Professor Hall is to be congratulated on his thoughtful analysis of an issue that, as he rightly suggests, “is one of the most important issues that will confront health care tort law throughout the remainder of the century.”’ He argues that malpractice law currently can accommodate considerable latitude both for a conservative streamlining of medical practices in general and for a cost-sensitivity in individual treatment decisions. And he further argues that existing tort principles, such as the locality rule, can comfortably (...) be stretched to embrace still greater room for economics in the medical standard of care. I quite agree.Unfortunately, Hall's arguments do not go nearly far enough, for they are framed around a seriously oversimplified picture of the economic changes that are revolutionizing medicine in the United States. He envisions a fairly uniform, global set of resource constraints that generally pressure physicians to conserve on care—pressures that tort law can then encompass equally globally as it accepts more cost-efficient standards of care. However, neither the changing economics of medicine nor the resulting jurisprudential challenges are anywhere near this generalized. (shrink)
