Endovascular treatment outcomes using the Stroke Triage Education, Procedure Standardization, and Technology (STEPS-T) program.

ABSTRACT: Background "Door to treatment" time affects outcomes of acute ischemic stroke (AIS) patients undergoing endovascular treatment (EVT). However, the correlation between staff education and accessible technology with stroke outcomes has not been demonstrated. Objective The objective of this paper is to demonstrate the five-year impact of the Stroke Triage Education, Procedure Standardization, and Technology (STEPS-T) program on time-to-treat and clinical outcomes. Methods The study analyzed a prospectively maintained database of AIS patients who benefited from EVT through implementation of STEPS-T. Demographics, clinical characteristics, and modified Rankin Score at three months were analyzed. Thrombolysis in Cerebral Infarction (TICI) scale was used to grade pre- and post-procedure angiographic recanalization. Using electronic hemodynamic recording, stepwise workflow times were collected for door time (TD), entering angiography suite (TA), groin puncture (TG), first DSA (TDSA), microcatheter placement (TM), and final recanalization (TR). Median intervention time (TA to TR) and recanalization time (TG to TR) were compared through Year 1 to Year 5. Results A total of 230 individuals (age 74?±?12, between 30 to 95) were enrolled. Median intervention and recanalization times were significantly reduced, from 121 minutes to 52 minutes and from 83 minutes to 36 minutes respectively from Year 1 to Year 5, ( p?

Project description:Background and purposeEndovascular treatment for acute ischemic stroke consists of various mechanical and pharmacologic modalities used for recanalization of arterial occlusions. We performed this study to determine the relationship among procedure time, recanalization, and clinical outcomes in patients with acute ischemic stroke undergoing endovascular treatment.Materials and methodsWe analyzed data from consecutive patients with acute ischemic stroke who underwent endovascular treatment during a 6-year period. Demographic characteristics, NIHSS score before and 24 hours after the procedure, and discharge mRS score were ascertained. Procedure time was defined by the time interval between microcatheter placement and recanalization or completion of the procedure. We estimated the procedure time after which favorable clinical outcome was unlikely, even after adjustment for age, time from symptom onset, and admission NIHSS scores.ResultsWe analyzed 209 patients undergoing endovascular treatment (mean age, 65 ± 16 years; 109 [52%] men; mean admission/preprocedural NIHSS score, 15.3 ± 6.8). Complete or partial recanalization was observed in 176 (84.2%) patients, while unfavorable outcome (mRS 3-6) was observed in 138 (66%) patients at discharge. In univariate analysis, patients with procedure time ≤30 minutes had lower rates of unfavorable outcome at discharge compared with patients with procedure time ≥30 minutes (52.3% versus 72.2%, P = .0049). In our analysis, the rates of favorable outcomes in endovascularly treated patients after 60 minutes were lower than rates observed with placebo treatment in the Prourokinase for Acute Ischemic Stroke Trial. In logistic regression analysis, unfavorable outcome was positively associated with age (P = .0012), admission NIHSS strata (P = .0017), and longer procedure times (P = .0379).ConclusionsProcedure time in patients with acute ischemic stroke appears to be a critical determinant of outcomes following endovascular treatment. This highlights the need for procedure time guidelines for patients being considered for endovascular treatment in acute ischemic stroke.

Project description:BACKGROUND AND PURPOSE:Despite strong evidence for endovascular therapy in adults with acute arterial ischemic stroke, limited data exist in children. We aimed to describe endovascular therapy utilization and explore outcomes in a national sample of pediatric arterial ischemic stroke. METHODS:We queried the 2012 Kids' Inpatient Database for children aged greater than 28 days to 20 years with the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes for arterial ischemic stroke and evaluated groups based on the procedure code for endovascular therapy. Poor outcome was defined as need for tracheostomy or gastrostomy, discharge to rehabilitation facility, or death. Logistic regression evaluated the association between endovascular therapy and poor outcome, adjusted for age, disease severity (hemiplegia, critical care interventions, neurosurgical interventions), and comorbidities. RESULTS:We identified 3184 pediatric discharges with a diagnosis code for arterial ischemic stroke. Thirty-eight (1%) had an endovascular therapy procedure code. Endovascular therapy patients were older (10.2 versus 4.5 years, P < 0.001) and more likely to have hemiplegia/paresis (relative risk [RR] 3.8, 95% confidence interval [CI] 2.0-7.4), aphasia (RR 5.3, 95% CI 2.8-10.1), and facial droop (RR 4.0, 95% CI 1.9-8.7). Endovascular therapy was not associated with critical care and neurosurgical interventions or intracranial hemorrhage. Length of hospitalization, mortality, and discharge disposition were similar between groups. In a multivariable model, endovascular therapy was not associated with poor outcome (adjusted odds ratio 1.7, 95%, CI 0.7-4.1). CONCLUSIONS:In a national sample of children with a diagnosis of arterial ischemic stroke, endovascular therapy was infrequently utilized. Patients with a procedure code for endovascular therapy had significant stroke-related deficits, but outcomes were similar to those in children who did not receive endovascular therapy. Our data, in conjunction with evidence of benefit in adults, support consideration of endovascular therapy for select children with acute stroke.

Project description:Background The long-term outcomes of acute large vessel occlusion (LVO) in anterior circulation treated by endovascular treatment (EVT) remains to be determined. The aim of this study was to assess the 5-year outcomes of patients with LVO who underwent EVT. Methods This study was an observational, nationwide registry of consecutive patients with acute LVO who received EVT in 28 comprehensive stroke centers in China. The primary outcome was the proportion of favorable outcome [modified Rankin Scale score (mRS) 0–2] at 5 years. Secondary outcomes included proportions of patients with excellent outcome (mRS 0–1), all-cause mortality and risk of stroke recurrence at 5 years. Results A total of 807 patients were included into the study and had 90-day follow-up data, 657 patients had 5-year follow-up data. At 90 days, 218 patients (27.0%) had an excellent outcome, 349 patients (43.2%) had a favorable functional outcome. 199 patients (24.7%) died. At 5 years, 190 patients (28.9%) had an excellent outcome, 261 patients (39.7%) had a favorable functional outcome, 317 patients (48.2%) died and 129 (28.2%) had stroke recurrence. Because of missing 5-year follow-up data, among available 269 patients who achieved functional independence at 90 days, 208 (77.3%) maintained favorable outcome, 19 (7.1%) had disability (mRS 3–5) and 42 (15.6%) died at 5 years. Furthermore, among available 189 patients with mRS 3–5 at 90 days, 53 (28.0%) patients achieved favorable functional outcome, 60 (31.7%) patients maintained unfavorable functional outcome and 76 (40.2%) patients died within 5 years. Multivariate analyses identified that younger age [odds ratio (OR): 0.96; 95% CI, 0.93–0.99; P = 0.009], lower mRS at 90 days (OR: 0.15; 95% CI, 0.10–0.23; P < 0.001) and absence of stroke recurrence (OR: 0.001; 95% CI, 0.000–0.006; P < 0.001) were significantly associated with favorable outcome at 5 years. Advanced age (OR: 1.06, 95% CI, 1.04–1.08; P < 0.001), higher mRS at 90 days (OR: 0.84; 95% CI, 0.73–0.98; P = 0.021) and atrial fibrillation (OR: 1.63; 95% CI, 1.02–2.60; P = 0.04) were independent factors for stroke recurrence. Conclusion Our results indicated that the beneficial effect of EVT in patients with acute LVO can be sustained during the course of at least 5 years. Reducing the risk of stroke recurrence by anticoagulation for atrial fibrillation may be a crucial strategy to improve long-term outcome.
