Organ distribution
Liver and intestine policy
Making allocation more fair and flexible
Making liver distribution fair and equitable
With more than 10,000 people waiting for a lifesaving liver transplant, ensuring equitable liver allocation is a priority for the entire donation and transplant community. Liver distribution policy makes the system work efficiently and fairly for all transplant patients regardless of where they live, what hospital they choose for their care, or how sick they must be before they are likely to get a transplant.
Since the current liver and intestine policy took effect in 2020, liver transplants have increased by 4.3 percent. This policy prioritizes the medical urgency of liver transplant candidates in relation to the distance between the donor hospital and transplant hospital. Patients who are both most in need and closest to the donor get offers first.
But liver and intestine policy is still undergoing transformation — learn about continuous distribution, the future state of liver and intestine allocation.
