1. HCUP reports that it is the most frequent and fastest-growing procedure performed during a hospital stay.
The rate of human error occurring during these procedures is extremely high, at 1 in 10,000
2, and has been virtually unchanged for over 40 years
3. The results range from blood infections to death in some cases. In almost every instance, these errors could have been prevented at various stages in the process. The most prevalent stage for errors – and thus best stage to focus on error prevention – occurs at the bedside. Human error underlies at least fifty percent of the fatalities related to blood transfusions

Any health professional can tell you how easily these errors happen, from dealing with two patients with the same surname, to picking up the wrong chart accidentally. Distractions endemic to the hospital environment make clinicians more likely to make these types of mistakes, and can be very costly.
RFID: An Advanced “Safety Layer”Despite various improvement measures, little change has resulted until recent advances in technology. Experts recommend the implementation of Radio Frequency Identification (RFID), as a more advanced “safety-layer around the application of blood products” to considerably increase transfusion safety
4. RFID verification for blood transfusion processes cuts verification time down significantly, while improving its accuracy and eliminating the opportunity for various types of human error.
RFID for lab & sample tracking directly addresses blood transfusion errors by:
- Performing positive patient identification
- Automating cross-checking of information across systems
- Verifying transfusion blood type matches patients’ blood type found in the system
- Documenting the chain of contact between staff and patients
- Monitoring the temperature conditions during the shipping and storing of blood products (on an item level)
And can notify the proper personnel by page, email or other predetermined means when:
- The information on the patient’s wristband, doesn’t match the information in the system
- The cross-check of information in the system yields a potential conflict, like differing blood types
- The temperature range of blood products fell below or rose higher than the required range for safe transfusion (down to item level) during transport or storage
RFID vs. Bar Coding for Lab & Sample Tracking
Bar coding is a commonly used solution that has reduced blood transfusion and lab errors. There is no question that it works. RFID is to bar codes what ears are to eyes.
Bar codes are like your eyes. You manually scan the bar code and it sees the information. It cannot see through walls (or bed sheets), see around corners, or see more than one item at a time. RFID technologies, on the other hand, are like your ears that allow hearing of data at almost instantaneous rates without voluntary actions. While bar codes (eyes) require that you focus using your line of sight (bar code reader), RFID can hear many things at once, and automatically process the information without deliberate action.
An example of where this makes a big difference is location of specific items. Bar coding requires scanning individual items to locate the correct one, while RFID reads the entire contents of a cart or storage cabinet simultaneously to determine if it contains the item needed. RFID offers all-the-time reads, which documents real time inventory and availability of the types and amounts of blood supply. It automatically checks-in and checks-out the blood from the storage area.
Automatic expiration date notification, restocking notification, temperature monitoring and locating recalled items are all other benefits RFID provides over bar coding. By automating these types of processes, the system can generate notifications to whomever you choose, through whatever electronic methods you pre-set in the system rules.
RFID also has the ability to encompass and interoperate with systems you already have in place, such as bar coding systems, EHRs, paging systems, security, scheduling, maintenance, etc. This enhances the capabilities and effectiveness of each individual component.
In addition to interoperability, the flexibility that RFID offers is also a key feature. It offers the ability to control distances at which the tags can be read, and the intervals at which the reads are recorded and forwarded to the assigned systems. Using the system for various functions in concert with lab tracking offers even more benefits in terms of efficiency, productivity and risk reduction. Inventory Management, Patient & Staff Tracking, Medication Tracking and Asset Tracking & Maintenance management are examples of the common applications that can be included.
Dynamic RFID Solutions offer Scalability and Flexibility
Like adding additional bar code labels into a bar coding system, once the infrastructure is in place, the RFID solution that DCC provides can easily be scaled. You can add additional RFID tags to automatically track additional assets or inventory on a case-level or and item-level basis to further increase the efficiency of processes.
Niche and/or proprietary solutions offer certain benefits for specific requirements, but have several drawbacks as well. DCC evaluates your needs and provides the best solution to meet them rather than endorsing a specific technology or product.
We are technology-neutral in the sense that we have partnered with several RFID hardware and tag manufacturers, as well as software providers to meet the diverse needs of health care customers. We have pre-screened the available devices and software from across the industry for the health care environment, in terms of quality, value and functionality. Our solution can incorporate multiple technologies as necessary to solve your particular problem.
An article published in Integrated Solutions magazine used a restaurant scenario as a comparison to illustrate the benefits of working with a solutions integrator.
“Companies desiring a seat at the RFID table can order from a vast menu of hardware, middleware, and software components. When you have a meal at a restaurant, you don’t place an order with the steak provider, another with the lobster farm, and another with a vineyard. You place an order with the server, and the chef prepares the meal to your specifications. In the RFID world, you can use an integrator much like you would your server and chef in the restaurant scenario. An RFID integrator can listen to your goals and objectives, make recommendations, then design a solution that meets your specifications."
DCC’s solution is not proprietary, and therefore is quite flexible and easily expanded. As the ROI builds, funding becomes available to grow your use of RFID. The RFID infrastructure you will need to scale out your applications, or include other types of tracking applications will be in place, whether or not you choose to work with Dynamic again in the future.
Our 30 year history providing IT solutions and 90%-plus rate of repeat business illustrates that we build valuable relationships with our partners and customers. We strive for 100% customer satisfaction with each client, and operate with forthright business practices. Chances are, after tasting our menu you will again patronize our restaurant and allow us to serve you. (Download PDF)
