STS Database Penetrance in USA
The STS Congenital Heart Surgery Database (STS-CHSD) is the largest
clinical database in the world for congenital and pediatric cardiac
surgery.
The Report of the 2010 STS Congenital Heart Surgery Practice and
Manpower Survey, undertaken by the STS Workforce on Congenital Heart
Surgery, documented that 125 hospitals in the United States of America
and 8 hospitals in Canada perform pediatric and congenital heart
surgery.
The STS-CHSD contains data from 120 of the 125 hospitals (96%
penetrance by hospital) in the United States of America and 3 of the 8
centers in Canada.

Adjustment for Case Mix
“Differences in medical outcomes may result from
disease severity, treatment effectiveness, or
chance.
Because most outcome studies are observational….
risk adjustment is necessary to account for case mix”

Risk stratification
Risk stratification is a method of
analysis in which the data are
divided into relatively
homogeneous groups (called
strata).

Procedure-specific mortality rate estimates were calculated using a Bayesian model that adjusted for small denominators.
Operations were sorted by increasing
risk and grouped into 5 categories that
were designed to • minimize within-category variation
and
• maximize between-category variation

Coefficients obtained via shrinkage estimation with The Society of Thoracic Surgeons–European Association for Cardio-Thoracic Surgery (STS-EACTS [STAT]) Mortality Category as an auxiliary variable. c CPS = cardiopulmonary support; ECMO =extracorporeal membrane oxygenation; IABP = intraaortic balloon pump; VAD = ventricular assist device

Basic Principles

2. Patients and their families have the right to
know the outcomes of the treatments that

3. It is our professional responsibility to share
this information with them in a format that they
can understand.
Basic Principles
The solution to risk aversive behavior is proper risk adjustment.
The solution to fear of stifling innovation is proper risk adjustment.
Our tools for public reporting are not perfect, but they are the BEST available (and these tools will improve)…..
Adjusted Mortality Rates (AMR’s)
The adjusted mortality rate (AMR) is an estimate
(based on a statistical model) of what the hospital’s
mortality rate would be if its observed
performance was extrapolated to the overall STS
case mix (specifically, the mix of age, weight,
procedure types, and other model specific variables
including prior cardiothoracic operations, non-
cardiac congenital anatomic abnormalities,
chromosomal abnormalities, syndromes, and
preoperative risk factors).
Adjusted Mortality Rates (AMR’s)
AMR is calculated by the following
formula:
AMR of hospital = O/E ratio of hospital x
overall observed STS mortality rate*.
If O/E x STS mortality rate is greater
than 100%, the AMR is set to 100%.
Ongoing Refinement in Risk Model
1. Coefficients are updated every 6 months
2. Specific coefficients being developed for:
– Non-cardiac Congenital Abnormalities
– Chromosomal Abnormalities
– Syndromes
3. Multi-domain composite
– Mortality
– Major morbidity
– Postoperative Length of Stay
