Horizontal approaches to infection prevention: daily chlorhexidine gluconate bathing

Healthcare-associated infections (HAIs) pose a significant challenge in hospitals. Infection control strategies have been widely employed to mitigate their incidence. In hospitals, chlorhexidine gluconate (CHG) solutions are commonly used as antiseptic skin cleansers as part of comprehensive infection prevention bundles, with daily CHG bathing being highly effective in reducing HAIs and lowering skin micro-organism density. This evidence review addresses the challenges of risk stratification in implementing CHG bathing protocols in hospitals. It highlights the benefits of a horizontal approach, where CHG bathing is implemented across the entire facility rather than being limited to specific patient populations. Evidence from systematic reviews and studies suggests that CHG bathing consistently reduces HAI rates in both intensive care unit (ICU) and non-ICU settings, supporting the adoption of a hospital-wide approach. The findings emphasise the significance of incorporating CHG bathing as part of a comprehensive approach to infection prevention in hospitals and highlight the potential for cost savings.
