P239 BACKGROUND: Whether admission of stroke patients to neurologists is associated with improved outcomes is uncertain. Though prior studies suggested ischemic stroke patients under the care of neurologists had lower rates of in-hospital mortality than those treated by internists, these studies were uncontrolled for the possibility that patients with better prognosis were admitted to neurologists. METHODS: The University HealthSystem Consortium administrative database contains patient information from 84 large academic health centers and associates. Discharge abstracts for ischemic strokes admitted through emergency rooms 1997–1999 were obtained. Database variables were validated by comparison with a detailed chart review of 927 patients at 36 institutions. Attending physician specialty was evaluated as a predictor of in-hospital mortality using chi-square statistics and multivariable logistic regression. To determine whether hospital rates of stroke admission to neurologists were predictive of in-hospital mortality, generalized estimating equations (GEE) were used. This multivariable method accounts for clustering of observations at institutions, which broadens confidence intervals (CI). All multivariable analyses were adjusted for age, gender, race, admission status, and treatment volume. RESULTS: Of 28,571 ischemic strokes admitted through the emergency department, 58% were admitted to neurologists. Univariate analyses demonstrated a lower risk of in-hospital mortality in cases admitted to neurologist (4.7%) compared to non-neurologists (9.4%; p<0.001). Adjustment for case-mix did not alter the association (odds ratio, 0.48; 95% CI, 0.43–0.53; p<0.001). However, risk of death was not lower at hospitals admitting a larger portion of ischemic stroke cases to neurologists (p=0.54) as would be expected if admission to neurologists led to improved outcomes. CONCLUSIONS: In academic medical centers, ischemic stroke patients admitted to neurologists are less likely to die in the hospital compared to those admitted to other services. However, this may be due to selection of patients with better prognosis for admission to neurologists.

Background and purpose: In-hospital stroke-onset assessment and management present numerous challenges, especially in community hospitals. Comprehensive analysis of key stroke care metrics in community-based primary stroke centers is under-studied. Methods: Medical records were reviewed for patients admitted to a community hospital for non-cerebrovascular indications and for whom a stroke alert was activated between 2013 and 2019. Demographic, clinical, radiologic and laboratory information were collected for each incident stroke. Descriptive statistical analysis was employed. When applicable, Kruskal-Wallis and Chi-Square tests were used to compare median values and categorical data between pre-specified groups. Statistical significance was set at alpha = 0.05. Results: There were 192 patients with in-hospital stroke-alert activation; mean age (SD) was 71.0 years (15.0), 49.5% female. 51.6% (99/192) had in-hospital ischemic and hemorrhagic stroke. The most frequent mechanism of stroke was cardioembolism. Upon stroke activation, 45.8% had ischemic stroke while 40.1% had stroke mimics. Stroke team response time from activation was 26 minutes for all in-hospital activations. Intravenous thrombolysis was utilized in 8% of those with ischemic stroke; 3.4% were transferred for consideration of endovascular thrombectomy. In-hospital mortality was 17.7%, and the proportion of patients discharged to home was 34.4% for all activations. Conclusion: The in-hospital stroke mortality was high, and the proportions of patients who either received or were considered for acute intervention were low. Quality improvement targeting increased use of acute stroke intervention in eligible patients and reducing hospital mortality in this patient cohort is needed.

Long Term Mortality

Background: Cerebral microbleeds (CMBs) were predictive of mortality in elderly and considered as a putative marker for risk of intracranial hemorrhage. Stroke patients with non valvular atrial fibrillation (NVAF) require anticoagulation, which increases the risk of hemorrhages. We investigated association of CMBs with the long term mortality in acute ischemic stroke patients with NVAF. Methods: During 6 years , consecutive ischemic stroke patients who had NVAF and who had undergone brain MRI with a gradient-recalled echo sequence were enrolled. Long-term mortality and causes of death were identified using data from Korean National Statistical Office. Survival analysis was performed whether the presence, number and location of CMBs were related with all causes, cardiovascular, and cerebrovascular mortality during follow-up. Results: Total 506 patients were enrolled during the study period and were followed up for median 2.5 years. CMBs were found in 30.8% of patients (156/506). Oral anticoagulation with warfarin was prescribed at discharge in 477 (82.7%) patients. During follow up, 177 (35%) patients died and cerebrovascular death was noted in 93 patients (81 ischemic stroke and 12 hemorrhagic stroke). After adjusting age, sex and significant variables in univariate analysis (p<0.1), multiple CMBs (≥5) were the independent predictor for all-cause, cardiovascular and ischemic stroke mortalities. The strictly lobar CMBs were associated with hemorrhagic stroke mortality in multivariate Cox regression analysis (HR 4.776, p=0.032) (Figure 1). Conclusions: Multiple CMBs were the independent predictor for the long term mortality in stroke patients with NVAF. Among them, patients with strictly lobar CMBs had a high risk of death due to hemorrhagic stroke. Our findings suggest that detection of CMBs in stroke patients with NVAF are of clinical relevance for predicting long term outcome and that particular concern is necessary in those with strictly lobar CMBs for their increased risk of death due to hemorrhagic stroke.

