The US replaced organ-allocation maps with one continuous score across the country.
UNOS swapped rigid donation-service areas for a continuous, weighted point score so an organ's destination no longer hinged on where you lived.

那一手
Because organ allocation was carved into donation service areas and regions, a patient's access to a transplant could turn on where they happened to be listed, which is exactly what the federal Final Rule was written to forbid.
UNOS's continuous-distribution approach replaces those hard areas with a composite allocation score: all candidates are ranked nationwide by a weighted sum of medical, match and efficiency factors, then the organ is offered by that score.
The framework is built attribute by attribute, with the weights set through structured stakeholder exercises that compare each factor against the others, and proximity points are retained only to limit how far a viable organ has to travel.
为什么管用
- Hard geographic boundaries made access depend on place of listing
- A single weighted score captures medical and match factors together
- Structured pairwise comparison set transparent attribute weights
- Proximity points were kept only to manage transport and logistics
可以搬走什么
If a decision is distorted by an arbitrary line you control, delete the line and put everything on a single, weighted measure you can defend openly.
后来呢
The kidney and pancreas policies began continuous distribution in the 2020s, removing donation service areas and regions as units of allocation and shifting to a 250-nautical-mile circle plus the nation for proximity scoring, with other organ types following the same trajectory.
