Privacy-Preserving Auditable Hygiene Compliance Using Hyperledger Fabric in Hospital Environments

Abstract

This research introduces a novel decentralized system de- signed to improve hand hygiene protocols in clinical environments, aim- ing to lower the incidence of hospital-acquired infections (HAIs). Moni- toring techniques often fail to verify adherence or maintain secure, ver- ifiable 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 Fab- ric 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 main- tain hand hygiene practices. The proposed system ensures data integrity, preserves user privacy, and provides transparent audit trails.
