Tworek K, Tomaszewska A, Owecka B, Fryska Z, Marcinkowski JT, Owecki M. 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. [PMID: 37949030 DOI: 10.1016/j.jstrokecerebrovasdis.2023.107465] [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: 08/02/2023] [Revised: 10/06/2023] [Accepted: 10/31/2023] [Indexed: 11/12/2023] Open
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.

Comparing 5G mobile stroke unit and emergency medical service in patients acute ischemic stroke eligible for t-PA treatment: A prospective, single-center clinical trial in Ya'an, China. Brain Behav 2023; 13:e3231. [PMID: 37632149 PMCID: PMC10636411 DOI: 10.1002/brb3.3231] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/27/2023] [Revised: 07/12/2023] [Accepted: 08/09/2023] [Indexed: 08/27/2023] Open
Abstract
BACKGROUND This study aims to assess and compare the functional outcomes of patients with acute ischemic stroke (AIS) eligible for tissue plasminogen activator (t-PA) treatment who received care from either a fifth-generation(5G) mobile stroke unit (MSU) or traditional emergency medical service (EMS). METHOD The study recruited patients between February 2020 and January 2022, with the final 90-day follow-up concluded in April 2022. Prior to enrollment, patients were assigned to either EMS or MSU care based on predetermined rules. The primary outcome measure was the Modified Rankin Scale (mRS) score at 90 days, with secondary outcome measures including time metrics, mRS and National Institutes of Health Stroke Scale scores at 7-day follow-up, and hospitalization costs. RESULTS Of the 2281 enrolled patients, 207 were eligible for t-PA treatment, with 101 allocated to MSU care and 106 to EMS care. The percentage of patients achieving a favorable mRS score (0-2) at 90 days was 82.2% in the MSU group compared to 72.6% in the EMS group (p < .05). Median times from symptom onset to thrombolysis were 146 min in the MSU group and 204 min in the EMS group, while median times from ambulance alert to computed tomography (CT) completion were 53 and 128 min, respectively. Hospitalization charges averaged approximately $3592 in the MSU group and $4800 in the EMS group. CONCLUSIONS Our findings indicate that 5G MSU care significantly reduces the time from symptom onset to stroke diagnosis and intravenous thrombolysis in patients with AIS, resulting in improved functional outcomes compared to EMS care. As China continues its deployment of 5G technology and other digital infrastructures, the adoption of 5G MSU care on a broader scale may eventually supplant traditional stroke treatment approaches.

Characterization of a Temporal Profile of Biomarkers as an Index for Ischemic Stroke Onset Definition. J Clin Med 2021; 10:jcm10143136. [PMID: 34300300 PMCID: PMC8307571 DOI: 10.3390/jcm10143136] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2021] [Revised: 07/07/2021] [Accepted: 07/13/2021] [Indexed: 01/01/2023] Open
Abstract
Background and purpose: Stroke is a dynamic process in terms of molecular mechanisms, with prominent glutamate-mediated excitotoxicity at the onset of symptoms followed by IL-6-mediated inflammation. Our aim was to study a serum glutamate/IL-6 ratio as an index for stroke onset definition. Methods: A total of 4408 ischemic stroke patients were recruited and then subdivided into four quartiles according to latency time in minutes (0–121, 121–185, 185–277 and >277). Latency time is defined as the time between stroke onset and treatment at the neurological unit. The primary endpoint of the study was the association of early latency times with different clinical aspects and serum markers. Serum glutamate and interleukin-6 (IL-6) levels at admission were selected as the main markers for excitotoxicity and inflammation, respectively. Results: Glutamate serum levels were significantly higher in the earlier latency time compared with the higher latency times (p < 0.0001). IL-6 levels were lower in early latency times (p < 0.0001). Patients with a glutamate/IL-6 index on admission of >5 were associated with a latency time of <121 min from the onset of symptoms with a sensitivity of 88% and a specificity of 80%. Conclusions: The glutamate/IL-6 index allows the development of a ratio for an easy, non-invasive early identification of the onset of ischemic stroke symptoms, thus offering a new tool for selecting early stroke patient candidates for reperfusion therapies.

Factors delaying intravenous thrombolytic therapy in acute ischaemic stroke: a systematic review of the literature. J Neurol 2020; 268:2723-2734. [PMID: 32206899 DOI: 10.1007/s00415-020-09803-6] [Citation(s) in RCA: 21] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2019] [Revised: 03/17/2020] [Accepted: 03/18/2020] [Indexed: 01/01/2023]
Abstract
BACKGROUND/AIMS This review examined factors that delay thrombolysis and what management strategies are currently employed to minimise this delay, with the aim of suggesting future directions to overcome bottlenecks in treatment delivery. METHODS A systematic review was performed according to PRISMA guidelines. The search strategy included a combination of synonyms and controlled vocabularies from Medical Subject Headings (MeSH) and EmTree covering brain ischemia, cerebrovascular accident, fibrinolytic therapy and Alteplase. The search was conducted using Medline (OVID), Embase (OVID), PubMed and Cochrane Library databases using truncations and Boolean operators. The literature search excluded review articles, trial protocols, opinion pieces and case reports. Inclusion criteria were: (1) The article directly related to thrombolysis in ischaemic stroke, and (2) The article examined at least one factor contributing to delay in thrombolytic therapy. RESULTS One hundred and fifty-two studies were included. Pre-hospital factors resulted in the greatest delay to thrombolysis administration. In-hospital factors relating to assessment, imaging and thrombolysis administration also contributed. Long onset-to-needle times were more common in those with atypical, or less severe, symptoms, the elderly, patients from lower socioeconomic backgrounds, and those living alone. Various strategies currently exist to reduce delays. Processes which have achieved the greatest improvements in time to thrombolysis are those which integrate out-of-hospital and in-hospital processes, such as the Helsinki model. CONCLUSION Further integrated processes are required to maximise patient benefit from thrombolysis. Expansion of community education to incorporate less common symptoms and provision of alert pagers for patients may provide further reduction in thrombolysis times.

Abstract
Background The treatment of stroke is dependent on a narrow therapeutic time window that requires interventions to be emergently pursued. Despite recent "FAST" initiatives that have underscored "time is brain," many patients still fail to present within the narrow time window to receive maximum treatment benefit from advanced stroke therapies, including recombinant tissue plasminogen activator (tPA) and mechanical thrombectomy. The convergence of emergency medical services, telemedicine, and mobile technology, including transportable computed tomography scanners, has presented a unique opportunity to advance patient stroke care in the prehospital field by shortening time to hyperacute stroke treatment with a mobile stroke unit (MSU). Summary In this review, we provide a look at the evolution of the MSU into its current status as well as future directions. Our summary statement includes historical and implementation information, economic cost, and published clinical outcome and time metrics, including the utilization rate of thrombolysis. Key Messages Initially hypothesized in 2003, the first MSUs were launched in Germany and adopted worldwide in acute, prehospital stroke management. These specialized ambulances have made the diagnosis and treatment of many neurological emergencies, in addition to ischemic and hemorrhagic stroke, possible at the emergency site. Providing treatment as early as possible, including within the prehospital phase of stroke management, improves patient outcomes. As MSUs continue to collect data and improve their methods, shortened time metrics are expected, resulting in more patients who will benefit from faster treatment of their acute neurological emergencies in the prehospital field.

