Introduction: IV tPA delivery is challenging and use varies widely. We analyzed differences in patient and hospital characteristics at the hospital level in the Get with the Guidelines (GWTG) - Stroke database. Methods: We analyzed data on 73574 patients from 2003-2011 at 1231 hospitals with ≥10 tPA-eligible ischemic stroke (AIS) patients arriving < 2 hr of onset, divided into quartiles of rates of tPA delivered within 3 hrs of onset. Median percentages are reported, and temporal trends were calculated using absolute changes from 2010-2011 vs. 2003-2005. Results: Patients at hospitals with lower rates of tPA treatment within 3 hrs were older, more frequently white, used EMS less often, had lower NIHSS values with very high rates of missing NIHSSS, and greater door to imaging times as compared to better performing hospitals. Hospitals with lower rates of tPA treatment were smaller and more rural, had fewer ICU beds, and were less often teaching or primary stroke centers (Table 1). IV tPA use increased across all types of hospitals from 2003-2011, but increased to a greater degree in non-primary stroke centers and those in the South and West (Table 2). Teaching status, bed size and other measured variables were not different. Conclusion: Significant increases in IV tPA treatment among patients arriving < 2hr have occurred over the past decade, and rates of increase vary by hospital characteristics. The profile of tPA treated eligible patients also changes across the range of hospital tPA use rates, with highest performing sites reporting NIHSS in >90% of tPA patients, and treating greater numbers of patients who are non-white or with more severe strokes. Low performing sites may benefit from greater focus on NIHSS assessment and timeliness of care. .

Background: Although designated stroke centers (DSCs) improve the quality of care and clinical outcomes for ischemic stroke patients, less is known about the benefits of DSCs for patients with intracerebral hemorrhage (ICH) and subarachnoid hemorrhage (SAH). Hypothesis: Compared to non-DSCs, hospitals with the DSC status have lower in-hospital mortality rates for hemorrhagic stroke patients. We believed these effects would sustain over a period of time after adjusting for hospital-level characteristics, including hospital size, urban location, and teaching status. Methods and Results: We evaluated ICH (International Classification of Diseases, Ninth Revision; ICD-9: 431) and SAH (ICD-9: 430) hospitalizations documented in the 2008-2012 New York State Department of Health Statewide Planning and Research Cooperative System inpatient sample database. Generalized estimating equation logistic regression was used to evaluate the association between DSC status and in-hospital mortality. We calculated ORs and 95% CIs adjusted for clustering of patients within facilities, other hospital characteristics, and individual level characteristics. Planned secondary analyses explored other hospital characteristics associated with in-hospital mortality. In 6,352 ICH and 3,369 SAH patients in the study sample, in-hospital mortality was higher among those with ICH compared to SAH (23.7 vs. 18.5%). Unadjusted analyses revealed that DSC status was related with reduced mortality for both ICH (OR 0.7, 95% CI 0.5-0.8) and SAH patients (OR 0.4, 95% CI 0.3-0.7). DSC remained a significant predictor of lower in-hospital mortality for SAH patients (OR 0.6, 95% CI 0.3-0.9) but not for ICH patients (OR 0.8, 95% CI 0.6-1.0) after adjusting for patient demographic characteristics, comorbidities, hospital size, teaching status and location. Conclusions: Admission to a DSC was independently associated with reduced in-hospital mortality for SAH patients but not for those with ICH. Other patient and hospital characteristics may explain the benefits of DSC status on outcomes after ICH. For conditions with clear treatments such as ischemic stroke and SAH, being treated in a DSC improves outcomes, but this trend was not observed in those with strokes, in those who did not have clear treatment guidelines. Identifying hospital-level factors associated with ICH and SAH represents a means to identify and improve gaps in stroke systems of care.

