Background And Purpose
Stroke represents a significant burden on the health care system of China. The Chinese Stroke Center Alliance was launched in 2015 to monitor and improve care quality and outcomes for patients with acute stroke and transient ischemic attack (TIA). To evaluate the clinical characteristics, management, and in-hospital clinical outcomes and complications among patients with stroke or TIA in China.
Method
This quality improvement study assessed stroke or TIA admissions to 1476 participating hospitals in the Chinese Stroke Center Alliance between August 1, 2015, and July 31, 2019. Eleven guideline-based admission or discharge management measures and 2 summary measures: an all-or-none binary outcome and a composite score (range, 0 [nonadherence] to 1 [perfect adherence]) for adherence to evidence-based stroke and TIA care and in-hospital clinical outcomes, including death or discharge against medical advice (DAMA), major adverse cardiovascular events (MACEs), including ischemic stroke, hemorrhagic stroke, TIA, or myocardial infarction; and in-hospital complications.
Conclusion
In this quality improvement study, performance measure adherence and poor outcomes and complications varied by cerebrovascular event type; although there were substantial improvements over time, these results suggest that support for the use of evidence-based practices is needed.
Main results
Of 1 006798 patients with stroke or TIA (mean [SD] age, 65.7 [12.2] years; 383500 [38.1%] female), 838 229 (83.3%) had an ischemic stroke, 64929 (6.4%) had TIA, 85 705 (8.5%) had intracerebral hemorrhage (ICH), and 11 241 (1.1%) had subarachnoid hemorrhage (SAH). Management measures varied by cerebrovascular event type, with the mean (SD) composite score ranging from 0.57 (0.31) in SAH to 0.83 (0.24) in TIA. Poor outcomes and complicationswere highest among patients with SAH (21.9%; 95% CI, 21.0%-22.8% in-hospital death or DAMA; 9.6%; 95% CI, 9.1%-10.2%MACEs; and 31.4%; 95% CI, 30.6%-32.3% in-hospital complications) and patients with ICH (17.2%; 95% CI, 16.9%-17.5% in-hospital death or DAMA; 9.3%; 95% CI, 9.1%-9.5%MACEs; and 31.3%; 95% CI, 31.0%-31.6% in-hospital complications), followed by patients with ischemic stroke (6.1%; 95% CI, 6.0%-6.1% in-hospital death or DAMA; 6.3%; 95% CI, 6.3%-6.4%MACEs; and 12.8%; 95% CI, 12.7%-12.9% in-hospital complications), and lowest in patients with TIA (5.0%; 95% CI, 4.8%-5.2% in-hospital death or DAMA; 2.4%; 95% CI, 2.3%-2.5%MACEs; and 0.8%; 95% CI, 0.7%0.8%in-hospital complications). Temporal improvements in management measures were observed from 2015 to 2019, especially in administration of intravenous recombinant tissue plasminogen activator (+60.3% relatively; 95% CI, 52.9%-70.5%), dysphagia screening (+14.7% relatively; 95% CI, 14.0%-15.6%), and use of anticoagulants for atrial fibrillation (+31.4% relatively; 95% CI, 25.7%-37.3%). Temporal improvements in in-hospital death or DAMA (−9.7% relatively; 95% CI, −9.6% to −8.5%) and complications (−27.1% relatively; 95% CI, −28.6%to −25.3) were also observed.
