Impact of environmental hygiene interventions on healthcare-associated infections and patient colonization: a systematic review

Key Points

Environmental hygiene interventions significantly reduce healthcare-associated infections and colonization rates.
Among 635 records, 8 studies, including 3 RCTs, showed substantial decreases in MRSA and C. difficile rates.
This systematic review adhered to PRISMA guidelines, investigating interventions like UV light and copper surfaces in healthcare settings.
Findings highlight the effectiveness of hygiene strategies, but emphasize the need for standardized multicenter RCTs to enhance evidence.

Abstract

Background: Healthcare-associated infections (HAIs) are an important concern in medical settings, as they can increase patient morbidity and mortality, prolong hospital stays, and escalate healthcare costs. Environmental hygiene and cleaning play a crucial role in controlling these infections, particularly in avoiding the spread of multidrug-resistant organisms (MDROs).Aim: To investigate the effect of environmental hygiene interventions on HAIs most studies were high quality but lacked true controls. Conclusion: Environmental hygiene interventions effectively reduce HAIs and colonization, particularly for environmentally persistent pathogens like VRE. However, study variability underscores the need for standardized, multicenter RCTs to strengthen evidence and guide infection control policies.
