Median MELD and PELD at transplant scores to be updated March 25
Published on: Sunday, March 8, 2020
As of Wednesday, March 25, 2020, updated median MELD at transplant (MMaT) and median PELD at transplant (MPaT) scores will be used as a basis for assigning exception scores for liver transplant candidates. The new scores are listed here for reference.
As of the effective date, if your transplant program’s MMaT score has changed as a result of the update, exception scores indexed to the MMaT will automatically be updated for all candidates. The score will also be adjusted in all current requests for new or extended exception scores. You should ensure candidates’ lab tests are current in case their calculated MELD score is now more comparable to their updated exception score.
The scores are recalculated every 180 days. They are based on a 365-day cohort of transplant recipients liver transplants performed within a radius of 250 nautical miles of each transplant program, with the following exclusions:
- Transplants of Status 1A and Status 1B candidates
- Transplants from living donors, cardiac death donors, and donors located more than 500 nautical miles from the recipient transplant hospital
Please note that your hospital’s MMaT may have changed to reflect differences in transplants performed within the past few months. For comparison, the scores in use until March 25 are available here.
The MPaT score is calculated from all transplant recipients in the cohort with a PELD score, age under 12 at time of transplant. This score remains at 35 and has not changed from the previous calculation.
