Removal of DSA and region from pancreas allocation policy
At its December 2019 meeting, the OPTN Board of Directors approved a policy to remove DSA, and region from pancreas allocation. This proposal developed as a result of the OPTN Board of Directors’ 2018 directive that organ-specific committees remove DSA and region from allocation policies to align with the OPTN Final Rule. The Final Rule requires that policies “shall not be based on the candidate’s place of residence or place of listing, except to the extent required” by the other requirements of the Rule.
Summary of policy changes
- These changes remove DSA and region as units of allocation in pancreas policy. Allocation instead has a first unit of a 250 nautical mile (NM) fixed-distance circle, with the donor hospital at its center. View a map visualization of donor hospitals within 250NM of transplant centers.
- This policy adds new points to a candidate’s total allocation score reflecting the distance between the transplant hospital where the candidate is listed and the donor hospital. Find a visual aid to proximity points below, under Guidance.
- Candidates inside the circle and located closest to the donor hospital can receive a maximum of 2 proximity points.
- Proximity points decrease linearly out to the 250 NM circle, where a candidate at that distance would receive no additional proximity points.
- If allocation moves outside of the 250 NM circle, proximity points are then awarded to candidates outside of that circle.
- Candidates outside of the circle can receive a maximum of 4 proximity points, depending on the proximity of their center of listing to the donor hospital.
- As with proximity points inside the circle, proximity points outside the circle decrease in a linear fashion, out to 2500 NM away from the donor hospital.
- Proximity points only prioritize candidates within their classification. No candidate listed at a hospital outside of the 250 NM circle would receive proximity priority until all candidates inside the 250 NM have been considered for an organ offer.
- This policy also makes changes to facilitated pancreas placement to make it more consistent with the changes to allocation. Refer to section 11.6 in the policy notice below for details on changes to facilitated pancreas allocation.
- The additional change of policy to allocation of kidneys and pancreata recovered in Alaska will make Seattle-Tacoma International Airport the substitute for the donor hospital for purposes of allocating donor pancreata recovered in Alaska. As there are currently no transplant programs in the state of Alaska, making the Sea-Tac airport the center of the 250NM circle helps maximize utilization of deceased donor kidneys and pancreata procured there and avoid unnecessary delays in placement. Find a visual aid for allocation of Alaskan organs below, under Guidance.

These policies do not change the current routine monitoring of members. All policy requirements, as well as any data entered in UNetSM, may be subject to OPTN review, and members are required to provide documentation as requested. OPTN contractor staff will continue to review deceased donor match runs that result in a transplanted organ to ensure that allocation was carried out according to OPTN policy, and staff will continue to investigate potential policy violations.
