Background: “Drip-and-ship” denotes patients in whom intravenous (IV) recombinant tissue plasminogen activator (rt-PA) is initiated at the emergency department (ED) of a community hospital, followed by transfer within 24 hours to a comprehensive stroke center. Although drip-and-ship paradigm has the potential to increase the number of patients who receive IV rt-PA, comparative outcomes have not been assessed at a population based level. Methods: State-wide estimates of thrombolysis, associated in-hospital outcomes and mortality were obtained from 2008-2009 Minnesota Hospital Association (MHA) data. Patient numbers and frequency distributions were calculated for state-wide sample of patients hospitalized with a primary diagnosis of ischemic stroke. Patients outcomes were analyzed after stratification into patients treated with IV rt-PA through primary ED arrival or drip-and-ship paradigm. Results: Of the 21,024 admissions, 602 (2.86%) received IV rt-PA either through primary ED arrival (n=473) or drip-and-ship paradigm (n=129). The rates of secondary intracerebral or subarachnoid hemorrhage were higher in patients treated with IV rt-PA through primary ED arrival compared with those treated with drip-and-ship paradigm (8.5% versus 3.1, p=0.038). The in-hospital mortality rate was similar among ischemic stroke patients receiving IV rt-PA through primary ED arrival or drip-and-ship paradigm (5.9% versus 7.0%). The mean hospital charges were $65,669 for primary ED arrival and $47,850 for drip-and-ship treated patients (p<0.001). Conclusions: The results of drip-and-ship paradigm compare favorably with IV rt-PA treatment through primary ED arrival in this state-wide study.

Background: An echocardiogram or transcranial Doppler (TCD) bubble study to test for a right-to-left shunt (RLS) is a standard component of an ischemic stroke workup. Because the pathway for an intracradiac RLS, such as a patent foramen ovale (PFO), is more direct, it has been proposed that the late appearance of a RLS suggests an extracardiac pathway. We sought to characterize a cohort of ischemic stroke patients with late RLS (LRLS) on TCD. Methods: We searched the medical record of a Comprehensive Stroke Center for patients with ischemic stroke who had a TCD and echocardiogram bubble study during 2011-2013. LRLS was defined as TCD bubbles appearing more than 18 cardiac cycles after contrast injection. TOAST stroke etiology classification was performed by a vascular neurologist blinded to TCD results. Results: 124 patients met inclusion criteria, of which 67/124 (54%) had RLS on TCD; and 32/67 (48%) had LRLS. In the 35/67 patients with normal RLS on TCD, 23% did not have RLS on echocardiography, consistent with prior reports of TCD’s superiority for detecting RLS. In the 32/67 patients with LRLS on TCD, 56% were negative for RLS by echocardiography. In the cohort of 124 patients, the percentage of TOAST classification 4 (stroke of other determined cause) was 26%, while in the 32 patients with LRLS the percentage of TOAST 4 was significantly higher at 52%(p=0.005) (Table 1). The increase in TOAST 4 in LRLS patients was created by an even distribution of decreases in the other TOAST categories. The most common TOAST 4 stroke etiology in LRLS patients was PFO with concurrent deep venous thrombosis. Conclusion: This preliminary data supports prior studies that have shown superiority of TCD over echocardiography for detection of RLS, and challenge the prevailing notion that extracardiac shunt, such as pulmonary AVM, is the most common cause of LRLS in ischemic stroke patients. This subgroup of patients warrants further research to clarify mechanisms of ischemic stroke in patients with RLS.

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.

Background and Purpose: Providers recognize the need for quick recognition and allocation of resources when ischemic stroke patients arrive at the emergency department. Hemorrhagic stroke patients have not been always given the same priority. One Comprehensive Stroke Center noticed a deficiency in timely recognition, documentation and mobilization of resources for hemorrhagic stroke patients. The initiation of “code head bleed” in the emergency department was created to correct this deficiency. The purpose of this study was to bring awareness and education to the team initially caring for the hemorrhagic stroke patient. Methods: Using Lean methodology, to bring about quality patient care while reducing wasted time, the “code head bleed” was born. Education was provided for all emergency department staff members and physicians regarding “code head bleed.” When a code head bleed notification is paged out it mobilizes all required resources to the patient’s bedside (Faculty physician, Medical Resuscitation team, Patient Care Coordinator, Respiratory Therapy, Stroke Coordinators and Emergency Department leadership). Results: Since its inception in May, the “code head bleed” is the most used code notification in the hospital (n=163 ), surpassing ischemic stroke alerts (n= 89 ) in the same period. An increase of traumatic hemorrhages has been noticed since they are also included in the notification; which has led to an increased awareness in this population of patients as well. Code head bleed has improved neuro-check documentation by 21 % and documentation of vasoactive drip titration by 15% in the hemorrhagic stroke population. Conclusions: In conclusion, having all essential staff, services and resources lends to optimizing the hemorrhagic stroke patient’s care. The “code head bleed” initiative has been attributed to an increased awareness of the needs of the hemorrhagic stroke patient in the emergency department and an improvement in the documentation of care provided.

