Comprehensive Stroke Care and Outcomes: Time for a Paradigm Shift

Circulatory factors in stroke protection and recovery

Over the past decade, the management of acute ischemic stroke has undergone a paradigm shift, especially a longer time-window and a wider indication for endovascular treatments. However, many patients still have long-term dysfunction despite the best medical care at present. Based on findings from innovative proteomic and transcriptomic technologies, researchers have identified an array of novel or previously underappreciated circulatory factors that play pivotal roles in mediating post-injuries brain communication. Thus, the previous concept of the brain as a privileged compartment isolated from the rest of the body has been replaced by the novel consensus that brain bidirectionally interacts with the other organs after brain diseases. In this review, we make a summary of several axes that connect the brain with the rest of the body after stroke. More importantly, we summarize several circulatory factors that play pivotal roles in fostering post-stroke functional recovery in the chronic stage. Special attention is given to the instrumental role of circulatory signals, positing them as significant contributors to the complex process of brain function recovery and as translational therapeutic targets for ischemic stroke in future studies.

The effect of a healthy lifestyle on reducing the utilisation of healthcare professionals and prescription medications among stroke survivors: a longitudinal investigation using linked administrative data

PURPOSE

The aim of the study was to examine whether a healthy lifestyle was associated with reduced utilisation of healthcare professionals and/or prescription medications for stroke survivors.

METHODS

The study utilised data obtained from the 45 and Up Study, linked to the Medicare claims and Pharmaceutical Benefits Scheme data. The outcome variables were the number of times a person received care from a range of healthcare professions and the number of different prescription medications used by participants. The risk factors were smoking, alcohol consumption, physical activity, and supplement use. Generalised Estimating Equation models were employed to assess the longitudinal association between an outcome variable and risk factors.

RESULTS

Stroke survivors who engaged in moderate-to-high levels of physical activity were significantly less likely to receive care from a general practitioner, a nurse, and an allied health professional, as well as to take blood-thinning medications. Stroke survivors who smoked were more likely to receive care from a specialist doctor. Moreover, stroke survivors who consumed supplements were more likely to receive care from an allied health professional.

CONCLUSION

The findings carry substantial implications for stroke rehabilitation and secondary prevention, highlighting the positive effects of moderate-to-high physical activity and the associated risks of smoking.

Exploring factors influencing the consistent adoption of a post-stroke upper extremity outcome measure using Normalisation Process Theory

BACKGROUND

Stroke rehabilitation guidelines recommend using outcome measures like the Fugl-Meyer Assessment for Upper Extremity (FMA-UE) to assess post-stroke upper extremity function. However, integrating such outcome measures into routine clinical practice remains challenging, highlighting the need to understand factors affecting their implementation in evolving healthcare models.

OBJECTIVE

Our study aimed to identify the barriers and facilitators to sustain the routine use of the FMA-UE among hospital-based occupational therapists (OTs) using a theory-driven approach.

METHODS

Employing a mixed-method sequential exploratory study design rooted in Normalisation Process Theory (NPT), we gathered quantitative data through a validated survey followed by qualitative insights analysed with directed content analysis from focus group discussions involving occupational therapists from four hospitals.

RESULTS

Survey findings (n = 34) revealed barriers primarily associated with NPT constructs of collective action and coherence. Facilitators were linked to the cognitive participation construct. Key barriers identified in focus groups included insufficient coaching, competing priorities, and perceived limited value of the FMA-UE. Facilitators included legitimation of therapists' role in outcome measurements and an open learning culture.

CONCLUSIONS

Through a theory-based approach, we identified barriers and facilitators to sustain the routine of the FMA-UE. Our findings offer insights for designing implementation strategies to embed the FMA-UE into routine practice, supporting its sustained use in stroke rehabilitation.

Examining the Efficacy of the Telehealth Assessment and Skill-Building Kit (TASK III) Intervention for Stroke Caregivers: Protocol for a Randomized Controlled Clinical Trial

BACKGROUND

Stroke is a leading cause of serious, long-term disability and has a sudden onset. Upon discharge to the home setting, families are thrust into providing care, often without sufficient training from health care providers. Aligned with current patient and caregiver guidelines, the Telehealth Assessment and Skill-Building Kit (TASK III) is a nurse-led intervention designed to empower caregivers to address their own needs and those of the survivor using innovative skill-building strategies.

OBJECTIVE

This study aims to test the short-term (immediately after the intervention at 8 wk) and long-term (12, 24, and 52 wk) efficacy of the TASK III intervention, compared with an information, support, and referral (ISR) group, to improve caregiver life changes (ie, changes in physical health, physical functioning, emotional well-being, and general health) as a result of providing care.

METHODS

A randomized controlled clinical trial design will be used with baseline data collection from 296 family caregivers by telephone after the stroke survivor is discharged home. Caregivers randomly assigned to the ISR group (n=148, 50%) will receive information from the American Heart Association about stroke family caregiving. Caregivers randomly assigned to the TASK III group (n=148, 50%) will receive a TASK III resource guide and information from the American Heart Association. Both groups will receive 8 weekly calls from a nurse, with a booster call a month later. Outcomes will be assessed by blinded data collectors at 8, 12, 24, and 52 weeks. The primary outcome (at 8 wk) is caregiver life changes measured by the Bakas Caregiving Outcomes Scale. Secondary outcomes are depressive symptoms; other symptoms (eg, stress, fatigue, sleep, pain, and shortness of breath); unhealthy days; diet; exercise; and self-reported health care use. Mediators are task difficulty, threat appraisal, and self-efficacy. Program evaluation outcomes (satisfaction and technology ratings) will also be analyzed.

RESULTS

The trial was registered on March 10, 2022. Enrollment and random assignment of the first participant was on November 30, 2022, with an anticipated completion of recruitment by November 30, 2025. Completion of the primary end point data analysis is anticipated by August 31, 2026, with results expected to be reported on ClinicalTrials.gov by April 1, 2027. As of October 9, 2024, a total of 198 (66.9% of the proposed total sample of 296) family caregivers have been enrolled and randomly assigned to the TASK III group (n=98, 49.5%) or the ISR group (n=100, 50.5%). The last update was performed on January 25, 2024.

CONCLUSIONS

If the TASK III intervention is shown to be efficacious in the proposed randomized controlled clinical trial, our next goal will be to translate TASK III into ongoing stroke systems of care, providing a tremendous public health impact.

Quantitative Electroencephalogram Might Improve the Predictive Value of Prognosis 6 Months After Discharge in Acute Ischemic Stroke

Background: As a leading cause of severe morbidity, acute ischemic stroke (AIS) necessitates precise prognostic evaluation to inform critical treatment strategies. Recent advancements have identified quantitative electroencephalography (qEEG) as a pivotal instrument in refining prognostic accuracy for AIS. This investigation aimed to construct a robust prognostic model, anchored in qEEG parameters, to enhance the precision of clinical prognosis 6 months after discharge in AIS patients. Methods: In a retrospective observational study, we analyzed AIS cases from January 2022 to March 2023. Data encompassing demographic profiles, clinical manifestations, qEEG findings, and modified Rankin Scale (mRS) assessments were evaluated for 109 patients with AIS. These metrics were instrumental in developing prognostic models, segregating outcomes into either favorable (mRS: 0-2) or unfavorable categories (mRS: 3-6) at 6 months post-discharge. Prognostic models were developed using clinical and qEEG parameters. Results: The formulation of two distinct prognostic models was predicated on an integration of baseline clinical data (age, unilateral limb weakness, ataxia and red blood cell count) and specific qEEG metrics (T3-P3 (TAR) and T4-P4 (TAR)). The synthesis of these models culminated in the Prognostic Model 3, which exhibited a marked enhancement in prognostic accuracy, as evidenced by an area under the curve (AUC) of 0.8227 (95% CI: 0.7409-0.9045), thereby signifying a superior prediction of AIS prognosis 6 months after discharge relative to the individual models. Conclusion: Quantitative EEG, especially increased theta/alpha power ratio (TAR), might improve the prediction of prognosis 6 months after discharge of acute ischemic stroke in clinical practice.

Contribution of cognitive status on admission to mobility and balance at discharge from acute rehabilitation for stroke

Acute inpatient rehabilitation is crucial for improving mobility and balance for individuals with stroke. A potentially important factor in the recovery of mobility and balance is cognition. The purpose of this study was to determine the effect of cognition on mobility and balance in acute stroke rehabilitation. This was a longitudinal cohort study based on an inpatient rehabilitation unit at a large academic medical center. Participants were individuals with stroke admitted to acute rehabilitation after an acute care hospital stay ( N  = 281). Demographic data and predictor variables were collected on admission to the unit. Outcomes were collected at discharge from the unit. Multiple regression analyses were used to determine the associations between cognition (Montreal Cognitive Assessment) on mobility (Functional Independence Measure mobility subscale) and balance (Berg Balance Scale). Subtests from the Montreal Cognitive Assessment were also examined to determine if specific dimensions of cognition could predict balance after controlling for covariates. Dominance analysis was used to determine the relative importance of baseline predictors. In separate models, cognition was a significant predictor of mobility ( B  = 0.19) and balance ( B  = 0.28) at discharge after adjusting for admission mobility and balance, as well as age, sex, and length of stay. The most important predictors in both models were baseline mobility and balance, but cognition contributed to the models independently of baseline scores. Cognition was generally more important than age and sex while about equally important as length of stay. In separate models, the visuospatial/executive ( B  = 0.42) and the delayed recall ( B  = 0.37) subtests were also significant predictors of mobility. The models' most important predictors were baseline mobility and balance scores. Cognition is a clinically relevant predictor of mobility and balance in acute stroke rehabilitation. Specific dimensions of cognition, such as executive function, visuospatial function, and delayed recall, may be especially important. Cognitive challenges and meta-cognitive strategies should be included in mobility and balance tasks when possible. Studies that evaluate the efficacy of dual-task training and meta-cognitive approaches are needed.

Racial and ethnic disparities in post-acute care service utilization after stroke

Evidence examining disparities in post-acute care (PAC) utilization among various racial and ethnic groups after stroke and the influence of social determinants of health (SDOH) in these decisions is lacking. Thus, we searched the literature from January 2000 to November 2023 regarding PAC among individuals after stroke through: 1) Pubmed, 2) Scopus, 3) Web of Science, 4) Embase, and 5) CINAHL. We found 14 studies. Black individuals were more likely than White individuals to be discharged home with home health (HH) and skilled nursing facilities (SNF). Hispanic individuals were more likely than White individuals to be discharged home with HH, but less likely to be discharged to institutions. Lower socioeconomic status, Medicaid insurance, urban residence, area PAC supply and hospital characteristics were associated with increased institutional discharges among racial and ethnic minority individuals. Future policy should improve access to appropriate PAC commensurate with an individual's medical/social complexity.

