RESUMO
BACKGROUND: Tenecteplase (TNK) is considered a promising option for the treatment of acute ischemic stroke (AIS) with the potential to decrease door-to-needle times (DTN). This study investigates DTN metrics and trends after transition to tenecteplase. METHODS: The Lone Star Stroke (LSS) Research Consortium TNK registry incorporated data from three Texas hospitals that transitioned to TNK. Subject data mapped to Get-With-the-Guidelines stroke variables from October 1, 2019 to March 31, 2023 were limited to patients who received either alteplase (ALT) or TNK within the 90 min DTN times. The dataset was stratified into ALT and TNK cohorts with univariate tables for each measured variable and further analyzed using descriptive statistics. Logistic regression models were constructed for both ALT and TNK to investigate trends in DTN times. RESULTS: In the overall cohort, the TNK cohort (n = 151) and ALT cohort (n = 161) exhibited comparable population demographics, differing only in a higher prevalence of White individuals in the TNK cohort. Both cohorts demonstrated similar clinical parameters, including mean NIHSS, blood glucose levels, and systolic blood pressure at admission. In the univariate analysis, no difference was observed in median DTN time within the 90 min time window compared to the ALT cohort [40 min (30-53) vs 45 min (35-55); P = .057]. In multivariable models, DTN times by thrombolytic did not significantly differ when adjusting for NIHSS, age (P = .133), or race and ethnicity (P = .092). Regression models for the overall cohort indicate no significant DTN temporal trends for TNK (P = .84) after transition; nonetheless, when stratified by hospital, a single subgroup demonstrated a significant DTN upward trend (P = 0.002). CONCLUSION: In the overall cohort, TNK and ALT exhibited comparable temporal trends and at least stable DTN times. This indicates that the shift to TNK did not have an adverse impact on the DTN stroke metrics. This seamless transition is likely attributed to the similarity of inclusion and exclusion criteria, as well as the administration processes for both medications. When stratified by hospital, the three subgroups demonstrated variable DTN time trends which highlight the potential for either fatigue or unpreparedness when switching to TNK. Because our study included a multi-ethnic cohort from multiple large Texas cities, the stable DTN times after transition to TNK is likely applicable to other healthcare systems.

OBJECTIVES: Prior to our study, little was known about factors related to time-to-treatment for stroke pre- and post-COVID-19. DESIGN: This was a retrospective cohort study to evaluate factors associated with delayed door-to-needle time among patients with acute ischemic stroke over two time-periods. RESULTS: Final sample consisted of 932 charts with mean age of 68.1(±15.6). Significant factors associated with shorter door-to-needle time included ≤ four hours since symptom onset and stroke occurring during post-Covid-19 time-period. Those on anti-coagulants had 72 % higher odds of longer door-to-needle time. As patients got older and stroke symptoms were more severe, less time was spent in door-to-imaging. CONCLUSION: Results highlight the importance of early recognition of stroke symptoms and rapid transport to the hospital. Faster response times in post-Covid-19 time-period may be attributable to systematic processes put in place to address pandemic-related challenges. Outcomes may depend on research to identify gaps in stroke treatment.

BACKGROUND: Door-to-needle time (DNT) is a critical consideration in emergency management of acute ischemic stroke (AIS). Deficiencies in the widely applied standard hospital workflow process, based on international guidelines, impede rapid treatment of AIS patients. We developed an in-hospital stroke system to reduce DNT and optimize hospitals' emergency procedures. OBJECTIVES: To investigate the effect of the in-hospital stroke system on the hospital workflow for AIS patients. METHODS: We performed a retrospective study on AIS patients between June 2017 and December 2021. AIS cases were assigned to a pre-intervention group (before the in-hospital stroke system was established) and a post-intervention group (after the system's establishment). We compared the two groups' demographic features, clinical characteristics, treatments and outcomes, and time metrics data. RESULTS: We analyzed 1031 cases, comprising 474 and 557 cases in the pre-intervention and post-intervention groups, respectively. Baseline data were similar for both groups. Significantly more patients in the post-intervention group (41.11%) were treated with intravenous thrombolysis (IVT) or endovascular therapy (ET) compared with those in the pre-intervention group (8.65%) (p < 0.001). DNT was markedly improved (decreasing from 118 (80.5-137) min to 26 (21-38) min among patients in the post-intervention group treated with IVT or bridging ET. Consequently, a much higher proportion of these patients (92.64%) received IVT within 60 min compared with those in the pre-intervention group (17.39%) (p < 0.001). Consequently, their hospital stays were shorter (8 [6-11] days vs. 10 [8-12] days for the pre-intervention group; p < 0.001), and they showed improved National Institutes of Health Stroke Scale (NIHSS) scores at discharge (-2 [-5-0] vs. -1 [-2-0], p < 0.001). CONCLUSION: DNT was significantly reduced following implementation of the in-hospital stroke system, which contributed to improved patient outcomes measured by the length of hospital stay and NIHSS scores.

