Implementation date:
December 5, 2018
At-a-glance:
Every year, the OPTN/UNOS Board of Directors review and approve changes to the HLA and unacceptable antigen equivalency tables. We are in the process of updating those tables now and the changes will take effect Dec. 5, 2018. At that time, you’ll notice changes to HLA and the unacceptable antigen dropdown menus throughout the UNet, DonorNet, Waitlist, TIEDI and KPD applications. We’ll outline what is specifically changing below. It is important that you familiarize yourself with everything new.
What specific changes are coming?
Removals/relabeling
We are removing and relabeling two values throughout the entire system.
- B4415 will now display as B44
- DR103 will now display as DR01:03
Additional dropdown selections
You will see additional values for all loci (except HLA-DQA1). For DR51, DR52, DR53, you will see the following new values:
DR51: 5*01, 5*01:01, 5*01:02, 5*02, 5*02:02
DR52: 3*01, 3*01:01, 3*02, 3*02:01, 3*02:02, 3*03, 3*03:01
DR53: 4*01, 4*01:01, 4*01:03
CPRA calculation changes
Whenever we modify unacceptable antigens, candidate CPRA scores may change slightly.
New features:
Unacceptable antigen section in Waitlist and KPD and CPRA calculator:
You will now be able to either manually add unacceptable antigens (the way you have been doing) or you copy and paste a comma delimited list of unacceptable antigen values (ex. A1,A01:01,DR01:01,DR523*01:01). We are changing the look of the Waitlist CPRA calculator in the Reports section so that it resembles this new unacceptable antigen portion on a candidate page.
The candidate page is now an additional place where you can calculate CPRA. You will now be able to see real-time changes in the CPRA score but it won’t be stored until you hit the save button.
Import Unacceptable Antigens to Active Waiting List
If you used this feature in the past, you needed to know how the antigen code was labeled in the database, which may have differed from what you saw in UNet.
For example:
Currently, an import file may look like this:
A201, BW4, DR0401, DR5252
Upon implementation, the import file should look like this:
A02:01, BW4, DR04:01, DR525*01:01
KPD eligibility:
If you have entered an HLA value for your candidate under DR51, DR52, or DR53, we will automatically prefill a newly created second dropdown column with a negative value. This ensures that your candidate does not become ineligible for the organ offer.
Policy Resources:
- You’ll find the Antigen Equivalence tables in Policy 4, located on the OPTN website.
- This policy notice explains the board’s responsibility for reviewing and approving equivalency table updates each year.
