When Steve Jobs needed a liver transplant in 2009, he went to
Tennessee, where the wait time for a donated organ is significantly
shorter than in states like California, Massachusetts, Texas, and New
York.
He didn't break any rules; he just took advantage of an antiquated
system that distributes organs along arbitrary regional lines that were
developed more than 30 years ago.
As a result, where patients live has a disproportionate effect on their
opportunity to receive an organ, and consequently, on their risk of
dying while on the waiting list.
The harsh reality is that, wherever you live, there aren't enough
organs to accommodate those in need. Nationally, about 8% of patients
die while waiting for a liver; in New York, that rate is nearly double.

In any given year, about 6,000 livers from deceased donors are
available for transplantation nationwide. (In the case of liver
transplant, it is also possible to take part of a living donor's organ,
but this option is underutilized — only 359 living-donor transplants
were done in 2015.)
Because more than 24,000 Americans are waiting for a liver transplant,
that leaves about 18,000 people on the waiting list for a donor organ —
and roughly one in 10 of those patients lives in New York State. Many of
us in the transplant community are working to come up with a more
equitable system.
The liver is a critical organ, responsible for hundreds of functions,
many of them related to digestion and metabolism. One of the liver's
most remarkable features is that it can fix itself and actually
regenerate.
However, that self-healing ability isn't infinite. With continuous
damage, the liver starts to form scar tissue which eventually leads to
cirrhosis and end-stage liver disease. These are the main indications
for liver transplantation.
What causes liver damage in the first place? Many of the causes fall
into broad categories, including viral hepatitis; drug-induced liver
injury; or cholestatic diseases.
Fatty liver disease and alcohol use are also major causes of liver
damage, and both are on the rise. Liver cancer that is unresectable —
too extensive to be removed surgically — is also a major indication for
transplantation.
Patients in need of liver transplantation are often quite ill. They can
appear yellow, with jaundice, and they can also have dramatic abdominal
fluid retention, gastrointestinal bleeding, and encephalopathy, a
condition marked by confusion and forgetfulness.
Liver transplantation has achieved very good outcomes. At Mount Sinai,
almost 90% of transplant patients are alive at the one-year mark, and
75% reach the three-year mark. These are patients who were so sick that
they had almost no chance of surviving a year without receiving a new
liver.
Most liver transplant patients stay in the hospital for seven to 10
days, and within six weeks, they are back to doing what they want —
quite literally. After transplant, people have even played professional
sports or competed in the Olympics. Getting a new liver can restore
patients to an active and productive life. But the question remains: How
do you decide who gets these scarce, life-saving resources?
Following instructions from Congress, the Institute of Medicine studied
the question of organ allocation and determined that for livers, the
sickest patients should have more priority.
As a result, researchers developed a disease-severity score known as
the Model for End-Stage Liver Disease (MELD), which is calculated from
three lab tests, including bilirubin, clotting time (called INR), and
creatinine.
A healthy person might have a MELD score of about 6, but someone in
need of a liver transplant should have a score above 15. While a New
Yorker might need a MELD score of 35 to 40 in order to get a transplant,
that same person, if she lived in other parts of the country, might be
able to get a transplant with a MELD score of 25 or even lower.
In part, this is because liver diseases are more prevalent in urban
areas. Moreover, some states have higher rates of strokes and
preventable deaths, the causes of death that provide most donor organs.
In addition, some areas of the country have improved their donation
rates, while other areas have made less progress.
Clinicians and public policy experts generally agree that socioeconomic
status, race, gender, and where you live should not determine your
access to transplant. But as an unintended consequence of the current
system, where you live is one of the biggest factors in how long you
wait for a transplant — or if you ever get one.
This is now recognized as an inequity by the United Network for Organ
Sharing (UNOS) and the Health Resources and Services Administration, the
federal agency in charge of overseeing organ donation and
transplantation.
While the geographic inequity is clear, a solution remains elusive.
Several models for distributing organs are now being considered. Because
the current system was designed for purely administrative purposes, not
equitable liver distribution, it has been outperformed by nearly every
model that has been tested.
Central to the debate is whether a donated liver is considered a local
or national resource. When polled, donor families routinely state that
they want their loved one's liver to go to the person most in need. In
my mind, donated organs should be a national resource. Having the means
to travel to another state should not determine a patient's life or
death.
To become more informed about liver disease and transplantation, check the web sites of UNOS (www.unos.org), the American Liver Foundation (liverfoundation.org), and the Mount Sinai Health System (mountsinai.org/patient-care/service-areas/organ-transplants).
Living with liver disease is not easy, but transplantation is all about
hope and the possibility of recapturing health and quality of life.
Thanks to donors, thousands of transplant patients are enjoying life —
and that is incredibly inspiring.