Abstract
Context: Early thrombolytic therapy in acute ischemic stroke has proven to reduce the associated morbidity. Many factors are in play, delaying the arrival of patients. Aim: To ascertain the factors causing delay in patients with acute ischemic stroke presenting beyond the window period of thrombolysis in and around Chennai, Tamil Nadu, India. Subjects and Methods: An observational cross-sectional study involving 200 patients with acute ischemic stroke at Sri Ramachandra Medical College, Chennai, India between June 2015 and July 2016 was conducted. The data was collected by direct interview using a questionnaire designed to study factors such as age, family structure, residence, distance from the hospital, education status, wake-up stroke, transport, symptoms, knowledge about symptoms, seriousness of symptoms, waiting on symptoms, insurance and point of admission. Data was analyzed for means, frequencies, percentages and multiple linear regression analysis was performed to identify factors independently influencing delayed arrival. Results: Mean age of the cohort was 58.08 years: 142 men and 58 women. Mean time of delayed arrival was 13.6 hours. Multiple linear regression analysis revealed that seriousness of symptoms (P = 0.001), residence (P = 0.001), point of admission (P = 0.033) and wake-up stroke (P = 0.005) were statistically significant predictors of delayed arrival. Conclusion: Patients not perceiving their symptoms to be serious, residing in a rural area, not arriving to the emergency, and having a stroke while awake were all the significant predictors of pre-hospital delay in our study. Awareness among the masses about symptom recognition and early arrival to a tertiary care center will reduce the delay and associated morbidity. Primary care physicians notably play a significant role in educating patients at risk, identifying the symptoms of stroke and referring them for thrombolysis.

Abstract
Objective Stroke patients often came late to hospital and arrived beyond the therapeutic time window for thrombolytic therapy. We studied the time from stroke onset to arrival at Accident and Emergency (A&E) department and examined what barred them from early medical attendance. Methods All acute stroke patients attending A&E between 15 March 1999 to 14 June 1999 were recruited. For those brought in by ambulance, their time intervals were divided into three: phase I was between stroke onset to call 999; phase II was between call 999 to A&E arrival; and phase III was between A&E arrival to being seen by doctor. For those who did not come by ambulance, they were divided into two groups: those who consulted other doctors and those who did not consult other doctors before coming to A&E. Their time lags from stroke onset to A&E consultation were compared. Results One hundred and fifteen stroke patients were consecutively recruited. Sixty-five ambulance users had median time for phase I as 151 minutes, for phase II as 32 minutes, for phase III as 17 minutes. The total median time lag was 190 minutes. Fifty were ambulance non-users. For those who did not consult other doctors before A&E attendance, the median time lag was 641 minutes. For those who consulted others doctors before A&E attendance, their median time lag was 3,672 minutes. As a group their median time lag was 950 minutes. For the 65 ambulance users, we further studied the time intervals between A&E arrival and being seen by doctors; and the median waiting time for doctors was 17 (range 0 to 60) minutes. Conclusions Public education was of paramount importance. Some common stroke signs could be widely propagated for recognition. Phase I should be less than 80 minutes. The median time for phase II would likely remain to be 32 minutes. Further shortening could be achieved in phase III. As category III & IV patients were most likely potential candidates for thrombolysis, they should be seen within 15 minutes. This would leave only 53 minutes for clinical assessment, CT brain and preparation of thrombolytic agent. These measures could increase the chance of providing thrombolytic treatment within the therapeutic time window.

Abstract
Despite the availability of thrombolytic and endovascular therapy for acute ischemic stroke, many patients are ineligible due to delayed hospital arrival. The identification of factors related to either early or delayed hospital arrival may reveal potential targets of intervention to reduce prehospital delay and improve access to time-critical thrombolysis and clot retrieval therapy. Here, we have reviewed studies reporting on factors associated with either early or delayed hospital arrival after stroke, together with an analysis of stroke onset to hospital arrival times. Much effort in the stroke treatment community has been devoted to reducing door-to-needle times with encouraging improvements. However, this review has revealed that the median onset-to-door times and the percentage of stroke patients arriving before the logistically critical 3 h have shown little improvement in the past two decades. Major factors affecting prehospital time were related to emergency medical pathways, stroke symptomatology, patient and bystander behavior, patient health characteristics, and stroke treatment awareness. Interventions addressing these factors may prove effective in reducing prehospital delay, allowing prompt diagnosis, which in turn may increase the rates and/or efficacy of acute treatments such as thrombolysis and clot retrieval therapy and thereby improve stroke outcomes.

Abstract
BACKGROUND AND PURPOSE The onset of wake-up stroke and daytime-unwitnessed stroke is unclear. Though the clinical importance is similar by both being excluded from reperfusion therapy, the characteristics of daytime-unwitnessed stroke are less known than that of wake-up stroke. Here, we compared the characteristics between daytime-unwitnessed stroke and wake-up stroke. METHODS Unclear-onset (i.e., last-known normal time ≠ first-found abnormal time) stroke patients admitted within 24 h of recognition of stroke between February 2011 and October 2013 were reviewed. Demographics and clinical and imaging variables were compared between patients with daytime-unwitnessed stroke and those with wake-up stroke. RESULTS Among the 762 ischemic stroke patients, 276 (36.2%) had unclear-onset stroke (104 daytime-unwitnessed stroke and 172 wake-up stroke). Compared to wake-up stroke, daytime-unwitnessed stroke patients had a higher prevalence of cardioembolic stroke and more frequently presented altered mental status (p < 0.001) and/or aphasia (p < 0.001) with more severe neurological deficit (p < 0.001). However, the time from symptom recognition to hospital arrival was shorter (p < 0.001), and diffusion-weighted image-fluid-attenuated inversion recovery image mismatch (p = 0.02) and perfusion-diffusion mismatch (p = 0.001) were also more frequently observed in daytime-unwitnessed stroke. Finally, the proportion of patients eligible for thrombolysis (p < 0.001) was higher in daytime-unwitnessed stroke patients. CONCLUSIONS Clinical and imaging characteristics of daytime-unwitnessed stroke significantly differ from those of wake-up stroke. Daytime-unwitnessed stroke patients are more likely to receive reperfusion therapy, as they arrive at the hospital earlier after symptom recognition, compared to wake-up stroke patients.

