Characteristics of cardiothoracic surgeons practicing at the top-ranked US institutions

BACKGROUND: We aimed to determine which factors distinguish cardiothoracic (CT) surgeons practicing at the top-ranked US institutions from their peers. METHODS: Using online resources, we collected demographics, training information and academic metrics of 694 cardiac (n=489; 70%) and thoracic (n=205; 30%) surgeons practicing at 57 preeminent US institutions, including those with the highest US News & World Report ranking ("top CT centers"). RESULTS: Two hundred and ninety-nine (43.1%) CT surgeons were practicing at the 18 "top CT centers" and had higher academic productivity (publications, citations) than their peers. While there was no difference in the proportion of international medical graduates (IMGs) (21.4% overall) or of surgeons with a PhD degree (9.4% overall) across institutions, the "top CT centers" had a higher proportion of faculty who received their entire CT training abroad (10.4% vs. 5.8%; P=0.038) or at highly-ranked US institutions. Those who published more during their early career years (residency, fellowship and first 5 years as faculty) were more likely to attain academic (professorship) and institutional leadership (division/department chair) positions and to practice at the "top CT centers". Women represented a minority (7.3% overall; 5.1% of cardiac vs. 12.7% of thoracic surgeons, P
