Effects of Social Determinants of Health on Acute Stroke Care Among Patients With Acute Ischemic Stroke: A Retrospective Cohort Study.

Social determinants of health (SDOH) are important contributors to poor stroke-related outcomes. While some have suggested that this association is driven by the increased incidence of stroke observed with poor SDOH, others have raised concerns regarding disparities in acute stroke care. This study aimed to determine the association between SDOH and the administration of thrombolytic therapy and mechanical thrombectomy among patients with acute ischemic stroke. A retrospective cohort analysis was conducted using Texas Emergency Department Public Use Data (2016-2019), including adult patients diagnosed with acute ischemic stroke. The risk ratios (RRs) of administering thrombolysis and thrombectomy based on variables representing SDOH and a collective measure (Social Vulnerability Index [SVI]) were computed using mixed-effects Poisson regression models accounting for the nested nature of patients in hospitals and neighborhoods. The Charlson comorbidity score was considered as a covariate. Of the 139,852 patients with ischemic stroke (female, 51.7%; White, 67.2%; Black, 16.6%; Hispanic, 25.1%), 16,831 (12.3%) received thrombolytic therapy and 5,951 (4.3%) received mechanical thrombectomy. Age older than 65 years (RR 0.578 [0.537-0.621]) vs 18-45 years, Black (RR 0.801 [0.761-0.844]) vs White, Hispanic (RR 0.936 [0.895-0.98]) vs non-Hispanic, Medicare/Medicaid/Veterans Affairs (VA) (RR 0.917 [0.882-0.954]) or uninsured (RR 0.883 [0.833-0.935]) vs private insurance, and rural (RR 0.782 [0.723-0.845]) vs urban dwelling were less likely to be associated with thrombolysis. Patients in the highest quintile based on the SVI were less likely to receive thrombolysis than those in the lowest quintile (RR 0.926 [0.867-0.989]). Patients were less likely to receive thrombectomy if they were 65 years and older (RR 0.787 [0.691-0.895]), belonged to the Black race (RR 0.745 [0.679-0.818]) or Hispanic ethnicity (RR 0.919 [0.851-0.992]), had Medicare/Medicaid/VA insurance (RR 0.909 [0.851-0.971]), or were from a rural area (RR 0.909 [0.851-0.971]). Similarly, SVI decreased the likelihood of undergoing mechanical thrombectomy (RR 0.842 [0.747-0.95]). Despite many improvements in stroke management, SDOH continue to be a significant driver of treatment access for acute ischemic stroke. While our findings are limited to Texas, our results should raise awareness and promote more studies regarding the effects of these SDOH at the national and international levels.

Acute stroke care in low and middle-income countries.

The purpose of this article is to discuss the global impact of stroke, the disparities and barriers to implement stroke care, and the global efforts to improve access to acute treatments in low and middle-income countries (LMICs). Disparities in access to stroke care are influenced by socioeconomic inequalities, geographic disparities, and limited healthcare infrastructure, particularly in LMICs. Effective stroke care requires a coordinated approach involving emergency services, rapid diagnosis, timely treatment, and early rehabilitation. However, there are significant delays in implementing evidence-based practices, particularly in areas where stroke care resources are scarce.Key barriers include geographic disparities, economic constraints, insufficient healthcare infrastructure, low public awareness, and weak policy frameworks. Addressing these challenges requires strengthening health systems, promoting universal health coverage, enhancing public and healthcare provider education, leveraging technology like telemedicine, and fostering international collaboration. Global efforts, including initiatives by the World Stroke Organization, focus on improving stroke care through infrastructure development, workforce training, and policy advocacy. These recommended strategies aim to make stroke care accessible and effective for everyone, regardless of location or socioeconomic status, ultimately helping to reduce the global burden of stroke.