Abstract
This study aimed to explore pre-hospital delay and its associated factors in first-ever stroke registered in communities from three cities in China. The rates of delay greater than or equal to 2 hours were calculated and factors associated with delays were determined by non-conditional binary logistic regression, after adjusting for different explanatory factors. Among the 403 cases of stroke with an accurate documented time of prehospital delay, the median time (interquartile range) was 4.00 (1.50–14.00) hours. Among the 544 cases of stroke with an estimated time range of prehospital delay, 24.8% of patients were transferred to the emergency department or hospital within 2 hours, only 16.9% of patients with stroke were aware that the initial symptom represented a stroke, only 18.8% used the emergency medical service and one-third of the stroke cases were not identified by ambulance doctors. In the multivariate analyses, 8 variables or sub-variables were identified. In conclusion, prehospital delay of stroke was common in communities. Thus, intervention measures in communities should focus on education about the early identification of stroke and appropriate emergency medical service (EMS) use, as well as the development of organized stroke care.

Abstract
Stroke is the third leading cause of death of people in the world today and the highest cause of disability and handicap, producing a huge burden on individuals and society more broadly. Yet unlike its counterpart acute myocardial infarction (AMI), little has been done to promote early intervention in evolving strokes. Recommendations from the American Heart Association and more recently the European Stroke Initiative are available; however, in Australia (as with many other countries) practice guidelines are scarce and clinicians largely operate in an ad hoc manner with little awareness of ‘best practice’. The controversial role of thrombolysis with limitations in respect to selecting appropriate patients, in addition to a small window of opportunity for therapeutic beneficial effects and a high risk for haemorrhage, has inhibited its widespread application. As such, emergent stroke management clearly lags behind that of AMI–both with respect to the range of treatment options and the application of best practice. This paper reviews the literature regarding best practice management of evolving stroke and the crucial role of nurses in triaging and managing patients to deliver optimal outcomes within the Australian context.

Abstract
Intravenous thrombolysis with recombinant tissue-type plasminogen activator is the approved treatment for acute ischemic stroke within 4.5 h from symptoms onset. Evidence suggests the earlier treatment was given, the greater the chance of a favorable outcome. We investigated if the delay in hospital presentation has been modified in the past 8 years. Acute ischemic strokes admitted to the Emergency Department of the Careggi Hospital, Florence from March 2004 to December 2012 were prospectively collected in the Careggi Hospital Stroke Registry. Proportion of patients presenting ≤ 2 h, 2-3.5, 3.5-6, and >6 h from symptom onset or with awakening stroke were compared. From March 2004 to December 2012, 3,856 patients with acute ischemic stroke arrived to the Careggi Emergency Department. During the period, 28.3 % of patients arrived ≤ 2 h from symptoms onset and 9.8 % between 2 and 3.5 h. The proportion of time-eligible patients is steady in the first years with a slight increase in 2011 and 2012. Early presentation is significantly associated with younger age, intracerebral hemorrhage, and stroke severity. In this study, about one-third of acute ischemic strokes arrived at the Emergency Department within the therapeutic time-window for intravenous thrombolysis. There is only a slight increase in early presentation through the period, mainly in the last 2 years. Additional efforts are required to impact deeply on the rates of time-eligible patients.

Abstract
Excessive delay of presentation for stroke in China is reported. In this study, an intervention trial was conducted to promote urgent therapy for acute ischemic stroke. Two communities in Changsha were selected as either intervention or control community from November 2007 to December 2011. Public and professional education was regularly implemented in the intervention community. Publics' knowledge about early identification and urgent therapy of ischemic stroke was surveyed before and after intervention in the two communities. During the intervention period, first-ever ischemic stroke cases occurring in the intervention community (intervention group) and that in the control community (control group) were collected and followed for 90 days. After intervention, the publics' knowledge levels in the intervention community improved significantly. Intervention group' average presentation time was shorter than control group (8.3 ± 5.8 vs. 10.5 ± 6.5 h, P = 0.018). Percentage of presentation time within 3 h (48.0 %), the rate of ambulance use (59.0 %), and thrombolytic therapy (9.3 %) in the intervention group was all obviously higher than that in the control group (21.5, 41.3, and 4.5, respectively). When admitted, the intervention group had lower mean systolic blood pressure (160.8 ± 26.7 vs. 164.7 ± 26.8 mmHg, P = 0.000) than control group. Survivors in the intervention group were more likely to be in higher Barthel index scoring groups than that in the control group at day 90 [(75, 50-100) vs. (65, 35-90), P = 0.035]. Public and professional education may promote prompt presentation and urgent therapy for ischemic stroke, which may be helpful for patients' prognosis.

Abstract
INTRODUCTION It is crucial to understand the reasons behind pre- and in-hospital delays to improve nationwide access to effective treatment for acute stroke. AIMS To evaluate the pre- and in-hospital delays and to compare the intravenous (IV) thrombolysis rates in the urban and rural areas of the Province of Pomerania, Poland. MATERIALS & METHODS We evaluated the medical records of 2134 patients treated in the stroke units (SUs) and consecutively reported to the Pomeranian Stroke Register from June 2006-December 2007. RESULTS The time of ischaemic stroke onset was known in 488 (59%) of the 834 urban patients and in 744 (70%) of the 1063 rural patients (P < 0.001). The proportion of patients who called the emergency medical services with a delay of >45 min was similar in both locations: urban, 314/488 (64.3%) vs rural, 490/744 (65.8%). Although the proportion of patients who reached the emergency room within 3 h was higher in the rural areas (29.0% vs 24.3%; P = 0.02), only 4.2% of these patients received IV thrombolysis compared with 23.1% in the urban areas (P < 0.001). The proportion of patients who did not seek any kind of professional medical help prior to admission was lower in the rural areas (29/744 (3.9%) vs urban 50/488 (10.2%)) (P < 0.001). CONCLUSIONS Pre-hospital delays reduced the number of patients eligible for IV thrombolysis in both rural and urban areas. The low proportion of patients treated with IV thrombolysis in rural SUs may be attributed to ineffective in-hospital procedures.

