PP235 Topic: AS22–Quality and Safety/Errors/Data Management/Other: APPLICATION OF PDCA CYCLE IN RISK MANAGEMENT OF PERIPHERAL VENOUS INDWELLING NEEDLE OCCLUSION IN PEDIATRIC INPATIENTS

Aims & Objectives: To analyze the application effect of PDCA cycle in the risk management of peripheral venous catheter occlusion in hospitalized pediatric patients. Methods: A survey was conducted on 2663 pediatric patients admitted to our hospital using intravenous indwelling needles from July 2020 to July 2021 before the implementation of the project, and 2500 pediatric patients admitted to our hospital using intravenous indwelling needles from October 2021 to October 2022 after the implementation of the project. The PDCA cycle theory was applied to prevent the occurrence of tube blockage by establishing risk prevention and control, standardizing nursing operations, strengthening nursing staff training, and improving special quality control, Compare the blockage rate and duration of peripheral venous indwelling catheters in pediatric patients before and after the implementation of the PDCA cycle method, and evaluate the knowledge assessment scores of nurses in preventing blockage of indwelling catheters. Conduct on-site monitoring of the nurse's execution. Results: The incidence of indwelling needle blockage decreased from 20.09% before implementation to 9.09% after implementation. The average indwelling time of indwelling needles was (5.03 ± 2.54) days, which was higher than that before implementation (3.62 ± 1.49) days. The knowledge assessment scores and on-site monitoring of indwelling needle blockage among nurses before and after implementation were higher than those before implementation (P<0.05). Conclusions: The PDCA circulation theory has a significant anti blocking effect on intravenous indwelling needles in pediatric inpatients and can effectively prevent the occurrence of tube blockage during infusion.
