title: Best medical practice in practice: measuring efficiency in mammography screening.
abstract: Breast cancer, screening and mammography have caused considerable debate in several countries. This article explores the concept of best medical practice in the context of mammographic screening for breast cancer. Maximizing the use of technology, ignores the risks intrinsic to technological intervention. To do no harm in modern medical practice means largely doing nothing. Best medical practice, therefore, requires a balancing of benefits and risks so that best practice is that which does more good than harm. At the same time, not all interventions that do more good than harm can be funded out of the current health care budget. Thus, best medical practice is economically efficient practice. From the conceptual notion of what is best medical practice, this article turns to the problem of what that means in practical terms. Can we recognize best medical practice when it occurs? The identification, measurement and valuation of costs and benefits are discussed as a specific case study, in the context of breast cancer screening. Many of the difficulties involved here, particularly on the benefit side, are highlighted, especially in the context of QALYs. Yet, whatever the difficulties involved they have to be seen in the context of otherwise settling for something less i.e. inefficient medical practice.
