High tech, low yield: doctors' use of medical innovation.

Abstract

American physicians' tendency to test too much and do too much is a major force in the rapid diffusion of medical technology. To manage medical technology humanely and responsibly, we must establish a basis for assessing the benefits and costs that will enable us to make rational coverage and payment decisions. We must also devise a means of holding providers of care accountable for weighing the benefits and costs in using the technology.
