Question: Does what explain the variation in the direct costs of graduate medical education?
Answer: Much of the current variation in residency costs and payments is attributable to accounting and not structural or locational factors. Institutions looking for ways to become more efficient could compare costs of training across institutions without sophisticated adjusters. Federal policymakers should consider a national payment rate per resident to replace the current system based on hospital-specific costs. This proposal would redistribute dollars across residency programs. The proposal would affect payments for direct medical education in the Medicare program and could form the basis for payment for residency education by all payers.
Output:
no