Prevention of stroke and cognitive decline in pediatric population in resource-limited settings

There is an increasing global burden of pediatric stroke especially in low- and middle-income countries (LMICs). This is worsened by the specific risk factors in these areas, including Sickle Cell Disease and endemic infections like Tuberculosis and Human Immunodeficiency disease. Stroke occurs 221–300 times more frequently in patients with SCD when compared to healthy children. Although established stroke units and acute stroke care can improve outcomes, these are often not available in resource-poor settings. Primary and secondary prevention of strokes become a very important strategy to reduce the mortality and debilitating physical and cognitive long-term effects of stroke. There are myriads of challenges with implementing already established global policies and guidelines for stroke care in LMICs. These include paucity of data on this subject, poor knowledge and awareness about the symptoms of childhood stroke, adverse cultural beliefs regarding strokes, lack of screening and diagnostic equipment, inadequately trained manpower as well as nonexistent evidence-based management guidelines in these regions. To address these challenges, simple, cost-effective, stroke care models that determine the process of care and how available services should be delivered have been proposed to suit the peculiarities of LMICs in the areas of stroke risk assessment, prevention, and management.

How and why do community stakeholders participate in the national stroke audit in England? Findings from a mixed-method online survey

BackgroundNational audit programmes are a recognised means of assessing quality of healthcare by collecting and reporting data in relation to evidence-based standards. The Sentinel Stroke National Audit Programme is a prospective audit of processes and outcomes for all stroke patients in England, Wales and Northern Ireland which has historically focused on hospital-based care. Evidence suggests it has been successful in driving quality improvement. What has yet to be explored is the influence of such a national audit programme on community-based healthcare. The aims of this study were to understand how community stakeholders perceive and participate in the audit. MethodsThe study used a realist approach, being theory driven and informed by collaborators including stroke clinicians and experts in realist and audit methodology. Contextual determinants and mechanisms were identified from the literature as having the potential to influence quality improvement. These were operationalised into 18 survey items, using a combination of 5-point scales and yes / no responses. Free text options offered the opportunity to expand upon responses.The online survey was distributed using social media, clinical networks and professional bodies. Representation was sought from community stroke stakeholders across England and from roles throughout the audit process including administrative, clinical, management and commissioning. ResultsThe survey achieved a national sample from a broad range of stakeholders (n=206). Participants reported being engaged in the audit, committing significant resources to participation. National audit feedback was described as being used to support a range of improvement activities, including funding for additional staff and service reorganisation. A number of factors influenced the ability of teams to participate in audit and utilise feedback for quality improvement. These included the online platform, the accuracy of data submitted and leadership support.ConclusionsFindings highlight the work needed in terms of the data captured, organisational audit support and engagement with feedback if the potential of the audit as a tool for quality improvement in community rehabilitation (as highlighted in acute stroke care) is to be realised.

A Hybrid Simulation‐Based Workshop Improves Knowledge and Confidence in the Management of Hemorrhagic Conversion of Stroke Among Interventional Neurology Trainees

Background Mechanical thrombectomy is the standard of care in acute ischemic stroke with anterior large vessel occlusion presenting within 6 hours of symptom onset, but complications do exist. We assessed the feasibility of a hybrid simulation‐based workshop at a national meeting for interventional neurology trainees focused on the management of acute ischemic stroke and tissue‐plasminogen activator‐related hemorrhage. Methods In this prospective, observational, hybrid simulation‐based study at a fellows’ workshop at a national conference, participants were asked to manage a patient with acute ischemic stroke in the neurointerventional suite followed by thrombolytic‐related hemorrhage leading to cerebral herniation during mechanical thrombectomy. We evaluated the participants’ ability to complete critical actions that were developed based on best practices and relevant American Heart Association guidelines and the Neurocritical Care Society's Emergency Neurological Life Support protocols. The primary outcome was the improvement in knowledge from a precourse to postcourse test. Secondary outcomes included participant reactions. Results Sixty trainees completed the simulation session in 8 groups. The mean sum of critical actions completed by trainees was 9.75/14 (70%). There was a moderate effect of the intervention on trainees’ knowledge from pretest (mean 3.8, SD = 0.3) to posttest (mean 4.3, SD = 0.3). The simulation scenario was described as moderately realistic, very engaging, and extremely satisfactory. Following the workshop, all fellows endorsed an increase in proficiency and confidence in neurological emergency management. Conclusion Simulation‐based workshops at national conferences are feasible and a potentially useful tool for safely educating a large audience of trainees who may not have access to high‐fidelity simulation platforms at their institutions.