Clinical and neurophysiological predictors of the functional outcome in right-hemisphere stroke

OBJECTIVE

The aim of the present study is to examine the relationship between EEG measures and functional recovery in right-hemisphere stroke patients.

METHODS

Participants with stroke (PS) and neurologically unimpaired controls (UC) were enrolled. At enrolment, all participants were assessed for motor and cognitive functioning with specific scales (motricity index, trunk control test, Level of Cognitive Functioning, and Functional Independence Measure (FIM). Moreover, EEG data were recorded. At discharge, participants were re-tested with the FIM RESULTS: Powers in the delta, theta, alpha, and beta bands and connectivity within the fronto-parietal network were compared between groups. Then, the between-group discriminative EEG measures and the motor/cognitive scales were used to feed a machine learning algorithm to predict FIM scores at discharge and the length of hospitalization (LoH). Higher delta, theta, and beta and impaired connectivity were found in PS compared to UC. Moreover, motor/cognitive functioning, beta power, and fronto-parietal connectivity predicted the FIM score at discharge and the LoH (accuracy=73.2 % and 85.2 % respectively).

CONCLUSIONS

Results show that the integration of motor/cognitive scales and EEG measures can reveal the rehabilitative potentials of PS predicting their functional outcome and LoH.

SIGNIFICANCE

Synergistic clinical and electrophysiological models can support rehabilitative decision-making.

Palliative and End-of-Life Care in Stroke: A Scientific Statement From the American Heart Association

OBJECTIVE

To provide an update on palliative care needs specific to stroke and provide key points for clinicians and health care systems caring for patients with stroke and their families.

METHODS

Members of the writing group were chosen to represent the multidisciplinary team of professionals who care for people who have had a stroke. Each member was assigned a topic within their area of expertise, reviewed the literature, and drafted content with a focus on the past decade to complement the 2014 American Heart Association scientific statement on palliative and end-of-life care in stroke.

RESULTS

Stroke has multidimensional effects on patients and their families because of threats to personhood, prognostic uncertainty, and the need to adapt to functional changes after stroke. Palliative care has evolved as both a specialty and a skillset with a goal to improve communication about goals of care and quality of life for patients and their families that emphasizes a holistic, all-person approach. After stroke, palliative care needs (eg, to address pain and physical, emotional, psychosocial, and spiritual distress) are insufficiently addressed by current models of care. Integrating palliative care principles is fundamental in all stages of stroke and should include strategies to improve communication about prognosis and goals of care, address psychosocial needs such as coping with loss, navigating complex health care systems, and preparing for death when necessary. We also review strategies to address the substantial inequities that exist across sociodemographic and regional strata in the use of life-sustaining treatment and access to specialists in stroke or palliative care.

CONCLUSIONS

Palliative care needs are common after stroke and should be addressed throughout the illness continuum. Research is urgently needed.

Cognitive impairment after hemorrhagic stroke is less common in patients with elevated body mass index and private insurance

BACKGROUND

Hemorrhagic stroke survivors may have cognitive impairment. We sought to identify preadmission and admission factors associated with cognitive impairment after hemorrhagic stroke.

DESIGN

Patients with nontraumatic intracerebral or subarachnoid hemorrhage (ICH or SAH) were assessed 3-months post-bleed using the Quality of Life in Neurological Disorders (Neuro-QoL) Cognitive Function short form. Univariate and multivariate analysis were used to evaluate the relationship between poor cognition (Neuro-QoL t-score ≤50) and preadmission and admission factors.

RESULTS

Of 101 patients (62 ICH and 39 SAH), 51 (50 %) had poor cognition 3-months post-bleed. On univariate analysis, poor cognition was associated with (p < 0.05): age [66.0 years (52.0-77.0) vs. 54.5 years (40.8-66.3)]; private insurance (37.3 % vs. 74.0 %); BMI > 30 (13.7 % vs. 34.0 %); and admission mRS score > 0 (41.2 % vs. 14.0 %), NIHSS score [8.0 (2.0-17.0) vs. 0.5 (0.0-4.0)], and APACHE II score [16.0 (11.0-19.0) vs. 9.0 (6.0-14.3)]. On multivariate analysis, poor cognition was associated with mRS score > 0 [OR 4.97 (1.30-19.0), p = 0.019], NIHSS score [OR 1.14 (1.02-1.28), p = 0.026], private insurance [OR 0.21 (0.06-0.76), p = 0.017] and BMI > 30 [OR 0.13 (0.03-0.56), p = 0.006].

CONCLUSIONS

Cognitive impairment after hemorrhagic stroke is less common in patients with BMI > 30 and private insurance. Heightened surveillance for non-obese patients without private insurance is suggested. Additional investigation into the relationship between cognition and both BMI and insurance type is needed.

Risk factors, mechanisms, and clinical outcomes of stroke in young adults presenting to a North Central London stroke service: UCL Young Stroke Systematic Evaluation Study (ULYSSES)

INTRODUCTION

Stroke incidence in younger adults is increasing worldwide yet few comprehensive studies exist from a UK population. We investigated the risk factors, mechanisms, functional outcome and stroke recurrence rate in a cohort of young adults with stroke.

PATIENTS AND METHODS

We included consecutive patients (<55 years) with ischaemic stroke or intracerebral haemorrhage (ICH) admitted to the University College London Hospitals Hyperacute Stroke Unit between 2017 and 2020. Ischaemic stroke was classified using Trial of Org 10172 in Acute Stroke Treatment (TOAST) criteria and ICH using modified CLAS-ICH criteria. Multivariable logistic regression was performed to identify predictors of unfavourable functional outcome (modified Rankin Scale [mRS] > 1) at 6 months.

RESULTS

Five hundred fifty-two patients were included (median age 47, IQR 41-51; 33% female; 76% ischaemic stroke). Common risk factors included dyslipidaemia (57%), hypertension (40%), and cigarette smoking (34%). Ischaemic stroke was mostly due to cardioembolism (22%). Probable cerebral small vessel disease was the most frequent ICH aetiology (53%). Unfavourable functional outcome was prevalent in 50% at 6 months and was associated with ICH (OR 2.02, 95%CI 1.14-3.58, p = 0.017), female sex (OR 1.62, 95%CI 1.03-2.55, p = 0.037), admission stroke severity (per point increase, OR 1.11, 95%CI 1.07-1.16, p < 0.001) and pre-morbid mRS 2-5 (OR 3.16; 95%CI 1.11-9.03, p = 0.032). 4.4% had a recurrent stroke within 6 months.

DISCUSSION AND CONCLUSION

Traditional cardiovascular risk factors are common in young adults with stroke. Unfavourable functional outcome is associated with female sex, ICH, severe stroke and pre-morbid disability. These findings can inform national stroke prevention and rehabilitation strategies.

Implementation of the virtual transitional care stroke intervention for older adults with stroke and multimorbidity: A qualitative descriptive study

Background

Older adults with stroke and multimorbidity experience frequent care transitions, which are often poorly coordinated and fragmented. We conducted a pragmatic randomized controlled trial (RCT) to test the implementation and effectiveness of the Transitional Care Stroke Intervention (TCSI), a 6-month, multi-component, evidence-informed intervention to support older adults with stroke and multimorbidity using outpatient stroke rehabilitation services. The TCSI was designed to support self-management, improve health outcomes, and enhance the quality and experience of care transitions.

Objective

To explore the facilitators and challenges to implementing the TCSI, from the perspective of healthcare providers (HCPs) (n = 12) and Managers (n = 3).

Methods

Data collection and analysis were guided by the Consolidated Framework for Implementation Research (CFIR). Data were collected from study documents, individual and group interviews conducted with HCPs and a Care Coordinator, and surveys from managers. Data were analyzed using thematic analysis.

Results

Intervention implementation was facilitated by: a) strong collaborative and interdependent HCP team relationships, b) dedicated resources (funding, staffing) to support intervention delivery, c) training and ongoing support, customized to individual HCP needs, d) organizational readiness, strong leadership, and effective champions, e) structures to facilitate virtual information-sharing, and f) regular monitoring of intervention implementation. Implementation challenges included: a) COVID-19 related challenges (staff turnover, community service disruptions), b) poor communication with community service providers, c) documentation burden (intervention-related), and d) virtual care delivery.

Conclusions

This research enhances understanding of the diversity of factors influencing implementation of the TCSI, and the conditions under which implementation is more likely to succeed.

A Comparison of Rural and Urban Differences in Geographic Proximity to Outpatient Stroke Rehabilitation Services in Tennessee

PURPOSE

Great travel distances and long travel times can be barriers to outpatient stroke rehabilitation services (OSR) receipt, but there is limited information on differences in proximity to specific OSR services between urban and potentially medically underserved rural areas. Accordingly, we compared travel distance and time to the nearest service for different OSR services between rural and urban counties in Tennessee.

METHODS

We conducted data scraping on Google Maps to locate Tennessee facilities offering any of the 13 American Heart Association recognized OSR services. We conducted manual validation by calling located facilities and visiting facility websites. We used the Wilcoxon rank sum test to examine if mean travel distance and time to a specific OSR service differed significantly between rural and urban counties.

RESULTS

All OSR services but audiology were available in Tennessee. In rural counties, social work had the highest median of mean travel distance (135.2 km), chaplaincy the highest median of mean travel time (113.5 min), and physical therapy the lowest distance (37.7 km) and time (36.3 min). Except for social work, rural counties had significantly higher travel distance and time than urban counties ( P < .01) for all OSR services.

CONCLUSIONS

Rural Tennessee counties had significantly higher travel distance and time for almost all OSR services compared to urban areas. These findings from a largely rural state with high stroke risk factor prevalence suggest that additional focus on establishing maximum travel limits for OSR are warranted to overcome transportation barriers to enhance post-stroke services access in similar areas.

Exploring the experiences of an exercise-based telerehabilitation program among Canadian community-dwelling adults with stroke

PURPOSE

Telerehabilitation is emerging as a means for delivering stroke rehabilitation to address unmet lower extremity rehabilitation needs. However, there is currently limited and low-quality evidence supporting the use telerehabilitation interventions for lower extremity recovery after stroke. Thus, we developed an exercise-based telerehabilitation program (TRAIL) for safe and effective promotion of lower extremity function after stroke. This study reports on the qualitative findings from the feasibility study of the TRAIL program.

