Comparison of Acute Ischemic Stroke Care and Outcomes Between Comprehensive Stroke Centers and Primary Stroke Centers in the United States.

ABSTRACT: BACKGROUND:To improve stroke care, the Brain Attack Coalition recommended establishing primary stroke center (PSC) and comprehensive stroke center (CSC) certification. This study aimed to compare ischemic stroke care and in-hospital outcomes between CSCs and PSCs. METHODS AND RESULTS:We analyzed patients with acute ischemic stroke who were hospitalized at stroke centers participating in Get With The Guidelines-Stroke from 2013 to 2015. Multivariable logistic regression models were generated to examine the association between stroke center certification (CSC versus PSC) and performances and outcomes. This study included 722?941 patients who were admitted to 134 CSCs and 1047 PSCs. Both CSCs and PSCs had good conformity to 7 performance measures and the summary defect-free care measure. Among emergency department admissions, CSCs had higher intravenous tPA (tissue-type plasminogen activator) and endovascular thrombectomy rates than PSCs (14.3% versus 10.3%, 4.1% versus 1.0%, respectively). Door to intravenous tPA time was shorter at CSCs (median, 52 versus 61 minutes; adjusted risk ratio, 0.92; 95% confidence interval, 0.89-0.95). More patients at CSCs had door to intravenous tPA time ?60 minutes (79.7% versus 65.1%; adjusted odds ratio, 1.48; 95% confidence interval, 1.25-1.75). For transferred patients, CSCs and PSCs had comparable overall performance in defect-free care, except higher endovascular thrombectomy therapy rates. The overall in-hospital mortality was higher at CSCs in both emergency department admissions (4.6% versus 3.8%; adjusted odds ratio, 1.14; 95% confidence interval, 1.01-1.29) and transferred patients (7.7% versus 6.8%; adjusted odds ratio, 1.17; 95% confidence interval, 1.05-1.32). In-hospital outcomes were comparable between CSCs and PSCs in patients who received intravenous tPA or endovascular thrombectomy. CONCLUSIONS:CSCs and PSCs achieved similar overall care quality for patients with acute ischemic stroke. CSCs exceeded PSCs in timely acute reperfusion therapy for emergency department admissions, whereas PSCs had lower risk-adjusted in-hospital mortality. This information may be important for acute stroke triage and targeted quality improvement.

Project description:We sought to analyze the impact of socioeconomic status (SES) on in-hospital outcomes, cost of hospitalization, and resource use after acute ischemic stroke.We used the 2003-2011 Nationwide Inpatient Sample database for this analysis. All admissions with a principal diagnosis of acute ischemic stroke were identified by using International Classification of Diseases, Ninth Revision codes. SES was assessed by using median household income of the residential ZIP code for each patient. Quartile 1 and quartile 4 reflect the lowest-income and highest-income SES quartile, respectively. During a 9-year period, 775,905 discharges with acute ischemic stroke were analyzed. There was a progressive increase in the incidence of reperfusion on the first admission day across the SES quartiles (P-trend<0.001). In addition, we observed a significant reduction in discharge to nursing facility, across the SES quartiles (P-trend<0.001). Although we did not observe a significant difference in in-hospital mortality across the SES quartiles in the overall cohort (P-trend=0.22), there was a significant trend toward reduced in-hospital mortality across the SES quartiles in younger patients (<75 years) (P-trend<0.001). The mean length of stay in the lowest-income quartile was 5.75 days, which was significantly higher compared with other SES quartiles. Furthermore, the mean adjusted cost of hospitalization among quartiles 2, 3, and 4, compared with quartile 1, was significantly higher by $621, $1238, and $2577, respectively. Compared with the lowest-income quartile, there was a significantly higher use of echocardiography, invasive angiography, and operative procedures, including carotid endarterectomy, in the highest-income quartile.Patients from lower-income quartiles had decreased reperfusion on the first admission day, compared with patients from higher-income quartiles. The cost of hospitalization of patients from higher-income quartiles was significantly higher than that of patients from lowest-income quartiles, despite longer hospital stays in the latter group. This might be partially attributable to a lower use of key procedures among patients from lowest-income quartile.

Project description:BackgroundStudies have shown worse outcomes in patients with comorbid ischemic stroke (IS) and coronavirus disease 2019 (COVID-19), but have had small sample sizes.MethodsWe retrospectively identified patients in the Vizient Clinical Data Base® with IS as a discharge diagnosis. The study outcomes were in-hospital death and favorable discharge (home or acute rehabilitation). In the primary analysis, we compared IS patients with laboratory-confirmed COVID-19 (IS-COVID) discharged April 1-July 31, 2020 to pre-COVID IS patients discharged in 2019 (IS controls). In a secondary analysis, we compared a matched cohort of IS-COVID patients to patients within the IS controls who had pneumonia (IS-PNA), created with inverse-probability-weighting (IPW).ResultsIn the primary analysis, we included 166,586 IS controls and 2086 IS-COVID from 312 hospitals in 46 states. Compared to IS controls, IS-COVID were less likely to have hypertension, dyslipidemia, or be smokers, but more likely to be male, younger, have diabetes, obesity, acute renal failure, acute coronary syndrome, venous thromboembolism, intubation, and comorbid intracerebral or subarachnoid hemorrhage (all p<0.05). Black and Hispanic patients accounted for 21.7% and 7.4% of IS controls, respectively, but 33.7% and 18.5% of IS-COVID (p<0.001). IS-COVID, versus IS controls, were less likely to receive alteplase (1.8% vs 5.6%, p<0.001), mechanical thrombectomy (4.4% vs. 6.7%, p<0.001), to have favorable discharge (33.9% vs. 66.4%, p<0.001), but more likely to die (30.4% vs. 6.5%, p<0.001). In the matched cohort of patients with IS-COVID and IS-PNA, IS-COVID had a higher risk of death (IPW-weighted OR 1.56, 95% CI 1.33-1.82) and lower odds of favorable discharge (IPW-weighted OR 0.63, 95% CI 0.54-0.73).ConclusionsIschemic stroke patients with COVID-19 are more likely to be male, younger, and Black or Hispanic, with significant increases in morbidity and mortality compared to both ischemic stroke controls from 2019 and to patients with ischemic stroke and pneumonia.
