Study Purpose

To determine whether cover gowns in addition to gloves decrease the nosocomial transmission of vancomycin-resistant enterococci (VRE) in an intensive care unit.

Intervention Characteristics/Basic Study Process

  • Current practice studied first: gown and nonsterile, disposable gloves. Change in practice studied: gloves only.
  • Private rooms and hand washing signs
  • Equipment, such as blood pressure cuffs, thermometers, and stethoscope, dedicated to the patient

Sample Characteristics

  • Mean patient age was 54.6 years (SD = 16.2).
  • Patients with at least two perirectal cultures
  • For the gown and gloves study period, 141 patients (with 64 patients colonized on admission) were enrolled for 895 days.
  • For the gloves only group, mean age was 55 years (SD = 15.1), and 173 patients (with 71 colonized) were enrolled for 945 days.

Setting

Medical intensive care unit (teaching hospital)

Study Design

This was a prospective study.

Results

Gown and Gloves

  • 22% (11 of 49) of patients at risk developed VRE
  • Acquisition rate: 1.80 cases per 100 days
  • 23% of patients’ admission cultures grew VRE

Gloves Only

  • 22% (21 of 51) of patients at risk developed VRE
  • Acquisition rate: 3.78 cases per 100 days
  • 20% of patients' admission cultures grew VRE

Limitations

  • Length of stay was a risk factor.
  • No conceptual model was described.
