Basic Methods of Health Technology Assessment

Health technological innovation has helped to improve health care delivery and patient outcomes. However, the proliferation of health care technology has accompanied burgeoning health care costs and evoked social, ethical, legal, and political concerns. Health technology assessment (HTA) is the systematic evaluation of properties, effects and/or other impacts of health care technology. The main purpose of HTA is to inform persons of technology-related policy making in health care. There is great variation in the scope, selection of methods and level of detail in the practice of HTA. This paper will introduce the basic concepts and methods of HTA in order to help those who are interested in conducting HTA.
