2. Fig 1
Increasing center level penetration in The Society of Thoracic Surgeons (STS) Adult Cardiac Surgery Database (ACSD). This graph only provides data through 2012 because, at the time this article was written, 2012 was the last year of available linked data from the linkage of STS ACSD and the Centers for Medicare and Medicaid (CMS) Medicare database. Linkage for 2013 data is now under way and will likely show continued increasing penetration [3].

Annual growth of The Society of Thoracic Surgeons (STS) Congenital Heart Surgery Database by number of participating centers submitting data. The aggregate feedback report from Spring 2015 harvest of the STS Congenital Heart Surgery Database includes data from 116 North American congenital database participants representing 127 congenital heart surgery hospitals in North America, 124 in the United States and 3 in Canada.

Increasing participation in The Society of Thoracic Surgeons (STS) General Thoracic Surgery Database. (A) Participating centers. (B) Participating surgeons. Note: number of surgeons counts surgeon/participant pairs; if a single surgeon is associated with more than one participant, he or she is counted more than once in this total.
