Abstract: Objective We conducted co-word analysis on transfusion-related adverse events in foreign literature to form a visualization map, and analyzed research hotspots and found out risks. Methods A total of 765 foreign literature studies on transfusion-related adverse events were statistically analyzed, and statistical analysis tools and knowledge visualization software used for literature bibliographic information were imported for research. Results Research in blood transfusion focused on four major areas, including haemovigilance, transfusion reactions, infection prevention and control, and complications. Conclusion Transfusion reaction, viral infections and other complications are still the current hotspots. It is necessary to establish a blood early warning system in China.

Key words: Haemovigilance Adverse events, Visualization, Risk management
