目的：应用亚里士多德基本复杂性评分表和先天性心脏病手术风险调整量表对先天性心脏病手术效果进行比较。方法：在我所1982-2004年间的所有指标先天性心脏手术中(n=13,675)，我们能够将亚里士多德的基本复杂性评分、先天性心脏病手术中的风险调整评分，这两个评分分别为13,138(96%)、11,533(84%)和11,438(84%)。使用相同的数据集，为亚里士多德先天性心脏病手术的基本复杂性和风险调整建立了住院死亡率和住院时间的模型，其中分配了亚里士多德在先天性心脏病手术中的基本复杂性和风险调整分数。结果：调整手术年限后，亚里士多德基本复杂性评分3分与6分、9分与6分、12分与6分、15分与6分的优势比分别为0.29、2.22、7.62、26.54(P
Objective: The Aristotle Basic Complexity score and the Risk Adjustment in Congenital Heart Surgery system were developed by consensus to compare outcomes of congenital cardiac surgery. We compared the predictive value of the 2 systems.Methods: Of all index congenital cardiac operations at our institution from 1982 to 2004 (n = 13,675), we were able to assign an Aristotle Basic Complexity score, a Risk Adjustment in Congenital Heart Surgery score, and both scores to 13,138 (96%), 11,533 (84%), and 11,438 ( 84%) operations, respectively. Models of in-hospital mortality and length of stay were generated for Aristotle Basic Complexity and Risk Adjustment in Congenital Heart Surgery using an identical data set in which both Aristotle Basic Complexity and Risk Adjustment in Congenital Heart Surgery scores were assigned. The likelihood ratio test for nested models and paired concordance statistics were used.Results: After adjustment for year of operation, the odds ratios for Aristotle Basic Complexity score 3 versus 6, 9 versus 6, 12 versus 6, and 15 versus 6 were 0.29, 2.22, 7.62, and 26.54 (P
