Meticulous catheter care and aseptic approach reduce catheter-related bloodstream infections significantly in hemodialysis patients: A 5-year single center study

Abstract

Aim: The use of central venous catheters as hemodialysis vascular access is a major contributor to high bloodstream infection rate. In our dialysis unit in Shenzhen Guangdong Province China, we have developed and used our own dialysis catheter care protocol since May 2013 with good results. In this study, we would like to share our experience with the other units. Methods: We have undertaken a 5-year retrospective analysis to determine our tunneled dialysis catheter-related blood stream infection rate by adding the number of infections divided by total number of catheter days × 1000. The results were compared with another study carried out in Henan Province China. Demographic data were summarized using descriptive statistics. Continuous and categorical variables were compared using t-test and χ2 test respectively. Results: Between 2017 and 2021, a total of 216 tunneled dialysis catheters were managed by following our own dialysis access pathway and catheter care protocol. The tunneled dialysis catheter-related bloodstream infection rate was 0.0229 per 1000 catheter days in the 5-year period. Conclusion: Comparing with other published studies in China, our unit has achieved a very low rate of tunneled dialysis catheter-related bloodstream infection which has been sustained over time. This paper explores how our protocol and implementation might have contributed to the results.