OBJECTIVES: Time from onset to reperfusion affects mortality and favorable outcomes in patients with acute ischemic stroke (AIS). To evaluate effects of a real-time feedback mobile application on critical time intervals and functional outcomes in stroke emergency management. METHODS: We recruited patients with clinically suspected acute stroke from December 1st, 2020 until July 30st, 2022. All Patients had a non-contrast computed tomography (CT) and were included only if they had AIS. We divided the patients into two groups based on the date of availability on mobile application: pre-APP group and post-APP group. Onset to Door time (ODT), Door to Imaging Time (DIT), Door to Needle Time (DNT), Door to Puncture Time (DPT), Door to Recanalization Time (DRT), National Institutes of Health Stroke Scale (NIHSS) and modified Rankin Scale (mRS) were compared between two groups. RESULTS: We retrospectively enrolled 312 AIS patients who were assigned into the pre-APP group (n = 159) and post-APP group (n = 153). The median ODT time and median admission NIHSS score were not significantly different between the two groups at baseline assessment. The median (IQR) DIT [44 (30-60) min vs 28 (20-36) min, P < 0.01] and DNT [44 (36.25-52) min vs 39 (29-45) min, P = 0.02] both decreased significantly in two groups. However, median DPT and DRT time showed no significant differences. The proportion of mRS score of 0 to 2 at day 90 was significantly higher in the post-App group than in the pre-App group, at 82.4% and 71.7%, respectively (dominance ratio OR=1.84, 95% CI: 1.07 to 3.16, P = 0.03). CONCLUSION: The present findings indicate that the real-time feedback of stroke emergency management used by a mobile application have potential for shortening the DIT and DNT time and improve the prognosis of stroke patients.

Background: Recombinant tissue plasminogen activator (rtPA) has revolutionized the management of acute ischemic stroke. Shorter door-to-imaging and door-to-needle (DTN) times are crucial for improving the outcomes in thrombolysed patients. Our observational study evaluated the door-to-imaging time (DIT) and DTN times for all thrombolysed patients. Materials and methods: The study was a cross-sectional observational study over a period of 18 months at a tertiary care teaching hospital and included 252 acute ischemic stroke patients of which 52 underwent thrombolysis with rtPA. The time intervals between arrival to neuroimaging and initiation of thrombolysis were noted. Result: Of the total patients thrombolysed, only 10 patients underwent neuroimaging [non-contrast computed tomography (NCCT) head with MRI brain screen] within 30 minutes of their arrival in the hospital, 38 patients within 30-60 minutes and 2 each within the 61-90 and 91-120 minute time frames. The DTN time was 30-60 minutes for 3 patients, while 31 patients were thrombolysed within 61-90 minutes, 7 patients within 91-120 minutes, while 5 each took 121-150 and 151-180 minutes for the same. One patient had a DTN between 181 and 210 minutes. Conclusion: Most patients included in the study underwent neuroimaging within 60 minutes and subsequent thrombolysis within 60-90 minutes of their arrival in the hospital. But the time frames did not meet the recommended ideal intervals, and further streamlining of stroke management is needed even at tertiary care centers in India.

