๐ Background
Hand hygiene is a critical practice in preventing healthcare-associated infections, yet traditional monitoring methods often fall short due to the Hawthorne effect and high resource demands. The emergence of AI technology presents an opportunity to automate and objectively assess compliance, potentially transforming infection control practices in healthcare settings.
๐๏ธ Study
This scoping review followed the Joanna Briggs Institute (JBI) framework and PRISMA-ScR guidelines, analyzing articles published from January 2000 to September 2025 across five major databases. The review aimed to systematically map existing evidence, technical pathways, and implementation challenges related to AI in hand hygiene monitoring.
๐ Results
Out of 800 records screened, 45 studies were included, revealing that computer vision is the most prevalent technology used, accounting for 53.3% of the studies. While it demonstrated high accuracy in specific settings, the generalizability of these models remains a concern. Wearable sensors, although portable, showed slightly lower specificity compared to vision-based approaches. The review highlighted a significant gap in comprehensive fairness analysis and evaluation of clinical workflows.
๐ Impact and Implications
The findings of this review suggest that AI-based monitoring of hand hygiene could lead to more objective and scalable surveillance methods in healthcare. However, the field is still in its early stages, necessitating a shift towards implementation science to ensure that these technologies can be effectively integrated into clinical practice. Addressing ethical governance and conducting pragmatic trials will be crucial for demonstrating the long-term benefits of AI in healthcare settings.
๐ฎ Conclusion
This scoping review underscores the potential of AI to enhance hand hygiene compliance monitoring in healthcare. While promising, the field requires further research focused on implementation and ethical considerations to realize its full potential. As we move forward, it is essential to establish standardized practices and conduct larger studies to validate the effectiveness of these innovative technologies.

Artificial intelligence for monitoring hand hygiene compliance in healthcare settings: A scoping review.
Abstract
BACKGROUND: Hand hygiene is a fundamental measure for preventing healthcare-associated infections, yet traditional monitoring methods are significantly limited by the Hawthorne effect, high resource demands, and an inability to assess procedural quality. Artificial intelligence (AI) technology has emerged as a transformative, automated, and objective approach to address these long-standing challenges.
OBJECTIVE: This scoping review sought to systematically map the existing evidence, technical pathways, performance metrics, and implementation challenges of AI for monitoring hand hygiene compliance in healthcare settings.
METHODS: Following the Joanna Briggs Institute (JBI) methodological framework and PRISMA-ScR guidelines, we searched five major databases (PubMed, Scopus, Embase, Web of Science, and IEEE Xplore) for articles published between January 2000 and September 2025, supplemented by grey literature searching and backward citation tracking. Two reviewers independently screened records, assessed full-text reports for eligibility, and extracted data, which were synthesized using descriptive statistics and thematic analysis.
RESULTS: Of 800 records identified through database and supplementary searches, 45 studies (2007-2025) were included. The primary technical pathways identified were computer vision (53.3%), wearable sensors (24.4%), Internet of Things-integrated systems (13.3%), and radar/radio frequency-based systems (8.9%). While computer vision achieved high accuracy (95%) in setting-specific ICU models, performance dropped to 56% in generalizable models. Wearable systems demonstrated portability but showed 5%-10% lower specificity than vision-based approaches. Most evidence is derived from small-scale technical validations, with a significant lack of formal fairness analysis and evaluation of clinical workflows or cost-effectiveness.
CONCLUSION: AI-based hand hygiene monitoring shows promise for supporting more objective and scalable hand hygiene surveillance in healthcare settings. However, the field remains at a largely pre-translational stage. Future research should shift from technical feasibility toward implementation science, focusing on establishing standardized motion databases, evaluating ethical governance (e.g., privacy and automation bias), and conducting pragmatic trials to demonstrate sustained clinical benefit and organizational sustainability.
