Scrubbing technique for needleless connectors to minimize contamination risk.

This study aimed to investigate the appropriate scrubbing technique for needleless connectors to minimize contamination risk. To demonstrate a highly effective scrubbing technique to physically eliminate bacteria, needleless connectors were contaminated with Geobacillus stearothermophilus spores and then scrubbed. The study showed that the highest bacterial elimination rate was achieved by scrubbing an access port in a straight line with an alcohol cotton swab, applying a force that was almost equal to an arterial compression haemostasis to the access port, and repeating this procedure once using a new alcohol cotton swab.
