Objective To formulate an expert consensus on technical specifications for arteriovenous fistula puncture using fistula soft catheter needles(hereinafter referred to as the “Consensus”),providing references for standardizing the operation methods of fistula soft catheter needles for internal fistulas. Methods Domestic and international literature on arteriovenous fistula puncture using fistula soft catheter needles was reviewed,combined with the work experience of blood purification experts. Based on evidence-based nursing,the best evidence was identified,and expert consultation forms were designed. Through 2 rounds of Delphi expert consultation and expert panel discussions,the content of the consensus was adjusted and revised. Results A total of 17 experts were invited to participate in the consultation. All 17 questionnaires were eventually returned,achieving a 100% response rate. All experts provided suggestions on relevant issues during the consultation process. The coordination coefficients for the first and second rounds of expert consultations were 0.507 and 0.524,respectively,both of which were statistically significant. Additionally,the expert authority coefficient was 0.99,indicating a high level of authority in the expert consultation and credible results. The coefficient of variation for both the first and second rounds is less than 0.15,indicating that the expert’s judgment results are relatively consistent. The Consensus summarizes 10 main topics related to the terminology and definitions,scope of application and contraindications,personnel qualifications and training,pre-puncture preparation,pre-puncture evaluation,puncture implementation,puncture needle fixation,needle removal,operational precautions,and material handling of internal fistula soft needle puncture. Conclusion The Consensus has strong practicality and scientific validity,providing clinical operation practices and teaching guidance for the puncture operation technology of arteriovenous fistulas using fistula soft catheter needles,thereby promoting the standardized development of this technology.
