Abstract：Objective To evaluate the application value of the third-party witness model in the informed consent process for high-risk interventional procedures and to establish a standardized operational pathway.Methods A retrospective cohort study was conducted,involving 156 patients who underwent high-risk interventional procedures in the First People's Hospital of Lianyungang from August 2024 to August 2025.Participants were divided into a third-party witness group(n=78)and a conventional control group(n=78).The incidence of medical disputes,completeness of informed consent documentation,patient understanding,and satisfaction scores were compared between the two groups.Results The incidence of medical disputes in the witness group was 1.28%(1/78),significantly lower than that in the control group(11.54%,9/78)(P<0.05).The completeness rate of informed consent documentation in the witness group(98.72%)was significantly higher than that in the control group(82.05%)(P<0.05).The understanding score of patients'families in the witness group(4.65±0.48)was significantly higher than that in the control group(3.82±0.76)(P<0.05).Conclusion The third-party witness mechanism can effectively improve the quality of informed consent,and mitigate medical disputes.The standardization pathway established in this study holds significant clinical promotion value.
