilitation research in the areas of developing, monitoring and reporting stroke rehabilitation interventions. Work exploring each of the three areas took place via multiple teleconferences and a two-day meeting in Philadelphia in May 2016. A total of 15 recommendations were made. To validate the need for the recommendations, the group reviewed all stroke rehabilitation trials published in 2015 (n = 182 papers). Our review highlighted that the majority of publications did not clearly describe how interventions were developed or monitored during the trial. In particular, under-reporting of the theoretical rationale for the intervention and the components of the intervention call into question many interventions that have been evaluated for efficacy. More trials were found to have addressed the reporting of interventions recommendations than those related to development or monitoring. Nonetheless, the majority of reporting recommendations were still not adequately described. To progress the field of stroke rehabilitation research and to ensure stroke patients receive optimal evidence-based clinical care, we urge the research community to endorse and adopt our recommendations.

Promoting psychosocial well-being following stroke: study protocol for a randomized, controlled trial

Background

Stroke is a major public health threat globally. Psychosocial well-being may be affected following stroke. Depressive symptoms, anxiety, general psychological distress and social isolation are prevalent. Approximately one third report depressive symptoms and 20% report anxiety during the first months or years after the stroke. Psychosocial difficulties may impact significantly on long-term functioning and quality of life, reduce the effects of rehabilitation services and lead to higher mortality rates. The aim of the study is to evaluate the effect of a previously developed and feasibility tested dialogue-based psychosocial intervention aimed at promoting psychosocial well-being and coping following stroke among stroke survivors with and without aphasia.

Methods

The study will be conducted as a multicenter, randomized, single blind controlled trial with one intervention and one control arm. It will include a total of 330 stroke survivors randomly allocated into either an intervention group (dialogue-based intervention to promote psychosocial well-being) or a control group (usual care). Participants in the intervention group will receive eight individual sessions of supported dialogues in their homes during the first six months following an acute stroke. The primary outcome measure will be psychosocial well-being measured by the General Health Questionnaire (GHQ). Secondary outcome measures will be quality of life (SAQoL), sense of coherence (SOC), and depression (Yale). Process evaluation will be conducted in a longitudinal mixed methods study by individual qualitative interviews with 15–20 participants in the intervention and control groups, focus group interviews with the intervention personnel and data collectors, and a comprehensive analysis of implementation fidelity.

Discussion

The intervention described in this study protocol is based on thorough development and feasibility work, guided by the UK medical research council framework for developing and testing complex interventions. It combines classical effectiveness evaluation with a thorough process evaluation. The results from this study may inform the development of further trials aimed at promoting psychosocial well-being following stroke as well as inform the psychosocial follow up of stroke patients living at home.

Factors associated with changes over time in medication-taking behavior up to 12 months after initial mild cerebral infarction onset

PURPOSE

The aim of this study was to clarify the changes in medication-taking behavior and related factors over time in patients with initial mild cerebral infarction up to 12 months after onset.

METHODS

Thirty-one patients with initial mild cerebral infarction were surveyed a total of four times: on admission to hospital, 3 months after onset, 6 months after onset, and 12 months after onset. Patients were surveyed regarding medication compliance, awareness of taking medication, perceived behavioral control, lifestyle risk factors, and subjective norms.

RESULTS

Medication compliance improved over time from the time of admission, but no changes were seen in awareness of taking medication. A cluster analysis based on changes in medication compliance over time revealed a "Persistently high compliance group" and a "Persistently low compliance group" for medication compliance. The health locus of control in the "Persistently high compliance group" was perceived as the result of chance and fate.

CONCLUSIONS

Assessing the current state of medication compliance and the health locus of control during hospitalization permitted an understanding of patient characteristics, and indicated a need for recurrence prevention education and medication guidance tailored to each patient's cognitive and behavioral characteristics.

A pilot study to assess the practicality, acceptability and feasibility of a randomised controlled trial to evaluate the impact of a pharmacist complex intervention on patients with stroke in their own homes

OBJECTIVE

To test the practicality, acceptability and feasibility of recruitment, data collection, blood pressure (BP) monitoring and pharmaceutical care processes, in order to inform the design of a definitive randomised controlled trial of a pharmacist complex intervention on patients with stroke in their own homes.

