Stroke Center Care and Outcome: Results from the CSPPC Stroke Program
The aim of this study was to assess the association between admission to stroke centers for acute ischemic stroke and complications and mortality during hospitalization in a Chinese population by means of an observational study using data from the China Stroke Center Data-Sharing Platform. We compared in-hospital complications and mortality for patients admitted with acute ischemic stroke (N = 13,236) between November 1, 2018 and December 31, 2018 at stroke center (SH) and non-stroke center (CH) hospitals using distance to hospitals as an instrumental variable to adjust for potential prehospital selection bias. The results showed that complication rates during hospitalization among ischemic stroke patients who received thrombolytic therapy (n = 11,203) were lower in the SH group than in the CH group: 11.1% vs 15.7% (absolute difference, − 5.11% [95% CI, − 6.05 to − 3.99%], odds ratio [OR] 0.85 [95% CI, 0.74 to 0.92]). The incidence of intracranial hemorrhage was reduced from 4.2 to 3.2%: SH group vs CH group, 3.2% vs 4.2% (absolute difference, − 1.24% [95% CI, − 1.65 to − 0.82%], OR 0.83 [95% CI, 0.69 to 0.0.98]). Furthermore, the total mortality rate in the SH group was also lower than in the CH group: SH group vs CH group, 2.2% vs 3.0% (absolute difference, − 0.92% [95% CI, − 1.48 to − 0.53%], OR 0.85 [95% CI, 0.73 to 0.96]). The data showed that admission to SH hospitals was associated with a lower risk of treatment complications and death for patients with an acute ischemic stroke receiving thrombolytic therapy.
