The Effect of Immediate Versus Delayed Port Access on 30-Day Infection Rate

Area of Science:

• Medical Devices
• Infection Control
• Interventional Radiology

Background:

• Chest ports are crucial for long-term therapies.
• Standardizing port access protocols is essential for patient safety.
• Previous data on immediate access infection risk is limited.

Purpose of the Study:

• To compare the 30-day infection risk between immediate and delayed chest port access.
• To provide evidence for developing safer port access guidelines.
• To analyze a substantial dataset for robust statistical power.

Main Methods:

• Retrospective chart review of 3322 chest port placements.
• Data collected on initial access time, 30-day infection events, and causative organisms.
• Analysis of infection rates based on timing of first access and device type.

Main Results:

• Overall 30-day infection rate was 1.93% (64/3322 ports).
• Immediate access ports showed a higher infection rate (3.17%) compared to delayed access ports (1.43%; P < .005).
• Dual lumen devices had a significantly higher infection rate than single lumen devices (P = .006).

Conclusions:

• Immediate chest port access is associated with a statistically significant higher infection rate.
• Deferring initial port access beyond 24 hours reduces infection risk.
• Findings support the development of guidelines recommending delayed initial port access.
