INTRODUCTION: Stroke is a leading cause of death and disability. Patients with suspected stroke are usually managed in emergency departments (ED). Stroke units must be created in our country, but only few French epidemiological data are available to define needs in stroke care. OBJECTIVE: A prospective study was planned to evaluate epidemiology and stroke care for patients with suspected stroke admitted in the 22 ED of our region in the center of France during a two-month period. METHODS: Patients with suspected stroke seen at the 22 ED were prospectively followed until discharge or one month after admission. Data on demographic characteristics, mode of transport, delay of arrival and imaging, clinical findings at arrival, department of admission, diagnosis, Rankin scale at day 7, in-hospital mortality, and outcome at a month were collected. A global statistical analysis and a comparison between rural and urban ED were performed. RESULTS: Five hundred and ninety-eight patients were included. Mean age was 75 years. Median admission delay was 4 hours and 52 minutes. Predominant mode of transport was a private ambulance. A CT scan was obtained in 91 p.cent of cases with a median delay of 2 hours and 30 minutes. Only a third of the patients were admitted in departments of Neurology. Final diagnosis was: ischemic stroke (61 p.cent), transient ischemic attack (16 p.cent), hemorrhagic stroke (10 p.cent), other vascular disease (3 p.cent), non vascular disease (10 p.cent). In-hospital mortality was 20 p.cent, factors significantly associated with death rate were elevated age and a Glasgow coma scale<10 at admission. Mean length of stay was 12 days for stroke patients. At one month, 63 percent of patients were discharged to their home, 28 percent were transferred to an institution or in a rehabilitation unit, and 15 percent were still hospitalized. Significant differences in stroke care were found between rural and urban ED. CONCLUSION: This prospective study provides epidemiological data for our region. Creation of stroke units and definition of acute stroke networks are necessary to improve stroke care. 相似文献

The purpose of this study is to identify which factors are able to limit or hamper the access to systemic thrombolysis (evTPA) in Lombardia to define corrective interventions. We analyzed 1,015 patients with ischemic stroke admitted to emergency departments (ED) participating to the Lombardia Stroke Unit Registry and eligible for evTPA; 303 (29.9 %) patients were treated with evTPA (evTPA+ group) and 712 (70.1 %) were not (evTPA? group). We collected case-mix and stroke care process variables.The evTPA+ group was characterized by a shorter ED arrival time, a greater neurological impairment, a more chance to be admitted to ED linked to comprehensive stroke center (CSC) and a shorter waiting time to access to diagnostic procedures. The chance to be treated with evTPA was greater if neurological evaluation anticipated neuroimaging (p = 0.0003). The multivariate analysis confirmed that the admission to ED linked to CSC (OR: 2.50, 95 % CI: 1.39–4.48, p < 0.0001) and neurological evaluation performed before neuroimaging (OR: 2.34, 95 % CI: 1.35–4.04, p = 0.002) increased the probability to receive rtPA. The evTPA treatment is strictly dependent on pre-hospital and ED care process phases and strongly influenced by the degree of stroke severity. Door-to-needle time is shorter in patients with a greater stroke severity and a shorter ED arrival time. A 24-h/week availability of the neurologist in ED can increase the percentage of thrombolysis optimizing the selection of patients and the timing of the diagnostic procedures. 相似文献

Objectives – To determine the proportion of patients with an ischemic stroke that received intravenous (IV) thrombolytic treatment, and reasons why patients are not treated. Methods – A prospective registry of all patients with an ischemic stroke admitted to our emergency department (ED). Results – A total of 286 patients with an ischemic stroke were admitted. Eighty‐one patients were admitted within 3 h of onset of neurological deficit, of which 28 received IV thrombolysis. In 25 patients no thrombolytic treatment was given because of the presence of the National Institute of Neurological Disorders and Stroke (NINDS) exclusion criteria, and one patient refused treatment. No thrombolytic treatment was given to 27 patients because of mild neurological deficit or rapid clinical improvement, and after 3 months all these patients were independently living at home without nursing help. Despite a public campaign to gain awareness concerning stroke, the majority of the patients arrived too late at the ED for thrombolytic treatment. Conclusions – A large proportion of the patients with an ischemic stroke are admitted too late to receive IV thrombolysis. More needs to be done to increase both public and medical awareness of stroke as a treatable emergency. 相似文献

