STS National Database

The STS National Database was established in 1989 as an initiative for quality improvement and patient safety among cardiothoracic surgeons. There are three components to the STS National Database, each focusing on a different area of cardiothoracic surgery—Adult Cardiac, General Thoracic, and Congenital Heart Surgery, with the availability of Anesthesiology participation within the Adult Cardiac and Congenital Heart Surgery Database components. The Database has grown exponentially over the years, both in terms of participation and stature.

Mortality Status Thresholds for Composite Quality Ratings

In order to assure the highest level of accuracy when reporting operative mortality in the STS National Database, the following data thresholds are being implemented to determine eligibility for a composite score (star rating):

  1. Cases performed January 1–December 31, 2015 must have a 90% completeness threshold for fields related to operative mortality status.
  2. For all cases performed on or after January 1, 2016, the operative mortality fields must have a 95% completeness rate.
  3. For all cases performed on or after January 1, 2017, the operative mortality fields must have a 98% completeness rate.

Participants who do not meet the data completeness thresholds will not be eligible to receive a composite score (star rating) from the affected data harvest.
