This research introduces a novel decentralized system designed to improve hand hygiene protocols in clinical environments, aiming to lower the incidence of hospital-acquired infections (HAIs). Monitoring techniques often fail to verify adherence or maintain secure, verifiable records, leading to audit challenges and increased infection risks. The proposed solution integrates a custom-trained YOLOv8 model to detect hand hygiene-related behaviors from real-time image and video streams, enhancing hygiene alerts for healthcare workers more accurate with a comprehensive tracking and tracing mechanism. Detected events are cryptographically anonymized and stored on a Hyperledger Fabric blockchain, ensuring immutable and transparent compliance records. Compared to traditional monitoring methods, recorded events are more accurate and practical for compliance checks and audit purposes to maintain hand hygiene practices. The proposed system ensures data integrity, preserves user privacy, and provides transparent audit trails.

摘要

This research introduces a novel decentralized system designed to improve hand hygiene protocols in clinical environments, aiming to lower the incidence of hospital-acquired infections (HAIs). Monitoring techniques often fail to verify adherence or maintain secure, verifiable records, leading to audit challenges and increased infection risks. The proposed solution integrates a custom-trained YOLOv8 model to detect hand hygiene-related behaviors from real-time image and video streams, enhancing hygiene alerts for healthcare workers more accurate with a comprehensive tracking and tracing mechanism. Detected events are cryptographically anonymized and stored on a Hyperledger Fabric blockchain, ensuring immutable and transparent compliance records. Compared to traditional monitoring methods, recorded events are more accurate and practical for compliance checks and audit purposes to maintain hand hygiene practices. The proposed system ensures data integrity, preserves user privacy, and provides transparent audit trails.
