Abstract
INTRODUCTION Time plays a crucial role in the management of stroke, and changing the prehospital emergency network, altering the HUB and spoke relationship in pandemic scenarios, might have an impact on time to fibrinolysis or thrombectomy. The aim of this study was to evaluate the time-dependent stroke emergency network in Lombardy region (Italy) by comparing 2019 with 2020 and early 2021. Three parameters were investigated: (i) time of arrival of the first vehicle at the scene, (ii) overall duration of missions, and (iii) number of patients transported by emergency vehicles. METHODS Data analysis process conducted using the SAS-AREU portal (SAS Institute, USA). RESULTS The number of patients with a positive CPSS was similar among the different pandemic waves. Mission duration increased from a mean time (SD) of 52.9 (16.1) min in 2019 to 64.1 (19.7) in 2020 and 55.0 (16.8) in 2021. Time to first vehicle on scene increased to 15.7 (8.4) min in 2020 and 16.0 (7.0) in 2021 compared to 2019, 13.6 (7.2) (P < 0.05). The number of hospital with available stroke units decreased from 46 in 2019 to 10 during the first pandemic wave. CONCLUSIONS The pandemic forced changes in the clinical mission of many hospitals by reducing the number of stroke units. Despite this, the organization of the emergency system allowed to identify strategic hospitals and thus avoid excessive transport time. The result was an adequate time for fibrinolysis/thrombectomy, in agreement with the guidelines. Coordinated management in emergency situations makes it possible to maintain service quality standards, despite the unfavorable scenario.

Associations between emergency call stroke triage and pre-hospital delay, primary hospital admission, and acute reperfusion treatment among early comers with acute ischemic stroke. Intern Emerg Med 2023; 18:2355-2365. [PMID: 37369888 PMCID: PMC10635938 DOI: 10.1007/s11739-023-03349-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/12/2023] [Accepted: 06/14/2023] [Indexed: 06/29/2023]
Abstract
To investigate the association between the Emergency Medical Service dispatcher's initial stroke triage and prehospital stroke management, primary admission to hospitals offering revascularization treatment, prehospital time delay, and rate of acute revascularization. In an observational cohort study, patients with acute ischemic stroke (AIS) in Denmark (2017-2018) were included if the emergency call to the Emergency Medical Dispatch Center (EMDC) was made within three hours after symptom onset. Among 3546 included AIS patients, the EMS dispatcher identified 74.6% (95% confidence interval (CI) 73.1-76.0) correctly as stroke. EMS dispatcher stroke recognition was associated with a higher rate of primary admission to a hospital offering revascularization treatment (85.8 versus 74.5%); producing an adjusted risk difference (RD) of 11.1% (95% CI 7.8; 14.3) and a higher rate of revascularization treatment (49.6 versus 41.6%) with an adjusted RD of 8.4% (95% CI 4.6; 12.2). We adjusted for sex, age, previous stroke or transient ischemic attack, and stroke severity. EMDC stroke recognition was associated with shorter prehospital delay. For all AIS patients, the adjusted difference was - 33.2 min (95% CI - 44.4; - 22.0). Among patients receiving acute revascularization treatment (n = 1687), the adjusted difference was -12.6 min (95% CI - 18.9; - 6.3). Stroke recognition by the EMS dispatcher was associated with a higher probability of primary admission to a hospital offering acute stroke treatment, and subsequently with a higher rate of acute revascularization treatment, and with an overall reduction in prehospital delay.

Abstract
BACKGROUND AND AIM The pre-hospital management of a possible stroke is fundamental for the transport of patients to the correct HUB facility; thus, they must be transported to the Emergency Department (ED) by EMS vehicles. Our study aims to analyze the factors correlated with a higher probability of accessing the ED through the EMS in this event. METHODS This is a retrospective observational study. All accesses in the 120 EDs of the Lombardy region, with a diagnosis of discharge whose symptoms could resemble CPSS, were analyzed between 1 January 2019 and 31 December 2019. RESULTS We identified an increased probability of using the EMS vehicles of 0,05% (I.C. 95%: 0.04% - 0.06%; p<0.0001) for each additional year of age, considering patients aged 20 to 100 years and the percentage was significantly higher in the female population (58% vs 49%; p<0.001). Moreover, we calculated that the incidence of stroke was approximately 140 cases per 100,000 inhabitants. CONCLUSIONS Only half of the citizens in the Lombardy region use the EMS in case of suspicion of stroke; further information campaigns are essential to educate citizens. Information strategies should be directed especially at men between 30 and 59 years old.

