Allocation Process

Allocation Process | How Transplants Are Matched Fairly

What Is the Organ Allocation Process?

Think about the incredible kindness when someone says “yes” to organ donation. It’s a decision that offers a lifeline to someone else. But with so many people desperately needing a transplant, how does that amazing gift get to the person who needs it most? This is where the organ allocation process comes in.

It’s a pretty amazing system. At its core, it’s about making sure donated organs are matched fairly and quickly with the people who are the best fit and have the most urgent need. It’s designed to be impartial – meaning things like how famous someone is, how much money they have, or where they come from simply don’t factor in. What truly guides the decision is medical urgency, how well the organ matches the patient, and how close they are geographically (because organs can’t wait forever!).

To give everyone waiting for a transplant a real, fair shot at getting the organ that could save or dramatically improve their life. It’s all about making the biggest possible difference with each precious donation.

Who Oversees the Organ Matching Process?

Managing organ transplants across the entire country is a massive undertaking! Behind the scenes, a national organization called UNOS (the United Network for Organ Sharing) operates the system that determines how organs are matched and distributed nationwide. Think of them as the air traffic control for organ donation in the U.S. UNOS works under a federal contract as the administrator of the Organ Procurement and Transplantation Network (OPTN).

UNOS and the OPTN are the backbone of this life-saving effort. Here’s some of what they do:

  • They keep the National Transplant Waiting List: Imagine a single, constantly updated list with information about every patient in the U.S. waiting for an organ. That’s what UNOS manages. It’s called the organ transplant list.
  • They run the special matching computer system: They have a computer system (it’s actually called UNet) that uses complex algorithms. Basically, this system takes all the info about the donated organ and the patients on the waiting list and figures out the best potential matches based on the rules. This is the heart of the UNOS organ transplant matching process.
  • They set the rules: The policies for how organs are matched and shared are developed by expert committees. And guess who is on these committees? Not just doctors and scientists, but also patient advocates, donor families, and people with ethical and public health expertise. This mix of experience helps make sure the rules are medically sound, fair, and consider the real-life impact.

These policies aren’t set in stone—they get reviewed and updated regularly as medicine gets better and we learn more. It’s a system that keeps improving, always aiming to be as fair and effective as possible. This level of expertise and careful oversight is a big part of why the system is so trusted.

How Do They Actually Match Organs?

Every organ donation is a time-sensitive opportunity, and getting the match right is critical. The process considers several key criteria:

  • How Sick Is the Patient? (Medical Urgency): This is often the top priority. Patients who are the most critically ill and won’t survive much longer without a transplant are usually considered first. For livers, there’s a special score called the Model for End-Stage Liver Disease (MELD) score (or PELD for kids under 12). It uses lab results to figure out how sick someone is, and a higher score means a higher priority. 
  • Blood Type and Size Match: Just like needing the right blood type for a transfusion, the donor and recipient need compatible blood types. And the organ needs to fit! A donated lung or heart has to be the right size for the patient’s body to work properly. They look at donor height and weight to help figure this out. 
  • Geographic Location: Organs can only last for a short time outside the body – we’re talking hours, not days. Hearts and lungs are especially sensitive to time. Because of this, patients at transplant hospitals closer to where the donation happened are usually considered before those farther away. It’s a race against the clock to get the organ where it needs to be safely and quickly. 
  • Time on the Waitlist: If everything else is pretty equal (medical urgency, match, location), then the amount of time someone has been on the organ transplant list becomes a factor. This is a bigger deal for kidney transplants than for some other organs.

 

  • Tissue Type (HLA Matching): For some organs, especially kidneys and pancreases, matching certain tiny markers on cells called HLAs is really important. The better the HLA match between the donor and recipient, the less likely the recipient’s body is to reject the new organ. 

Your personal stuff – like your race, how much money you make, if you’re famous, your religion, or where you were born – never comes into play when they’re matching organs. The system uses only those medical and logistical factors to keep things fair for everyone.

