Sensor-Based Monitoring of Hand Hygiene in Hospitals: Strengths and Weaknesses of an IoT-Based System

Hand hygiene is a critical aspect of patient safety in hospitals. To assess adherence to hand hygiene protocols, a sensor-based system has been developed that monitors the movements of healthcare professionals using Bluetooth technology. This system comprises a Data Collection Node (DCN) and several Bluetooth beacons strategically installed within the monitored department. Results from a study conducted at the Eastern Switzerland Children's Hospital indicate that while the system is capable of generating movement profiles, it fails to provide reliable adherence profiles for hand hygiene. It is essential to develop more precise technologies, which may be more costly than the Bluetooth beacon technology currently employed. Nevertheless, this project highlights potential avenues for enhancing hospital hygiene practices through digital monitoring and support.