Abstract
BACKGROUND Delayed presentation to hospital after an acute stroke is a major explanation given for low thrombolysis rates. This study aimed to investigate the factors associated with delays in presentation after an acute stroke and changes after a mass media campaign. METHODS AND RESULTS Data were from a population-based study involving 1392 patients with first-ever strokes between 2002 and 2010 in a multiethnic South London population. Associations were determined between prehospital delay (≥3 hours) and variables of interest, including ethnicity, by using multivariate logistic regression analyses. Differences in prehospital delay and thrombolysis rates were determined for the period immediately before and after the FAST mass media campaign (2007/2008 versus 2009/2010). The median (Q(1) to Q(3)) time to presentation was 4.73 (1.55 to 12.70) hours, and 550 (39.5%) presented within 3 hours of symptom onset. In multivariate analysis, patients of black ethnicity had increased odds of delay (odds ratio: 1.63; 95% confidence interval, 1.11 to 2.38), whereas those with more severe strokes characterized by a higher National Institutes of Health Stroke Scale score (odds ratio: 0.35; 95% confidence interval, 0.20 to 0.61) had reduced odds of delay. There was no difference in the proportion of patients who arrived within 3 hours (P=0.30) in the period immediately before and after the FAST campaign (40.7% in 2007/2008 versus 44.9% in 2009/2010). Among patients with ischemic stroke, 119 (11.0%) received thrombolysis between 2002 and 2010, with no difference observed between the pre- and postcampaign periods (16.9% versus 16.4%). CONCLUSION Significant delays in seeking care after stroke still occur in this population despite efforts to increase public awareness. Future educational programs must identify and specifically address factors that influence behavior and should target those at higher risk of delay.

Abstract
WHAT IS KNOWN AND OBJECTIVE Thrombolysis is currently the only evidence-based pharmacological treatment available for acute ischaemic stroke (AIS); however, its current utilization is suboptimal (administered to <3% of AIS patients). The aim of this article was to identify the potential barriers to the use of thrombolysis via a review of the available literature. METHODS Medline, Embase, International Pharmaceutical Abstracts and Google Scholar were searched to identify relevant original articles, review papers and other literature published in the period 1995-2011. RESULTS AND DISCUSSION Several barriers to the utilization of thrombolysis in stroke have been identified in the literature and can be broadly classified as 'preadmission' barriers and 'post-admission' barriers. Preadmission barriers include patient and paramedic-related factors leading to late patient presentation for treatment (i.e. outside the therapeutic time window for the administration of thrombolysis). Post-admission barriers include in-hospital factors, such as suboptimal triage of stroke patients and inefficient in-hospital acute stroke care systems, a lack of appropriate infrastructure and expertise to administer thrombolysis, physician uncertainty in prescribing thrombolysis and difficulty in obtaining informed consent for thrombolysis. Suggested strategies to overcome these barriers include public awareness campaigns, prehospital triage by paramedics, hospital bypass protocols and prenotification systems, urgent stroke-unit admission, on-call multidisciplinary acute stroke teams, urgent neuroimaging protocols, telestroke interventions and risk-assessment tools to aid physicians when considering thrombolysis. Additionally, greater pharmacists' engagement is warranted to help identify the people at risk of stroke and support preventative strategies, and provide the public with information regarding the recognition of stroke, as well as facilitate the access and use of thrombolysis. WHAT IS NEW AND CONCLUSION The most effective interventions appear to be those comprising several strategies and those that target more than one barrier simultaneously. Therefore, optimal utilization of thrombolysis requires a systematic, integrated multidisciplinary approach across the continuum of acute care.

Abstract
BACKGROUND Time is essential for the treatment of acute stroke. Much time is lost outside the hospital, either due to failure in identifying stroke symptoms or due to a delay in notification or transport. We review studies reporting factors associated with better stroke knowledge and shorter time delays. We summarise the evidences for the effect of stroke knowledge and education on people's reaction in the acute situation of stroke. METHODS We searched MEDLINE for studies reporting factors associated with prehospital time of stroke patients, or knowledge of stroke symptoms. Further, we searched for studies reporting educational interventions aimed at increasing stroke symptom knowledge in the population. FINDINGS We included a total of 182 studies. Surprisingly, those factors associated with better stroke knowledge such as education and sociodemographic variables were not related to shorter time delays. Few studies report shorter time delays or better stroke knowledge in persons having suffered a previous stroke. Factors associated with shorter time delays were more severe stroke and symptoms regarded as serious, but not better knowledge about the most frequent symptoms such as hemiparesis or disorders of speech. Only 25-56% of patients recognised their own symptoms as stroke. While stroke education increases the knowledge of warning signs, a few population studies measured the impact of education on time delays; in such studies, time delays decreased after education. This may partly be mediated by better organisation of EMS and hospitals. INTERPRETATION There is a discrepancy between theoretical stroke knowledge and the reaction in an acute situation. Help-seeking behaviour is more dependent on the perceived severity of symptoms than on symptom knowledge. Bystanders play an important role in the decision to call for help and should be included in stroke education. Education is effective and should be culturally adapted and presented in a social context. It is unclear which educational concept is best suited to enhance symptom recognition in the acute situation of stroke, especially in view of discrepancies between knowledge and action.

Abstract
Early admission to stroke unit (SU) and factors that may cause admission delay represent relevant issues to obtain an optimal management of acute stroke. This study was aimed at recording timing from clinical onset to admission to our SU and to identify the reasons for delay. We prospectively examined acute stroke patients consecutively admitted to the Perugia SU. Baseline characteristics of stroke patients, stroke type and etiology, time from symptom onset to arrival in the SU were obtained from the Hospital-Based Perugia Stroke Registry. 60.8% of 2,213 consecutive stroke patients admitted to the SU arrived within 6 hrs and 39.2% after 6 hrs. Underestimation of symptoms was the cause of delay in 48.7% of cases. Younger age, especially for females, ischemic stroke, mild and/or unspecific symptoms and the underestimation of symptoms seem to be the main reasons for delayed arrival in the SU. To increase the proportion of stroke patients arriving in the SU within 3 hr of symptom onset, it is necessary to improve public and general practitioner awareness of stroke through educational programs.

Abstract
The purpose of this study was to systematically review and summarize prehospital and in-hospital stroke evaluation and treatment delay times. We identified 123 unique peer-reviewed studies published from 1981 to 2007 of prehospital and in-hospital delay time for evaluation and treatment of patients with stroke, transient ischemic attack, or stroke-like symptoms. Based on studies of 65 different population groups, the weighted Poisson regression indicated a 6.0% annual decline (P<0.001) in hours/year for prehospital delay, defined from symptom onset to emergency department arrival. For in-hospital delay, the weighted Poisson regression models indicated no meaningful changes in delay time from emergency department arrival to emergency department evaluation (3.1%, P=0.49 based on 12 population groups). There was a 10.2% annual decline in hours/year from emergency department arrival to neurology evaluation or notification (P=0.23 based on 16 population groups) and a 10.7% annual decline in hours/year for delay time from emergency department arrival to initiation of computed tomography (P=0.11 based on 23 population groups). Only one study reported on times from arrival to computed tomography scan interpretation, two studies on arrival to drug administration, and no studies on arrival to transfer to an in-patient setting, precluding generalizations. Prehospital delay continues to contribute the largest proportion of delay time. The next decade provides opportunities to establish more effective community-based interventions worldwide. It will be crucial to have effective stroke surveillance systems in place to better understand and improve both prehospital and in-hospital delays for acute stroke care.

