Delayed Intravenous Thrombolysis in Patients with Minor Stroke

Background: The actions and responses of the hospital personnel during acute stroke care in the emergency department (ED) may differ according to the severity of a patient’s stroke symptoms. We investigated whether the time from arrival at ED to various care steps differed between patients with minor and non-minor stroke who were treated with intravenous tissue plasminogen activator (IV tPA). Methods: We included consecutive patients who received IV tPA during a 1.5 year-period in 5 hospitals. Minor stroke was defined as a National Institutes of Health Stroke Scale (NIHSS) score < 5. We compared various intervals from arrival at the ED to treatment between patients with minor stroke and those with non-minor stroke (NIHSS score ≥5). Delayed treatment was defined as a door-to-needle time > 40 min. Results: During the study period, 356 patients received IV tPA treatment. The median door-to-needle time was significantly longer in the minor stroke group than it was in the non-minor stroke group (43 min [interquartile range [IQR] 35.5–55.5] vs. 37 min [IQR 30–46], p < 0.001). The minor stroke group had a significantly longer door-to-notification time (7 min [IQR 4.5–12] vs. 5 min [IQR 3–8], p < 0.001) and door-to-imaging time (20 min [IQR 15–26.5] vs. 16 min [IQR 11–21], p < 0.001) than did the non-minor stroke group. However, the imaging-to-needle time was not different between the groups. Multivariable analyses revealed that minor stroke was associated with delayed treatment (OR 2.54 [95% CI 1.52–4.30], p = 0.001). Conclusions: Our findings show that the door-to-needle time was longer in patients with minor stroke than it was in those with non-minor stroke, mainly owing to delayed action in the initial steps of neurology notification and imaging. Our findings suggest that some quality improvement initiatives are necessary for patients with suspected stroke with minor symptoms.

Introduction: Although Mobile Stroke Treatment Units (MSTU) can reduce time to intravenous thrombolysis (IVtPA), limitations in MSTU care have not been well described. Methods: We retrospectively reviewed consecutive patients transported by MSTU to our academic comprehensive stroke center (CSC) from May 2019 to August 2020 for suspected stroke to assess for potential limitations of care. The Columbus MSTU is owned by a separate health system, but represents a collaborative venture with 3 CSCs and the Columbus Division of Fire, operating daily from 7am-7pm. Data was abstracted on demographics, clinical presentation, last known normal (LKN) time, initial National Institutes of Health Stroke Scale (NIHSS), neuroimaging, and IVtPA administration. Results: Among 93 patients transported to our CSC by MSTU, the mean age was 65 years (range, 21-93) and 61 (66%) were female. The mean initial NIHSS was 7.1 (range, 0 to 33) and 52 (55.9%) had a final diagnosis of stroke (4 hemorrhagic, 48 ischemic). IVtPA was administered in 15 (16.1%) with a mean LKN to IVtPA time of 120 minutes (range, 41 to 243). Among 15 patients treated with IVtPA, 10 received IVtPA in MSTU and 5 in CSC ED. In 7 patients who underwent thrombectomy, mean door to groin time was 57 minutes (range, 28 to 88). Among the overall group, 9 (9.7%) cases were identified with limitations in MSTU care, including 2 patients who received IVtPA by MSTU that were more than 10% off from ideal dosing (underdosed by 9mg and overdosed by 21mg), 1 warfarin-associated hemorrhage requiring intubation who did not receive reversal in MSTU but did upon arrival to CSC ED, and 5 patients who received IVtPA after arrival to CSC ED. The reasons for withholding IVtPA included inability to confirm LKN, patient declination, lack of translator, incorrect LKN, and seizure requiring intubation. The LKN to IVtPA time was significantly longer in the ED compared to MSTU (197 vs 82 minutes, p <0.0001). Conclusion: In our series of suspected stroke patients evaluated by MSTU, gaps identified within MSTU acute stroke care were related to limitations of resources and included errors in weight-based IVtPA dosing, inability to administer IVtPA, or reversal for anti-coagulation related hemorrhage. Clinicians need to be aware of potential pitfalls of MSTU evaluation.

