Abstract:Objective：To analyze the application effect of multi-channel information transmission system based on 5G network combined with POCT in shortening the door to balloon time of acute STEMI patients. Methods：Fifty STEMI patients admitted to Binzhou Medical University Hospital for routine ambulance admission and PCI treatment from January 2020 to October 2021 were selected as the control group. From November 2021 to December 2022，the multi-channel information transmission system based on 5G network combined with POCT was used as the experimental group for 50 patients admitted to hospital for PCI after ambulance treatment. The time of FMC- diagnosis，emergency department detention time，D-to-B time，success rate of treatment and mortality，incidence of disease complications before and after PCI，length of hospital stay and hospitalization cost were observed and recorded. Results：FMC-diagnosis time（5.96±2.258），emergency department detention time（13.70±24.203）and D-to-B time（41.64±26.242）in experimental group were less than those in control group（9.04±3.226，37.20±24.502，73.34±35.832，respectively）. The difference was statistically significant（P < 0.001）. The incidence of postoperative complications in the experimental group（22%）was lower than that in the control group（44%），and the length of hospital stay and hospitalization cost in the experimental group were lower than that in the control group，with statistical significance（P < 0.05）. There was no significant difference in the incidence of complications，success rate of treatment and mortality between the two groups before PCI（P > 0.05）. Conclusion：5G network multi-channel information transmission system combined with POCT can shorten the treatment time of acute STEMI patients，reduce the incidence of complications after PCI，shorten the hospital stay and reduce the hospitalization cost.
