• Waiting time is the time you earn after you meet specific requirements and are listed by your hospital for a transplant in the OPTN Computer System.
• It is one of many factors used to match organs to patients on the waiting list (patients on the waiting list are known as candidates).
• Having more waiting time may help you get a transplant sooner.

• It is a way to adjust a candidate’s wait time in the OPTN Waiting List.
• Transplant hospitals request waiting time modifications (PDF) on behalf of their candidates.

• The estimated glomerular filtration rate, or eGFR for short, measures how slowly or quickly kidneys remove a waste product called creatinine from the blood. This calculation helps doctors understand how sick a kidney patient is.
  • Some calculated GFRs that use a race factor are called race-inclusive calculations
  • Calculated GFRs that do not use a race factor are race-neutral calculations
• OPTN policies formerly did not specify the type of calculation that transplant hospitals must use when assessing patients for kidney transplant.
• Race-inclusive eGFR calculations give different results for Black patients that make Black patients' kidney function look better than it is and may have had an impact on when you began to accrue waiting time for a kidney transplant.
• Not all Black kidney candidates have had their eGFR measured with a race-inclusive calculation.
• Learn more about race and eGFR.

• The OPTN changed policy to require that transplant hospitals must use a race-neutral calculation to determine a kidney transplant candidate’s eGFR. Transplant hospitals are no longer allowed to use a race factor in calculations that estimate your kidney function.
• If you are Black, your treatment provider may have measured your kidney function with a race-inclusive eGFR.
• If your doctor used a race-inclusive eGFR calculation, you may qualify for a waiting time modification.

• Some candidates could gain more waiting time, which is an important factor in receiving a kidney offer.
• Your transplant program should provide documentation to support increasing your waiting time to the amount it would have been using a race-neutral eGFR calculation.

Kidney candidates qualify if all the following apply:

• Their transplant program registered them as Black or African American on the OPTN waiting list.
• Their transplant program has laboratory values or documentation showing that the candidate’s eGFR value was over 20 mL/min when their treatment provider used a race-inclusive eGFR calculation.
• Their transplant program can show that their eGFR value would be 20 mL/min or less if their treatment provider used a race-neutral eGFR calculation.

• No. Your waiting time will not be decreased for any reason. It will either stay the same or be increased.

• No. Adult and pediatric kidney patients may qualify for additional waiting time if they meet qualifying criteria according to OPTN policy.

• Your transplant team will notify you of the OPTN policy and will review your records.
• If they find that you are eligible for a waiting time modification, they will submit a request to the OPTN.

• Your transplant team is looking for evidence that you were disadvantaged due to the use of a race-inclusive eGFR calculation.
• Required documentation can include:
  • a lab report that shows a candidate’s eGFR value for Black and non-Black candidates (widely available at larger labs) with a race-inclusive calculated value of greater than 20 for Black candidates, and a value of less than 20 for non-Black candidates
    OR
  • a documented re-estimation of the candidate’s GFR with a race-neutral eGFR calculation, which shows an eGFR value of 20 or less
• It is the transplant program's responsibility to look for labs or documentation and while candidate participation is encouraged, it is not required.
• Learn more about race and eGFR.

• Yes, you should communicate with your transplant team if you feel you have information that would assist the evaluation.
• It is the transplant program's responsibility to look for labs or documentation and while candidate participation is encouraged, it is not required.
• Your transplant program must submit your documentation to the OPTN. Please do not send your materials to the OPTN Contractor (known as United Network for Organ Sharing, or UNOS).

• You may need to contact your referring doctor, your dialysis center, or other prior medical providers.
• These providers may have labs or documentation that your transplant hospital does not have in their system.
• It is the transplant program's responsibility to look for labs or documentation and while candidate participation is encouraged, it is not required.

• Candidates may provide their transplant program with supporting documentation at any time.
• Transplant hospitals can submit eGFR modifications for candidates at any time.

• It is possible that your treatment provider used a race-inclusive eGFR if your eGFR was calculated before July 27, 2022.
• Before that date, OPTN policy did not specify how transplant programs must calculate your eGFR.
• Talk to the transplant team where you are registered on the kidney transplant waiting list for more information about how your transplant program calculated your eGFR.

• Waiting time for non-Black candidates will not be impacted.
• Non-Black candidates do not qualify for eGFR waiting time modifications as those candidates would not have had their kidney function measured with a race-inclusive eGFR calculation.
• Black candidates who qualify for eGFR waiting time modification will get more waiting time. Waiting time is an important factor in receiving a kidney transplant. Black candidates who receive an eGFR waiting time modification may move higher up the matching system than other candidates with less waiting time.

• Talk to your transplant team. They are the best resource for specific information about your treatment including the calculation of your waiting time.
• If you receive care from a kidney doctor outside of your transplant hospital, ask your kidney doctor if they used a race-inclusive calculation of your kidney function. Share this information with your transplant team.
• For general questions, call the OPTN Patient Services line at (888) 894-6361. They are available Monday – Friday, 8:30 a.m. to 5 p.m. (ET).