Abstract Background Decreasing inappropriate urine cultures in hospitalized patients has been a target of diagnostic stewardship to improve infection surveillance and antimicrobial use. The impact of such efforts has been largely unstudied. This study assessed temporal trends in urine culture rates in a cohort of acute care hospitals (ACHs) between 2012 and 2017. Hospital Level Variation in Admission Urine Culture Rates Hospital Level Variation in Post-admission Urine Culture Rates Methods We used microbiology data from ACHs participating in the Premier Healthcare Database and Cerner Health Facts to measure monthly urine culture rates. All cultures from the urinary tract collected on or before day 3 were defined as admission cultures (AC) and those collected on day 4 or later as post-admission cultures (PAC). Temporal trends in AC and PAC rates were estimated using general estimating equation models adjusting for hospital-level clustering, hospital size, teaching status, urban/rural designation, discharge month, and region. Results During the study period, ACHs had 20.8 million discharges and performed 4,946,717 urine cultures, of which 21% were PAC. In 2012 and 2017, the unadjusted AC rates were 18.7 and 18.4 per 100 discharges; the unadjusted PAC rates were 11.5 and 8.5 per 1,000 patient days (PD) respectively. The median annual hospital-level AC rate was 17.2 with inter-hospital variation ranging from 12.7 (quartile 1) to 24.1 (quartile 3) per 100 discharges, Figure 1. Similarly, the PAC rates varied among the ACHs with a median of 7.1 and inter-hospital variation ranging from 4.6 (quartile 1) to 10.5 (quartile 3) per 1,000 PDs, Figure 2. In multivariable analysis, no temporal trends in AC rates were detected (rate ratio (RR) 1.01; 95% confidence interval (CI): 0.99–1.02). However, PAC rates decreased 6.3% annually (RR 0.937; 95% CI: 0.93–0.95). Factors significantly associated (p&lt; 0.02) with PAC rates were discharge month, teaching status, bed size, and region. For AC, significant associations (p&lt; 0.0001) were discharge month and region. Conclusion Between 2012 and 2017, the rate of AC remained unchanged, but PAC rates decreased significantly. Factors driving this trend are unknown, but potential explanations include changes in culturing practices and/or decreases in hospital-onset urinary tract infections. Understanding factors related to the decrease and the impact on patient outcomes warrants further study. Disclosures All Authors: No reported disclosures

Introduction: A significant proportion of acute ischemic strokes occur while patients are hospitalized for other reasons. Limited data exist on the utilization of intravenous alteplase (IV tPA) for in-hospital stroke, particularly in the endovascular era. We compared temporal trends of IV tPA use, patient characteristics, process measures of quality, and outcomes for in-hospital versus community onset strokes in a national registry. Methods: We performed a retrospective cohort study of Get With The Guidelines-Stroke (GTWG-Stroke) from January 2008 to June 2018 from 2,333 participating sites that included 2,428,178 patients with acute ischemic stroke. In-hospital onset was reported in 67,493 patients. We examined the association between stroke onset location, patient characteristics, comorbidities, treatment with IV tPA and unadjusted and adjusted functional outcomes (Table, standardized differences >10% for significance). Results: Of 67,493 patients with in-hospital onset stroke, 11,123 received IV tPA. The rate of IV tPA administration steadily increased, from 9.5% in 2008 to 20.7% in 2017 (p<0.001). Compared with patients with community-onset strokes who were treated with IV tPA, patients with in-hospital onset stroke had longer times to cranial imaging and administration of IV tPA. Patients with in-hospital onset stroke were less likely to be treated within 60 minutes of recognition, and at discharge, ambulate independently or go directly home. They were more likely to die or be discharged to hospice after adjusting for patient and hospital characteristics. Conclusions: In this national cohort, in-hospital onset strokes are increasingly treated with intravenous tPA in a period that spans the endovascular era. Compared with community-onset stroke, patients with in-hospital onset stroke had longer intervals to thrombolysis and worse outcomes. These data highlight opportunities to improve inpatient systems of stroke care further.