RESUMO
BACKGROUND AND PURPOSE: Rapid access to acute stroke treatment improves clinical outcomes in patients with ischemic stroke. We aimed to shorten the time to admission and to acute stroke treatment for patients with acute stroke in the Hamburg metropolitan area by collaborative multilevel measures involving all hospitals with stroke units, the Emergency Medical Services (EMS), and health-care authorities. METHODS: In 2007, an area-wide stroke care quality project was initiated. The project included mandatory admission of all stroke patients in Hamburg exclusively to hospitals with stroke units, harmonized acute treatment algorithms among all hospitals, repeated training of the EMS staff, a multimedia educational campaign, and a mandatory stroke care quality monitoring system based on structured data assessment and quality indicators for procedural measures. We analyzed data of all patients with acute stroke who received inhospital treatment in the city of Hamburg during the evaluation period from the quality assurance database data and evaluated trends of key quality indicators over time. RESULTS: From 2007 to 2016, a total of 83,395 patients with acute stroke were registered. During this period, the proportion of patients admitted within ≤3 h from symptom onset increased over time from 27.8% in 2007 to 35.2% in 2016 (p < 0.001). The proportion of patients who received rapid thrombolysis (within ≤30 min after admission) increased from 7.7 to 54.1% (p < 0.001). CONCLUSIONS: Collaborative stroke care quality projects are suitable and effective to improve acute stroke care.

OBJECTIVES: This study aims to evaluate shortening door-to-needle time of intravenous recombinant tissue plasminogen activator of acute ischemic stroke patients by multidisciplinary collaboration and workflow optimization based on our hospital resources. MATERIALS AND METHODS: We included patients undergoing thrombolysis with intravenous recombinant tissue plasminogen activator from January 1, 2018, to September 30, 2020. Patients were divided into pre- (January 1, 2018, to December 31, 2019) and post-intervention groups (January 1, 2020, to September 31, 2020). We conducted multi-department collaboration and process optimization by implementing 16 different measures in prehospital, in-hospital, and post-acute feedback stages for acute ischemic stroke patients treated with intravenous thrombolysis. A comparison of outcomes between both groups was analyzed. RESULTS: Two hundred and sixty-three patients received intravenous recombinant tissue plasminogen activator in our hospital during the study period, with 128 and 135 patients receiving treatment in the pre-intervention and post-intervention groups, respectively. The median (interquartile range) door-to-needle time decreased significantly from 57.0 (45.3-77.8) min to 37.0 (29.0-49.0) min. Door-to-needle time was shortened to 32 min in the post-intervention period in the 3rd quarter of 2020. The door-to-needle times at the metrics of ≤ 30 min, ≤ 45 min, ≤ 60 min improved considerably, and the DNT> 60 min metric exhibited a significant reduction. CONCLUSIONS: A multidisciplinary collaboration and continuous process optimization can result in overall shortened door-to-needle despite the challenges incurred by the COVID-19 pandemic.

Ischemic stroke is defined as neurological deficit caused by brain infarction. The intravenous tissue plasminogen activator, alteplase, is an effective treatment. However, efficacy of this method is time dependent. An important step in improving outcome and increasing the number of patients receiving alteplase is the shortening of waiting times at the hospital, the so-called door-to-needle time (DNT). The comprehensive Helsinki model was proposed in 2012, which enabled the shortening of the DNT to less than 20 min. Background and Objectives: The aim of this study was to analyze the transferability of the suggested model to the West Tallinn Central Hospital (WTCH). Materials and Methods: Since the first thrombolysis in 2005, all patients are registered in the WTCH thrombolysis registry. Several steps following the Helsinki model have been implemented over the years. Results: The results demonstrate that the number and also the percent of thrombolysed stroke patients increased during the years, from a few thrombolysis annually, to 260 in 2021. The mean DNT dropped significantly to 33 min after the implementation of several steps, from the emergency medical services (EMS) prenotification with a phone call to the neurologists, to the setting-up of a thrombolysis team based in the stroke unit. Also, the immediate start of treatment using a computed tomography table was introduced. Conclusions: In conclusion, several implemented steps enabled the shortening of the DNT from 30 to 25.2 min. Short DNTs were achieved and maintained only with EMS prenotification.

