Risk-adjusted surgical survival rates

Why we measure it - We perform the entire spectrum of pediatric heart surgeries at the Herma Heart Center, from straightforward procedures to very complex operations. We categorize each type of surgery by using the risk adjustment congenital heart surgery (RACHS) classification system. Our survival rates for more complex surgeries are among the nation's highest based on peer comparison information from the Society of Thoracic Surgeons.

 What this means - Surgeries with lower group numbers are considered less risky and have higher survival rates. Surgeries with larger group numbers are considered riskier and more complicated and survival rates may decrease. Herma Heart Center has higher or equivalent survival rates for children undergoing heart surgery than the Society of Thoracic Surgeon's national averages in all group RACHS-1 categories.

About the data - RACHS stands for risk adjustment for congenital heart surgery and is a system used to classify heart procedures. Group 1 represents the most straightforward procedures and Group 5 represents the most complicated. RACHS-1 categories are based on the Aristotle Basic Complexity Level. The data displayed are survival percentages for all heart surgeries performed from July 2008 through June 2012 at Children's Hospital of Wisconsin in Milwaukee as compared to survival percentages for Society of Thoracic Surgeon peers.

How we provide the best care

  • All Herma Heart Center cardiothoracic surgeons are board-certified in Congenital Heart Surgery by the American Board of Thoracic Surgery. They are the only ones in Wisconsin to have earned this distinction. They are also consistently named among the Best Doctors in America.
  • Our specialists accept the most complex patient cases and our Herma Heart Center is one of top referral centers in the country.
  • Our Interstage Home Monitoring Program helps dramatically improve infant survival rates after patients are discharged from the hospital following heart surgery.
  • Our registered dietitians have developed effective nutritional feeding plans to promote normal weight gain for babies before and after heart surgery.
  • Our Neurodevelopmental Follow-up Program offers early intervention services for infants and toddlers that have had heart surgery. A highly specialized developmental pediatrician coordinates care and evaluates your child during each visit.
