Highlights
● Publications related to body weight measurement in critically ill patients have increased substantially over the last 20 years.
● Based on the subject area analysis of 1423 published articles, 65.5% were related to “medicine” and 14.1% to “nursing.”
● Keyword analysis revealed 6 clusters, with the most frequent keywords being “critical illness,” “hospital admission,” “body weight,” “artificial ventilation,” “intensive care unit,” and “sequential organ failure assessment.”
● Potential topics based on research gaps included “hemorrhage,” “ground glass opacity,” “artificial feeding,” “mathematical analysis,” “blood urea nitrogen,” “net ultrafiltration,” “kidney function test,” “cross-infection,” and “virus load.”
● The insufficient research output, particularly in the Middle East and Southeast Asia, presents a significant opportunity for growth.
Plain Language Summary
Body weight measurement and documentation are crucial for determining the appropriate care for critically ill patients. This study used bibliometric analysis to track trends in body weight measurements of critically ill patients. This approach helps identify dominant research themes and emerging areas of interest. The results showed that publications on body weight measurement in critically ill patients have increased markedly over the past two decades. An analysis of 1423 published articles revealed that 65.5% focused on “medicine,” whereas 14.1% were associated with “nursing.” The United States led globally with 457 publications, while the Middle East and Southeast Asia had insufficient research output. Cluster analysis using VOSviewer, identified six 6 primary research themes, each with frequent keywords related to the research. This study also utilized the RStudio package with biblioshiny to present the growth of publications and a thematic map of the studies. These findings indicate a growing body of research in this field, predominantly focusing on critical care and highlighting the potential for more nursing research topics related to body weight measurement in critically ill patients. This research gap also presents an essential opportunity to expand more inclusive global research networks that can contribute to improved health management related to body weight measurement for critically ill patients.
