Development of a Congenital Heart Surgery Composite Quality Metric: Part 2-Analytic Methods.

ABSTRACT:

Background

We describe the statistical methods and results related to development of the first congenital heart surgery composite quality measure.

Methods

The composite measure was developed using The Society of Thoracic Surgeons Congenital Heart Surgery Database (2012 to 2015), Bayesian hierarchical modeling, and the current Society of Thoracic Surgeons risk model for case-mix adjustment. It consists of a mortality domain (operative mortality) and morbidity domain (major complications and postoperative length of stay). We evaluated several potential weighting schemes and properties of the final composite measure, including reliability (signal-to-noise ratio) and hospital classification in various performance categories.

Results

Overall, 100 hospitals (78,425 operatio
