L’hygiène des mains reste à la fois la principale stratégie et un défi permanent pour le contrôle des infections. Les principaux problèmes liés à la durabilité du suivi automatique de l’hygiène des mains sont les taux de rotation du personnel de santé et le déclin de la participation. Dans cette étude, nous avons eu l’occasion d’observer le respect de l’hygiène des mains pendant trois ans, avec l’intervention d’un système de rappel en temps réel. Notre objectif était d’évaluer le respect de l’hygiène des mains et l’impact des rappels en temps réel.
Introduction 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. In this study we had the opportunity to observe hand hygiene compliance over three years, with the intervention of a real-time reminder system. We aimed to assess hand hygiene compliance and the impact of real-time reminders. Methods We observed HCWs and room compliance with using alcohol-based hand rubs (AHR) on room entry and exit. Linear multilevel 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). Results 111 HCWs were observed and 525,576 activities were identified in the database. We observed 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. In this study 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.
