Every year, thousands of Americans facing liver failure try to get new organs. Many of these are successful. But some experiences with the liver transplant process go wrong. The chances of success often depend on which hospital replaces your liver, according to data from the Scientific Registry of Transplant Recipients.

Problems with liver transplants can occur before a transplant, during surgery or after the procedure. Medical experts said that issues might stem from failing to document that a donor’s blood type is compatible with the recipient or medical errors during surgery. There is also evidence that a disproportionate number of people of color do not get the help they need. We hope this questionnaire can help us make a more complete list of when, how and why problems occur.

We want to speak with patients who have faced adverse outcomes, as well as family members who lost loved ones to the medical process. We also want to speak with medical providers or regulators familiar with the process to better understand how it works.
