Abstract
BACKGROUND Delays in hospital presentation limit access to acute stroke treatments. While prior research has focused on patient-level factors, broader ecological and social determinants have not been well studied. We aimed to create a geospatial map of prehospital delay and examine the role of community-level social vulnerability. METHODS We studied patients with ischemic stroke who arrived by emergency medical services in 2015 to 2017 from the American Heart Association Get With The Guidelines-Stroke registry. The primary outcome was time to hospital arrival after stroke (in minutes), beginning at last known well in most cases. Using Geographic Information System mapping, we displayed the geography of delay. We then used Cox proportional hazard models to study the relationship between community-level factors and arrival time (adjusted hazard ratios [aHR] <1.0 indicate delay). The primary exposure was the social vulnerability index (SVI), a metric of social vulnerability for every ZIP Code Tabulation Area ranging from 0.0 to 1.0. RESULTS Of 750 336 patients, 149 145 met inclusion criteria. The mean age was 73 years, and 51% were female. The median time to hospital arrival was 140 minutes (Q1: 60 minutes, Q3: 458 minutes). The geospatial map revealed that many zones of delay overlapped with socially vulnerable areas (https://harvard-cga.maps.arcgis.com/apps/webappviewer/index.html?id=08f6e885c71b457f83cefc71013bcaa7). Cox models (aHR, 95% CI) confirmed that higher SVI, including quartiles 3 (aHR, 0.96 [95% CI, 0.93-0.98]) and 4 (aHR, 0.93 [95% CI, 0.91-0.95]), was associated with delay. Patients from SVI quartile 4 neighborhoods arrived 15.6 minutes [15-16.2] slower than patients from SVI quartile 1. Specific SVI themes associated with delay were a community's socioeconomic status (aHR, 0.80 [95% CI, 0.74-0.85]) and housing type and transportation (aHR, 0.89 [95% CI, 0.84-0.94]). CONCLUSIONS This map of acute stroke presentation times shows areas with a high incidence of delay. Increased social vulnerability characterizes these areas. Such places should be systematically targeted to improve population-level stroke presentation times.

Healthcare (Basel) 2024; 12:966. [PMID: 38786378 PMCID: PMC11120760 DOI: 10.3390/healthcare12100966] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2024] [Revised: 04/22/2024] [Accepted: 05/02/2024] [Indexed: 05/25/2024] Open
Abstract
BACKGROUND AND PURPOSE Early differentiation between acute ischaemic (AIS) and haemorrhagic stroke (ICH), based on cerebral and peripheral hemodynamic parameters, would be advantageous to allow for pre-hospital interventions. In this preliminary study, we explored the potential of multiple parameters, including dynamic cerebral autoregulation, for phenotyping and differentiating each stroke sub-type. METHODS Eighty patients were included with clinical stroke syndromes confirmed by computed tomography within 48 h of symptom onset. Continuous recordings of bilateral cerebral blood velocity (transcranial Doppler ultrasound), end-tidal CO2 (capnography), electrocardiogram (ECG), and arterial blood pressure (ABP, Finometer) were used to derive 67 cerebral and peripheral parameters. RESULTS A total of 68 patients with AIS (mean age 66.8 ± SD 12.4 years) and 12 patients with ICH (67.8 ± 16.2 years) were included. The median ± SD NIHSS of the cohort was 5 ± 4.6. Statistically significant differences between AIS and ICH were observed for (i) an autoregulation index (ARI) that was higher in the unaffected hemisphere (UH) for ICH compared to AIS (5.9 ± 1.7 vs. 4.9 ± 1.8 p = 0.07); (ii) coherence function for both hemispheres in different frequency bands (AH, p < 0.01; UH p < 0.02); (iii) a baroreceptor sensitivity (BRS) for the low-frequency (LF) bands that was higher for AIS (6.7 ± 4.2 vs. 4.10 ± 2.13 ms/mmHg, p = 0.04) compared to ICH, and that the mean gain of the BRS in the LF range was higher in the AIS than in the ICH (5.8 ± 5.3 vs. 2.7 ± 1.8 ms/mmHg, p = 0.0005); (iv) Systolic and diastolic velocities of the affected hemisphere (AH) that were significantly higher in ICH than in AIS (82.5 ± 28.09 vs. 61.9 ± 18.9 cm/s), systolic velocity (p = 0.002), and diastolic velocity (p = 0.05). CONCLUSION Further multivariate modelling might improve the ability of multiple parameters to discriminate between AIS and ICH and warrants future prospective studies of ultra-early classification (<4 h post symptom onset) of stroke sub-types.

Abstract
BACKGROUND Stroke is a common and severe disease that requires prompt care. Symptom expressions as one-sided weakness and speech difficulties are common and included in public stroke campaigns. For some patients stroke can present with subtle and less common symptoms, difficult to interpret. The symptom severity assessed by the National Institutes of Health Stroke Scale has decreased, and symptoms at onset may have changed. Therefore, we aimed to investigate how patients describe their symptoms at the onset of a first-time stroke. METHODS The study used a qualitative descriptive design and conventional content analysis. Data were collected through recorded interviews with 27 patients aged 18 years and older hospitalised with a first-time stroke between October 2018 and April 2020. Data were analysed on a manifest level. RESULTS Symptoms at stroke onset were presented in two themes: Altered Reality and Discomfort and Changed Body Functions and described in five categories. Various types of symptoms were found. All symptoms were perceived as sudden, persistent, and never experienced before and this appear as a "red thread" in the result. Regardless of symptom expressions, no specific symptom was described as more severe than another. CONCLUSIONS Stroke symptoms were described with a variety of expressions. Many described complex symptoms not typical of stroke, which can make it difficult to recognise the symptoms as a stroke and delay medical care. Public stroke campaigns should emphasize the importance of seeking medical care at the slightest suspicion of stroke and could be designed to help achieve this.

BMJ Open 2024; 14:e079316.

Abstract
INTRODUCTION Prehospital identification of intracerebral haemorrhage (ICH) in suspected stroke cases may enable the initiation of appropriate treatments and facilitate better-informed transport decisions. This scoping review aims to examine the literature to identify early clinical features and portable devices for the detection of ICH in the prehospital setting. METHODS Three databases were searched via Ovid (MEDLINE, EMBASE and CENTRAL) from inception to August 2022 using prespecified search strategies. One reviewer screened all titles, abstracts and full-text articles for eligibility, while a second reviewer independently screened 20% of the literature during each screening stage. Data extracted were tabulated to summarise the key findings. RESULTS A total of 6803 articles were screened for eligibility, of which 22 studies were included for analysis. Among them, 15 studies reported on early clinical features, while 7 considered portable devices. Associations between age, sex and comorbidities with the presence of ICH varied across studies. However, most studies reported that patients with ICH exhibited more severe neurological deficits (n=6) and higher blood pressure levels (n=11) at onset compared with other stroke and non-stroke diagnoses. Four technologies were identified for ICH detection: microwave imaging technology, volumetric impedance phase shift spectroscopy, transcranial ultrasound and electroencephalography. Microwave and ultrasound imaging techniques showed promise in distinguishing ICH from other diagnoses. CONCLUSION This scoping review has identified potential clinical features for the identification of ICH in suspected stroke patients. However, the considerable heterogeneity among the included studies precludes meta-analysis of available data. Moreover, we have explored portable devices to enhance ICH identification. While these devices have shown promise in detecting ICH, further technological development is required to distinguish between stroke subtypes (ICH vs ischaemic stroke) and non-stroke diagnoses.

Association of Neighborhood-Level Socioeconomic Factors With Delay to Hospital Arrival in Patients With Acute Stroke. Neurology 2024; 102:e207764. [PMID: 38165368 PMCID: PMC10834135 DOI: 10.1212/wnl.0000000000207764] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2023] [Accepted: 10/03/2023] [Indexed: 01/03/2024] Open
Abstract
BACKGROUND AND OBJECTIVES Delivery of acute ischemic stroke (AIS) therapies is contingent on the duration from last known well (LKW) to emergency department arrival time (EDAT). One reason for treatment ineligibility is delay in presentation to the hospital. We evaluate patient and neighborhood characteristics associated with time from LKW to EDAT. METHODS This was a retrospective observational study of patients presenting to the Yale New Haven Hospital in the AIS code pathway from 2010 to 2020. Patients presenting within 4.5 hours from LKW who were recorded in the institutional Get With the Guidelines Stroke registry were classified as early while those presenting beyond 4.5 hours were designated as late. Temporal trends in late presentation were explored by univariate logistic regression. Using variables significant in univariate analysis at p < 0.05, we developed a mixed-effect logistic regression model to estimate the probability of late presentation as a function of patient-level and neighborhood (ZIP)-level characteristics (area deprivation index [ADI] derived from the Health Resources and Services Administration), adjusted for calendar year and geographic distance from the centroid of the ZIP code to the hospital. RESULTS A total of 2,643 patients with AIS from 2010 to 2020 were included (63.4% presented late and 36.6% presented early). The frequency of late presentation increased significantly from 68% in 2010 to 71% in 2020 (p = 0.002) and only among non-White patients. Patients presenting late were more likely to be non-White (37.1% vs 26.9%, p < 0.0001), arrive by means other than emergency medical services (EMS) (32.7% vs 16.1%, p < 0.0001), have an NIHSS <6 (68.7% vs 55.2%, p < 0.0001), and present from a neighborhood with a higher ADI category (p = 0.0001) that was nearer to the hospital (median 5.8 vs 7.7 miles, p = 0.0032). In the mixed model, the ADI by units of 10 (odds ratio [OR] 1.022, 95% confidence interval [CI] 1.020-1.024), non-White race (OR 1.083, 95% CI 1.039-1.127), arrival by means other than EMS (OR 1.193, 95% CI 1.145-1.124), and an NIHSS <6 (OR 1.085, 95% CI 1.041-1.129) were associated with late presentation. DISCUSSION In addition to patient-level factors, socioeconomic deprivation of neighborhood of residence contributes to delays in hospital presentation for AIS. These findings may provide opportunities for targeted interventions to improve presentation times in at-risk communities.

