Abstract

OBJECTIVE:

To demonstrate whether daily bathing with cloths impregnated with 2% chlorhexidine gluconate will decrease colonization of resistant bacteria and reduce the rates of health care-associated infections in critically injured patients.

DESIGN:

Retrospective analysis of data collected 6 months before and after institution of a chlorhexidine bathing protocol.

SETTING:

A 12-bed intensive care unit in a level I trauma center.

PATIENTS:

Two hundred eighty-six severely injured patients underwent daily chlorhexidine bathing during the 6-month intervention; 253 patients were bathed without chlorhexidine prior to the intervention.

INTERVENTIONS:

Daily chlorhexidine bathing.

MAIN OUTCOMES MEASURES:

Rates of ventilator-associated pneumonia (VAP), bloodstream infection, and colonization with resistant organisms (methicillin-resistant Staphylococcus aureus [MRSA] or Acinetobacter species).

RESULTS:

Baseline patient and injury characteristics were similar between cohorts. Patients receiving chlorhexidine baths were significantly less likely to acquire a catheter-related bloodstream infection than comparators (2.1 vs 8.4 infections per 1000 catheter-days, P = .01). The incidence of VAP was not affected by chlorhexidine baths (16.9 vs 21.6 infections per 1000 ventilator-days in those with vs those without chlorhexidine baths, respectively, P = .30). However, patients who received chlorhexidine baths were less likely to develop MRSA VAP (1.6 vs 5.7 infections per 1000 ventilator-days, P = .03). The rate of colonization with MRSA (23.3 vs 69.3 per 1000 patient-days, P < .001) and Acinetobacter (1.0 vs 4.6 per 1000 patient-days, P = .36) was significantly lower in the chlorhexidine group than in the comparison group.

CONCLUSIONS:

Daily bathing of trauma patients with cloths impregnated with 2% chlorhexidine gluconate is associated with a decreased rate of colonization by MRSA and Acinetobacter and lower rates of catheter-related bloodstream infection and MRSA VAP.
