Heart Surgery

Surgical Volume & Outcomes

 

The Cardiothoracic (CT) Surgery Team at Phoenix Children's Hospital is always striving to improve patient safety and outcomes. One way we achieved this is by participating in the Society of Thoracic Surgeons (STS) Congenital Heart Surgery Database. This database provides a detailed report of our heart surgery program and compares our performance to other programs in North America.

In early 2015, the STS initiated voluntary public reporting and Phoenix Children's Hospital was one of the first participating programs. The STS public reporting initiative has awarded Phoenix Children's Hospital a 3-star rating, the highest rating, because the risk adjusted mortality rate for cardiothoracic operations performed from 2011-2014 was statistically lower than the STS expected mortality rate. Phoenix Children's Hospital was one of 6 programs in North America to receive the 3-star rating out of 116 participating programs. Subsequent analyses of the database have yielded the same 3-star rating. More information regarding public reporting can be found on the STS website.

The volumes and outcomes reported below are derived from the most recent data analysis report from the STS dated Spring 2015 and includes cardiothoracic operations from January 1, 2011 ending December 31, 2014. Our data is reanalyzed every 6 months to allow for recent volumes and outcomes to be included and reported. The procedure volumes below are representative of all CT surgery operations performed at Phoenix Children's Hospital.

The CT Surgery Team at Phoenix Children's Hospital believes the public has a right to know how well our program is performing. The data presented in this section is obtained directly from the data reports provided by the STS Congenital Heart Surgery Database.

Cardiothoracic (CT) Surgery Total Volume by Operation Type

The CT Surgery Program at Phoenix Children’s Hospital is considered a high volume program as we perform greater than 250 cardiac surgery operations each year. Research studies support that there are less patient deaths following heart surgery in programs that perform higher numbers of operations on highly complex patients as compared to low volume programs.

CT Surgery Total Volume by Operation Type

Operation Types - CPB: Operations where cardiopulmonary bypass was used; Non-CPB CV: cardiac operations where cardiopulmonary bypass was not used; Thoracic: operations on the lungs or chest structures; VAD: ventricular assist device; ECMO: extracorporeal membrane oxygenation; Minor: operations not involving the major structures of the heart and lungs.

CT Surgery Volume by Year

CT Surgery Volume by Year

Procedure volume includes all cardiothoracic surgery operations performed at Phoenix Children’s Hospital. Volumes are based on the division administered database and data analyses of the STS Congenital Heart Surgery Database.

CT Surgery Total Volume by Age

The CT Surgery Team at Phoenix Children's Hospital operates on patients with congenital heart disease from birth through adulthood.

CT Surgery Total Volume by Age

Age of patients at time of surgical procedure.

  • Neonate: 0 – 30 days
  • Infant: 1 month – 12 months
  • Child: 1 year – 18 years
  • Adult: 18 years and older

CT Surgery Survival Rate by Year

The overall survival rate at PCH following cardiothoracic surgery is statistically higher than the average survival rate reported by the STS Congenital Cardiothoracic Database.

Risk Adjusted Mortality Rates

The STS Congenital Heart Surgery Database analyzes reported operations, taking into account the complexity of the patients in a surgical program. This tells us how well we are performing as compared to other hospitals by reporting whether our patient survival is better or worse than expected given how complex the patients are at Phoenix Children's Hospital.

Risk Adjusted Mortality Rates 
*Denotes statistically significant difference from the STS mortality rate

The observed number of surgical mortalities at PCH is less than the expected number of mortalities given the complexity of the patients we are operating on.

Survival Rates by STAT Mortality Category

The Society of Thoracic Surgeons Congenital Heart Surgery Database in collaboration with the European Association for Cardio-Thoracic Surgery (EACTS) developed a method to compare mortality rates between programs by the difficulty of the operation. The STAT Mortality Categories (STAT) divide operations into 5 categories, 1 – 5 in order of increasing difficulty. The most technically difficult procedures (STAT Categories 4 and 5) with the lowest survival rates are reported in the table below.