J Stroke Cerebrovasc Dis 2024; 33:107431. [PMID: 37951082 DOI: 10.1016/j.jstrokecerebrovasdis.2023.107431] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2023] [Revised: 10/12/2023] [Accepted: 10/12/2023] [Indexed: 11/13/2023] Open
Abstract
OBJECTIVES To investigate the 10-year trend in healthcare quality of intravenous thrombolysis (IVT) with recombinant tissue plasminogen activator in acute ischemic stroke (AIS) in China. MATERIALS AND METHODS We analyzed 42,188 AIS within 7 days of onset from the China National Stroke Registry (CNSR) Ⅰ-Ⅲ. Primary outcomes were temporal changes in the proportion of patients arriving at the hospital within 3.5 hours (and 2 hours) of onset and receiving IVT within 4.5 hours (and 3 hours), stratified by region and hospital tier. Secondary outcomes included temporal changes in door-to-needle time (DNT), DNT ≤60 min and favorable outcome defined as a 90-day modified Rankin Scale (mRS) of 0-1. RESULTS Among patients arriving at the hospital within 3.5 hours of onset, 13.5%, 7.1% and 33.4% patients received IVT within 4.5 hours in CNSR Ⅰ, Ⅱ and Ⅲ, respectively, including a higher proportion from eastern China (37.0%) and tertiary hospitals (36.5%). The median DNT was shorter in CNSR Ⅲ (60.0 min) than those in Ⅱ (95.0 min) and I (94.0 min). The proportion of patients with DNT ≤60 min was greater in Ⅲ (53.4%) than those in Ⅱ (26.7%) and Ⅰ (13.4%). The proportion of favorable outcomes was higher in CNSR Ⅲ (72.8%) than those in Ⅱ (49.6%) and Ⅰ (49.4%). Similar trends were observed for patients arriving at the hospital within 2 hours and receiving IVT within 3 hours of onset. CONCLUSIONS The healthcare quality of IVT has improved remarkably in the past decade, notably in eastern China and tertiary hospitals.

Non-compliance with medical recommendations results in delayed hospitalization and poorer prognosis in patients with cerebral ischemic stroke in Poland: Non-compliance effects on post-ischemic stroke prognosis. J Stroke Cerebrovasc Dis 2024; 33:107465.

Abstract
OBJECTIVES This study aimed to reveal and analyze the causes of delays in reaching the hospital of patients with cerebral ischemic stroke and to assess their clinical picture. MATERIAL AND METHODS The study group included 161 patients with stroke, who reported to the hospital beyond the thrombolytic treatment therapeutic window. The control group consisted of 85 patients recruited consecutively with stroke who received thrombolytic treatment per eligibility criteria. Laboratory and medical imaging tests essential for neurological condition assessment were conducted in the study group. Control group research was based on retrospective analysis of medical records. RESULTS The rate of deaths during hospitalization was lower in the control group (4.7%) compared to the study group (14.9%). In the study group, more patients (16.8%) admitted to non-compliance with medical recommendations than in the control group (5.9%). There were no statistically significant differences in nicotinism and alcohol dependence syndrome frequency between both groups. CONCLUSIONS Based on each group inclusion criteria, a lower mortality rate in the control group indicates a crucial role of the therapeutic window in cerebral stroke treatment. Analysis of reasons for delay points out that efficient prophylaxis is the education of patients with stroke risk factors and their families.

Abstract
Stroke is a leading cause of mortality and morbidity with a paucity of effective pharmacological treatments. We have previously identified insulin-regulated aminopeptidase (IRAP) as a potential target for the development of a new class of drugs for the treatment of stroke, as global deletion of this gene in mice significantly protected against ischemic damage. In the current study, we demonstrate that small molecular weight IRAP inhibitors reduce infarct volume and improve neurological outcome in a hypertensive animal model of ischemic stroke. The effects of two structurally distinct IRAP inhibitors (HFI419 or SJM164) were investigated in a model of stroke where the middle cerebral artery was transiently occluded with endothelin-1 in the conscious spontaneously hypertensive rat. IRAP inhibitor was administered into the lateral ventricle at 2 or 6 h after stroke, with subsequent doses delivered at 24, 48 and 70 h post-stroke. Functional outcomes were assessed prior to drug treatment, and on day 1 and 3 post-stroke. Histological analyses and neuroinflammatory cytokine profiling were conducted at 72 and 24 h post-stroke respectively. IRAP inhibitor treatment following stroke significantly reduced infarct volume and improved neurological and motor deficits. These protective effects were maintained even when the therapeutic window was extended to 6 h. Examination of the cellular architecture at 72 h post-stroke demonstrated that IRAP expression was upregulated in CD11b positive cells and activated astrocytes. Furthermore, IRAP inhibitor treatment significantly increased gene expression for interleukin 6 and C-C motif chemokine ligand 2 in the ischemic core. This study provides proof-of-principle that selective inhibition of IRAP activity with two structurally distinct IRAP inhibitors reduces infarct volume and improves functional outcome even when the first dose is administered 6 h post-stroke. This is the first direct evidence that IRAP inhibitors are a class of drug with potential use in the treatment of ischemic stroke.

Abstract
To investigate the association between the Emergency Medical Service dispatcher's initial stroke triage and prehospital stroke management, primary admission to hospitals offering revascularization treatment, prehospital time delay, and rate of acute revascularization. In an observational cohort study, patients with acute ischemic stroke (AIS) in Denmark (2017-2018) were included if the emergency call to the Emergency Medical Dispatch Center (EMDC) was made within three hours after symptom onset. Among 3546 included AIS patients, the EMS dispatcher identified 74.6% (95% confidence interval (CI) 73.1-76.0) correctly as stroke. EMS dispatcher stroke recognition was associated with a higher rate of primary admission to a hospital offering revascularization treatment (85.8 versus 74.5%); producing an adjusted risk difference (RD) of 11.1% (95% CI 7.8; 14.3) and a higher rate of revascularization treatment (49.6 versus 41.6%) with an adjusted RD of 8.4% (95% CI 4.6; 12.2). We adjusted for sex, age, previous stroke or transient ischemic attack, and stroke severity. EMDC stroke recognition was associated with shorter prehospital delay. For all AIS patients, the adjusted difference was - 33.2 min (95% CI - 44.4; - 22.0). Among patients receiving acute revascularization treatment (n = 1687), the adjusted difference was -12.6 min (95% CI - 18.9; - 6.3). Stroke recognition by the EMS dispatcher was associated with a higher probability of primary admission to a hospital offering acute stroke treatment, and subsequently with a higher rate of acute revascularization treatment, and with an overall reduction in prehospital delay.

Trends in the neurological emergency room, focusing on persons with seizures. Eur J Neurol 2023; 30:3008-3015.

Abstract
BACKGROUND AND PURPOSE Previous studies in neurological emergency rooms (nERs) have reported many non-acute, self-presenting patients, patients with delayed presentation of stroke, and frequent visits of persons with seizures (PWS). The aim of this study was to evaluate trends during the last decade, with special focus on PWS. METHODS We retrospectively analyzed patients who presented to our specialized nER during the course of 5 months in 2017 and 2019, and included information on admission/referral, hospitalization, discharge diagnosis, and diagnostic tests/treatment in the nER. RESULTS A total of 2791 patients (46.6% male, mean age 57 ± 21 years) were included. The most common diagnoses were cerebrovascular events (26.3%), headache (14.1%), and seizures (10.5%). Most patients presented with symptoms lasting >48 h (41.3%). The PWS group included the largest proportion of patients presenting within 4.5 h of symptom onset (171/293, 58.4%), whereas only 37.1% of stroke patients presented within this time frame (273/735). Self-presentation was the most common admission pathway (31.1%), followed by emergency service referral (30.4%, including the majority of PWS: 197/293, 67.2%). Despite known diagnosis of epilepsy in 49.2%, PWS more often underwent accessory diagnostic testing including cerebral imaging, compared to the overall cohort (accessory diagnostics 93.9% vs. 85.4%; cerebral imaging 70.1% vs. 64.1%). Electroencephalography in the nER was only performed in 20/111 patients (18.0%) with a first seizure. Nearly half of the patients (46.7%) were discharged home after nER work-up, including most self-presenters (632/869, 72.7%) and headache patients (377/393, 88.3%), as well as 37.2% (109/293) of PWS. CONCLUSION After 10 years, nER overuse remains a problem. Stroke patients still do not present early enough, whereas PWS, even those with known epilepsy, often seek acute and extensive assessment, indicating gaps in pre-hospital management and possible over-assessment.

Abstract
Stroke is characterized by high morbidity, high mortality and high disability rate, which is a major health problem worldwide. However, most community-based studies report a lack of public knowledge related to stroke. The aim of this study is to investigate stroke-related knowledge and prevention practices among stroke patients in Taizhou, China. A face-to-face survey was conducted and questionnaires were completed by 156 S patients from June 27 to August 30, 2022. A generalized linear model was applied to explore the factors influencing prevention practices. Among the total participants, 36.5% and 40.4% of them had good knowledge of the stroke-related warning signs and risk factors, respectively. Participants who had good stroke prevention practices accounted for 57.7%. The higher score of stroke-related knowledge among inpatients, the better their prevention practices (B = 0.16, 95 %CI: 0.05 ∼ 0.28). In addition, those with age ≥ 60 (B = 1.20, 95 %CI: 0.42 ∼ 1.97), females (B = 0.93, 95 %CI: 0.24 ∼ 1.61), having physical activities (B = 1.01, 95 %CI: 0.33 ∼ 1.68), or without underlying diseases (B = -1.67, 95 %CI:-2.42 ∼ -0.92) were also related with prevention practices. In general, this survey indicated that the stroke-related knowledge and prevention practices of participants were not good enough. Stroke related knowledge, age, sex, physical activity, and underlying disease were significant factors related to stroke prevention practices. These findings suggest the need to focus on stroke health education for stroke patients.

