The argument for expanding the physician workforce is based on a faulty assumption, according to the authors. Proponents reason that the practices of the highest-intensity medical centers where many more doctors and resources are used in providing medical services at the end of life, should be the standard for the country as a whole. "Instead of financing further growth in our medical education system, resources might be better directed to reorganizing delivery systems that have already demonstrated that they can deliver good care at relatively low cost," the authors write.
