Background: While single center and regional estimates of thrombolytic administration using drip and ship treatment paradigm are available, patient outcomes, thrombolytic utilization, cost, and referral patterns has not been assessed in United States. Objective: To provide national estimates of patients treated with thrombolytics using drip and ship paradigm and determine the impact of drip and ship treatment on regional thrombolytic utilization, treatment cost, and referral patterns of acute stroke patients in a large cohort. Methods: We determined the proportion of patients treated with drip and ship paradigm among all acute ischemic stroke patients treated with thrombolytic treatment and obtained comparative in-hospital outcomes from the Nationwide Inpatient Survey (NIS) data files from October 2008 to December 2009. All the in-hospital outcomes were analyzed after adjusting for potential confounders using multivariate analysis. Thrombolytic utilization, hospitalization cost, and patterns of referral related to drip and ship treatment of acute stroke were estimated. Results: Of the 26,814 ischemic stroke patients who received thrombolytic treatment, 5144 (19%) were treated using drip and ship paradigm. Seventy nine percent of all the drip and ship treated patients were referred to urban teaching hospitals for further care, and 7% of them received follow up endovascular treatment at the referral facility. States with higher proportion of patients treated using the drip and ship paradigm had higher rates of thrombolytic utilization (3.1% vs. 2.4%, p<0.001). After adjusting for age, gender, presence of hypertension, diabetes mellitus, renal failure, and hospital teaching status, outcomes of patients treated with drip and ship paradigm was similar to those who received thrombolytic and stayed in the same facility: self care (odds ratio [OR], 1.055, 95% confidence interval [CI], 0.910-1.224, p=0.4779); death(OR , 0.821 95% CI, 0.619- 1.088, p=0.1688); and nursing home discharge (OR, 1.023, 95% CI, 0.880- 1.189, p=0.7659) at discharge. Drip and ship paradigm was associated with shorter hospital stay (mean [days, SE] 5.9± 0.18 vs. 7.4 ± 0.15, p<0.001), and lower cost of hospitalization (mean total charges [$, SE) 57,000 ± 3,324 vs. 83,000 ± 3,367, p<0.001). Conclusions: One out of every five patients who received thromboytic treatment in United States is currently treated using drip and ship paradigm with comparable adjusted rates of favorable outcomes. There was a higher rates of thrombolytic utilization in States where drip and ship was more commonly implemented.

Introduction: Several studies have shown improved outcomes in ischemic stroke patients treated with mechanical thrombectomy in clinical trials after introduction of stent retrievers. The outcomes of patients undergoing endovascular treatment in general practice are expected to improve. We performed this analysis to evaluate trends in utilization of endovascular treatment in acute ischemic stroke and associated rates of death and disability in real world practice. Methods: We obtained data for patients admitted with primary diagnosis of ischemic stroke in United States from 2009-2016 using Nationwide Inpatient Sample. We determined the rate and pattern of utilization, and associated in-hospital outcomes of endovascular treatment among them. Outcomes were classified as minimal disability, moderate to severe disability, and death based on discharge disposition and compared between two time periods: 2009-2011 and 2013-2016 to represent pre and post stent retriever approvals in United States. Results: Of the 3,780,955 patients admitted with ischemic stroke, 244,092 (6.46%) received intravenous thrombolytic treatment, and 48,409 (1.28%) underwent endovascular treatment. There was a fourfold increase in patients who underwent endovascular treatment (0.55% of ischemic strokes in 2009 vs. 2.03% in 2016, trend p < 0.001). In multivariate logistic regression analysis, adjusted for age, gender, thrombolytic therapy, in hospital complications including secondary intracranial hemorrhages, the rate of none to minimal disability improved between the two study intervals (2009-2011 versus 2013-2016), odds ratio (OR) 1.82, 95% confidence interval (CI) 1.47-2.67, p=<0.0001) and moderate to severe disability decreased (OR 0.56, 95% CI 0.45- 0.70, p= <0.0001). There was significant decrease inpatient mortality for patients treated during 2013-2016; OR 0.67, 95% CI 0.56- 0.79, p= <0.0001). Conclusion: There has been a significant increase in the proportion of acute ischemic stroke patients receiving endovascular treatment with improvement of outcomes. Our analysis support generalizability of the successful results observed in clinical trials of endovascular treatment in the post-stent retriever approval era in United States.

