Problem context

Maintaining high and consistent hand hygiene compliance among healthcare staff is critical to reducing healthcare-associated infections (HAIs), but manual observation is inconsistent and labor-intensive. The client required an automated connected solution that could reliably detect hand hygiene events, monitor compliance, and provide actionable insights to clinical teams and operations leaders.

Constraints

  • Compliance detection must occur in real-world clinical environments with varying workflows
  • Sensors must distinguish valid hygiene events from noise
  • System must support real-time alerts without disrupting clinical care
  • Data must be usable at scale for quality improvement and reporting

Engineering decisions

Decision: Deploy a network of IoT sensors with edge processing at discrete points of care
Reason: Local edge processing enables near-instant detection of hygiene events while reducing latency and wireless load.
Trade-off: Requires robust sensor calibration and edge firmware complexity.
Decision: Use BLE/NFMI and proximity detection for event triggering
Reason: Proximity-based detection improves accuracy for in-room and point-of-care events compared to pure visual observation.
Trade-off: Requires integration with multiple communication layers and filtering to reduce false positives.
Decision: Integrate secure cloud infrastructure for aggregated reporting
Reason: Cloud analytics provides dashboards and trend data accessible to quality teams.
Trade-off: Added responsibility for data security and uptime.

System overview

The engineered system consists of distributed hygiene sensors placed near dispensers and care areas; wearable or badge-based devices for personnel interaction; edge modules that capture real-time compliance events and send them securely; a cloud platform with dashboards, analytics, and alerting logic; and APIs for integration with clinical quality systems. This architecture delivers reliable event capture, automated compliance tracking, and actionable insights without requiring manual logging.

Outcome

Real-time tracking of hygiene compliance in clinical environments. Automated alerts and analytics for infection prevention teams. Scalable IoT infrastructure supporting multiple facilities. Data-driven improvements in hygiene adherence and operational oversight.