Impact of quality of care on outcomes in survivors of stroke with aphasia: A linked registry and hospital data observational study

BackgroundThe impact of hospital care quality on patient outcomes in post-stroke aphasia remains unclear. We investigated the impact of nationally-endorsed acute stroke treatments on outcomes post-stroke, by aphasia status. MethodsPatient-level data from the Australian Stroke Clinical Registry (2009–2013) linked to national deaths, hospital emergency presentations and admissions data were used. Aphasia was identified for the index stroke event (ICD-10 diagnosis code R47.0). Impact of receiving an optimal stroke care bundle (stroke unit care, antihypertensive medication at discharge and discharge care plan) and an acute ischemic stroke (AIS) care bundle (stroke unit care, intravenous thrombolysis and aspirin within 48 h of admission) on outcomes were analysed using multivariable regression models with propensity score adjustment. ResultsThe study included 12,690 patients with a median age of 76, 54 % male, and 26 % with aphasia. Non-receipt of the optimal stroke care bundle was associated with worse survival, compared to optimal care, in people with aphasia (HR: 3.37; 95 % CI 2.10, 5.40; p < 0.05) and without aphasia (HR: 2.10; 95 % CI 1.19, 3.69; p < 0.05). Notably, the dose-response effect on survival was more pronounced in individuals with aphasia. In those who received the AIS care bundle, readmission within 12 months was greater in those without aphasia (vs aphasia, p-value interaction = 0.001), whereas survival was similar (p-value interaction = 0.731). ConclusionsSurvivors of stroke with aphasia who did not receive the optimal stroke care bundle, had worse survival at 12 months post-stroke. Ensuring eligible patients receive the optimal stroke care bundle is crucial for improving their 12-month survival.

Chronic Illness and visiting clinic before hospitalization at the onset of Stroke: Shiga Registry

Abstract Background Prompt action at stroke onset is required to improve prognosis. Some previous studies indicated that visiting local clinics may initially delay access to specialized care. We examined the relationship between the presence of chronic diseases known as risk factors for stroke and visiting a local clinic before admission to the hospital for acute stroke care. Methods This study utilized data from stroke patients aged 18 and older who were registered in the Shiga Stroke and Heart Attack Registry (SSHR) from January 2011 to December 2015. We excluded cases with onset during hospitalization or those with impaired consciousness assessed by the Japan Coma Scale (JCS &amp;gt; =10). The presence of comorbid chronic diseases was determined based on the past history and medications presented at admission. Local clinics are defined as clinics or hospitals that are not equipped to provide acute stroke treatment. Multivariate logistic regression analyses, adjusting for sex, age, modified Rankin Scale score before onset, and stroke subtypes, were performed to calculate odds ratios and 95% confidence intervals for visiting a clinic before hospitalization according to the presence of chronic diseases such as hypertension, diabetes, dyslipidemia, and atrial fibrillation, respectively. Results Data from 11,111 out of 14,620 registered cases were analyzed. Among these participants, 5,774 had hypertension, 1,951 had diabetes, 2,111 had dyslipidemia, and 882 had atrial fibrillation. A total of 2,405 (21.6%) cases visited a local clinic at stroke on set. The adjusted odds ratios for visiting clinics by the presence of hypertension were (1.22, 95% CI: 1.11 -1.34), diabetes (1.14, 1.01-1.28), dyslipidemia (1.07, 0.95 -1.20), and atrial fibrillation (0.80, 0.67 -0.95). Conclusions The present study indicated that individuals with hypertension and/or diabetes are more likely to initially visit a local clinic at stroke onset, whereas those with atrial fibrillation were not. Key messages • Approximately 20% of mild stroke patients first consult local or primary care doctors at stroke onset. This trend was particularly observed in individuals with hypertension and diabetes. • Emphasizing the need for direct access to specialized emergency care for individuals with chronic diseases is important to avoid delays in acute stroke care.

