Project to Update Refusal Codes

The OPTN Final Rule requires transplant programs to provide to the OPTN “reasons for refusal” of organ offers made to candidates registered at their programs (see 42 C.F.R. §121.7(b)(4)), and OPTN Policy 18.3: Recording and Reporting the Outcomes of Organ Offers accordingly requires these reasons to be reported to the OPTN. The OPTN Data Advisory Committee (DAC) is working to provide recommendations to the OPTN Board of Directors on updating refusal codes used by transplant programs and OPOs to indicate why a specific organ offer was not accepted for a specific candidate.

The OPTN has received community feedback that the current codes are too vague, need clarification, and are outdated. Additionally, some codes cover multiple reasons for refusal, such as “age or quality.” To address these concerns, and in light of the recommendations of the Systems Performance Committee, the DAC has collaborated with OPTN committee members to develop a revised list of codes.

Revising the list of refusal codes will support increased efficiency of the OPTN through better understanding of refusal behaviors. Offering members more options for reporting why an offered organ is refused will provide more robust data to develop improved allocation strategies to:

  • Reduce cold ischemic time
  • Reduce number of discards
  • Increase the number of transplants

These revisions would not change or add data collection, but provide an updated list of options under the primary refusal and secondary refusal drop downs in the offer details form section of DonorNet®.

Opportunity to provide input now closed

The opportunity to provide input was open March 8-21, 2021.  

Thank you to all who provided their thoughts and recommendations. The feedback submitted will be used to inform the final list of refusal codes reviewed and approved by the OPTN Board of Directors. Once approved, implementation and notice to OPTN members will follow.

About refusal codes

OPOs and transplant programs strive to place the right organ with the right candidate. On occasion, this means that a transplant program may choose to refuse certain organ offers for reasons related to the candidate, the donor, or OPO or transplant hospital operational issues. When this occurs, a refusal reason is entered into DonorNet®. These reasons are labeled with numerical values that are referred to as refusal codes.

Refusal codes are used by transplant programs and OPOs when reviewing their acceptance practices as well as in research analysis to better understand:

  • Why an organ was declined
  • Identify trends in acceptance behaviors
  • Inform proposed solutions to increase acceptance rates

The current list of refusal codes has not been updated since 2004 and data shows the majority of the codes are underutilized. In 2018, 17 of the total 23 currently used refusal codes accounted for less than 4% of refusals while 70% of all refusal reasons were listed as “830 Donor Age or Quality.” To promote more specific collection for refusal reasons associated with Donor Age or Quality, several codes have been proposed that include:

  • DCD donor
  • Donor age
  • Donor instability/ high vasopressor usage
  • Prolonged downtime/CPR

Ensuring the codes are relevant and discrete, or mutually exclusive, allows for the data to be more actionable.