Abstract
Stroke has a greater effect on women than men because women have more events and are less likely to recover. Age-specific stroke rates are higher in men, but, because of their longer life expectancy and much higher incidence at older ages, women have more stroke events than men. With the exception of subarachnoid haemorrhage, there is little evidence of sex differences in stroke subtype or severity. Although several reports found that women are less likely to receive some in-hospital interventions, most differences disappear after age and comorbidities are accounted for. However, sex disparities persist in the use of thrombolytic treatment (with alteplase) and lipid testing. Functional outcomes and quality of life after stroke are consistently poorer in women, despite adjustment for baseline differences in age, prestroke function, and comorbidities. Here, we comprehensively review the epidemiology, clinical presentation, medical care, and outcomes of stroke in women.

Abstract
Introduction: Intravenous thrombolysis has been shown to improve outcome after acute cerebral infarction if given within 3 hours of symptom onset. There are no data in Singapore on the timing of hospital presentation after acute cerebral infarction as well as factors and reasons for delayed presentation.
Materials and Methods: As intravenous thrombolysis has recently been licensed for use in acute cerebral infarction in Singapore, we studied 100 consecutive acute cerebral infarction admitted to the Singapore General Hospital for timing of hospital presenta-tion, reasons associated with delay in presentation and hypothetical acceptance of intravenous thrombolysis.
Results: Only 9% of patients presented to hospital within 2 hours of symptom onset. Factors associated with hospital presentation within 2 hours were a large stroke and lack of pre-hospital consultation. Failure to recognise the severity of symptoms and inability to seek medical attention unaided were the 2 most common reasons for delayed presentation. One-third of patients or their relatives hypothetically would accept intravenous thrombolysis, suggesting that a thrombolysis service is feasible at the Singapore General Hospital. However, it would be hindered by the low proportion of patients who present early to hospital after symptom onset.
Conclusion: Our results support the need for a public education programme to highlight the identification of stroke symptoms and the need to present to hospital as soon as possible after the onset of stroke symptoms.

Abstract
An improvement in patient arrival time to stroke unit (SU) is recommended, since earlier stroke management seems to improve 'per se' functional outcome. The objective of this study was to determine if early admission influences the outcome, reduces disability and mortality at discharge and three months later independent of tlirombolytic treatment. Consecutive acute stroke patients admitted to SU between January 1st 2000 and December 31st 2003 were studied in order to analyze the actual role of acute management independent specific pharmacological treatment, we excluded subjects who underwent rt-PA. 35.8% of 2,041 consecutive stroke patients arrived within 3 hours; 62.4% within 6 hours; 37.6% arrived later. Approximately 80% of the <6 hour patients presented a National Institutes of Health Stroke Scale (NIHSS) >4 and modified Rankin Scale (mRS) score >2 in comparison with 60% of the >6 hour patients. In hospital (8.7%) and three-month (7.3%) mortality in <3 hour patients were not significantly different from what observed in >3 hour patients (6.8% and 6.1% respectively) while functional outcome after three months was better in <3 hour patients (NIHSS: 34.6 vs 15.2; mRS: 32.9% vs 16.8%). Old age, history of TIA, cardioembolic etiology, severity of neurological deficit and hemorrhagic stroke type all led to earlier arrival time. Admission within 3 hours 'per se' improves outcome and reduced disability at three months.

Abstract
BACKGROUND A limiting factor for immediate initiation of stroke therapy is delayed hospital arrival. We assessed general knowledge on and behavior during an acute stroke with particular emphasis on prehospital temporal delays and a focus on the high-risk group of patients with atrial fibrillation (AF). METHODS As part of the Berlin Acute Stroke Study (BASS), we interviewed patients admitted to hospital with symptoms of stroke using a standardized questionnaire. Cardiac rhythm was assessed by ECG and Holter monitor. Data analysis included additional stratification for age and gender. RESULTS Of a total of 558 patients (66.8 +/- 13.5 years; 45% female) diagnosed with TIA or stroke 28% interpreted their own symptoms correctly as due to stroke. Female patients reporting cardiac arrhythmias and having AF more often correctly interpreted their symptoms as stroke (P = 0.03), considered their symptoms urgent (P = 0.02), considered stroke a medical emergency (P < 0.05) and had shorter prehospital delay times (P = 0.001) compared to female patients not reporting cardiac arrhythmias. Male, younger (< 65 years) and older patient groups showed no such effect, respectively. CONCLUSION Females who know to have AF demonstrate better knowledge of stroke symptoms compared to females unaware or without this risk factor. This better knowledge translates into more appropriate behavior during an acute stroke.

Abstract
STUDY OBJECTIVE We determine the interval between stroke symptom onset and time to emergency department (ED) arrival and factors associated with delays in presentation. METHODS All patients with acute stroke presenting at 4 hospitals in a metropolitan area and consenting to an interview were prospectively included over a 12-month period, excluding patients with presentation greater than 7 days after onset of symptoms and discharge or death within 24 hours after ED arrival. Initially, National Institutes of Health Stroke Scale and times of symptom onset and of ED arrival were registered by a neurologist. Sociodemographic factors and data about the course of events were obtained by standardized interview conducted with patients or proxies. In a multivariable analysis, an extended Cox proportional hazards model was used, and hazard ratios were determined. RESULTS Primary analyses were performed for 558 interviewed patients (mean age 66.8+/-13.5 years, 45% female patients) with confirmed stroke; 452 (81%) patients had a known onset of symptoms. Median interval between symptom onset and ED arrival was 151 minutes (range 5 to 9,590 minutes). Transport by emergency medical services (adjusted hazard ratio 0.28 [95% confidence interval (CI) 0.19 to 0.41]), increasing age (hazard ratio 0.99 [95% CI 0.98 to 0.99]), greater stroke severity (National Institutes of Health Stroke Scale score; hazard ratio 0.93 [95% CI 0.90 to 0.96]), having transient ischemic attack rather than persistent symptoms (hazard ratio 0.32 [95% CI 0.22 to 0.46]) and symptoms considered urgent (hazard ratio 0.68 [95% CI 0.55 to 0.84]) were the factors most strongly associated with a shorter out-of-hospital interval. CONCLUSION There are considerable delays between stroke symptom onset and ED arrival. Programs to improve awareness of patients with stroke to seek medical help immediately may reduce unnecessary delays to ED arrival.

