We evaluated the relation between race and economic status of surgical patients and their likelihood of being treated by a surgeon in training rather than by a staff surgeon. Blacks were 2.2 to 4.3 times more likely than whites to be under the care of surgeons in training (P<0.001). This relation has remained unchanged over the past two decades. It remained when the method of payment was via self-payment or private insurance, but disappeared when patients being paid for by Medicaid were considered. In addition, black emergency patients were more likely than white emergency patients to be cared for by surgeons in training. (N Engl J Med 297:90–91, 1977)
