An ever present concern for hospitals is the transportation of clinical samples from the operating theatre to the laboratory for analysis. After each procedure, the hospital has a responsibility to ensure that data for the clinical sample is accurately recorded and that the clinical sample is taken from the theatre to the lab in a timely manner. Furthermore, it is important to know the chain of custody for the clinical sample at any given time.
Information for all tracked items is stored centrally on an RFID
It is important to note that no personal or medical information is stored by ASD - only tracking information about the RFID tags and labels.
|Manual paper-based process.|
|Poor chain of custody.|
|Unreliable or missing data.|
By having an unreliable procedure for monitoring and transporting clinical samples they may go missing, patients are unable to be diagnosed, patient security/safety is at risk and the hospital could be subjected to litigation.
Once clinical samples are RFID-tagged and known to the RFID
Transactions that users forgot to enter into the system become a thing of the past. If unexpected or unauthorised movements occur, the system will issue alerts within a defined timeframe to the appropriate personnel via e-mail or text message to highlight the movement.
An RFID label is attached to the container of the clinical sample as it is removed from the operating theatre and linked to the patient via the laboratory test order. By doing this we know the details of the patient that is undergoing the procedure. We are also able to determine the staff member, a surgeon for example, that is operating on the patient as well as any other staff in attendance.
Hospital porters and orderlies are issued with UHF RFID enabled ID badges and can be easily associated with the samples that they are transporting through the hospital premises. Again, the data is automatically and transparently recorded with no line-of-sight requirement. RFID
At the laboratory the staff take ownership of the sample, again using their RFID enabled ID badge if required. In this way, a chain of custody and a real-time tracking of the samples through the facility can be built up. The benefits of this are as follows:
|Automatic data collection.|
|Knowledge of the location of the clinical sample.|
|Chain of custody is established.|
