Liver waiting list simulator Simple version

Two worlds, the same people and the same donor livers. Change something in world B.

Both worlds start as the UK is now. Whatever you change on the right is the only difference, so the gap between them is the effect of that change. A simulation from published UK figures, not real patients.

In world B the liver goes to whoever has waited longest. Three fewer people in every 100 are transplanted within a year and two more die or become too unwell, because the longest-waiting people are not always the people who most need a transplant now. The same people and the same livers were used in both worlds.
