Assessment of Current Society of Thoracic Surgeons Data Elements for Adults With Congenital Heart Disease

Abstract

Background: To identify opportunities for enhanced data collection for adults with congenital heart disease (ACHD), a structured review of existing variables in The Society of Thoracic Surgeons (STS) Congenital Heart Surgery Database (CHSD) and the STS Adult Cardiac Surgery Database (ACSD) was conducted.

Methods: A working group was assembled representing multiple STS Workforces and Task Forces. The ACSD was reviewed systematically over eight 90-minute calls. ACSD version 4.20.2 and CHSD version 3.41 were used, and the ACSD was approached in sections. ACSD variables were classified as (1) represented in identical form in the CHSD (no further discussion), (2) represented in similar form in the CHSD (discussed for potential harmonization of definitions), or (3) not represented in the CHSD (discussed for potential inclusion). Variables felt to be relevant to ACHD were noted, and special consideration was given to STS required fields and variables used in existing STS adult risk models. Other factors that were examined were the frequency, use, and capture of existing ACSD variables.

Results: Over 22 weeks (8 calls), the existing 1069 variables in version 4.20.2 of the ACSD were discussed. Ultimately, 539 total variables were found to be both (1) relevant to ACHD and (2) not currently collected in the CHSD. These were recommended for inclusion in the next CHSD upgrade for patients aged ≥18 years.

Conclusions: For adult patients having case records entered into the CHSD, the inclusion of a limited set of additional data fields from the ACSD should enhance capture of comorbidities and other clinical data relevant to the ACHD population.
