Top 10 research priorities relating to stroke nursing: a rigorous approach to establish a national nurse-led research agenda

Effects of non-pharmacological interventions on fatigue in people with stroke: a systematic review and meta-analysis

BACKGROUND

Fatigue, a common problem following a stroke, can have negative effects on a person's daily life. There are no good interventions thus far for alleviating fatigue among those affected.

OBJECTIVE

This review aimed to evaluate the effects of non-pharmacological interventions on fatigue among people with stroke.

METHODS

A search was conducted for articles in seven databases, clinical trial registry, and backward and forward citations of included publications. Randomized controlled trials, including feasibility and pilot trials, of non-pharmacological interventions for managing fatigue or promoting sleep or both in people with stroke were included. The standardized mean difference in scores for fatigue was analyzed using random effects models.

RESULTS

Ten studies, with 806 participants, were analyzed. The identified interventions included physical interventions, cognitive interventions, a combination of physical and cognitive interventions, oxygen therapy, and complementary interventions. Non-pharmacological interventions had no significant immediate, short-term and medium-term effects on fatigue. The adverse effects of falls and arrhythmia were each found in one participant in circuit training. The risk of bias was high in all studies. The certainty of the evidence ranged from very low to low.

CONCLUSIONS

The evidence in support of any non-pharmacological interventions for alleviating fatigue is still inconclusive in people with stroke. In view of the inadequacies of existing interventions and study designs, addressing the multidimensional characteristics of fatigue may be a possible direction in developing interventions. A robust study design with a larger sample size of people with stroke experiencing fatigue is required to evaluate the effects of interventions.

Post-stroke fatigue, hope and discharge readiness: A cross-sectional survey

AIMS AND OBJECTIVES

To explore the relationships among post-stroke fatigue, hope and discharge readiness in stroke patients, and to determine whether hope mediates the relationship between post-stroke fatigue and discharge readiness.

BACKGROUND

In stroke patients, inadequate discharge readiness has been found to correlate with higher readmission and mortality rates. Although previous qualitative studies have confirmed the impact of fatigue on discharge readiness, few studies explore the impact of post-stroke fatigue and hope on discharge readiness of stroke patients. Consequently, the current research on this relationship and its underlying mechanisms is still quite limited.

DESIGN

Cross-sectional study.

METHODS

Data were collected from 340 stroke patients. The research tools included demographic and disease characteristics, Discharge Readiness Assessment Scale for Stroke, Neurological Fatigue Index for Stroke and Herth Hope Index. The STROBE checklist was used to guide the presentation of this study.

RESULTS

Discharge readiness was negatively correlated with post-stroke fatigue and positively correlated with hope. Additionally, post-stroke fatigue was negatively correlated with hope. Post-stroke fatigue had a direct negative effect on discharge readiness, and it can also generate indirect effects through hope. Hope was the partial mediator between post-stroke fatigue and discharge readiness, explaining 55.8% of the total effect.

CONCLUSION

Discharge readiness of this population can be improved by reducing post-stroke fatigue and increasing hope. Therefore, effective management of post-stroke fatigue and hope will help improve discharge readiness.

RELEVANCE TO CLINICAL PRACTICE

It is recommended that nursing staff should monitor the occurrence and development of post-stroke fatigue in stroke patients, dynamically evaluate the patient's level of hope, and pay attention to the important role of positive psychological qualities in the outcome of discharge. If medical staff can formulate corresponding intervention measures based on the influence path of discharge readiness, then the discharge readiness of stroke patients can be improved.

Global prevalence estimates of poststroke fatigue: A systematic review and meta-analysis

BACKGROUND AND PURPOSE

Poststroke fatigue (PSF) is a common complication after stroke. However, information on the global prevalence of PSF and how this varies geographically and by population is lacking. Our aim was to examine the global prevalence of PSF and identify sources of heterogeneity in the published literature.