Background: Avoidance of readmission is linked to improved quality of care, reduction in cost, and is a desirable patient-centered outcome. Nationally representative readmission metrics for patients with acute ischemic stroke treated with intravenous thrombolytic treatment (IV-tPA) are unavailable to date. Such estimates are necessary for benchmarking performance. Objectives: To identify US nationwide estimates and a temporal trend for 30-day hospital readmissions. Methods: We identified the cohort by year-wise analysis of the Nationwide Readmissions Database between January 1, 2010, and September 30, 2015. The database represents 50% of all US hospitalizations from 22 geographically dispersed states. Participants were adult (=>18 years) patients with a primary discharge diagnosis of acute ischemic (ICD-9-CM 433.x1 and 434.x1) who were treated with thrombolytic therapy (ICD-9-CM 9910). Readmission was defined as any admission within 30 days of index hospitalization discharge. Results: Based on study criteria, 57,676 eligible patients were included (mean [SE] age, 68.7 ± 14.4 years; 48.7% were women). Thirty-day readmission rate for acute ischemic stroke patients treated with IV-tPA was 11.17 % (95%CI, 10.92 %-11.43%). On average, there was a 4.4% annual decline in readmission between 2010 and 2014, which was statistically significant for the period of investigation (odds ratio, 0.95; 95%CI, 0.94-0.97). Age ≥ 65 years (OR 1.16 P <.0001), medical history of congestive heart failure (OR 1.11 P = 0.0056), chronic lung disease (OR 1.11 P = 0.0034) and renal failure (OR 1.35 P = <.0001) were independent predictors of readmission within 30 days. Conclusion: Nationally representative readmission metrics can be used to benchmark hospitals’ performance, and a temporal trend of 4.4 % may be used to evaluate the effectiveness of readmission reduction strategies.

Introduction: Utilization of IV tPA is challenging for many hospitals. Using data from the national Get With The Guidelines-Stroke program, we analyzed changes over time in the characteristics of the hospitals that treated patients with tPA. Methods: We analyzed patient-level data from 2003-2011 at 1600 GWTG hospitals that joined the program at any time during the study period and admitted any acute ischemic stroke (AIS) patients arriving ≤ 2 hr of onset and eligible for tPA. Descriptive trends by time were analyzed by chi-square or Wilcoxon test for continuous data. Results: IV tPA was given within 3 hr at 1394 sites to 50,798/ 75,115 (67.6%) eligible AIS patients arriving ≤ 2 hr; 206 (14.8%) sites had a least one eligible patients but no tPA use. IV tPA treatment rates varied substantially across hospitals (median 61.2%, range 0-100%), with > 200 hospitals providing tPA < 10% of the time (Figure). Over time, more patients and a larger proportion of patients were treated at smaller (median bed size 407 vs. 372, p< 0.001), non-academic, Southern hospitals, and those with lower annualized average ischemic stroke volumes (252.4 vs. 235.2, p< 0.001) (Table). While more than half of all tPA patients were treated at Primary Stroke Centers, this proportion did not change over time. The proportion of patients treated at high volume tPA treatment sites (average > 20/year) increased over time (31.9 vs. 34.5, p< 0.007). Conclusion: Over the past decade, while primary stroke centers still account for more than half of all treatments, tPA has been increasingly delivered in smaller, non-academic hospitals. These data support the continued emphasis on stroke team building and systems of care at US hospitals.

AbstractBackground:Death after acute stroke often occurs after forgoing life-sustaining interventions. We sought to determine the patient and hospital characteristics associated with an early decision to transition to comfort measures only (CMO) after ischemic stroke (IS), intracerebral hemorrhage (ICH), and subarachnoid hemorrhage (SAH) in the Get With The Guidelines–Stroke registry.Methods:We identified patients with IS, ICH, or SAH between November 2009 and September 2013 who met study criteria. Early CMO was defined as the withdrawal of life-sustaining treatments and interventions by hospital day 0 or 1. Using multivariable logistic regression, we identified patient and hospital factors associated with an early (by hospital day 0 or 1) CMO order.Results:Among 963,525 patients from 1,675 hospitals, 54,794 (5.6%) had an early CMO order (IS: 3.0%; ICH: 19.4%; SAH: 13.1%). Early CMO use varied widely by hospital (range 0.6%–37.6% overall) and declined over time (from 6.1% in 2009 to 5.4% in 2013; p < 0.001). In multivariable analysis, older age, female sex, white race, Medicaid and self-pay/no insurance, arrival by ambulance, arrival off-hours, baseline nonambulatory status, and stroke type were independently associated with early CMO use (vs no early CMO). The correlation between hospital-level risk-adjusted mortality and the use of early CMO was stronger for SAH (r = 0.52) and ICH (r = 0.50) than AIS (r = 0.15) patients.Conclusions:Early CMO was utilized in about 5% of stroke patients, being more common in ICH and SAH than IS. Early CMO use varies widely between hospitals and is influenced by patient and hospital characteristics.