METHODS

An interpretive description methodology and inductive thematic analysis approach were undertaken. One-on-one semi-structured interviews were conducted on a subset of participants who completed the TRAIL feasibility study. Participants were recruited via email and enrolled into the study based on pre-determined purposeful sampling strategies.

RESULTS

Ten participants (6 men, 4 women) completed a semi-structured interview. Two main themes emerged: (i) TRAIL ingredients for success and (ii) telerehabilitation is a viable option for stroke rehabilitation.

CONCLUSION

Exercise-based telerehabilitation appears to be well-received by men and women post-stroke when social support, professional guidance, and program resources are offered. TRAIL may also prolong the continuum of care that individuals receive once they are discharged back into the community, and contribute to improvements in mobility, lower extremity strength and balance.

Family's Caregiving Status and Post-Stroke Functional Recovery During Subacute Period from Discharge to Home: A Retrospective Study

Background/Objectives: Family members, often informal caregivers, play a crucial role in providing home care for stroke survivors. The period following discharge to home after receiving acute stroke management in a hospital includes the subacute phase of stroke and remains critical to the recovery of stroke patients. This study evaluated the association between family caregiving and post-stroke functional recovery after discharge to home. Methods: Data from 402 patients with stroke were obtained from the Korea University Ansan Hospital Stroke Center from January 2019 to May 2022. The family's caregiving status was evaluated for family burden and supportable environment in the home. This study's outcome of interest was the modified Rankin Scale (mRS) at discharge to home and three months after stroke onset. The repeated mRS scores were analyzed using the Linear Mixed Model. Results: Median days from discharge to 3 months after stroke onset was 81.0 days. The median score of mRS at discharge was 2.0, and the score at three months after stroke onset was 2.0. The distribution of mRS score 0-2 was 60.9% at discharge and 72.1% at three months after stroke onset. In Linear Mixed Models after adjustments with covariables, the family's caregiving status was positively associated with repeated mRS scores (β = 0.17; 95% confidence interval = 0.11, 0.23; p < 0.001). Conclusions: These findings suggest that family caregiving to patients with stroke might be associated with post-stroke functional recovery within the period from discharge to home until three months after stroke onset.

Hypertensive retinopathy can predict stroke: A systematic review and meta-analysis based on observational studies

OBJECTIVE

The aim of this study was to determine whether hypertensive retinopathy is specifically associated with stroke.

METHODS

The relevant studies published until December 18, 2023 were identified as well as selected from PubMed, Embase, Web of science, WanFang, CNKI, VIP, and CBM databases. Hazard ratios (HRs), risk ratios (RRs), and 95% confidence intervals (CIs) were combined.

RESULTS

Six cohort studies were included in this analysis. Patients with hypertensive retinopathy exhibited a significantly higher overall risk of stroke than those without hypertensive retinopathy (RR=1.46, 95%CI: 1.29-1.65). When subgroups were analyzed by region, patients with hypertensive retinopathy in Asia had the highest risk of stroke (RR=1.53, 95%CI: 1.33-1.77). In addition, among the different severity grades of hypertensive retinopathy, the risk of stroke in patients with grade 3/4 hypertensive retinopathy (RR=1.82, 95%CI: 1.41-2.34) was observed to be higher than that in patients with grade 1/2 hypertensive retinopathy (RR=1.43, 95%CI: 1.27-1.61).

CONCLUSIONS

Hypertensive retinopathy was found to be associated with an increased risk of stroke. Thus, it is necessary to include retinopathy in the routine screening of patients with hypertension.

Challenges in Accessing Community-Based Rehabilitation and Long-Term Care for Older Adult Stroke Survivors and Their Caregivers: A Qualitative Study

Background and Objectives

While extensive research has examined the rehabilitation challenges faced by stroke survivors, there is limited literature addressing the difficulties encountered by older adult stroke survivors and their caregivers in accessing rehabilitation and long-term care within the Chinese community. This study aimed to investigate the specific challenges related to access, quality, and coordination of rehabilitation and long-term care experienced by older adult stroke survivors and their caregivers within the Chinese community.

Methods

A qualitative phenomenological design was employed to explore the lived experiences of stroke survivors and their caregivers within the Chinese community. A purposive sampling method was used to recruit participants from June to August 2023. Participants engaged in face-to-face semi-structured interviews. The data were analyzed using an inductive thematic analysis approach to identify and understand key themes and sub-themes.

Results

The study involved 38 participants, consisting of 21 older adult stroke survivors (13 males, 8 females) and 17 family caregivers (7 males, 10 females), recruited from five Chinese community health service stations. The analysis identified four distinct themes and 11 sub-themes that encapsulated the challenges faced by participants. These themes include (1) Difficulties in accessing medical services (insufficient medical resources, lack of rehabilitation resources, and time-consuming processes), (2) Challenges in daily life (inconvenience in daily mobility, inadequate financial support, and difficulties in applying for home care services), (3) Psychosocial stress (loneliness, powerlessness, and worry about burdening others), (4) Insufficient information (lack of awareness of available community services, and limited public health education activities).

Conclusion

Older adult stroke survivors and their caregivers in Chinese communities face significant challenges. To improve their well-being and quality of life, it is crucial to address these challenges through enhanced access to healthcare, better support for daily living, and more effective information dissemination. Meeting these needs requires a coordinated effort from healthcare providers, community stakeholders, and policymakers to develop and implement effective, long-term care solutions.

Assessment of Motor Imagery and Its Relationship to Functional Impairment in Post-Stroke Patients: A Descriptive Cross-Sectional Study

Background: Motor and cognitive sequelae are common in patients who have experienced a stroke. Recent advances in neuroscience have enabled the development of novel therapeutic approaches, such as motor imagery, which facilitate motor learning. The objective of this study is to examine the relationship between implicit and explicit motor imagery abilities and their correlation with functional impairment in post-stroke patients. Methods: A descriptive cross-sectional study was conducted with 36 patients who had experienced a stroke between March 2008 and March 2023. The capacity to generate both implicit and explicit motor imagery and to perform physical functions was evaluated. The relationship between implicit and explicit motor imagery measures was investigated using Pearson's correlation coefficient. The factorial structure, which encompasses the capacity to generate motor imagery, whether implicit or explicit, and physical function, was subjected to analysis. Results: A correlation was identified between the time taken to identify images and the accuracy of this process, with the right hand (R = 0.474), the left hand (R = 0.568), and the left foot (R = 0.344) all demonstrating significant associations. Additionally, a notable correlation was observed between the two subscales of the KVIQ-10 scale (R = 0.749). No association was identified between the capacity to generate implicit and explicit motor imagery. Two- and three-factor solutions were obtained for the right and left hemibodies, respectively. On both sides, accuracy in identifying images and physical function constituted a single factor, while time to generate images for both hands and feet constituted a second factor. Conclusions: In conclusion, no significant data were reported regarding the association between the capacity to generate implicit and explicit motor imagery in the studied sample. However, the ability to generate implicit motor imagery was related to physical function, suggesting that it may serve as a screening criterion for implementing specific therapeutic approaches in post-stroke patients.

Rehabilitation Transition Program to Improve Community Participation Among Stroke Survivors: A Randomized Clinical Trial

Importance

Interventions are needed to support the long-term needs of stroke survivors when they transition from inpatient rehabilitation to home, where they face new home and community environmental barriers.

Objective

To compare the efficacy of a novel, enhanced rehabilitation transition program with attentional control to improve community participation and activity of daily living (ADL) performance and to reduce environmental barriers in the home and community after stroke.

Design, Setting, and Participants

This phase 2b, parallel randomized clinical trial assessed patients 50 years or older who had experienced an acute ischemic stroke or intracerebral hemorrhage, were independent in ADLs before stroke, and planned to be discharged home. Patients were assessed at an inpatient rehabilitation facility in St Louis, Missouri, and their homes from January 9, 2018, to December 20, 2023.

Intervention

Community Participation Transition after Stroke (COMPASS), including home modifications and strategy training.

Main Outcomes and Measures

The primary outcome was community participation (Reintegration to Normal Living Index). Secondary outcomes were daily activity performance (Stroke Impact Scale ADL domain and the In-Home Occupational Performance Evaluation [I-HOPE] activity, performance, and satisfaction scores) and environmental barriers in the home (I-HOPE environmental barriers score).

Results

A total of 185 participants (mean [SD] age, 66.3 [9.0] years; 105 [56.8%] male) were randomized (85 to the COMPASS group and 100 to the control group). The COMPASS and control participants experienced similar improvements in community participation by 12 months, with no significant group (mean difference, 0.3; 95% CI, -4.6 to 5.2; P = .91) or group × time interaction (between-group differences in changes over time, 1.3; 95% CI, -7.1 to 9.6; P = .76) effects. Improvements in I-HOPE performance and satisfaction scores were greater for COMPASS participants than control participants at 12 months (between-group differences in changes for performance: 0.39; 95% CI, 0.01-0.77; P = .046; satisfaction: 0.52; 95% CI, 0.08-0.96; P = .02). The COMPASS participants had greater improvements for I-HOPE environmental barriers than the control participants (P = .003 for interaction), with the largest differences at 6 months (between-group differences in changes: -15.3; 95% CI -24.4 to -6.2).

Conclusions and Relevance

In this randomized clinical trial of stroke survivors, participants in both groups experienced improvements in community participation. COMPASS participants had greater improvements in self-rated performance and satisfaction with performing daily activities as well as a greater reduction in environmental barriers than control participants. COMPASS reduced environmental barriers and improved performance of daily activities for stroke survivors as they transitioned from inpatient rehabilitation to home.

"I just kept asking and asking and there was nothing": re-thinking community resources & supports for young adult stroke survivors

PURPOSE

Stroke is often regarded as a disease of the elderly. However, 10-15% of strokes occur in people aged 18 to 50, and rates continue to rise. Young stroke survivors face unique challenges due to their occupational, family and personal commitments, which current stroke rehabilitation services may not fully address. Our qualitative study aimed to identify gaps in patient care and resources for young stroke survivors. We used these findings to develop recommendations to inform clinical care, healthcare system design, and health policy.

