Abstract:

Objective The aim is to establish an expert consensus（hereinafter referred to as "Consensus"）on safety management of transfusion connection and port protection devices for vascular access，to prevent catheter related bloodstream infection and provide patients with safe，effective and standardized intravenous therapy. Methods Using evidence-based methods，according to the level of evidence，the evidence in this field was searched，evaluated and summarized，and relevant recommendations and research conclusions were extracted，and then the first draft of consensus was formed. Through a round of Delphi expert consultation and 2 rounds of expert meetings，opinions from domestic experts in many fields and disciplines were sought and integrated；the content was adjusted and the consensus was reached. Results The positive coefficient is 100%；the authoritative coefficient is 0.92；the average value of each index is more than 4；the coefficient of variation is less than 0.22. The Kendall’s harmony coefficient of the expert’s opinion is 0.35（ χ²=144.44，P<0.001）. A consensus recommendation on the classification and maintenance of infusion connection devices was reached. Conclusion The Consensus is scientific，which can provide a reference for the safety management of transfusion connection and port protection devices in China，and provide a basis for clinical decision-making to prevent catheter related bloodstream infection.
