More details

We provide a list of revised definitions each quarter, to answer member questions about existing data fields and to clarify new requirements.This effort aims to provide clear, concise data definitions, improve quality of data, and provide transparency into changes. Clarifications are intended to provide guidance for future data entry; you are not required to amend data submitted before the collection date. The process to create revised data definitions includes reviews by multidisciplinary UNOS staff and the Data Advisory Committee.

Where to find the info in Help Documentation

Access Secure Enterprise and then choose TIEDI. On the menu, choose Help and click Online Help. Details can be found under Manage Data > History of Definition Changes. Field Definitions have also been updated to include each data element.

Background

The OPTN’s secure transplant information database contains all national data on the candidate waiting list, organ donation and matching, and transplantation. Organ transplant institutions use the system to match waiting candidates with donated organs. Institutions also rely on the database to manage time-sensitive, life-critical data, before and after their patients’ transplants.