After recognizing the pivotal role played by stroke unit (SU) admission in reducing mortality and dependency in stroke patients, the need to organize and monitor stroke networks has become an increasingly essential aspect of stroke care. We conducted a retrospective study of stroke patients admitted to hospitals in the Veneto region from 2007 to 2015 in order to evaluate the effectiveness of the stroke pathway and trends over time. Between 2007 and 2015, 61,062 stroke patients were discharged from Veneto hospitals: they were more frequently female, females were older than males, and had higher intrahospital mortality and a lower probability of undergoing systemic thrombolysis. Patients admitted to facilities with a level 2 SU were twice as likely to undergo thrombolytic treatment compared to those admitted to facilities with a level 1 and had a lower intrahospital mortality rate. During the collection period, thrombolytic treatments increased in both level 1 and 2 SUs, as did the number of patients admitted to neurology wards and to facilities with an SU. Our study confirmed that thrombolytic treatment and admission to a facility with an SU are important determinants in improving stroke patient outcome. The increase in the proportion of both SU admissions and thrombolytic treatments demonstrates the effectiveness of the regional hub-and-spoke organization model, suggesting that implementation of highly specialized facilities is an efficient strategy in improving stroke care. The role of the observed sex bias in stroke treatment and outcome needs to be explored. 相似文献

We determined the factors leading to emergency department (ED) delays in patients with acute stroke. Data were collected prospectively in four Berlin inner-city hospitals by ED documentation, medical records, imaging files and patient interviews. An extended Cox proportional hazards model was fitted to the data. Analyses were performed in 558 patients with confirmed diagnosis of stroke. Median time from admission at ED to beginning of computed tomography/magnetic resonance imaging (CT/MRI) was 108 min. In a subgroup of patients potentially eligible for thrombolysis with a pre-hospital delay <120 min and a National Institutes of Health Stroke Scale (NIHSS) >4 (n = 74), the median interval to imaging was 68 min. Multivariable analysis revealed that a more severe initial NIHSS, a pre-hospital delay <3 h, admission at two specific hospitals, admission at weekends, and private health insurance were significantly associated with reduced delays. In stroke patients, the time interval between ED admission and imaging depends both on factors that emerge from clinical needs and on factors independent of clinical necessities. Considering the urgency of therapeutic measures in acute stroke, there is necessity and room for both improvement of in-hospital management and of medical and non-medical factors influencing pre-hospital delays. 相似文献

OBJECTIVE: Barriers to thrombolysis are rather assessed for hospitalized stroke patients than among geographically defined populations. In a population-based approach, we assessed (1) the utilization rate of stroke thrombolysis in the community, and (2) the significance of the chosen stroke care provider as a potential barrier to thrombolysis. METHODS: We performed a databank-based post-hoc analysis, derived from data ascertained in a prospective, population-based stroke study among the permanent residents of the canton Basel-City, Switzerland. For the cohort with an onset assessment interval (OAI) < or =3 h, we compared thrombolyzed with non-thrombolyzed patients concerning demographic variables, the National Institutes of Health stroke scale (NIHSS) score, OAI, risk factors, and the type of stroke care provider. For patients without thrombolysis despite an OAI < or =3 h, barriers to thrombolysis were compiled. RESULTS: Among 269 patients, 49 had an OAI < or =3 h (18% of all patients and 38% of those 128 patients with exactly known time of onset). Fourteen patients received thrombolysis, amounting to a utilization rate of 5.2% (95% CI 2.9-8.6) for all patients and 29% (95% CI 17-43) for the OAI < or =3-hour cohort. For the latter, thrombolyzed differed from non-thrombolyzed patients in higher NIHSS score and type of stroke care provider, but not in demographic variables, OAI, or risk factors. Fourteen of 40 patients (35%) primarily admitted to the stroke unit received thrombolysis, compared with none of 9 patients primarily treated elsewhere (p < 0.04). In the OAI < or =3-hour cohort, mild or regressing stroke severity (48%), admission to hospitals not offering thrombolysis (20%), computed tomography or laboratory contraindications (17%) and severe comorbidity (14%) were barriers to thrombolysis. CONCLUSION: In this geographically defined population, every 20th stroke patient received thrombolysis. Only a minority of patients had an OAI < or =3 h, rendering late admission the most common barrier to thrombolysis. In the OAI < or =3-hour cohort, admission to hospitals not offering thrombolysis prompted exclusion from thrombolysis as often as established contraindications. Thus, acute stroke patients should solely be brought to hospitals providing thrombolysis. 相似文献

