Trends and hotspots in burns-related pain research: A bibliometric analysis

The aim of this investigation was to conduct a thorough synthesis of the extant scholarly discourse and to delineate the prevailing global trends in the domain of burn pain, employing a bibliometric analysis.

A bibliometric analysis was performed utilizing the Web of Science Core Collection database. Articles were selected based on titles or abstracts containing keywords associated with burns and pain. Both quantitative and qualitative methodologies were applied to examine the retrieved data, encompassing an analysis of publication trends, research themes, and collaboration networks.

The number of articles on this topic has been increasing, averaging an annual growth rate of 6.9 % from 1997 to 2023. Contributions have come from 645 institutions across 53 countries, resulting in 446 papers that span areas such as nursing, anesthesia, and immunology. Key journals include Burns, Journal of Burn Care & Research, and Pain. The United States has demonstrated a significant research output in this field, with active international collaboration, notably with Washington University leading in contributions. Patterson DR was the most prolific author in terms of published papers, while Choiniere M was the most frequently co-cited author. The focus of research has shifted from symptom management to exploring pain mechanisms. Current research priorities in burn pain include "quality of life," "music therapy," and "psychological state." Recent analysis has highlighted key areas in neuropathic pain mechanisms, novel analgesic therapies, and specific groups such as pediatric burn patients. Influential studies have advanced our understanding of pathophysiology, while psychological interventions and inflammation are increasingly receiving attention. Emerging topics include non-pharmacological interventions, psychological support, technology in pain assessment and management, quality of life, and personalized pain management.

Research on burn pain is advancing rapidly; however, collaboration among countries and institutions remains limited. Increased cooperation and communication across these entities could significantly advance the field in the future. Future research should prioritize placebo-controlled trials of targeted therapeutic drugs and innovative pain management approaches, with a strong emphasis on patient outcomes and quality of life.
