Regarding the November 20, 2025 OPTN Board meeting vote to alter the Lung Transplant Continuous Allocation Score (CAS) points and ratios in order to address concerns about Allocation out of Sequence (AOOS).

I am writing to express my strong desire for HRSA/OPTN Board to reverse the decision voted on during the November 20, 2025 Board meeting to remove five points from categories describing a recipient's medical condition and reallocating them to the efficiency category, returning the CAS point allocation and ratios to the pre November 20, 2025 vote levels.

This matters to me because Why would you want to make it harder to obtain a transplant? My great nephew is alive only because he was able to receive a double lung transplant. Under the rules that you have now set he would probably no longer be with us.
Making it harder to qualify to my way of thinking means that more people will pass away as they sit on the waiting list that would have received a transplant under the old rules.
My great nephew would most likely be one who did not qualify under the new rules that you are imposing.
Think about what you are doing and go back to the old way. Don't change horses in mid stream.

Additionally, I share the concerns expressed by the Lung Transplant Foundation letter directed to HRSA and the OPTN Board of Directors, submitted via the Critical Comments and Directives Pathway on April 13, 2026, and signed on to by seventeen distinct lung disease patient advocacy organizations, identifying the following primary concern areas as reasons to oppose this change to the CAS:

- Bucking decades of protocol, no prospective public comment period occurred before this major policy change, and no clinical evidence was supplied justifying the use of the emergency pathway at the time of the vote.
- No clinical rationale was given for ignoring the recommendation of the Lung Committee, which unanimously opposed this change to the CAS, and no solutions were proposed to address the concern that initial modeling suggested that these changes would increase the waitlist mortality for high-risk individuals.
- The change in protocol from extensive modeling before policy changes are implemented to minimal modeling with an intention of catching problems after they occur will endanger lives unnecessarily.
- Patient voices and specialized lung transplant expert opinion should be centered at every stage of OPTN policy development, including the identification of problems, proposed solutions, and the implementation of new policy geared at addressing identified problems.

Thank you again for the opportunity to comment. I sincerely hope that, based on the consistent and unanimous dissent from lung transplant professionals, lung transplant candidates/recipients, and community members, HRSA and the OPTN Board of Directors will reverse the November 20, 2025 vote and restore the CAS to its previous point and ratio allocation.

Sincerely,

This matters to me because with this new change lives are at risk. My husband who received his DLT over a year ago would not be with us today if he fell under the new policy. My young children would not have their father.

We write as medical and…

We write as medical and surgical directors of lung transplant programs in California and Washington to oppose the emergency amendment to the lung Composite Allocation Score (CAS) implemented by the OPTN on May 7, 2026. This change raised the weight of geographic placement efficiency from 10 to 15 points and adopted a steeper distance-weighting function. We are concerned this change was made without sufficient deliberation and will harm lung transplant candidates throughout the country, including reducing access to lung transplantation for patients in our states. The amendment does not advance the goals it is meant to achieve in a manner sufficient to justify these harms. We urge the OPTN to suspend this amendment and to reconsider any change of this kind through its normal modeling and public-comment process.
Our first concern is the process by which this change was made. Continuous distribution and the CAS were adopted in 2023 in large part to reduce geographic disparities in donor lung allocation and to prioritize medical urgency, expected benefit and access for biologically disadvantaged candidates. The May 2026 emergency amendment moves in the opposite direction, increasing the prioritization of geography, in conflict with the Final Rule. Yet, the amendment was implemented without public comment, over the opposition of the OPTN Lung Transplantation Committee, and despite concerns expressed by the lung transplant community that this change would worsen geographic disparities in lung transplant waitlist outcomes. A change of this magnitude, which contradicts the established principles of donor organ allocation, should have been subject to the full scrutiny of the standard vetting process.
Second, the consequences of the amendment, which were not transparently reported prior to implementation, are likely to cause significant harm to lung transplant candidates across the country, and especially so in California and Washington. A recently published analysis by Valapour and colleagues (Chest 2026 May 22:S0012-3692(26)00652-5. doi: 10.1016/j.chest.2026.05.019) highlights and quantifies these consequences. They find that access to compatible donors was already strongly shaped by geography even before the emergency amendment was implemented, with West Coast centers having approximately 30% lower adjusted donor availability than those in the Midwest. Applying the emergency amendment’s parameters decreases donor availability in every region. Further, it more than doubles the already significant gap between the best- and worst-geographically positioned centers. This negative impact disproportionately affects lung transplant centers in California and Washington, leaving our patients with the worst adjusted donor supply in the nation and at a significant disadvantage for undergoing life-saving lung transplants. Patients in California and Washington are as deserving of access to lung transplantation as patients elsewhere in the country.
Our third concern is the lack of clarity on whether the amendment will even achieve its intended goals, and that any putative benefits with respect to these goals were not balanced against the foundational principles of donor organ allocation as stated in the Final Rule. We recognize the burden of long-distance procurement and understand that allocation out of OPTN sequence (AOOS) is a real and pressing problem. However, improvements in organ preservation technology and logistics are already diminishing the negative impacts of distance on efficiency, and the potential efficiency benefits of the amendment remain undefined and unproven. The emergency amendment is a blunt instrument that may or may not reduce AOOS or improve efficiency, while the potential harms to lung transplant candidates in California, Washington and across the country have now been clearly quantified. These conflicting priorities should have been defined, analyzed and debated prior to the implementation of any change.
Untested efforts to promote efficiency and reduce AOOS should not come at the cost of worsened waitlist outcomes for lung transplant candidates. This is especially true when there are disproportionate negative impacts on patients who happen to live further from the geographic center of the country. By prioritizing donor lung allocation based on geography rather than medical considerations, the emergency amendment operationalizes the happenstance of geography into reduced access, longer waiting times and more waitlist deaths. This is precisely the type of disparity that continuous distribution was created to remedy.
We therefore ask the OPTN to:
(1) revoke the May 7, 2026 amendment; and
(2) subject any future change in placement-efficiency weighting to full modeling and public comment, with transparent reporting of anticipated regional and center-level effects on waitlist outcomes before any changes are implemented.
We make these requests out of our sense of responsibility to the patients we serve and who will be harmed by this new policy, and we welcome the opportunity to work with the OPTN as this issue is reconsidered.
