Global research trends on sepsis and septic shock during 2003–2022: A data-driven bibliometric analysis

Abstract

Abstract Background Sepsis is a major medical condition that contributes to substantial morbidity and mortality rates worldwide. Research to better understand and manage these complex conditions has intensified over the past two decades. This bibliometric analysis aims to map global research trends in sepsis and septic shock from 2003 to 2022, providing insights into the evolution of the field. Methods This study conducted a comprehensive search for publications on sepsis and septic shock using the Web of Science Core Collection. Data were analysed using VOSviewer for bibliometric mapping, focusing on publication trends, country, institutional contributions, journal sources, citation analysis, and keyword co-occurrence. Results In total, 78,108 publications were retrieved, with a notable increase in annual output over the study period. The United States ranked first in publication volume, followed by China, Germany, and the United Kingdom. Harvard University was the most prolific institution. Critical Care Medicine emerged as the leading journal in terms of publication count. The most cited articles and references were predominantly related to definition, epidemiology, and management guidelines for sepsis. Recent research hotspots included COVID-19, machine learning applications, NLRP3 inflammasome, autophagy, gut microbiota, and microRNA (miRNA). Conclusions Our bibliometric analysis identifies global research trends in sepsis over the past 20 years, with evolving hotspots and increasing global collaboration. Key findings highlight continuous efforts to understand the complex pathophysiology of sepsis and septic shock. COVID-19, machine learning applications, NLRP3 inflammasome, autophagy, gut microbiota, and microRNA (miRNA) are hotspots.
