An evolutive and scientometric research on tissue engineering reviews

Abstract

Publication numbers have been widely used as measure of research output, especially academic and university research. Publication numbers in tissue engineering (TE) have increased year by year since early 1990s. However, after an exponential growth phase, recently publications increase at lower rates, suggesting a consolidation process in which reviews become a relevant and high evidence document type. The aim of this study is to perform a scientometric evaluation of published literature reviews on TE in order to assess the status of scientific evolution and confirm the consolidation of TE as a research area. Published reviews on TE from 1991 to 2018 were retrieved from Web of Science core collection and this corpus of knowledge was analyzed by growth rate, research area, source title and citation. Our results revealed that TE can be considered a consolidating area as it leaves the forefront stage of a gompertzian growth curve model. Original research/review ratio is lineally decreasing during the last decade. The emergence of reviews serves to confirm and refute hypothesis and build up a more reliable theoretical framework as well as a guide for future educational approaches. Distribution assessment of categories and journals indicates the multidisciplinary profile of this area focused on the design and development of new tissues. Biomedical sciences become relevant productors of reviews to as they need to support TE innovations with high evidence leading to a safer and more efficient treatment of current injuries and diseases.