METHODS

Using Interpretive Description, we conducted semi-structured interviews with 19 stroke survivors aged 18-55 living in British Columbia, Canada, to explore their experiences during stroke recovery and assess current gaps in support and resources. We applied broad-based coding and thematic analysis to the transcripts.

RESULTS

Key themes included: (1) the need for longitudinal medical follow-up and information provision, (2) the need for psychological/psychiatric care, (3) the need to adapt community supports and resources to young survivors, and (4) the need to centralize and integrate community stroke services and resources.

CONCLUSION

Young stroke survivors experience unique challenges and lack appropriate services and resources. Many of our findings may be representative of remediable gaps that persist nationally and internationally.

Community Participation Transition After Stroke (COMPASS) Randomized Controlled Trial: Effect on Adverse Health Events

OBJECTIVE

To compare adverse health events in intervention versus control group participants in the Community Participation Transition After Stroke trial to reduce barriers to independent living for community-dwelling stroke survivors.

DESIGN

Randomized controlled trial.

SETTING

Inpatient rehabilitation (IR) to home and community transition.

PARTICIPANTS

Stroke survivors aged ≥50 years being discharged from IR who had been independent in activities of daily living prestroke (N=183).

INTERVENTIONS

Participants randomized to intervention group (n=85) received home modifications and self-management training from an occupational therapist over 4 visits in the home. Participants randomized to control group (n=98) received the same number of visits consisting of stroke education.

MAIN OUTCOME MEASURES

Death, skilled nursing facility (SNF) admission, 30-day rehospitalization, and fall rates after discharge from IR.

RESULTS

Time-to-event analysis revealed that the intervention reduced SNF admission (cumulative survival, 87.8%; 95% confidence interval [CI], 78.6%-96.6%) and death (cumulative survival, 100%) compared with the control group (SNF cumulative survival, 78.9%; 95% CI, 70.4%-87.4%; P=.039; death cumulative survival, 87.3%; 95% CI, 79.9%-94.7%; P=.001). Thirty-day rehospitalization also appeared to be lower among intervention participants (cumulative survival, 95.1%; 95% CI, 90.5%-99.8%) than among control participants (cumulative survival, 86.3%; 95% CI, 79.4%-93.2%; P=.050) but was not statistically significant. Fall rates did not significantly differ between the intervention group (5.6 falls per 1000 participant-days; 95% CI, 4.7-6.5) and the control group (7.2 falls per 1000 participant-days; 95% CI, 6.2-8.3; incidence rate ratio, 0.78; 95% CI, 0.46-1.33; P=.361).

CONCLUSIONS

A home-based occupational therapist-led intervention that helps stroke survivors transition to home by reducing barriers in the home and improving self-management could decrease the risk of mortality and SNF admission after discharge from rehabilitation.

Perispinal Etanercept to improve STroke Outcomes (PESTO): Protocol for a multicenter, international, randomized placebo-controlled trial

RATIONALE

A large proportion of stroke survivors will have long-lasting, debilitating neurological impairments, yet few efficacious medical treatment options are available. Etanercept inhibits binding of tumor necrosis factor to its receptor and is used in the treatment of inflammatory conditions. Perispinal subcutaneous injection followed by a supine, head down position may bypass the blood brain barrier. In observational studies and one small randomized controlled trial the majority of patients showed improvement in multiple post stroke impairments.

AIM

Perispinal Etanercept to improve STroke Outcomes (PESTO) investigates whether perispinal subcutaneous injection of etanercept improves quality of life and is safe in patients with chronic, disabling, effects of stroke.

METHODS AND DESIGN

PESTO is a multicenter, international, randomized placebo-controlled trial. Adult participants with a history of stroke between 1 and 15 years before enrollment and a current modified Rankin scale between 2 and 5 who are otherwise eligible for etanercept are randomized 1:1 to single dose injection of etanercept or placebo.

STUDY OUTCOMES

The primary efficacy outcome is quality of life as measured using the Short Form 36 Health Inventory at day 28 after first injection. Safety outcomes include serious adverse events.

SAMPLE SIZE TARGET

A total of 168 participants assuming an improvement of the SF-36 in 11% of participants in the control arm and in 30% of participants in the intervention arm, 80% power and 5% alpha.

DISCUSSION

PESTO aims to provide level 1 evidence on the safety and efficacy of perispinal etanercept in patients with long-term disabling effects of stroke.

Delirium Mediated the Association Between a History of Falls and Short-Term Mortality Risk in Critically Ill Ischemic Stroke Patients

Patients with ischemic stroke have an increased propensity to fall, resulting in significant physical and psychological distress. This study examined the association between falls in the 3 months prior to intensive care unit (ICU) admission and mortality within 28 days among 2950 adult ICU patients diagnosed with ischemic stroke from 2008 to 2019, focusing on the potential mediating role of delirium. The primary outcomes were short-term mortality (28, 60, and 90 days) and the risk of delirium. Each patient was followed for at least 1 year. Delirium was primarily assessed using the Confusion Assessment Method for the ICU and by reviewing nursing notes. Group differences between patients with and without a history of falls were compared using the Wilcoxon rank-sum test or the chi-squared test. Cox proportional risk or logistic regression models were used to explore the association between fall history and outcomes, and causal mediation analysis was performed. Results showed that patients with a recent fall history had a significantly increased risk of 28-day (hazard ratio [HR]: 1.62, 95% confidence interval [CI]: 1.35-1.94), 60-day (HR: 1.67, 95% CI: 1.42-1.98), and 90-day mortality (HR: 1.66, 95% CI: 1.41-1.95), as well as an increased risk of delirium (odds ratio: 2.00, 95% CI: 1.66-2.42). Delirium significantly mediated the association between fall history and 28-day mortality (total effect: HR: 1.77, 95% CI: 1.45-2.16; natural indirect effect: HR: 1.12, 95% CI: 1.05-1.21; proportion mediated: 24.6%). These findings suggest that ischemic stroke patients with a recent fall have an increased risk of short-term mortality, partly mediated by delirium. Strategies aimed at preventing delirium may potentially improve prognosis in this patient population.

Folic acid for the primary prevention of stroke: a systematic review and meta-analysis

OBJECTIVES

Results from studies were inconsistent with regard to the effect of folic acid on the primary prevention of stroke. The aim of this study was to analyze the association between folic acid and the primary prevention of stroke using the data from observational studies and randomized controlled trials (RCTs).

METHODS

Eligible publications published until June 2024 were searched in the database of PubMed, Web of Science and Embase. This study included all observational studies and RCTs of folic acid with first stroke as the reporting endpoints. Relative risks (RRs) and 95% confidence intervals (CIs) were pooled in the random-effects model to assess the effect of folic acid on the primary prevention of stroke.

RESULTS

Results from 12 observational publications with 16 research, including 312,320 participants, were combined to explore the association between dietary folic acid intake and the primary prevention of stroke. The results showed that high dietary folic acid intake was associated with a 17% reduction in stroke incidence (RR:0.83; 95% CI: 0.73-0.94), and the effect of dietary folic acid was greater in areas without grain fortification (RR:0.80; 95% CI: 0.67-0.95). The pooled results from 12 RCTs, totaling 75,042 participants, indicated that folic acid supplementation was not associated with the stroke primary prevention (RR:0.92; 95% CI: 0.80-1.05), but folic acid supplementation was effective in areas without grain fortification (RR:0.78; 95% CI: 0.68-0.89).

CONCLUSION

Our meta-analysis demonstrated that dietary folic acid is effective in stroke primary prevention, and folic acid supplementation is effective in stroke primary prevention only in areas without grain fortification.

Experiences and preferences of people with stroke and caregivers, around supports provided at the transition from hospital to home: a qualitative descriptive study

BACKGROUND

Transitioning home from the structured hospital setting poses challenges for people with stroke (PWS) and their caregivers (CGs), as they navigate through complex uncertainties. There are gaps in our understanding of appropriate support interventions for managing the transition home. In this qualitative study, we explored the perspectives of PWS and their CGs regarding their support experiences and preferences during this period.

METHODS

Between November 2022 and March 2023, and within six months of hospital discharge, audio-recorded, semi-structured interviews were conducted with PWS and CGs. All interviews were transcribed, imported into NVivo software, and analysed using reflexive thematic analysis.

RESULTS

Sixteen interviews were conducted, nine with PWS and seven with CGs. Four themes relevant to their collective experiences and preferences were identified: (i) Need for tailored information-sharing, at the right time, and in the right setting; (ii) The importance of emotional support; (iii) Left in limbo, (iv) Inequity of access. Experiences depict issues such as insufficient information-sharing, communication gaps, and fragmented and inequitable care; while a multi-faceted approach is desired to ease anxiety and uncertainty, minimise delays, and optimise recovery and participation during transition.

CONCLUSIONS

Our findings highlight that regardless of the discharge route, and even with formal support systems in place, PWS and families encounter challenges during the transition period. The experiences of support at this transition and the preferences of PWS and CGs during this important period highlights the need for better care co-ordination, early and ongoing emotional support, and equitable access to tailored services and support. Experiences are likely to be improved by implementing a partnership approach with improved collaboration, including joint goal-setting, between PWS, CGs, healthcare professionals and support organisations.

Nanomaterial-Based Strategies for Attenuating T-Cell-Mediated Immunodepression in Stroke Patients: Advancing Research Perspectives

This review article discusses the potential of nanomaterials in targeted therapy and immunomodulation for stroke-induced immunosuppression. Although nanomaterials have been extensively studied in various biomedical applications, their specific use in studying and addressing immunosuppression after stroke remains limited. Stroke-induced neuroinflammation is characterized by T-cell-mediated immunodepression, which leads to increased morbidity and mortality. Key observations related to immunodepression after stroke, including lymphopenia, T-cell dysfunction, regulatory T-cell imbalance, and cytokine dysregulation, are discussed. Nanomaterials, such as liposomes, micelles, polymeric nanoparticles, and dendrimers, offer advantages in the precise delivery of drugs to T cells, enabling enhanced targeting and controlled release of immunomodulatory agents. These nanomaterials have the potential to modulate T-cell function, promote neuroregeneration, and restore immune responses, providing new avenues for stroke treatment. However, challenges related to biocompatibility, stability, scalability, and clinical translation need to be addressed. Future research efforts should focus on comprehensive studies to validate the efficacy and safety of nanomaterial-based interventions targeting T cells in stroke-induced immunosuppression. Collaborative interdisciplinary approaches are necessary to advance the field and translate these innovative strategies into clinical practice, ultimately improving stroke outcomes and patient care.