METHODS

Four medical databases (PubMed, EMBASE, PsycINFO, and Cochrane Database of Systematic Reviews) were searched from their inception to 28 February 2022. The Joanna Briggs Institute Critical Appraisal Instrument for studies reporting prevalence data (JBI) was used to assess the risk of bias (ROB) of the included studies. The primary outcome was the prevalence of PSF determined using a random-effects model. Subgroup analysis and meta-regression models were used to define the source of heterogeneity.

RESULTS

In all, 66 studies with 11,697 patients were included in this meta-analysis. The overall quality of the included studies was medium. The global pooled prevalence of PSF in stroke survivors was 46.79% (95% confidence interval (CI), 43.41-50.18%). The prevalence estimates of PSF based on the Fatigue Severity Scale (FSS), Multidimensional Fatigue Inventory-20 (MFI-20), and Fatigue Assessment Scale (FAS) were 47.44% (95% CI, 43.20-51.67%), 51.69% (95% CI, 44.54-58.83%), and 36.13% (95% CI, 23.07-49.18%), respectively. Prevalence rates of PSF were higher in females (53.19%; 95% CI, 46.46-59.92%), in hemorrhagic stroke (57.54%; 95% CI, 40.55-74.53%), in those with a college degree or higher (53.18%; 95% CI, 42.82-63.54%), and in those with unmarried or divorced status (59.78%; 95% CI, 44.72-74.83%).

CONCLUSIONS

The prevalence of PSF in stroke survivors is high, affecting almost half of all stroke sufferers. PSF rates were higher with female gender, being unmarried or divorced, having a higher educational level, and being hemorrhagic compared to ischemic stroke.

International research priority setting exercises in stroke: A systematic review

BACKGROUND

Agreeing on priority topics for stroke research can help make best use of limited funding, people, and time. Formal priority-setting exercises collate stakeholders' opinions to reach consensus on the most important research questions. Several stroke research priority setting exercises have been published. Exploring commonalities and differences between these exercises could bring a better understanding of priority research topics.

AIM

We collated and compared published stroke research priority setting exercises across international healthcare systems.

SUMMARY OF REVIEW

Multidisciplinary, electronic literature databases were searched from 2000 to 2021, using a validated search syntax. Inclusion criteria were: full article; stroke focus (any subtype); prioritization method described; and lists priorities for research. Priorities were extracted, coded, and assigned to categories using thematic analysis. The Nine Common Themes of Good Practice and the Reporting guideline for priority setting of health research checklists were used to assess methodological and reporting quality respectively. From 623 titles assessed, 14 studies were eligible for inclusion, including 2410 participants and describing 165 priorities. The majority of priority setting exercises were conducted in high-income countries (86%, n = 12 articles), published between 2011 and 2021 (64%, n = 9), and included views of healthcare professionals (57%, n = 8), and stroke survivors (50%, n = 7). Caregivers (n = 3, 21%) were under-represented. The James Lind Alliance priority setting method was most commonly used (50%, n = 7). Priorities were grouped into 10 thematic categories. Rehabilitation and follow-up was the most common priority theme (15%, n = 25 priorities), followed by psychological recovery (14%, n = 23), pathology (14%, n = 23), and caregivers and support (14%, n = 23). Priorities differed by year and case-mix (stakeholder group and demographics) of respondents. No article was judged high quality for all aspects of method or reporting. Common limitations were around inclusiveness and evaluation of the exercise.

CONCLUSION

Stroke research priorities are dynamic and context-specific. However, there was a common theme of prioritizing research that considered life after stroke. Future priority settings should consider the inclusion of nonindustrialized countries and stroke survivors with a range of impairments.

The HEADS: UP Development Study: Working with Key Stakeholders to Adapt a Mindfulness-Based Stress Reduction Course for People with Anxiety and Depression after Stroke

BACKGROUND

Following stroke, rates of mood disorder are and remain high at five years (anxiety 34.4%; depression 23%). Structured mindfulness-based stress reduction (MBSR) courses are effective in a range of health conditions, but stroke survivors find adherence challenging. We aimed to adapt a standard MBSR course specifically for people affected by stroke.