Background:Intravenous tissue plasminogen activator (IV tPA) has been studied primarily in patients over age 50. We sought to describe baseline differences in adult patients ≤50 years-old taken from a large prospective cohort of acute stroke patients treated with intravenous tPA (IV tPA) and to determine whether outcomes differed for this population.Methods:Data (n = 1120) prospectively collected from the Canadian Alteplase for Stroke Effectiveness Study (CASES) were reviewed and patients aged ≤50 years-old (n=99) were compared with those aged >50 years (n=1021) with regards to baseline characteristics, symptomatic intracerebral haemorrhage (sICH), functional outcome at 90 days and death.Results:Nine percent of patients were ≤50 years-old. Among patients aged ≤50 years, 40.4% were women and median age was 42 ± 6.1 years (range 20 to 50). They had significantly more current cigarette use but fewer other vascular risk factors than older patients (p<0.05) and their baseline median NIHSS score was lower (13 versus 15, P=0.001). Although this group was more likely to have a favourable 90-day outcome, multivariable regression confirmed that age ≤50 years, while independently associated with a decreased risk of death (RR 0.36, 95% CI 0.14 to 0.95), was not itself predictive of favourable 90-day outcome or decreased risk of sICH.Conclusions:Adult patients ≤50 years-old had fewer medical co-morbidities and a modestly lower baseline median NIHSS score than their older counterparts. Age ≤50 years was independently associated with a decreased risk of death but not with favourable outcome or risk of sICH.

Background: We sought to evaluate whether the coronavirus disease 2019 (COVID-19) pandemic may have contributed to delays in acute stroke management at Comprehensive Stroke Centers (CSCs). Methods: Pooled clinical data of consecutive adult stroke patients from 12 U.S. CSCs (1/1/2019-5/31/2020) were queried. The rate of thrombolysis for non-transferred patients within the Target: Stroke goal of 60min was compared between patients admitted 3/1/2019-5/31/2019 (pre-COVID-19) and 3/1/2020-5/31/2020 (COVID-19). The time from arrival to imaging and treatment with thrombolysis or thrombectomy, as continuous variables, were also assessed. Results: Of the 7906 patients included, 1319 were admitted pre-COVID-19 and 933 were admitted during COVID-19, 15% of whom underwent intravenous thrombolysis. There was no difference in the rate of thrombolysis within 60min during COVID-19 (OR 0.88, 95%CI 0.42-1.86, p=0.74), despite adjustment for variables associated with earlier treatment (adjusted OR 0.82, 95%CI 0.38-1.76, p=0.61). There was no significant overall delay to thrombolysis during the COVID-19 period vs. pe-COVID-19 (p=0.42), even after multivariable adjustment (p=0.63) or after comparison across months leading to COVID-19 (Figure). The only independent predictor of delayed treatment time between periods was the use of emergency medical services (adjusted β=-6.93, 95%CI -12.83 - -1.04, p=0.03). There was no significant delay from hospital arrival to imaging in all patients, or imaging to skin puncture in patients who underwent thrombectomy. Conclusions: There was no independent effect of the COVID-19 period on delays in acute care with respect to thrombolysis or thrombectomy in this multicenter observational cohort. Further studies are warranted to externally validate these findings, and determine if site volume or center accreditation may mediate a collateral effect of the pandemic on stroke care paradigms.

Background: We evaluated the management, outcome and haemorrhagic risk in a cohort of ischaemic stroke patients with mild symptoms treated with intravenous tissue plasminogen activator (tPA) within the first 4.5 h. Methods: We analysed data from a prospective stroke thrombolysis registry. A total of 1,043 patients received tPA between 2010 and 2014 in the 5 stroke units of the RESUVAL stroke network (Rhône Valley, France). Among them, 170 patients had a National Institute of Health Stroke Scale (NIHSS) score ≤4 (minor group: MG) before tPA and 873 patients had a NIHSS score >4. Results: A high rate (77%) of excellent outcome (3-month-modified Rankin Scale score ≤1) was observed in the MG. No symptomatic intracerebral haemorrhage occurred and the rate of any haemorrhagic transformation was 5%. Fifty-four percent of the MG patients had visible arterial occlusion before tPA. Patients of the MG were less likely to be transported by Emergency Medical Services and to be directly admitted to the stroke unit or to imaging. Median delays from onset to admission, from admission to imaging and from onset to tPA were longer in the MG. Conclusion: Our data provided evidence of safety and suggested potential benefit of thrombolysis in patients with NIHSS score ≤4. A majority of these patients exhibited arterial occlusion before thrombolysis. Most often, patients with mild stroke are not given priority in terms of the mode of transport, direct admission to stroke unit and rapid imaging, resulting in an increased delay from onset to thrombolysis. Health system improvements are needed to provide all suspected stroke victims equal access to imaging and treatment on an emergency basis.

