    Abstract:

    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 P 2 = 162, P 2 = 13.4, P = .009). Neither system fully adjusted for the child’s age. The Risk Adjustment in Congenital Heart Surgery scores were more concordant with length of stay compared with Aristotle Basic Complexity scores ( P Conclusions The predictive value of Risk Adjustment in Congenital Heart Surgery is higher than that of Aristotle Basic Complexity. The use of Aristotle Basic Complexity or Risk Adjustment in Congenital Heart Surgery as risk stratification and trending tools to monitor outcomes over time and to guide risk-adjusted comparisons may be valuable.

  • the Aristotle score for congenital heart surgery
    Seminars in Thoracic and Cardiovascular Surgery: Pediatric Cardiac Surgery Annual, 2004

    Abstract:

    The aim of the Aristotle project was to develop a new method of evaluation of quality of care in congenital heart surgery based on the complexity of the surgical procedures. Involving a panel of expert surgeons, the project started in 1999 and included 50 pediatric surgeons from 23 countries representing International Scientific Societies. The complexity was based on the procedures as defined by the Society of Thoracic Surgeons (STS)/European Association for Cadiothoracic Surgery (EACTS) International Nomenclature and was undertaken in two steps: The first step was establishing the Basic Score, which adjusts only the complexity of the procedures and is based on three factors: the potential for mortality, the potential for morbidity, and the anticipated technical difficulty. The second step was the development of the Comprehensive Score, which further adjusts the complexity according to the specific patient characteristics. The Aristotle score allows precise scoring of the complexity for 145 congenital heart surgery procedures. One interesting concept coming out of this study is that complexity is a constant and precise value for a given patient regardless of the center where he is operated. The Aristotle method allows proposing the following equation of quality of care: Complexity FN Outcome = Performance. The Aristotle score, electronically available, was introduced in the EACTS and STS databases. A validation process, designed to evaluate its predictive value, is being developed.
