Chlorhexidine: Patient Bathing and Infection Prevention

Area of Science:

• Infection Prevention and Control
• Antimicrobial Resistance
• Public Health

Background:

• Healthcare-associated infections (HAIs) significantly contribute to patient morbidity and mortality in the USA.
• HAIs result in substantial annual increases in healthcare expenditures.
• Many HAIs are preventable, making their eradication a national health priority.

Purpose of the Study:

• To evaluate the role of chlorhexidine (CHG) bathing in preventing HAIs.
• To address concerns regarding emerging microorganism resistance due to increased CHG use.
• To highlight the need for improved guidelines on CHG bathing protocols.

Main Methods:

• Review of current practices and literature on chlorhexidine (CHG) bathing for HAI prevention.
• Analysis of potential risks associated with widespread CHG use, including antimicrobial resistance.
• Assessment of compliance monitoring for CHG bathing protocols.

Main Results:

• Chlorhexidine (CHG) bathing has shown beneficial results in preventing HAIs when used alone or in bundles.
• Increased use of CHG for skin antisepsis raises concerns about the selection of CHG-tolerant microorganisms.
• Routine monitoring of CHG bathing compliance is often lacking.

Conclusions:

• A "one-size-fits-all" approach to infection prevention may inadvertently promote CHG resistance.
• Further studies are essential to understand the long-term impact of CHG bathing on HAI prevention.
• Development of more robust guidelines is necessary to optimize the use of CHG and mitigate resistance risks.