Background and Purpose: Minimizing time from symptom onset to recanalization is crucial to maximizing outcome. Approaches to save time in ET cases including processes to reduce door-to-recanalization times need to be explored. Methods: We performed a retrospective review of consecutive ischemic stroke patients transferred to our comprehensive stroke center (CSC) from March 2014 to April 2015. Demographic and clinical data were collected. We compared adverse events (hemorrhagic transformation [HT], DVT, PE, urinary tract infection [UTI], pneumonia [PNA], bacteremia), door-to-recanalization time, and short-term outcomes in patients that were evaluated in the emergency department (ED) prior to ET and patients that were transferred directly to the endovascular suite, bypassing the ED. Results: Among the 776 consecutive ischemic stroke patients admitted to our center during the 14-month period, 7% (n=49) received acute ET. Twenty-six of these patients (53%) were transferred to our CSC for ET. Among transfers, 58% (n=15) bypassed the ED. Patients that bypassed the ED had a higher frequency of adverse events (53% vs. 27%, p=0.246), but shorter arrival to recanalization times when compared to patients that did not skip the ED (median 89 vs. 109 minutes p=0.637). Poor functional outcome, as measured by modified Rankin scale (mRS) score of 4-6, was similar between groups (67% vs. 64%, p=1.000), but in-hospital mortality was more frequent in the ED bypass group (33% vs. 18%, p=0.658). Conclusions: In our sample of acute ischemic patients transferred for acute ET, nearly 60% of patients bypassed the ED, reducing time to recanalization. This time savings was associated with a clinically higher proportion of adverse events. Standardized protocols for patients transferred to acute ET are needed to reduce time to recanalization without increasing adverse event rates.

Measurement of quality of stroke care has become increasingly important, but data come mostly from programs in hospitals that choose to participate in certification programs, which may not be representative of the care provided in nonparticipating hospitals. The authors sought to determine differences in quality of care metric concordance for acute ischemic stroke among hospitals designated as a primary stroke center, comprehensive stroke center, and non-stroke center in a population-based epidemiologic study. Significant differences were found in both patient demographics and in concordance with guideline-based quality metrics. These differences may help inform quality improvement efforts across hospitals involved in certification as well as those that are not.

Background Limited national-level information on temporal trends in comprehensive stroke center capabilities and their effects on acute ischemic stroke patients exists. Aims To examine trends in in-hospital outcomes of acute ischemic stroke patients and the prognostic influence of temporal changes in comprehensive stroke center capabilities in Japan. Methods This retrospective study used the J-ASPECT Diagnosis Procedure Combination database and identified 372,978 acute ischemic stroke patients hospitalized in 650 institutions between 2010 and 2016. Temporal trends in patient outcomes and recombinant tissue plasminogen activator (rt-PA) and mechanical thrombectomy usage were examined. Facility comprehensive stroke center capabilities were assessed using a validated scoring system (comprehensive stroke center score: 1–25 points) in 2010 and 2014. The prognostic influence of temporal comprehensive stroke center score changes on in-hospital mortality and poor outcomes (modified Rankin Scale: 3–6) at discharge were examined using hierarchical logistic regression models. Results Over time, stroke severity at admission decreased, whereas median age, sex ratio, and comorbidities remained stable. The median comprehensive stroke center score increased from 16 to 17 points. After adjusting for age, sex, comorbidities, consciousness level, and facility comprehensive stroke center score, proportion of in-hospital mortality and poor outcomes at discharge decreased (from 7.6% to 5.0%, and from 48.7% to 43.1%, respectively). The preceding comprehensive stroke center score increase (in 2010–2014) was independently associated with reduced in-hospital mortality and poor outcomes, and increased rt-PA and mechanical thrombectomy use (odds ratio (95% confidence interval): 0.97 (0.95–0.99), 0.97 (0.95–0.998), 1.07 (1.04–1.10), and 1.21 (1.14–1.28), respectively). Conclusions This nationwide study revealed six-year trends in better patient outcomes and increased use of rt-PA and mechanical thrombectomy in acute ischemic stroke. In addition to lesser stroke severity, preceding improvement of comprehensive stroke center capabilities was an independent factor associated with such trends, suggesting importance of comprehensive stroke center capabilities as a prognostic indicator of acute stroke care.