METHODS

We recruited stroke survivors and family members with symptoms of anxiety and/or depression to take part in a co-development study comprising two rounds of MBSR 'taster' sessions, followed by focus groups in which views were sought on the practices sampled. Data were collected in October 2017 and May 2018 and were analysed using framework analysis, informed adaptations to mindfulness materials and delivery.

RESULTS

Twenty-eight stroke survivors and seven family members participated. Nineteen (76%) stroke survivors had anxiety; 15 (60%) had depression. Five (71.4%) family members reported anxiety; n = 4 (57.1%) depression. Thirty participants attended the first round of taster sessions and focus groups; twenty (66%) the second and three (10%) were unable to attend either round. Framework analysis informed adaptations to course delivery, practices, and materials, ultimately resulting in a stroke-specific MBSR course, HEADS: UP (Helping Ease Anxiety and Depression after Stroke).

CONCLUSIONS

HEADS: UP may provide a feasible, appropriate, and meaningful self-management intervention to help alleviate symptoms of mood disorder.

Approaches to prioritising research for clinical trial networks: a scoping review

BACKGROUND

Prioritisation of clinical trials ensures that the research conducted meets the needs of stakeholders, makes the best use of resources and avoids duplication. The aim of this review was to identify and critically appraise approaches to research prioritisation applicable to clinical trials, to inform best practice guidelines for clinical trial networks and funders.

METHODS

A scoping review of English-language published literature and research organisation websites (January 2000 to January 2020) was undertaken to identify primary studies, approaches and criteria for research prioritisation. Data were extracted and tabulated, and a narrative synthesis was employed.

RESULTS

Seventy-eight primary studies and 18 websites were included. The majority of research prioritisation occurred in oncology and neurology disciplines. The main reasons for prioritisation were to address a knowledge gap (51 of 78 studies [65%]) and to define patient-important topics (28 studies, [35%]). In addition, research organisations prioritised in order to support their institution's mission, invest strategically, and identify best return on investment. Fifty-seven of 78 (73%) studies used interpretative prioritisation approaches (including Delphi surveys, James Lind Alliance and consensus workshops); six studies used quantitative approaches (8%) such as prospective payback or value of information (VOI) analyses; and 14 studies used blended approaches (18%) such as nominal group technique and Child Health Nutritional Research Initiative. Main criteria for prioritisation included relevance, appropriateness, significance, feasibility and cost-effectiveness.

CONCLUSION

Current research prioritisation approaches for groups conducting and funding clinical trials are largely interpretative. There is an opportunity to improve the transparency of prioritisation through the inclusion of quantitative approaches.

Prevalence of fatigue after stroke: A systematic review and meta-analysis

Background and Purpose

Post-stroke fatigue is a debilitating and long-lasting condition. However, there are uncertainties regarding its prevalence and variability between studies. This review aims to estimate the prevalence of fatigue and determine the factors responsible for its variation in the literature.

Methods

A systematic review was conducted for all published studies (search to November 2020) using AMED, CINAHL, EMBASE, MEDLINE, PsycINFO, SCOPUS and Web of Science. Papers were included if they recruited participants with stroke, used a validated scale to measure fatigue and were in English. Two reviewers screened and assessed the relevant studies for eligibility (n = 96). The included papers were appraised using the Joanna Briggs Institute (JBI) tool for prevalence studies, and data were extracted by one reviewer. To understand the variation in PSF prevalence between papers, data were pooled and analysed based on relevant methodological (e.g. time of assessment) or clinical factors (e.g. depression) using Review Manager 5.4 software.

