Emerging trends in research on perineal trauma management: A bibliometric analysis of articles published since 1985

Abstract

Background: The purpose of this bibliometric analysis is to explore global trends in scientific research involving spontaneous perineal tears sustained during childbirth. This research is critical as a significant number of women have vaginal lacerations after birth resulting in complications such as pain and pelvic floor dysfunction. Methods: The articles used in this bibliometric analysis were collected from PubMed, Web of Science, Cochrane library and Scopus. Analysis was carried out in Python and R programming languages with some visualizations created using VOS software. Apart from traditional methods, this analysis also involved time series forecasting and assessment of rolling correlations. Results: Results indicate authors and institutions from the United Kingdom as the most productive in the research on this subject research. National level analyses for six countries showed that productivity was positively correlated with GDP/capita, average health expenditure and negatively associated with proportion of C-sections. Recent and emerging themes include those involving pharmacological interventions for pain management. Conclusion: There is a growing global interest in the research on postnatal perineal trauma with authors from the UK playing a leading role so far. Countries with high vaginal birth rates, need to promote research in this field to minimise trauma-associated comorbidities.
