Mapping Knowledge Domains of Diabetic Pressure Injuries: A 25-Year Bibliometric and Visualization Analysis

Patients with diabetes are more susceptible to Pressure Injuries (PIs) due to chronic hyperglycemia, neuropathy, microvascular dysfunction, and immune impairment, which contribute to delayed and complex wound healing.This study systematically analyzes research trends, hotspots, and international collaboration patterns in the field of diabetic PIs using bibliometric methods.A total of 410 English-language publications were retrieved from the Web of Science Core Collection through December 5, 2024.CiteSpace, VOSviewer, R, and Bibliometric.comwere employed to visualize publication trends, institutional and national distributions, author collaboration networks, high-frequency keywords, and co-citation patterns.Results show a significant increase in publications since 2018, with the United States leading in output and international collaboration, particularly with China and the United Kingdom.Research hotspots primarily focus on "pressure ulcers," "diabetic foot ulcers," "risk factors," and "wound healing."Cluster and burst keyword analyses revealed three major themes: chronic wound types, pathogenesis and epidemiology, and therapeutic strategies.Emerging research topics include biomaterials, critical care, and predictive modeling.This bibliometric study provides a comprehensive overview of the field, highlights influential contributors, and offers insights into evolving research priorities and future directions.
