Summary

A new complexity score, the Aristotle Score, is being developed to objectively analyze surgical outcomes in congenital heart surgery. This tool will help stratify risk and improve quality of care evaluations.

Area of Science:

  • Cardiovascular Surgery
  • Medical Informatics
  • Health Services Research

Background:

  • Surgical quality of care evaluation is evolving, with scientific societies likely to mandate self-assessment.
  • Accurate quality assessment requires standardized nomenclature, registries, and risk stratification.
  • Current registries lack the ability to reliably stratify surgical risk based on pathology complexity.

Purpose of the Study:

  • To develop a novel risk stratification method for congenital heart surgery.
  • To enable objective analysis of surgical outcomes by accounting for pathology complexity.
  • To address the limitations of existing registries in differentiating outcomes for complex cases.

Main Methods:

  • Development of a "complexity score" based on expert opinion from 50 international surgeons.

  • Hierarchical classification of surgical procedures by mortality, morbidity, and difficulty.
  • Scoring of procedures globally for simple pathologies and in detail across seven risk categories.

    • Main Results:

    • A new risk stratification tool, the Aristotle Score, has been developed for congenital heart surgery.
    • The score aims to provide objective analysis of surgical outcomes relative to pathology complexity.
    • This method addresses the deficit in risk discrimination within current surgical registries.

    Conclusions:

    • The complexity score (Aristotle Score) is a novel approach to risk stratification in congenital heart surgery.
    • It is being developed collaboratively by major international cardiothoracic surgery associations.
    • The score is anticipated to improve the reliability of quality of care evaluations and encourage reporting from complex centers.