Abstract
Background The prognosis of stroke patients can be improved by adherence to clinical guidelines. Objective To analyse the current state of organisation of prehospital stroke treatment in Germany, Austria and Switzerland with a focus on guideline adherence. Materials and methods All medical directors of emergency medical services (MDEMS) in Germany (n = 178), Austria (n = 9) and Switzerland (n = 32) were invited to complete an anonymous online survey (unipark.com, Tivian XI GmbH, Cologne, Germany) which was available for 10 weeks from April-June 2020. Participants were asked for information regarding structural organisation, clinical treatment and strategic/tactical aspects. Results The survey was completed 69 times and 65 datasets were analysed (4 participants without MDEMS status): 73.8% (n = 48) were MDEMS from Germany, 15.4% (n = 10) from Switzerland and 10.8% from Austria (n = 7). The survey results show relevant differences in the infrastructure of and the approach to prehospital stroke treatment. Standard operating procedures for stroke treatment were in place in 93.3% (n = 61) of the EMS areas. Furthermore, 37% (n = 24) of the EMS areas differentiated between stroke with mild and severe symptoms and 15.4% (n = 10) used specific scores for the prehospital prediction of large vessel occlusion strokes (LVOS). Conclusions Our data highlight the heterogeneity of prehospital stroke treatment in Germany, Austria and Switzerland. Consistent use of appropriate scores for LVOS prediction and a higher adherence to recent clinical guideline in general are measures that should be taken to optimise the prehospital treatment of stroke patients.

Prehospital Translation of Chest Pain Tools (RESCUE Study): Completion Rate and Inter-rater Reliability. West J Emerg Med 2022; 23:222-228. [PMID: 35302456 PMCID: PMC8967468 DOI: 10.5811/westjem.2021.9.52325] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2021] [Accepted: 09/20/2021] [Indexed: 02/01/2023] Open
Abstract
INTRODUCTION Chest pain is a common reason for ambulance transport. Acute coronary syndrome (ACS) and pulmonary embolism (PE) risk assessments, such as history, electrocardiogram, age, risk factors (HEAR); Emergency Department Assessment of Chest Pain Score (EDACS); Pulmonary Embolism Rule-out Criteria (PERC); and revised Geneva score, are well validated for emergency department (ED) use but have not been translated to the prehospital setting. The objectives of this study were to evaluate the 1) prehospital completion rate and 2) inter-rater reliability of chest pain risk assessments. METHODS We conducted a prospective observational cohort study in two emergency medical services (EMS) agencies (April 18, 2018 - January 2, 2019). Adults with acute, non-traumatic chest pain without ST-elevation myocardial infarction or unstable vital signs were accrued. Paramedics were trained to use the HEAR, EDACS, PERC, and revised Geneva score assessments. A subset of patients (a priori goal of N = 250) also had the four risk assessments completed by their treating clinicians in the ED, who were blinded to the EMS risk assessments. Outcomes were 1) risk assessments completion rate and 2) inter-rater reliability between EMS and ED assessments. An a priori goal for completion rate was set as >75%. We computed kappa with corresponding 95% confidence intervals (CI) for each risk assessment as a measure of inter-rater reliability. Acceptable agreement was defined a priori as kappa ≥ 0.60. RESULTS During the study period, 837 patients with acute chest pain were accrued. The median age was 54 years, interquartile range 43-66, with 53% female and 51% Black. Completion rates for each risk assessment were above goal: the HEAR score was completed on 95.1% (796/837), EDACS on 92.0% (770/837), PERC on 89.4% (748/837), and revised Geneva score on 90.7% (759/837) of patients. We assessed agreement in a subgroup of 260 patients. The HEAR score had a kappa of 0.51 (95% CI, 0.41-0.61); EDACS was 0.60 (95% CI, 0.49-0.72); PERC was 0.71 (95% CI, 0.61-0.81); and revised Geneva score was 0.51 (95% CI, 0.39-0.62). CONCLUSION The completion rate of risk assessments for ACS and PE was high for prehospital field personnel. The PERC and EDACS both demonstrated acceptable agreement between paramedics and clinicians in the ED, although assessments with better agreement are likely needed.

