STS National Database

The STS National Database was established in 1989 as an initiative for quality improvement and patient safety among cardiothoracic surgeons. As of January 1, 2018, the STS National Database has four components, each focusing on a different area of cardiothoracic surgery—Adult Cardiac Surgery, General Thoracic Surgery, and Congenital Heart Surgery, as well as mechanical circulatory support via the Intermacs Database. The Database has grown exponentially over the years, both in terms of participation and stature.

What's New

February 2019 ACSD Training Manual Updates

The latest training manual published on the ACSD Data Collection page contains important information to help with data abstraction. Key changes are noted below, including some that are retroactive to January 1, 2019.

  • Bedside spirometry is now allowed to be used if NOT read by a pulmonologist. Please make this adjustment starting with January 1, 2019 cases.
  • Leave the carotid stenosis field blank for carotid dissections. The only exception is if the internal carotid is totally occluded as a result of the dissection. For cases where dissection resulted in occlusion, please submit details to the FAQ Mailbox for clarification/verification. 
  • New valves that are not on the Valve/VAD list will be added with the next ACSD version upgrade. Until that time, please enter "Other FDA-Approved" or "Other Non FDA Approved" as appropriate.

STS is now offering a mentorship program for data managers. Experienced data managers will be paired with those who are seeking advice related to data abstraction. Sign up as either a mentor or mentee.
