Abstract

Health economics is an area of study that has critical tools for evidence-based healthcare decision making, among which are economic evaluations. These tools allow us to weigh the costs incurred for a given intervention in relation to its health outcomes. The main utility of these studies lies in accomplishing decision-making in healthcare and the formulation of public policies. This article is the first of two reviews on Approaching Economic Evaluations in Health Care Studies, whose main purpose is to address fundamental theoretical concepts of health economic evaluations to facilitate their understanding and critical analysis. The text is part of a methodological series on clinical epidemiology, biostatistics and research methodology conducted by the Evidence-based Medicine team at the School of Medicine of the University of Valparaiso, Chile.
