The reports presented below compare the outcomes of various procedures performed at Stanford Health Care (SHC) to that of the national averages as reported by the Society of Thoracic Surgeons (STS). Unless noted otherwise, this data is risk adjusted, meaning it takes into account the preoperative risk factors and co-morbidities of a specific hospital and patient, and then compares outcomes between the performance of the hospital and that of the national average. This risk-adjustment method levels the playing field for a valid comparison between hospitals regardless of the severity of the patients they treat.

This report reflects the 30-day mortality rate for this group of the most commonly performed cardiac procedures for the average national patient coming to Stanford Health Care (SHC) for an operation. Patients coming to Stanford Health Care consistently have a decreased chance of mortality as compared to the average national hospital.