Introduction: Two RCTs conducted from 2010-2018 showed benefit in ischemic stroke (IS) of IV tPA >4.5 h from last known well (LKW) using advanced imaging selection. Many subjects were wakeup strokes treated < 4.5 h of symptom discovery (SxD). We assessed the frequency of IV tPA > 4.5 h in the national GWTG-Stroke clinical registry during the same period as the RCTs were performed. Methods: We analyzed all IS hospitalizations between 1/1/09 - 10/1/18 at fully participating GWTG-Stroke sites to identify 219,565 patients at 1919 sites who received IV tPA (no thrombectomy) and had valid LKW, SxD and treatment times recorded. Table shows significant covariates (standardized differences >10%) Results: Treatment beyond 4.5 h from LKW was rare, occurring in 2.19% (n=4798) of all tPA cases, and 50% of those treated were still within 4.5 h from SxD. The distribution of time to treatment in minutes was similar when stroke onset was defined by LKW compared to SxD (median (IQR) 134 (100-174) vs. 125 (94-163)) (Fig). The use of IV tPA at >4.5 h from LKW as a proportion of all tPA cases treated varied substantially across sites (median (IQR) 1.7% (0-3.1%)) but fewer than ~10% of sites had more than 5% of their tPA use occurring beyond 4.5 h. Compared to < 4.5 h, patients treated >4.5 h differed in age, AF, arrival mode/time, stroke severity and hospital region (Table). Conclusions: During the past decade and prior to published RCT evidence that extended window IV tPA was effective, US sites in GWTG-Stroke rarely treated patients beyond the guideline-approved window of 4.5 h. It will be important to monitor adoption of extended window thrombolysis in the US, and determine if additional RCT data are required to change practice.

National guidelines recommend dysphagia screening (DS) before any oral intake in hospitalized stroke patients to reduce the risk of hospital-acquired pneumonia (HAP). We examined the relationship between DS and HAP in acute ischemic stroke patients in the Get With the Guidelines-Stroke (GWTG-S) program. Methods: Data from 1251 GWTG-S hospitals from 04/01/2003 to 03/01/2009 were analyzed. GWTG-S defines HAP as a clinical diagnosis of pneumonia requiring antibiotics. Use of a bedside, evidence-based swallow screen prior to any oral intake qualified as a DS. Univariate analyses (chi-square for categorical variables or Wilcoxon for continuous variables) and multivariate logistic regression analyses were performed to examine the relationship between DS and HAP, adjusting for patient and hospital characteristics Results: Among 365,726 ischemic stroke patients, 213097 (59.83%) underwent DS, and 25,166 (6.88%) developed HAP. When compared to patients without pneumonia ( Table 1 ), patients with HAP were older and more frequently had CAD/MI, diabetes, prior stroke/TIA, dyslipidemia, atrial fibrillation. They, underwent DS less often, and had increased length of stay, morbidity and in-hospital mortality. Among the subgroup who had NIHSS recorded (n=160,837, 44%), HAP patients had higher median NIHSS (13 vs. 5). Among patients with NIHSS<2, 3.3% developed HAP. In multivariate analysis, factors independently associated with a lower risk of HAP were DS (OR 0.86 [0.83-0.90]), female (OR 0.83 [0.81-0.85]), dyslipidemia (OR 0.84 [0.82-0.86]), and hypertension (OR 0.96 [0.94-0.98]). Discussion: Our data suggests that dysphagia screening is associated with a lower likelihood of HAP, but screening rates remain low. Strategies that increase the rate of dysphagia screening among all stroke patients, even those with mild strokes, should be more broadly implemented. Prospective validation of these findings is warranted. Table 1.
