Objective: This study aimed to assess the effectiveness of chlorhexidine-impregnated dressing in a bundle of interventions to reduce the rate of central line-associated bloodstream infections (CLABSIs).
Materials and methods: We performed a bundle of interventions to reduce the CLABSIs from 2012. As one bundle component, we started using the chlorhexidine impregnated catheter dressing. We used a document describing applying central venous catheters for the practicing physicians and nurses, and we organized several educational meetings. An interrupted time-series analysis was performed.
Results: Seventy-six CLABSI events were detected in total between January 1, 2011, and December 31, 2019. Twenty-six cases were detected in the pre-intervention period (January 1, 2011, to December 31, 2011), and 50 patients were seen in the post-intervention term (January 1, 2012, to December 31, 2019). The annual CLABSI rate was 2.60/1000 catheter days in the pre-intervention period and 0.46/1000 catheter days (p=0.0328) in the post-intervention period. The CLABSI rate among hematology-oncology inpatients decreased from 3.39 to 0.71 (p=0.0101) in the same term.
Conclusion: By using bundle form including chlorhexidine impregnated dressing, the rate of CLABSIs decreased significantly. This effect has been observed consistently for nine years, and the clinical pathway use has become the standard care protocol.