RESUMO
OBJECTIVE: To describe the impact of COVID-19 on acute cerebrovascular disease care across 9 comprehensive stroke centers throughout Los Angeles County (LAC). METHODS: Volume of emergency stroke code activations, patient characteristics, stroke severity, reperfusion rates, treatment times, and outcomes from February 1 to April 30, 2020, were compared against the same time period in 2019. Demographic data were provided by each participating institution. RESULTS: There was a 17.3% decrease in stroke code activations across LAC in 2020 compared to 2019 (1,786 vs. 2,159, respectively, χ2 goodness of fit test p < 0.0001) across 9 participating comprehensive stroke centers. Patients who did not receive any reperfusion therapy decreased by 16.6% in 2020 (1,527) compared to 2019 (1,832). Patients who received only intravenous thrombolytic (IVT) therapy decreased by 31.8% (107 vs. 157). Patients who received only mechanical thrombectomy (MT) increased by 3% (102 vs. 99). Patients who received both IVT and MT decreased by 31.8% (45 vs. 66). Recanalization treatment times in 2020 were comparable to 2019. CSCs serving a higher proportion of Latinx populations in the eastern parts of LAC experienced a higher incidence of MT in 2020 compared to 2019. Mild increase in stroke severity was seen in 2020 compared to 2019 (8.95 vs. 8.23, p = 0.046). A higher percentage of patients were discharged home in 2020 compared to 2019 (59.5 vs. 56.1%, p = 0.034), a lower percentage of patients were discharged to skilled nursing facility (16.1 vs. 20.7%, p = 0.0004), and a higher percentage of patients expired (8.6 vs. 6.3%, p = 0.008). CONCLUSION: LAC saw a decrease in overall stroke code activations in 2020 compared to 2019. Reperfusion treatment times remained comparable to prepandemic metrics. There has been an increase in severe stroke incidence and higher volume of thrombectomy treatments in Latinx communities within LAC during the pandemic of 2020. More patients were discharged home, less patients discharged to skilled nursing facilities, and more patients expired in 2020, compared to the same time frame in 2019.

BACKGROUND: Reports have proven that shorter door-to-needle time (DTN time) indicates better outcomes in AIS patients received intravenous thrombolysis. Efforts have been made by hospitals and centers to minimize DTN time in many ways including introducing a stroke nurse. However, there are few studies to discuss the specific effect of stroke nurse on patients' prognosis. This study aimed to compare consecutive AIS patients before and after the intervention to analyze the effect of stroke nurse on clinical outcome of AIS patients. METHODS: In this retrospective study, we observed 1003 patients from November 2016 to December 2020 dividing in two groups, collected and analyzed AIS patients' medical history, clinical assessment information, important timelines, 90 mRS score, etc. Comparative analysis and mediation analysis were also used in this study. RESULTS: A total of 418 patients was included in this study, and 199 patients were enrolled in the stroke nurse group and 219 was in the preintervention group. Baseline characteristics of patients showed no significant difference except there seems more patients with previous ischemic stroke history in the group of stroke nurse. (p = 0.008). The median DTN time significantly decreased in the stroke nurse group (25 min versus 36 min, p < 0.001) and multivariate logistic regression analysis showed the 90-day mRS clinical outcome significantly improved in the stroke nurse group (p = 0.001). Mediation analysis indicated the reduction of DTN time plays a partial role on the 90 days mRS score and the stroke nurse has some direct effect on the improvement of clinical outcome (p = 0.006). CONCLUSIONS: The introduction of stroke nurse is beneficial to clinical outcome of AIS patients and can be use of reference in other hospitals or centers.

