I’ve just started using OpenELIS and originally the barcodes were generating sequential numbering for new patients. Which was working well. Suddenly it has switched to generating letters to identify a patient registration, which is more difficult to manage. Is this normal?
The barcode formats are configurable, the alphanumeric (which contains no vowels to make it easy to tell the difference between 0 and O, or I and 1) was to make more lab numbers available in fewer digits to make the workload of technicians a little easier, and the barcode labels easier to scan.
You can switch to numeric by clicking admin - Lab Number Management, and change from alphanumeric to “legacy”
