Beneath is a graph exhibiting a development that exploded in the course of the 2020s:
What is that this depicting? Compute use for AI? Crispr gene edits per yr?
No, that is one other, a lot less-known instance of large development these previous a number of years. It is a chart of the variety of pancreases (or, to make use of the proper plural, “pancreata”) collected every year from lifeless our bodies within the US for analysis functions:
How this occurred is not any thriller. The surge is, by all accounts, attributable to a regulation that took impact in 2021 targeted on teams known as organ procurement organizations (OPOs).
You most likely haven’t heard of OPOs, however when you or anybody you understand has ever acquired an organ transplant, they’re those who procured it. OPOs are nonprofit, nongovernmental our bodies to which the US outsources the job of accumulating organs from deceased organ donors. Every OPO has a monopoly on restoration of all organs in a specific geographic space; there are 55 teams, a few of which solely cowl a part of a state and a few of which cowl a number of states.
For a while now, critics have argued that OPOs are massively underusing deceased donor organs. One report from 2019 estimated that yearly 28,000 usable organs (largely badly wanted kidneys but additionally pancreata, hearts, livers, and many others.) are faraway from deceased donors however by no means used; one other put the quantity at 75,000. This, when the nationwide waitlist for organs is greater than 100,000 individuals lengthy.
OPOs are usually not paid to gather these organs per se: They’re entitled to one hundred pc reimbursement of prices they report associated to retrieving, preserving, and delivering organs, with final cost coming from Medicare or transplant facilities (which in flip cost Medicare and different insurers). This technique, critics have lengthy charged, doesn’t present sufficient incentive to acquire harder-to-retrieve organs from sufferers who could also be older or have sure medical circumstances.
To get OPOs to gather extra organs, the Trump administration in 2019 issued an government order calling for brand spanking new guidelines governing how the organizations are licensed by the federal authorities, guidelines that have been finalized two years later. This was excessive stakes: If an OPO loses certification, it has to close down, and one other OPO will get its territory. The principles have been meant to extra strictly grade OPOs on the share of organs they ultimately transplant than the sooner, laxer guidelines did.
However there was a catch. Along with organs recovered from deceased donors and transplanted, pancreata recovered and used for analysis would rely towards recertification as properly. Not every other organs for analysis — simply pancreata.
What occurred subsequent may be see within the chart above: a large, sudden surge within the variety of analysis pancreata being recovered by OPOs, starting in 2022, the exact yr the brand new analysis system took impact.
I’ve lengthy been fascinated by this development, which OPO critics name the “pancreas loophole” and OPO defenders describe as a superbly authorized response to overly onerous rules. The numbers characterize 1000’s of actual, bodily human pancreata, taken from actual, not too long ago deceased donors, that wouldn’t have been taken from these our bodies with out this regulation.
I’ve tried in latest months to make sense of how this occurred, and what it means. I’m not the one one; the Senate Finance Committee has been investigating, and launched a report in early June on the issue.
There’s nonetheless lots that is still unknown in regards to the destiny of those pancreata (when you work at an OPO or analysis middle and know extra particulars, please electronic mail me). However what is obvious is that they characterize an strategy by the federal authorities towards rising organ provide that completely nobody is proud of. If the purpose of the rules is to assist individuals in want — together with the tens of millions of People with diabetes, a illness of the pancreas — evaluating OPOs primarily based on the variety of pancreata they donate to researchers merely doesn’t make any sense.
However to grasp how we began judging them this manner regardless, it’s important to go all the way in which again to an obscure regulation handed in George W. Bush’s first time period.
Pancreata (and why you may want one transplanted), defined
Everybody is aware of, in broad strokes, what the guts or the lungs do. However the pancreas doesn’t have the identical degree of fame. Its fundamental objective is to excrete enzymes, hormones, and different compounds to each 1) assist the physique digest meals and a pair of) regulate blood sugar ranges.
The latter perform is carried out by the islets of Langerhans, cells within the pancreas (named after their discoverer, Nineteenth-century German researcher Paul Langerhans) that secrete two totally different hormones: insulin (to decrease blood sugar) and glucagon (to boost it).
In Sort 1 diabetes, the flexibility of the pancreas to supply insulin is impaired and thus blood sugar ranges are dangerously elevated; in some sorts of Sort 2 diabetes, the physique develops resistance to insulin’s results. Sometimes, individuals with diabetes take care of this by means of injecting insulin straight, a course of that has grow to be far more refined in latest a long time as finger pricks and needles have given strategy to insulin pumps that may straight measure and modify blood sugar ranges.