Time-Sensitive Quality Metrics of Acute Stroke Care: A Comprehensive Stroke Center Experience

Time-Sensitive Quality Metrics of Acute Stroke Care: A Comprehensive Stroke Center Experience

From ‘strong recommendation’ to practice: A pre-test post-test study examining adherence to stroke guidelines for fever, hyperglycaemia, and swallowing (FeSS) management post-stroke

BackgroundThe Quality in Acute Stroke Care (QASC) Trial demonstrated that assistance to implement protocols to manage Fever, hyperglycaemia (Sugar) and Swallowing (FeSS) post-stroke reduced death and disability. In 2017, a ‘Strong Recommendation’ for use of FeSS Protocols was included in the Australian Clinical Guidelines for Stroke Management. We aimed to: i) compare adherence to FeSS Protocols pre- and post-guideline inclusion; ii) determine if adherence varied with prior participation in a treatment arm of a FeSS Intervention study, or receiving treatment in a stroke unit; and compare findings with our previous studies. MethodsPre-test post-test study using Australian acute stroke service audit data comparing 2015/2017 (pre-guideline) versus 2019/2021 (post-guideline) adherence. Primary outcome was adherence to all six FeSS indicators (composite), with mixed-effects logistic regression adjusting for age, sex, stroke type and severity (ability to walk on admission), stroke unit care, hospital prior participation in a FeSS Intervention study, and correlation of outcomes within hospital. Additional analysis examined interaction effects. ResultsOverall, 112 hospitals contributed data to ≥1 one Audit cycle for both periods (pre=7011, post=7195 cases); 42 hospitals had participated in any treatment arm of a FeSS Intervention study. Adherence to FeSS Protocols post-guideline increased (pre: composite measure 35% vs post: composite measure 40 %, aOR:1.2 95 %CI: 1.2, 1.3). Prior participation in a FeSS Intervention study (aOR:1.6, 95 %CI: 1.2, 2.0) and stroke unit care (aOR 2.3, 95 %CI: 2.0, 2.5) were independently associated with greater adherence to FeSS Protocols. There was no change in adherence over time based on prior participation in a FeSS Intervention study (p = 0.93 interaction), or stroke unit care (p = 0.07 interaction). ConclusionsThere is evidence of improved adherence to FeSS Protocols following a ‘strong recommendation’ for their use in the Australian stroke guidelines. Change in adherence was similar independent of hospital prior participation in a FeSS Intervention study, or stroke unit care. However, maintenance of higher pre-guideline adherence for hospitals prior participation in a FeSS Intervention study suggests that research participation can facilitate greater guideline adherence; and confirms superior care received in stroke units. Nevertheless, less than half of Australian patients are being cared for according to the FeSS Protocols, providing impetus for additional strategies to increase uptake.

Quality in Acute Stroke Care (QASC) Germany: improving efficiency in stroke care with nurse-initiated FeSS-protocols

BackgroundNurse-initiated supported implementation of protocols to manage fever, hyperglycaemia (sugar) and swallowing (FeSS) following acute stroke reduced 90-day death and disability in the landmark Australian Quality in Acute Stroke Care (QASC)-Trial. An international interprofessional collaboration sought to evaluate the effects of nurse-led FeSS implementation on FeSS Protocol adherence in German stroke units.MethodsThis pre-test/post-test study was conducted in eight German stroke units between 2020 and 2022. Stroke nurses as clinical champions, supported by the project team, conducted multidisciplinary workshops discussing pre-implementation medical record audit results, barriers and facilitators to FeSS Protocol implementation, developed action plans and provided education, with ongoing support from Australia. Medical record audit data were collected by nurses, pre-implementation and three months post-implementation.ResultsIn 771 (pre-implementation) and 679 (post-implementation) patients there were improvements in overall FeSS adherence (pre 20%, post 28%; adjusted difference in proportions (95% CI) 11%, (5.1%, 16%); p < 0.001), adherence to hyperglycaemia (pre 43%, post 55%; adjusted difference 23%, (17%, 29%); p < 0.001) and swallowing (pre 52%, post 61%; adjusted difference 11%, (5.2%, 17%); p < 0.001) but not fever protocol (pre 76%, post 78%; adjusted difference 1.5%, (-2.6%, 5.7%); p = 0.474). Improvements also were noted in administration of anti-pyretics (pre 29%, post 59%; adjusted difference 32%, (20%, 44%); p < 0.001); and insulin (pre 41%, post 60%; adjusted difference 14%, (1.1%, 28%); p < 0.034) both within one hour, as well as in performing a swallow screen within 24 h of admission (pre 65%, post 74%; adjusted difference 18% (8.8%, 26%); p < 0.001).ConclusionsSupported implementation of the FeSS Protocols significantly improved acute care for post stroke complications of fever, hyperglycaemia and dysphagia in terms of higher adherence and shorter time to treatment.Trial registrationAs this is a pre-test/post-test study and does not meet the WHO/ICMJE definition of a clinical trial, registration was not required.