METHODS

Patients with new stroke from acute, rehabilitation wards and a neurovascular clinic (NVC) were randomised to usual care or to an intervention group who received a home visit at 1, 3 and 6 months from a clinical pharmacist. Pharmaceutical care comprised medication review, medicines and lifestyle advice, pharmaceutical care issue (PCI) resolution and supply of individualised patient information. A pharmaceutical care plan was sent to the General Practitioner and Community Pharmacy. BP and lipids were measured for both groups at baseline and at 6 months. Questionnaires covering satisfaction, quality of life and medicine adherence were administered at 6 months.

RESULTS

Of the 430 potentially eligible patients, 30 inpatients and 10 NVC outpatients were recruited. Only 33/364 NVC outpatients (9.1%) had new stroke. 35 patients completed the study (intervention=18, usual care=17). Questionnaire completion rates were 91.4% and 84.4%, respectively. BP and lipid measurement processes were unreliable. From 104 identified PCIs, 19/23 recommendations (83%) made to general practitioners were accepted.

CONCLUSION

Modifications to recruitment is required to include patients with transient ischaemic attack. Questionnaire response rates met criteria but completion rates did not, which merits further analysis. Lipid measurements are not necessary as an outcome measure. A reliable BP-monitoring process is required.

Development of a Chronic Disease Management Program for Stroke Survivors Using Intervention Mapping: The Stroke Coach

OBJECTIVE

To describe the systematic development of the Stroke Coach, a theory- and evidence-based intervention to improve control of lifestyle behavior risk factors in patients with stroke.

DESIGN

Intervention development.

SETTING

Community.

PARTICIPANTS

Individuals who have had a stroke.

INTERVENTIONS

We used intervention mapping to guide the development of the Stroke Coach. Intervention mapping is a systematic process used for intervention development and composed of steps that progress from the integration of theory and evidence to the organization of realistic strategies to facilitate the development of a practical intervention supported by empirical evidence. Social cognitive theory was the underlying premise for behavior change, whereas control theory methods were directed toward sustaining the changes to ensure long-term health benefits. Practical evidence-based strategies were linked to behavioral determinants to improve stroke risk factor control.

MAIN OUTCOME MEASURES

Not applicable.

RESULTS

The Stroke Coach is a patient-centered, community-based, telehealth intervention to promote healthy lifestyles after stroke. Over 6 months, participants receive seven 30- to 60-minute telephone sessions with a lifestyle coach who provides education, facilitates motivation for lifestyle modification, and empowers participants to self-management their stroke risk factors. Participants also receive a self-management manual and a self-monitoring kit.

CONCLUSIONS

Through the use of intervention mapping, we developed a theoretically sound and evidence-grounded intervention to improve risk factor control in patients with stroke. If empirical evaluation of the Stroke Coach produces positive results, the next step will be to develop an implementation intervention to ensure successful uptake and delivery of the program in community and outpatient settings.

Interventions for the uptake of evidence‐based recommendations in acute stroke settings

This is a protocol for a Cochrane Review (Intervention). The objectives are as follows:

To assess the effects of implementation interventions for promoting the uptake of evidence‐based recommendations in acute stroke unit environments. Secondary objectives are to describe any factors that may modify the effect of implementation interventions; determine factors that may influence the uptake of recommendations in acute stroke units; and determine if single or multifaceted intervention strategies (two or more interventions) are more effective in improving uptake of evidence, patient outcomes, system outcomes or professionals' knowledge, attitudes or intentions in this setting.

Process evaluations in neurological rehabilitation: a mixed-evidence systematic review and recommendations for future research

OBJECTIVE

To systematically review how process evaluations are currently designed, what methodologies are used and how are they developed alongside or within neurological rehabilitation trials.

METHODS

This mixed-methods systematic review had two evidence streams: stream I, studies reporting process evaluations alongside neurorehabilitation trials research and stream II, methodological guidance on process evaluation design and methodology. A search strategy was designed for each evidence stream. Data regarding process evaluation core concepts and design issues were extracted using a bespoke template. Evidence from both streams was analysed separately and then synthesised in a final overarching synthesis proposing a number of recommendations for future research.

RESULTS

A total of 124 process evaluation studies, reporting on 106 interventions, were included in stream I evidence. 30 studies were included as stream II evidence. Synthesis 1 produced 9 themes, and synthesis 2 identified a total of 8 recommendations for process evaluation research. The overall synthesis resulted in 57 'synthesis recommendations' about process evaluation methodology grouped into 9 research areas, including the use of theory, the investigation of context, intervention staff characteristics and the delivery of the trial intervention.

CONCLUSIONS

There remains no consensus regarding process evaluation terminology within the neurological rehabilitation field. There is a need for process evaluations to address the nature and influence of context over time. Process evaluations should clearly describe what intervention staff bring to a trial, including skills and experience prior to joining the research. Process evaluations should monitor intervention staff's learning effects and the possible impact that these may have on trial outcomes.

