Economic evaluation of drugs and its potential uses in policy making.

Interest in the economic evaluation of drug treatments is steadily increasing, but the impact of such evaluations on decisions concerning the use of drugs is unclear. In this article I examine different decision and policy situations where economic evaluations of drug treatments could potentially be used. Economic evaluations may be used as an aid to the development of treatment guidelines, decisions within healthcare organisations, and decisions relating to approval, reimbursement and pricing. Economic evaluations appear to be most useful in the development of treatment guidelines and as an aid to reimbursement decisions. The incentive to use economic evaluations embodied in the healthcare system is also important. It is argued that it is too early to introduce regulations that require the use economic evaluations in, for example, reimbursement decisions. A more cautious approach might be preferred, where economic evaluations are used more selectively until the methodology and the field have developed further.