What Role Does Donor Alliance Play?

While UNOS runs the national matching system, there are local teams across the country that do the crucial work on the ground. These are called Organ Procurement Organizations, or OPOs. Donor Alliance is the OPO that serves our communities right here in Colorado and most of Wyoming.

Donor Alliance doesn’t manage the national waiting list or run the matching system – that’s UNOS’s job. Donor Alliance is the bridge between the incredible gift of donation and the patient waiting for a second chance.

Here’s how Donor Alliance fits into the picture:

Coordinating the Donation Process

When a potential donor is identified in a hospital, the compassionate team at Donor Alliance is there. This includes working closely with hospital staff, guiding families through the decision-making process with compassion, and ensuring all necessary medical information is gathered to determine donation eligibility.

Entering Donor Information into the UNOS System

Once the donation is authorized, Donor Alliance collects detailed medical and clinical data from the donor. This information is then securely entered into the UNOS organ matching system, which uses it to find the most suitable recipients based on urgency, compatibility, and location.

Facilitating Matches and Transport

When UNOS finds potential matches, Donor Alliance coordinates everything needed for the organ recovery surgery and then arranges for the organ to get transported safely and quickly to the transplant hospital where the recipient is waiting.

Ensuring Ethical and Regulatory Compliance

Donor Alliance operates under strict federal rules and ethical guidelines. They are overseen by national health organizations to make sure everything is done correctly, respectfully, and transparently. This commitment to high standards is a big part of their expertise and the trust placed in them.

Supporting Donor Families

Beyond the medical side, Donor Alliance offers really important support to the families who have said yes to donation. They provide grief resources and ways to honor the donor’s memory, sometimes even helping families connect with recipients if everyone involved wants to. 

Why Does All This Matter? Because It’s About People!

It’s easy to talk about systems and criteria, but let’s not forget what this is really all about: people. Right now, over 100,000 people in the U.S. are waiting for a transplant. That’s a huge number of individuals, each with a life, a family, and a future they are hoping to see. And sadly, because the need is so great, we lose about 13 people every day who were waiting.

When an organ is matched and transplanted successfully, it’s a moment of pure impact. It means:

  • A second chance at life for someone with end-stage organ failure
  • A child going home from the hospital
  • A parent living long enough to see their child graduate

And it doesn’t stop at just one life. A single organ donor can save up to eight lives. When matched carefully and fairly, every transplant becomes a ripple of healing that touches families and communities.

Myth vs. Fact: Understanding the Truth About Allocation

There are some common misunderstandings out there about organ donation and how organs are allocated. Knowing the truth helps build confidence in the system:

  • Myth: If I’m a registered donor, doctors won’t try as hard to save my life.
    Fact: Totally false. The medical team working to save you in the hospital is completely separate from the transplant team. Their only focus is saving your life. Donation is only considered after every effort to save you has been unsuccessful and death has been determined. 
  • Myth: I’m too old or not healthy enough to be a donor.
    Fact: Not true! There’s no age cutoff for donation, and even people with health conditions can often donate. Medical experts evaluate every potential donor at the time of death to see what organs and tissues are healthy enough to be transplanted 
  • Myth: Rich or famous people get organs faster.
    Fact: Absolutely not. The system for matching organs is strictly based on medical need, how good the match is, how urgent the patient’s condition is, and geography. A person’s money, status, or who they are doesn’t play any role in the matching process. It’s fair for everyone on the list. 
  • Myth: My family gets to pick who receives my organs.
     Fact: To keep things fair and protect everyone’s privacy, the national computer system makes the match based on the medical criteria. Donor families provide authorization for donation, but they are not involved in choosing the recipients.

Understanding these facts helps build trust in a system that is carefully designed to be equitable and transparent.

Why Having Diverse Donors Really Matters

Our bodies are amazing, but they’re also really different. Besides blood type, there are other things, like tissue markers (called HLAs), that play a big role in how well a transplanted organ will be accepted by the recipient’s body. These markers are often similar among people from the same ethnic or racial background.

