Thrombolytic Treatment

BACKGROUND: Despite the recent emphasis on protocols for emergent triage and treatment of in-hospital acute ischemic stroke, there is little data on rates and outcomes of patients receiving thrombolytics for in-hospital ischemic strokes. OBJECTIVE: To determine the rates of in-hospital ischemic stroke treated with thrombolytics and to compare outcomes with patients treated with thrombolytics on admission. DESIGN/METHODS: We analyzed a seven-year data (2002-2009) from the National Inpatient Survey (NIS), a nationally representative inpatient database in the United States. We identified patients who had in-hospital ischemic strokes (defined by thrombolytic treatment after one day of hospitalization) and those who received thrombolytics on the admission day. We compared demographics, baseline clinical characteristics, in hospital complications, length of stay, hospitalization charges, and discharge disposition, between the two patient groups. RESULT: A total of 18036 (21.5%) and 65912 (78.5%) patients received thrombolytics for in-hospital and on admission acute ischemic stroke, respectively. In hospital complications such as pneumonia (5.0% vs. 3.4%, p=0.0006), deep venous thrombosis (1.9% vs. 0.6%, p<0.0001) and pulmonary embolism (0.8% vs. 0.4%, p=0.01) were significantly higher in the in-hospital group compared to on admission thrombolytic treated group. Hospital length of stay and mean hospital charges were not different between the two groups. Patients who had in-hospital strokes had had higher rates of in hospital mortality (12.1% vs. 10.6%, p=0.02). In a multivariate analysis, in-hospital thrombolytic treated group had higher in-hospital mortality after adjustment for age, gender and baseline clinical characteristics (odds ratio 0.84, 95% confidence interval 0.74-0.95, p=0.008). CONCLUSION/RELEVANCE: In current practice, one out of every five acute ischemic stroke patients treated with thrombolytics is receiving treatment for in-hospital strokes. The higher mortality and complicated hospitalization in such patients needs to be recognized.

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.

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: The benefits of tPA (tissue-type plasminogen activator) in acute ischemic stroke are time-dependent. However, delivery of thrombolytic therapy rapidly after hospital arrival was initially occurring infrequently in hospitals in the United States, discrepant with national guidelines. Methods: We evaluated door-to-needle (DTN) times and clinical outcomes among patients with acute ischemic stroke receiving tPA before and after initiation of 2 successive nationwide quality improvement initiatives: Target: Stroke Phase I (2010–2013) and Target: Stroke Phase II (2014–2018) from 913 Get With The Guidelines-Stroke hospitals in the United States between April 2003 and September 2018. Results: Among 154 221 patients receiving tPA within 3 hours of stroke symptom onset (median age 72 years, 50.1% female), median DTN times decreased from 78 minutes (interquartile range, 60–98) preintervention, to 66 minutes (51–87) during Phase I, and 50 minutes (37–66) during Phase II ( P <0.001). Proportions of patients with DTN ≤60 minutes increased from 26.4% to 42.7% to 68.6% ( P <0.001). Proportions of patients with DTN ≤45 minutes increased from 10.1% to 17.7% to 41.4% ( P <0.001). By the end of the second intervention, 75.4% and 51.7% patients achieved 60-minute and 45-minute DTN goals. Compared with the preintervention period, hospitals during the second intervention period (2014–2018) achieved higher rates of tPA use (11.7% versus 5.6%; adjusted odds ratio, 2.43 [95% CI, 2.31–2.56]), lower in-hospital mortality (6.0% versus 10.0%; adjusted odds ratio, 0.69 [0.64–0.73]), fewer bleeding complication (3.4% versus 5.5%; adjusted odds ratio, 0.68 [0.62–0.74]), and higher rates of discharge to home (49.6% versus 35.7%; adjusted odds ratio, 1.43 [1.38–1.50]). Similar findings were found in sensitivity analyses of 185 501 patients receiving tPA within 4.5 hours of symptom onset. Conclusions: A nationwide quality improvement program for acute ischemic stroke was associated with substantial improvement in the timeliness of thrombolytic therapy start, increased thrombolytic treatment, and improved clinical outcomes.

Geographic Distribution of Acute Ischemic Stroke admissions in the United States Background: The geographic distribution of acute ischemic stroke in the United States has not been evaluated, unlike the association shown with acute MI by Patel et al., (International Journal of Cardiology, 2014, 172.3). Our study looked at the geographic distribution and seasonal variation of acute ischemic stroke using the National Inpatient Sample (NIS) from 2011 - 2013. Methods: Adult admissions with a primary diagnosis of acute ischemic stroke were extracted from the NIS database using the ICD 9 code 434.91 from 2011 - 2013. Admission information included hospital region (West, South, Mid-Atlantic and Northwest) and seasonal admission rates (Winter=December-February, Spring=March-May, Summer=June-August, Fall=September-November). A Chi square analysis was used to analyze differences in categorical variables (we assumed a normal distribution of 25% per region). Results: A total of 120714 admissions were identified (weighted = 603361). There were more cases of acute ischemic stroke in the South (41.52 percent of admissions) compared to the mid Atlantic (21.4), Northwest (17.98) or West (19.08) with a p value < 0.0001. Each year between 2011 to 2013 showed a higher rate of admissions for acute ischemic stroke in the South. Taking the years into summation showed no statistically significant difference in seasonal variation in any of the regions. Conclusion: Our study shows a higher number of admissions for acute ischemic stroke in the South, but failed to show any seasonal differences. However, there are several studies that suggest a preponderance of admissions for acute myocardial infarction during the winter season, Spencer et al., (Journal of the American College of Cardiology, 1998, 31.2.) Further studies are needed to identify why there is a significant regional difference in the admission rates for acute ischemic stroke.
