The United Network for Organ Sharing (UNOS) is a non-profit organization that oversees national transplant waiting lists, collects data about every organ transplant that occurs in the United States, promotes awareness about the importance of organ donation, and “matches” donors to recipients based on expected benefit, waiting time, geography, blood/tissue type, etc.

In late 2018, UNOS revised the criteria for adult heart allocation based on a patient’s medical urgency status. Gone are the days of “status 1a.” Here’s a small table I put together outlining the new criteria.
Tag a friend interested in cardiac surgery or organ transplantation, let me know if you’ve seen these done, and drop me a comment with questions!