So, having a diverse group of registered organ donors is super important! It increases the chances that someone needing a transplant will find a compatible match, especially if they come from a background where certain tissue types are more common.

Here’s the challenge: Right now, people from diverse communities, particularly communities of color, make up a larger percentage of the waiting list than they do of registered donors.

Here’s Why That Matters:

  • Better Matches Mean Better Results:
    Especially for kidneys, a good HLA match can make a huge difference in how long the transplanted organ lasts and how healthy the recipient is. Since HLA types are inherited, finding a good match is often easier within your own ethnic group. 
  • Helping Reduce Waiting Times:
    Because there are fewer registered donors from some minority groups, patients from these communities unfortunately often have to wait longer to find a compatible organ. This isn’t fair, and it can seriously impact their health while they wait. For example, as of early 2025, Black/African Americans are a much larger percentage of the waiting list (27.8%) than they are of deceased donors (12.6% in 2024). This leads to longer waits for many. 
  • Increasing Donor Diversity Saves Lives:
    When more people from all communities, especially those currently underrepresented, register as donors, it helps balance the scales. A more diverse donor pool means a better chance of finding a match for everyone, which directly addresses health disparities in transplantation.

How You Can Help:

Your decision to register as an organ, eye, and tissue donor is incredibly powerful, no matter your background. And if you are part of a community that has faced these disparities, your decision is especially meaningful. You have the potential to be the perfect, life-saving match for someone who shares your heritage and is still hoping for their chance.

Ethics and Oversight: Built on Trust

Given that the organ allocation process involves such critical decisions, it’s absolutely built on a foundation of strong ethics and careful oversight. You need to be able to trust that the system is fair and operates with integrity.

Here’s what makes the system trustworthy:

  • Rules Made by Many Experts: The policies aren’t decided by just a few people. They’re developed and reviewed by those expert committees we talked about, including doctors, scientists, ethicists, and people who have actually been through the donation or transplant process. This wide range of experience and knowledge helps ensure the rules are fair, ethical, and truly work for people.
  • Respecting Your Choice: The system honors the decision of individuals who registered to be donors. If someone didn’t register, the family’s informed consent is required. Your personal wishes are respected.
  • Keeping Things Transparent and Accountable: The entire process is documented and watched over by federal health agencies. This means there are checks and balances to ensure policies are followed and everything is done correctly and ethically.

This strong framework, with its focus on ethical principles, expert input, and clear oversight, is why you can have confidence that the system honors the gift of donation and makes transplant decisions fairly.

Addressing Concerns and Building Confidence

It’s totally okay to have questions or feel a bit uncertain about organ donation and allocation. It’s a really personal topic. Donor families want to know their loved one’s generous gift is used wisely and with respect. Patients waiting need to trust that the system is honest and caring.

Here’s what you can be sure of:

  • Your background, your income, or whether you’re well-known will never affect your position on the waiting list or whether you get an organ offer.
  • Every single donated organ is matched using a national system designed to save as many lives as possible, based purely on medical need and compatibility.
  • The entire process is handled with the utmost care, dignity, and strict adherence to ethical standards.

If you or someone you care about is thinking about registering as a donor or is currently waiting for a transplant, please feel confident that the system is working hard to give everyone the very best possible chance.

The Takeaway: Hope, Healing, and Your Decision

The organ allocation process is more than just a medical or logistical puzzle. It’s a daily connection of incredible generosity and urgent need. It’s the system that makes possible the miracle of transplantation. And it works because it’s built on fairness, transparency, the expertise of so many dedicated people, and fundamental trust.

If you’ve already registered as an organ, eye, and tissue donor, honestly, thank you so much. It’s an amazing gift of hope. Please make sure to share your decision with your loved ones.  If you’re still thinking about it, that’s okay! Learn more, ask questions, and talk it over with your family. Your decision has the power to save and heal lives in incredible ways, and this careful system makes sure that generous gift goes exactly where it’s needed most.