Secondary Prevention in Patients With Stroke Versus Myocardial Infarction: Analysis of 2 National Cohorts

BACKGROUND

The implementation of preventive therapies among patients with stroke remains inadequately explored, especially when compared with patients with myocardial infarction (MI), despite sharing similar vascular risk profiles. We tested the hypothesis that participants with a history of stroke have a worse cardiovascular prevention profile in comparison to participants with MI.

METHODS AND RESULTS

In cross-sectional analyses within the UK Biobank and All of Us Research Program, involving 14 760 (9193 strokes, 5567 MIs) and 7315 (2948 strokes, 4367 MIs) participants, respectively, we evaluated cardiovascular prevention profiles assessing low-density lipoprotein (<100 mg/dL), blood pressure (systolic, <140 mm Hg; and diastolic, <90 mm Hg), statin and antiplatelet use, and a cardiovascular prevention score that required meeting at least 3 of these criteria. The results revealed that, within the UK Biobank, patients with stroke had significantly lower odds of meeting all the preventive criteria compared with patients with MI: low-density lipoprotein control (odds ratio [OR], 0.73 [95% CI, 0.68-0.78]; P<0.001), blood pressure control (OR, 0.63 [95% CI, 0.59-0.68]; P<0.001), statin use (OR, 0.45 [95% CI, 0.42-0.48]; P<0.001), antiplatelet therapy use (OR, 0.30 [95% CI, 0.27-0.32]; P<0.001), and cardiovascular prevention score (OR, 0.42 [95% CI, 0.39-0.45]; P<0.001). Similar patterns were observed in the All of Us Research Program, with significant differences across all comparisons (P<0.05), and further analysis suggested that the odds of having a good cardiovascular prevention score were influenced by race and ethnicity as well as neighborhood deprivation levels (interaction P<0.05 in both cases).

CONCLUSIONS

In 2 independent national cohorts, patients with stroke showed poorer cardiovascular prevention profiles and lower adherence to guideline-directed therapies compared with patients with MI. These findings underscore the need to explore the reasons behind the underuse of secondary prevention in vulnerable stroke survivors.

The Effect of Respiratory Muscle Training on Swallowing Function in Patients With Stroke: A Systematic Review and Meta-Analysis

BACKGROUND

The improvement of swallowing function after stroke is a significant challenge faced by patients and health care professionals. However, the current evidence synthesis of the effects of respiratory muscle training (RMT) on swallowing function is limited.

OBJECTIVE

To assess the effectiveness of RMT on swallowing recovery in patients undergoing stroke.

METHODS

The CKNI, WanFang Data, PubMed, CINAHL, Web of Science, Embase, MEDLINE, and Cochrane Library databases were searched for studies evaluating RMT interventions' effect on swallowing outcomes. Risks of bias were evaluated using the approach recommended by the Cochrane Collaboration tool and a summary of findings table was generated using the GRADE approach. Outcomes were synthesized using a random-effects meta-analysis model.

RESULTS

RMT interventions reduced the risk of aspiration (SMD = 1.19; 95% CI, 0.53-1.84), the recovery process of water swallowing function (RR = 1.22; 95% CI, 1.05-1.42), and the activity of the swallowing muscles (SMD = 2.91; 95% CI, 2.22-3.61). However, there was no significant effect of RMT on the functional level of oral intake (SMD = 0.70; 95% CI, -0.03 to 1.42).

CONCLUSIONS

RMT can be regarded as an innovative, auxiliary means in the near future to better manage and improve swallowing function, given its improving effect on work outcomes in this review.

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.

The caregiver contribution to self-care of stroke inventory (CC-SCSI): evaluation of psychometric characteristics

BACKGROUND

The caregiver contribution to self-care plays an important role in improving the health outcomes of chronic patients, which needs urgent attention. However, it has been hindered by the lack of a tailored instrument that assesses the caregiver contribution to self-care of stroke.

OBJECTIVES

To test the psychometric characteristics of the caregiver contribution to self-care of stroke Inventory (CC-SCSI) in health care practice.

METHODS

Participants were recruited in Henan Province from March 2021 to October 2022, utilizing a multicenter stratified sampling approach. A 23-item self-report CC-SCSI with 3 separate scales measuring caregiver contribution to self-care maintenance of stroke, caregiver contribution to self-care monitoring of stroke and caregiver contribution to self-care management of stroke was tested for validity through discriminant validity, confirmatory factor analysis, concurrent validity and convergent validity. The reliability was tested by Cronbach's α coefficient and test-retest reliability. Qualitative data were analysed using thematic analysis. A STROBE checklist was used.

RESULTS

The three scales of the CC-SCSI exhibited good discriminant validity. Confirmatory factor analysis supported the three-factor structure of the Caregiver Contribution to Stroke Self-Care Maintenance and Management scales and the one-factor structure of the Caregiver Contribution to Stroke Self-Care Monitoring scale. The moderate correlation between the CC-SCSI and the Self-Care of Stroke Inventory indicated acceptable concurrent validity. The moderate correlation between the CC-SCSI and the Caregiver Contribution to Self-Care of Chronic Illness Inventory indicated acceptable convergent validity. Cronbach's αs for the Caregiver Contribution to Self-Care Maintenance, Self-Care Monitoring, and Self-Care Management scales ranged from 0.876 to 0.974. Test-retest reliability showed average ICC values ranging from 0.828 to 0.903 (P < 0.001).

CONCLUSIONS

The 23-item CC-SCSI presents good psychometric properties and could be used to explore the caregiver contribution to stroke self-care in health care practice and research.

Development and psychometric testing of the Self-Care of Stroke Inventory

PURPOSE

To develop and evaluate the psychometric properties of the Self-Care of Stroke Inventory (SCSI).

MATERIALS AND METHODS

A cross-sectional, instrument development and the psychometric testing study was conducted. A 23-item self-report Self-Care of Stroke Inventory with 3 separate scales was developed. This study involved three stages: (a) Initial items generation; (b) Content and face validation; (c) Psychometric properties evaluation. The SCSI was validated by content validity, construct validity, convergent validity, internal consistency, and test-retest reliability.

RESULTS

From the initial 80-item pool, 24 items of 3 scales in the SCSI were retained by the expert consultation and item analysis. The scale's content validity was 0.976, 0.966, and 0.973. The EFA showed the total variance explained by the 3 scales of the SCSI were 73.417%, 74.281%, and 80.207%, respectively. The models of the 3 scales identified by EFA were all confirmed by the CFA. The SCSI scale shows evidence of good convergent validity. Cronbach's αs were 0.830, 0.930, and 0.831. Test-retest reliability of the SCSI was excellent, with an intraclass correlation coefficient of 0.945, 0.907, and 0.837.

CONCLUSIONS

The final 23-item SCSI presents good psychometric properties and can be used to explore the self-care of stroke in community settings.IMPLICATIONS FOR REHABILITATIONThis study developed and validated the Self-Care of Stroke Inventory (SCSI).The SCSI contains the following 3 scales: the Self-care Maintenance of Stroke scale, the Self-care Monitoring of Stroke scale, and the Self-care Management of Stroke scaleThe 23-item SCSI demonstrated strong psychometric properties.The SCSI may be used to develop future programmes to promote self-care for stroke survivors and improve their rehabilitation outcomes.

Predicting the functional outcome of intensive inpatient rehabilitation after stroke: results from the RIPS Study

BACKGROUND

The complexity of stroke sequelae, the heterogeneity of outcome measures and rehabilitation pathways, and the lack of extensively validated prediction models represent a challenge in predicting stroke rehabilitation outcomes.

AIM

To prospectively investigate a multidimensional set of variables collected at admission to inpatient post-stroke rehabilitation as potential predictors of the functional level at discharge.

DESIGN

Multicentric prospective observational study.

SETTING

Patients were enrolled in four Intensive Rehabilitation Units (IRUs).

POPULATION

Patients were consecutively recruited in the period December 2019-December 2020 with the following inclusion criteria: aged 18+, with ischemic/haemorrhagic stroke, and undergoing inpatient rehabilitation within 30 days from stroke.

METHODS

This is a multicentric prospective observational study. The rehabilitation pathway was reproducible and evidence-based. The functional outcome was disability in activities of daily living, measured by the modified Barthel Index (mBI) at discharge. Potential multidimensional predictors, assessed at admission, included demographics, event description, clinical assessment, functional and cognitive profile, and psycho-social domains. The variables statistically associated with the outcome in the univariate analysis were fed into a multivariable model using multiple linear regression.

RESULTS

A total of 220 patients were included (median [IQR] age: 80 [15], 112 women, 175 ischemic). Median mBI was 26 (43) at admission and 62.5 (52) at discharge. In the multivariable analysis younger age, along with better functioning, fewer comorbidities, higher cognitive abilities, reduced stroke severity, and higher motor functions at admission, remained independently associated with higher discharge mBI. The final model allowed a reliable prediction of discharge functional outcome (adjusted R2=77.2%).

CONCLUSIONS

The model presented in this study, based on easily collectable, reliable admission variables, could help clinicians and researchers to predict the discharge scores of the global functional outcome for persons enrolled in an evidence-based inpatient stroke rehabilitation program.

CLINICAL REHABILITATION IMPACT

A reliable outcome prediction derived from standardized assessment measures and validated treatment protocols could guide clinicians in the management of patients in the subacute phase of stroke and help improve the planning of the rehabilitation individualized project.

Predictive Performance of Machine Learning-Based Models for Poststroke Clinical Outcomes in Comparison With Conventional Prognostic Scores: Multicenter, Hospital-Based Observational Study

BACKGROUND

Although machine learning is a promising tool for making prognoses, the performance of machine learning in predicting outcomes after stroke remains to be examined.

OBJECTIVE

This study aims to examine how much data-driven models with machine learning improve predictive performance for poststroke outcomes compared with conventional stroke prognostic scores and to elucidate how explanatory variables in machine learning-based models differ from the items of the stroke prognostic scores.

METHODS

We used data from 10,513 patients who were registered in a multicenter prospective stroke registry in Japan between 2007 and 2017. The outcomes were poor functional outcome (modified Rankin Scale score >2) and death at 3 months after stroke. Machine learning-based models were developed using all variables with regularization methods, random forests, or boosted trees. We selected 3 stroke prognostic scores, namely, ASTRAL (Acute Stroke Registry and Analysis of Lausanne), PLAN (preadmission comorbidities, level of consciousness, age, neurologic deficit), and iScore (Ischemic Stroke Predictive Risk Score) for comparison. Item-based regression models were developed using the items of these 3 scores. The model performance was assessed in terms of discrimination and calibration. To compare the predictive performance of the data-driven model with that of the item-based model, we performed internal validation after random splits of identical populations into 80% of patients as a training set and 20% of patients as a test set; the models were developed in the training set and were validated in the test set. We evaluated the contribution of each variable to the models and compared the predictors used in the machine learning-based models with the items of the stroke prognostic scores.

