How does RFID work?

RFID works similar to barcode technology, except with a few highlighted characteristics. It consists of a reader, which could be a handheld or embedded to something like a door. The reader does not need direct line of sight to read tag data, whereas the barcode mechanism does require direct line of sight. Once the reader reads the RFID tags, it collects data from it and sends it to a cloud-hosted software or local network, for processing. Only authorized personnel will have access to the information being transmitted for the RFID reader to the system. The data collected from RFID connected with other applications enable functionalities including patient records, bed availability databases, and much more. RFID technology provides highly accurate data and real-time visibility.

RFID tags

The RFID tag is a lightweight item that can be attached to the wrist of patients and medical staff. It can even be attached to a baby’s ankle, which is especially useful for monitoring babies at pediatric and neonatal wards. Each RFID system has a unique number. Its signals are transmitted over a secure wireless network, which enables real-time monitoring and location tracking. Alarms go off whenever the RFID tag goes beyond the defined perimeters. There are two main types of RFID tags as follows: Active RFID Active RFID works on battery-powered RFID tags that keep broadcasting their own signals. They can accurately track real-time location of objects. They also provide longer read ranges than passive RFID tags. However, active RFID tags are more expensive. Passive RFID Passive RFID technology does not use an internal power source. Passive RFID tags are powered electromagnetic energy transmitted from an RFID reading device. Passive RFID is typically used in applications that involve access control, file tracking, smart labeling, and race timing. Passive RFID is an economical option to use in many industries including healthcare.

Applications of RFID in healthcare

RFID is used in a variety of applications and processes in the healthcare sector, including the following; Asset tracking Sterile services tracking Tracking reusable PPE Implant tracking with smart cabinets Baby tagging GS1 asset labeling Temperature and humidity monitoring Theater inventory management Medical staff safety Patient safety Access control Hospital visitors tracking

Why use RFID?

Hospitals and other healthcare facilities use RFID technology due to its multitude of benefits including the following: Improved patient safety Manage surgical tools Improved patient workflows Improved asset management Easy management of support staff Automate supply chain management and replenishment Manage locations of medical devices, notes, and IT equipment Authenticate quality processes and sterilization procedures

The benefits of RFID technology in different applications in healthcare

Here is how RFID benefits within different applications in the healthcare sector.

  • Asset management

Asset management is an essential functionality in healthcare, given the high costs involved in purchasing medical equipment. It helps prevent tampering and theft of valuable medical assets in hospitals. RFID solutions provide medical asset management by providing real-time location of equipment. 

RFID technology can also help find the location of a specific piece of medical equipment fast, rather than spending time trying to find it in various rooms across different departments. Large hospitals have several floors with a large number of medical equipment, which can be hard to locate. RFID makes finding these equipment a seamless process.

  • Infant safety

The safety of newborn babies is a major concern in the US and all over the world. There have been many incidents of babies gone missing, either intentionally or being accidentally switched at birth. RFID solutions enable monitoring and tracking of babies in maternity, neonatal, and pediatric wards. The RFID tag is attached to the baby’s wrist or ankle, while a similar tag with a unique identifier is attached to the mother’s wrist. It ensures that the babies are paired with their mothers and not switched by mistake.

  • Patient safety and efficient care

The improved efficiency in patient care is one of the major benefits of RFID solutions implemented in hospitals. RFID technology paired with cloud-based software can improve turnaround time by about 25 minutes in hospitals. It can make a significant impact on critical situations where every second can mean the difference between life and death. 

RFID solutions also streamline the entire process of patient care, starting from registration to surgery and postoperative recovery. Patient locations are also tracked in real-time to ensure their safety. Alerts are sent to the relevant staff, whenever a patient goes beyond his permitted boundaries, if any. Real-time tracking and monitoring ensures patient safety in hospitals.

  • Inventory control

RFID technology assists in managing the inventory in a hospital. It ensures the availability of medicine, medical devices, and other equipment. It is vital to have everything in hand in a hospital, especially when required to conduct any critical or emergency procedures. The last thing the medical staff needs to know is that the hospital has run out of essential surgical supplies or has malfunctioning equipment. From heart pumps to bed pans, everything in the inventory is controlled and monitored via RFID solutions. It also helps track medical supplies including the ordering and sorting of prescription drugs via the system.

  • Quality control

Even with an advanced inventory control system, it is still essential to have an advanced quality control mechanism to provide the best possible services to patients. Patients need to be given the correct medication in the required dosages. RFID tags allow this by providing the relevant medication and dosage details to medical personnel so that they can make informed decisions. 

  • Monitoring critical systems

The healthcare industry involves the use of many critical systems from medical devices to surgery equipment. Each of these devices and equipment plays a vital role in providing high-quality medical services. RFID tags ensure reduced errors and better tracking of equipment in laboratories such as test tubes and blood vials.