Clinically relevant findings on 24-h head CT after acute stroke therapy: The 24-h CT score.

Routine head computed tomography (CT) is performed 24 h post-acute stroke thrombolysis and thrombectomy, even in patients with stable or improving clinical deficits. Predicting CT results that impact management could help prioritize patients at risk and potentially reduce unnecessary imaging. In this institutional review board (IRB)-approved retrospective study, data from 1461 consecutive acute ischemic stroke patients at our Comprehensive Stroke Center (n = 8943, 2012-2022) who received intravenous thrombolysis or endovascular therapy, exhibited stable or improving 24-h exams, and underwent 24-h follow-up head CT per standard acute stroke care guidelines. CT reports 24 h post-stroke were reviewed for edema, mass effect, herniation, and hemorrhage. The primary outcome was any clinically relevant 24-h CT finding that led to changes in antithrombotic treatment or blood pressure goals, extended intensive care unit (ICU) stays or hospitalizations, neurosurgical interventions, or administration of mannitol or hypertonic saline. Multivariable logistic regression identified independent predictors of clinically meaningful CT abnormalities. A 24-h CT score was developed and cross-validated. The mean age was 70 years, with 47% women. The median National Institutes of Health Stroke Scale (NIHSS) score at admission was 12 (interquartile range (IQR): 6-18). Stroke-related abnormalities on 24-h CT were present in 325 patients (22.2%), with 183 (12.5%) showing clinically relevant findings. Age, admission NIHSS, and blood glucose levels were independent predictors of clinically relevant 24-h CT findings. The final model C statistic was 0.72 (95% confidence interval (CI): 0.68-0.76) in the derivation cohort and 0.72 (95% CI: 0.67-0.75) in bootstrapping validation. The 24-h CT score was developed using these predictors: NIHSS score 5-15 (+3); NIHSS score ⩾16 (+5); age < 75 years (+1); admission glucose ⩾ 140 mg/dL (+1). The prevalence of clinically relevant CT findings was 4.3% in the low-risk group (24-h CT score ⩽ 4), 11.3% in the medium-risk group (score 5), and 21.4% in the high-risk group (score ⩾ 6). The 24-h CT score demonstrated good calibration. In patients undergoing thrombolysis or thrombectomy who undergo routine 24-h head CT despite remaining clinically stable or improving, only one in eight prove to have 24-h head CT findings that impact management. The 24-h CT score provides risk stratification that may improve resource utilization. A.S. and B.Z. have full access to the data used in the analysis in this article. Deidentified data will be shared after ethics approval if requested by other investigators for purposes of replicating the results.

Telestroke Training: Considerations for Expansion of Vascular Neurology Program Requirements.

