We proposed to perform a prospective randomized controlled trial to study the effect of the use of a commercially-available chlorhexidine-impregnated sponge (Biopatch) as part of central venous catheter care on catheter-related bloodstream infections among patients in two Barnes-Jewish Hospital ICUs.

Condition Intervention Phase
Catheter-related Bloodstream Infection Device: Chlorhexidine-impregnated foam dressing Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment

Primary Outcome Measures:
  • The Number of Catheter Related Bloodstream Infections (BSI) /1000 Catheter Days in Both Arms [ Time Frame: 2 years ]
    The outcome measure is the number of episodes of bloodstream infections (BSI) divided by the catheter days at risk multiplied by 1000 for standardization

Secondary Outcome Measures:
  • Clinical Sepsis Episodes/Per 1000 Catheter Days [ Time Frame: 2 years ]
    This measure is a combination of patients with positive blood cultures (BSI) and patients who had signs and symptoms of sepsis but with negative blood cultures. These patients still required treatment with antibiotics.

Enrollment: 1088
Study Start Date: February 2006
Study Completion Date: May 2009
Primary Completion Date: February 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: 1
Patients in this arm will continue to get routine care
Experimental: Chlorhexidine-impregnated foam dressing
Patient's catheters were cleaned with chlorhexidine-alcohol solution at least weekly before application of the Biopatch. These were evaluated daily and if the dressing was bloody, soiled or damaged, the dressing and the Biopatch were replaced prior to the 7-day period.
Device: Chlorhexidine-impregnated foam dressing
Patients in the treatment arm will have the Biopatch incorporated into their catheter care protocol. ICU nurses were instructed on the proper use of this novel dressing/sponge. Catheter dressing changes will only be done every 7 days unless there is visible blood, soiling underneath the dressing, or if the dressing comes off.
Other Name: Biopatch Antimicrobial Dressing

Detailed Description:
At the time of the inception of this study, there were no published randomized controlled trial on the efficacy of the Biopatch in reducing bloodstream infections. Preliminary data has shown that the Biopatch decreases colonization of the catheter exit site and thereby decrease bloodstream infections but this was at that time only theoretical.