Shared Risk

Background: COPD recently overtook stroke as the third leading cause of death in the United States. Intriguingly, smoking is an important shared risk factor for both stroke and COPD; COPD patients have baseline cerebral hypoxia and hypercapnia that could potentially exacerbate vascular brain injury; and stroke patients with COPD are at higher risk of aspiration than those without COPD. Yet, relatively little is known about the prevalence of COPD among stroke patients or its impact on outcomes after an index stroke. Objective: To assess prevalence of COPD among hospitalized stroke patients in a nationally representative sample and examine the effect of COPD with risk of dying in the hospital after a stroke. Methods: Data were obtained for patients, 18 years and older, from the National Inpatient Sample from 2004-2009 (n=48,087,002). Primary discharge diagnoses of stroke were identified using ICD-9 diagnosis codes 430-432 and 433-436, of which a subset with comorbid COPD were defined with secondary ICD-9 diagnoses codes 490-492, 494, and 496. In-hospital mortality rates were calculated, and independent associations of COPD with in-hospital mortality following stroke were evaluated with logistic regression. All analysis were survey-weighted. Results: 11.71% (95% CI 11.48-11.94) of all adult patients hospitalized for stroke had COPD. The crude and age-adjusted in-hospital mortality rates for these patients were 6.33% (95% CI 6.14-6.53) and 5.99% (95% CI 4.05-7.94), respectively. COPD was independently and modestly associated with overall stroke mortality (OR 1.03, 95% CI 1.01-1.06; p=0.02). However, when analyzed by subtype, greater risks of mortality were seen in those with intracerebral hemorrhage (OR 1.12, 95% CI 1.03-1.20; p<0.01), and ischemic stroke (OR 1.08; 95% CI 1.03-1.13, p<0.01), but not subarachnoid hemorrhage (OR 0.98, 95% CI 0.85-1.13; p=0.78). There were no statistically significant interactions between COPD and age, gender, or race. Conclusion: 12% of hospitalized stroke patients have COPD. Presence of COPD is independently associated with higher odds of dying during ischemic stroke hospitalization. Prospective studies are needed to identify any modifiable risk factors contributing to this deleterious relationship.

Acute Stroke Therapy

The presentation of endovascular stroke trials at international stroke conference was a land mark event in acute stroke therapy. This study aims to analyze the rates of utilization of IV r-tPA, with or without mechanical thrombectomy before and after the 2015 International Stroke Conference (ISC) in a large regional tele-stroke network. Methods: A systematic review of prospective telestroke and procedure database was performed for 18 months prior and 18 months post conference. There were three groups included in the analysis. The first group consisted ischemic stroke patients presented within 12 hours of onset including inpatient events, transfers from primary centers and rural clinics. The second group consisted of patients who received IV r-tPA, and the third group consisted of patients who received IV r-tPA and/or underwent mechanical thrombectomy for a demonstrated LVO. Results: A total of 2628 consecutive ischemic stroke events presented within 12 hours of onset were evaluated. In the pre-ISC conference group, there were 1135 ischemic stroke patients. IV r-tPA was given 535 times(47.1%) and mechanical thrombectomy was utilized in addition to IV r-tPA or alone 42 times(3.7%). In the post-ISC conference group, there were 1493 ischemic stroke patients. IV r-tPA was given 642 times(43%) and mechanical thrombectomy was utilized in addition to IV r-tPA or alone 132 times(8.84%). The Chi Square statistical test was performed comparing these groups. When comparing the rate of IV r-tPA usage, there was a significant decrease from the pre-ISC conference group to the post-ISC conference group (P= 0.04). When comparing the rate of mechanical thrombectomy performed, there was a significant increase of greater than double the percentage of thrombectomy procedures performed in the post conference group compared to the preconference group (p< 0.001). Conclusion: There was a significant decrease in IV r-tPA usage but a greater than double the increase in the thrombectomy rate . This may be secondary to increased awareness of benefit of thrombectomy at referral centers. Slightly lower rates of IV r-tPA usage may be secondary to an increase in transfers of patients outside of the 0-4.5 hr window but were deemed candidates for thrombectomy.

Introduction: An overwhelming benefit from endovascular treatment (EVT) of acute ischemic stroke (AIS) has been shown in recent trials, making it the new evidence-based standard of care for ischemic stroke due to anterior circulation large vessel occlusion. We sought to determine usage, safety and efficacy of EVT in patients ≥80 years of age. Methods: Using GWTG stroke registry data from MGH and UAMS, we analyzed 7,505 consecutive stroke admissions from 01/2009 - 06/2016. Univariate analysis was carried out to compare AIS patients < 80 vs. those ≥ 80yr. Results: Of the total 7,505 AIS patients, 3,722 presented within 12 hr of last known well and of these 334 (334/3722, 9%) underwent EVT. The majority of AIS patients undergoing EVT were younger than 80yr of age (264/334, 79%). Of the patients who underwent EVT, younger patients were more often male, Caucasian, and had stroke risk factors of atrial fibrillation, CAD, hypertension and smokers. The two groups were similar in NIHSS, initial clinical presentation, modified pre-stroke Rankin scale of ≤ 3, and initiation of tPA as a drip and ship or stroke center front-door administration. Higher rates of pneumonia were observed in younger patients while rates of sICH were similar. Younger patients were more often discharged to home/inpatient rehabilitation facility. On univariate analysis, in-hospital mortality was significantly higher in patients ≥ 80yr [Unadj. OR 2.50 (1.24, 5.03), p=0.01], however the strength of the association attenuated substantially after adjusting for significant covariates [Adj. OR 2.34 (0.99, 5.47), p=0.05] (Table). Conclusion: Elderly stroke patients are largely excluded from clinical trials and data are limited on the effectiveness of EVT in this cohort. Our results showed that rate of sICH and adjusted in-hospital mortality was not statistically different between those < 80yr vs. ≥ 80yr. Further studies are needed to explore the functional outcome of the elderly stroke patients undergoing EVT.