Abstract
Objectives: Stroke burden is especially heavy in northeast China. Facilities with the capacity to perform acute reperfusion therapies for stroke are unevenly dispersed and are especially inadequate in rural areas. The aim of this study was to establish an effective measure to improve stroke emergency care, eventually increasing the capacity for reperfusion therapy in Jilin province, a less developed province in northeast China. Methods: We created the Jilin province Stroke Emergency Maps (JSEM), a regional stroke emergency network. Qualified hospitals in Jilin province were integrated into JSEM according to strict inclusion criteria. With constant evaluation and screening, more qualified hospitals may be enrolled into the JSEM, which is updated and published once per year. Locations of hospitals with the capacity to perform intravenous thrombolysis and emergency mechanical thrombectomy were labeled on the map. Results: After strict evaluation and screening, 19 designated hospitals were integrated into the JSEM in August 2017 (baseline). Following the implementation of the JSEM, 21 more designated hospitals (40 in all) were included in 2018, and 48 more designated hospitals were included in 2019. With the guidance of the JSEM, the rate of intravenous thrombolysis in Jilin province increased remarkably from 3.3% (2017, baseline) and 4.6% (2018) to 5.5% (2019). Mean door-to-needle time decreased from 62 min at baseline (2017) to 45 min 2 years later. The number of mechanical thrombectomy was increased from 457 at baseline (2017) to 749 (2018) and 1,137 (2019) per year, respectively, and mean door-to-puncture time was shortened from 136 to 120 min. Conclusion: The JSEM, a regional stroke emergency network, serves to improve patient care for stroke. The map's publication increased rates of intravenous thrombolysis and mechanical thrombectomy. JSEM effectively connected more qualified designated hospitals, stroke patients and emergency medical service systems in Jilin province.

Abstract
INTRODUCTION Since approval by the United States Food and Drug Administration in 1996, alteplase utilization rates for acute ischemic stroke have increased. Despite its efficacy for improving stroke outcomes, however, the majority of ischemic stroke patients still do not receive alteplase. To address this issue, different methods for improving access to alteplase have been tested with varying degrees of success. AREAS COVERED This article gives an overview of the recent approaches pursued to improve access to alteplase for acute ischemic stroke patients. Utilization of stroke systems of care, quality metrics, and quality-improvement initiatives to improve alteplase treatment rates are discussed. The implementation of Telestroke networks to improve access and timely evaluation by a stroke specialist are also reviewed. Lastly, this review discusses the use of neuroimaging techniques to identify alteplase candidates in stroke of unknown symptom onset or beyond the 4.5-h treatment window. EXPERT COMMENTARY Expanding access to alteplase therapy for acute ischemic stroke is a multi-faceted approach. Specific considerations based on region, population, and health-care resources should be considered for each strategy. Neuroimaging approaches to identify alteplase-eligible patients beyond the 4.5-h treatment window are a recent development in acute stroke care that holds promise for increasing alteplase treatment rates.

Abstract
Background and Purpose- The purpose of these guidelines is to provide an up-to-date comprehensive set of recommendations in a single document for clinicians caring for adult patients with acute arterial ischemic stroke. The intended audiences are prehospital care providers, physicians, allied health professionals, and hospital administrators. These guidelines supersede the 2013 Acute Ischemic Stroke (AIS) Guidelines and are an update of the 2018 AIS Guidelines. Methods- Members of the writing group were appointed by the American Heart Association (AHA) Stroke Council's Scientific Statements Oversight Committee, representing various areas of medical expertise. Members were not allowed to participate in discussions or to vote on topics relevant to their relations with industry. An update of the 2013 AIS Guidelines was originally published in January 2018. This guideline was approved by the AHA Science Advisory and Coordinating Committee and the AHA Executive Committee. In April 2018, a revision to these guidelines, deleting some recommendations, was published online by the AHA. The writing group was asked review the original document and revise if appropriate. In June 2018, the writing group submitted a document with minor changes and with inclusion of important newly published randomized controlled trials with >100 participants and clinical outcomes at least 90 days after AIS. The document was sent to 14 peer reviewers. The writing group evaluated the peer reviewers' comments and revised when appropriate. The current final document was approved by all members of the writing group except when relationships with industry precluded members from voting and by the governing bodies of the AHA. These guidelines use the American College of Cardiology/AHA 2015 Class of Recommendations and Level of Evidence and the new AHA guidelines format. Results- These guidelines detail prehospital care, urgent and emergency evaluation and treatment with intravenous and intra-arterial therapies, and in-hospital management, including secondary prevention measures that are appropriately instituted within the first 2 weeks. The guidelines support the overarching concept of stroke systems of care in both the prehospital and hospital settings. Conclusions- These guidelines provide general recommendations based on the currently available evidence to guide clinicians caring for adult patients with acute arterial ischemic stroke. In many instances, however, only limited data exist demonstrating the urgent need for continued research on treatment of acute ischemic stroke.