OBJECTIVES: Monitoring critical time intervals in acute ischemic stroke treatment delivers metrics for quality of performance - the door-to-needle time being well-established. To resolve the conflict of self-reporting bias a "StrokeWatch" was designed - an instrument for objective standardized real-time measurement of procedural times. MATERIALS AND METHODS: An observational, monocentric analysis of patients receiving intravenous thrombolysis for acute ischemic stroke between January 2018 and September 2019 was performed based on an ongoing investigator-initiated, prospective, and blinded endpoint registry. Patient data and treatment intervals before and after introduction of "StrokeWatch" were compared. RESULTS: "StrokeWatch" was designed as a mobile board equipped with three digital stopwatches tracking door-to-needle, door-to-groin, and door-to-recanalization intervals as well as a form for standardized documentation. 118 patients before introduction of "StrokeWatch" (subgroup A) and 53 patients after introduction of "StrokeWatch" (subgroup B) were compared. There were no significant differences in baseline characteristics, procedural times, or clinical outcome. A non-significant increase in patients with door-to-needle intervals of 60 min or faster (93.2 vs 98.1%, p = 0.243) and good functional outcome (mRS d90 ≤ 2, 47.5 vs 58.5%, pâ¯=â¯0.218) as well as a significant increase in reports of delayed arrival of intra-hospital patient transport service (0.8 vs 13.2%, p = 0.001) were observed in subgroup B. CONCLUSIONS: The implementation of StrokeWatch for objective standardized real-time measurement of door-to-needle times is feasible in a real-life setting without negative impact on procedural times or outcome. It helped to reassure a high-quality treatment standard and reveal factors associated with procedural delays.

BACKGROUND: Time to revascularization is critical in improving outcomes in stroke thrombolysis. We studied the effectiveness of a mobile app based strategy to improve door-to-needle time (DNT) in treatment of acute ischemic stroke. METHODS: Consecutive patients presenting with acute ischemic stroke to the emergency department at a tertiary care hospital in Southern India between April 2017 - September 2018 were included. The app enabled rapid entry of patient parameters, the NIH stroke scale (NIHSS), thrombolysis checklist and dose calculation along with team synchronization, notifying all on-call members and team leaders of the patient movement, and sharing of radiological images. DNT captured from the app was compared to previous values from our center using one-way Analysis of Variance (ANOVA) after adjusting for differences in baseline variables. RESULTS: A total of 76 patients were thrombolysed during the study period, while using the mobile app. The mean DNT was 41 min, with 89% being thrombolysed within 60 min and 57% being thrombolysed within 45 min. Compared to 100 consecutive patients thrombolysed in the months prior to April 2017 where the mean DNT was 57 min, with 67% thrombolysed within 60 min and 47% being thrombolysed within 45 min, there was a mean DNT decrease of 16 min with 1.3x increase in DNT < 60 min. This difference was statistically significant after adjusting for age, sex and NIHSS Score (p=0.005, One-Way ANOVA). CONCLUSION: We have been able to demonstrate a significant improvement in DNT using mobile app as a tool to improve team performance.

BACKGROUND: The benefit of intravenous thrombolysis (IVT) for acute ischemic stroke is time dependent. Despite great effort, the median door-to-needle time (DNT) was 60 min at the United States stroke centers. We investigated the effect of a simple quality improvement initiative on DNT for IVT. METHODS: This is a single-center study of patients treated with IVT between 2013 and 2017. A simple quality improvement initiative was implemented in January 2015 to allow the Stroke team to manage hypertension in the emergency room, to make decision for IVT before getting blood test results unless patients were taking oral anticoagulants, and to give IVT in the CT suite. Baseline characteristics, DNT and outcomes at hospital discharge were compared between pre- and post-intervention groups. RESULTS: Ninety and 136 patients were treated with IVT in pre- and post-intervention groups, respectively. The rate of IVT was significantly higher in the post-intervention group (20% vs. 14.4%, p = 0.007). The median DNT with interquartile range (IQR) was reduced significantly by 23 min (63[53-81] vs. 40[29-53], p < 0.001) with more patients in the post-intervention group receiving IVT within 60 min (81.6% vs. 46.7%) and 45 min (64.0% vs.17.8%). There was no significant difference in symptomatic intracerebral hemorrhage rate (1.5% vs. 1.1%), modified Rankin Scale 0-1 (29.4% vs. 23.3%), and hospital mortality (7.4% vs. 6.7%) between the 2 groups. CONCLUSIONS: Three easily-implementable quality improvement initiative increases IVT rate and reduces DNT significantly without increasing the rate of IVT-related complications in our comprehensive stroke center.

