Correlation of Quality Metrics of Acute Stroke Care with Clinical Outcomes in an Indian Tertiary-care University Hospital: A Prospective Evidence-based Study

Aim

To characterize the impact of adherence to quality metrics of stroke care on the clinical outcomes of ischemic stroke (IS) and intracerebral hemorrhage (ICH) admissions.

Methods

Consecutive patients with acute stroke were prospectively followed up for their demographic and clinical characteristics, acute stroke management, and associated clinical outcomes at discharge. Stroke quality metrics [adopted from the American Heart Association (AHA)/American Stroke Association's Get with The Guidelines (GWTG)] with a specific interest in an association between acute reperfusion therapies and functional recovery in stroke patients are analyzed and presented. A composite measure of care was considered "0 (non-adherence) to 1 (adherence)." An all-or-none measure of care was calculated to check whether eligible patients received all the quality-of-care interventions. Multivariate Cox regression models were used to study an association between optimal adherence and clinical outcomes.

Results

During the study period, of the total 256 stroke admissions, 200 (78.1%) patients had IS, and the remaining 56 (21.9%) patients had ICH. The median [interquartile range (IQR)] age of total stroke admissions was 57 (36-78) years. Male preponderance was observed (IS: 80% and ICH: 67.9%). The conformity of performance metrics in IS patients was from 69.1% [95% confidence interval (CI), 68.5-69.6] for the use of deep vein thrombosis prophylaxis (DVTp) to 97.8% (95% CI, 96.2-98.6) for the use of statins. In ICH patients, it ranged from 61.7% (95% CI, 60.4-62.5) for the use of DVTp to 89.9% (95% CI, 88.6-89.7) for stroke rehabilitation. The unadjusted odds ratio (OR) of mortality (in-hospital plus the 28th-day postdischarge) was higher in ICH patients vs IS patients (4.42, p = 0.005). Optimal adherence with intravenous recombinant tissue plasminogen activator (IV-rtPA) therapy [hazards ratio (HR) = 0.23], in-hospital acute measures [IS (HR = 0.41) and ICH (HR = 0.63)], and discharge measures [IS (HR = 0.35) and ICH (HR = 0.45)] were associated with reduced hazards of the 28th-day mortality in both cohorts. Compared to ICH, IS patients had significantly improved neurofunctional recovery [modified Rankin score (mRS) ≤ 2, p < 0.01].

Conclusion

Adherence to quality metrics and performance measures was associated with low mortality and favorable clinical outcomes. Also, DVTp as an in-hospital (acute) measure of stroke care needs attention in both cerebrovascular events.

Standardized tools for assessing balance and mobility in stroke clinical practice guidelines worldwide: A scoping review

Background

Use of standardized tools to assess balance and mobility limitations is a recommended practice in stroke rehabilitation. The extent to which clinical practice guidelines (CPGs) for stroke rehabilitation recommend specific tools and provide resources to support their implementation is unknown.

Purpose

To identify and describe standardized, performance-based tools for assessing balance and/or mobility and describe postural control components challenged, the approach used to select tools, and resources provided for clinical implementation, in CPGs for stroke.

Methods

A scoping review was conducted. We included CPGs with recommendations on the delivery of stroke rehabilitation to address balance and mobility limitations. We searched seven electronic databases and grey literature. Pairs of reviewers reviewed abstracts and full texts in duplicate. We abstracted data about CPGs, standardized assessment tools, the approach for tool selection, and resources. Experts identified postural control components challenged by each tool.

Results

Of the 19 CPGs included in the review, 7 (37%) and 12 (63%) were from middle- and high-income countries, respectively. Ten CPGs (53%) recommended or suggested 27 unique tools. Across 10 CPGs, the most commonly cited tools were the Berg Balance Scale (BBS) (90%), 6-Minute Walk Test (6MWT) (80%), Timed Up and Go Test (80%) and 10-Meter Walk Test (70%). The tool most frequently cited in middle- and high-income countries was the BBS (3/3 CPGs), and 6MWT (7/7 CPGs), respectively. Across 27 tools, the three components of postural control most frequently challenged were underlying motor systems (100%), anticipatory postural control (96%), and dynamic stability (85%). Five CPGs provided information in varying detail on how tools were selected; only 1 CPG provided a level of recommendation. Seven CPGs provided resources to support clinical implementation; one CPG from a middle-income country included a resource available in a CPG from a high-income country.

Conclusion

CPGs for stroke rehabilitation do not consistently provide recommendations for standardized tools to assess balance and mobility or resources to facilitate clinical application. Reporting of processes for tool selection and recommendation is inadequate. Review findings can be used to inform global efforts to develop and translate recommendations and resources for using standardized tools to assess balance and mobility post-stroke.

Quality of the Indian clinical practice guidelines for the management of cardiovascular conditions

To assess the quality of Indian clinical practice guidelines (CPG)s for the management of cardiovascular conditions, MEDLINE, Embase, Google Scholar and websites of relevant medical associations and government organisations were searched, from inception until August 2020, to identify Indian CPGs for the management of cardiovascular disease (CVD) conditions, produced in or between 2010 and 2019. Excluded were CPGs that were not specific to India, focused on alternative systems of medicine, of non-CVD conditions (even if they included a component of CVD), and those related to the electronic devices, cardiac biomarkers, or diagnostic procedures. Quality of the each included CPG was assessed using the AGREE II tool by four reviewers in duplicate, independently. Each AGREE II domain score and overall quality score was considered low (≤40%), moderate (40.1%-59.9%), and high (≥60%). Of the 23 CPGs included, six (26%) were reported to be adapted from other CPGs. Fourteen (61%) CPGs were produced by medical associations, six (26%) by individual authors and three (13%) by government agencies. Based on the AGREE II overall quality score, two (9%) CPGs were of high quality, four (17%) and seventeen (74%) CPGs were of moderate and low quality, respectively. Except for scope and purpose, and clarity of presentation all other domains were rated low. The quality of most Indian CPGs for managing CVD conditions assessed using the AGREE II tool was moderate-to-low. Combined efforts from different stakeholders are needed to develop, disseminate and implement high-quality CPGs while identifying and addressing barriers to their uptake to optimize patient care and improve outcomes.

Bilateral Lower Limb Training for Post-stroke Survivors: A Bibliometric Analysis

Stroke is one of the most disabling conditions affecting the middle-aged population all around the world. This study aims to explore the rehabilitation of stroke patients using bibliometric analysis, which includes statistical analysis of recent articles, books, and other kinds of publications, to assess scientific output and determine the significance of scientific investigations in terms of both quality and quantity. In this study, an analysis of global trends in research in bilateral lower limb training for training balance and walking for patients in the subacute stage post-stroke between 1988 and 2021 was done. All the articles were obtained from PubMed databases. CiteSpace software was used to analyze the relationship between publications and country, journals, institutions, authors, references, and the keywords used. A total of 160 publications were included in the analysis. There was a tremendous increase in the research of physiotherapy intervention in patients who had residual disability post-stroke with a publication rate of 7.1 articles per year of publications. The use of the sophisticated PubMed database to extract articles allowed for a thorough and powerful bibliometric analysis of stroke rehabilitation research published between 1988 and 2020. In general, the number of studies on bilateral training has increased in recent decades. This historical overview of rehabilitation for post-stroke survivors will serve as a valuable starting point for future study into possible collaborators, focus issues, and trends. This bibliometric analysis highlights the potential value of exercise therapy for stroke survivors in creating more effective hemiplegia rehabilitation programs. This research may encourage the use of strengthening in the therapeutic therapy of hemiplegia balance. The groundwork will be laid for future research on strengthening stroke to be organized and given top priority.

Endovascular thrombectomy and intravenous alteplase in patients with acute ischemic stroke due to large vessel occlusion: A clinical practice guideline

AIM

Whether or not use of intravenous alteplase in combination with endovascular thrombectomy (EVT) improves outcomes versus EVT alone, for acute stroke patients with large vessel occlusion presenting directly to a comprehensive stroke center, is uncertain.

METHODS

Six randomized trials exploring this issue were published, and we synthesized this evidence to inform a rapid guideline based on the Guidelines International Network principles and guided by the GRADE approach.

RESULTS

We enlisted an international panel that included 4 patient partners and 1 caregiver, individuals from 6 countries. The panel considered low certainty evidence that EVT alone, relative to EVT with intravenous alteplase, possibly results in a small decrease in the proportion of patients that achieve functional independence and possibly a small increase in mortality. Both effect estimates were downgraded twice due to very serious imprecision. The panel also considered moderate certainty evidence that EVT alone probably decreases symptomatic intracranial hemorrhage, versus EVT with alteplase, and combination therapy was more costly than EVT alone. As a result of the low certainty for improved recovery without impairment and mortality for combination therapy versus EVT alone, and moderate certainty for increased harm with combination therapy, the panel made a weak recommendation in favor of EVT alone for stroke patients eligible for both treatments, and initially presenting directly to a comprehensive stroke center that provides both treatments.

CONCLUSIONS

Consistent with this weak recommendation, optimal patient management will likely often include co-treatment with intravenous alteplase, depending on local circumstances and patient presentation.

Do clinical guidelines guide clinical practice in stroke rehabilitation? An international survey of health professionals

PURPOSE

To identify health professionals awareness of stroke rehabilitation guidelines, and factors perceived to influence guideline use internationally.

METHODS

Online survey study. Open-ended responses were thematically analysed, guided by the Consolidated Framework for Implementation Research.

