Implementing a Compliance Monitoring Process to Promote Chlorhexidine Gluconate Bathing and Hand Hygiene: An Initiative to Decrease Central Line–Associated Bloodstream Infections

Abstract

Chlorhexidine gluconate (CHG) bathing has proven to reduce central line–associated bloodstream infections (CLABSI) in hospitalized patients. The aim of this study is to evaluate whether the implementation of a compliance monitoring process for CHG bathing and strict hand hygiene as part of the traditional CLABSI prevention bundle will reduce the overall hospital CLABSI standardized infection ratio (SIR). A quasi-experimental study was conducted in intensive care and non-intensive care inpatient hospital units in an urban 361-bed teaching hospital in Western Pennsylvania. The pre-intervention period consisted of January–August 2021, the intervention period consisted of September–November 2021, and the post-intervention and sustainability period consisted of December 2021–June 2022. A compliance monitoring process for the initiation of a daily bath using a 4% CHG solution and strict hand hygiene surveillance was implemented as part of the standard CLABSI prevention bundle (which includes standardized insertion checklists and processes, daily necessity assessment, dressing change and integrity standards, five moments hand hygiene standards, CHG disk [Biopatch], end caps [Curos], and care of tubing). A statistically significant increase in hand hygiene (p=<0.001) and in CHG bathing compliance (p=0.014) helped reduce the overall hospital CLABSI SIR from 1.45 to 0.82, standing for an overall 43.4% decrease. Cost reduction was statistically significant (p=0.011) and was an estimated $1.4 million dollars in savings for the hospital. Incorporate the compliance monitoring component for CHG bathing and hand hygiene as part of the best strategy for CLABSI bundle prevention within the healthcare system.
