Objective This study aimed to explore a novel approach to intravenous infusion safety management utilizing QR code technology, by constructing a closed-loop management mode and validating its practical application value in the clinical setting of the gastroenterology department. Methods Employing a quasi-experimental design, 160 patients requiring long-term intravenous infusion (duration ≥5 days) admitted to the gastroenterology department of our hospital from July to December 2025 were enrolled. The patients were divided into two groups: 80 patients in the control group received routine infusion management, while 80 patients in the observation group underwent the QR code-based closed-loop management mode. Comparisons were made between the two groups regarding the incidence of infusion-related adverse events (including errors, infiltration/extravasation, and phlebitis), nurses' compliance with standardized infusion rounds, timeliness of post-infusion handling, and patient satisfaction. Results The total incidence of infusion-related adverse events in the observation group was 3.75%, significantly lower than that in the control group (13.75%). The observation group also demonstrated significantly higher rates of nurses' compliance with standardized infusion rounds (96.25% vs. 81.25%), timeliness of post-infusion handling (98.75% vs. 85.00%), and patient satisfaction with infusion safety (93.75% vs. 80.00%). Conclusion The QR code-based closed-loop management mode for intravenous infusion enables precise, real-time monitoring and intervention throughout the entire infusion process. It effectively reduces infusion-related risks and enhances nursing quality and safety for patients in the gastroenterology department, demonstrating substantial clinical application value.