Abstract
Foram caracterizados os pacientes com diagnóstico de acidente vascular cerebral (AVC) isquêmico internados por período superior a 24 horas. Investigamos os fatores que influenciam a chegada precoce ou tardia do paciente ao pronto socorro, o intervalo de tempo entre a chegada e a realização de tomografia computadorizada (TC), os fatores que influenciam na permanência destes pacientes no hospital e o seu destino. Concluímos que a população atendida pelo Hospital São Paulo tem chegado ao hospital mais precocemente que há 3 anos (47% chegaram nas primeiras 3 horas de instalação) e que o fluxo interno do paciente ficou muito mais rápido, uma vez que o AVC é considerado emergência médica pela equipe de saúde. As principais complicações apresentadas pelos pacientes foram infecciosas e nos direcionam à proposta de implementação de protocolos para a melhoria aos cuidados que devem ser prestados pelos profissionais de saúde.

Abstract
Proving the efficacy of thrombolysis in improving outcome from stroke has put time to assessment of patients at the forefront for healthcare providers when organizing stroke care. The chain of recovery begins with the patient. Efforts are being made to improve the general public's understanding of stroke. However, it appears at the moment that a greater effect in reducing the delay to initial medical assessment and treatment decision is to be gained through streamlining care as soon as 911 has been called. Emergency medical services dispatchers and technicians play a key role in recognizing that a patient is having a stroke and prioritizing the transport of the patient to an appropriate facility. Emergency departments need to have clear protocols in place to ensure that physicians can make prompt treatment decisions after having fully assessed and investigated the patient. Only with all these pieces in place is the initial phase of the chain of recovery complete, with the end result that more patients have the chance to have an improved outcome from stroke.

Abstract
STUDY OBJECTIVES We determine whether a sex difference exists for acute stroke emergency department presentation. METHODS The TLL Temple Foundation Stroke Project is a prospective observational study of acute stroke management that identified 1,189 validated strokes in nonurban community EDs from February 1998 to March 2000. Structured interview of the patient and the person with the patient at symptom onset identified the symptom or symptoms that prompted the patient to seek medical attention. Interview data were available for 1,124 (94%) patients. A physician blinded to sex classified the reported symptoms into 14 categories. RESULTS Nontraditional stroke symptoms were reported by 28% of women and 19% of men (odds ratio 1.62; 95% confidence interval 1.2 to 2.2). Nontraditional stroke symptoms, pain (men 8%, women 12%) and change in level of consciousness (men 12%, women 17%), were more often reported by women. Traditional stroke symptoms, imbalance (men 20%, women 15%) and hemiparesis (men 24%, women 19%), were reported more frequently by men. Trends were also found for women to present with nonneurologic symptoms (men 17%, women 21%) and men to present with gait abnormalities (men 11%, women 8%). There was no sex difference in the mean number of symptoms reported by an individual patient. CONCLUSION This study suggests that a sex difference exists in reporting of acute stroke symptoms. Women with validated strokes present more frequently with nontraditional stroke symptoms than men. Recognition of this difference might yield faster evaluation and management of female patients with acute stroke eligible for acute therapies.

Abstract
OBJECTIVE This study aimed to identify sources and reasons for delays in the care of our acute stroke patients. METHODS Data on time interval from symptom onset or awareness to initial presentation, to neurology assessment, to performance of cranial CT scan, and demographic and medical factors associated with delays among stroke patients admitted at St. Luke's Medical Center from May to October 2000 were obtained by interview and record review. RESULTS Of 259 patients (mean age 61.5+/-13.6 years, 43% females), 63% had infarction (INF), 32% intracerebral hemorrhage (ICH) and 5% subarachnoid hemorrhage (SAH). Fifty-nine percent presented within 3 h of symptom onset or awareness, 73% within 6 h (median=2 h). Patients with ICH presented earlier than those with infarction. Reasons for delayed consultation included failure to recognize symptoms as serious and stroke-related. A non-neurologist was initially consulted in 97% of cases. Median delay from presentation to neurology evaluation was 7.5 h. Median time from presentation to brain imaging was significantly shorter for patients brought to CT-equipped facilities (2 h) than for those needing transfer to other hospitals (11.5 h). CONCLUSIONS AND RECOMMENDATIONS Patient delay in presentation is only one cause of delay in acute stroke care. Longer delays arise from healthcare-related factors such as delays in neurologist referral and neuroradiologic diagnosis. Professional and public education on the necessity of early neurologic evaluation and patient transport to CT-equipped "Stroke Centers" is recommended.

Abstract
OBJECTIVE To investigate delays in the presentation to hospital and evaluation of patients with suspected stroke. DESIGN Multicentre prospective observational study. SETTING 22 hospitals in the United Kingdom and Dublin. PARTICIPANTS 739 patients with suspected stroke presenting to hospital. MAIN OUTCOME MEASURES Time from onset of stroke symptoms to arrival at hospital, and time from arrival to evaluation by a senior doctor. RESULTS The median age of patients was 75 years, and 400 were women. The median delay between onset of symptoms and arrival at hospital was 6 hours (interquartile range 1 hour 48 minutes to 19 hours 12 minutes). 37% of patients arrived within 3 hours, 50% within 6 hours. The median delay for patients using the emergency service was 2 hours 3 minutes (47 minutes to 7 hours 12 minutes) compared with 7 hours 12 minutes (2 hours 5 minutes to 20 hours 37 minutes) for referrals from general practitioners (P<0.0001). Use of emergency services reduced delays to hospital (odds ratio 0.45, 95% confidence interval 0.23 to 0.61). The median time to evaluation by a senior doctor was 1 hour 9 minutes (interquartile range 33 minutes to 1 hour 50 minutes) but was undertaken in only 477 (65%) patients within 3 hours of arrival. This was not influenced by age, sex, time of presentation, mode of referral, hospital type, or the presence of a stroke unit. Computed tomography was requested within 3 hours of arrival in 166 (22%) patients but undertaken in only 60 (8%). CONCLUSION Delays in patients arriving at hospital with suspected stroke can be reduced by the increased use of emergency services. Over a third of patients arrive at hospital within three hours of stroke; their management can be improved by expediting medical evaluation and performing computed tomography early.

Abstract
OBJECTIVES To gain insight into people's thoughts on stroke and to inform the development of educational strategies in the community. DESIGN Focus group discussions: two groups of people who had a stroke and their carers, and two groups of members of the general public. SETTING New South Wales, Australia. PARTICIPANTS 35 people participated: 11 from the general public, 14 people who had had a stroke, and 10 carers or partners. MAIN OUTCOME MEASURES Views on risk factors, symptoms, treatment, information resources, and prevention. RESULTS All groups reported similar knowledge of risk factors. People generally mentioned stress, diet, high blood pressure, age, and smoking as causes of stroke. Participants in the community group gave little attention to symptoms. Some participants who had had a stroke did not initially identify their experience as stroke because the symptoms were not the same as those they had read about. There were mixed feelings about the extent of involvement in management decisions during hospital admission. Some felt sufficiently involved, some wanted to be more involved, and others felt incapable of being actively involved. CONCLUSIONS Symptoms of stroke are not easy to recognise because they vary so much. Presentation of information about stroke by hospital and community health services should be improved. Simple and understandable educational materials should be developed and their effectiveness monitored.

