Fig 1 Data on mortality are displayed as a funnel plot for The Society of Thoracic Surgeons–European Association for Cardio-Thoracic Surgery (STS-EACTS [STAT]) category 5 operations [26]. The horizontal dashed line depicts STS aggregate mortality before discharge. Dashed lines depicting exact 95% binomial prediction limits were overlaid to make a funnel plot. Squares represent the number of cases and mortality before discharge for individual STS Congenital Heart Surgery Database participants (centers). This analysis includes patients undergoing surgery during the 5-year analytic window of 2005 to 2009, inclusive, and includes 70 STS centers in the STS Congenital Heart Surgery Database and 2,707 operations. Centers that were identified as outliers represented 18.6% of participating centers (13 of 70): 10% (7 of 70) were “high-performing outliers” and 8.6% (6 of 70) were “low-performing outliers.” Quality improvement initiatives can be initiated in low-performing centers, and best practices can be obtained from high-performing centers.
