Assessment of hand hygiene adherence using a web camera

A Pilot Study of Deep Learning Models for Camera based Hand Hygiene Monitoring in ICU

Hand hygiene is key to preventing cross-infections in the Intensive Care Unit (ICU). Monitoring of hand washing activities can effectively increase the compliance of clinicians to hand hygiene. In this paper, we explored the feasibility of recognizing clinicians' hand-washing activities using a clinical dataset recorded in ICU using CCTV cameras. We benchmarked three types of hand hygiene detection methods on the dataset with the aim of identifying the 7-step hand washing procedure defined by WHO. Experimental results show that our approach achieves 97% average accuracy for personalized and 67% for generalized modeling. Preliminary results indicate that hand hygiene recognition is subject-dependent, and thus cross-subject modeling or subject-adaptive learning should be used to enhance generalization. The feasibility and challenges of CCTV-camera-based hand hygiene recognition are discussed. The results may contribute to design a hand hygiene scoring and alert system as part of the IoT system in hospitals.

The use of digital technology to improve and monitor handwashing among children 12 years or younger in educational settings: a scoping review

Our scoping review aimed to identify and describe the application of digital technology in hand hygiene research among children in educational settings. We searched for articles in PubMed, IEEE Xplore, and Web of Science. Original hand hygiene research with a form of digital technology used among children ≤12 years in educational settings was eligible for inclusion. Twelve studies met the eligibility criteria and the data were extracted by two teams of independent co-authors for narrative synthesis. Ten studies used digital technology as an intervention tool and two for monitoring purposes. Three main digital technologies were identified including computer games (n = 2), videos (n = 8), and video cameras (n = 2). Digital technologies found in our scoping review were reported to be effective in hand hygiene studies over short temporal periods especially when used in combination with other measures. Future research may demonstrate the effectiveness of digital technology in helping children develop sustainable handwashing behaviors.
