[Pharmaco-economic evaluations of new drugs: potential key to a more efficient allocation of the health care budget].

In the light of rising expenditure on drugs and health care, a transparent, rational and careful decision-making process is required for the reimbursement of drugs. In the Netherlands, the Ministry of Health intends using pharmaco-economics in this process, i.e., new drugs will not only be judged on their clinical efficacy but also on their cost-effectiveness. Guidelines for pharmaco-economic research in the Netherlands have been published. According to these guidelines, a pharmaco-economic study must contain a cost-effectiveness analysis and/or a cost-utility analysis. In addition, a budgetary impact analysis is required. By 2005, all new drugs with therapeutic added value must supply a pharmaco-economic evaluation in order to apply for reimbursement. It will be the Minister of Health who decides whether a new drug will be reimbursed.
