Data Source
The STS started collecting prospective data for the GTSD in 1999 and began issuing reports in 2002. At the time of the latest report, there were 58 participating sites (hospitals, group practices or individual surgeons) and 225 individual surgeons who voluntarily submitted data to the STS GTSD. After annual data harvests, each participant receives a data quality report with the opportunity to amend missing or aberrant data. Data submissions are checked for completeness and compliance within
Results
Patient characteristics are listed in Table 2. There were a similar number of men and woman. Additional comorbidities in the cohort of 4979 patients included a body mass index (BMI) exceeding 30 in 1186 of 4463 (27%), congestive heart failure in 157 (3%), coronary artery disease in 991 (20%), peripheral vascular disease in 452 (9%), cerebral vascular disease in 393 (8%), hypertension in 2659 (53%), and prior thoracic operations in 631 (13%). Comorbidities were present in 4006 patients (80%),
Comment
The STS introduced its thoracic database in 2002 with the intent of using it to continuously measure and improve the quality of thoracic surgical care in North America. After collection of data for more than 50,000 procedures and nearly 5000 lobectomies, the feasibility of risk-prediction models to compare outcome among participating institutions and surgeons has been demonstrated. In the first report of standard resections for lung cancer with data from the STS database, Boffa and associates [6
