This paper examines the rationality of the concepts underlying evidence—based medicineand health technology assessment (HTA), which are part of a new current aimed at promoting the use of the results of scientific studies for decision making in health care. It describes the different approaches and purposes of this worldwide movement, in relation to clinical decision making, through a summarized set of specific HTA case studies from Catalonia, Spain. The examples illustrate how the systematic process of HTA can help in several types of uncertainties related to clinical decision making.

This article seeks to comment on the approaches to health technology assessment (HTA) outlined in the four main country studies in this volume. It is written from the perspective of a general practitioner working in an inner city area in the United Kingdom and argues that, from the point of view of the clinician, HTA delivers considerably less than it promises. The problems center on the inevitability of judgment by both politicians and clinicians and the conflicting foundations of these judgments. Within political decision-making, the needs of the population inevitably outweigh the needs of the individual; within clinical decision making, the opposite is the case. Attempting a scientific rationality, HTA struggles with the impossibility of holding the balance between the two. These difficulties are further compounded by the implications of ever-increasing expectations of perfect health and the effects of multinational commercial pressures.

The issue of health benefits coverage—and its relation to health technology assessment (HTA)—has gained increasing attention in recent years. Economic constraints on health care, as well as the rapid pace of technological change, have forced European countries to face difficult choices in providing such care. The active use of coverage decision making has been proposed as a tool to help rationalize health care, and HTA has been advocated as a necessary activity to improve coverage decisions.

Since the 1990s, health policy makers in Finland have been supportive of evidence-based medicine and approaches to implement its results. The Finnish Office for Health Technology Assessment (Finohta) has grown from a small start in 1995 to a medium-sized health technology assessment (HTA) agency, with special responsibility in providing assessments to underpin national policies in screening. External evaluations enhanced the rapid growth. In the Finnish environment, decision making on health technologies is extremely decentralized, so Finohta has developed some practical tools for implementing HTA findings. The Managed Uptake of Medical Methods program links the hospital districts to agree on introduction of technologies. The Ohtanen database provides Finnish-language summaries of major assessments made in other countries.

In 1989, Poland started to slowly release itself not only from the burden of a half-century of communist indoctrination and soviet exploitation, but also from the consequences of the Semashko model of healthcare organization: low doctors' salaries, primary care based on multispecialty groups, overdeveloped hospital infrastructure, and limited access to sophisticated interventions overcome by patients' unofficial payments.A few years after the 1998 workshop on health technology assessment (HTA) in Budapest, the first HTA reports were elaborated in the National Center for Quality Assessment in Health Care, which could mark the beginning of HTA in Poland. Several individuals and organizations have been involved in developing HTA, both from noncommercial and commercial standpoints.A goal to establish a national HTA agency appeared among the priorities of the Polish Ministry of Health in 2004 and was realized a year later. The Agency for HTA in Poland published guidelines on HTA and established a sound and transparent two-step (assessment-appraisal) process for preparing recommendations on public financing of both drugs and nondrug technologies. The recommendations of the Agency's Consultative Council were warmly welcomed by the public payer. However, the recent major restructuring of the Agency and new drug reimbursement decisions aroused doubts as to keeping transparency of the decision-making processes.

Within ‘evidence-based medicine and health care’ the ‘number needed to treat’ (NNT) has been promoted as the most clinically useful measure of the effectiveness of interventions as established by research. Is the NNT, in either its simple or adjusted form, ‘easily understood’, ‘intuitively meaningful’, ‘clinically useful’ and likely to bring about the substantial improvements in patient care and public health envisaged by those who recommend its use? The key evidence against the NNT is the consistent format effect revealed in studies that present respondents with mathematically-equivalent statements regarding trial results. Problems of understanding aside, trying to overcome the limitations of the simple (major adverse event) NNT by adding an equivalent measure for harm (‘number needed to harm’ NNH) means the NNT loses its key claim to be a single yardstick. Integration of the NNT and NNH, and attempts to take into account the wider consequences of treatment options, can be attempted by either a ‘clinical judgement’ or an analytical route. The former means abandoning the explicit and rigorous transparency urged in evidence-based medicine. The attempt to produce an ‘adjusted’ NNT by an analytical approach has succeeded, but the procedure involves carrying out a prior decision analysis. The calculation of an adjusted NNT from that analysis is a redundant extra step, the only action necessary being comparison of the results for each option and determination of the optimal one. The adjusted NNT has no role in clinical decision-making, defined as requiring patient utilities, because the latter are measurable only on an interval scale and cannot be transformed into a ratio measure (which the adjusted NNT is implied to be). In any case, the NNT always represents the intrusion of population-based reasoning into clinical decision-making.