RESULTS

The mean age of the study patients was 73.0 (SD 12.5) years, and 59.1% (6209/10,513) of them were men. The area under the receiver operating characteristic curves and the area under the precision-recall curves for predicting poststroke outcomes were higher for machine learning-based models than for item-based models in identical populations after random splits. Machine learning-based models also performed better than item-based models in terms of the Brier score. Machine learning-based models used different explanatory variables, such as laboratory data, from the items of the conventional stroke prognostic scores. Including these data in the machine learning-based models as explanatory variables improved performance in predicting outcomes after stroke, especially poststroke death.

CONCLUSIONS

Machine learning-based models performed better in predicting poststroke outcomes than regression models using the items of conventional stroke prognostic scores, although they required additional variables, such as laboratory data, to attain improved performance. Further studies are warranted to validate the usefulness of machine learning in clinical settings.

A retrospective analysis of the social determinants of health affecting stroke outcomes in a small hospital situated in a health professional shortage area (HPSA)

Where someone lives is a major determinant of population health. In the United States, people who live in Health Professional Shortage Areas are considered medically underserved and have a higher propensity for conditions such as stroke, hypertension, and diabetes. Our goal was to better understand the diverse needs of patients presenting to the Crouse Hospital emergency department with stroke symptoms. Crouse Hospital is a small community hospital located in a shortage area serving both urban and rural populations in and around Syracuse, New York. Despite its small size, Crouse Hospital quickly became a major comprehensive stroke center in Central New York. With this study we assessed the social factors affecting the stroke patient population in the community and compared these characteristics between those living in served and underserved areas. Informed by the social determinants of health framework, we analyzed 1731 incidents of stroke that occurred between January 2019 and January 2021, and observed that the circumstances associated with stroke varied by service category and race, with White patients and those from served areas having better stroke outcomes compared to those residing in underserved areas and those that were not White. Our analyses help us to understand the underlying factors influencing the observed disparities and allow us to move forward by implementing informed community-based interventions to decrease stroke incidence and improve post-stroke care. Using our example other small hospitals can enact similar strategies to address the social determinants affecting their patients to improve stroke outcomes in their region.

The acceptance and attitudes towards using assistive technology for people with stroke in Jordan: caregivers' perspectives

The aim of this study is to evaluate the acceptance and attitudes toward assistive technology (AT) for people with stroke from their caregivers' perspectives in Jordan. Also, this study further validates the Unified Theory of Acceptance and Use of Technology (UTAUT) questionnaire. This is a cross-sectional study that includes a three-sections survey: the first section contains demographic data, the second section includes the Unified Theory of Acceptance and Use of Technology (UTAUT) questionnaire, and the third section consists of two optional open-ended questions. Among 123 caregivers of people with stroke over 18 years of age who participated in this study, 23% were male. The findings indicate a moderate to high acceptance of using AT for stroke survivors, confirm the validity and reliability of the UTAUT questionnaire, and clarify novel issues regarding AT based on the caregivers' perspectives.

Prediction of Discharge Destination After Inpatient Rehabilitation for Stroke Using Mobility and Self-Care Assessment in Section GG of the Inpatient Rehabilitation Facility - Patient Assessment Instrument

Objective

To determine the ability of Section GG of the Inpatient Rehabilitation Facility - Patient Assessment Inventory (Section GG)'s quantification of mobility and self-care to predict discharge destination for persons with stroke after inpatient rehabilitation.

Design

Retrospective, observational cohort study.

Setting

150-bed inpatient rehabilitation facility within a metropolitan health system.

Participants

Consecutive sample of adults and older adults with stroke admitted for inpatient rehabilitation from January 2020 to June 2021 (N=1051). Subjects were excluded for discharge to acute care or hospice or if they had COVID-19.

Intervention

None.

Main Outcome Measures

Section GG self-care and mobility scores used in reimbursement formulation by Centers for Medicare and Medicaid at admission to inpatient rehabilitation; age; sex; prior living situation; discharge setting. Logistic regression examined binary comparisons of discharge destinations. Receiver operating characteristic (ROC) curves determined cut-off admission Section GG scores for binary comparisons.

Results

Logistic regression demonstrated that presence of a caregiver in the home was consistently the strongest predictor (P<.001) and admission Section GG scores were significant secondary factors in determining the discharge destination. An admission Section GG cut-off score of 33.5 determined home with homecare vs skilled nursing facility and a cut-off of 36.5 determined discharge to home with outpatient care vs skilled nursing facility.

Conclusion

Clinicians responsible for discharge decisions for patients with stroke after inpatient rehabilitation might start by determining the presence of a caregiver in the home and then use Section GG cut-off scores to guide decisions about home (with or without homecare) vs SNF destinations. Such guidance is not advised for the home with outpatient services vs home with homecare decision; clinical judgment is needed to determine the best discharge plan because this ROC had a less robust area under the curve. Sex and race/ethnicity were not determining factors for binary choices of discharge destinations.

The dyadic self-care experience of stroke survivors and their caregivers: A qualitative descriptive study

BACKGROUND

Promoting self-care is the core response strategy of the global health system to the burden of stroke. Although self-care in stroke represents a dyadic phenomenon, the dyadic self-care experience of stroke survivors and their caregivers is often overlooked in clinical practice.

OBJECTIVES

The aim of this study was to explore the dyadic self-care experience of stroke survivors and their caregivers.

DESIGN

A descriptive qualitative design was used to conduct the study.

RESULTS

The Consolidated Criteria for Reporting Qualitative Research was used for study reporting. A total of 21 stroke survivor-caregiver dyads were recruited for this study between May 2022 and September 2022. Data were collected through semistructured interviews and analyzed using thematic analysis. In this study, four themes were identified: (1) poor relationship quality of the dyads, (2) dyadic incongruence in managing stroke, (3) a slow and tiring dyadic self-care process and (4) happy cooperation in coping with dyadic self-care.

DISCUSSION AND CONCLUSION

Healthcare professionals should give greater consideration to the contradictions and disparities that may arise between stroke survivors and caregivers during the self-care process. It is crucial for them to provide personalized and tailored support and interventions that can assist these individuals in achieving a more optimal balance in their dyadic self-care.

PATIENT/PUBLIC CONTRIBUTION

Patients were involved in the formulation of interview questions for this study. No members of the public were involved in this study.

Integrative Approaches in Acute Ischemic Stroke: From Symptom Recognition to Future Innovations

Among the high prevalence of cerebrovascular diseases nowadays, acute ischemic stroke stands out, representing a significant worldwide health issue with important socio-economic implications. Prompt diagnosis and intervention are important milestones for the management of this multifaceted pathology, making understanding the various stroke-onset symptoms crucial. A key role in acute ischemic stroke management is emphasizing the essential role of a multi-disciplinary team, therefore, increasing the efficiency of recognition and treatment. Neuroimaging and neuroradiology have evolved dramatically over the years, with multiple approaches that provide a higher understanding of the morphological aspects as well as timely recognition of cerebral artery occlusions for effective therapy planning. Regarding the treatment matter, the pharmacological approach, particularly fibrinolytic therapy, has its merits and challenges. Endovascular thrombectomy, a game-changer in stroke management, has witnessed significant advances, with technologies like stent retrievers and aspiration catheters playing pivotal roles. For select patients, combining pharmacological and endovascular strategies offers evidence-backed benefits. The aim of our comprehensive study on acute ischemic stroke is to efficiently compare the current therapies, recognize novel possibilities from the literature, and describe the state of the art in the interdisciplinary approach to acute ischemic stroke. As we aspire for holistic patient management, the emphasis is not just on medical intervention but also on physical therapy, mental health, and community engagement. The future holds promising innovations, with artificial intelligence poised to reshape stroke diagnostics and treatments. Bridging the gap between groundbreaking research and clinical practice remains a challenge, urging continuous collaboration and research.

Effectiveness of a smartphone-enabled dyadic self-care programme (SDSCP) for stroke survivors and caregivers: study protocol for a randomised controlled trial

INTRODUCTION

The promotion of self-care has begun to serve as a central response strategy to the rising burden of stroke. In fact, stroke self-care can be recognised to be a dyad phenomenon having an effect on the health of stroke survivors and their caregivers. While studies have confirmed the effectiveness of smartphone-based interventions in improving self-care among stroke survivors, there remains a lack of evidence specifically regarding dyadic self-care interventions for both patients and caregivers.

AIM

The present single-blinded, two-arm, randomised controlled trial aims to verify the effectiveness of a smartphone-enabled dyadic self-care programme (SDSCP) for stroke survivors and their caregivers.

METHODS AND ANALYSIS

The estimated sample size is 152 stroke survivor-caregiver dyads. The participants will be randomly classified (1:1) into either a control (N=76) or an experimental group (N=76) through block randomisation. The participants classified into the experimental group will be provided with SDSCP, and during the initial home visit, the research team members will provide instructions to all patients and caregivers on how to download and use the smartphone application. While the participants in the control group will be given the existing stroke standard care. The main outcome measures of stroke survivors will consist of the Self-Care of Stroke Inventory and a short version of the Stroke Specific Quality of Life Scale. The outcome measures of stroke caregivers will primarily cover the Caregiver Contribution to Self-Care of Stroke Inventory and Zarit burden interview. The data of this study will be collected at three time points, including baseline, 1 month and 6 months from the baseline.

ETHICS AND DISSEMINATION

This study has been approved by the Ethics Committee of Zhengzhou University (ZZUIRB 2021-115) in January 2021. The results achieved in this study will facilitate the clinical practice to improve self-care of stroke survivors and promote dyadic health outcomes for stroke patients and caregivers.

TRIAL REGISTRATION NUMBER

The study was registered with the Chinese Clinical Trial Registry and the registration number is ChiCTR2100053591.

Effects of videoconferencing intervention on stroke survivors: A systematic review and meta-analysis of randomised controlled studies

BACKGROUND

Videoconferencing has been proposed as an innovative telerehabilitation approach for stroke survivors, demand for which is growing.

