Every year, thousands of Americans facing organ failure try to get a transplant. Many of these are successful. But some experiences with the process of getting a new organ — including kidneys, livers, hearts and lungs — go wrong. The rates of success differ depending on which hospital replaces your organ, according to data from the Scientific Registry of Transplant Recipients.

Problems with organ 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. When problems do occur within a transplant center, the process to investigate what went wrong is often confidential, making it hard to tell if that center has addressed the safety risks for patients.

We want to speak with transplant recipients who have experienced problems with their treatment, as well as family members who lost loved ones as a result of a transplant. We also want to speak with medical providers or regulators familiar with the process to better understand how safety problems within transplant centers are investigated.