Results

While 48 studies were included and summarised (N = 9004), only 35 were appropriate for the meta-analysis (N = 6851). The most frequently used tool to measure fatigue was the Fatigue Severity Scale (FSS) (n = 31). The prevalence was calculated with a cut-off point of four or more using FSS and resulted in an estimate of 48% (95% CI 42-53%). Time of assessment (<6 vs ≥6 months), stroke type (ischaemic vs haemorrhagic/subarachnoid haemorrhage) and geographical location (East Asia vs Europe) could explain the prevalence variation between studies.

Conclusions

Fatigue is prevalent among stroke survivors. This condition varies in terms of occurrence between studies; however, time of assessment, stroke type and geographical location might explain this variation. As this review estimates the overall burden of fatigue after stroke, it provides a useful indicator to inform policy, planning and healthcare professionals. Further efforts are required to investigate the mechanisms that lead to PSF, particularly in the groups that show high prevalence, in order to prevent or alleviate it.

Medication adherence early after stroke: using the Perceptions and Practicalities Framework to explore stroke survivors', informal carers' and nurses' experiences of barriers and solutions

Background

Secondary prevention medication after stroke reduces risk of recurrence, but adherence is often poor. Stroke survivors’, carers’ and nurses’ perspectives of early post-stroke medication adherence are unexplored.

Aim

The aim of this study was to explore stroke survivors’, carers’ and nurses’ views and experiences about adhering to medication early after post-stroke hospital discharge.

Methods

Qualitative individual and group interviews, utilising the Perceptions and Practicalities Framework, were employed. Nine people <2 months post-stroke, three carers and 15 nurses from one UK stroke unit participated. Interviews were digitally recorded, transcribed and thematically analysed.

Results

There were four main themes with two sub-themes. (1) Perceptions of medication taking after stroke. Factors affecting adherence included depression, imperceptible benefits and concerns about adverse effects. (2) Perceptions about those at higher risk of poor medication adherence. Nurses suggested that poor adherence might be more likely in those living alone or with previous non-adherence. (3) Practicalities of taking medication early after stroke; these included post-stroke disabilities, cognition, polypharmacy and lack of information. (4a) Practicalities of addressing poor medication adherence during the hospital stay. Solutions included multidisciplinary co-ordination, but nurses and stroke survivors described suboptimal use of opportunities to promote adherence. (4b) Practicalities of addressing poor medication adherence post-discharge. Solutions included modifications and support from carers, but stroke survivors reported difficulties in evolving systems for taking medications.

Conclusions

Stroke survivors and informal carers lack knowledge and support needed to manage medication early after discharge. Nurses’ opportunities to promote medication adherence are under-exploited. Medication adherence strategies to support stroke survivors early after discharge are needed.

The Development of an Early Intervention for Supporting Families of Persons With Acquired Brain Injuries: The SAFIR© Intervention

Families of persons with acquired brain injuries need to be supported from the early phase of hospitalization. To date, no known early family intervention is available for this population. Using the Medical Research Council Framework, we developed a new intervention based on the Calgary Assessment and Intervention Models that includes the family preferences, clinician's expertise, and the contextual resources. This paper aims to describe the complete development process including a scoping review, an assessment of families and clinicians' needs, an evaluation of the contextual resources, and an adaptation of the theoretical framework. Using a systemic perspective, we tailored the new intervention to involve the stakeholder's preferences. The result is an early family intervention named SAFIR^©, led by a clinical nurse specialist, including five core components and structured around three phases and a follow-up. The next steps will be focused on assessment of the clinical feasibility of this new intervention.

Predictors and short-term outcomes of post-stroke fatigue in initial phase of transition from hospital to home: A prospective observational study

AIM

To analyse the interactions of associated factors with post stroke fatigue (PSF) after discharge home and determine the predictors of PSF and their impact on stroke survivors.

DESIGN

A prospective observational study.

METHODS

A total of 94 patients with acute stroke were recruited between May 2019 -July 2020. The main outcomes were fatigue, depression, insomnia, sarcopenia, and health-related quality of life (HRQOL) and were assessed at admission and 1 month after discharge. Fatigue was measured using the Fatigue Assessment Scale. Depression and Insomnia were assessed using the Hospital Anxiety and Depression Scale-Depression and Insomnia Severity Index, respectively. Sarcopenia was measured using the SARC-F questionnaire, and HRQOL was assessed using the Short Form-8.

