Towards an antimicrobial 'microglove'

Area of Science:

• Microbiology
• Polymer Science
• Healthcare Infection Control

Background:

• Hospital-acquired infections are a significant concern, often spread through direct contact.
• Healthcare workers face challenges adhering to strict hand disinfection protocols.
• Effective infection prevention, particularly hand hygiene, is crucial in nosocomial settings.

Purpose of the Study:

• To develop an innovative hand rub with antimicrobial properties.
• To create a protective film on the hands, termed a "microglove," to improve hand hygiene.
• To enhance compliance with infection prevention measures in healthcare environments.

Main Methods:

• Formulation of co-polymers using Polyvinylpyrrolidone (PVP) and a branched C20 derivatized maleate (M20) at various ratios.
• Incorporation of the biocide benzalkonium chloride (BKC) into the co-polymer formulations.
• Evaluation of combined film-forming and antimicrobial activities using novel contamination and transmission assays.

Main Results:

• Several co-polymer formulations with BKC were tested for efficacy.
• A specific formulation demonstrated promising film-forming and antimicrobial properties.
• The optimal formulation consisted of 80% PVP and 20% M20 co-polymer with 0.9% BKC.

Conclusions:

• The developed antimicrobial microglove formulation meets the basic requirements for effective hand hygiene.
• This innovation offers a potential solution to improve healthcare worker compliance with hand disinfection.
• The microglove technology could significantly contribute to reducing the spread of infections in hospitals.
