CVC, central venous catheter; PICC, peripherally inserted central catheter; ICU, intensive care unit; CoNS, coagulase-negative staphylococci. The data in the table presented refer to the prevalence of isolated organisms from CVCs. “N” refers to the total number of cultured catheters in different wards. If there were no isolated organisms after microbial culture, “—” is filled in the spaces. There were significant differences in isolated organisms on catheter surface from different wards (X2 = 124.046, ).
