For nearly 15 years The Society of Thoracic Surgeons General Thoracic Surgery Database (STS GTSD) has provided participating institutions with risk-adjusted feedback reports that allow outcome comparisons relative to national benchmarks. With more than 300 contributing centers across North America, the STS GTSD now includes more than 530,000 cases. In 2017 the STS GTSD Task Force revised the data collection form with the goal of collecting more detailed and accurate information for the most important thoracic surgical cases without increasing the workload of registrars. In addition, the learning curve for thoracoscopic lobectomy was examined, online public reporting was initiated, institutional feedback reports were made more user-friendly, and collaboration with the European Society of Thoracic Surgery continued. The STS GTSD Task Force continues to work to improve the quality of care and support research initiatives in general thoracic surgery. This report summarizes current aggregate national outcomes in general thoracic surgery and reviews related activities in the areas of quality measurement, performance improvement, and transparency from the STS GTSD during the past 12 months.