We included acute ischemic stroke (AIS) patients who received recombinant tissue plasminogen activator (rt-PA) at three stroke centers via either interhospital transfer or direct presentation and compared the clinical outcomes and time metrics to analyze the impact of interhospital transfer on intravenous thrombolysis (IVT). We retrospectively enrolled patients with AIS admitted to three stroke centers from October 1, 2016, to June 1, 2018. Patients treated with rt-PA were classified into the transfer and direct groups. We collected the patients' general information and time points. Statistical analyses were conducted to examine differences in the clinical outcomes and time metrics between the two groups. A total of 326 patients were enrolled, including 84 patients in the transfer group and 242 in the direct group. The transfer group had a longer onset-to-door time (OTD) (124.5 ± 50.6 min versus 83.2 ± 47.2 min, P < 0.01) but a shorter door-to-needle time (DNT) (53.0 ± 26.3 min versus 81.5 ± 31.1 min, P < 0.01), and the stroke onset-to-needle time was 177.4 ± 51.0 min versus 164.7 ± 53.3 min (P = 0.057). Compared with the direct group, the transfer group achieved similar modified Rankin scale (mRS) 0-2 outcomes (59.5% versus 58.7%, P = 0.768). Interhospital transfer was not an independent risk factor associated with a poor outcome at 90 days. In three Chinese municipal stroke centers, patients with an AIS referral have a longer OTD but a shorter DNT. DNTs of municipal hospitals were far longer than the current international standard, and their improvement is an important task.

BACKGROUND: Intravenous recombinant tissue plasminogen activator (rt-PA) has become a common treatment for acute ischemic stroke and has highly time-dependent benefits. We aimed to clarify temporal trends regarding the frequency and characteristics of patients receiving rt-PA and explore factors associated with door-to-needle time (DNT) in Japanese emergency hospitals. METHODS: Consecutive patients who received intravenous rt-PA for acute ischemic stroke from October 2005 to December 2015 were retrospectively registered from 4 hospitals. Temporal trends in the frequency and characteristics of patients receiving rt-PA and factors associated with DNT were investigated. RESULTS: A total of 750 patients, including 688 (420 men, median 75 years old) with out-of-hospital stroke, were registered. The frequency of patients receiving intravenous rt-PA for acute ischemic stroke continuously increased from 1.8% in 2005 to 9.5% in 2015. The proportion of patients who were elderly or had prestroke disability increased over time, while pretreatment stroke severity declined. The DNT gradually decreased (median 105 minutes in 2005, 61 minutes in 2015). According to multivariate regression analysis with correction for multiple comparisons, activation of a code stroke system (standardized partial regression coefficient (ß) -.50, P < .001, q < .001), onset-to-door time (ß -.15, P < .001, q < .001), pretreatment with antithrombotic agents (ß .12, P < .001, qâ¯=â¯.001), and year of treatment (ß .11, Pâ¯=â¯.007, qâ¯=â¯.011) were associated with DNT. CONCLUSIONS: Intravenous rt-PA was widely adopted in Japanese emergency hospitals. Characteristics of patients receiving intravenous rt-PA have changed over the past decade. Several factors, including the year of treatment, were associated with DNT, which has shortened over time.