RESULTS

Acute phase PSF was an independent predictor of PSF after discharge home. Moreover the path analysis revealed that this effect is mediated through both the direct effect of acute-phase PSF on PSF after discharge home and through the indirect effect of interaction with pre-stroke SARC-F, acute phase depression, and acute phase insomnia, which remains a separate predictor of acute-phase PSF. In total, 17% of the survivors had persistent PSF. Persistent PSF was significantly associated with depression, insomnia, sarcopenia, and a lower quality of life scores.

CONCLUSIONS

Post-stroke fatigue may occur in the acute phase and persists after discharge, it will not only affect later depression, insomnia, and quality of life, but also sarcopenia.

IMPACT

Acute phase PSF was found to be an independent predictor of PSF after discharge home. In addition, the interaction with pre-stroke SARC-F, acute phase depression and insomnia had an indirect connection with PSF after discharge home, which remains a separate predictor of acute-phase PSF. Thus, early assessment and management of mental status, sleep problems, and sarcopenia during hospitalization might be an important step in post-stroke rehabilitation and home transition.

Implementing Supported Self-Management in Community-Based Stroke Care: A Secondary Analysis of Nurses' Perspectives

The provision of supported self-management (SSM) is recommended in contemporary guidelines to address the longer-term needs and outcomes of stroke survivors and their families, yet its implementation across stroke pathways has been inconsistent. This paper presents a secondary analysis of qualitative data, which aims to identify and offer insight into the challenges of implementing SSM from the perspectives of community stroke nurses (n = 14). The findings revealed that the implementation of SSM in stroke is influenced by factors operating at multiple levels of the healthcare system. Contextual challenges arise because of different understandings and interpretations of what SSM is, what it comprises and professionals' perceptions of their roles in its implementation in practice. A professionally controlled, one-size-fits-all model of SSM continues to be reinforced within organizations, offering few opportunities for nurses to deliver contextually tailored and person-centred SSM. In conclusion, there are many professional concerns and organizational tensions that need to be addressed across multiple layers of the healthcare system to achieve the consistent implementation of contextually tailored and person-centred SSM following a stroke. Attempts to address these challenges will help to narrow the gap between policy and practice of implementing SSM, ensuring that stroke survivors and families benefit from SSM in the longer-term.

Nursing research priorities based on CINAHL database: A scoping review

Aim

To analyse nursing research based on the CINAHL database to identify research priorities for nursing.

Design

A scoping literature review was conducted. The CINAHL Plus (EBSCO) Full Text was searched between 2012-2018.

Methods

Out of 1522 original publications, 91 fulfilled the inclusion criteria. The Joanna Briggs Institute critical appraisal tools were applied. Data were analysed by a thematic analysis method.

Results

A strong emphasis should be put on development and evaluation of nursing theories and, in addition, randomized controlled trial studies, meta-synthesis, experimental and intervention studies are needed in nursing research. Development of competencies and skills in the nursing profession ought to be studied more extensively and research should be focused on variety fields of nursing practice.

Non-Pharmacological Interventions for Post-Stroke Fatigue: Systematic Review and Network Meta-Analysis