OBJECTIVES: We have shown that a Breakthrough Series-based implementation program increases the number of patients with acute ischemic stroke treated with alteplase 4.5% in real-life settings. It is unclear whether such an implementation program is cost-effective. METHODS: The practice study includes 12 randomized hospitals and 5,515 patients. Its present cost-effectiveness analysis involves 1,657 patients with ischemic stroke admitted within 4 hours from onset. Defined primary outcomes are thrombolysis rate and actual health care costs up to 3 months, including additional implementation efforts. Secondary outcomes are lifetime quality-adjusted years (QALYs) and lifetime costs of individual trial patients, using a validated probabilistic, disability-stratified stroke life table. Differences in outcome include 95% confidence intervals (CI), adjusted for intracluster correlation. RESULTS: The thrombolysis rate in the intervention group was 44.3% vs 39.8% in the control group (difference 4.5%; 95% CI 3.1% to 5.9%. Mean costs per patient at 3 months (euros were converted to 2010 USD) were $9,192 USD in the intervention group and $9,647 USD in the control group (difference -$455 USD; 95% CI -$232 to -$679 USD). Lifetime QALYs in the intervention group were 3.89 and in the control group 3.84 (difference 0.05; 95% CI -0.04 to 0.14). The mean lifetime costs in the intervention group were $22,994 USD against $24,315 USD in the control group (difference -$1,321 USD; 95% CI -$1,722 to -$921 USD). CONCLUSIONS: A Breakthrough Series implementation program of thrombolysis increases thrombolysis. It saves short- and long-term health care costs due to lower hospital admission and residential costs, increasing stroke care efficiency. 相似文献

Background:
Acute management of ischemic stroke involves thrombolysis within 4.5 h. For a successful outcome, early recognition of stroke, transportation to the hospital emergency department immediately after stroke, timely imaging, proper diagnosis, and thrombolysis within 4.5 h is of paramount importance.Aim:
To analyze the obstacles for thrombolysis in acute stroke patients.Materials and Methods:
The study was conducted in a tertiary care center in South India. A total of hundred consecutive patients of acute ischemic stroke who were not thrombolysed, but otherwise fulfilled the criteria for thrombolysis were evaluated prospectively for various factors that prevented thrombolysis. The constraints to thrombolysis were categorized into: i) Failure of patient to recognize stroke symptoms, ii) patient''s awareness of thrombolysis as a treatment modality for stroke, iii) failure of patient''s relative to recognize stroke, iv) failure of primary care physician to recognize stroke, v) transport delays, vi) lack of neuroimaging and thrombolysis facility, and vii) nonaffordability.Results:
The biggest hurdle for early hospital presentation is failure of patients to recognize stroke (73%), followed by lack of neuroimaging facility (58%), nonaffordability (56%), failure of patient''s relative to recognize stroke (38%), failure of the primary care physician to recognize stroke (21%), and transport problems (13%). Awareness of thrombolysis as a treatment modality for stroke was seen only in 2%.Conclusion:
Considering the urgency of therapeutic measures in acute stroke, there is necessity and room for improvement to overcome various hurdles that prevent thrombolysis. 相似文献10.

BACKGROUND AND PURPOSE: Use of thrombolysis and acute treatments for cerebral infarction may require that acute stroke be treated as a medical emergency. To assess the factors influencing the time to admission in acute stroke, we conducted a prospective study of all such patients admitted to the hospitals in Leicester, UK, over a 12-month period. METHODS: Factors assessed were age, sex, time of stroke onset, stroke severity, home circumstances, and routes of admission. Initial between-group comparisons were made with the Mann-Whitney U test. The individual contribution of each of these variables was assessed with multiple linear regression analysis. RESULTS: An accurate time of stroke onset was identified in 374 (70%) of 535 registered patients (median age 77 [range, 29-98] years; 332 men, 203 women). Median time from onset to admission was 6 hours, with 25% of the patients arriving in less than 2.5 hours and 75% in less than 11.5 hours. Multiple regression confirmed that only admission through the bed allocation bureau (p less than 0.001), living alone (p less than 0.001), and nocturnal onset (p = 0.003) prolonged delay time. Despite patients over 70 years of age taking a median of 7 hours from onset to admission compared with 4 hours for those under age 70 (p less than 0.001), the effect of age appeared to be dependent on these three factors. Age, sex, level of consciousness, rural domicile, and place of admission did not influence the delay time independently. CONCLUSIONS: We have identified some of the factors affecting the hospital admission delay time for stroke. With the possible advent of effective early treatments for stroke, these factors will need to be addressed. 相似文献