Abstract
Background Until recently, public education campaigns aimed at improving help-seeking behavior by acute stroke patients have achieved only limited or even no effects. Better understanding of psychological factors determining help-seeking behavior may be relevant in the design of more effective future campaigns. Methods In this prospective, cross-sectional study, we interviewed 669 acute stroke patients within 72 h after hospital admission. The primary endpoint was the effect of psychological factors on the decision to call emergency medical services (EMS). Secondary endpoints were the effects of such factors on treatment rates and clinical improvement (difference between modified Rankin scale (MRS) scores at admission and at discharge). Results Only 48.7% of the study population called the EMS. Multivariate logistic and linear regression analyses revealed that perception of unimpaired performance of activities of daily living (ADL) was the only psychological factor that predicted EMS use and outcomes. Thus, patients who perceived only minor impairment in performing ADL were less likely to use EMS (odds ratio, 0.54 [95% confidence interval, 0.38-0.76]; p = 0.001), had lower treatment rates, and had less improvement in MRS scores (b = 0.40, p = 0.004). Additional serial mediation analyses involving ischemic stroke patients showed that perception of low impairment in ADL decreased the likelihood of EMS notification, thereby increasing prehospital delays, leading to reduced thrombolysis rates and, finally, to reduced clinical improvement. Conclusion Perception of unimpaired performance of ADL is a crucial barrier to appropriate help-seeking behavior after acute stroke, leading to undertreatment and less improvement in clinical symptoms. Thus, beyond improving the public's knowledge of stroke symptoms, future public education campaigns should focus on the need for calling the EMS in case of stroke symptoms even if daily activities do not seem to be severely impaired.

Abstract
INTRODUCTION General population proper knowledge about stroke can improve stroke outcomes. We aimed to assess the awareness levels of laypeople regarding stroke recognition, reaction, risk factors, and adequate general knowledge (correct answers for those three questions) of stroke. METHODS Cross-sectional survey-based study enrolling community population from 12 cities of Brazil's Northeast. The volunteers were verbally exposed to a typical case of stroke and then responded to an open-ended semi-structured questionnaire to evaluate their stroke knowledge. RESULTS A total of 1475 subjects enrolled in this study (52.6% of women, mean±SD 36.2±15.3 years-old, 13.0±4.4 years of formal schooling). 1220/1475 (82.7%) recognized the situation as a stroke; 1148/1475 (77.8%) would react to it by taking the patient to the emergency department or calling for emergency medical assistance; 844/1475 (57.2%) knew at least one risk factor; and 190/1475 (12.9%) stated that symptoms could be reversed if the patient was treated "as soon as possible". Adequate general knowledge was found in 622/1475 (42,2%) of participants. Notably, among those who recognized the stroke, 19.9% (243/1220) would not react appropriately to it. The multivariate analysis showed that factors independently related to stroke recognition were female sex, higher education levels, private health insurance and previous experience with a similar situation. Adequate general knowledge was associated with longer school years and health insurance. CONCLUSIONS The frequency of stroke recognition and appropriate reaction were acceptable, however the general knowledge, knowledge of risk factors and notion that stroke treatment is time-sensitive were insufficient. Addressing the recognition-reaction gap requires targeted campaigns focusing on stroke treatment awareness.

Abstract
INTRODUCTION Stroke is a time-critical condition and one of the leading causes of mortality and disability worldwide. To decrease mortality and improve patient outcome by improving access to optimal treatment, there is an emerging need to improve the accuracy of the methods used to identify and characterise stroke in prehospital settings and emergency departments (EDs). This might be accomplished by developing computerised decision support systems (CDSSs) that are based on artificial intelligence (AI) and potential new data sources such as vital signs, biomarkers and image and video analysis. This scoping review aims to summarise literature on existing methods for early characterisation of stroke by using AI. METHODS AND ANALYSIS The review will be performed with respect to the Arksey and O'Malley's model. Peer-reviewed articles about AI-based CDSSs for the characterisation of stroke or new potential data sources for stroke CDSSs, published between January 1995 and April 2023 and written in English, will be included. Studies reporting methods that depend on mobile CT scanning or with no focus on prehospital or ED care will be excluded. Screening will be done in two steps: title and abstract screening followed by full-text screening. Two reviewers will perform the screening process independently, and a third reviewer will be involved in case of disagreement. Final decision will be made based on majority vote. Results will be reported using a descriptive summary and thematic analysis. ETHICS AND DISSEMINATION The methodology used in the protocol is based on information publicly available and does not need ethical approval. The results from the review will be submitted for publication in a peer-reviewed journal. The findings will be shared at relevant national and international conferences and meetings in the field of digital health and neurology.

The PRESTO study: awareness of stroke symptoms and time from onset to intervention. Neurol Sci 2023; 44:229-236. [PMID: 36190685 DOI: 10.1007/s10072-022-06399-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2022] [Accepted: 08/11/2022] [Indexed: 11/05/2022]
Abstract
Timely access to medical assistance is the first crucial step to improving clinical outcomes of stroke patients. Many educational campaigns have been organized with the purpose of making people aware of what a stroke is and what is necessary to do after its clinical onset. The PRESTO campaign was organized in Genoa (Italy) to spread easy messages regarding the management of the acute phase of stroke. Educational material was disseminated to educate people to call the emergency medical services as soon as symptoms appear. Data collected were analyzed in three different phases of the campaign: before the beginning, during, and after the end. We enrolled 1,132 patients with ischemic stroke admitted to hospital within 24 hours of symptoms onset. Our data showed a mild reduction in onset-to-door time (24 minutes) during the months following the end of the campaign and a slight increase in number of patients who arrived at hospitals, in particular with milder symptoms and transient ischemic attack, as opposed to the same period before the campaign. Interestingly, in the months after the end of the campaign, we observed a slight reduction of the percentage of patients who accessed hospitals after 4.5 hours from symptoms onset. In conclusion, our results may suggest that an informative campaign can be successful in making people rapidly aware of stroke onset, with the consequent rapid access to hospitals. Considering the changing of way of access to information, we think that an extensive multimedia campaign should be evaluated in the next future.

Abstract
Prehospital delay after stroke symptom onset is a primary barrier to eligibility for reperfusion therapies. Decision delay is an understudied contributor to prehospital delay. We aimed to explore decision delay as a component of prehospital delay. For this correlational study, 170 Thai acute stroke patients were interviewed to explore their treatment-seeking decision factors: prior stroke knowledge, onset context, and cognitive, emotional, and behavioral factors. Participants' mean age was 61.2 years, and 46% were women. Median decision delay and prehospital delay times were 120 and 372 minutes. Decision delay represented 49% of prehospital delays. Factors shortening decision delay were atrial fibrillation, prior stroke knowledge, perceived cause of symptoms as stroke, perceived severity of symptoms, and advice from bystanders to seek treatment. In contrast, seeking support from others and self-treatment affected prolonged decision delay. Shortening decision delay, often under the patient or bystander control, can reduce overall prehospital delay.

Abstract
Background Early hospital presentation is critical in the management of acute ischemic stroke. The effectiveness of stroke treatment is highly dependent on the amount of time lapsed between onset of symptoms and treatment. This study was aimed to identify the factors associated with prehospital delay in patients with acute stroke. Material and Methods A cross-sectional descriptive study was conducted in Sri Ramachandra University Hospital, India. A total of 210 patients hospitalized in the stroke unit were included. Patients' data were obtained by interviewing the patient and/or accompanying family member and by reviewing their medical records using a standard questionnaire. Associations were determined between prehospital delay (≥4.5 h) and variables of interest by using univariate and multivariate logistic regression analyses. Results The prehospital delay was observed in 154 patients (73.3%) and the median prehospital delay was 11.30 h. The following are the factors significantly (P < 0.05) attributed for the delay in presenting to the hospital: contextual factors like using public transport (bus), taxi, time of onset of symptoms, 7 pm-3 am; family history of stroke, perceived cognitive and behavioral factors like, wishing or praying for the symptoms to subside on its own, hesitation to travel due to long distance, delay in arranging transport, and arranging money for admission and wasting time by shopping for general practitioners, nursing homes, and hospitals. The presence of stroke symptom, headache, significantly decreased the prehospital delay. Conclusions Prehospital delay is high in South India and influenced by clinical, contextual, and cognitive/behavioral factors.

Abstract
BACKGROUND Hospital arrival time after acute ischemic stroke onset is the major factor limiting the eligibility of patients to receive intravenous thrombolysis. Shortening the prehospital delay is crucial to reducing morbidity and mortality for stroke patients. The study was conducted to investigate the factors that influence hospital arrival time after acute stroke onset in the Lebanese population and to assess the effect of the prehospital phase on patients' prognosis at discharge. METHOD A prospective cross-sectional study was performed in eleven hospitals from April to July 2021 including 100 patients having stroke symptoms or transient ischemic attack (TIA). Two questionnaires were used to collect data addressing patient management in the pre-hospital phase and the in-hospital phase. Descriptive and bivariate analyses were done to evaluate the potential associations between prognosis, pre-hospital characteristics, and other factors. RESULTS The patients' mean age was 70.36 ± 12.25 years, 43 (53.8%) of them were females, and 79 (85%) arrived within 3 hours after symptoms onset. Diabetic patients had a significant delay in hospital arrival compared with non-diabetics (27.0%vs.7.1%, p-value = 0.009). Moreover, 37 (75.5%) of school-level education patients arrived early at the hospital compared to 7 (100%) of university-level education (p-value = 0.009). The modified Rankin Scale (mRS) at discharge in patients with hemorrhagic stroke (10 (90%)) was worse than that in patients with ischemic stroke (38 (80%)) or TIA (3 (15%)) (p-value< 0.001). CONCLUSION The study findings make it imperative to raise awareness about stroke symptoms among the Lebanese population. Emergency Medical Services should be utilized appropriately in the transportation of stroke patients to achieve optimal patient outcomes.