Background and Purpose: The drip and ship paradigm has rapidly expanded in the last decade allowing higher thrombolytic utilization and endovascular treatment. We performed this analysis to evaluate trends in utilization of drip and ship paradigm in United States and associated outcomes. Methods: We analyzed data for patients admitted with primary diagnosis of ischemic stroke in the United States from Nationwide Inpatient Sample, the largest nationally representative data, for the years 2009 to 2015. We studied changes in utilization of drip-and-ship paradigm and subsequent performance of endovascular treatment, and rates of discharge with none to minimal disability and moderate to severe disability. Results: Of the 3,043,190 patients admitted with ischemic stroke, 56,449 (1.85%) patients received thrombolytic treatment through drip-and-ship paradigm over a 7 year period. Of all patients who received thrombolytic treatment (n=243,824), 56,449 (23.15%) received using drip and ship paradigm. There was almost 3 fold increase in drip and ship paradigm (in 0.98% 2009 to 2.80% in 2015 (test for trend= p < 0.001). Among the patients who underwent drip and ship paradigm, 5,061 (8.97%) underwent endovascular treatment. The rate of endovascular treatment increased from 6.62% to 12.39% among patients treated with drip and ship paradigm (test for trend= p < 0.001). The rate of none minimal disability at discharge increased from 39.93% to 47.08%, (test for trend p < 0.001) while moderate to severe disability decreased 51.22% to 47.08%, (test for trend p < 0.001) in ischemic stroke patients treated using drip-and-ship paradigm. Similar trends were observed for hospital outcomes in multivariate logistic regression model, adjusted for age, gender, medical comorbidities and secondary intracranial hemorrhages. Conclusion: There has been a significant increase in the proportion of acute ischemic stroke patients treated using drip-and-ship paradigm (out of proportion to overall thrombolytic use) with increase in subsequent endovascular treatment in United States. The in hospital outcomes of patients have improved perhaps due to higher utilization of endovascular treatment.

Background and Purpose: Hemicraniectomy is carefully selected for patients with acute ischemic stroke in whom endovascular treatment has failed to prevent adverse outcomes of large hemispheric stroke. We evaluated trends in the utilization of hemicraniectomy in patients who underwent endovascular therapy according to the availability of three generations of thrombectomy devices and analyzed the associated rates of death and disability among them over a nine year period. Methods: We obtained data for patients admitted to hospitals in the United States from 2004 to 2012 with a primary diagnosis of ischemic stroke using a large national database. We determined the rate and pattern of hemicraniectomy utilization, and associated in-hospital outcomes of endovascular treatment among ischemic stroke patients. Outcomes were compared between three time periods: 2004-2006 (post MERCI), 2007-2009 (post Penumbra) and 2010-2012 (post Solitaire stent retriever) approvals. Results: Of the 6,021,636 patients admitted with ischemic stroke, 28,956 (0.48%) underwent endovascular treatment. Of the patients who underwent endovascular therapy, 2,219 (7.6%) required subsequent hemicraniectomy. There was a 7 fold decrease in the utilization of hemicraniectomy in these patients between 2004 and 2009 (25.6% in 2004 vs. 3.5% in 2009, p < 0.001) with a yearly trend towards decreased utilization of hemicraniectomy [OR 0.7, 95% CI 0.6- 0.8, p <.0001]. In multivariate logistic regression analysis there was a reduction in the rate of in hospital mortality of the 2007-2009 and the 2010-2012 groups when compared to the 2004-2006 interval group (2007-2009, odds ratio (OR) 0.9, 95% confidence interval (CI) (0.7- 1.2) and 2010-2012, [OR 0.9, 95%CI 0.7- 1.1]). The rate of moderate to severe disability increased for patients treated during 2007-2009 and 2010-2012. Conclusion: In the last 9 years there has been a significant decrease in the utilization of hemicraniectomy in acute ischemic stroke patients who underwent endovascular treatment. Despite reduction in use of hemicraniectomy, the mortality rate in endovascularly treated patients have shown a reduction, but there was an increase in rate of moderate to severe disability.

Background: Several studies suggest women may be disproportionately affected by poorer stroke outcomes than men. This study aims to investigate whether women have a higher risk of all-cause mortality and recurrence after an ischemic stroke than men in a rural population in central Pennsylvania, United States. Methods: We analyzed consecutive ischemic stroke patients captured in the Geisinger NeuroScience Ischemic Stroke research database from 2004 to 2019. Kaplan–Meier (KM) estimator curves stratified by gender and age were used to plot survival probabilities and Cox Proportional Hazards Ratios were used to analyze outcomes of all-cause mortality and the composite outcome of ischemic stroke recurrence or death. Fine–Gray Competing Risk models were used for the outcome of recurrent ischemic stroke, with death as the competing risk. Two models were generated; Model 1 was adjusted by data-driven associated health factors, and Model 2 was adjusted by traditional vascular risk factors. Results: Among 8900 adult ischemic stroke patients [median age of 71.6 (interquartile range: 61.1–81.2) years and 48% women], women had a higher crude all-cause mortality. The KM curves demonstrated a 63.3% survival in women compared with a 65.7% survival in men ( p = 0.003) at 5 years; however, the survival difference was not present after controlling for covariates, including age, atrial fibrillation or flutter, myocardial infarction, diabetes mellitus, dyslipidemia, heart failure, chronic lung diseases, rheumatic disease, chronic kidney disease, neoplasm, peripheral vascular disease, past ischemic stroke, past hemorrhagic stroke, and depression. There was no adjusted or unadjusted sex difference in terms of recurrent ischemic stroke or composite outcome. Conclusion: Sex was not an independent risk factor for all-cause mortality and ischemic stroke recurrence in the rural population in central Pennsylvania.