Abstract
To examine the current emergency referral and care for acute stroke at a Japanese tertiary emergency hospital with a 24-h stroke team and care unit, we surveyed the presentations of patients with acute ischemic stroke or transient ischemic attack (TIA) seen within 7 days of onset. Delay from symptom onset to arrival at our hospital, from arrival to initial diagnostic brain computed tomography (CT), and the type of anti-thrombotic treatments were evaluated. During the 18-month period, there were 254 ischemic events in 244 patients; 239 (94%) had an ischemic stroke and 15 (6%) TIA. Eighty-two (32%) events presented within 3 h of onset, and 102 (40%) and 179 (70%) within the first 6 and 24 h, respectively. The median delay from hospital arrival to CT was 32 min, ranging 10 min to 22 h. Two hundred (79%) events underwent CT within 1 h of arrival (n=172) or at the referral hospitals before transfer (n=28). Direct ambulance transportation and more severe neurological deficits were independent predictors both for early arrival and short in-hospital delay to CT. Anti-thrombotic therapies including anticoagulant and/or antiplatelet medications were given in 237 (93%) episodes. Two (1%) patients received thrombolysis, although 18 (7%) patients fulfilled the National Institute of Neurological Disorders and Stroke guidelines for intravenous thrombolysis with tissue plasminogen activator. As in western communities, our pre-hospital emergency referral systems for acute stroke require substantial improvements including the wider use of ambulance calling. Although our in-hospital stroke management is functioning relatively well, further efforts are necessary in reducing the diagnostic delay.

Abstract
Stroke is an increasing cause of morbidity and mortality in Indonesia. Data on clinical patterns of hospitalized Indonesian stroke patients are still not available. This study is a part of ASNA (ASEAN Neurological Association) Stroke Epidemiological Stu dy aimed to investigate clinical profile of stroke in seven ASEAN countries with the same protocol. From 2065 acute stroke patients admitted to 28 hospitals all over Indonesia, the mean age was 58.8 (Standard Deviation [SD] 13.3) years (range: 18-95 year s). 12.9% were younger than 45 years, and 35.8% were older than 65 years. There were more men than women. Mean admission post-stroke time was 48.5 h (SD 98.8) (range: 1-968 h). Most of them arrived at hospital more than 6 h from stroke onset. The reasons for delayed admission were unawareness of stroke symptoms and long distance transportation. The most frequent stroke symptoms were motor disability. The most common risk factors were hypertension, heart disease, cigarette smoking and diabetes mellitus. Recurrent stroke was found in nearly 20% of patients. Ischemic stroke was the most frequent and the majority of the study subjects were discharged alive and improved.

Abstract
OBJECTIVE Tissue plasminogen activator (t-PA) has been approved by the Food and Drug Administration in the treatment of patients with acute ischaemic stroke presenting within three hours from onset of symptoms. This study aims to identify the potential number of stroke patients suitable for t-PA in Hong Kong. METHODS All patients with a clinical diagnosis of acute stroke were recruited. Data collected included demographics, vital signs, medical history, contraindications to thrombolysis, severity of stroke (Canadian neurological scale), time course from onset of symptoms to computed tomography, computed tomography results, and final diagnoses by physicians. RESULTS During the five month study period, 201 patients were recruited and nine were subsequently excluded from further analysis because computed tomography was not performed. Their mean age was 70.9 (range from 41-91) years. Eighty (41.7%) and 100 (52.1%) patients presented to our emergency department within two hours and three hours respectively from symptom onset. The mean severity score (Canadian neurological scale) was 7.83 (out of a maximum of 11.5). A total of 132 (68.8%) patients had acute ischaemic stroke confirmed by computed tomography. Mean delay in computed tomography was 4.91 hours. Fourteen (7.3%) and 52 (27.1%) of all patients had computed tomography of the brain done within one and two hours respectively. Only 20 patients (10.45%) could meet the three hour criteria as stated in the National Institute of Neurologic Disorders and Stroke rt-PA stroke study and seven (3.6%) of them were confirmed to have acute ischaemic stroke. Two patients were further excluded because of high systolic blood pressure and current warfarin medication. CONCLUSION At present very few patients could benefit from thrombolytic treatment. Delays in the chain of recovery in stroke management should be identified and corrected.

Abstract
OBJECTIVE To determine the magnitude of prehospital delay and how much time elapses between emergency department (ED) presentation and ED clinical investigations in ischemic stroke patients. Factors associated with prehospital delay were also correlated with demographic characteristics and clinical variables. METHODS A prospective, observational study was conducted simultaneously in five community teaching hospitals in Taiwan from October 1997 to April 1998. Included were all patients presenting with acute ischemic stroke. In each case, diagnosis was confirmed by cranial CT scanning. The main outcomes measured were the number of patients presenting at the ED more than two hours after the onset of symptoms (T(prehospital) > 2 hr) and the time spent at the ED for ED physician evaluation, cranial CT scanning, laboratory examinations, and neurologic consultation. Chi-square testing was used to compare the characteristics of patients with T(prehospital) > 2 hr and those with T(prehospital)< or = 2 hr. Independent predictors of T(prehospital) > 2 hr were determined using multiple logistic regression. RESULTS Of 157 patients observed, 105 (67%) arrived at the hospital more than 2 hr after the onset of symptoms. Average time from ED presentation to examination by ED physician, completion of CT scanning, and laboratory investigations was 3, 58, and 61 minutes, respectively. Mean time from ED presentation to neurologic consultation was 174 minutes for 38 patients [24%, (38/157)]. The factor associated with T(prehospital) > 2 hr was interhospital transfer (p < 0.05). CONCLUSION This study reveals that delayed management of stroke patients is mainly due to delayed ED presentation and to difficulties in obtaining neurologic consultation. Ideally, a stroke center may be incorporated within the EMS system to overcome delays due to interhospital transfer and to difficulties in obtaining neurologic consultation.

