Objective　To develop the patient safety smart warning system based on 5G internet of things technology, and

to explore its application effect in the Plastic and Reconstructive Surgery nursing. Methods　The patient safety smart warning

system was constructed based on research group establishing, literature research and Delphi study, then patient safety warning

indicators were screened and modules were built. Based on 5G network, the patient safety indicators and the connected equipment involved were integrated with the system. Then the system was applied in plastic and reconstructive surgery ward after staff

training. Two months before and after the application of the system, the postoperative complications, incidence of adverse events

and discovery rate of potential complications in patients were calculated, and graded care quality was scored. Medical staff’s

application satisfaction was investigated using self-designed questionnaire. Results　After the application of the patient safety

smart warning system, the discovery rate of potential complications in patients was increased significantly (P<0.05). The incidence of postoperative complications and adverse events decreased with no significant difference (P>0.05). The score of graded

care quality improved from 97 to 99 after the application of the system. The overall satisfaction score of medical staff to patient

safety smart warning system was 4.59±0.49. Conclusion　Application of the patient safety smart warning system based on 5G

Internet of things technology can improve the discovery rate of potential complications in patients, enhance the predictability of