OBJECTIVE: To evaluate the impact that monitored acute stroke unit care may have on the risk of early neurological deterioration (END), and 90-day mortality and mortality-disability. METHODS: Non-randomized prospective study with consecutive patients with acute ischemic stroke (AIS) admitted to a conventional care stroke unit (CCSU), from May 2003 to April 2005, or to a monitored acute stroke unit (ASU) from May 2005 to April 2006. END was defined as an increase in the NIHSS score >or= 4 points in the first 72 hours after admission. RESULTS: END was detected in 19.6% of patients (11.2% of patients admitted to the ASU and 23.8% to the CCSU; p<0.0001). Patients admitted to the ASU received more treatment with intravenous rtPa (13.5% versus 4.2%; p<0.0001), had a shorter length of stay (9.1 [11.0] d versus 13.1 [10.4] d; p<0.0001), lower 90-day mortality (10.2% versus 17.3%; p=0.02), and lower mortality-disability at 90-days (28.4% versus 40.2%; p=0.004) than those admitted to the CCSU. Multivariable analysis showed that ASU admission was a protector for END (OR: 0.37; 95% CI: 0.23-0.62). On admission, higher NIHSS (OR: 1.06; 95% CI: 1.03-1.10), higher glycaemia (OR: 1.003; 95% CI: 1.001-1.006), and higher systolic pressure (OR: 1.01; 95% CI: 1.002-1.017) were independent predictors of END. CONCLUSIONS: END prevention by ASU care might be a key factor contributing to better outcome and decrease of length of stay in patients admitted to monitored stroke units. 相似文献

Early recognition of stroke symptoms and activation of emergency medical service (EMS) positively affects prognosis after a stroke. To assess stroke awareness among stroke patients and medical personnel in the catchment area of Verona Hospital and how it affects stroke care, we prospectively studied timing of acute stroke care in relation to patients’ characteristics. Patients admitted to Medical Departments of Verona University Hospital between January 1st and December 31st 2009 with a diagnosis of TIA or stroke were enrolled. Outcome measures were: time between (i) symptoms onset and hospital arrival, (ii) hospital arrival and brain CT scan, blood examination, ECG and neurological evaluation. The following patient/event characteristics were also collected: means of hospital arrival, sex, age, degree of disability, type of event (first or recurrent) and acute-phase treatment. Of 578 patients providing complete information, 60 % arrived to the emergency department with the EMS (EMS+ group), while 40 % arrived on their own (EMS?). EMS+ group was older than EMS? (mean age 76.2, SD 13.2, vs. 72.3, SD 13, respectively), displayed more severe symptoms (mRS 4 vs. 2) and shorter time interval between symptoms onset and hospital arrival, hospital arrival and CT scan, ECG, laboratory tests and neurological evaluation (p < 0.0001); 22 % of the EMS+ patients were stroke recurrences versus 29 % of the EMS? (p = 0.058); 85 % of thrombolised patients were EMS+. We conclude that there is a lack of awareness of stroke symptoms and risks of recurrence even among patients who already had a stroke and among medical personnel. 相似文献

Background and purpose: We compared characteristics and treatment success of ischaemic stroke patients admitted during daytime on working days (office hours) with patients admitted on weekend or nighttime (non-office hours) to test if differences in presentation or restraints of medical care during non-office hours determine outcome in stroke patients.
Methods: We analyzed a prospective stroke registry and grouped patients according to admission on office hours and non-office hours. Clinical state on admission, risk factors, sociodemographic items, complications, place of discharge, and clinical state on discharge were recorded.
Results: A total of 37 396 stroke patients were evaluated. Onset–admission time on Monday was significantly elevated and on weekend significantly reduced. Number of patients with treatment success did not differ between patient groups whilst mortality within 7 days, proportion of embolic stroke, overall mortality and rate of complications where higher in patients admitted during non-office hours, rate of thrombolytic treatment was significantly higher during non-office hours. After adjustment for clinical state and admission latency, risk for severe outcome or death was independent from time of admission.
Conclusion: Considering the fact that stroke patients admitted during non-office hours were in more severe clinical condition we found no differences in outcome. Fear of impaired access to sophisticated treatment options during non-office hours could be dispelled by the fact, that rate of thrombolytic treatment was even higher during night and weekend. Therefore, our data do not confirm a weekend effect or night effect on stroke treatment. Delay in request of medical care of mildly affected patients that suffer from stroke on weekends confirms need for educational efforts. 相似文献

