A study published in Antimicrobial Resistance & Infection Control examined the effect of introducing an electronic hand hygiene surveillance and intervention system into an ICU. Researchers introduced the system into a general ICU at a tertiary care teaching hospital. The system leveraged radiofrequency transmitters in patient care areas placed on hand hygiene dispensers and individual personal bracelets. The transmitters, which were connected to a central computer, could detect entry and exit from patient areas as well as missed hand hygiene opportunities. Researchers also conducted 41 staff satisfaction questionnaires followed by validation of system accuracy. They compared electronic data to human observer data.
