Ethical perspectives on health technology assessment.

This study analyses why ethical aspects play a minor role in health technology assessment (HTA) studies, even when comprehensive approaches of technology assessment are advocated. Technology is often regarded as a value-neutral tool. At the same time, bioethics is dominated by an engineering model. Ethical contributions to evaluation of medical technology should go beyond issues of application in clinical practice and focus also on the definition of problems, the demarcation of technical and nontechnical issues, and the morally problematic implications of technologies.