Abstract
STUDY OBJECTIVE To document prehospital and inhospital time intervals from stroke onset to emergency department evaluation and to identify factors associated with presentation to the ED within 3 hours of symptom onset, the current time window for thrombolytic therapy. METHODS Patients admitted through the ED with a diagnosis of stroke were identified through admitting logs. Time intervals were obtained from EMS runsheets and ED records. Information regarding first medical contact, education, and income was obtained by patient interview. Baseline variables were analyzed to assess association with ED arrival within 3 hours of symptom onset; variables significant on univariate analysis were placed in a multivariable model. RESULTS There were 151 stroke patients (59% white and 41% black). Time of stroke onset and time to ED arrival were documented for 119 patients (79%). The median time from stroke onset to ED arrival was 5.7 hours; 46 patients (30%) presenting within 3 hours. Of those with times recorded, the median time from stroke onset to EMS arrival was 1.7 hours. Multivariable logistic regression identified use of EMS (odds ratio [OR], 4.0; 95% confidence interval [CI], 1.3 to 12.1) and white race (OR, 3.5; 95% CI, 1.3 to 10) as being independently associated with ED arrival within 3 hours of symptom onset. Median time from ED arrival to physician evaluation was 20 minutes. Median time from ED arrival to computed tomographic evaluation was 72 minutes. When patients were asked the main reason they sought medical attention, 40% (60/141) of those able to be interviewed said that they themselves did not decide to seek medical attention, but rather a friend or family member told them they should go to the hospital. CONCLUSION The median time from stroke onset to ED evaluation was 5.7 hours, with almost a third of patients presenting within 3 hours. Use of EMS and white race were independently associated with arrival within 3 hours.

Abstract
BACKGROUND Intravenous use of tissue plasminogen activator (TPA) is the only currently approved treatment for acute ischemic stroke. METHODS To determine emergency physician attitudes and practices with regard to thrombolysis for ischemic stroke, a questionnaire was sent to program directors of accredited emergency medicine residencies in the United States. RESULTS There were 73 program directors who responded to the survey; 71% of medical centers have used TPA for treatment of stroke. The reported major complication rate for cerebral hemorrhage and death averaged 7%. For nontreating centers, two major factors cited were lack of appropriate patients and concerns regarding the safety of TPA; 48% of the facilities do not have an acute stroke team. Delayed patient arrival and the perceived narrow risk/benefit ratio of TPA were identified as the two greatest obstacles to more widespread use of TPA. CONCLUSION Although the majority of medical centers that responded in this study have some experience with thrombolytic therapy for acute ischemic stroke, almost one half do not have an acute stroke team and considerable uncertainty exists regarding the safety of intravenous TPA. More uniform national treatment of acute stroke will require greater consensus among emergency physicians and further analysis of the risk/benefit ratio of thrombolytic treatment.

Abstract
OBJECTIVE To assess the determinants of prehospital delay for patients with presumed acute cerebral ischemia (ACI) in order to provide the background necessary to develop interventions to shorten such delays. METHODS A prospective registry of patients presenting to the ED with signs and symptoms of stroke was established at a university hospital from July 1995 to March 1996. Trained nurses performed a structured ED interview, which assessed prehospital delay and potential confounders. RESULTS The median delay (interquartile range) from symptom onset to ED arrival for all patients seeking care for stroke-like symptoms (n = 152) was 3.0 hours (1.5-7.8 hr). The median delay from symptom onset to ED arrival was less in cases where a witness first recognized that there was a serious problem than it was when the patient first identified the problem. A heightened sense of urgency by the patient about his or her symptoms, and use of 911/emergency medical services (EMS) transport were also associated with rapid arrival in the ED within 3 hours of symptom onset. After adjusting for all predictor variables in a multivariable logistic regression model, only recognition of symptoms by a witness and calling 911/EMS transport remained statistically significant. CONCLUSIONS These data suggest that future efforts to intervene on prolonged prehospital delay for patients with ACI should include strategies for the community as a whole as well as persons at risk for stroke and should reinforce the use of 911 and EMS transport.

Abstract
The therapeutic window for efficient post-treatment of focal cerebral ischaemia with the fibrinogen lowering agent ancrod was studied by magnetic resonance imaging (MRI) in spontaneously hypertensive rats (SHR). Ancrod or vehicle solution (0.9% NaCl) were i.v. infused (0.12 IU/kg per min) via implanted mini pumps starting 0.5, 1.5, 3 or 6 h after permanent proximal middle cerebral artery occlusion and lasting until brain mapping by multislice T2-weighted magnetic resonance imaging in vivo 24 h after middle cerebral artery occlusion. Plasma fibrinogen concentrations were measured before middle cerebral artery occlusion, before pump implantation and after magnetic resonance imaging. Total brain lesion volumes as determined by magnetic resonance imaging 24 h after middle cerebral artery occlusion were 131 +/- 36 (188 +/- 28)*, 151 +/- 39 (194 +/- 39)*, 147 +/- 44 (207 +/- 33)* and 209 +/- 60 (214 +/- 42) mm3 in rats with 0.5, 1.5, 3 and 6 h, respectively, delay of ancrod treatment (means +/- S.D., 8-11 animals/group, corresponding control groups in parentheses, *P < 0.05). Continuous i.v. ancrod infusions reduced plasma fibrinogen levels significantly (P < 0.05) in all ancrod-treated groups as compared to vehicle-treated controls until the end of the experiments 24 h after middle cerebral artery occlusion. In conclusion, significant cerebroprotection was achieved even when the onset of ancrod therapy for lowering of the plasma fibrinogen level was delayed for up to 3 h. To the best of our knowledge no drug efficacy has been reported so far with a therapeutic window of 3 h after permanent middle cerebral artery occlusion in spontaneously hypertensive rats suggesting that ancrod may provide an efficient therapy of acute human stroke.

Abstract
Given the current orientation towards the early treatment of stroke, this multicenter study was carried out in North-east Italy in order to examine the times between stroke onset and hospital admission, and the possible factors leading to a lengthening of such times. An analysis was made of 348 patients, 79.8% of whom had experienced an ischemic cerebral infarct. Arrival times were not significantly modified by the distance from hospital, age, family cohabitation, socio-cultural level, population density or the geographical location of the Center. Sixty percent of the ischemic stroke cases arrived at the Emergency Department within three hours, and 80% within six hours; the hemorrhagic cases arrived earlier, 100% of them by the tenth hour. The duration of stay in the Emergency Department did not vary in relation to the severity or type of stroke. Greater severity, a reduced level of awareness and daytime onset led to a moderately significant reduction on presentation times. In conclusion, the majority of patients arrived sufficiently quickly to be treated within the "therapeutic window"; nevertheless, an information campaign may be useful in accelerating the hospital presentation of the albeit limited number of cases who arrive late.

Abstract
A few on-going international trials aim to investigate the effectiveness of early fibrinolytic treatment for ischaemic stroke to assist cerebral reperfusion. This operative strategy depends on clinical parameters such as haemorrhagic lesions, coma, pre-existent impairment and disability, and the efficiency of the sanitary organization receiving the patients (availability of CT scan, hospitalization within 6 h of onset of symptoms). We report data on the operative efficiency of a Regional Hospital Centre without a stroke unit: we observe that 142 patients did not receive early stroke treatment because of organizational problems whose prevalence exceeded the incidence of theoretical contraindications to fibrinolytic use. These elements suggest the necessity to organize a specific ward for the management of acute stroke.