Kynurenine/Aryl Hydrocarbon Receptor Modulates Mitochondria-Mediated Oxidative Stress and Neuronal Apoptosis in Experimental Intracerebral Hemorrhage. Antioxid Redox Signal 2022; 37:1111-1129. [PMID: 35481813 PMCID: PMC9784632 DOI: 10.1089/ars.2021.0215] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/13/2021] [Revised: 04/14/2022] [Accepted: 04/16/2022] [Indexed: 12/30/2022]
Abstract
Aims: Oxidative stress and neuronal apoptosis play crucial roles in the pathological processes of secondary injury after intracerebral hemorrhage (ICH). Aryl hydrocarbon receptor (AHR), together with its endogenous ligand kynurenine, is known to mediate free radical accumulation and neuronal excitotoxicity in central nervous systems. Herein, we investigate the pathological roles of kynurenine/AHR after ICH. Results: Endogenous AHR knockout alleviated reactive oxygen species accumulation and neuronal apoptosis in ipsilateral hemisphere at 48 h after ICH in mice. The ICH insult resulted in an increase of total and nucleus AHR protein levels and AHR transcriptional activity. Inhibition of AHR provided both short- and long- term neurological benefits by attenuating mitochondria-mediated oxidative stress and neuronal apoptosis after ICH in mice. RhoA-Bax signaling activated mitochondrial death pathway and participated in deleterious actions of AHR. Finally, we reported that exogenous kynurenine aggravated AHR activation and mediated the brain mentioned earlier. Male animals were used in the experiments. Innovation: We show for the first time that kynurenine/AHR mediates mitochondria death and free radical accumulation, at least partially via the RhoA/Bax signaling pathway. Pharmacological antagonists of AHR and kynurenine may ameliorate neurobehavioral function and improve the prognosis of patients with ICH. Conclusion: Kynurenine/AHR may serve as a potential therapeutic target to attenuate mitochondria-mediated oxidative stress and neuronal cells impairment in patients with ICH. Antioxid.

Time to Endovascular Reperfusion and Outcome in Acute Ischemic Stroke : A Nationwide Prospective Registry in China. Clin Neuroradiol 2022; 32:997-1009. [PMID: 35622100 DOI: 10.1007/s00062-022-01178-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2022] [Accepted: 04/25/2022] [Indexed: 12/15/2022]
Abstract
PURPOSE The benefit of endovascular reperfusion therapy for acute ischemic stroke is highly time-dependent but the relation of delays in workflow with outcomes and the key determinants of delays remain uncertain. This study aimed to evaluate the association between faster endovascular therapy and outcomes in a Chinese population with acute ischemic stroke. METHODS Patients treated with endovascular therapy within 7 h due to anterior large vessel occlusion were enrolled in the ANGEL-ACT registry. Time intervals from hospital arrival to arterial puncture (door-to-puncture), hospital arrival to reperfusion (door-to-reperfusion) and puncture-to-reperfusion were recorded. The outcomes included modified Rankin Scale (mRS) scores 0-1, 0-2, mortality at 3 months, substantial reperfusion, and symptomatic intracranial hemorrhage (sICH). RESULTS Of 932 patients receiving endovascular therapy (mean age 65.1 years, 60.1% male), the median door-to-puncture, door-to-reperfusion, and puncture-to-perfusion times were 110min (interquartile range, IQR 72-155min), 200min (IQR, 149-260min), and 76min (IQR, 50-118min). Of the patients 87.4% achieved substantial reperfusion and 9.6% had sICH. The mRS 0-1, 0-2, and mortality at 3 months were 39.8%, 43.2%, and 16.4%. Faster door-to-reperfusion and puncture-to-reperfusion were associated with higher likelihood of mRS 0-1, mRS 0-2, and lower rate of sICH. There was a trend of improved mRS, lower mortality, and fewer ICH with shorter door-to-puncture time; however, most differences were not statistically significant. CONCLUSION Among patients with acute ischemic stroke in routine clinical practice, shorter time to reperfusion was associated with better outcome after endovascular therapy. Standardized workflows and training in endovascular treatment techniques should be promoted nationally to reduce in-hospital delays.

Abstract
Objectives To investigate the association between pre-hospital 12-lead electrocardiogram (PHECG) use in patients presenting to emergency medical services (EMS) with acute stroke, and clinical outcomes and system delays. Methods Multi-centre linked cohort study. Patients with verified acute stroke admitted to hospital via EMS were identified through routinely collected hospital data and linked to EMS clinical records via EMS unique identifiers. Ordinal and logistic regression analyses were undertaken to analyse the relationship between having a PHECG and modified Rankin Scale (mRS); hospital mortality; pre-hospital time intervals; door-to-scan and door-to-needle times; and rates of thrombolysis. Results Of 1161 eligible patients admitted between 29 December 2013 and 30 January 2017, PHECG was performed in 558 (48%). PHECG was associated with an increase in mRS (adjusted odds ratio [aOR] 1.30, 95% confidence interval [CI] 1.01-1.66, p = 0.04) and hospital mortality (aOR 1.83, 95% CI 1.26-2.67, p = 0.002). There was no association between PHECG and administration of thrombolytic treatment (aOR 1.06, 95% CI 0.75-1.52, p = 0.73). Patients who had PHECG recorded spent longer under the care of EMS (median 49 vs 43 minutes, p = 0.006). No difference in times to receiving brain scan (median 28 with PHECG vs 29 minutes no PHECG, p = 0.32) or thrombolysis (median 46 vs 48 minutes, p = 0.37) were observed. Conclusion The PHECG was associated with worse outcomes and longer delays in patients with acute ischaemic stroke.

Abstract
BACKGROUND AND OBJECTIVES Early access to hospital for diagnosis and treatment is strongly recommended for patients with acute stroke. Unfortunately, prehospital delay frequently occurs. The aim of the current study was to gain in-depth insight into patient experience and behavior in the prehospital phase of a stroke. METHODS We conducted qualitative interviews with a purposive sample of 11 patients and six witnesses within four weeks post stroke. The interviews were audio recorded, transcribed, and analyzed utilizing Systematic Text Condensation. RESULTS The material was classified according to two main categories each containing three subgroups. The first category contained the diversity of sudden changes that all participants noticed. The subgroups were confusing functional changes, distinct bodily changes and witnesses' observations of abnormal behavior or signs. The second category was delaying and facilitating factors. To trivialize or deny stroke symptoms, or having a high threshold for contacting emergency services, led to time delay. Factors facilitating early contact were severe stroke symptoms, awareness of the consequences of stroke or a witness standing by when the stroke occurred. CONCLUSIONS Prehospital delays involved interrelated elements: (1) Difficulties in recognition of a stroke when symptoms were mild, odd and/or puzzling; (2) Recognition of a stroke or need for medical assistance were facilitated by interaction/communication; (3) High threshold for calling emergency medical services, except when symptoms were severe. The findings may be helpful in planning future public stroke campaigns and in education and training programs for health personnel.

Pre-Hospital Delay in Acute Ischemic Stroke Care: Current Findings and Future Perspectives in a Tertiary Stroke Center from Romania-A Cross-Sectional Study. MEDICINA (KAUNAS, LITHUANIA) 2022; 58:1003. [PMID: 36013470 PMCID: PMC9415394 DOI: 10.3390/medicina58081003] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/30/2022] [Revised: 07/22/2022] [Accepted: 07/23/2022] [Indexed: 12/16/2022]
Abstract
Background and objectives: The time interval between stroke onset and hospital arrival is a major barrier for reperfusion therapies in acute ischemic stroke and usually accounts for most of the onset-to-treatment delay. The present study aimed to analyze the pre-hospital delays for patients with acute ischemic stroke admitted to a tertiary stroke center in Romania and to identify the factors associated with a late hospital arrival. Material and methods: The study population consisted of 770 patients hospitalized with the diagnosis of acute ischemic stroke in the University Emergency Hospital Bucharest during a 6-month period, between 1 January and 30 June 2018. Data regarding pre-hospital delays were prospectively collected and analyzed together with the demographic and clinical characteristics of the patients. Results: In total, 31.6% of patients arrived at the hospital within 4.5 h from stroke onset and 4.4% in time intervals between 4.5 and 6 h from the onset, and 28.7% of the patients reached the hospital more than 24 h after onset of symptoms. Transport to hospital by own means was the only factor positively associated with arrival to hospital > 4.5 h from stroke onset and more than doubled the odds of late arrival. Factors negatively associated with hospital arrival > 4.5 h after stroke onset were prior diagnosis of atrial fibrillation, initial National Institute of Health Stroke Scale (NIHSS) score ≥ 16 points, presence of hemianopsia, facial palsy and sensory disturbance. Factors increasing the odds of hospital arrival after 24 h from stroke onset were living alone and living in rural areas. Conclusions: Almost one in three ischemic stroke patients presenting to our center reaches hospital more than 24 h after onset of symptoms. These findings highlight the need for urgent measures to improve not only stroke awareness but also pre-hospital protocols in order to provide timely and appropriate care for our stroke patients.