However even with superior care, diabetes carries lifelong medical penalties, so researchers have lengthy sought a extra everlasting repair: What when you may substitute or complement the defective islet cells in sufferers with diabetes with wholesome islet cells? May you, then, treatment diabetes on the supply and keep away from the necessity for insulin injections and the chance of long-term well being results altogether?
In essentially the most excessive model of this strategy, a whole new pancreas is transplanted right into a affected person with diabetes, like swapping out a defective half. It is a confirmed remedy (915 occurred in 2023) and when completed it really works properly, primarily curing the recipient’s diabetes.
However there are main downsides: it’s important to undertake main stomach surgical procedure with a small however actual probability of failure, and if that succeeds, it’s important to stay on immunosuppressant medication for the remainder of your life to forestall organ rejection.
For that purpose, physicians usually rule that the prices of a pancreas transplant outweigh the advantages for most individuals with diabetes. Dwelling with an insulin pump is healthier than risking surgical procedure and having a completely compromised immune system. Only a few of the 38 million People dwelling with diabetes, then, are going to be candidates for a pancreas transplant.
This math adjustments, nevertheless, if the affected person in query additionally wants a kidney transplant. Diabetes accounts for almost half of all new circumstances of kidney failure, so the next share of individuals with diabetes than individuals with out discover themselves on this state of affairs. In these circumstances, because the affected person is already going to have surgical procedure and be on immunosuppressants, throwing in a brand new pancreas to the surgical procedure and curing their diabetes in the identical operation that cures their kidney failure begins to seem like a horny choice. That’s why nearly nobody will get a pancreas transplant within the US with out getting a kidney transplant too.

For many years, researchers looking for efficient diabetes therapies have experimented with an strategy known as islet cell transplantation.
Somewhat than transplant the entire pancreas, the process merely transplants insulin- and glucagon-producing islet cells into the recipient’s liver. It’s far much less invasive, and may be completed with native anesthesia and with out an in a single day hospital keep (although, skeptics argue, usually much less efficient than complete pancreas transplantation too). If the islet cells come from a deceased donor, it does imply a lifetime of immunosuppression, however in “autograft” procedures, which use a subset of still-healthy islets from one’s personal impaired pancreas, immunosuppression isn’t obligatory.
Islet cell transplantation, although, stays little-used and largely experimental within the US. A part of the rationale why is regulatory: Whereas pancreases are legally “organs,” and due to this fact excluded from regulation by the Meals and Drug Administration, the FDA has asserted its authority to additionally regulate islet cells as human tissues and to require premarket approval earlier than they are often transplanted right into a affected person, similar to a drug would.
To realize such approval, it could be essential to conduct scientific research to exhibit that the islet cells are “secure and efficient”; as soon as authorised they’d have to be produced in compliance with “good manufacturing practices.” To obtain islet cells not authorised by FDA, a affected person would wish to hitch a scientific examine (if one is being performed) or go to a rustic (together with Canada, Australia, and several other EU and Asian international locations) with totally different rules.
FDA’s necessities have unsurprisingly slowed the islet cell transplant discipline down. The newest knowledge comes from 2021, when solely 10 such procedures have been carried out within the US. In 2012, 111 have been carried out, however the quantity has steadily fallen ever since. It’s orders of magnitude rarer than a whole-pancreas transplant.
However islet cell transplants have some champions, together with politicians. In 2004, Congress handed, and George W. Bush signed, the Pancreatic Islet Cell Transplantation Act. It was sponsored by Rep. George Nethercutt Jr. (R-WA), who mentioned he was pushed by his daughter’s diabetes to attempt to develop entry to islet cell transplants so sufferers may “reside with out being depending on insulin injections.”
Nethercutt’s invoice sought to hurry up analysis progress by, amongst different measures, guaranteeing ample provide of pancreata for scientists. The regulation features a provision stating, “Pancreata procured by an organ procurement group and used for islet cell transplantation or analysis shall be counted for functions of certification or recertification.”
That meant that when regulators in 2019 have been reconfiguring certification guidelines for OPOs to encourage them to impact extra transplants, they needed to embody a carve-out for pancreata used for islet cell analysis. The carve-out existed from the very first draft proposal that Trump’s Facilities for Medicare and Medicaid Companies (CMS) launched, and stayed into the remaining rule in 2021.