Primary care interventions and current service innovations in modifying long-term outcomes after stroke: a protocol for a scoping review

INTRODUCTION

Interventions delivered by primary and/or community care have the potential to reach the majority of stroke survivors and carers and offer ongoing support. However, an integrative account emerging from the reviews of interventions addressing specific long-term outcomes after stroke is lacking. The aims of the proposed scoping review are to provide an overview of: (1) primary care and community healthcare interventions by generalist healthcare professionals to stroke survivors and/or their informal carers to address long-term outcomes after stroke, (2) the scope and characteristics of interventions which were successful in addressing long-term outcomes, and (3) developments in current clinical practice.

METHODS AND ANALYSIS

Studies that focused on adult community dwelling stroke survivors and informal carers were included. Academic electronic databases will be searched to identify reviews of randomised controlled trials (RCTs) and controlled trials, trials from the past 5 years; reviews of observational studies. Practice exemplars from grey literature will be identified through advanced Google search. Reports, guidelines and other documents of major health organisations, clinical professional bodies, and stroke charities in the UK and internationally will be included. Two reviewers will independently screen titles, abstracts and full texts for inclusion of published literature. One reviewer will screen search results from the grey literature and identify relevant documents for inclusion. Data synthesis will include analysis of the number, type of studies, year and country of publication, a summary of intervention components/service or practice, outcomes addressed, main results (an indicator of effectiveness) and a description of included interventions.

ETHICS AND DISSEMINATION

The review will help identify components of care and care pathways for primary care services for stroke. By comparing the results with stroke survivors' and carers' needs identified in the literature, the review will highlight potential gaps in research and practice relevant to long-term care after stroke.

Why Patients Delay Their First Contact with Health Services After Stroke? A Qualitative Focus Group-Based Study

Background

Despite national and local French information campaigns, when acute stroke occurs, waiting times before calling mobile emergency medical services (EMS) to receive appropriate treatment (i.e. thrombolysis) and decrease the risk of physical disability, remain long. We aimed to identify the representations of stroke in the general population and to determine barriers to and facilitators for rapidly contacting EMS.

Method

We conducted a qualitative study among the general population with 10 focus groups, 5 comprising employed people (N = 29) and 5 comprising retirees (N = 32). The themes discussed were general knowledge about stroke and its risk factors, symptoms, appropriate management and the awareness that stroke is an emergency issue.

Results

In addition to a lack of knowledge about stroke, other barriers to rapidly contacting the EMS were difficulties in recognizing symptoms and understanding that these symptoms constitute an emergency. Furthermore, when faced with stroke, a feeling of inevitability and fatalism about the consequences of a stroke was highlighted. Participants were unaware of the existence of an effective treatment and they mistrusted medical competences. Finally, we found a strong presence and participant appreciation of common knowledge, resulting in the sharing of experiences of stroke. This could partly compensate for the lack of specific knowledge about symptom recognition and appropriate action.

Conclusion

Information campaigns should not only inform the public about stroke symptoms in order to ensure people act appropriately, but should also focus on increasing public awareness about the fact that an effective treatment exists.

Effects of a 4-week transitional care programme for discharged stroke survivors in Hong Kong: a randomised controlled trial

Stroke rehabilitation involves care issues concerning the physical, psychosocial and spiritual aspects. Hospital-based rehabilitation has its limitations because many of the care issues only emerge when patients return home. Transitional care models supporting patients after discharge from the hospital have proved to be effective among chronically ill patients, but limited studies were conducted among stroke survivors. This study was a randomised controlled trial conducted to test the effectiveness of a transitional care programme (TCP) which was a nurse-led 4-week programme designed based on the assessment-intervention-evaluation Omaha System framework. Between August 2010 and October 2011, 108 stroke patients who were discharged home, able to communicate, and had slight to moderate neurological deficits and disability were randomised into control (n = 54) and intervention groups (n = 54). Data on the patient-related and clinical outcomes were collected at baseline, 4 weeks when the TCP was completed and 8 weeks after discharge from hospital. Repeated measures analysis of variance with intention-to-treat strategy was used to examine the outcomes. There were significant between-group differences in quality of life, the primary outcome measure of this study, in both physical (F(1, 104) = 10.15, P = 0.002) and mental (F(1, 104) = 8.41, P = 0.005) domains, but only the physical domain achieved a significant time × intervention interaction effect (F(1, 103) = 7.73, P = 0.006). The intervention group had better spiritual-religion-personal measures, higher satisfaction, higher Modified Barthel Index scores and lower depression scores when compared with the control group. They also had lower hospital readmission and use of emergency room rates, but only the use of emergency room had significant difference when compared to control. This study is original in testing a transitional model among stroke patients discharged from hospital. The TCP shares common features that have been proved to be effective when applied to chronically ill patients, and the duration of 4 weeks seems to be adequate to bring about immediate effects.

Criteria for Reporting the Development and Evaluation of Complex Interventions in healthcare: revised guideline (CReDECI 2)

Background

Many healthcare interventions are of complex nature, consisting of several interacting components. Complex interventions are often described inadequately. A reporting guideline for complex interventions was published in 2012 (Criteria for Reporting the Development and Evaluation of Complex Interventions in healthcare, CReDECI) and was recently checked for its practicability. The reporting guideline was developed following the recommendations of the EQUATOR network but excluding a formal consensus process. Therefore, a consensus process was initiated, to revise the reporting guideline.

Methods

We used a three-phase consensus process consisting of (1) a web-based feedback survey on the published reporting guideline, (2) a face-to-face consensus conference, and (3) a final online review and feedback round to create the revised CReDECI. The consensus process was organized and conducted via the REFLECTION network.

Results

A total of 45 attendees from 16 European countries took part in the face-to-face consensus conference. The revised reporting guideline (CReDECI 2) comprises 13 items on three stages: development, feasibility and piloting, and evaluation of a complex intervention. Each item is illustrated by an explanation and an example. In contrast with most of the available reporting guidelines, CReDECI 2 does not focus on a specific study design, to reflect the use of different qualitative and quantitative designs and methods in the development and evaluation of complex interventions.

Conclusions

CReDECI 2 is a formally consented reporting guideline aiming to improve the reporting quality of the development and evaluation stages of complex interventions in healthcare. Since the guideline does not focus on a specific study design, design-specific reporting guidelines may additionally be used.

ICARUSS, the Integrated Care for the Reduction of Secondary Stroke trial: rationale and design of a randomized controlled trial of a multimodal intervention to prevent recurrent stroke in patients with a recent cerebrovascular event, ACTRN = 12611000264987

BACKGROUND

The majority of strokes, both ischaemic and haemorrhagic, are attributable to a relatively small number of risk factors which are readily manageable in primary care setting. Implementation of best-practice recommendations for risk factor management is calculated to reduce stroke recurrence by around 80%. However, risk factor management in stroke survivors has generally been poor at primary care level. A model of care that supports long-term effective risk factor management is needed.

AIM

To determine whether the model of Integrated Care for the Reduction of Recurrent Stroke (ICARUSS) will, through promotion of implementation of best-practice recommendations for risk factor management reduce the combined incidence of stroke, myocardial infarction and vascular death in patients with recent stroke or transient ischaemic attack (TIA) of the brain or eye.

DESIGN

A prospective, Australian, multicentre, randomized controlled trial.

SETTING

Academic stroke units in Melbourne, Perth and the John Hunter Hospital, New South Wales.

SUBJECTS

1000 stroke survivors recruited as from March 2007 with a recent (<3 months) stroke (ischaemic or haemorrhagic) or a TIA (brain or eye).

RANDOMIZATION

Randomization and data collection are performed by means of a central computer generated telephone system (IVRS).

INTERVENTION

Exposure to the ICARUSS model of integrated care or usual care.

PRIMARY OUTCOME

The composite of stroke, MI or death from any vascular cause, whichever occurs first.

SECONDARY OUTCOMES

Risk factor management in the community, depression, quality of life, disability and dementia.

STATISTICAL POWER

With 1000 patients followed up for a median of one-year, with a recurrence rate of 7-10% per year in patients exposed to usual care, the study will have at least 80% power to detect a significant reduction in primary end-points

CONCLUSION

The ICARUSS study aims to recruit and follow up patients between 2007 and 2013 and demonstrate the effectiveness of exposure to the ICARUSS model in stroke survivors to reduce recurrent stroke or vascular events and promote the implementation of best practice risk factor management at primary care level.

Multimodal secondary prevention behavioral interventions for TIA and stroke: a systematic review and meta-analysis

Background

Guidelines recommend implementation of multimodal interventions to help prevent recurrent TIA/stroke. We undertook a systematic review to assess the effectiveness of behavioral secondary prevention interventions.