J Stroke Cerebrovasc Dis 2022; 31:106614. [PMID: 35858514 DOI: 10.1016/j.jstrokecerebrovasdis.2022.106614] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2022] [Revised: 06/05/2022] [Accepted: 06/20/2022] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND Cognitive impairment is common and problematic post-stroke, yet vital information to understand early cognitive recovery is lacking. To examine early cognitive recovery, it is first necessary to establish the feasibility of repeat cognitive assessment during the acute post-stroke phase. OBJECTIVE To determine if serial computerised testing is feasible for cognitive assessment in an acute post-stroke phase, measured by assessment completion rates. METHOD An observational cohort study recruited consecutive stroke patients admitted to an acute stroke unit within 48 hours of onset. Daily assessment with the Cambridge Neuropsychological Test Automated Battery (CANTAB) was performed for seven days, and single Montreal Cognitive Assessment (MoCA). RESULTS Seventy-one participants were recruited, mean age 74 years, with 67 completing daily testing. Participants had predominantly mild (85%; NIHSS ≤6), ischemic (90%) stroke, 32% demonstrated clinical delirium. The first day of testing, 76% of participants completed CANTAB batteries. Eighty-seven percent of participants completed MoCA a mean of 3.4 days post-stroke. The proportion of CANTAB batteries completed improved significantly from day 2 to day 3 post-stroke with test completion rates stabilizing ≥ 92% by day 4. Participants with incomplete CANTAB were older, with persisting delirium, and longer stay in acute care. CONCLUSION Serial computerised cognitive assessments are feasible the first week post-stroke and provide a novel approach to measuring cognitive change for both clinical and research purposes. Maximum completion rates by day four have clinical implications for optimal timing of cognitive testing.

ENVIRONMENTAL RESEARCH 2022; 207:112229. [PMID: 34699760 PMCID: PMC8810591 DOI: 10.1016/j.envres.2021.112229] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/10/2021] [Revised: 10/08/2021] [Accepted: 10/15/2021] [Indexed: 05/03/2023]
Abstract
BACKGROUND While evidence suggests that daily ambient temperature exposure influences stroke risk, little is known about the potential triggering role of ultra short-term temperature. METHODS We examined the association between hourly temperature and ischemic and hemorrhagic stroke, separately, and identified any relevant lags of exposure among adult New York State residents from 2000 to 2015. Cases were identified via ICD-9 codes from the New York Department of Health Statewide Planning and Reearch Cooperative System. We estimated ambient temperature up to 36 h prior to estimated stroke onset based on patient residential ZIP Code. We applied a time-stratified case-crossover study design; control periods were matched to case periods by year, month, day of week, and hour of day. Additionally, we assessed effect modification by leading stroke risk factors hypertension and atrial fibrillation. RESULTS We observed 578,181 ischemic and 164,755 hemorrhagic strokes. Among ischemic and hemorrhagic strokes respectively, the mean (standard deviation; SD) patient age was 71.8 (14.6) and 66.8 (17.4) years, with 55% and 49% female. Temperature ranged from -29.5 °C to 39.2 °C, with mean (SD) 10.9 °C (10.3 °C). We found linear relationships for both stroke types. Higher temperature was associated with ischemic stroke over the 7 h following exposure; a 10 °C increase over 7 h was associated with 5.1% (95% Confidence Interval [CI]: 3.8, 6.4%) increase in hourly stroke rate. In contrast, temperature was negatively associated with hemorrhagic stroke over 5 h, with a 5-h cumulative association of -6.2% (95% CI: 8.6, -3.7%). We observed suggestive evidence of a larger association with hemorrhagic stroke among patients with hypertension and a smaller association with ischemic stroke among those with atrial fibrillation. CONCLUSION Hourly temperature was positively associated with ischemic stroke and negatively associated with hemorrhagic stroke. Our results suggest that ultra short-term weather influences stroke risk and hypertension may confer vulnerability.

Abstract
BACKGROUND In recent years, a series of initiatives have been launched to promote intravenous thrombolysis (IVT) and endovascular therapy (EVT) for acute ischaemic stroke (AIS) in China. We aimed to update the rates of IVT and EVT in China between 2019 and 2020 and to evaluate the current IVT and EVT according to hospital grades. METHODS Cross-sectional data on patients receiving IVT/EVT were derived from the Bigdata Observatory platform for Stroke of China (BOSC). The monthly number of discharged patients with a principal diagnosis of AIS was derived from the first pages of medical records of each hospital. The rates and information of IVT and EVT were analysed according to hospital grades. FINDINGS During this period, 938 tertiary hospitals and 786 secondary hospitals from 31 provinces continuously reported data to the BOSC. The overall IVT rate for AIS was 5·64%, and the EVT rate was 1·45%. The IVT rate in secondary hospitals was higher than that in tertiary hospitals (6·39% vs. 5·39%, P < 0·001), whereas the EVT rate in secondary hospitals was much lower than that in tertiary hospitals (0·29% vs. 1·84%, P < 0·001). Significant differences in demographic and clinical characteristics of patients receiving IVT/EVT were also shown between tertiary and secondary hospitals. INTERPRETATION The rates of IVT and EVT for AIS have greatly increased in China, but there is still a large gap compared with developed countries. Hospital inhomogeneity in IVT and EVT suggests the importance of developing a region-specific network for stroke treatment. FUNDING None.

Estimated number of eligible patients for mechanical thrombectomy based on NIHSS and population-based Brest stroke registry. Rev Neurol (Paris) 2022; 178:546-557. [PMID: 35181159 DOI: 10.1016/j.neurol.2021.11.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2021] [Revised: 10/28/2021] [Accepted: 11/08/2021] [Indexed: 11/24/2022]
Abstract
BACKGROUND Since 2015, mechanical thrombectomy (MT) is indicated as a treatment for patients with large vessel occlusion (LVO) at the acute phase of ischemic stroke. However, the number of stroke patients eligible for MT is poorly known. OBJECTIVE The objective of our study was to estimate the number of patients eligible for thrombectomy within the first 24hours of an ischemic stroke, based on the clinical National Institute of Health Stroke Scale (NIHSS). METHOD Our study concerned all ischemic strokes which occurred between January 2013 and December 2016 recorded in the population-based Brest Stroke Registry (BSR). Based on positive predictive value and negative predictive value from articles evaluating the performance of a defined NIHSS threshold to identify LVO, we first estimated the frequency of patients with LVO and then the frequency of patients eligible for MT depending on pre-stroke modified Rankin score (mRS). Our results were extrapolated to regions of metropolitan France. Two scenarios were considered: one called "stringent criteria" with mRS ≤1 and one called "real-life" criteria with mRS ≤2. RESULT We analyzed data from 2,025 ischemic strokes with symptom onset ≤24hours. No statistical difference between patient characteristics according to the time of hospital admission (≤6H vs. 6-24H) was observed. Based on NIHSS scores, between 23.90% and 44.20% of ischemic strokes admitted within the first six hours had LVO clinical characteristics. Among them, 14.53% to 26.87% met the ``stringent eligibility'' criteria for MT and 16.9 to 31.25% for ``real-life'' criteria. Eligible patients represented 6.32% to 11.70% of all ischemic strokes, irrespective of admission time. In France, 75 to 162 persons per million inhabitants per year were eligible for endovascular therapy, depending on including criteria. Based on activity levels recorded by the French Neuroradiology Society (SFNR) in 2018, the estimated needed increase in MT showed a heterogeneous pattern region-by-region, with the greatest need in Brittany, Pays de la Loire, and Corsica. CONCLUSION Based on NIHSS, our study provides coherent information concerning the estimated number of MT procedures to be performed in France: 4,877 to 10,494 ischemic strokes would be eligible each year in metropolitan France compared to the 6,596 thrombectomy procedures actually performed in 2018. Depending on the region, an estimated 10-20% to 90-100% increase in MT activity would be necessary to meet patient needs. These data suggest that there is still room for improvement in thrombectomy activity, particularly in certain regions of France, to allow equal access to MT to the entire French population.

Abstract
INTRODUCTION Stroke is one of the leading causes of death and disability worldwide. The ambulance service is often the first medical service to reach an acute stroke patient, and due to the time-critical nature of stroke, a time-critical assessment and rapid transport to a hyper acute stroke unit are essential. As stroke services have been centralised, different hospitals have implemented different pre-alert admission policies that may affect the on-scene time of the attending ambulance crew. The aim of this study is to investigate if the different pre-alert admission policies affect time on scene. METHOD The current study is a retrospective quantitative observational study using data routinely collected by North East Ambulance Service NHS Foundation Trust. The time on scene was divided into two variables; group one was a telephone pre-alert in which a telephone discussion with the receiving hospital is required before they accept admission of the patient. Group two was a radio-style pre-alert in which the attending clinician makes an autonomous decision on the receiving hospital and alerts them via a short radio message of the incoming patient. These times were then compared to identify if there was any difference between them. RESULTS Data on 927 patients over a three-month period, from October to December 2019, who had received the full stroke bundle of care, were within the thrombolysis window and recorded as a stroke by the attending clinician, were split into the variable groups and reported on. The mean time on scene for a telephone call pre-alert was 33 minutes and 19 seconds, with a standard deviation of 13 minutes and 8 seconds. The mean on-scene time for a radio pre-alert was 28 minutes and 24 seconds, with a standard deviation of 11 minutes and 51 seconds. CONCLUSION A pre-alert given via radio instead of via telephone is shown to have a mean time saving of 4 minutes and 55 seconds, representing an important decrease in time which could be beneficial to patients.

"Hesitating and Puzzling": The Experiences and Decision Process of Acute Ischemic Stroke Patients with Prehospital Delay after the Onset of Symptoms. Healthcare (Basel) 2021; 9:healthcare9081061.