Abstract
Introduction There is considerable interest in triaging victims of large vessel occlusion (LVO) strokes to comprehensive stroke centers. Timely access to interventional therapy has been linked to improved stroke outcomes. Accurate triage depends upon the use of a validated screening tool in addition to several emergency medical system (EMS)-specific factors. This study examines the integration of a modified Rapid Arterial oCcclusion Evaluation (mRACE) score into an existing stroke treatment protocol. Methods We performed a retrospective review of EMS and hospital charts of patients transported to a single comprehensive stroke center. Adult patients with an EMS provider impression of “stroke/TIA,” “CVA,” or “neurological problem” were included for analysis. EMS protocols mandated the use of the Cincinnati Prehospital Stroke Score (CPSS). The novel protocol authorized the use of the mRACE score to identify candidates for triage directly to the comprehensive stroke center. We calculated specificity and sensitivity for various stroke screens (CPSS and a mRACE exam) for the detection of LVO stroke. The score’s metrics were evaluated as a surrogate marker for a successful EMS triage protocol. Results We included 312 prehospital charts in the final analysis. The CPSS score exhibited reliable sensitivity at 85%. Specificity of CPSS for an LVO was calculated at 73%. For an mRACE score of five or greater, the sensitivity was 25%. Specificity for mRACE was calculated at 75%. The positive predictive value of the mRACE score for an LVO was estimated at 12.50%. Conclusion In this retrospective study of patients triaged to a single comprehensive stroke center, the addition of an LVO-specific screening tool failed to improve accuracy. Reliable triage of LVO strokes in the prehospital setting is a challenging task. In addition to statistical performance of a particular stroke score, a successful EMS protocol should consider system-based factors such as provider education and training. Study limitations can inform future iterations of LVO triage protocols.

Abstract
Prehospital stroke code activation results in reduced pre- and in-hospital delays and triage and transport of stroke patients to the right centers. In Paraguay, data about acute reper fusion treatment are not available. Recently, a pilot prehospital stroke code program was implemented in the country in November 2016. In an observational, single-center cohort study with a before–after design, from April 2015 to July 2018, we found that 193/832 (23.1%) of stroke patients were stroke code activated, and from these, 54 (6.5%) were brought to hospital under the prehospital stroke code protocol. Fifty-eight patients (58 alteplase and 2 additional endovascular treatment) received reperfusion therapy. Prehospital stroke code patients had a lower mean door-to-CT time (24 vs. 33 min, p = 0.021) and lower mean door-to-needle time (35.3 vs.76.3 min, p < 0.001) compared to in-hospital stroke code patients. Prehospital stroke code is feasible in Paraguay and has a positive impact on in-hospital acute stroke management, reducing delays and increasing the rates of reperfusion treatments.

Abstract
In 2005, the American Stroke Association published recommendations for the establishment of stroke systems of care and in 2013 expanded on them with a statement on interactions within stroke systems of care. The aim of this policy statement is to provide a comprehensive review of the scientific evidence evaluating stroke systems of care to date and to update the American Stroke Association recommendations on the basis of improvements in stroke systems of care. Over the past decade, stroke systems of care have seen vast improvements in endovascular therapy, neurocritical care, and stroke center certification, in addition to the advent of innovations, such as telestroke and mobile stroke units, in the context of significant changes in the organization of healthcare policy in the United States. This statement provides an update to prior publications to help guide policymakers and public healthcare agencies in continually updating their stroke systems of care in light of these changes. This statement and its recommendations span primordial and primary prevention, acute stroke recognition and activation of emergency medical services, triage to appropriate facilities, designation of and treatment at stroke centers, secondary prevention at hospital discharge, and rehabilitation and recovery.