Background: Improved clinical outcomes after intravenous tissue plasminogen activator (IV tPA) are time dependent. Participation in a telestroke program allows the spoke hospitals 24/7 access to a vascular fellowship trained neurologist for a telestroke consult, as well as educational partnership with the hub site, shared protocols, and access to quality improvement feedback. We sought to assess the effects of continued participation in a telestroke program on times to administration of IV tPA. Methods: Our institutional telestroke program began in March 2011 and consists of an academic hub (comprehensive stroke center) that serves 8 community spoke hospitals. We retrospectively reviewed acute ischemic stroke patients treated with IV tPA via the telestroke program. We compared 2 cohorts of patients: Period 1 (July 2011 to June 2013) and Period 2 (July 2013 to July 2014). We collected data on demographics, National Institutes of Health Stroke Scale (NIHSS), and times from initiation of telestroke consult to IV tPA administration. Results: Among 259 consecutive stroke patients (mean: 69.6 years, 56% female) treated with IV tPA via telestroke, the median NIHSS score was 11.8, and 41.7% of patients were transferred to the hub. The mean time from initiation of telestroke consult to IV tPA administration was 42.2 minutes. Period 1 included 129 patients and Period 2 included 130 patients, and the two groups did not differ by age (p=0.2), gender (p=0.3), or NIHSS score (p=0.3). Time from initiation of telestroke consult to IV tPA administration improved from Period 1 to Period 2 (35 vs. 49.9 minutes, p<0.0001). This improvement was due to faster mean time from initiation of telestroke consult to IV tPA advised (12.5 vs. 17.4 minutes, p<0.0001) and faster mean time from IV tPA advised to administration (22.5 vs. 33.1 minutes, p<0.0001). Conclusions: Maturation of a telestroke program is associated with improvement in the timeliness of IV tPA delivery, possibly due to a learning effect that continues the longer the sites participate in the program. This improvement is due to faster responses in both the hub site (recommending IV tPA earlier) and spoke site (administering IV tPA quicker). Further studies aimed at improving delivery of IV tPA in telestroke program are warranted.

Introduction: We analyzed whether the coronavirus disease 2019 (COVID-19) crisis affected acute stroke care in our center during the first 2 months of lockdown in Spain. Methods: This is a single-center, retrospective study. We collected demographic, clinical, and radiological data; time course; and treatment of patients meeting the stroke unit admission criteria from March 14 to May 14, 2020 (COVID-19 period group). Data were compared with the same period in 2019 (pre-COVID-19 period group). Results: 195 patients were analyzed; 83 in the COVID-19 period group, resulting in a 26% decline of acute strokes and transient ischemic attacks (TIAs) admitted to our center compared with the previous year (p = 0.038). Ten patients (12%) tested positive for PCR SARS-CoV-2. The proportion of patients aged 65 years and over was lower in the COVID-19 period group (53 vs. 68.8%, p = 0.025). During the pandemic period, analyzed patients were more frequently smokers (27.7 vs. 10.7%, p = 0.002) and had less frequently history of prior stroke (13.3 vs. 25%, p = 0.043) or atrial fibrillation (9.6 vs. 25%, p = 0.006). ASPECTS score was lower (9 [7–10] vs. 10 [8–10], p = 0.032), NIHSS score was slightly higher (5 [2–14] vs. 4 [2–8], p = 0.122), onset-to-door time was higher (304 [93–760] vs. 197 [91.25–645] min, p = 0.104), and a lower proportion arrived within 4.5 h from onset of symptoms (43.4 vs. 58%, p = 0.043) during the COVID-19 period. There were no differences between proportion of patients receiving recanalization treatment (intravenous thrombolysis and/or mechanical thrombectomy) and in-hospital delays. Conclusion: We observed a reduction in the number of acute strokes and TIAs admitted during the COVID-19 period. This drop affected especially elderly patients, and despite a delay in their arrival to the emergency department, the proportion of patients treated with recanalization therapies was preserved.

