Abstract:

Objective To comprehensively retrieve and analyze evidence related to clinical application of needle-free infusion connector,and summarize the best evidence. Methods The databases of evidenced based resources were searched by computer,including BMJ best practice,Uptodate,et al. In addition,complementary search of the comprehensive databases in both Chinese and English was conducted to collect literature including clinical decision support system,evidence summary,guideline,expert consensus from January 2014 to May 2019. 3 researchers evaluated the quality of the included literature independently. With the help of external experts and the standardized data extraction,eligible literature was selected for analysis. Results 13 pieces of evidence were included with 1 clinical decision support system,5 evidence summaries,5 guidelines,and 2 expert consensuses. A total of 36 recommendations were obtained and classified into 6 different aspects,namely policy recommendations,disinfection recommendations,flushing and sealing pipe,type of joint and its replacement,and cautions in use. Conclusion Health caregivers and other medical staff should regulate their behaviors based on the evidence of the needle-free infusion connector,develop policy specifications for the clinical application of needle-free infusion connector,refine its management and training content,optimize the clinical behavioral standards for the selection,replacement,disinfection,and sealing of needle-free infusion connector in practice to ensure patient safety.