Abstract
Background Traditionally, patients undergoing acute ischemic strokes were candidates for mechanical thrombectomy if they were within the 6-h window from onset of symptoms. This timeframe would exclude many patient populations, such as wake-up strokes. However, the most recent clinical trials, DAWN and DEFUSE3, have expanded the window of endovascular treatment for acute ischemic stroke patients to within 24 h from symptom onset. This expanded window increases the number of potential candidates for endovascular intervention for emergent large vessel occlusions and raises the question of how to efficiently screen and triage this increase of patients. Summary Abbreviated pre-hospital stroke scales can be used to guide EMS personnel in quickly deciding if a patient is undergoing a stroke. Telestroke networks connect remote hospitals to stroke specialists to improve the transportation time of the patient to a comprehensive stroke center for the appropriate level of care. Mobile stroke units, mobile interventional units, and helistroke reverse the traditional hub-and-spoke model by bringing imaging, tPA, and expertise to the patient. Smartphone applications and social media aid in educating patients and the public regarding acute and long-term stroke care. Key Messages The DAWN and DEFUSE3 trials have expanded the treatment window for certain acute ischemic stroke patients with mechanical thrombectomy and subsequently have increased the number of potential candidates for endovascular intervention. This expansion brings patient screening and triaging to greater importance, as reducing the time from symptom onset to decision-to-treat and groin puncture can better stroke patient outcomes. Several strategies have been employed to address this issue by reducing the time of symptom onset to decision-to-treat time.

Abstract
Acute ischemic stroke (AIS) is among the leading causes of death and long-term disability. Intravenous tissue plasminogen activator has been the mainstay of acute therapy. Recently, several prospective randomized trials documented the value of endovascular revascularization in selected patients with large-vessel occlusion within the anterior circulation. This finding has led to a paradigm shift in the management of AIS, including wide adoption of noninvasive neuroimaging to assess vessel patency and tissue viability, with the supplemental and independent use of intravenous tissue plasminogen activator to improve clinical outcomes. In this article, we review the landmark studies on management of AIS and the current position on the diagnosis and management of AIS. The review also highlights the importance of early stabilization and prompt initiation of therapeutic interventions before, during, and after the diagnosis of AIS within and outside of the hospital.

Abstract
OBJECTIVE Prehospital recognition of an acute stroke improves the time from onset to thrombolysis and rates of reperfusion therapy. Studies conducted to evaluate paramedic and dispatcher performance in suspecting stroke are disappointing. This study addresses the specific issue of stroke recognition by dispatchers, taking into account delay in reporting the onset of symptoms (<5 h). METHODS This is an observational analysis conducted over a 12-month period. Dispatchers used a modified Cincinnati Stroke Scale to specifically identify acute strokes in a criteria-based dispatch. Data were extracted from the State's dispatch and the State's stroke centre. All calls to the dispatch were included. Dispatcher's suspicion of acute stroke and the patient's final destination and diagnosis were collected. Simple descriptive statistics were used. Sensitivity and positive predictive value were calculated. RESULTS The dispatch received 27 719 calls resulting in ambulance dispatches; 427 calls [1.5%; 95% confidence interval (CI) 1.4-1.7] were classified as suspicion of acute stroke by dispatchers, and 40 of them (9.4%; 95% CI 6.6-12.1) fulfilled the criteria for thrombolysis (sensitivity 67.8%; 95% CI 54.3-79.4%). Dispatchers missed 19 of 59 strokes (32.2%; 95% CI 20.3-44.1) that received thrombolysis; 16 cases were missed because of unspecific acute symptoms (unconsciousness, dyspnoea), and three more because of unspecific nonacute symptoms (vertigo, dizziness). CONCLUSION The revised Cincinnati Stroke Scale for dispatch adds the notion of delay in the process of triage. It identifies 67.8% and misses 32.2% of the stroke patients treated by thrombolysis. Its performance is similar to previous results using the regular Cincinnati Stroke Scale, but allows for targeting acute strokes.

