The Society of Thoracic Surgeons Congenital Heart Surgery Database: 2018 Update on Research.

The Society of Thoracic Surgeons Congenital Heart Surgery Database (STS CHSD) is the largest congenital and pediatric cardiac surgical clinical data registry in the world. The most recent biannual feedback report to participants includes analysis of data submitted from 125 hospitals, representing nearly all centers performing pediatric and congenital heart operations in the United States and Canada. In addition to serving as a platform for reporting of outcomes and for quality improvement, the database continues to be a primary data source for clinical research and for innovations related to quality measurement. Over the past year, several investigative teams reported analyses of data in the STS CHSD pertaining to various processes of care, including assessment of variation in specific practices and patient characteristics across centers participating in the STS CHSD, and their associations with outcomes. Additional ongoing projects involve the development of new or refined metrics for quality measurement and reporting of outcomes and center level performance. To meet the needs of investigators, the STS Research Center and Workforce on Research Development has created multiple pathways through which investigators may propose and, ultimately, perform outcomes research projects based on STS CHSD data. This article reviews published outcomes research and quality improvement projects from the past year and describes ongoing research related to quality measurement.