BACKGROUND: The aim of this study was to assess the feasibility, clinical effect and safety of intravenous thrombolysis with tissue plasminogen activator in patients with acute ischaemic stroke treated in an acute stroke unit. METHODS: All patients admitted within 3 h after an acute ischaemic stroke were considered for thrombolysis. Twenty-four patients were treated. RESULTS: Ten patients demonstrated early clinical improvement compatible with a positive effect of thrombolysis. Five patients demonstrated a substantial but slow clinical improvement with an uncertain relationship to thrombolysis. Nine patients did not improve. One patient developed an intracerebral haematoma and 2 developed a haemorrhagic infarction without clinical deterioration. Five patients (21%) died within the first 3 months. At follow-up after 6 months, 10 patients (42%) had achieved independence [modified Rankin Scale (mRS) 0-2], 9 (33%) had an unfavourable outcome (mRS 3-5) and 5 patients (21%) had died. None of these 5 patients died due to a treatment complication. CONCLUSIONS: This study in a small patient population suggests that thrombolysis may be administered relatively safely in an acute stroke unit without intensive care facilities. The clinical effect and safety were similar to those which have been found in large randomised studies and clinical series. 相似文献

AIMS: We studied whether baseline body temperature and temperature increases after stroke adversely affect outcome after thrombolysis with intravenous tissue plasminogen activator (IV tPA). METHODS: The evolution of body temperature in the first 24 h after treatment with IV tPA was described by calculating the area under the curve of the temperature over time plot relative to temperature at admission (AUCBL) and relative to a standard value of 37 degrees C (AUC37). Temperature parameters were related to functional outcome. RESULTS: The median baseline National Institutes of Health Stroke Scale of 100 consecutive patients was 16 (interquartile range 11-21) and 34 patients had a favourable response to tPA. Patients with an unfavourable outcome had a more important temperature elevation than patients who had a favourable outcome after tPA (+1 degrees C vs +0.6 degrees C, P=0.02), despite similar baseline T and had a higher AUCBL (9.79 vs 5.36, P=0.027) and more frequently showed hyperthermia relative to baseline (82% vs 56%, P=0.011). After adjustment for baseline characteristics, the presence of hyperthermia relative to baseline was associated with a reduced odds of good outcome after thrombolysis (OR 0.34, 95% CI 0.10-0.95, P=0.040). CONCLUSION: Hyperthermia relative to baseline temperature in the 24 h after intravenous thrombolysis is associated with an unfavourable outcome. 相似文献

Background: Since doubts were raised, if a challenging medical procedure such as acute stroke treatment including thrombolysis with recombinant tissue plasminogen activator (rTPA) is available with identical standard and outcome 24 h and 7 days a week our aim was to examine if acute stroke patients defined by onset‐admission time (OAT) of ≤ 3 h were treated differently or had distinct outcome when admitted during off duty hours (day versus night and weekend versus weekdays) and if any differences in treatment or outcome were apparent when comparing patients admitted in the year 2003 with patients admitted in the year 2006. Methods: We analyzed 2003–2006 data of a prospective registry and grouped patients by time, day, and year of admission. The evaluation was limited to patients that were diagnosed with ischaemic stroke and with OAT of ≤ 3 h. Medical and sociodemographic items, use of thrombolytic treatment, complications during clinical course and place of discharge were obtained. Clinical state on admission and discharge was assessed using the modified Rankin scale. Comparison with chi‐square test, t‐test and logistic regression was performed. Results: Patient’s characteristics, rate of thrombolysis, and outcome were independent from time or day of admission. Proportion of patients with good clinical state at discharge increased significantly from 2003 to 2006 together with a higher rate of rTPA treatment without increase of intracranial hemorrhage. Proportion of patients discharged in good clinical condition after rTPA treatment increased from 34% to 44%. Conclusions: Stroke treatment in potential candidates for thrombolytic therapy revealed no impairment on weekend or at night already in 2003. During 4 years, it was possible to increase rate of rTPA treatment from 8.9% to 21.8% without increment of complications or death, confirming that rTPA is safe and can be implemented with full daily and weekly coverage. 相似文献