Abstract
BACKGROUND AND PURPOSE The purpose of these guidelines is to provide an up-to-date comprehensive set of recommendations for clinicians caring for adult patients with acute arterial ischemic stroke in a single document. The intended audiences are prehospital care providers, physicians, allied health professionals, and hospital administrators. These guidelines supersede the 2013 guidelines and subsequent updates. METHODS Members of the writing group were appointed by the American Heart Association Stroke Council's Scientific Statements Oversight Committee, representing various areas of medical expertise. Strict adherence to the American Heart Association conflict of interest policy was maintained. Members were not allowed to participate in discussions or to vote on topics relevant to their relations with industry. The members of the writing group unanimously approved all recommendations except when relations with industry precluded members voting. Prerelease review of the draft guideline was performed by 4 expert peer reviewers and by the members of the Stroke Council's Scientific Statements Oversight Committee and Stroke Council Leadership Committee. These guidelines use the American College of Cardiology/American Heart Association 2015 Class of Recommendations and Levels of Evidence and the new American Heart Association guidelines format. RESULTS These guidelines detail prehospital care, urgent and emergency evaluation and treatment with intravenous and intra-arterial therapies, and in-hospital management, including secondary prevention measures that are appropriately instituted within the first 2 weeks. The guidelines support the overarching concept of stroke systems of care in both the prehospital and hospital settings. CONCLUSIONS These guidelines are based on the best evidence currently available. In many instances, however, only limited data exist demonstrating the urgent need for continued research on treatment of acute ischemic stroke.

Abstract
BACKGROUND Early hospital notification of a possible stroke arriving via emergency medical services (EMS) can prepare stroke center personnel for timely treatment, especially timely administration of tissue plasminogen activator. Stroke center notification from the emergency dispatch center-before responders reach the scene-may promote even earlier and faster system activation, meaning that stroke center teams may be ready to receive patients as soon as the ambulance arrives. This study evaluates the use of a Medical Priority Dispatch System (MPDS; Priority Dispatch Corp., Salt Lake City, UT) Stroke Diagnostic Tool (SDxT) to identify possible strokes early by comparing the tools' results to on-scene and hospital findings. METHODS The retrospective descriptive study utilized stroke data from 3 sources: emergency medical dispatch, EMS, and emergency department/hospital. RESULTS A total of 830 cases were collected between June 2012 and December 2013, of which 603 (72.7%) had matching dispatch records. Of the 603 cases, 304 (50.4%) were handled using MPDS Stroke Protocol 28. The SDxT had an 86.4% ability (OR [95% CI]: 2.3 [1.5, 3.5]) to effectively identify strokes among all the hospital-confirmed stroke cases (sensitivity), and a 26.6% ability to effectively identify nonstrokes among all the hospital-confirmed nonstroke cases (specificity). CONCLUSIONS The SDxT demonstrated a very high sensitivity, compared to similar tools used in the field and at dispatch. The specificity was somewhat low, but this was expected-and is intended in the creation of protocols to be used over the phone in emergency situations. The tool is a valuable method for identifying strokes early and may allow early hospital notification.

Abstract
Over the last 15 years, new approaches regarding neuroprotective and thrombolytic strategies in stroke management have been evaluated in the prehospital setting. These efforts have provided exciting new potentials of hyperacute stroke care. Trials have shown that the use of specialized stroke ambulances increases the proportion of patients receiving intravenous thrombolysis and shortens alarm-to-treatment time by approximately half an hour compared to standard care. Intravenous thrombolysis within the ultra-early time window of the 'golden hour' has become a realistic scenario. However, direct effects of prehospital stroke care on functional outcome have yet to be shown and other approaches such as neuroprotective treatments could not demonstrate clinical benefit so far. There is a clear need for systematic research in the prehospital field to test the clinical effectiveness and cost-effectiveness of new therapeutic strategies. It will be necessary to test various components of prehospital stroke care alone and in combination.

