Peripheral venous catheters: an under-evaluated problem.

Area of Science:

• Medical Devices
• Infectious Diseases
• Healthcare Epidemiology

Background:

• Peripheral venous catheters (PVCs) are ubiquitous in hospitals, used by up to 70% of patients.
• PVC utilization accounts for a significant portion of patient days in acute care settings (15-20%).
• Existing research primarily addresses thrombophlebitis, with limited consensus on optimal catheter change protocols.

Purpose of the Study:

• To highlight the understudied issue of PVC-associated bloodstream infections (PVC-BSIs).
• To evaluate the current understanding and reported incidence of PVC-BSIs.
• To underscore the need for further research into PVC-BSI dimensions and control measures.

Main Methods:

• Review of existing literature on peripheral venous catheter complications.
• Analysis of reported incidence rates for PVC-associated bloodstream infections (PVC-BSIs).
• Comparison of PVC-BSI data with other catheter-associated infections.

Main Results:

• While often considered rare, some studies report PVC-BSI numbers comparable to central line-associated infections.
• Reported incidence density rates for PVC-BSIs range from 0.2-0.7 episodes per 1000 device days.
• Data on PVC-BSIs are limited, and results from thrombophlebitis studies require cautious interpretation.

Conclusions:

• The clinical significance of PVC-BSIs remains uncertain, with conflicting data on their frequency and impact.
• There is a critical need for large-scale, multicentre trials to accurately determine the burden of PVC-BSIs.
• Further research is essential to develop effective strategies for preventing and managing PVC-BSIs.
