Advancing Antimicrobial Stewardship in Outpatient Dialysis Centers Using the Positive Deviance Process

Abstract

Antimicrobial resistance is a major growing problem fueled by inappropriate use of antimicrobials. Patients requiring maintenance hemodialysis are at especially high risk for infections caused by antimicrobial-resistant bacteria. The Centers for Disease Control and Prevention has recommended development and implementation of antimicrobial stewardship programs to combat the spread of resistant pathogens. This article describes in detail a multifaceted antimicrobial stewardship intervention that featured staff education and a behavioral change process, Positive Deviance, and its implementation in six outpatient hemodialysis units. Results of the intervention demonstrated a 6% month-to-month reduction in antimicrobial doses/100 patient months over the course of the 12 months intervention, with a decrease in mean antimicrobial doses from 22.6/100 to 10.5/100 patient months from the beginning to the end of the intervention period. These results demonstrate the effectiveness of this multifaceted intervention in engaging staff and improving antimicrobial prescribing patterns.