Introduction: The risk of ischemic stroke doubles for each decade beyond the age of 55. While disparities, particularly racial disparities, have been described for many aspects of acute stroke care, these disparities have not been well characterized among older adults. The purpose of this analysis was to evaluate potential differences in IV-tPA utilization among acute ischemic stroke (AIS) patients aged ≥65 years. Methods: We used the Nationwide Inpatient Sample (NIS) to examine primary AIS diagnosis discharges (ICD-9 codes 433.x1, 434.x1 and 436) from US hospitals over 2006-2011, among those aged ≥ 65 years. Utilization of IV-tPA was identified using procedure code 99.10. Multivariate logistic regression was conducted to determine age and race associations with IV tPA utilization. Results: Over the 6 year study period, we identified 1.5 million ischemic stroke discharges, with 3.9% receiving IV-tPA. Compared to discharges who did not receive treatment, those receiving IV-tPA were less likely to be female and black. The odds of women receiving IV-tPA were 10% lower than men. After adjusting for demographics, insurance, and medical comorbidities, the odds of women receiving IV-tPA were still 5% lower (Table). When compared to non-black discharges, older blacks were at 25% lower odds of receiving IV-tPA. After adjusting for demographics, insurance and medical comorbidities, older blacks were at 22% lower odds of receiving IV-tPA (Table). Conclusions: Among older Americans, women and blacks have lower odds of being treated with IV-tPA, even after adjusting for age, insurance and comorbidities. A greater understanding of the reasons for these unexplained differences in the fastest growing proportion of our population is needed.

Introduction: The use of mobile electronic care coordination via smartphone technology is a novel approach aimed at increasing efficiency in acute stroke care. One such platform, StopStroke© (Pulsara Inc., Bozeman, MT), serves to coordinate personnel (EMS, nurses, physicians) during stroke codes with real-time digital alerts. This study was designed to examine post-implementation data from multiple medical centers utilizing the StopStroke© application, and to evaluate the effect of method of arrival to ED and time of presentation on these results. Methods: A retrospective analysis of all acute stroke codes using StopStroke© from 3/2013 – 5/2016 at 12 medical centers was performed. Preliminary unadjusted comparison of clinical metrics (door-to-needle time [DTN], door-to-CT time [DTC], and rate of goal DTN) was performed between subgroups based on both method of arrival (EMS vs. other arrival to ED) and time of day. Effects were then adjusted for confounding variables (age, sex, NIHSS score) in multiple linear and logistic regression models. Results: The final dataset included 2589 unique cases. Patients arriving by EMS were older (median age 67 vs. 64, P < 0.0001), had more severe strokes (median NIHSS score 8 vs. 4, P < 0.0001), and were more likely to receive tPA (20% vs. 12%, P < 0.0001) than those arriving to ED via alternative method. After adjustment for age, sex, NIHSS score and case time, patients arriving via EMS had shorter DTC (6.1 min shorter, 95% CI [2, 10.3]) and DTN (12.8 min shorter, 95% CI [4.6, 21]) and were more likely to meet goal DTN (OR 1.83, 95% CI [1.1, 3]). Adjusted analysis also showed longer DTC (7.7 min longer, 95% CI [2.4, 13]) and DTN (21.1 min longer, 95% CI [9.3, 33]), and reduced rate of goal DTN (OR 0.3, 95% CI [0.15, 0.61]) in cases occurring from 1200-1800 when compared to those occurring from 0000-0600. Conclusions: By incorporating real-time pre-hospital data obtained via smartphone technology, this analysis provides unique insight into acute stroke codes. Additionally, mobile electronic stroke care coordination is a promising method for more efficient and efficacious acute stroke care. Furthermore, early activation of a mobile coordination platform in the field appears to promote a more expedited and successful care process.

