US National OCS Liver Perfusion (OLP) Registry is a study to collect information on liver transplants. It is looking at two types of liver preservation methods: OCS liver perfusion and other ways of keeping the liver healthy before it is transplanted. This is an observational study, which means it only collects data and does not provide any treatment. The study is run by TransMedics and they work with UNOS, the organization that manages organ transplants in the U.S., to gather data. Using this data, researchers want to better understand how different liver preservation methods affect transplant outcomes.

• Anyone who receives a liver transplant is eligible to be part of this study.
• This study does not involve any visits or treatment changes as it only collects information.
• There is no direct compensation, but you help improve future liver transplant outcomes.
