Minimising Blood Stream Infection: Developing New Materials for Intravascular Catheters

Area of Science:

• Medical Devices
• Infectious Diseases
• Materials Science

Background:

• Catheter-related bloodstream infections (CRBSIs) pose a persistent threat to patients needing venous access, especially for long-term medication.
• While improved care bundles and aseptic techniques have reduced CRBSI rates, they remain unacceptably high, burdening patients and healthcare systems.

Purpose of the Study:

• To identify current issues affecting catheter performance.
• To critically evaluate design considerations for next-generation catheter systems.

Main Methods:

• Literature review focusing on catheter performance and emerging technologies.
• Analysis of design factors impacting infection rates and patient outcomes.

Main Results:

• Current catheter materials and designs present ongoing challenges in preventing infections.
• Advances in material science and engineering offer potential solutions for improved catheter safety and efficacy.

Conclusions:

• Despite progress, catheter-related infections necessitate continued innovation in catheter design.
• Future research should focus on novel materials and engineering approaches to mitigate infection risks and enhance patient care.
