The monitoring of hand hygiene activities can effectively reduce infection and contamination in the Intensive Care Unit (ICU). In this paper, we created a clinical dataset using CCTV cameras installed in ICU to explore the feasibility of recognizing the hand-washing steps of clinicians. A video processing architecture including hand landmark detection and classification is presented. Such a system can potentially be used to alarm clinicians to follow the guidelines of hand hygiene. The experimental results show that the average accuracy of our methodology can achieve 95% under the personalized model and 56% under the generalized model. The preliminary results suggest that hand hygiene is subject-dependent, which is related to individuals’ palm size and washing habits. The cross-subject modeling or subject-adaptive learning can be applied to further improve the accuracy of recognition towards a more generalized solution. The insights of the study are helpful for designing a hand hygiene scoring and alarming system as a part of hospital IoT. The hospital data and code are available at https://github.com/SunnySideUp11/Hand-Hygiene-ICU.
