Abstract
AIMS: Little is known about the performance of the maximally treated intracerebral hemorrhage (max-ICH) score in predicting unfavorable long-term functional outcome and death in patients with intracerebral hemorrhage (ICH) in China. We aimed to validate the performance of the max-ICH score and compared it with other recognized scores. METHODS: We derived data from the China National Stroke Registry (CNSR). Receiver-operating characteristic (ROC) analysis and Hosmer-Lemeshow test were used to measure the score performance. We compared the performance of max-ICH score with six recognized models, including the ICH score, ICH functional outcome score (ICH-FOS), Essen-ICH score, modified intracerebral hemorrhage (MICH) score, intracerebral hemorrhage grading scale (ICH-GS), and functional outcome (FUNC) score. RESULTS: A total of 2581 patients with spontaneous ICH were enrolled in the study. The max-ICH score was similar or superior to the six existing scores in predicting long-term unfavorable functional outcome after ICH with good discrimination (AUC 0.83, 95% confidence interval [CI] 0.81-0.84) and calibration (Hosmer-Lemeshow P = 0.19). For predicting death, the AUC of max-ICH was 0.81 (95% CI 0.79-0.83). CONCLUSIONS: The easy-to-use max-ICH score is a reliable tool to predict unfavorable long-term (12-month) functional outcome and death after intracerebral hemorrhage in the Chinese population.