AIM

To evaluate the efficacy of a videoconferencing intervention for stroke survivors.

DESIGN

Systematic review and meta-analysis.

METHODS

We conducted a systematic review of the literature in the databases Academic Search Complete, CINAHL, Cochrane Library, EMBASE, MEDLINE, PubMed, Ovid (and its companion UpToDate), and Web of Science published from January 1, 2002, to May 27, 2021. The methodologic quality of the included studies was evaluated using version 2 of the Cochrane risk-of-bias tool. A meta-analysis using a random-effects model calculated the pooled standardised mean difference (SMD) for using a videoconferencing intervention with stroke survivors and for the ability of survivors to perform activities of daily living (ADLs) and to maintain balance. The Stata software application (version 16.0: StataCorp LP) was used for the statistical analysis.

RESULTS

Nine studies with 603 participants were included in the analysis. Videoconferencing interventions were observed to be effective in improving the ability of stroke survivors to carry out their ADLs (SMD: 0.57; 95% confidence interval [CI]: 0.13 to 1.01) and to recover their balance (SMD: 1.96; 95% CI: 1.27 to 2.66).

CONCLUSIONS

Stroke survivors were able effectively to improve their ADL and balancing abilities. Further studies could consider the frequency, duration, and standard protocol for videoconferencing interventions.

RELEVANCE TO CLINICAL PRACTICE

This study could change the approach to patient support in future clinical practice and might constitute an alternative for improving care for stroke survivors in their homes or in long-term care facilities.

Supportive care needs of patients who had a stroke: a scoping review protocol

INTRODUCTION

Incidences of stroke are on the rise and approximately 80 million stroke survivors worldwide live with disabilities. Supportive care needs of stroke survivors are not adequately defined, and the assessment tools to help care service providers identify these needs are unclear. The overall aim of this scoping review will be to map the supportive care needs of stroke survivors against the Supportive Care Needs Framework.

METHODS AND ANALYSIS

This scoping review will be conducted following Arksey and O'Malley's methodological framework and Joanna Briggs Institute (JBI) updated methodological guidance for scoping review. This review will mainly use Arksey and O'Malley's methodological framework as the basic framework. The review will also follow JBI's updated methodological guidance for scoping reviews to optimise the review. For the search strategy, the three-step method recommended by the JBI will be used in the study. The review will be reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for Scoping Reviews. Six English databases, including PubMed, CINAHL, Web of Science, Embase, Cochrane Library and PsycInfo, and four Chinese databases, including CNKI, Wanfang, VIP and China Biomedical Literature Database will be systematically searched from inception to the present. Studies published in English and Chinese will be included.

ETHICS AND DISSEMINATION

Ethical approval is not required as this scoping review does not involve human participants. The findings shall be disseminated at scientific conferences and published in a peer-reviewed journal.

Association between malnutrition and stroke-associated pneumonia in patients with ischemic stroke

BACKGROUND

Malnutrition is associated with a high risk of mortality in adults with ischemic stroke (IS). This study aimed to investigate the relationship between malnutrition and the risk of stroke-associated pneumonia (SAP) as only a few studies examined the relationship between malnutrition and the risk of SAP in IS.

METHODS

Patients were included from emergency departments of five tertiary hospitals in the REtrospective Multicenter study for Ischemic Stroke Evaluation (REMISE) study from January 2020 to December 2020. Malnutrition was defined according to the Controlling Nutritional Status (CONUT), Geriatric Nutritional Risk Index (GNRI), and Prognostic Nutritional Index (PNI) systems. Multivariable logistic regression analysis was used to explore the association between malnutrition and risk of SAP.

RESULTS

We enrolled 915 patients with IS, 193 (14.75%), 495 (54.1%), and 148 (16.2%) of whom were malnourished according to the PNI, CONUT, and GNRI scores, respectively. SAP occurred in 294 (32.1%) patients. After adjusting for confounding influencing factors in the logistic regression analysis, malnutrition (moderate and severe risk vs. absent malnutrition) was independently associated with an increased risk of SAP based on the PNI (odds ratio [OR], 5.038; 95% confidence interval [CI] 2.435-10.421, P < 0.001), CONUT (OR, 6.941; 95% CI 3.034-15.878, P < 0.001), and GNRI (OR, 2.007; 95% CI 1.186-3.119, P = 0.005) scores. Furthermore, adding malnutrition assessment indices to the A2DS2 score significantly improved the ability to predict SAP by analysis of receiver operating characteristic curves and net reclassification improvement.

CONCLUSION

Malnutrition was notably prevalent in patients with IS and independently associated with an increased risk of SAP. Further studies are required to identify the effect of interventions on malnutrition to reduce the risk of SAP.

Interventions for Behaviour Change and Self-Management of Risk in Stroke Secondary Prevention: An Overview of Reviews

INTRODUCTION

Optimised secondary prevention strategies that include lifestyle change are recommended after stroke. While multiple systematic reviews (SRs) address behaviour change interventions, intervention definitions, and associated outcomes differ between reviews. This overview of reviews addresses the pressing need to synthesise high-level evidence for lifestyle-based behavioural and/or self-management interventions to reduce risk in stroke secondary prevention in a structured, consistent way.

METHODS

Grading of Recommendations Assessment, Development, and Evaluation (GRADE) criteria were applied to meta-analyses, demonstrating statistically significant effect sizes to establish the certainty of existing evidence. Electronic databases MEDLINE, Embase, Epistemonikos, and the Cochrane Library of Systematic Reviews were systematically searched, current to March 2023.

RESULTS

Fifteen SRs were identified following screening, with moderate overlap of primary studies demonstrated (5.84% degree of corrected covered area). Interventions identified could be broadly categorised as multimodal; behavioural change; self-management; psychological talk therapies, albeit with overlap between some theoretical domains. Seventy-two meta-analyses addressing twenty-one preventive outcomes of interest were reported. Best-evidence synthesis identifies that for primary outcomes of mortality and future cardiovascular events post-stroke, moderate certainty GRADE evidence supports multimodal interventions to reduce cardiac events, with no available evidence for outcomes of mortality (all-cause or cardiovascular) or recurrent stroke events. For secondary outcomes addressing risk-reducing behaviours, best-evidence synthesis identifies moderate certainty GRADE evidence for multimodal lifestyle-based interventions to increase physical activity participation, and low certainty GRADE evidence for behavioural change interventions to improve healthy eating post-stroke. Similarly, low certainty GRADE evidence supports self-management interventions to improve preventive medication adherence. For mood self-management post-stroke, moderate GRADE evidence supports psychological therapies for remission and/or reduction of depression and low/very low certainty GRADE evidence for reduction of psychological distress and anxiety. Best-evidence for outcomes addressing proxy physiological measures identified low GRADE evidence supporting multimodal interventions to improve blood pressure, waist circumference, and LDL cholesterol.

CONCLUSION

Effective strategies to redress risk-related health behaviours are required in stroke survivors to complement current pharmacological secondary prevention. Inclusion of multimodal interventions and psychological talk therapies in evidence-based stroke secondary prevention programmes is warranted given the moderate GRADE of evidence that supports their role in risk reduction. Given the overlap in primary studies across reviews, often with overlapping theoretical domains between broad intervention categories, further research is required to identify optimal intervention behavioural change theories and techniques employed in behavioural/self-management interventions.

Stroke burden and attributable risk factors in China, 1990-2019

Background and purpose

Understanding the temporal trends of stroke burden and its attributable risk factors are essential for targeted prevention strategies. We aimed to describe the temporal trends and attributable risk factors of stroke in China.

Methods

Data on the stroke burden [incidence, prevalence, mortality, and disability-adjusted life years (DALYs)] and the population-attributable fraction for stroke risk factors from 1990 to 2019 were obtained from the Global Burden of Disease Study 2019 (GBD 2019). We analyzed trends in the burden of stroke and its attributable risk factors from 1990 to 2019, and the characteristics of stroke-attributable risk factors by sex, age group, and stroke subtype.

Results

From 1990 to 2019, the age-standardized incidence, mortality, and DALY rates for total stroke decreased by 9.3% (3.3, 15.5), 39.8% (28.6, 50.7), and 41.6% (30.7, 50.9) respectively. The corresponding indicators all decreased for intracerebral hemorrhage and subarachnoid hemorrhage. The age-standardized incidence rate of ischemic stroke increased by 39.5% (33.5 to 46.2) for male patients and by 31.4% (24.7 to 37.7) for female patients, and the age-standardized mortality and DALY rates remained almost unchanged. The three leading stroke risk factors were high systolic blood pressure, ambient particulate matter pollution, and smoking. High systolic blood pressure has remained the leading risk factor since 1990. The attributable risk of ambient particulate matter pollution shows a clear upward trend. Smoking and alcohol consumption were important risk factors for men.

Conclusion

This study reinforced the findings of an increased stroke burden in China. Precise stroke prevention strategies are needed to reduce the disease burden of stroke.

Life-space mobility and post-hospitalization outcomes among older Mexican American Medicare beneficiaries

BACKGROUND

Older adults with limited mobility are at an increased risk of adverse health outcomes, an outcome inadequately investigated in older Mexican Americans. We explored whether pre-admission life-space mobility predicts post-hospitalization outcomes among hospitalized Mexican American Medicare beneficiaries.

METHODS

Life-space mobility, using the Life-Space Assessment (LSA), was analyzed using quartiles and 5-point intervals. Using the Hispanic Established Populations for the Epidemiologic Study of the Elderly (HEPESE) Waves 7 and 8 data linked to Medicare claims data, 426 older Mexican Americans with at least 2 months of Medicare coverage who were hospitalized within 2 years of completing the LSA were included. Logistic and Cox Proportional regression analyses estimated the association of pre-admission LSA with post-hospitalization outcomes.

RESULTS

Prior to hospitalization, 85.4% reported limited life-space mobility. Most patients (n = 322, 75.6%) were hospitalized for medical reasons. About 65% were discharged to the community. Pre-admission LSA scores were not associated with community discharge (Odds Ratio [OR] = 1.02, 0.95-1.10). Higher pre-admission LSA scores were associated with 30-day readmission (OR = 1.11, 1.01-1.22). Patients in the highest pre-admission LSA quartile (i.e., greatest life-space mobility) were less likely to die within 2 years after hospital discharge (OR = 0.61, 0.39-0.97) compared to those with lower pre-admission LSA scores.

