RFID is thus creating a paradigm shift in healthcare, moving it beyond the limitations of traditional methodologies such as barcoding and redefining how healthcare is delivered, setting a precedent for all future innovations.

What is RFID?

RFID represents a sophisticated innovation employing electromagnetic fields to identify and track labels affixed to items. These labels, or “tags,” are embedded with digital information that can be accessed from significant distances. This characteristic distinguishes RFID from barcode tags, requiring a direct line-of-sight for accurate reading.

RFID vs. Traditional Barcoding

While both RFID and barcoding serve the purpose of tracking and identifying objects, RFID offers distinct advantages that make it a superior choice in many applications.

One key advantage of RFID over traditional barcoding is the ability to read multiple tags simultaneously without line-of-sight. RFID uses radio waves to communicate between the tag and the reader, allowing quick and efficient data capture even in challenging environments. In contrast, barcoding requires direct visual contact with each barcode, which can be time-consuming and prone to errors when dealing with large quantities of items.

Another notable benefit of RFID is its ability to store and transmit more data than barcoding. RFID tags can hold a wealth of information, including unique identifiers, product details, and real-time sensor data. That enables enhanced inventory management, improved traceability, and increased operational efficiency.

RFID technology also offers superior durability and longevity compared to traditional barcodes. RFID tags are designed to withstand harsh conditions, such as temperature extremes, moisture, and physical stress, ensuring reliable performance throughout the lifecycle of the tagged items. In contrast, barcodes can easily damage or wear off, leading to scanning issues and compromised data accuracy.

How Medical RFID Tracking Works

Whether active or passive, RFID tags are attached to or embedded in hospital equipment or placed on tracking accessories worn by patients, visitors, and staff, relaying their position to RFID detectors. These detectors, located throughout the hospital, including corridors and wards, recognize the location of RFID tags and transmit this data to the cloud gateway through a secure firewall.

Once through the firewall, a streaming data processor funnels the raw information, including data about hospital assets, patients, and personnel, into a data reservoir. This reservoir acts as a primary repository, storing the information transmitted by RFID markers in its unaltered state. A big data repository then houses the filtered and processed data for subsequent analysis, focusing on areas such as hospital staff workflow efficiency and patient and asset movements.

The power of data analytics is harnessed to identify patterns and trends in the usage of hospital resources and the movement of tracked individuals, offering invaluable insights for enhancing asset availability, refining medical staff schedules, and improving patient safety.

A cornerstone of this system lies in the RFID tracking software’s business logic. It manages hospital asset requests, prioritizes events – for instance, if a patient exits the hospital premises without official discharge – and provides location data for patients, visitors, and staff members.

The staff application serves as a crucial tool for medical professionals and equipment technicians. It enables viewing the location of hospital assets, requesting their use, accessing patient location data, and receiving alerts about unusual patient or visitor behavior. Additionally, it allows supervisors to view the whereabouts of each unit’s staff and gather insights for workflow optimization.

Finally, the admin application allows for viewing and managing the list of monitored assets and tracked individuals, adding new assets and staff members, modifying essential data about tracked items and people, and authorizing access to the asset tracking system for medical and administrative personnel.
