Effects of clinically‐indicated replacement vs routine change of peripheral intravenous catheters

Catheter‐related blood stream infection · any patient requiring a PIVC expected to remain in‐situ for at least 3 days

Effects of clinically‐indicated replacement showed no clear difference in catheter‐related blood stream infection (during hospitalisation) compared with routine change of peripheral intravenous catheters (low certainty).

Effects of clinically‐indicated replacement vs routine change of peripheral intravenous catheters

Infiltration (during hospitalisation) · any patient requiring a PIVC expected to remain in‐situ for at least 3 days

Effects of clinically‐indicated replacement probably leads to higher infiltration (during hospitalisation) compared with routine change of peripheral intravenous catheters (moderate certainty).
