Two new data elements added to transplant program Center STAR files, available March 7

Two new data elements added to transplant program Center STAR files, available March 7

Transplant hospital Center STAR files contain datasets of information related to waiting list registrations and transplants. UNOS creates the file based on data every hospital enters into Waitlist℠ and TIEDI® applications as well as additional data elements collected from organ procurement organizations (OPOs) and histocompatibility labs. UNOS also includes patient deaths reported from other sources.

Based on requests from transplant professionals and items identified by UNOS research staff, UNOS has added COVID information for Donor and Match ID to the Center STAR files.

  • The updated data files that reflect this change will be available on March 7, 2022
  • Updated corresponding file layouts are available as of Feb. 7

Users should adjust any automated process used to import these files.


New data elements that will be added to the transplant/waitlist files for all organ types:

  • MATCH_ID (NUM): ID number of organ match run resulting in transplant
  • COVID_POS_DON (CHAR(1)): Donor tested positive for COVID

In all cases, these new fields are the last columns in the layout.
