What Seattle Children’s Measures and Why

At Seattle Children’s Heart Center, our outcomes are among the best in the nation for simple to complex heart procedures and transplants for children. Our heart surgeons perform more pediatric cardiac procedures than any other providers in the Washington, Wyoming, Alaska, Montana and Idaho (WWAMI) region.

“Outcomes” refer to the results of treatment and evaluate how effective care is. We also provide statistics such as the number of surgeries performed or patients seen (volumes).

We gather this data to:

  • Measure the health of our patients
  • Improve the quality of the care we provide
  • Help you make informed decisions about your child’s care

This table shows:

  • The number (volume) of each type of complex heart surgery performed at Seattle Children’s Hospital
  • The number of patients who survived more than 30 days after surgery (outcome). “30-day survival” is the measurement for success used by hospitals throughout the nation. Using this measurement allows you to compare us with other hospitals.
