Review boards
Review board members quickly review specific, urgent-status patient registrations on the OPTN heart, liver and lung transplant waiting lists. Review board members collectively determine whether these listings are appropriate, based entirely on clinical information that complies with OPTN policies. Separate boards review exceptions for each organ.
For complete review board member lists, please contact UNOS Customer Service at 800-978-4334.