Strategy

Searches were conducted in 14 databases, including MEDLINE (1980-January 2014). We included randomized controlled trials (RCTs) testing multimodal interventions against usual care/modified usual care. All review processes were conducted in accordance with Cochrane guidelines.

Results

Twenty-three papers reporting 20 RCTs (6,373 participants) of a range of multimodal behavioral interventions were included. Methodological quality was generally low. Meta-analyses were possible for physiological, lifestyle, psychosocial and mortality/recurrence outcomes. Note: all reported confidence intervals are 95%. Systolic blood pressure was reduced by 4.21 mmHg (mean) (−6.24 to −2.18, P = 0.01 I² = 58%, 1,407 participants); diastolic blood pressure by 2.03 mmHg (mean) (−3.19 to −0.87, P = 0.004, I² = 52%, 1,407 participants). No significant changes were found for HDL, LDL, total cholesterol, fasting blood glucose, high sensitivity-CR, BMI, weight or waist:hip ratio, although there was a significant reduction in waist circumference (−6.69 cm, −11.44 to −1.93, P = 0.006, I² = 0%, 96 participants). There was no significant difference in smoking continuance, or improved fruit and vegetable consumption. There was a significant difference in compliance with antithrombotic medication (OR 1.45, 1.21 to 1.75, P<0.0001, I² = 0%, 2,792 participants) and with statins (OR 2.53, 2.15 to 2.97, P< 0.00001, I² = 0%, 2,636 participants); however, there was no significant difference in compliance with antihypertensives. There was a significant reduction in anxiety (−1.20, −1.77 to −0.63, P<0.0001, I² = 85%, 143 participants). Although there was no significant difference in odds of death or recurrent TIA/stroke, there was a significant reduction in the odds of cardiac events (OR 0.38, 0.16 to 0.88, P = 0.02, I² = 0%, 4,053 participants).

Conclusions

There are benefits to be derived from multimodal secondary prevention interventions. However, the findings are complex and should be interpreted with caution. Further, high quality trials providing comprehensive detail of interventions and outcomes, are required.

Tackling the growing diabetes burden in Sub-Saharan Africa: a framework for enhancing outcomes in stroke patients

According to the World Health Organization (WHO), more than 80% of worldwide diabetes (DM)-related deaths presently occur in low- and middle-income countries (LMIC), and left unchecked these DM-related deaths will likely double over the next 20 years. Cardiovascular disease (CVD) is the most prevalent and detrimental complication of DM: doubling the risk of CVD events (including stroke) and accounting for up to 80% of DM-related deaths. Given the aforementioned, interventions targeted at reducing CVD risk among people with DM are integral to limiting DM-related morbidity and mortality in LMIC, a majority of which are located in Sub-Saharan Africa (SSA). However, SSA is contextually unique: socioeconomic obstacles, cultural barriers, under-diagnosis, uncoordinated care, and shortage of physicians currently limit the capacity of SSA countries to implement CVD prevention among people with DM in a timely and sustainable manner. This article proposes a theory-based framework for conceptualizing integrated protocol-driven risk factor patient self-management interventions that could be adopted or adapted in future studies among hospitalized stroke patients with DM encountered in SSA. These interventions include systematic health education at hospital discharge, use of post-discharge trained community lay navigators, implementation of nurse-led group clinics and administration of health technology (personalized phone text messaging and home tele-monitoring), all aimed at increasing patient self-efficacy and intrinsic motivation for sustained adherence to therapies proven to reduce CVD event risk.

Phone-based intervention under nurse guidance after stroke: concept for lowering blood pressure after stroke in Sub-Saharan Africa

Over the last 4 decades, rates of stroke occurrence in low- and middle-income countries (LMIC) have roughly doubled, whereas they have substantively decreased in high-income countries. Most of these LMIC are in Sub-Saharan Africa (SSA) where the burden of stroke will probably continue to rise over the next few decades because of an ongoing epidemiologic transition. Moreover, SSA is circumstantially distinct: socioeconomic obstacles, cultural barriers, underdiagnosis, uncoordinated care, and shortage of physicians impede the ability of SSA countries to implement cardiovascular disease prevention among people with diabetes mellitus in a timely and sustainable manner. Reducing the burden of stroke in SSA may necessitate an initial emphasis on high-risk individuals motivated to improve their health, multidisciplinary care coordination initiatives with clinical decision support, evidence-based interventions tailored for cultural relevance, task shifting from physicians to nurses and other health providers, use of novel patient-accessible tools, and a multilevel approach that incorporates individual- and system-level components. This article proposes a theory-based integrated blood pressure (BP) self-management intervention called Phone-based Intervention under Nurse Guidance after Stroke (PINGS) that could be tested among hospitalized stroke patients with poorly controlled hypertension encountered in SSA. PINGS would comprise the implementation of nurse-run BP control clinics and administration of health technology (personalized phone text messaging and home telemonitoring), aimed at boosting patient self-efficacy and intrinsic motivation for sustained adherence to antihypertensive medications.