The mysterious pancreas growth
That rule’s adjustments utilized for evaluations of organ procurement organizations beginning in August 2022. Within the years 2018 by means of 2021, OPOs collected round 500–600 pancreata for analysis every year. In 2022, that determine was 1,432, a three-fold improve. In 2024, the quantity hit 2,053. The impact of the brand new regulation was clear.
It’s essential to notice that there are not any indications that the pancreata being collected by OPOs for analysis are slicing into the provision of pancreata for donation. The share of lifeless individuals whose pancreata are appropriate for transplant is extremely low, due to the exacting requirements for donor age and well being.
“Solely a sure variety of donors are going to be younger sufficient (most likely lower than 50, possibly lower than 45) and lean sufficient (possibly lower than 30 BMI, most likely lower than 27 or 28),” Jonathan Fridell, a transplant surgeon and director of the pancreas transplant program at IU Well being in Indianapolis, advised me. “We’re nonetheless going to have a look at the individuals which can be older, nonetheless take a look at the individuals which can be heavier, however the chance that they’re going to have a transplantable pancreas is decrease.” There are thus loads of non-transplantable pancreata left over that could possibly be used for analysis as soon as the prime ones are taken away for surgical procedure.
The issue with the surge in analysis pancreata, then, isn’t that it’s taking pancreata away from recipients who want them. It’s subtler than that. By racking up massive numbers of pancreata for analysis, OPOs are enhancing the grades they obtain from federal regulators, and avoiding the chance of dropping certification and having to show over territory to a different OPO. This grading and decertification course of was meant to incentivize OPOs to gather extra organs for transplant, particularly kidneys, that are each simpler to transplant than pancreata and extra desperately wanted. However the analysis pancreata present a manner round that incentive.
Calculate the grades that OPOs would get with out these pancreata versus those they’re getting now, and also you’ll discover the outcomes are radically totally different.
CMS classifies OPOs into three tiers: 1, 2, and three, with tier 3 OPOs dealing with decertification. Utilizing knowledge obtained from the organ procurement transplant community, we’re capable of calculate which tier every OPO can be in with and with out their analysis pancreata primarily based on their efficiency in 2023. The yr that’s really binding for OPOs and determines whether or not they are going to be decertification is 2024, for which knowledge doesn’t but exist, however the 2023 knowledge offers us some indication of which OPOs are utilizing pancreata to save lots of themselves.
For 2 OPOs, together with analysis pancreata meant they went from tier 3, which might end in decertification, to tier 2: Donor Community of Arizona, which covers that complete state; and OneLegacy, which incorporates most of Southern California together with Los Angeles and Orange counties. One other, Kentucky Organ Donor Associates, went from tier 2, the place it may face strain to enhance efficiency, to tier 1, suggesting it excels.
These are usually not small establishments. OneLegacy is by far the most important OPO within the nation by quantity of organs collected and inhabitants coated. Its CEO, Prasad Garimella, earned $1.1 million in whole compensation in 2023, the final yr for which public IRS filings can be found. It stood an actual probability of being decertified if it didn’t meet the brand new organ assortment requirements. And it went from reporting 83 pancreata collected for analysis in 2021 to 441 in 2022 and 492 in 2023. An over fivefold improve, in a single yr — and no marvel, given its existence was at stake.
(In response to a request for remark, OneLegacy acknowledged, “When recovering organs for transplant, OneLegacy will allocate pancreata to respected islet cell analysis companies provided that they aren’t viable for transplant into sufferers. Over 99.6% of pancreata recovered by OneLegacy for analysis between 2018-2022 have been allotted to 2 Nationwide Institute of Diabetes and Digestive and Kidney Illnesses (NIH-NIDDK) laboratories.”)
Once more, the 2023 knowledge will not be binding. The 2024 knowledge can be. However until one thing adjustments with the way in which the federal government evaluates these pancreata, some main OPOs will keep away from dire penalties for the only purpose that they began accumulating a whole lot of pancreata for analysis.
The place did all of the pancreata go?
The rise is so clearly a results of the brand new guidelines that OPOs don’t even hassle to disclaim it. Responding to the Senate report earlier this month, the Affiliation of Organ Procurement Organizations, which lobbies for the teams and in opposition to the CMS’s stricter guidelines, mentioned merely, “At present, pancreata recovered for analysis stay a part of the efficiency analysis metrics, and OPOs have operated in accordance with the rule.” In different phrases: yeah, we discovered a loophole. And what are you going to do about it?