Telemedicine for stroke (Telestroke) has been a key component to efficient, widespread acute stroke care for many years. The expansion of reimbursement through the Furthering Access to Stroke Telemedicine Act and rapid deployment of telemedicine resources during the COVID-19 public health emergency have further expanded remote care, with practitioners of varying educational backgrounds, and experience providing acute stroke care via telemedicine (Telestroke). Some Telestroke practitioners have not had fellowship-level vascular neurology training and many are without training specific to virtual modalities. While many vascular neurology fellowship programs incorporate Telestroke training into the curriculum, components of this curriculum are not consistent, extent of involvement is variable, and not all fellows receive hands-on training in remote care. Furthermore, the extent of training and evaluation of Telestroke in American Board of Psychiatry and Neurology training requirements and Accreditation Council for Graduate Medical Education assessments for vascular neurology fellowship are not standardized. We suggest that Telestroke be formally incorporated into vascular neurology fellowship curricula and provide considerations for key components of this training and metrics for evaluation.

Characteristics, clinical profiles, and outcomes of patients undergoing endovascular thrombectomy: A retrospective study, Saudi Arabia

BackgroundStroke is a significant contributor to both mortality and compromised physical function. Endovascular thrombectomy (EVT) is now the recognized standard of care for anterior circulation acute ischemic stroke (AIS) with large vessel occlusion (LVO), especially when favorable brain images are evident within 24 h of symptom onset. This study elucidated the characteristics, clinical profiles, and outcomes of patients who underwent EVT for AIS. MethodologyIn this retrospective record-based cohort study, we reviewed the medical records of individuals who underwent EVT for AIS at King Fahad General Hospital in Jeddah, Saudi Arabia. The study, conducted from July 2022 through October 2023, encompassed a comprehensive analysis of clinical, radiological, and time-related factors and diverse outcomes. ResultsIn a cohort of 117 patients with a mean age of 58.5 years, 81 (69.2%) were male. Hypertension and diabetes mellitus were the most common risk factors, affecting 48.7% and 41% of the cohort, respectively. Approximately half of the patients had a favorable ASPECT Score (7–10), and 45.3% received intravenous tissue plasminogen activator (tPA). Nearly two-thirds achieved a modified thrombolysis in cerebral infarction (mTICI) score of 2b or higher, and 39.3% exhibited M1-middle cerebral artery (MCA) occlusion. The incidence of symptomatic hemorrhagic transformation was about 13%, whereas one-third of the patients attained a favorable mRs outcome (0–2). Factors such as advanced age, higher NIH Stroke Scale (NIHSS) scores, and prolonged hospital stays were associated with poorer outcomes. Conversely, the absence of hypertension and atrial fibrillation, along with higher TICI scores, significantly increased the likelihood of favorable outcomes, with P values of 0.015, 0.0490, and 0.025, respectively. ConclusionsIn our study, the examined patients who underwent EVT were younger in age, with clinical and radiological outcomes showing some degree of comparability to other publications. Notably, the absence of hypertension and atrial fibrillation, combined with a higher TICI score, was associated with an increased likelihood of achieving a favorable outcome.

National assessment of clinicians participating in stroke treatment decisions at strokenet regional coordinating centers: Clinicians Making Stroke Treatment Decisions

ObjectivesSince the introduction of thrombolytics, stroke teams evolved to improve thrombolytic care delivery. The impact of the advent of endovascular therapy on the composition of acute stroke teams is unknown. Materials and MethodsA two-part pilot-tested survey was deployed to site-Principal Investigators (PIs) of the 27 StrokeNet Regional Coordinating Centers (RCCs) regarding institutional acute stroke teams. Part A inquired about the participation of personnel in each type of stroke response. Part B identified stroke team physicians and the types of responses in which they participate to assess training background of stroke team members. ResultsResponse rates for Part A and B were 66% and 48%, respectively. In Part A, 67% (12/18) of sites reported trainees always responded to ED stroke activations with significant autonomy. 44% (7/16) and 27% (4/15) of sites reported NP and PA response to ED stroke alerts, respectively, but with limited autonomy. In Part B, 124 physicians involved in ED stroke alerts were identified, the large majority of whom (79%, 95% CI: 71-85) were vascular neurology trained. The 39 (23%) stroke team members involved in endovascular therapy had the following training: 49% (34-64) neurosurgery, 28% (17-44) radiology, 18% (9-33) vascular neurology 5% (1-16) neurology. ConclusionsWe identified modest heterogeneity in the composition of acute stroke team members across StrokeNet RCCs. Individuals performing endovascular therapy had a variety of clinical specializations, reflecting the evolving multidisciplinary nature of interventional acute stroke care. At StrokeNet RCCs, teams have significant trainee involvement in both ED and inpatient acute stroke responses.