Abstract
BACKGROUND The emergency medical service is designed to recognize and transfer critically ill patients. Evidence-based practice has rarely been emphasized in the emergency medical service field, especially in the dispatch center. AIMS To identify the effect of the Cincinnati Prehospital Stroke Scale (CPSS) on telephone triage of stroke patients by telephone triage nurses at the emergency medical dispatch center and to compare CPSS with the National Guidelines for Telephone Triage Tool (NGTT). METHODS A quasi-empirical study was conducted from June 2013 to June 2014. The setting of the study was the Mashhad dispatch center of the EMS. Two hundred and forty-six patients were randomly allocated to the CPSS intervention group (n = 121) and the NGTT control group (n = 125). True triage, triage error and odds ratio were statistically reported. RESULTS The mean age of the patients was 70.9 ± 12.7 years. Of all the cases, 77.7 and 65.6% of patients in the intervention and the control groups, respectively, were accurately triaged. Under-triage cases were 10.7 and 13.6% of the patients in the intervention and the control groups. Odds ratio was 1.14 (95% confidence interval 0.62-2.07) for the CPSS compared with the NGTT. CONCLUSION CPSS is more efficient for use by telephone triage nurses in identifying stroke. The use of CPSS assists nurses by reducing the triage error and supports the evidence-based care. It needs to be developed to cover signs and symptoms of posterior-circulation stroke patients.

Abstract
There has been a tremendous evolution in the stroke systems of care in the USA. Public awareness, prehospital care, and in-hospital protocols have never been so effectively connected. However, given the critical role of time to effective reperfusion in the setting of acute ischemic stroke, it is vital and timely to implement strategies to further streamline emergency stroke care. This article reviews the most current standards and guidelines related to the flow of stroke care in the prehospital and emergency settings.

Abstract
BACKGROUND AND PURPOSE Prehospital activation of in-hospital stroke response hastens treatment but depends on accurate emergency medical services (EMS) stroke recognition. We sought to measure EMS stroke recognition accuracy and identify clinical factors associated with correct stroke identification. METHODS Using EMS and hospital records, we assembled a cohort of EMS-transported suspect, confirmed, or missed ischemic stroke or transient ischemic attack cases. The sensitivity and positive predictive value (PPV) for EMS stroke recognition were calculated using the hospital discharge diagnosis as the gold standard. We used multivariable logistic regression analysis to determine the association between Cincinnati Prehospital Stroke Scale use and EMS stroke recognition. RESULTS During a 12-month period, 441 EMS-transported patients were enrolled; of which, 371 (84.1%) were EMS-suspected strokes and 70 (15.9%) were EMS-missed strokes. Overall, 264 cases (59.9%) were confirmed as either ischemic stroke (n=186) or transient ischemic attack (n=78). The sensitivity of EMS stroke recognition was 73.5% (95% confidence interval, 67.7-78.7), and PPV was 52.3% (95% confidence interval, 47.1-57.5). Sensitivity (84.7% versus 30.9%; P<0.0001) and PPV (56.2% versus 30.4%; P=0.0004) were higher among cases with Cincinnati Prehospital Stroke Scale documentation. In multivariate analysis, Cincinnati Prehospital Stroke Scale documentation was independently associated with EMS sensitivity (odds ratio, 12.0; 95% confidence interval, 5.7-25.5) and PPV (odds ratio, 2.5; 95% confidence interval, 1.3-4.7). CONCLUSIONS EMS providers recognized 3 quarters of the patients with ischemic stroke and transient ischemic attack; however, half of EMS-suspected strokes were false positives. Documentation of a Cincinnati Prehospital Stroke Scale was associated with higher EMS stroke recognition sensitivity and PPV.

Abstract
TeleStroke has become an increasing means to overcome shortage of stroke expertise in underserved areas. This rapidly growing field has triggered a large amount of publications in recent years. We aimed to analyze recent advances in the field of telemedicine for acute stroke, with main focus on prehospital management, Stroke Unit treatment and network implementations in developing countries. Out of 260 articles, 25 were selected for this systematic review: 9 regarding prehospital management, 14 regarding Stroke Unit treatment and 2 describing a network in developing countries. Prehospital management showed that stroke recognition can start at the dispatch emergency call, important clinical information can be electronically transmitted to hospitals before admission and even acute treatment such as thrombolysis can be initiated in the prehospital field if ambulances are equipped with CT scan and point-of-care laboratory. Articles on remote clinical examination, telemedical imaging interpretation, trial recruitment and cost-effectiveness described various aspects of Stroke Unit treatment within TeleStroke networks, underlining reliability, safety and cost savings of these systems of care. Only one network was described to have been implemented in a developing/emerging nation. TeleStroke is a growing field expanding its focus to a broader spectrum of stroke care. It still seems to be underused, particularly in developing countries.