Background and purpose: In China, stroke center certification was launched in 2015, but little is known about its impact on intravenous thrombolysis. This study aimed to evaluate the effects of stroke center certification on the use of intravenous thrombolysis during a five-year period in South China. Methods: We retrospectively collected data regarding the use of recombinant tissue plasminogen activator (rt-PA) in 21 cities of Guangdong from 2015 to 2020. The annual thrombolysis rate was defined as the number of patients who underwent intravenous rt-PA therapy divided by the number of those who had acute ischemic stroke (AIS) within the same year. The density of stroke centers was calculated as the number of stroke centers divided by the corresponding residents. Spearman’s correlation analysis was used to determine the correlations between the annual thrombolysis rates and the number/density of stroke centers. Paired t-test was used to compare differences in growth in annual thrombolysis rates before and after having stroke center. Results: From 2015 to 2020, the annual rt-PA thrombolysis rates of Guangdong increased from 1.4% to 7.2%, which was accompanied by an increase in the number of stroke centers from 0 to 82 and density of stroke centers from 0.00 to 0.71 per million population. The average annual rt-PA use in stroke centers were higher than that in non-stroke centers from 2016 to 2020 (all P < 0.05). There was a positive correlation of annual thrombolysis rates with the number of stroke centers (r = 1.00, P = 0.0028) and with the density of stroke centers in the 21 cities from 2018 to 2020 (all P < 0.05). The growth in annual thrombolysis rates significantly accelerated at the city-level after having stroke centers (1.55 %/y vs. 0.77 %/y, P < 0.001). Conclusions: Stroke center certification may partially drive the increased use of rt-PA thrombolysis. Stroke center certification should be continually promoted to facilitate access to intravenous thrombolysis for patients with AIS.

AbstractPurposeof review: Tenecteplase has been studied and recommended as an alternative thrombolytic agent in acute stroke patients. A brief review of clinical trials and guidelines pertinent to our clinical decision algorithm is described. This is followed by operational steps that were made to create and implement a clinical pathway based on available evidence in which tenecteplase is used in select stroke patients at our comprehensive stroke center.Recent findings:A number of patients have been treated at our center with IV tenecteplase. A case is presented to illustrate the successful implementation of this new process.Summary:Development of our protocol is discussed in detail in order to enable other centers to create their own clinical pathways for thrombolytic treatment of acute ischemic stroke using tenecteplase.

Background: To date, thrombectomy for large vessel occlusion (LVO) strokes can be performed only in comprehensive stroke centers with thrombectomy capacity. We compared the clinical outcome of patients first referred to a primary stroke center to those admitted directly to a comprehensive stroke center and treated on site in the multicentric observational Endovascular Treatment in Ischemic Stroke (ETIS) registry. Methods: From our perspective, multicenter, observational ETIS registry, we analyzed anterior circulation stroke patients, treated within 8 h, who underwent thrombectomy after thrombolysis and were admitted to a comprehensive stroke center either with drip and ship or mothership. Clinical and safety outcomes were compared between 2 groups. Results: A total of 971 patients were analyzed: 298 were treated with the mothership approach and 673 with drip and ship. Significantly more functional independence (90-day modified Rankin Scale [mRS] 0–2) was achieved in mothership (60.1%) than in drip and ship patients (52.6%; adjusted relative risk [RR] 0.87, 95% CI 0.77–0.98, p = 0.018). Excellent outcome (90-day mRS 0–1) was achieved in 45.3% of the mothership group, compared to 37.9% of the drip and ship group (RR 0.84, 95% CI 0.71–0.98; p = 0.026). According to the distance between the primary stroke center and the comprehensive stroke center, greater functional independence was achieved in mothership than in drip and ship >12.5 miles patients (adjusted RR 0.82; 95% CI 0.71–0.94). Results in the drip-ship group stratified according to time between cerebral imaging and groin puncture (categorized according to the median cut-off: 140 min) were similar. Symptomatic intracerebral hemorrhage rate and mortality within 90 days was similar in both groups (7.5 vs. 5.9%, p = 0.40; 17.4 vs. 16.1%, p = 0.63). Conclusions: Our study suggests that LVO stroke patients directly admitted to a comprehensive stroke center present a higher chance of functional independence, especially when the distance between the primary stroke center and comprehensive stroke center is >12.5 miles or when the time between cerebral imaging and groin puncture is ≥140 min.