AIMS AND OBJECTIVES: To assess the trends of intravenous (IV) thrombolysis with recombinant tissue plasminogen activator (rt-PA) among patients with acute ischaemic stroke (AIS) admitted to our hospital between 2012-2014 and investigate the effects of a 24-hr stroke thrombolysis emergency treatment on the intrahospital clinical data and outcomes of these patients treated with IV rt-PA thrombolysis. BACKGROUND: Although prenotification of stroke by emergency medical services has been endorsed by the national recommendations and implemented in some developed countries, the development in China is limited. DESIGN: A retrospective, single-centre, observational study. METHODS: Patients with AIS admitted to our hospital between January 2012-December 2014 were included; those who received IV rt-PA thrombolysis within 4.5 hr of onset were investigated. Demographic characteristics, including age and sex, and clinical data and outcomes, including onset-to-treatment time (OTT), door-to-needle time (DNT), premorbid modified Rankin Scale score and proportion of patients treated per year, were all recorded. RESULTS: The proportion of patients with AIS who received thrombolytic therapy within 4.5 hr increased from 2012-2014. The baseline characteristics of all patients were similar. Since the implementation of 24-hr stroke thrombolysis emergency treatment in 2013, the median DNT significantly decreased in 2014 after implementation (42 min) compared with that in 2012 before implementation (81 min) (p < .05). Moreover, the admission-to-imaging time (37 vs. 33 vs. 36 min) and OTT (176 vs. 147 vs. 124 min) significantly decreased during the 3 years (p < .05). CONCLUSIONS: The 24-hr stroke thrombolysis emergency treatment reduced in-hospital delay before thrombolytic therapy but had no effect on the functional outcomes of the patients with AIS. RELEVANCE TO CLINICAL PRACTICE: This study provides opportunities to improve the experiences in using 24-h stroke thrombolysis emergency treatment in patients with AIS in clinical practice.

BACKGROUND: The implementation of telestroke programs has allowed patients living in rural areas suffering from acute ischemic stroke to receive expert acute stroke consultation and intravenous Alteplase (tPA). The purpose of this study is to compare door to needle (DTN) time when tPA is administered at telestroke sites (spokes) through telestroke consultations compared to tPA administration at the comprehensive stroke center (hub). METHODS: Data on all patients who received intravenous tPA at the hub and spoke hospitals through a large telestroke program between May 2008 and December 2016 were collected. Baseline characteristics were compared between the two groups, and the percentage of patients meeting DTN guidelines was compared between the hub and spoke hospitals during the study period. Comparison of DTN before and after the implementation of a quality improvement project was performed. RESULTS: A total of 1,665 patients received tPA at either the spoke (n = 1,323) or the hub (n = 342) during the study period. Baseline characteristics were comparable in both treatment groups. Before the intervention, DTN time <60 min was achieved in 88% of the hub patients versus 38% of the spoke patients. This difference between the two groups decreased by 35 percentage points, controlling for year (p = 0.0018) after the interventions. CONCLUSION: Overall, DTN is longer at the spoke hospitals compared to the hub hospital. This can be improved by various interventions that target quality, training, education, and improving the comfort level of the staff at partner hospitals when treating acute stroke patients.

BACKGROUND: In acute ischemic stroke (AIS), treatment with intravenous tissue-type plasminogen activator (IV-tPA) is time-sensitive. All stroke centers make continual efforts to reduce door-to-needle time (DNT) with varying success. We present the impact of modifications to our stroke activation protocol on DNT. METHODS: We included 404 consecutive patients with AIS receiving IV-tPA between January 2014 and December 2016. First changes in stroke activation protocol were made in March 2015 in the form of prenotification by paramedics, direct transfer from ambulance to computed tomography (CT) scanner, and rapid en route neurological assessment by an emergency physician and neurologist. In March 2016, a second amendment was made where a stroke nurse accompanied the patient to expedite various steps in the treatment pathway, including endovascular treatment in eligible cases. RESULTS: Both protocol amendments resulted in improvement in DNT and door-to-CT time from 84 ± 47 minutes before intervention to 69 ± 33 minutes after protocol amendment 1 to 59 ± 37 minutes after protocol amendment 2. In particular, the second amendment (144 patients) showed significant shortening of DNT compared with the 137 patients before (59 ± 37 minutes versus 69 ± 33 minutes, P = .020), with a higher percentage achieving the target of 60 minutes (68.1% versus 48.2%, P < .001). This finding was attributed to a reduction in both door-to-CT time and CT-to-needle time. This improvement remained consistent over subsequent months. CONCLUSIONS: The application of a simple systems-based, multidisciplinary stroke activation protocol may help in significant reduction in DNT. Encouraging increased patient ownership by stroke nurses appeared to be a promising approach for timely administration of definitive acute therapies.
