Children’s Heart Institute has earned a distinguished three-star rating, the highest rating available, from The Society of Thoracic Surgeons (STS) for its patient care and outcomes in congenital heart surgery. As one of only 12 three-star programs of the STS’s 119 participating programs, Children's Heart Institute ranks among the elite in the United States and Canada for congenital heart surgery.

Each year, participating centers submit their data to the Society of Thoracic Surgeons (STS), Congenital Heart Surgery Database (CHSD), to compare their outcomes against STS national benchmarks. Below is an overview of Children’s Heart Institute’s surgical outcomes data from January 1, 2014 – December 31, 2017.

What Does Risk Adjustment Mean?

The STS uses a mortality risk model to allow for more meaningful comparison of any given hospital to the total of all hospitals performing pediatric and congenital heart surgery and participating in the CHSD. Risk adjustment is a method of measuring surgical results that takes into account how sick patients were before treatment. Hospitals that treat medically complex patients are expected to have higher rates of mortality according to the STS, which may be due to the patient’s condition or the procedural complexity required to treat them. The CHSD mortality risk model accounts for specific variables such as age and preoperative factors when comparing Centers, all of which can affect surgical results.

STAT Category

The STS classifies cardiac cases into five categories, 1 – 5, based on complexity of the procedure. Category 1 is the least complex and Category 5 is the most complex with the highest risk of mortality (death). The affiliated team of board-certified pediatric and congenital heart surgeons treats the full spectrum of pediatric and congenital heart conditions, from the simplest to the most complex.

Volume and Mortality Rate by STAT Category

The STS mortality metrics are risk-adjusted to allow for more level comparison of any given hospital participating in the database with factors such as acuity, complexity and comorbidities taken into account.

MORTALITY BY STAT CATEGORY (January 2014 - December 2017)

STAT Category Number of Procedures Number of Mortalities % Mortality STS National Benchmark
Category 1 210 1 0.5% 0.4%
Category 2 246 5 2.0% 1.6%
Category 3 89 0 0.0% 2.3%
Category 4 189 11 5.8% 6.4%
Category 5 53 4 7.5% 14.5%

Index Procedure Volume and Mortality Rate

The data below shows Children’s Heart Institute’s heart surgery volume and mortality rate by procedure type. Overall, having a lower mortality rate than the STS national benchmark is optimal. Children’s Heart Institute’s unadjusted mortality rate (2.7%) is less than the national average (2.9%).

INDEX PROCEDURE VOLUME AND MORTALITY RATE (January 2014 - December 2017)

Index Procedure Number of Procedures Number of Mortalities % Mortality STS National Benchmark
Arterial switch operation (ASO) 20 0 0.0% 2.2%
ASO + VSD Repair 10 0 0.0% 4.6%
Atrioventricular canal repair (AVC) 26 0 0.0% 2.5%
Coarctation 48 1 2.1% 1.5%

Ventricular Septal Defect (VSD) Repair 66 0 0.0% 0.5%
Tetrology of Fallot 60 3 5.0% 1.3%

*Note: Operative Mortality is defined as any death, regardless of cause occurring (1) within 30 days after surgery in or out of the hospital, and (2) after 30 days during the same hospitalization subsequent to the operation. Source: STS Database, Table 18