Abstract
Despite campaigns to increase public awareness of stroke symptoms by advocating FAST (Face-Arms-Speech-Time), some stroke patients still show delays in the recognition of and response to stroke symptoms and miss the golden first 4.5 h to receive rt-PA (recombinant tissue plasminogen activator) treatment. The aim of this study was to explore how acute ischemic stroke patients with prehospital delay seek help and undergo the decision process before arriving at the hospital. A qualitative approach using a grounded theory was applied. There were 24 ischemic stroke patients recruited by purposive sampling. Our main findings were: “Hesitating and puzzling” was the core category to describe and guide the process of acute ischemic stroke patients with prehospital delay. During the process, “Awareness the sudden change of physical sensation and/or function” was the antecedent category. In the prehospital delay experience, the following five interaction categories were identified: (1) “Self-judgment and interpretation according to previous experience,” (2) “Puzzling and doubting—it may only be a minor problem,” (3) “Self-treatment or seeking medical attention nearby,” (4) “Unexpected symptoms getting worse” needing immediate advanced medical help and (5) “Rushing to ER with different transportation—self-alerting that serious disease is coming.” Eventually, the patients “Regret to delay seeking treatment and become a disable person.” The process of prehospital delay provides some hidden cues for patients to increase their knowledge about strokes. The study emphasizes the importance of educating community residents about identifying stroke symptoms, breaking the myth of folk therapy, and seeking medical attention immediately. These results will assist healthcare providers by offering references for designing patient-centric educational strategies for preventing stroke prehospital delay to improve the quality of stroke medical care.

Abstract
BACKGROUND In the current study we investigated the causes of pre-hospital delay as this can compromise the patient's chance to receive thrombolytic therapy and thus impact stroke outcome. METHODS We surveyed 254 patients regarding reasons for delayed and early arrival to hospital after acute ischemic stroke. The survey was performed over five months, spanning a period pre- and during COVID-19 (between December 7, 2019 and May 10, 2020). RESULTS A total of 71.2% of patients arrived beyond four hours of onset of ischemic stroke. The commonest cause for delay pre-Covid-19 was receiving treatment in a non-stroke hospital, while that during COVID-19 was fear of infection and lock down issues. Not realizing the urgency of the condition and stroke during sleep were common in both periods. Early arrival because of the patient's previous experience with stroke accounted for approximately 25% of cases in both periods. The effect of media was more evident during COVID-19, accounting for 47.7% of cases. CONCLUSION Pre-hospital delay secondary to misperception of the urgency of stroke and management in a non-stroke hospital reflect the lack of awareness among the public and medical staff. This concept is emphasized by early arrival secondary to previous experience with stroke and the pronounced effect of media in the time of COVID-19.

Abstract
OBJECTIVE To derive and characterize the performance of various metrics of emergency transport time in assessing for sociodemographic disparities in the setting of residential segregation. Secondarily to characterize racial disparities in emergency transport time of suspected stroke patients in Austin, Texas. DATA SOURCES We used a novel dataset of 2518 unique entries with detailed spatial and temporal information on all suspected stroke transports conducted by a public emergency medical service in Central Texas between 2010 and 2018. STUDY DESIGN We conducted one-way ANOVA tests with post-hoc pairwise t-tests to assess how mean hospital transport times varied by patient race. We also developed a spatially-independent metric of emergency transport urgency, the ratio of expected duration of self-transport to a hospital and the measured transport time by an ambulance. DATA COLLECTION/EXTRACTION We calculated ambulance arrival and destination times using sequential temporospatial coordinates. We excluded any entries in which patient race was not recorded. We also excluded entries in which ambulances' routes did not pass within 100 m of either the patient's location or the documented hospital destination. PRINCIPAL FINDINGS We found that mean transport time to a hospital was 2.5 min shorter for black patients compared to white patients. However, white patients' transport times to a hospital were found to be, on average, 4.1 min shorter than expected compared to 3.4 min shorter than expected for black patients. One-way ANOVA testing for the spatially-independent index of emergency transport urgency was not statistically significant, indicating that average transport time did not vary significantly across racial groups when accounting for variations in transport distance. CONCLUSIONS Using a novel transport urgency index, we demonstrate that these findings represent race-based variation in spatial distributions rather than racial bias in emergency medical transport. These results highlight the importance of closely examining spatial distributions when utilizing temporospatial data to investigate geographically-dependent research questions.

Abstract
BACKGROUND Reducing door-to-needle time (DNT) for intravenous thrombolysis in acute ischaemic stroke can lead to improved patient outcomes. Long-term reports on DNT trends in Australia are lacking in the setting of extension of the thrombolysis time window, addition of mechanical thrombectomy and increasing presentations. AIMS To examine 17-year trends of DNT and identify factors associated with improved DNT at a high-volume, metropolitan primary stroke centre. METHOD Retrospective study between 2003 and 2019 of all thrombolysis cases using departmental stroke database. Since most strategies were implemented from 2012 onwards, intervention period has been defined as period 2012-2019. Factors associated with DNT reduction were examined by regression modelling. RESULTS 15 strategies were identified including alterations to 'Code Stroke' processes. 1250 patients were thrombolysed, with 737 (58.8%) treated during the intervention period. The proportion of DNT ≤60- minutes rose from average of 22.5% during 2003-2012 to 63% during 2015-2018 and 71% in 2019. However, median DNT has only marginally improved from 58 to 51 minutes between 2015 and 2019. Faster DNT was independently associated with two modifiable workflow factors, 'Direct-to-CT' protocol (P < 0.001) and acute stroke nurse presence (P < 0.005). Over time, treated patients were older and less independent (P < 0.001), and the number of annual stroke admissions and 'Code Stroke' activations have risen by 4- and 10-fold to 748 and 1298 by 2019, respectively. CONCLUSIONS Targeted quality improvement initiatives are key to reducing thrombolysis treatment delays in the Australian metropolitan setting. Relative stagnation in DNT improvement is concerning and needs further investigation. This article is protected by copyright. All rights reserved.

Abstract
OBJECTIVES This study aimed to estimate prehospital delay and to identify the factors associated with the late arrival of patients with ischemic stroke at the Souss Massa Regional Hospital Center in Morocco. PATIENTS AND METHODS An observational, prospective, cross-sectional study was conducted from March 2019 to September 2019 in the Souss Massa regional hospital center, which is a public hospital structure. A questionnaire was administered to patients with ischemic stroke and to bystanders (family or others), while clinical and paraclinical data were collected from medical records. Univariate and multivariate logistic regression analyses were used to identify the factors associated with delayed arrival at emergency department. RESULTS A total of 197 patients and 197 bystanders who fulfilled the criteria for the study were included. The median time from symptom onset to hospital arrival was 6hours (IQR, 4-16). Multiple regression analysis showed that illiteracy (OR 38.58; CI95%: 3.40-437.27), waiting for symptoms to disappear (patient behavior) (OR 11.24; CI95%: 1.57-80.45), deciding to go directly to the hospital (patient behavior) (OR 0.07; CI95%: 0.01-0.57), bystander's knowledge that stroke is a disease requiring urgent care within a limited therapeutic window (OR 0.005; CI95%: 0.00-0.36), and direct admission without reference (OR 0.005; CI95%: 0.00-0.07), were independently associated with late arrival (>4.5hours) of patients with acute ischemic stroke. In addition, illiteracy (OR 24.62; CI95%: 4.37-138.69), vertigo and disturbance of balance or coordination (OR 0.14; CI95%: 0.03-0.73), the relative's knowledge that stroke is a disease requiring urgent care and within a limited therapeutic window (OR 0.03; CI95%: 0.00-0.22), calling for an ambulance (relative's behavior) (OR 0.16; CI95%: 0.03-0.80), distance between 50 and 100km (OR 10.16; CI95%: 1.16-89.33), and direct admission without reference (OR 0.03; CI95%: 0.00-0.14), were independently associated with late arrival (>6hours) of patients with acute ischemic stroke. CONCLUSION Patient behavior, bystander knowledge and direct admission to the competent hospital for stroke care are modifiable factors potentially useful for reducing onset-to-door time, and thereby increasing the implementation rates of acute stroke therapies.

[PMID: 34051450 DOI: 10.1016/j.jstrokecerebrovasdis.2021.105873] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2020] [Revised: 04/24/2021] [Accepted: 04/30/2021] [Indexed: 10/21/2022] Open
Abstract
OBJECTIVES To investigate the differences in clinical backgrounds, especially weekly variations of stroke occurrence, between hyper-acute ischemic stroke patients with and without regular employment (RE), as well as the impact of RE on outcome. MATERIALS AND METHODS Symptomatic ischemic stroke patients with ≤4.5 h from onset to door were enrolled. First, we divided patients into the RE and non-RE group to analyze differences in clinical characteristics, especially relation between weekly variations of stroke occurrence and RE. Second, we divided the same patients into those with and without favorable outcomes (modified Rankin Scale score of 0 to 2 at 3 months from stroke onset) to analyze the impact of RE on outcomes. RESULTS We screened 1,249 consecutive symptomatic ischemic stroke patients and included 377 patients (284 [75%] males; median age, 67 years). Of these patients, 248 (66%) were included in RE group. First, RE was independently associated with occurrence of stroke on Monday in reference to Sunday or a public holiday (OR 2.562, 95% CI 1.004-6.535, p = 0.049). Second, RE (OR 2.888 95% CI 1.378-6.050, p = 0.005) was a factor independently associated with a favorable outcome. CONCLUSIONS Patients with RE were more likely to have a hyper-acute ischemic stroke on Monday in reference to Sunday or a public holiday. However, RE before stroke onset appears to have a positive impact on outcome.

