A.1 Working with barcodes
To reduce the probability of the barcode being misread, it is strongly recommended that you use
the configuration options for patient and/or operator ID validation as applicable to your specific
workflow. These options are:
■ check ID against list or
■ check ID for length
1
■ check if the scanned bar code type is allowed and activated in the DMS
■ use barcodes with check digits
In combination with the above options or as a single measure, use an appropriate barcode mask
if this is compatible with the structure of your barcode content.
Always make sure that the entire barcode is covered by the green light frame when scanning.
WARNING
Risk of barcode read errors
If a barcode is read incorrectly, this may lead to patient misidentification
and therefore to inappropriate therapy decisions.
When creating patient or operator barcodes, always adhere to the
applicable international IEC/ISO standards for the respective barcode
symbology. In particular, ensure that barcode size and print quality (as
defined in ISO/IEC 15416 and 15415) are adequate. Inadequate print size
and/or quality may lead to erroneous decoding. In addition every user
must carry out a plausibility check on all data scanned into and displayed
by the instrument.
1. If no operator/patient list can be used, it is recommended that you at least set a minimum length for
the respective ID, even if your facility uses IDs of varying length.
