Complexity

Children's performs a greater proportion of complex surgeries compared to the national average, and our patients still have better outcomes.

What does this data mean?

While there is no simple heart surgery, some heart surgeries are more difficult to perform than others. This graph shows how difficult the surgeries at Children’s were, compared to the national average. Children’s performs a greater proportion of highly complex heart surgeries compared to the national average, and our patients still experience better outcomes. The experience and skill gained in performing highly complex cases enables our surgical team to better care for all our surgical patients.

Why does surgical complexity matter?

Surgical complexity scores allow you to compare outcomes at different centers. We identify the difficulty by assigning each surgery an Aristotle Complexity Score. This score is determined by using three factors:

  • Potential for mortality—the chance of death due to surgery
  • Potential for morbidity—the chance of injury or illness due to surgery
  • Anticipated surgical difficulty—how difficult the surgeon believes the surgery will be

The more difficult and high-risk the operation is determined to be, the higher the complexity score.
