    In China and other parts of the world, hospital personnel adherence to evidence-based stroke care is limited.To determine whether a multifaceted quality improvement intervention can improve hospital personnel adherence to evidence-based performance measures in patients with acute ischemic stroke (AIS) in China.A multicenter, cluster-randomized clinical trial among 40 public hospitals in China that enrolled 4800 patients hospitalized with AIS from August 10, 2014, through June 20, 2015, with 12-month follow-up through July 30, 2016.Twenty hospitals received a multifaceted quality improvement intervention (intervention group; 2400 patients), including a clinical pathway, care protocols, quality coordinator oversight, and performance measure monitoring and feedback. Twenty hospitals participated in the stroke registry with usual care (control group; 2400 patients).The primary outcome was hospital personnel adherence to 9 AIS performance measures, with co-primary outcomes of a composite of percentage of performance measures adhered to, and as all-or-none. Secondary outcomes included in-hospital mortality and long-term outcomes (a new vascular event, disability [modified Rankin Scale score, 3-5], and all-cause mortality) at 3, 6, and 12 months.Among 4800 patients with AIS enrolled from 40 hospitals and randomized (mean age, 65 years; women, 1757 [36.6%]), 3980 patients (82.9%) completed the 12-month follow-up of the trial. Patients in intervention group were more likely to receive performance measures than those in the control groups (composite measure, 88.2% vs 84.8%, respectively; absolute difference, 3.54% [95% CI, 0.68% to 6.40%], P = .02). The all-or-none measure did not significantly differ between the intervention and control groups (53.8% vs 47.8%, respectively; absolute difference, 6.69% [95% CI, -0.41% to 13.79%], P = .06). New clinical vascular events were significantly reduced in the intervention group compared with the control group at 3 months (3.9% vs 5.3%, respectively; difference, -2.03% [95% CI, -3.51% to -0.55%]; P = .007), 6 months (6.3% vs 7.8%, respectively; difference, -2.18% [95% CI, -4.0% to -0.35%]; P = .02) and 12 months (9.1% vs 11.8%, respectively; difference, -3.13% [95% CI, -5.28% to -0.97%]; P = .005).Among 40 hospitals in China, a multifaceted quality improvement intervention compared with usual care resulted in a statistically significant but small improvement in hospital personnel adherence to evidence-based performance measures in patients with acute ischemic stroke when assessed as a composite measure, but not as an all-or-none measure. Further research is needed to understand the generalizability of these findings.ClinicalTrials.gov Identifier: NCT02212912.

    Relationship between hospital performance measures and outcomes in patients with acute ischaemic stroke: a prospective cohort study.
    (BMJ open, 2018-08) Zhang, Xinmiao; Li, Zixiao; Zhao, Xingquan; Xian, Ying; Liu, Liping; Wang, Chunxue; Wang, Chunjuan; Li, Hao; Prvu Bettger, Janet; Yang, Qing; Wang, David; Jiang, Yong; Bao, Xiaolei; Yang, Xiaomeng; Wang, Yilong; Wang, Yongjun
    OBJECTIVE:Evidence-based performance measures have been increasingly used to evaluate hospital quality of stroke care, but their impact on stroke outcomes has not been verified. We aimed to evaluate the correlations between hospital performance measures and outcomes among patients with acute ischaemic stroke in a Chinese population. METHODS:Data were derived from a prospective cohort, which included 120 hospitals participating in the China National Stroke Registry between September 2007 and August 2008. Adherence to nine evidence-based performance measures was examined, and the composite score of hospital performance measures was calculated. The primary stroke outcomes were hospital-level, 30-day and 1-year risk-standardised mortality (RSM). Associations of individual performance measures and composite score with stroke outcomes were assessed using Spearman correlation coefficients. RESULTS:One hundred and twenty hospitals that recruited 12 027 patients with ischaemic stroke were included in our analysis. Among 12 027 patients, 61.59% were men, and the median age was 67 years. The overall composite score of performance measures was 63.3%. The correlation coefficients between individual performance measures ranged widely from 0.01 to 0.66. No association was observed between the composite score and 30-day RSM. The composite score was modestly associated with 1-year RSM (Spearman correlation coefficient, 0.34; p<0.05). The composite score explained only 2.53% and 10.18% of hospital-level variation in 30-day and 1-year RSM for patients with acute stroke. CONCLUSIONS:Adherence to evidence-based performance measures for acute ischaemic stroke was suboptimal in China. There were various correlations among hospital individual performance measures. The hospital performance measures had no correlations with 30-day RSM rate and modest correlations with 1-year RSM rate.

    Treatment Effect of Clopidogrel Plus Aspirin Within 12 Hours of Acute Minor Stroke or Transient Ischemic Attack.
    (Journal of the American Heart Association, 2016-03-21) Li, Zixiao; Wang, Yilong; Zhao, Xingquan; Liu, Liping; Wang, David; Wang, Chunxue; Meng, Xia; Li, Hao; Pan, Yuesong; Wang, Xianwei; Wang, Chunjuan; Yang, Xiaomeng; Zhang, Changqing; Jing, Jing; Xian, Ying; Johnston, S Claiborne; Wang, Yongjun; CHANCE Investigators
    BACKGROUND:The aim of this study was to analyze the benefits and safety associated with the combination therapy of clopidogrel and aspirin among minor stroke or transient ischemic attack patients treated within 12 hours. METHODS AND RESULTS:This was a subanalysis of the CHANCE (Clopidogrel in High-Risk Patients with Acute Nondisabling Cerebrovascular Events) trial, mainly limited to the prespecified group of patients randomized within 12 hours to either the combination of clopidogrel plus aspirin or aspirin alone. The primary outcome was ischemic stroke during 90-day follow-up. Recurrent ischemic stroke and progressive ischemic stroke were analyzed. Multivariable Cox modeling showed that randomization within 12 hours was an independent predictor of ischemic stroke events (hazard ratio [95% CI] 1.25 [1.04-1.49], P=0.02). Among 2573 patients randomized within 12 hours, 282 (10.96%) patients had ischemic stroke events. Among them, 158 (12.34%) of 1280 patients taking aspirin experienced ischemic stroke compared with 124 (9.59%) of 1293 patients taking clopidogrel-aspirin (P=0.02). The dual antiplatelet was more effective than aspirin alone in reducing the risk of recurrent ischemic stroke (6.57% versus 8.91%, P=0.03) but not progressive ischemic stroke (3.02% versus 3.43%, P=0.28). There was no significant difference in hemorrhagic events (P=0.39). CONCLUSIONS:Among patients treated within 12 hours, the combination of clopidogrel and aspirin was more effective than aspirin alone in reducing the risk of recurrent ischemic stroke during the 90-day follow-up and did not increase the hemorrhagic risk.