Background and purpose: We assessed the safety and efficacy of intravenous thrombolysis (IVT) in acute stroke patients with hyperdense middle cerebral artery sign (HMCAS).
Patients and methods: Data from consecutive patients with acute (within 6 h of symptom onset) ischaemic stroke admitted between January 1999 and November 2007, in whom HMCAS was diagnosed on admission CT scan was retrospectively analysed. Seventy-one patients, admitted within the 3-h window, were treated with IVT, whilst further 42, admitted 3–6 h after symptom onset, were not. At 3-month clinical follow-up, outcome, mortality at 3 months and incidence of symptomatic intracranial haemorrhage were evaluated.
Results: The two groups were comparable concerning age, stroke risk factors, prior antithrombotic treatment and NIHSS scores on admission. Good outcome (mRS score ≤ 1) was observed in 12/71 (17%) patients who were treated with IVT and in 1/42 (2%) patients who were not ( P = 0.02). IVT treatment was identified as independent predictor of good outcome ( P = 0.05). Mortality was 20% in patients treated with IVT and 12% in remaining patients ( P = 0.3). Symptomatic intracranial haemorrhage occurred in 1 patient of each group (2%).
Conclusions: These findings suggest that IVT in patients with HMCAS results in significantly better outcome, without significantly influencing mortality. 相似文献

Do transient ischemic attacks have a neuroprotective effect? 总被引:82,自引:0,他引:82
OBJECTIVE: To determine whether TIAs have a neuroprotective effect. BACKGROUND: Ischemic tolerance or preconditioning, which protects the brain against stroke, has been demonstrated in animal models of cerebral ischemia. Because TIA may represent a clinical model of ischemic tolerance, patients with TIA before cerebral infarction (CI) may therefore have a better outcome than patients without TIA before CI. METHODS: A total of 2,490 patients admitted consecutively to a primary care center for first-ever CI in the anterior circulation were divided into two groups on the basis of the presence or absence of prior ipsilateral TIAs. Duration of TIA was classified into three groups (<10 minutes, 10 to 20 minutes, and >20 minutes). The severity of the neurologic picture on admission and functional disability after stroke were compared between patients with and without TIAs. RESULTS: A total of 293 (12%) of the 2,490 patients had prior ipsilateral TIAs before CI. Risk factors did not differ between patients with or without TIAs, whereas the topography and etiology of ischemic stroke did differ (p < 0.001). Patients without prior TIAs had a more severe clinical picture on admission, with a greater reduction of consciousness (p = 0.009). Patients with previous TIAs had a more favorable outcome than those without TIAs (67% versus 58%, p = 0.004). After adjustment for confounding variables, TIAs lasting 10 to 20 minutes were still associated with a favorable outcome (odds ratio, 1.98; 95% confidence interval, 1.27 to 3.08; p = 0.002). The interval between TIA and CI influenced the outcome (p = 0.007). CONCLUSIONS: This study suggests that ischemic tolerance may play a role in patients with ipsilateral TIAs before CI, allowing better recovery from a subsequent ischemic stroke. 相似文献

Referral from other hospitals is one of the primary causes of delayed thrombolysis therapy after acute ischemic stroke (AIS). We aimed to evaluate whether direct access to a hospital offering intravenous thrombolysis therapy was associated with good functional outcome in AIS patients treated with thrombolysis. We enrolled patients who received intravenous thrombolysis within 3 hours of symptom onset at our stroke center. We divided these patients into two groups: those with a direct admission to our stroke center and those with indirect admission by referral from other community hospitals. We investigated onset-to-door time and onset-to-recombinant tissue plasminogen activator (rtPA) time according to admission mode. We then assessed the association between a direct admission and favorable outcome at 90 days. A total of 232 patients (mean age of 66.6 years, median National Institutes of Health Stroke Scale score of 10) were included. A total of 48.7% of AIS patients treated with intravenous thrombolytic therapy were transferred from other hospitals. Patients who were directly admitted to our stroke center had a shorter onset-to-door time (61 versus 120 minutes, p < 0.001) and onset-to-rtPA time (103 versus 155 minutes, p < 0.001) than those referred from other hospitals. Direct admission was associated with a good outcome with an odds ratio of 2.03 (95% confidence interval 1.051–3.917, p = 0.035), after adjusting for baseline variables. Thrombolysis after direct admission to a hospital offering intravenous thrombolysis therapy could shorten onset-to-rtPA time and improve stroke outcome in patients with AIS. 相似文献

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. 相似文献
