Inadequate catheter securement is an underrecognized patient safety issue that contributes significantly to catheter-related complications, including dislodgment, occlusion, infiltration, and infection. Pooled data from prospective product trials at 83 hospitals compared tape to a standard peripheral intravenous (PIV) securement method with a PIV-specific catheter-stabilizing device (StatLock). A 67% reduction (P<.001) ...
