title: MELD/PELD: one year later.
abstract: The liver allocation policy in the United States was changed on February 27, 2002, to a continuous scale with almost no weight given to time waiting on the list. This was based on the dissatisfaction with the old categorical system and an understanding that waiting time as not a good discriminator of medical urgency. To assess the effects of this change, liver allocation results for the first 6 months of this new system (February 27, 2002, to August 30, 2002, era 2) with the corresponding 6 month period 1 year earlier (February 27, 2001, to August 30, 2001, era 1) were compared. Fewer registrations on the waiting list, fewer removals from the waiting list because of death or "too sick," and an increase in the number of cadaveric transplants under the new system were observed. Patients with hepatocellular cancer received additional priority with the new policy and there was a significant increase in the number of candidates transplanted with this diagnosis in era 2. Early posttransplant patient survival has not changed under the new system. Although there are many areas for improvement, which will be addressed in future refinements, the new US liver allocation plan has provided a more objective, patient-specific system to better rank waiting liver transplant candidates.
