Abstract:

This prospective randomized controlled study with 975 non-tunneled central venous catheters (CVCs) showed that the semiquantitative roll-plate technique (SQC) was as accurate as the sonication method for diagnosis of catheter-related infections. Sonication is difficult to standardize whereas SQC is simpler, faster and as reliable as the sonication for culturing CVCs.