Dyselectrolytaemia in Acute Stroke Patients, A Study of Hundred Cases in Holy Family Red Crescent Medical College Hospital

Introduction: Stroke is a growing public health concern in low- and middle-income countries. There are many studies on stroke, its associated conditions, and its effect on stroke patients’ outcomes, but few studies on dyselectrolytaemia in stroke patients have been done in our country. This study aimed to highlight the pattern and correlation of dyselectrolytaemia in acute stroke patients of a tertiary care hospital. Methods: This cross-sectional study was conducted in the Department of Medicine, Holy Family Red Crescent Medical College Hospital, from January, 2016 to June, 2016. A total of 100 patients with stroke were selected as study subjects as per inclusion and exclusion criteria. Statistical analyses were carried out by using the Statistical Package for Social Sciences version 20.0 for Windows. The mean values were calculated for continuous variables. The quantitative observations were indicated by frequencies and percentages. The chi-square test with Yates correction was used to analyze the categorical variables. Student t-test was used for continuous variables. P values &lt;0.05 were considered statistically significant. Result: In this study, 31 (31.0%) patients had dyselectrolytaemia. This study shows serum electrolytes of the study patients, it was observed that 17(17.0%) patients had hyponatremia: serum sodium level (&lt;135 mmol/I), 13(13.0%) patients had hypokalaemia serum potassium (&lt;3.5 mmol/l), 16(16.0%) patients had hypochloraemia serum Chloride level (&lt;96 mmol/l) and 11(11.0%) patients had low bicarbonate level (&lt; 24 mmol/I). Conclusion: This study highlights the prevalence of dyselectrolytaemia in acute stroke patients. Among the 100 patients studied, 17% experienced hyponatremia, 13% had hypokalaemia, 16% exhibited hypochloraemia, and 11% had low bicarbonate levels. These findings highlight the importance of routine electrolyte monitoring and prompt management in acute stroke care to prevent complications and improve patient outcomes.

Optimizing Acute Ischemic Stroke Care: Evaluating Emergency Stroke Code Activation and Thrombolytic Therapy in East Azerbaijan Province

Background: Stroke remains a significant global health challenge, contributing to mortality and disability burdens. Optimizing stroke care involves understanding the complexities of in-hospital management, especially in regions like East Azerbaijan Province, where stroke incidence is high. Objectives: This study evaluates the effectiveness of Emergency Stroke Code (ESC) activation and thrombolytic therapy in acute ischemic stroke care at Imam Reza Hospital, Tabriz, a referral center. Methods: A cross-sectional study was carried out between April 2021 and March 2022, including patients with activated ESC or receiving thrombolysis at Imam Reza Hospital, Tabriz. Data on patient demographics, risk factors, time intervals, thrombolysis administration, adverse events, and outcomes were collected and analyzed using SPSS software. Results: Among 748 acute stroke patients, 165 received thrombolysis, with 117 having ESC activation. The main reasons for not administering tissue plasminogen activator (tPA) in patients with ESC code activation included mild symptoms (23.6%), exceeding thrombolysis time (14.8%), and hemorrhagic stroke (10.4%). Pre-hospital ESC activation significantly reduced time intervals from hospital arrival to CT-scan and tPA injection (P &lt; 0.001). The incidence of intracranial hemorrhage was 6.7% overall, with rare systemic bleeding (0.6%). Pre-hospital notification did not show significant changes in the National Institutes of Health Stroke Scale (NIHSS) or Modified Rankin Scale (MRS) scores. Conclusions: While ESC activation streamlines in-hospital processes, it alone may not improve clinical outcomes without efficient out-of-hospital systems. Pre-hospital communication systems like ESC can aid in reducing in-hospital processing time for thrombolysis but must be coupled with efforts to enhance early diagnosis and efficient dispatch systems to optimize stroke care.

