Up to 90% of catheters fail before therapy is complete. Improved dwell time of intravenous catheters for even small increments of time would further reduce the number of insertions, staff workloads, and costs. In this study, the investigators investigated whether short peripheral venous catheter site of insertion influence the dwell time.

Inclusion Criteria:

• Age >18 years
• Expected duration of infusion therapy by short peripheral intravenous catheters >7 days
• Give written informed consent

Exclusion Criteria:

• The peripheral venous catheter was inserted in emergency room or in emergency circumstances
• Bloodstream infection
• Had a peripheral venous catheter already in situ at the baseline
• Altered mental state
