Skin antiseptics in healthcare facilities: is a targeted approach necessary?

Abstract

Background: Skin antisepsis occurs in every healthcare environment. From basic hand hygiene, to antiseptic bathing and pre surgical care with alcohol/chlorhexidine, use of antimicrobial agents to reduce the skin microflora has skyrocketed in the past several years. Although used in hopes of reducing the likelihood of infection in patients, many products have been identified as the source of infection in several outbreaks, sometimes due to the nonsterile nature of the many readily available antiseptics. BODY: Intrinsic contamination of antiseptics during the manufacturing process is common. In fact, since the majority of these products are sold as nonsterile, they are allowed some level of microbial contamination based on the United States Pharmacopeia documents 61 and 62. Unfortunately, sometimes this contamination is with microorganisms resistant to the antiseptic and/or with those pathogenic to humans. In this scenario, healthcare-associated infections may occur, leaving the patient at higher risk of mortality and increasing costs of care substantially. Although antibiotic stewardship programs throughout the world suggest targeting use of antibiotics to limit resistance, few healthcare environments include other antimicrobial agents (such as antiseptics) in their programs.

Conclusion: Due to the potential for contamination with pathogenic organisms and the increased likelihood of selecting for resistant organisms with widespread use of broad-spectrum agents with non-specific mechanisms of action, a discussion around including skin antiseptics in stewardship programs is necessary, particularly those labeled as nonsterile. At minimum, debating the pros and cons of targeting use of daily antiseptic bathing in hospitalized patients should occur. Through mindfully incorporating any antimicrobial agent, sterile or not, into our repertoire of anti-infectives, we can save patient lives, reduce infection, and save costs.
