Summary

Triple lumen catheters (TLC) showed a higher incidence of catheter tip infections compared to single lumen catheters (SLC). This suggests increased utilization of TLCs may contribute to higher infection risks in patients.

Area of Science:

  • Medical Microbiology
  • Infectious Diseases
  • Healthcare Epidemiology

Background:

  • Subclavian catheters are critical for patient care but pose infection risks.
  • Distinguishing infection rates between single lumen catheters (SLC) and triple lumen catheters (TLC) is important for patient safety.
  • Previous studies have not conclusively determined if catheter lumen number impacts infection incidence.

Purpose of the Study:

  • To compare the catheter tip infection rates between single lumen catheters (SLC) and triple lumen catheters (TLC).
  • To investigate the relationship between catheter type and site of infection.
  • To evaluate the impact of multiple injection ports on catheter-related infections.

Main Methods:

  • Retrospective study of 481 patients from October 1983 to September 1985.
  • Analysis of 496 subclavian catheter insertions (252 SLC, 244 TLC).
  • Review of catheter-related problems recorded by the hospital's IV Team, focusing on catheter tip and insertion site infections.

Main Results:

  • Catheter tip infection incidence was 1.6% for SLC (4/248) versus 4.9% for TLC (12/232), with a p-value of 0.065.
  • No significant difference in insertion site infection rates between TLC (1/243) and SLC (1/251).
  • A trend towards higher catheter tip infections with TLC was observed.

Conclusions:

  • The increased utilization of triple lumen catheters (TLC) due to multiple injection ports may be associated with a higher risk of catheter tip infections.
  • Further research is warranted to confirm the association between TLC use and increased infection rates.
  • Optimizing catheter care protocols for TLC may be necessary to mitigate infection risks.
