Abstract

Abstract: Objectives: We sought to assess the safety of training in cardiothoracic surgery comparing outcomes of cases performed by trainees versus fully trained surgeons. Methods: EmBase, Scopus, PubMed, and OVID MEDLINE were searched in August 2021 independently by two authors. A third author arbitrated decisions to resolve disagreements. Inclusion criteria were articles on cardiothoracic surgery reporting on outcomes for trainees. Studies were assessed for appropriateness as per CBEM criteria. Eight hundred and ninety‐two results were obtained, 27 represented best evidence (2‐meta‐analyses, 1‐RCT, and 24 retrospective cohort studies). Results: In all 474, 160 operative outcomes were assessed for 434, 535 coronary artery bypass grafting (CABG) (431, 329 on‐pump vs. 3206 off‐pump), 3090 AVR, 1740 MVR/repair, 26, 433 mixed, 3565 congenital, and 4797 thoracic procedures. In all 398, 058 cases were performed by trainees and 75, 943 by consultants. One hundred fifty‐nine cases were indeterminate. There were no statistically significant differences in the patients' preoperative risk scores. All studies excluded extreme high‐risk patients in emergency setting, patients with poor left ventricular function, and reoperation cases that were undertaken by consultants. There were no differences in cardiopulmonary bypass and clamp times for CABG. Times for valve replacement and repair cases were longer for trainees. There were no differences in the postoperative outcomes including perioperative myocardial infarction, resternotomy for bleeding, stroke, renal failure, intensive therapy unit length of stay, and total length of stay. One study reported no differences on angiographic graft patency at 1 year. There were no differences in in‐hospital or midterm mortality out to 5‐years. Discussion: Trainees can perform cardiothoracic surgery in dedicated high‐volume units with outcomes comparable to those of fully trained surgeons.