Abstract
BACKGROUND Prehospital delays are a major obstacle to timely reperfusion therapy in acute ischemic stroke. Stroke sign recognition, however, remains poor in the community. We present an analysis of repeated surveys to assess the impact of Face, Arm, Speech, Time (FAST) public awareness campaigns on stroke knowledge. METHODS Four cross-sectional surveys were conducted between July 2016 and January 2019 in the province of Quebec, Canada (n = 2,451). Knowledge of FAST stroke signs (face drooping, arm weakness and speech difficulties) was assessed with open-ended questions. A bilingual English/French FAST public awareness campaign preceded survey waves 1-3 and two campaigns preceded wave 4. We used multivariable ordinal regression models weighted for age and sex to assess FAST stroke sign knowledge. RESULTS We observed an overall significant improvement of 26% in FAST stroke sign knowledge between survey waves 1 and 4 (odds ratio [OR] = 1.26; 95% CI: 1.02, 1.55; p = 0.035). After the last campaign, however, 30.5% (95% CI: 27.5, 33.6) of people were still unable to name a single FAST sign. Factors associated with worse performance were male sex (OR = 0.68; 95% CI: 0.53, 0.86; p = 0.002) and retirement (OR = 0.54; 95% CI: 0.35, 0.83; p = 0.005). People with lower household income and education had a tendency towards worse stroke sign knowledge and were significantly less aware of the FAST campaigns. CONCLUSIONS Knowledge of FAST stroke signs in the general population improved after multiple public awareness campaigns, although it remained low overall. Future FAST campaigns should especially target men, retired people and individuals with a lower socioeconomic status.

Abstract
Background: Prior research suggests that initial aphasia severity, lesion size, and lesion location are the most salient factors in predicting recovery outcomes. While these factors provide important prognostic information, information that is individualized and readily available to clinicians is limited. Deficits in naming are common to all aphasia types and are routinely targeted in aphasia assessment and treatment, with cues provided to facilitate lexical retrieval.Objectives: In this study, we examine aphasia recovery factors that are readily available to clinicians, examining whether a person's ability to improve naming with cues, indicating "stimulability," will be predictive of future word retrieval.Methods: Ten participants with aphasia following a left-hemisphere stroke participated in initial assessment, seven of whom met criteria for longitudinal assessment. Stroke and early clinical recovery data were collected for all participants. At four timepoints over one year we evaluated longitudinal participants' naming ability and measured the proportion of successful lexical retrieval with the presentation of phonemic, feature, and sentence cues.Results: For all participants, multiple descriptive factors regarding recovery, including lesion information, information from the acute inpatient timeframe, and communication opportunities, were examined. For individuals followed longitudinally, naming stimulability did not consistently predict naming accuracy at the subsequent assessment timepoint. Individuals' attempts at naming emerged as a metric related to future naming performance warranting further evaluation.Conclusions: Multiple factors related to recovery must be considered when providing prognostic information. Naming stimulability and attempts at naming provide some information regarding future performance, but are not consistently reliable across timepoints.

Abstract
BACKGROUND Hospital arrival via ambulance influences treatment of acute stroke. We aimed to determine the factors associated with use of ambulance and access to evidence-based care among patients with stroke. METHODS Patients with first-ever strokes from the Australian Stroke Clinical Registry (2010-2013) were linked with administrative data (emergency, hospital admissions). Multilevel, multivariable regression models were used to determine patient, clinical and system factors associated with arrival by ambulance. RESULTS Among the 6,262 patients with first-ever stroke, 4,737 (76%) arrived by ambulance (52% male; 80% ischaemic). Patients who were older, frailer, with comorbidities or were unable to walk on admission (stroke severity) were more likely to arrive by ambulance to hospital. Compared to those using other means of transport, those who used ambulances arrived to hospital sooner after stroke onset (minutes, 124 vs 397) and were more likely to receive reperfusion therapy (adjusted odds ratio, 1.57, 95% CI: 1.09, 2.27). CONCLUSION Patients with stroke who use ambulances arrived faster and were more likely to receive reperfusion therapy compared to those using personal transport. Further public education about using ambulance services at all times, instead of personal transport when stroke is suspected is needed to optimise access to time critical care.

Abstract
PurposeThe substantial increase in non-communicable diseases (NCDs) is considered a major threat to developing countries. According to various international organizations and researchers, Kerala is reputed to have the best health system in India. However, many economists and health-care experts have discussed the risks embedded in the asymmetrical developmental pattern of the state, considering its high health-care and human development index and low economic growth. This study, a scoping review, aims to explore four major health economic issues related to the Kerala health system.Design/methodology/approachA systematic review of the literature was performed using PRISMA to facilitate selection, sampling and analysis. Qualitative data were collected for thematic content analysis.FindingsChronic diseases in a significant proportion of the population, low compliance with emergency medical systems, high health-care costs and poor health insurance coverage were observed in the Kerala community.Research limitations/implicationsThe present study was undertaken to determine the scope for future research on Kerala's health system. Based on the study findings, a structured health economic survey is being conducted and is scheduled to be completed by 2021. In addition, the scope for future research on Kerala's health system includes: (1) research on pathways to address root causes of NCDs in the state, (2) determine socio-economic and health system factors that shape health-seeking behavior of the Kerala community, (3) evaluation of regional differences in health system performance within the state, (4) causes of high out-of-pocket expenditure within the state.Originality/valueGiven the internationally recognized standard of Kerala's vital statistics and health system, this review paper highlights some of the challenges encountered to elicit future research that contributes to the continuous development of health systems in Kerala.

Abstract
Objectives Stroke patients should be treated as soon as possible since the benefit of reperfusion therapies is highly time‐dependent. The proportion of patients eligible for reperfusion therapy is still limited, as many patients do not immediately alarm healthcare providers. The choice of healthcare system entrance influences the time of arrival in the hospital. Therefore, we assessed differences in these choices to obtain insight for strategies to reduce time delays in acute stroke patients. Materials and Methods Patients with suspected acute stroke admitted to the participating hospitals received a questionnaire. We assessed differences between patients who initially alarmed the general practitioner (GP) and patients who directly alarmed the emergency medical services (EMS). Additionally, we assessed regional differences and patient trajectories after medical help was sought. Results We included 163 patients. Most patients alarmed the GP as primary healthcare provider (n = 104; 64%), and median onset‐to‐door times were longer in these patients (466 minutes [IQR 149–1586]) compared to patients directly alarming the EMS (n = 59; 36%) (90 minutes [IQR 45–286]). This was even more pronounced in less densely populated areas. Patients who alarmed the GP first, more often had patient delay >15 minutes, hesitated to burden healthcare providers and underestimated symptomatology. Conclusions Our results showed that patients who alarmed the GP first instead of the EMS differed in several factors that are potentially modifiable. Strategies to achieve reduction of vital prehospital time delays and to improve patient outcome are optimizing public awareness campaigns and GP triage along with adjusting current guidelines by enabling and focusing on immediate involvement of the EMS once acute stroke is suspected.

Abstract
One major aim of preclinical intracerebral hemorrhage (ICH) research is to develop and test potential neuroprotectants. Published guidelines for experimental design and reporting stress the importance of clearly and completely reporting results and methodological details to ensure reproducibility and maximize information availability. The current review has two objectives: first, to characterize current ICH neuroprotection research and, second, to analyze aspects of translational design in preclinical ICH studies. Translational design is the adoption and reporting of experimental design characteristics that are thought to be clinically relevant and critical to reproducibility in animal studies (e.g., conducting and reporting experiments according to the STAIR and ARRIVE guidelines, respectively). Given that ICH has no current neuroprotective treatments and an ongoing reproducibility crisis in preclinical research, translational design should be considered by investigators. We conducted a systematic review of ICH research from 2015 to 2019 using the PubMed database. Our search returned 281 published manuscripts studying putative neuroprotectants in animal models. Contemporary ICH research predominantly uses young, healthy male rodents. The collagenase model is the most commonly used. Reporting of group sizes, blinding, and randomization are almost unanimous, but group size calculations, mortality and exclusion criteria, and animal model characteristics are infrequently reported. Overall, current ICH neuroprotection research somewhat aligns with experimental design and reporting guidelines. However, there are areas for improvement. Because failure to consider translational design is associated with inflation of effect sizes (and possibly hindered reproducibility), we suggest that researchers, editors, and publishers collaboratively consider enhanced adherence to published guidelines.

Abstract
Stroke is a complex, time-sensitive, medical emergency that requires well functioning systems of care to optimise treatment and improve patient outcomes. Education and training campaigns are needed to improve both the recognition of stroke among the general public and the response of emergency medical services. Specialised stroke ambulances (mobile stroke units) have been piloted in many cities to speed up the diagnosis, triage, and emergency treatment of people with acute stroke symptoms. Hospital-based interdisciplinary stroke units remain the central feature of a modern stroke service. Many have now developed a role in the very early phase (hyperacute units) plus outreach for patients who return home (early supported discharge services). Different levels (comprehensive and primary) of stroke centre and telemedicine networks have been developed to coordinate the various service components with specialist investigations and interventions including rehabilitation. Major challenges include the harmonisation of resources for stroke across the whole patient journey (including the rapid, accurate triage of patients who require highly specialised treatment in comprehensive stroke centres) and the development of technology to improve communication across different parts of a service.

