Summary of the Discussion
I would like to summarize the main messages from the economic studies that have been presented here today. For me, the most important message of all is the fact that people, at long last, are measuring costs and are beginning to consider costs in relation to the benefits of various medical treatments. Costs have attracted sufficient attention for physicians, as well as administrators, to try to measure the true resource costs of the treatments that we offer. I want to reem-phasize the importance of differentiating between resource costs and charges. In the United States, at least, any relationship between charges and costs may be purely coincidental.