CONCLUSIONS

Among older Mexican American Medicare beneficiaries, greater pre-admission LSA scores were associated with an increased risk of 30-day readmission and a decreased risk of mortality within 2 years following hospitalization. Future work should further investigate the relationship between LSA and post-hospitalization outcomes in a larger sample of Mexican American older adults.

The Rationalisation of Intra-Operative Imaging During Cardiac Surgery: A Systematic Review

INTRODUCTION

One critical complication of cardiac surgery is cerebrovascular accidents (CVAs). Ascending aorta atherosclerosis poses a significant risk of embolisation to distal vessels and to cerebral arteries. Epi-aortic ultrasonography (EUS) is thought to offer a safe, high-quality accurate visualisation of the diseased aorta to guide the surgeon on the best surgical approach to the planned procedure and potentially improve neurological outcomes post-cardiac surgery.

METHOD

The authors conducted a comprehensive search of PubMed, Scopus and Embase. Studies that reported on epi-aortic ultrasound use in cardiac surgery were included. Major exclusion criteria were: (1) abstracts, conference presentations, editorials, literature reviews; (2) case series with <5 participants; (3) epi-aortic ultrasound in trauma or other surgeries.

RESULTS

A total of 59 studies and 48,255 patients were included in this review. Out of the studies that reported patient co-morbidities prior to cardiac surgery, 31.6% had diabetes, 59.5% had hyperlipidaemia and 66.1% had a diagnosis of hypertension. Of those that reported significant ascending aorta atherosclerosis found on EUS, this ranged from 8.3% of patients to 95.2% with a mean percentage of 37.8%. Hospital mortality ranged from 7% to 13%; four studies reported zero deaths. Long-term mortality and stroke rate varied significantly with hospital duration.

CONCLUSION

Current data have shown EUS to have superiority over manual palpation and transoesophageal echocardiography in the prevention of CVAs following cardiac surgery. Yet, EUS has not been implemented as a routine standard of care. Extensive adoption of EUS in clinical practice is warranted to aid large, randomised trials before making prospective conclusions on the efficacy of this screening method.

Dietary calcium intake and the risk of stroke: Meta-analysis of cohort studies

BACKGROUND AND AIMS

Prospective cohorts are inconsistent regarding the association between dietary calcium intake and the risk of stroke. The aim was to perform a meta-analysis to determine whether an association exists between them in cohort studies.

METHODS AND RESULTS

Relevant studies were identified by searching PubMed, EMBASE and Web of Science databases that published before December 2022. Prospective cohort studies that provided relative risk (RR) estimates with 95% confidence intervals (CIs) for the association were included. Study-specific risk estimates were combined by using a random effects model. Eighteen prospective studies, including 19,557 stroke cases among 882,181 participants, were pooled in the meta-analysis. We observed a nonlinear association between calcium intake and risk of stroke (P_nonlinearity < 0.003). Compared with the lowest value of zero assumed as the reference, the RRs (95% CI) of stroke across levels of calcium intake were 0.95 (0.92, 0.98) for 200 mg/day, 0.94 (0.90, 0.98) for 300 mg/day, 0.95 (0.90, 0.99) for 500 mg/day, 0.98 (0.93, 1.03) for 700 mg/day, and 1.04 (0.97, 1.11) for 1000 mg/day. The stratified analyses by geographic region showed nonlinear associations and indicated that the protective effect was observed in Asian countries (P_nonlinearity = 0.001) but not in non-Asian regions (P_nonlinearity = 0.047).

CONCLUSION

This meta-analysis suggests that dietary calcium intake might play an effective role in the prevention of stroke, especially in Asian countries. Future research among Asia population should attempt to establish whether this association is causal.

National trends in the outcomes of subarachnoid haemorrhage and the prognostic influence of stroke centre capability in Japan: retrospective cohort study

OBJECTIVES

To examine the national, 6-year trends in in-hospital clinical outcomes of patients with subarachnoid haemorrhage (SAH) who underwent clipping or coiling and the prognostic influence of temporal trends in the Comprehensive Stroke Center (CSC) capabilities on patient outcomes in Japan.

DESIGN

Retrospective study.

SETTING

Six hundred and thirty-one primary care institutions in Japan.

PARTICIPANTS

Forty-five thousand and eleven patients with SAH who were urgently hospitalised, identified using the J-ASPECT Diagnosis Procedure Combination database.

PRIMARY AND SECONDARY OUTCOME MEASURES

Annual number of patients with SAH who remained untreated, or who received clipping or coiling, in-hospital mortality and poor functional outcomes (modified Rankin Scale: 3-6) at discharge. Each CSC was assessed using a validated scoring system (CSC score: 1-25 points).

RESULTS

In the overall cohort, in-hospital mortality decreased (year for trend, OR (95% CI): 0.97 (0.96 to 0.99)), while the proportion of poor functional outcomes remained unchanged (1.00 (0.98 to 1.02)). The proportion of patients who underwent clipping gradually decreased from 46.6% to 38.5%, while that of those who received coiling and those left untreated gradually increased from 16.9% to 22.6% and 35.4% to 38%, respectively. In-hospital mortality of coiled (0.94 (0.89 to 0.98)) and untreated (0.93 (0.90 to 0.96)) patients decreased, whereas that of clipped patients remained stable. CSC score improvement was associated with increased use of coiling (per 1-point increase, 1.14 (1.08 to 1.20)) but not with short-term patient outcomes regardless of treatment modality.

CONCLUSIONS

The 6-year trends indicated lower in-hospital mortality for patients with SAH (attributable to better outcomes), increased use of coiling and multidisciplinary care for untreated patients. Further increasing CSC capabilities may improve overall outcomes, mainly by increasing the use of coiling. Additional studies are necessary to determine the effect of confounders such as aneurysm complexity on outcomes of clipped patients in the modern endovascular era.

A Comparison of Acute Ischemic Stroke Patients Discharged to Inpatient Rehabilitation vs a Skilled Nursing Facility: The Paul Coverdell National Acute Stroke Program

OBJECTIVE

To compare the sociodemographic, clinical, and hospital related factors associated with discharge of acute ischemic stroke (AIS) survivors to inpatient rehabilitation (IRF) and skilled nursing facility (SNF) rehabilitation services.

DESIGN

Retrospective descriptive study from the Paul Coverdell National Acute Stroke Program (PCNASP) participating hospitals during 2016 to 2019.

SETTING

9 Participating states from PCNASP in United States.

PARTICIPANTS

130,988 patients with AIS from 569 hospitals (N=337,857).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE

Discharge to IRF and SNF.

RESULTS

Patients discharged to a SNF had longer length of hospital stay, more comorbidities, and higher modified Rankin scores compared with patients discharged to an IRF. Nine characteristics were associated with being less likely to be discharged to an IRF than an SNF: older age (85+ years old, adjusted odds ratio [AOR]=0.20 [confidence interval [CI]=0.18-0.21]), identifying as non-Hispanic Black (AOR=0.85 [CI=0.81-0.89]), identifying as Hispanic (AOR=0.80 [CI=0.74-0.87]), having Medicaid or Medicare (AOR=0.73 [CI=0.70-0.77]), being able to ambulate with assistance from another person (AOR=0.93 [CI=0.89-0.97]), being unable to ambulate (AOR=0.73 [CI=0.62-0.87]) and having comorbidities, prior stroke (AOR=0.69 [CI=0.66-0.73]), diabetes (AOR=0.85 [CI=0.82-0.88]), and myocardial infraction or coronary artery disease (AOR=0.94 [CI=0.90-0.97]). Four characteristics were associated with being more likely to be discharged to an IRF than an SNF: being a man (AOR=1.20 [CI=1.16-1.24]), and having a slight disability (Rankin Score 2) (AOR=1.41 [CI=1.29-1.54]), being at larger hospitals (200-399 beds: AOR=1.31 [CI=1.23-1.40]; 400+ beds: AOR=1.29 [CI=1.20-1.38]), and being at a hospital with stroke unit (AOR=1.12 [CI=1.07-1.17]).

CONCLUSION

This study found differences in demographic, clinical, and hospital characteristics of AIS patients discharged for rehabilitation to an IRF vs SNF. The characteristics of patients receiving rehabilitation services may be helpful for researchers and hospitals making policies related to stroke discharge and practices that optimize patient outcomes. Populations experiencing inequities in access to rehabilitation services should be identified, and those who qualify for rehabilitation in IRF should receive this care in preference to rehabilitation in SNF.

Inequities in Telemedicine Use Among Patients With Stroke and Cerebrovascular Diseases

Background and Objectives

In response to the COVID-19 pandemic, outpatient stroke care delivery was rapidly transformed to outpatient evaluation through video (VTM) and telephone (TPH) telemedicine (TM) visits around the world. We sought to evaluate the sociodemographic differences in outpatient TM use among stroke patients.

Methods

We conducted a retrospective chart review of outpatients evaluated at 3 tertiary stroke centers in the early period of the pandemic, 3/16/2020 through 7/31/2020. We compared the use of TM by patient characteristics including age, sex, race/ethnicity, insurance status, stroke type, patient type, and site. The association between TM use and patient characteristics was measured using the relative risk (RR) from a modified Poisson regression, and site-specific effects were controlled using a multilevel analysis.

Results

A total of 2,024 visits were included from UTHealth (n = 878), MedStar Health (n = 269), and Columbia (n = 877). The median age was 64 [IQR 52–74] years, and 53% were female. Approximately half of the patients had private insurance, 36% had Medicare, and 15% had Medicaid. Two-thirds of the visits were established patients. TM accounted for 90% of total visits, and the use of TM over office visits was primarily associated with site, not patient characteristics. TM utilization was associated with Asian and other/unknown race. Among TM users, older age, Black race, Hispanic ethnicity, and Medicaid insurance were associated with lower VTM use. Black (aRR 0.88, 95% CI 0.86–0.91,p< 0.001) and Hispanic patients (aRR 0.92, 95% CI 0.87–0.98,p= 0.005) had approximately 10% lower VTM use, while Asian patients (aRR 0.98, 95% CI 0.89–1.07,p= 0.59) had similar VTM use compared with White patients. Patients with Medicaid were less likely to use VTM compared with those with private insurance (aRR 0.86, 95% CI 0.81–0.91,p< 0.001).

Discussion

In our diverse cohort across 3 centers, we found differences in TM visit type by race and insurance early during the COVID-19 pandemic. These findings suggest disparities in VTM access across different stroke populations. As VTM remains an integral part of outpatient neurology practice, steps to ensure equitable access are essential.