Abstract
OBJECTIVES This study aimed to identify the influencing factors associated with long onset-to-door time and establish predictive models that could help to assess the probability of prehospital delay in populations with a high risk for stroke. MATERIALS AND METHODS Patients who were diagnosed with acute ischemic stroke (AIS) and hospitalized between 1 November 2018 and 31 July 2019 were interviewed, and their medical records were extracted for data analysis. Two machine learning algorithms (support vector machine and Bayesian network) were applied in this study, and their predictive performance was compared with that of the classical logistic regression models after using several variable selection methods. Timely admission (onset-to-door time < 3 hr) and prehospital delay (onset-to-door time ≥ 3 hr) were the outcome variables. We computed the area under curve (AUC) and the difference in the mean AUC values between the models. RESULTS A total of 450 patients with AIS were enrolled; 57 (12.7%) with timely admission and 393 (87.3%) patients with prehospital delay. All models, both those constructed by logistic regression and those by machine learning, performed well in predicting prehospital delay (range mean AUC: 0.800-0.846). The difference in the mean AUC values between the best performing machine learning model and the best performing logistic regression model was negligible (0.014; 95% CI: 0.013-0.015). CONCLUSIONS Machine learning algorithms were not inferior to logistic regression models for prediction of prehospital delay after stroke. All models provided good discrimination, thereby creating valuable diagnostic programs for prehospital delay prediction.

Abstract
Background The rate of intravenous thrombolysis for acute ischaemic stroke remains low in China. We investigated whether the implementation of a citywide Acute Stroke Care Map (ASCaM) is associated with an improvement of acute stroke care quality in a Chinese urban area. Methods The ASCaM comprises 10 improvement strategies and has been implemented through a network consisting of 20 tertiary hospitals. We identified 7827 patients with ischaemic stroke admitted from April to October 2017, and 506 patients underwent thrombolysis were finally included for analysis. Results Compared with ‘pre-ASCaM period’, we observed an increased rate of administration of tissue plasminogen activator within 4.5 hours (65.4% vs 54.5%; adjusted OR, 1.724; 95% CI 1.21 to 2.45; p=0.003) during ‘ASCaM period’. In multivariate analysis models, ‘ASCaM period’ was associated with a significant reduction in onset-to-door time (114.1±55.7 vs 135.7±58.4 min, p=0.0002) and onset-to-needle time (ONT) (169.2±58.1 vs 195.6±59.3 min, p<0.0001). Yet no change was found in door-to-needle time. Clinical outcomes such as symptomatic intracranial haemorrhage, favourable functional outcome (modified Rankin Scale ≤2) and in-hospital mortality remained unchanged. Conclusion The implementation of ASCaM was significantly associated with increased rates of intravenous thrombolysis and shorter ONT. The ASCaM may, in proof-of-principle, serve as a model to reduce treatment delay and increase thrombolysis rates in Chinese urban areas and possibly other highly populated Asian regions.

Abstract
BACKGROUND AND PURPOSE Stroke is a medical emergency that demands early recognition for time sensitive acute management. Knowledge about stroke in public has not been found satisfactory in most of the studies worldwide. Studies describing the awareness of public about recognition of stroke and its treatment from Saudi Arabia (SA) are deficient. This study aimed to assess the knowledge of general population living in the Eastern Province of SA about stroke in relation to recognition of warning signs, risk factors and available acute treatment. METHODS A prospective, cross sectional study was conducted using a structured questionnaire distributed through an electronic web site over a period of six months. The data was analyzed with SPSS version 22.0. RESULTS Among a total of 1,213 respondents, 62.4% were women. Three fourth identified the affected organ correctly. Psychological stress was the most commonly identified risk factor (73.5%) followed by hypertension (63.8%). More than half of the respondents (58.5%) were not aware of diabetes mellitus as a risk factor for stroke. Speech difficulty was the most commonly identified stroke warning sign (64.4%) followed by focal weakness (62.4%). More than half (59.9%) did not recognize facial asymmetry as stroke warning sign. Nearly three fourth of the participants were unaware of t-PA (73.7%) and nearest available health care center for acute stroke management (74.9%). CONCLUSION Our survey found the stroke literacy in the population of the Eastern Province of SA as non- satisfactory and highlights the importance of taking immediate measure such as mass media campaign and hospital based activities to improve it.

Pre-Hospital Delay in Patients with Acute Ischemic Stroke in a Multicenter Stroke Registry: K-PLUS. J Stroke Cerebrovasc Dis 2020; 29:105284. [PMID: 33066912 DOI: 10.1016/j.jstrokecerebrovasdis.2020.105284] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2020] [Revised: 08/09/2020] [Accepted: 08/23/2020] [Indexed: 11/25/2022] Open
Abstract
PURPOSE There is scant data related to prehospital delay in cases of acute ischemic stroke from multicenter studies conducted after change of the therapeutic window of intravenous tissue plasminogen activator (iv-tPA) administration to within 4.5 h of onset. We investigated factors causing prehospital delay and their associations with clinical outcomes using data from a regional multicenter stroke registry. METHODS Data from the multicenter regional stroke registry were analyzed. Patients admitted within 24 h of the last known well time were categorized according to whether their admission was early (≤ 4 h; n = 2350) or delayed (> 4 h; n = 2752). We then compared patients' backgrounds and outcomes between the two groups. RESULTS Five-thousand, one-hundred two patients presented at hospitals within 24 h of onset. On multivariate analysis, atrial fibrillation, higher NIHSS score on admission, anterior circulation stroke, detection of symptoms immediately after onset, and emergency system use were positively associated with early admission, whereas modified Rankin Scale (mRS) score before onset, onset at home, diabetes, current smoking, dementia and symptom detection between 00:00 and 06:00 h were negatively associated. Early admission was associated with mRS scores of 0-2 at discharge independent of backgrounds, stroke severity, and thrombolytic therapy (odds ratio, 1.56; 95% confidence interval, 1.32-1.84). CONCLUSIONS Certain patient factors relating to prehospital delay, such as lack of awareness of onset or non-cardioembolic etiology, are crucial but often inevitable. However, earlier admission was associated mRS scores of 0-2 independent of other factors. This study may help to plan educational activities to general population or public awareness campaigns.

[PMID: 32652889 PMCID: PMC7428498 DOI: 10.1002/brb3.1743] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2020] [Revised: 06/09/2020] [Accepted: 06/12/2020] [Indexed: 01/01/2023] Open
Abstract
OBJECTIVE The Chinese stroke emergency map (SEM) was implemented in 2017 to reduce prehospital and hospital delays for acute ischemic stroke (AIS) patients suitable for intravenous recombinant tissue plasminogen activator (rt-PA) thrombolysis. However, data on the time delay following the implementation of an SEM in China are limited. METHODS Data for suspected stroke patients from the SEM registry center of Taiyuan, Shanxi Province, from August 2017 to July 2019, patients' characteristics, thrombolysis rate, and functional outcome at 90 days were analyzed. RESULTS One thousand seven hundred and eighty six patients who arrived at hospitals within 4.5 hr of onset were included; 35.9% arrived by emergency medical services (EMSs), and 1,207 (67.6%) of the population received intravenous rt-PA. As a result of the SEM, the number of patients treated with rt-PA increased from 63.9% in phase 1 (August 2017 to July 2018) to 70.5% in phase 2 (August 2018 to July 2019). The median onset-to-door and onset-to-needle times decreased by five minutes (100 [IQR: 62-135] vs. 105 [IQR: 70-145], p = .005) and nine minutes (158 [IQR: 124-197] vs. 167 [IQR: 132-214], p = .001), respectively. Patients in phase 2 achieved greater independent function outcome at 90 days (79.9% vs. 72.1%; adjusted odds ratio, 2.010; 95% confidence interval, 1.444-2.798). The binary logistic regression models revealed that shorter onset-to-needle time (OR: 0.994; 95% CI: 0.992-0.997; p < .001) and lower baseline NIHSS scores (OR: 39.120; 95% CI: 23.477-65.188; p < .001 and OR: 18.324; 95% CI: 11.425-29.388; p < .001 and OR: 3.123; 95% CI: 2.044-4.773; p < .001) were significant predictors for the independent function outcome. CONCLUSION The implementation of a stroke emergency map is more likely to reduce prehospital delays and improve function outcomes. Future efforts should attempt to increase EMS usage.

Temporal Trends and Risk Factors for Delayed Hospital Admission in Suspected Stroke Patients. J Clin Med 2020; 9:jcm9082376. [PMID: 32722432 PMCID: PMC7464858 DOI: 10.3390/jcm9082376] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2020] [Revised: 07/20/2020] [Accepted: 07/22/2020] [Indexed: 12/31/2022] Open
Abstract
(1) Background: The benefit of acute ischemic stroke (AIS) treatment declines with any time delay until treatment. Hence, factors influencing the time from symptom onset to admission (TTA) are of utmost importance. This study aimed to assess temporal trends and risk factors for delays in TTA. (2) Methods: We included 1244 consecutive patients from 2015 to 2018 with suspected stroke presenting within 24 h after symptom onset registered in our prospective, pre-specified hospital database. Temporal trends were assessed by comparing with a cohort of a previous study in 2006. Factors associated with TTA were assessed by univariable and multivariable regression analysis. (3) Results: In 1244 patients (median [IQR] age 73 [60–82] years; 44% women), the median TTA was 96 min (IQR 66–164). The prehospital time delay reduced by 27% in the last 12 years and the rate of patients referred by Emergency medical services (EMS) increased from 17% to 51% and the TTA for admissions by General Practitioner (GP) declined from 244 to 207 min. Factors associated with a delay in TTA were stroke severity (beta−1.9; 95% CI–3.6 to −0.2 min per point NIHSS score), referral by General Practitioner (GP, beta +140 min, 95% CI 100–179), self-admission (+92 min, 95% CI 57–128) as compared to admission by emergency medical services (EMS) and symptom onset during nighttime (+57 min, 95% CI 30–85). Conclusions: Although TTA improved markedly since 2006, our data indicates that continuous efforts are mandatory to raise public awareness on the importance of fast hospital referral in patients with suspected stroke by directly informing EMS, avoiding contact of a GP, and maintaining high effort for fast transportation also in patients with milder symptoms.
