Growth of for-profit involvement in emergency medicine graduate medical education and association between for-profit affiliation and resident salary.

We found a substantial growth of newly ACGME accredited for-profit affiliated EM residency programs from 2016-2021. We also found for-profit affiliated programs pay lower PGY1 salaries than nonprofit-affiliated programs after controlling for potential confounding variables, which suggests more oversight over the salary determination process could be necessary to prevent resident underpayment.