Post-stroke fatigue (PSF) is one of the most serious sequelae, which often interferes with the rehabilitation process and impairs the functional recovery of patients. Due to insufficient evidence, it is unclear which specific pharmacological interventions should be recommended. Therefore, in this paper, we compare the effectiveness of non-pharmacological interventions in PSF. A systematic review and network meta-analysis of randomized controlled trials were performed using EMBASE, MEDLINE, CINAHL, Cochrane library, ClinicalTrials.gov, CNKI, and CQVIP, from inception to January 2018, in the English and Chinese languages. RCTs involving different non-pharmacological interventions for PSF with an outcome of fatigue measured using the Fatigue Severity Scale were included. Multiple intervention comparisons based on a Bayesian network are used to compare the relative effects of all included interventions. Ten RCTs with eight PSF non-pharmacological interventions were identified, comprising 777 participants. For effectiveness, most interventions did not significantly differ from one another. The cumulative probabilities of the best non-pharmacological intervention for fatigue reduction included Community Health Management (CHM), followed by Traditional Chinese Medicine (TCM) and Cognitive Behavioral Therapy (CBT). Network meta-analysis based on data from the selected RCTs indicated that the eight PSF non-pharmacological interventions shared equivalent efficacy, but CHM, TCM, and CBT showed potentially better efficacy. In the future, fatigue needs to be recognized and more accurate assessment methods for PSF are required for diagnosis and to develop more effective clinical interventions.

Delirium in patients with ischaemic and haemorrhagic stroke: findings from a scoping review

BACKGROUND

Delirium is a complex syndrome characterised by disturbances in attention and awareness, associated with alterations in cognitive functions, which can emerge in a time frame of hours or days and tend to fluctuate in severity over time. Delirium is a clinical manifestation of the brain's vulnerability and diminished resilience to insult. Stroke patients are particularly vulnerable to delirium episodes.

AIMS

The aim of this study was to map: (a) studies focused on ischaemic or haemorrhagic post-stroke delirium; (b) factors that have been investigated as being possibly associated with post-stroke delirium; and (c) outcomes that have been studied to date.

METHODS

A scoping review was performed. Medline, CINAHL, Cochrane Database of Systematic Reviews, PsycINFO and Scopus databases were searched. Eligible studies were those: (a) exploring any variable regarding delirium in patients with stroke; (b) involving adults; (c) as primary studies; (d) written in English; and (e) published before April 2017.

RESULTS

To date 25 studies have been published, mainly prospective or cohort studies. The most commonly studied predisposing factors have been the older age, gender, aetiology of the stroke and its location, and the presence of previous cognitive decline/dementia. The most studied precipitating factors to date have been pneumonia, urinary tract infections and symptoms of neglect. Functional dependence, length of inhospital stays, post-stroke cognitive impairments or dementia, short and long-term mortality have been the most studied post-stroke delirium outcomes.

CONCLUSIONS

Studies across different clinical settings, also at the international level, including more female patients and a wider range of ages should be designed in order to improve the evidence available to develop specific clinical guidelines. Standardised frameworks of research addressing the great variability of methods and measures used in the field should be established at the international level by clinicians and researchers' experts in the field.

How to do a systematic review

High quality up-to-date systematic reviews are essential in order to help healthcare practitioners and researchers keep up-to-date with a large and rapidly growing body of evidence. Systematic reviews answer pre-defined research questions using explicit, reproducible methods to identify, critically appraise and combine results of primary research studies. Key stages in the production of systematic reviews include clarification of aims and methods in a protocol, finding relevant research, collecting data, assessing study quality, synthesizing evidence, and interpreting findings. Systematic reviews may address different types of questions, such as questions about effectiveness of interventions, diagnostic test accuracy, prognosis, prevalence or incidence of disease, accuracy of measurement instruments, or qualitative data. For all reviews, it is important to define criteria such as the population, intervention, comparison and outcomes, and to identify potential risks of bias. Reviews of the effect of rehabilitation interventions or reviews of data from observational studies, diagnostic test accuracy, or qualitative data may be more methodologically challenging than reviews of effectiveness of drugs for the prevention or treatment of stroke. Challenges in reviews of stroke rehabilitation can include poor definition of complex interventions, use of outcome measures that have not been validated, and poor generalizability of results. There may also be challenges with bias because the effects are dependent on the persons delivering the intervention, and because masking of participants and investigators may not be possible. There are a wide range of resources which can support the planning and completion of systematic reviews, and these should be considered when planning a systematic review relating to stroke.
