Summary: For hospitalized patients with peripheral intravenous (IV) catheters, a practice of waiting until clinically indicated to replace the IV catheter appears to be associated with the same risk of catheter-related bloodstream infection, local thrombophlebitis, or all-cause bloodstream infection, compared to a practice of routine IV catheter replacement every 72 to 96 hours.
