New Technologies To Prevent Healthcare-Associated Infections

New technologies for the prevention of healthcare-associated infections are increasingly developed and marketed to healthcare centers globally. New Technologies for Improvement of Cleaning Monitoring

  • (ATP) levels and fluorescent markers are used as surrogates of contamination to assist in monitoring of cleaning. ATP levels represent the organic load of a surface. Fluorescent markers are placed on surfaces before cleaning, then reassessed with black light for their persistence, manual cleaning should remove these markers.

  • However, there is controversy on which could be the objective monitoring method, ATP versus fluorescent markers, is the better representative of microbial contamination.

New Technologies by Room Cleaning Robots

  • Bypassing the variability in human practices, disinfection devices are at present deployed after manual cleaning to further lower the bioburden inpatient rooms.

  • These devices include hydrogen peroxide (HP) or UV-light emitting machines. Always, manual cleaning remains an important step, as gross organic soil should be removed from surfaces to let the penetration of germicidal vapor/aerosol or radiation in.

  • The UV light or HP is toxic to humans. Hence, these devices are used only in empty patient rooms – for example, after a patient discharge.

Hand Hygiene Monitoring New Technologies

  • Hand hygiene is the main infection prevention strategy that is simple to do, but healthcare worker compliance is often low. Research says, that the estimated wide range of compliance, is roughly 40% as per WHO

  • Traditional monitoring has been direct observation; still this is limited by high resource requirements and the Hawthorne Effect.

  • Technologies are developed with a wide range of capabilities, from monitoring product usage as an estimate of hand hygiene events, to entierly automated systems which can track healthcare worker movements and product dispensation events.

  • The automated monitoring systems are capable of detecting hand hygiene events as healthcare workers enter and exit patient areas, and may monitor all 5 of the WHO’s Moments of Hand Hygiene.
