BACKGROUND Early administration of intravenous tissue plasminogen activator (IV alteplase) improves functional outcomes in patients with acute ischemic stroke, yet many patients are not treated with IV alteplase. There is a need to understand the reasons for nontreatment and the short‐ and long‐term outcomes in this patient population. METHODS We analyzed patients ≥65 years old with a primary diagnosis of acute ischemic stroke presenting within 24 hours of time last known well (LKW) but not treated with IV alteplase from 1630 Get With The Guidelines‐Stroke hospitals in the United States between January 2016 and December 2016. We report clinical characteristics, reasons for withholding treatment, in‐hospital mortality, and 90‐day and 1‐year outcomes including costs, stratified by time from LKW to presentation (≤4.5, >4.5–6, and >6–24 hours). RESULTS Of 39 760 patients (median age 80 [25th–75th quartiles: 73–87], 56.7% female), 19 391 (48.8%) presented within 4.5 hours of LKW. In those with documented reasons for withholding IV alteplase, the most common reasons were rapid improvement of symptoms (3985/14 782, 27.0%) and mild symptoms (3791/14 782, 25.6%). In 1100 out of 1174 (93.7%) patients presenting in the >3.0‐ to 4.5‐hour time window, the most common reason for not treating was a delay in patient arrival. The most common discharge location for those presenting ≤4.5 hours since LKW was home (8660/19 391, 44.7%). The 90‐day mortality and readmission rates were 18.9% and 23.0% in those presenting ≤4.5 hours since LKW, 19.0% and 22.2% in those presenting between 4.5 and 6 hours, and 19.1% and 23.2% in those presenting between 6 and 24 hours. Median 90‐day total in‐hospital costs remained relatively high at $9471 (Q25–Q75: $5622–$21 356) in patients presenting ≤4.5 hours since LKW. CONCLUSIONS Patients within the Get With The Guidelines‐Stroke registry not treated with IV alteplase have a high risk of readmission and mortality and have high total in‐hospital and postdischarge costs. This study may inform future efforts to address the unmet need to improve the scope of IV alteplase delivery along with other aspects of acute ischemic stroke care and, consequently, outcomes in this patient population.

Background: Many patients are transferred from emergency departments or inpatient units to stroke centers for advanced acute ischemic stroke (AIS) care, especially after intravenous tissue plasminogen activator (tPA). We sought to determine variation in the rates of AIS patient transfer in the US. Methods: Using data from the national Get With The Guidelines-Stroke registry, we analyzed AIS cases from 01/2010 to 03/14. Transfer-in was defined as transfer of AIS patients from other hospitals. Due to large sample size, instead of p-values, standardized differences were reported and a map of transfer-in rates across the US constructed. Results: Of the 970,390 patients discharged from 1,646 hospitals in the US, 87% were admitted via the ER or direct admission (front door) vs. 13% transferred-in. While most hospitals (61%) had transfer-in rates of < 5% of all AIS patients, a minority (17%) had high (>15%) transfer-in rates. High transfer-in hospitals were more often in the Midwest, were larger, and had higher annual AIS and IV tPA case volumes, and were also more often teaching hospitals and stroke centers (primary or comprehensive) (Table and Figure).. IV tPA was used more frequently in eligible patients in high-volume transfer-in hospitals (Table); otherwise, stroke quality of care was similar. Conclusions: There is significant regional- and state-level variability in the transfer of AIS patients. This may reflect differences in resource availability and the distribution of smaller, under-resourced hospitals that frequently transfer patients for advanced care after stabilization. Additional research is warranted to understand this variation.