It’s an perspective that has pervaded the trade because the loophole got here to gentle. In a listserv thread discussing the brand new guidelines, leaked to the Senate Finance Committee, an OPO worker wrote, “You probably have a donor with solely a pancreas for analysis, that’s an organ donor for the Donor Price. In any other case, a donor is any donor with not less than 1 organ transplanted. Savvy (or cynical?) OPOs ought to start out a pancreas for analysis program instantly.”
However there’s a query that is still unanswered: The place did all these 1000’s of pancreata go?
It’s clear that the overwhelming majority of analysis pancreata didn’t go into islet transplants. We’re speaking about 1000’s of organs, not the few dozen that plausibly may have been transplanted as a part of islet procedures up to now couple of years.
Certainly, OPOs have admitted as a lot. The Facilities for Medicare and Medicaid Companies asks OPOs for knowledge on organs recovered yearly, and in August 2024 clarified that it could solely rely pancreata as “‘used’ for analysis if they’re accepted to be used in bona fide islet cell analysis performed by a professional researcher, corresponding to analysis authorised by the Nationwide Institutes of Well being.” It then requested OPOs to resubmit their knowledge, clarifying which organs have been for islet cell analysis particularly.
As soon as they did, the variety of reported pancreata fell dramatically:
In 2023, the whole went from 3,338 pancreata earlier than the steering, to 1,812 after, a drop of 46 %. Some OPOs, like Legacy of Hope in Alabama, now reported zero pancreata for analysis; earlier than the steering narrowed qualifying functions, Legacy of Hope had claimed 226 pancreata.
However even after the change in steering, we’re left with smaller numbers which can be nonetheless a lot too large to be defined by bona fide islet cell transplants. There merely weren’t 1,812 islet cell transplants within the US in 2023, however there have been 1,812 pancreata credited as donated for islet cell analysis. And that quantity continues to be over triple the quantity claimed in 2021, which means the rise sparked by the brand new OPO guidelines largely stays even after the federal government’s clarification. Analysis by David Goldberg, Erin Tewksbury, and Matthew Wadsworth has proven that the variety of pancreata reported as recovered by OPOs additionally swamps the quantity that the Built-in Islet Distribution Program (IIDP), a consortium that collects and extracts islet cells from pancreata, reviews receiving from these OPOs.
One of many factors of the Senate investigation was to find out the place precisely these pancreata went. The Senate Finance Committee, with the good thing about subpoena energy, went about asking main OPOs for what precise objective the analysis pancreata have been used. The principle reply they acquired was “we don’t know.”
“Most of the OPOs acknowledged that it’s the accountability of the analysis services or establishments receiving the pancreata to tell the OPOs on the aim, strategies, and efficacy of the analysis being performed on the pancreata and different organs that OPOs provide,” the report states. In different phrases, OPOs themselves don’t hold monitor. “Many of those OPOs,” the report continues, “have despatched pancreata to biobanks and different establishments or services that maintain pancreata for an unknown interval for use for functions that could be undefined or nonexistent.”
Put one other manner: These pancreata may, for all of the OPOs or the Senate is aware of, be sitting on a freezer someplace, not transplanted into anybody. Or possibly not even sitting there in any respect. Greg Segal, an activist advocating for reform to the pancreas loophole, testified earlier than a Home committee that workers at one OPO, joked “that they’re conducting analysis on the efficacy of rubbish disposal A versus rubbish disposal B” when disposing of pancreata.
All through all this, OPOs have had one constant message: They’ve complied with the regulation, as they see it.
“Pancreata recovered for analysis stay a part of the efficiency analysis metrics, and OPOs have operated in accordance with the rule,” the Affiliation of Organ Procurement Organizations, the teams’ lobbying store in Washington, mentioned in its assertion after the Senate investigation was launched. “When CMS issued clarifying steering in 2024 limiting this metric to pancreata used for islet cell analysis, OPOs responded instantly and labored with the company to validate knowledge and guarantee compliance.”
Jedd Lewis, CEO of the Organ Preservation Alliance and a longtime veteran of the transplant discipline, notes that CMS’s rule uncared for to outline what it means to make use of a pancreas for analysis, regardless of many OPOs and trade specialists particularly flagging the issue for CMS earlier than that rule took impact. And CMS’s new steering final yr did little to unravel the issue, he argues.
