A new master's program offered by Vanderbilt University's Owen Graduate School of Business is part of a national trend to equip doctors, nurses, and others with more knowledge about the dollars-and-cents side of healthcare. The University of Tennessee and Meharry Medical College are other schools with similar courses or degree programs aimed at improving the financial knowledge of the medical community. During a recent Saturday on Vanderbilt's campus, professor Larry Van Horn used a discussion of the medicines that his son takes to explain how consumer choices about drugs might change if people had to pay full price for medicines without insurance discounts.