Barriers and facilitators for medication adherence in stroke patients: a qualitative study conducted in French neurological rehabilitation units

OBJECTIVE

To describe the perceptions of French patients, caregivers and healthcare professionals on stroke and secondary preventive medications.

METHOD

A qualitative study was conducted, based on four predetermined topics: stroke, secondary prevention medications, patient's experience, relationship between patient/caregiver and healthcare team.

RESULTS

Twenty-six interviews were conducted. Difficulties in taking medications, lack of knowledge on stroke and medication benefits, fear of over medication were identified as barriers for adherence in patients. Doubts about generic drugs were expressed by caregivers. Healthcare professionals reported lack of knowledge and absence of clinical symptoms as barriers. On the other hand, support from caregivers and healthcare professional support is essential for compliance in all participants. Patients and caregivers expressed that fear of recurrence was a facilitator for treatment compliance.

CONCLUSION

This study highlights the barriers and facilitators for stroke treatment adherence and underlines the similarities and differences between the perceptions of patients, caregivers and healthcare professionals. These results must be integrated into the future French educational programs to improve medication adherence.

Risk awareness in secondary stroke prevention: a review of the literature

Despite improvements in the diagnosis and treatment of cardiovascular disease through medical advances, it remains the largest single cause of disability and the second leading cause of death on a global scale. Despite this, patient awareness of cardiovascular risk is low and adherence to secondary prevention measures is inadequate. This combined with an ageing population could have serious consequences for both personal and health care costs. Risk management has been used to design strategies to prevent both primary and secondary stroke. These strategies have largely relied upon health professionals providing information, support and monitoring of patients conditions and control of individual risk factors. However, these strategies have not always been successful in the long-term management and prevention of secondary cardiovascular disease. This review explores the literature surrounding risk awareness as a tool to improve patient adherence to medications and lifestyle behaviours to reduce risk of secondary stroke.

Promoting psychosocial wellbeing following stroke using narratives and guided self-determination: a feasibility study

BACKGROUND

Extensive studies have documented the complex and comprehensive psychosocial consequences of stroke. Psychosocial difficulties significantly affect long-term functioning and quality of life. Many studies have explored psychosocial interventions to prevent or treat psychosocial problems, but most have found modest effects. This study evaluated, from the perspective of adult stroke survivors, (1) the content, structure and process and (2) experienced usefulness of a dialogue-based psychosocial nursing intervention in primary care aimed at promoting psychosocial health and wellbeing.

METHODS

This was part of a feasibility study guided by the UK MRC complex interventions framework. It consisted of dialogue-based encounters with trained health professionals during approximately the first year poststroke. It was tested in two formats; individual or group encounters. Inclusion criteria were: Acute stroke, above 18 y.o., sufficient physical and cognitive functioning to participate. Data were collected immediately before, during and 14 days after the completion of the intervention. Pre- and post-data included medical and demographic data, quality of life, emotional wellbeing, life satisfaction, anxiety and depression. Qualitative interviews focusing on participant experiences were conducted two weeks following the intervention. Log notes taken by the health professionals conducting the intervention and work sheets filled in by participants also comprised data. Data analysis was case-oriented. The structured instruments were analysed regarding completeness of data and indication of changes in outcome variables. The qualitative interviews, log notes and work sheets were analysed using thematic content analysis.

RESULTS

Twenty-five stroke survivors (17 men, 8 women), median age 64 (range 33-89), participated. Physical limitations varied from mild to severe. Seven participants had moderate to severe expressive aphasia. The participants found the content and process of the intervention relevant. Both the individual and group formats were found useful. Patients with aphasia reported that there were too few encounters (eight encounters were originally planned). The participants underscored the benefits of being supported through a difficult time, having a chance to tell and (re)create their story and being supported in their attempts to cope with the situation.

CONCLUSIONS

This study provides initial support for the usefulness of the psychosocial intervention and highlights areas requiring further consideration and development.

