Objectives: Chlorhexidine gluconate (CHG)-coated gel pad dressings for central venous catheter (CVC) may prevent CVC-related bloodstream infections (CRBSI). However, real-world data showing beneficial effects in patients with hematologic malignancies are scarce.
Methods: In a matched-pair analysis with data from a multicenter CVC registry, non-tunneled jugular and subclavian vein CVC in adults with hematologic malignancies or germ cell tumors (including patients receiving autologous hematopoietic stem cell transplantation ) with CHG were compared with non-CHG dressings. The primary endpoint was definite CRBSI rate within 14 days (dCRBSI14) of CVC insertion; secondary endpoints were combined rate of definite or probable CRBSI within 14 days (dpCRBSI14), overall (dpCRBSI), and CRBSI incidences of all estimates.
Results: In total, 2070 CVCs were assessed. There was no statistically significant difference in dCRBSI14 (2.3% vs. 3.5%) between patients with and without CHG gel dressings. Likewise, with regards to dpCRBSI14 (6.2% vs. 6.3%) and the overall dpCRBSI rate (9.2% vs. 10.5%), no significant difference was detected. Furthermore, dCRBSI14 incidence (2.0 vs. 3.2/1000 CVC days), dpCRBSI14 incidence (5.4 vs. 5.6/1000 CVC days), and overall CRBSI incidence (5.5 vs. 6.0/1000 CVC days) showed no significant differences.
Conclusions: CRBSI rates were not reduced by the use of CHG gel dressings in patients with hematologic malignancies and/or ASCT.Reference:
