Insights

Cardiothoracic surgery fellows participating in coronary artery bypass grafting (CABG) procedures do not negatively impact clinical outcomes. While operative times and costs slightly increase, patient safety and reimbursement remain unaffected, supporting continued fellow training.

Area of Science:

  • Cardiovascular Surgery
  • Surgical Education
  • Health Economics

Background:

  • Academic institutions face financial pressures impacting trainee involvement in cardiac surgery.
  • Understanding the clinical and financial outcomes of cardiothoracic (CT) fellow participation in coronary artery bypass grafting (CABG) is crucial.

Purpose of the Study:

  • To examine the association between CT fellow involvement and clinical and financial outcomes in isolated, open CABG procedures.
  • To assess the safety and economic implications of training fellows in CABG surgery.

Main Methods:

  • Retrospective analysis of 1997 nonemergent, isolated, open CABG cases (2017-2022) at a single institution.
  • Patients were grouped based on the presence or absence of fellow operative participation.
  • Multivariable regression and generalized estimating equations controlled for patient and surgeon variations.

Main Results:

  • Fellow participation occurred in 31.5% of cases and was associated with a slightly higher preoperative risk score.
  • Fellow involvement correlated with longer total case length (61 minutes) but no significant differences in postoperative clinical outcomes.
  • Hospitalization costs increased by approximately $2200, attributed to longer intraoperative times.

Conclusions:

  • CT surgery fellow participation in CABG is safe, with no adverse impact on clinical outcomes.
  • While operative times and costs show a modest increase, these are not expected to significantly affect reimbursement under bundled payment models.
  • Continued training of CT surgery fellows in CABG is supported by these findings.