Intracerebral implantation of autologous peripheral blood stem cells in stroke patients: a randomized phase II study

In our previous study, intracerebral implantation of peripheral blood stem cells (PBSCs) improved functional outcome in rats with chronic cerebral infarction. Based on this finding, a randomized, single blind controlled study was conducted in 30 patients [PBSC group (n = 15) and control group (n = 15)] with middle cerebral artery infarction confirmed on a T2-weighted MRI 6 months to 5 years after a stroke. Only subjects with neurological deficits of intermediate severity based on the National Institute of Health Stroke Scale (NIHSS; range: 9-20) that had been stable for at least 3 months were enrolled. Those in the PBSC group received subcutaneous G-CSF injections (15 µg/kg/day) for 5 consecutive days, and then stereotaxic implantation of 3-8 × 10(6) CD34(+) immunosorted PBSCs. All 30 patients completed the 12-month follow-up. No serious adverse events were noted during study period. Improvements in stroke scales (NIHSS, ESS, and EMS) and functional outcomes (mRS) from baseline to the end of the 12-month follow-up period were significantly greater in the PBSC than the control group. The fiber numbers asymmetry (FNA) scores based on diffusion tensor image (DTI) tractography were reduced in every PBSC-treated subject, but not in the control group. Reduction in the FNA scores correlated well with the improvement in NIHSS. Furthermore, a positive motor-evoked potential (MEP) response by transcranial magnetic stimulation (TMS) appeared in 9 of the 15 subjects in the PBSC group. This phase II study demonstrated that implantation of autologous CD34(+) PBSC was safe, feasible, and effective in improving functional outcome.

Quality of reporting of complex healthcare interventions and applicability of the CReDECI list - a survey of publications indexed in PubMed

Background

The development and evaluation of complex interventions in healthcare has obtained increased awareness. The Medical Research Council’s (MRC) framework for the development and evaluation of complex interventions and its update offers guidance for researchers covering the phases development, feasibility/piloting, and evaluation. Comprehensive reporting of complex interventions enhances transparency and is essential for researchers and policy-makers. Recently, a set of 16 criteria for reporting complex interventions in healthcare (CReDECI) was published. The aim of this study is to evaluate the reporting quality in publications of complex interventions adhering to either the first or the updated MRC framework, and to evaluate the applicability of CReDECI.

Methods

A systematic PubMed search was conducted. Two reviewers independently checked titles and abstracts for inclusion. Trials on complex interventions adhering to the MRC framework and including an evaluation study in English and German were included. For all included trials and for all publications which reported on phases prior to the evaluation study, related publications were identified via forward citation tracking. The quality of reporting was assessed independently by two reviewers using CReDECI. Inter-rater agreement and time needed to complete the assessment were determined.

Results

Twenty-six publications on eight trials were included. The number of publications per trial ranged from 1 to 6 (mean 3.25). The trials demonstrate a good reporting quality for the criteria referring to the development and feasibility/piloting. For the criteria addressing the introduction of the intervention and the evaluation, quality of reporting varied widely. Two trials fulfilled 7 and 8 items respectively, five trials fulfilled one to five items and one trial offered no information on any item. The mean number of items with differing ratings per trial was two. The time needed to rate a trial ranged from 30 to 90 minutes, depending on the number of publications.

Conclusions

Adherence to the MRC framework seems to have a positive impact on the reporting quality on the development and piloting of complex interventions. Reporting on the evaluation could be improved. CReDECI is a practical instrument to check the reporting quality of complex interventions and could be used alongside design-specific reporting guidelines.

Passed without a stroke: a UK mixed method study exploring student nurses' knowledge of stroke

AIMS AND OBJECTIVES

To evaluate third year student nurses' knowledge and experiences of stroke education. To identify how student nurses can develop their understanding of stroke and its application to clinical nursing practice.

BACKGROUND

Stroke is an international health issue and a major cause of morbidity and mortality in many countries throughout the world. Nurses have a significant role to play in reducing death and disability in people who have suffered a stroke and it has been suggested that some nurses may not be educationally prepared to meet the challenges of this complex condition.

DESIGN

This evaluative study was based on a mixed method evaluative design. These quantitative and qualitative approaches involved the implementation of focus groups and questionnaires.

METHOD

The following outcomes were measured during students' final year of their nursing studies: students' profiles and an assessment of students' knowledge of stroke.

RESULTS

There was a mixed picture of student nurses' knowledge of stroke; a lack of awareness of some fundamental aspects of stroke including common symptoms, complications, risk factors and the long term treatment. Reassuringly, students expressed decisively the importance for nurses to be equipped with a sound foundation of stroke knowledge for clinical practice.