RESULTS

Data from 833 respondents from 30 countries were included. Locally developed guidelines were available in 22 countries represented in the sample. Respondents from high-income countries were more aware of local guidelines compared with respondents from low- and middle-income countries.Local contextual factors such as management support and a culture of valuing evidence-based practice were reported to positively influence guideline use, whereas inadequate time and shortages of skilled staff inhibited the delivery of guideline-recommended care. Processes reported to improve guideline use included education, training, formation of workgroups, and audit-feedback cycles. Broader contextual factors included accountability (or lack thereof) of health professionals to deliver rehabilitation consistent with guideline recommendations.

CONCLUSION

While many health professionals were aware of clinical guidelines, they identified multiple barriers to their implementation. Efforts should be made to raise awareness of local guidelines in low- and middle-income countries. More attention should be paid to addressing local contextual factors to improve guideline use internationally, going beyond traditional strategies focused on individual health professionals.IMPLICATIONS FOR REHABILITATIONSystems are required so people and organisations are held accountable to deliver evidence-based care in stroke rehabilitation.Locally developed stroke rehabilitation guidelines should be promoted to boost awareness of these guidelines in low- and middle-income countries.In all regions, strategies to influence or adapt to the local setting, are required to optimise guideline use.

Implementation of a Physician-Based Stroke Unit in a Remote Hospital of North-East India-Tezpur Model

Objective  The study aims to determine the effects of implementing stroke unit (SU) care in a remote hospital in North-East India.

Materials and Methods  This before-and-after implementation study was performed at the Baptist Christian Mission Hospital, Tezpur, Assam between January 2015 and December 2017. Before the implementation of stroke unit care (pre-SU), we collected information on usual stroke care and 1-month outcome of 125 consecutive stroke admissions. Staff was then trained in the delivery of SU care for 1 month, and the same information was collected in a second (post-SU) cohort of 125 patients.

Statistical Analysis  Chi-square and Mann–Whitney U test were used to compare group differences. The loss to follow-up was imputed by using multiple imputations using the Markov Chain Monto Carlo method. The sensitivity analysis was also performed by using propensity score matching of the groups for baseline stroke severity (National Institute of Health Stroke Scale) using the nearest neighbor approach to control for confounding, and missing values were imputed by using multiple imputations. The adjusted odds ratio was calculated in univariate and multivariate regression analysis after adjusting for baseline variables. All the analysis was done by using SPSS, version 21.0., IBM Corp and R version 4.0.0., Armonk, New York, United States.

Results  The pre-SU and post-SU groups were age and gender matched. The post-SU group showed higher rates of swallow assessment (36.8 vs. 0%, p < 0.001), mobility assessment, and re-education (100 vs. 91.5%, p = 0.037). The post-SU group also showed reduced complications (28 vs. 45%, p = 0.006) and a shorter length of hospital stay (4 ± 2.16 vs. 5 ± 2.68 days, p = 0.026). The functional outcome (modified ranking scale) at 1-month showed no difference between the groups, good outcome in post-SU (39.6%) versus pre-SU (35.7%), p = 0.552.

Conclusion  The implementation of this physician-based SU care model in a remote hospital in India shows improvements in quality measures, complications, and possibly patient outcomes.

Secondary Prevention by Structured Semi-Interactive Stroke Prevention Package in India (SPRINT INDIA) study protocol

RATIONALE

Recurrent stroke, cardiovascular morbidity, and mortality are important causes of poor outcome in patients with index stroke. Despite the availability of best medical management recurrent stroke occur in up to 15-20% of patients with stroke in India. Education for stroke prevention could be a strategy to prevent recurrent strokes.

HYPOTHESIS

We hypothesize that a structured semi-interactive stroke prevention package can reduce the risk of recurrent strokes, acute coronary artery syndrome, and death in patients with sub-acute stroke at the end of one year.

DESIGN

Secondary Prevention by Structured Semi-Interactive Stroke Prevention Package in INDIA (SPRINT INDIA) is a multi-center stroke trial involving 25 centers under the Indian Stroke Clinical Trial Network. Patients with first ever sub-acute stroke within two days to three months of onset, age 18-85 years, mRS <5, showing recent stroke in imaging are included. Participants or caregivers able to read and complete tasks suggested in a stroke prevention workbook and have a cellular device for receiving short message service and watching videos. A total of 5830 stroke patients speaking 11 different languages are being randomized to intervention or control arm. Patients in the intervention arm are receiving a stroke prevention workbook, regular educational short messages, and videos. All patients in the control arm are receiving standard of care management.

SUMMARY

Structured semi-interactive stroke prevention package may reduce the risk of recurrent strokes, acute coronary artery syndrome, and death in patients with sub-acute stroke.
