Adhesive tape and intravascular-catheter-associated infections.

Adhesive tape is placed in close contact with intravascular catheters for extended periods and could theoretically contribute to local infections. We found that 74% of specimens of tape collected in one hospital were colonized by pathogenic bacteria. However, only 5% of specimens had significant growth from an inner layer obtained by discarding the outside layer from each roll. We suggest that adhesive tape is a potential source of pathogenic bacteria and that discarding the outer layer from a partially used roll might be a simple method for reducing the risk of infection to patients.