Background: The use of the National Insitutes of Health Stroke Scale (NIHSS) to assess stroke severity in minor stroke is controversial. We hypothesized that patients with cortical signs on the itemized NIHSS subsets (neglect, visual, or language) will have a worse outcome than those without. Methods: Data was retrieved from the Columbia SPOTRIAS dataset. All patients with NIHSS between 0 and 5 within 12 hours from symptom onset who were not treated with intravenous thrombolysis were included. Patients were followed prospectively as part of the “Stroke Warning Information and Faster Treatment” Study. Poor outcome was defined as not being discharged home and analyzed using multivariable logistic regression. The primary predictor was cortical features on the itemized NIHSS. Individual components of the NIHSS score, treated as a dichotomous variable, as well as the admission NIHSS score were assessed in secondary analyses. Results: The sample included 894 patients, of which 162 (18%) were not discharged home. In multivariable regression analysis of baseline demographics, risk factors, median NIHSS, and cortical signs, only mean age (OR = 1.02, P<0.001) and NIHSS score (OR = 1.59, p<0.001) were associated with non-discharge home. In secondary analyses having any score on the following items predicted non-discharge home: Motor (OR = 2.40, p<0.001), LOC (OR = 6.67, p=0.004), and Ataxia (OR = 3.21, p<0.001). Other items from the NIHSS were not associated with discharge disposition. Motor deficits (AUC 0.623) appeared to be more predictive of discharge outcome than ataxia (AUC 0.569) and LOC deficits (AUC 0.517). In addition, the admission NIHSS had a fair correlation with discharge outcome (AUC 0.683). Conclusion: Deficits in LOC, motor weakness, and ataxia predict discharge outcome in patients with mild stroke, with the motor score being the most influential component. This may potentially alter treatment decisions in this population. The fair correlation between NIHSS score and discharge outcome suggests that certain factors not captured by the NIHSS score may contribute to discharge outcome in this patient population.

Background: Critical access hospitals (CAH) are the first point of stroke care in many rural regions of the United States (US). The Illinois Critical Access Hospital Network (ICAHN), a network of 51 CAH in Illinois, began a quality improvement program to address acute stroke care in 2009. We evaluated the performance on several metrics in acute stroke care at CAH between 2009 and 2011. Methods: Currently, 28 of 51 CAHs in Illinois currently participate in the American Heart Association’s Get With The Guidelines - Stroke (GWTG-S) registry for quality improvement. The GWTG-S registry captured elements including demographics, diagnosis, times of arrival, imaging completion, and intravenous tissue plasminogen activator (IV tPA) administration, and final discharge disposition. We analyzed the change in percent of stroke patients receiving tPA, door-to-needle (DTN) time, and proportion of total stroke patients admitted versus transferred to another facility over the 3 years. Fisher’s exact and Mann-Whitney tests were used as appropriate. Results: In the baseline assessment (2009), there were 111 strokes from 8 sites which grew to 12 sites and 305 strokes in year 1 (2010) and 14 sites and 328 strokes in year 3 (2011). The rate of tPA use for ischemic stroke was 2.2% in 2009, 4.0% in 2010, and 6.2% in 2011 (P=0.20). EMS arrival (41.1%), EMS pre-notification (82.6%), door-to-CT times (median 35 minutes; 34.6% < 25 minutes), and DTN times (average 93 minutes; 13.3% DTN time < 60 minutes) were not different over time. The rate of transfer from CAH to another hospital (51.3%) was constant. Every patient that received tPA except 1 (96.9%) was transferred (drip-ship) for post-tPA care. Conclusions: Improving acute stroke care at CAHs is feasible and represents a significant opportunity to increase tPA utilization in rural areas. As stroke systems develop, it is vital that CAHs be included in quality improvement efforts. The ICAHN stroke collaborative provided the opportunity to coordinate resources, share best practices, participate in targeted educational programming, and utilize data for performance improvement through the funded GWTG-S registry.
