All UNetSM users who complete OPTN data collection forms
January 15, 2019; quarterly updates
A cross-functional team of UNOS staff and OPTN members is working on a data governance initiative to improve the consistency and quality of OPTN data collection. The first set of data definitions using a new format are published in UNet online Help as of January 15, 2019.
We will 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.

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.