CONCLUSIONS

All nursing students should have experience of being in contact with people who have had a stroke - and at present this does not always happen. A national intervention study is now suggested with a view to providing stroke education which is proportionate to its significance as a major health issue.

RELEVANCE TO CLINICAL PRACTICE

Nurses draw upon their fundamental clinical skills to care and treat patients who have survived a stroke. Additionally, stroke survivors also require enhanced knowledge and this is recognised in the growth of specialist stroke nurses. Improving stroke mortality and morbidity is the responsibility of all of us involved in nurse education - introducing creative evaluative interventions could hold the most promising way forward.

The reporting quality assessment of complex interventions' articles in traditional chinese medicine

Objective. To realize the current situation and problems of complex interventions' clinical trials. Methods. Searching at Chinese Journal Integrated Traditional and Western Medicine and Journal of Traditional Chinese Medicine from 2007 to 2012 by hand, we identified complex interventions' articles, and then we used the proposed criteria of complex interventions and CONSORT FOR TCM to evaluate. Results. All data is presented as counts with percentages and details in tables. Conclusion. Our evaluation presented that complex interventions have many defects: the selection of the intervention's components lacks rationale, complex interventions were short of fundamental researches, components' interactions were ambiguous, and the advantages of complex interventions were not mentioned. Furthermore, explanation of sample size, blind, quality control, ethical approval, and inform consent were neglected in different degrees.

Randomized controlled pilot study of a SystemCHANGE™ weight management intervention in stroke survivors: rationale and protocol

Background

Over 65% of stroke survivors are either overweight or obese and have multiple cardiovascular risk factors. However, few studies have examined the effects of comprehensive lifestyle behavior interventions to promote weight loss and control cardiovascular risk factors in stroke survivors. Thus, the purpose of this study is to examine a novel behavior change approach - SystemCHANGE™ - to promote weight loss and improve health and function in stroke survivors. SystemCHANGE™ focuses on redesigning the social environment to achieve a specific goal.

Methods

We will conduct a randomized controlled pilot study to examine the efficacy, feasibility, and safety of the SystemCHANGE™ weight management program in overweight and obese stroke survivors. The central hypothesis of the study is that the SystemCHANGE™ intervention will help overweight and obese stroke survivors lose 5% of their body weight, thereby improving health and function. Thirty-five stroke survivors will be randomized into either the 6-month SystemCHANGE™ intervention or a contact-control intervention. Outcome measures will be assessed at baseline and again at 3 and 6 months after the interventions. Body composition will be assessed using a Bod Pod. Patient-reported outcomes will be the Stroke Impact Scale and Reintegration to Normal Living Index. Objective outcomes will include the 6-Minute Walking Test and Rivermead Motor Assessment.

Discussion

This study will be the first randomized controlled trial to evaluate the efficacy and safety of a weight management intervention in stroke survivors using the SystemCHANGE™ approach. Furthermore, it will be the first empirically-examined comprehensive lifestyle intervention designed to target physical activity, nutrition, and sleep to promote weight loss in stroke survivors.

Reducing depression in stroke survivors and their informal caregivers: a randomized clinical trial of a Web-based intervention

PURPOSE/OBJECTIVES

To develop and test the efficacy of a Web-based intervention for alleviating depression in male stroke survivors (SSs) and their spousal caregivers (CGs) that blends both peer and professional support.

DESIGN AND METHODS

The research consisted of an intervention protocol evaluated by a focus group of rehabilitation professionals, a "think aloud" session conducted with female stroke CGs, and a usability test of the intervention's online features with 7 female stroke CGs. Efficacy of the final protocol was tested in a 2-group randomized clinical trial with a sample of 32 CG-SS dyads. The CGs in the intervention condition received an online group intervention. Intervention components were based on the Stress Process Model. Those CGs in a control condition received minimal support with individualized access to relevant online information. Measures of depression, as well as the secondary outcomes of mastery, self-esteem, and social support, were obtained from SSs and CGs at pretest, posttest, and 1-month later.

RESULTS

At posttest and 1 month later, CGs in the intervention condition reported significantly lower depression than CGs in the control condition with baseline depression controlled. There was no significant effect on depression among SSs. Although no significant treatment effects for either SSs or CGs were found on the secondary outcomes, posttreatment changes on some constructs were significantly correlated with change in depression.

CONCLUSIONS/IMPLICATIONS

CGs benefit from Web-based programs that help them better understand both their emotional needs and those of the SS.