Background: The benefits of intravenous tissue-plasminogen activator (tPA) in acute ischemic stroke are time-dependent. Emergency medical services (EMS) pre-notification of stroke arrivals may provide a means of reducing evaluation and treatment times. In this study we used data from the nationwide Get With The Guidelines Stroke (GWTG-Stroke) program to determine the effect of EMS pre-notification on acute ischemic stroke processes of care. Methods: Acute ischemic stroke patients transported by EMS to 1585 GWTG-Stroke hospitals from April 2003 to March 2011 were studied. The association between EMS pre-notification and door-to-imaging (DTI) times, door-to-needle (DTN) times, onset-to-needle times (OTN), and tPA treatment rates were analyzed using multivariable GEE regression analyses. Results: Of 371,988 EMS transported acute ischemic stroke patients, EMS pre-notification occurred in 249,197 (67.0%). Patients with pre-notification had shorter door-to-imaging times, shorter onset-to-needle times, and were more likely to be treated with tPA when eligible ( Table ). EMS pre-notification was independently associated with increased odds of DTI ≤25 minutes (adjusted OR 1.53, 95% CI 1.44–1.63, p<0.0001), DTN times ≤60 minutes (aOR 1.20, 95% CI 1.10–1.31, p<0.0001), OTN times (aOR 1.17, 95% CI 1.09–1.25, p<0.0001), and tPA use within 3 hours among eligible patients arriving by 2 hours (aOR 1.64, 95% CI 1.50–1.79, p<0.0001), without significant increases in complications of thrombolytic therapy. Conclusion: EMS pre-notification is independently associated with more rapid patient imaging and increased timeliness in IV tPA administration. These results support the need for initiatives targeted at increasing EMS pre-notification rates as a mechanism from improving quality of care and outcomes in acute ischemic stroke.

Background: Despite proven efficacy of intravenous tissue plasminogen activator (tPA) and endovascular thrombectomy (EVT) in acute ischemic stroke, there has been slow administration of these therapies in the real world practice. We examined the ongoing quality improvement in acute stroke care at our comprehensive stroke center. Methods: Consecutive patients with acute ischemic stroke from 2013 to 2018 were studied. Patients were managed using Code Stroke algorithm per concurrent AHA guidelines and a simple quality improvement protocol implemented in 2015. Demographics and clinical data were collected from Get-With-The-Guideline-Stroke registry and electronic medical records. Patients were divided into 3 groups per admission and implementation date of quality improvement initiatives. Quality measures, including rates of intravenous tPA and EVT, door-to-needle (DTN) time, and door-to-puncture (DTP) time, were analyzed with general mean linear regression models and Jonckheere-Terpstra test. Results: Of the 1,369 eligible patients presenting within 24 hours of symptom onset or wakeup stroke, the rate of intravenous tPA was 20%, 30% and 22%, respectively, in 2013-2014, 2015-2016, and 2017-2018. In contrast, EVT rate was 9%, 14% and 15%, respectively. Based on Jonckheere-Terpstra test, there was significant ongoing improvement in the median DTN time (57, 45, 39 minutes; p < 0.001) and DTP time (172, 130, 114 minutes; p =0.009) during the 3 time periods, with DTN time ≤ 60 and ≤45 minutes in 80% and 63% patients, respectively, in 2017-2018. Conclusions: Getting with the guidelines and simple quality improvement initiatives are associated with satisfactory rates of acute stroke therapy and ongoing improvement in door to treatment times.

Background: The current recommended dose of intravenous tissue plasminogen activator (IV rt-PA) for ischemic stroke patients weighing >100 kg is fixed at 90 mg and thus obese patients receive less than the recommend 0.9mg/kg dosage. We hypothesized that obese patients receive a lower dose of thrombolytics and they will have a lower rates of intracerebral hemorrhages (ICH), but lower rates of clinical benefit from IV rt-PA. Objective: To determine the relationship between obesity and clinical outcomes among acute ischemic stroke patients receiving IV rt-PA. Methods: Data were obtained from all states within the United States that contributed to the Nationwide Inpatient Sample. All patients admitted to US hospitals between 2002 and 2009 with a primary discharge diagnosis of stroke treated with IV thrombolysis (identified by the International Classification of Diseases, Ninth Revision procedure codes) were included. We analyzed whether the presence of obesity was associated with clinical outcome and ICH with multivariate logistic regression analysis after adjusting for potential confounders. Results: Of the 84,727 patients with ischemic stroke treated with IV rt-PA, 5,437 (6.4%) had concurrent obesity. The ICH rates between obese and non-obese patients was 4.3% versus 6.1% (p=0.005). After adjusting for age, sex, hypertension, diabetes mellitus, renal failure, hospital teaching status, and ICH, the presence of obesity was not associated with increased rates of self-care (odds ratio [OR] 0.929, 95% confidence interval [CI] 0.815-1.063, p=0.27), but was associated with decreased rates of mortality (OR 0.78, 95% CI 0.61 - 0.94, p=0.045) at discharge. Conclusion: Obese patients undergoing IV t-PA treatment for acute ischemic stroke appear to have lower rates of ICHs and mortality presumably due to lower weight adjusted thrombolytic dose.

