Background And Purpose

Method

We applied the THRIVE score in 11,064 patients with acute ischemic stroke who were entered into the China National Stroke Registry. We applied the THRIVE score and examined its performance on mortality and poor functional outcome (modified Rankin Scale score between 3 and 6). Model discrimination was measured by c-statistic. Calibration was assessed by comparing predicted and observed probability of poor outcome or mortality by using Pearson correlation coefficient.

Conclusion

The THRIVE score is a reliable tool to predict the mortality and to fairly predict the functional outcome at discharge, and at 3, 6, and 12 months in Chinese patients after acute ischemic stroke.

Main results

Among the 11,064 patients with ischemic stroke, the mortality rates at discharge, and at 3, 6, and 12 months were 3.6%, 7.9%, 10.5%, and 12.7%, respectively; the corresponding c-statistics were .83(95% confidence interval [CI], .80-.86), .79(95% CI, .77-.81), .80(95% CI, .78-.81), and .79(95% CI, .78-.80), respectively. For the poor functional outcome at discharge, and at 3, 6, and 12 months, the c-statistics were .74(95% CI, .73-.75), .76(95% CI, .75-.77), .76(95% CI, .75-.77), and .77(95% CI, .76-.78), respectively. The observed and expected probability of poor functional outcome and mortality based on the THRIVE score correlated (Pearson correlation coefficient ranged from .90 to .99) highly.