“Final years’ memos merely recognized the scope of pancreas donations that OPOs can be judged on as these for ‘islet cell analysis.’ However CMS didn’t outline what that really means …and on its face it’s an enormous scope of analysis,” Lewis wrote in an electronic mail. “There are such a lot of … ways in which researchers are how these cells perform: learning the pancreas complete, slicing it into skinny sections, isolating the person islet cells, even breaking the cells into the element components.” That’s all useful analysis, he argues, and clearly pertains to islet cells, even when the pancreata are by no means really utilized in islet cell transplants.
Wadsworth, a coauthor on the examine discovering a surge in analysis pancreata and CEO of the LifeConnection OPO in northwest Ohio, concedes that counting pancreata that didn’t produce islet cells for transplant might technically be authorized. However he nonetheless thinks it’s improper.
“I labored with this surgeon early on in my profession who mentioned ‘simply because you are able to do one thing doesn’t imply you need to,’ Wadsworth famous. “Primarily based on what’s written, possibly they didn’t do something improper, however you don’t must look far again in historical past to seek out examples the place one thing wasn’t unlawful, nevertheless it undoubtedly wasn’t proper both.”
LifeConnection, Wadsworth says, was capable of adjust to the spirit of the CMS rules by discovering counties in its jurisdiction the place low numbers of organs have been being procured, and dealing on fixing the issue hospital-by-hospital. It’s more durable than simply harvesting pancreata, nevertheless it means organs get transplanted to individuals who want them.
One irony of the controversy is that almost all OPOs, and their representatives, don’t imagine that analysis pancreata ought to rely for his or her evaluations. “AOPO has considerations about together with pancreata utilized for analysis within the knowledge used to calculate the numerator of both proposed measure,” the Affiliation of Organ Procurement Organizations wrote in an early 2020 remark because the rules have been being developed. “The utilization of pancreata for analysis is pushed by demand of native researchers. Inclusion of pancreata for analysis within the knowledge utilized for the numerator might skew comparisons of OPOs in that class and probably result in inaccurate conclusions.”
However each the OPOs and their regulator, CMS, have been sure by the 2004 regulation requiring that analysis pancreata, not less than that for islet cell analysis, should rely for these evaluations.
We’re working out of time to repair this downside. If nothing adjustments, OPOs can be evaluated on the premise of information they’ve submitted now, together with a whole lot of pancreata that have been by no means used for islet cell transplants. Whether or not you assume that displays OPOs complying in good religion, or subverting the system, it’s not a coverage anybody ought to assume makes a lot sense.
CMS has some capability to behave right here — however maybe the most effective repair would come from Congress within the type of a authorized provision clarifying the 2004 act. Merely repealing the availability proscribing how OPOs may be evaluated can be easiest — however even higher can be pairing it with a authorized change that might assist islet transplantation analysis excess of the 2004 has so far.
Recall that islet transplants presently don’t rely as organ transplants within the US. They rely as therapies with organic tissue ““If islet cells are solely organs, as a result of they’re a subpart of the pancreas, which is an organ underneath transplant regulation, then the FDA mustn’t have jurisdiction,” Gail Javitt, a veteran lawyer engaged on FDA regulatory points on the agency Hyman, Phelps & McNamara, advised me. “Nevertheless, FDA has taken a distinct place, that islet cells are a mobile remedy and should endure premarket approval similar to a drug would.” If you wish to use it for remedy of a affected person, it’s important to undergo them. That has had the sensible affect of slowing down the provision of islet cells for transplantation on this nation.”
Legally clarifying that islet cells are organs, not mobile therapies, and that they’re excluded from FDA oversight then, may go an extended strategy to selling the remedy. Final Congress, Sen. Mike Lee (R-UT) and Rep. Matthew Rosendale (R-MT) every launched payments making this transformation, with solely Republican co-sponsors.
However this needn’t be a partisan challenge in any respect, and when you paired this provision with a repeal of the 2004 regulation allowing OPOs to rely pancreata for analysis as a part of its transplant metrics, you possibly can arrive at a near very best system. OPOs can be evaluated on their capability to transplant islet cells, as a result of they’d be organs like every other. They might not be capable to get greater scores by recovering pancreata for analysis that may simply languish on a shelf.
This does require Congress to make a small change. However it’s a small change that ought to be principally uncontroversial. There’s nothing for many OPOs or for advocates attempting to maximise donations to dislike right here, and there’s tons for islet cell researchers to like. It’s a small repair that might go a really good distance.
