Methodological and conceptual issues in health care system comparisons: Canada, Norway, and the United States

There is a growing interest in comparison of international health care data with the hope that such studies will enable individual systems to learn from other systems. Such comparisons, however, presuppose that there exist common criteria for evaluating health care systems. The main thesis of this paper is that these comparative studies are misleading because they employ inappropriate operationalizations of these criteria because the operationalizations are based upon mistaken global conceptualizations of the criteria in question. The essay provides a methodological critique of what has been done and sets a new agenda for future research.