Reperfusion Strategy

Stroke is the third leading cause of death in the United States and the number one cause of adult long-term disability. Disability in stroke survivors includes hemiparesis, aphasia, inability to walk without assistance, dependence on others for activities of daily living, depression, and institutionalization. Immediate recognition of acute ischemic stroke (AIS) signs and symptoms is required because many treatment options are time sensitive. Hospital transport via activation of 911 and emergency medical services (EMSs) removes delays to urgent diagnosis and intervention. Intravenous (IV) recombinant tissue plasminogen (rt-PA) is a time-sensitive reperfusion strategy. The American Heart Association (AHA) and American Stroke Association (ASA) recently revised recommendations that the time window for IV rt-PA be expanded from 3 hours to 4.5 hours after symptom onset in patients with mild to moderate stroke. Supportive therapies include crystalloid IV solutions, adequate oxygenation, and normothermia. Best rest is desired along with oxygen supplementation. Avoidance of fever is paramount since fever can contribute to negative outcomes. It is the purpose of this article to review risk factors, stroke symptoms, epidemiology, and current drug therapy of AIS. Standards of care will be reviewed.

Background Less than 40% of acute stroke patients have computed tomography (CT) imaging performed within 25 minutes of hospital arrival. We aimed to examine the race‐ethnic and sex differences in door‐to‐CT (DTCT) ≤25 minutes in the FSR (Florida Stroke Registry). Methods and Results Data were collected from 2010 to 2018 for 63 265 patients with acute ischemic stroke from the FSR and secondary analysis was performed on 15 877 patients with intravenous tissue plasminogen activator‐treated ischemic stroke. Generalized estimating equation models were used to determine predictors of DTCT ≤25. DTCT ≤25 was achieved in 56% of cases of suspected acute stroke, improving from 36% in 2010 to 72% in 2018. Women (odds ratio [OR], 0.90; 95% CI, 0.87–0.93) and Black (OR, 0.88; CI, 0.84–0.94) patients who had strokes were less likely, and Hispanic patients more likely (OR, 1.07; CI, 1.01–1.14), to achieve DTCT ≤25. In a secondary analysis among intravenous tissue plasminogen activator‐treated patients, 81% of patients achieved DTCT ≤25. In this subgroup, women were less likely to receive DTCT ≤25 (0.85, 0.77–0.94) whereas no significant differences were observed by race or ethnicity. Conclusions In the FSR, there was considerable improvement in acute stroke care metric DTCT ≤25 in 2018 in comparison to 2010. However, sex and race‐ethnic disparities persist and require further efforts to improve performance and reduce these disparities.

ObjectiveTo determine whether young adults (≤40 years old) with acute ischemic stroke are less likely to receive IV tissue plasminogen activator (tPA) and more likely to have longer times to brain imaging and treatment.MethodsWe analyzed data from the Get With The Guidelines–Stroke registry for patients with acute ischemic stroke hospitalized between January 2009 and September 2015. We used multivariable models with generalized estimating equations to evaluate tPA treatment and outcomes between younger (age 18–40 years) and older (age >40 years) patients with acute ischemic stroke.ResultsOf 1,320,965 patients with acute ischemic stroke admitted to 1,983 hospitals, 2.3% (30,448) were 18 to 40 years of age. Among these patients, 12.5% received tPA vs 8.8% of those >40 years of age (adjusted odds ratio [aOR] 1.63, 95% confidence interval [CI] 1.56–1.71). However, younger patients were less likely to receive brain imaging within 25 minutes (62.5% vs 71.5%, aOR 0.78, 95% CI 0.73–0.84) and to be treated with tPA within 60 minutes of hospital arrival (37.0% vs 42.8%, aOR 0.74, 95% CI 0.68–0.79). Compared to older patients, younger patients treated with tPA had a lower symptomatic intracranial hemorrhage rate (1.7% vs 4.5%, aOR 0.55, 95% CI 0.42–0.72) and lower in-hospital mortality (2.0% vs 4.3%, aOR 0.65, 95% CI 0.52–0.81).ConclusionsIn contrast to our hypothesis, younger patients with acute ischemic stroke were more likely to be treated with tPA than older patients, but they were more likely to experience delay in evaluation and treatment. Compared with older patients, younger patients had better outcomes, including fewer intracranial hemorrhages.
