Education of Physicians-in-Training Can Decrease the Risk for Vascular Catheter Infection

Background:

Procedure instruction for physicians-in-training is usually nonstandardized. The authors observed that during insertion of central venous catheters (CVCs), few physicians used full-size sterile drapes (an intervention proven to reduce the risk for CVC-related infection).

Objective:

To improve standardization of infection control practices and techniques during invasive procedures.

Design:

Nonrandomized pre-post observational trial.

Setting:

Six intensive care units and one step-down unit at Wake Forest University Baptist Medical Center, Winston-Salem, North Carolina.

Participants:

Third-year medical students and physicians completing their first postgraduate year.

Intervention:

A 1-day course on infection control practices and procedures given in June 1996 and June 1997.

Measurements:

Surveys assessing physician attitudes toward use of sterile techniques during insertion of CVCs were administered during the baseline year and just before, immediately after, and 6 months after the first course. Preintervention and postintervention use of full-size sterile drapes was measured, and surveillance for vascular catheter-related infection was performed.

Results:

The perceived need for full-size sterile drapes was 22% in the year before the course and 73% 6 months after the course (P < 0.001). The perceived need for small sterile towels at the insertion site decreased reciprocally (_P_ < 0.001). Documented use of full-size sterile drapes increased from 44% to 65% (_P_ < 0.001). The rate of catheter-related infection decreased from 4.51 infections per 1000 patient-days before the first course to 2.92 infections per 1000 patient-days 18 months after the first course (average decrease, 3.23 infections per 1000 patient-days; _P_ < 0.01). The estimated cost savings of this 28% decrease was at least 63000andmayhaveexceeded63 000 and may have exceeded 63000andmayhaveexceeded800 000.

Conclusions:

Standardization of infection control practices through a course is a cost-effective way to decrease related adverse outcomes. If these findings can be reproduced, this approach may serve as a model for physicians-in-training.
