Economic studies part 2: evaluating the quality.

Abstract

There are many opportunities for bias in economic evaluations. Thus, critical appraisal of economic studies is very important but complex. No standard methodology for appraisal has been universally adopted. However, consideration of the common elements that constitute a high-quality economic study provides the clinician with the tools to understand when one might be dealing with a high-quality study, a deeply flawed one, or one that made the best use of the data available. Studies of economic impact have become increasingly important in health policy decisions given the finite resources available for health care. While they should not be the sole basis of decision making, such studies provide potentially valuable information if well done. It is therefore important that high-quality economic studies be conducted and the results of economic studies be placed in the context of their quality.
