Study on Differences between Efficacy and Effectiveness in Clinical Evaluation
Abstract:Both “efficacy” and “effectiveness” are two important terms which express distinctly different concepts in clinical therapeutic effect evaluation. In this article, the distinctions and relationships between the two connotations are expounded, and both the differences between “explanatory randomized controlled trials(ERCT)” and “pragmatic randomized controlled trials(PRCT)”,which are respectively corresponding to “efficacy” and “effectiveness”, and their applicative values in different stages in clinical therapeutic effect evaluation are further explored. The results of this study may take the role of a helpful reference for clinical therapeutic effect evaluation of traditional Chinese medicine to define research purposes, to locate appropriate research stages, and to choose suitable designs at its different stages.