Emergency Department Process Times and Door-In-Door-Out Times in Interhospital Transfers After Acute Ischemic Stroke.

Stroke treatment is exquisitely time sensitive. The door-in-door-out (DIDO) time, defined as the total time spent in the emergency department (ED) at a transferring hospital, is an important quality metric for the care of acute stroke. However, little is known about the contributions of specific process steps to delays and disparities in DIDO time. To quantify process steps and their association with DIDO times at transferring hospitals among patients with acute ischemic stroke (AIS). This retrospective cohort study analyzed patients in the American Heart Association Get With the Guidelines-Stroke registry with AIS presenting between January 1, 2019, to December 31, 2021, and transferred from the presenting hospital ED to another acute care hospital for evaluation of thrombolytics, endovascular therapy, or postthrombolytic care. Data were analyzed from July 8 to October 13, 2023. Intervals of ED care of ischemic stroke: door-to-imaging and imaging-to-door times. The primary outcome was DIDO time. Multivariate generalized estimating equations regression models were performed to compare contributions of interval process times to explain variation in DIDO time, controlling for patient- and hospital-level characteristics. Among 28 887 patients (50.5% male; mean [SD] age, 68.3 [14.8] years; 5.5% Hispanic, 14.7% non-Hispanic Black, and 73.2% non-Hispanic White), mean (SD) DIDO time was 171.4 (149.5) minutes, mean (SD) door-to-imaging time was 18.3 (34.1) minutes, and mean (SD) imaging-to-door time was 153.1 (141.5) minutes. In the model adjusting for door-to-imaging time, the following were associated with longer DIDO time: age 80 years or older (compared with 18-59 years; 5.97 [95% CI, 1.02-10.92] minutes), female sex (5.21 [95% CI, 1.55-8.87] minutes), and non-Hispanic Black race (compared with non-Hispanic White 10.09 [95% CI, 4.21-15.96] minutes). In the model including imaging-to-door time as a covariate, disparities in DIDO by age and female sex became nonsignificant, and the disparity by Black race was attenuated (2.32 [95% CI, 1.09-3.56] minutes). In this national cohort study of interhospital transfer of patients with AIS, delays in DIDO time by Black race, older age (≥80 years), and female sex were largely explained by the imaging-to-door period, suggesting that future systems interventions should target this interval to reduce these disparities. While existing guidelines and care resources heavily focus on reducing door-to-imaging times, further attention is warranted to reduce imaging-to-door times in the management of patients with AIS who require interhospital transfer.

Racial and ethnic differences in access to care and treatment in patients with suspected acute stroke: A retrospective, observational, cohort study

BackgroundData regarding unequal diagnostic and therapeutic access in patients with acute stroke based on ethnicity and race are inconclusive in Europeans. The objectives of our study were to evaluate the effect of race/ethnicity on access to acute stroke care and treatments and outcomes. MethodsIn this retrospective cohort study, we enrolled adult patients admitted to the emergency department of a comprehensive stroke center for suspected stroke. Based on race/ethnicity, patients were divided into two main groups: Western European Whites (WEW) and non-Western European Whites (nWEW). We also divided the nWEW group into four subgroups based on the Office of Management and Budget classification of human races and ethnicities (White-Others, Hispanic, Asian, Black). Univariate comparisons and logistic regression analyses were also performed. Results9167 patients were enrolled in the study: 582 in the nWEW and 8585 in the WEW group. Patients with ischemic stroke in the nWEW group were significantly younger than those in the other group (p < 0.001). Once adjusted for possible confounders, belonging to the nWEW group was found to be an independent predictor of a lower likelihood of receiving revascularization treatments (p = 0.006), regardless similar onset-to-door times. There were no differences in stroke outcomes and prevalence of stroke mimic diagnosis between the groups. ConclusionsRacial/ethnic disparities in healthcare represent a challenging issue, even in universal healthcare systems, that should be addressed promptly through education campaigns of healthcare personnel and implementation measures, such as integrating readily available interpreter staff for medical emergencies.
