The Society of Thoracic Surgeons Congenital Heart Surgery Database: 2024 Update on Outcomes and Research.

Since its inception in 1994, The Society of Thoracic Surgeons Congenital Heart Surgery Database (CHSD) has established itself as the largest congenital and pediatric cardiothoracic surgical clinical data registry in the world, containing data from 677,684 operations as of 2023. The CHSD collects detailed clinical data and undertakes risk-stratified and risk-adjusted analysis using statistically robust high-fidelity risk models. The 37th data harvest analysis in Spring 2024 demonstrated an aggregate mortality of 2.6% in the CHSD. Survival in all benchmark operation groups continues to improve. An educational audit mechanism ensures the validity and accuracy of data collected in the CHSD. CHSD data continue to be used in important research endeavors that shape the practice of congenital cardiothoracic surgery. CHSD data fields and analytics are constantly refined to ensure that they remain contemporary. These efforts will continue to support quality and process improvement, ultimately allowing us to provide better care for our patients.
