What does UNOS maintain for solid organ transplants?

The correct answer reflects the modern approach to managing waitlists for solid organ transplants. UNOS, or the United Network for Organ Sharing, utilizes a computerized system to maintain accurate and up-to-date information on patients waiting for transplants. This digital system allows for efficient tracking of donor organs and recipient status, ensuring that matches are made based on medical need, compatibility, and urgency. The use of computerized waitlists enhances transparency and accessibility of data, facilitating timely decision-making and potentially saving lives.

In contrast, options such as paper waitlists, manual records, or local registry databases do not provide the same level of efficiency, accuracy, or comprehensive data management. These methods could lead to delays and errors in organ allocation, which is critical in the context of transplant medicine where timing can be the difference between life and death. Therefore, the computerized waitlist system that UNOS utilizes serves as the backbone of transplantation logistics, ensuring that patients receive the best possible chance for successful organ transplant outcomes.
