Case Study: Implementation of a UHF RFID-based Medical Equipment Tracking System at Homerton University Hospital NHS Foundation Trust
The deployment of end-to-end visibility for thousands of mobile assets enabled the hospital to reduce operational costs, improve patient care quality, and optimize management of high-value equipment.
Company and Production Context
Homerton University Hospital NHS Foundation Trust is a state hospital in London (Hackney borough) with over 500 beds, 11 wards, intensive care units, maternity, and pediatric departments. Staff work across more than 75 community sites. Annually, the hospital manages thousands of mobile medical assets: infusion pumps, monitors, wheelchairs, and other equipment. The focus is on operational access to equipment, minimizing delays in patient care, and optimizing costs within the NHS. The implementation of a UHF RAIN RFID tracking system (extended to iAssets) was carried out in partnership with Idox Health.
Problems Before Implementation
Prior to RFID implementation, the hospital faced typical asset management problems for large medical institutions:
- Low Visibility: Equipment location was unknown, and searching could take hours or even days.
- High Labor Costs: Medical staff spent up to 30% of their time searching for necessary equipment.
- Losses and Theft: 10–20% of assets were lost or written off annually.
- Inefficient Stock: Equipment overstock due to lack of real-time availability data, leading to unnecessary purchases and rentals.
- Patient Risks: Delays in care and potential risks from using faulty or overdue maintenance equipment.
Solution and Architecture
A comprehensive system based on passive UHF RAIN RFID technologies was implemented:
- Tags: All mobile assets were tagged with durable passive UHF RFID tags (EPC Gen2 standard, Impinj Monza chips). Tags are associated with existing iFIT barcodes. Tagging is performed upon equipment entry into the hospital.
- Equipment: Fixed Impinj Speedway R420 readers are installed at key control points: department entrances/exits, choke points. Staff use handheld readers for mobile inventory and room-level scanning.
- Integration: The Idox Health iAssets/iFIT platform serves as the unified data management system for equipment. It is integrated with the hospital's inventory systems.
- Process: The system enables bulk reading without line-of-sight, allowing scanning of all equipment in a room within seconds at distances up to 5–8 meters.
Process After Implementation (As-is / To-be)
| As-is (Before) | To-be (After) |
|---|---|
| Manual search of equipment via records and visual inspection | Automatic registration of movements through checkpoints in real-time |
| Periodic inventory with barcode scanners (took hours) | Instant bulk scanning of rooms with handheld readers (seconds) |
| Lack of up-to-date information on location and status | Precise asset localization and alerts for maintenance or expiry |
| Random distribution and overstocking | Optimized equipment distribution based on data and instant auditing |
Results (12–36 months)
- Inventory Accuracy: Achieved 98–99.9%.
- Equipment Search Time: Reduced by 30–70%.
- Asset Auditing: Conducted in seconds instead of many hours.
- Asset Losses: Decreased by 10–30%.
- Equipment Utilization: Increased by 20–40% due to better distribution.
- Maintenance Rates: Improved timeliness of servicing, reducing patient risk.
- Stock Management: Overstock identified and eliminated, equipment library optimized.
Economic Effect / ROI
- Labor Cost Reduction: For search and inventory tasks — by 30–60%.
- Procurement Optimization: Minimization of unnecessary purchases and rentals saved 10–30% on equipment costs.
- Loss Reduction: Direct savings from reduced loss and write-offs of assets.
- Payback Period (PP): 18–48 months due to optimized inventory management and operational efficiency.
- ROI (over 3–5 years): Expected in the range of 200–400%, depending on the scale of tagged assets and depth of integration with the procurement system.

FAQ
What problems did the RFID implementation solve at Homerton Hospital?
The system solved the problem of low equipment location visibility (search took hours), high staff labor costs for searching (up to 30% of time), frequent asset losses (10–20% annually), overstocking, and delays in patient care.
How is the RFID asset tracking system structured?
All equipment is tagged with passive UHF RFID tags (EPC Gen2). Fixed readers at entry/exit points track movement, while handheld readers enable inventory of an entire room in seconds. Data is managed by the Idox Health iAssets platform.
What economic effect was achieved?
Reduction in labor costs for search and inventory by 30–60%, savings on equipment purchases and rentals (10–30%), reduction in losses from misplaced assets. The payback period was 18–48 months with an ROI of 200–400% over 3–5 years.
