Three-year hand hygiene monitoring and impact of real-time reminders on compliance.

BACKGROUND: Hand hygiene remains both the major strategy and an ongoing challenge for infection control. The main issues in the sustainability of hand hygiene automatic monitoring are healthcare worker (HCW) turnover rates and declining participation. AIM: To assess hand hygiene compliance and the impact of real-time reminders over three years. METHODS: HCW compliance was observed for the use of alcohol-based hand rubs (AHR) on room entry and exit. Linear multi-level mixed models with time autocorrelations were performed to analyse the repeated measurements of daily room compliance and the effect of reminders over eight quarters (24 months). FINDINGS: In all, 111 HCWs were observed and 525,576 activities were identified in the database. There was an improvement in compliance both on room entry and exit over two years, and the rooms which had activated reminders had better performance than the rooms which did not have activated reminders. CONCLUSIONS: This study showed the benefit of using real-time reminders; even 20% of rooms with an activated reminder improved overall hand hygiene compliance. A randomized real-time reminder setting may be a potential solution in reducing user fatigue and enhancing HCW self-awareness.
