Additions to the OPTN waiting list decreased in 2003 for all organs except kidney. On November 30, 2004 there were 95,598 registrations on the combined UNOS waiting list. Of these, 67% were awaiting kidney transplantation and 18% were awaiting liver transplantation. The majority of patients on the UNOS waiting list on November 30, 2004 were blood type O (51%), male (57%) and awaiting their first transplant (87%). Despite lengthy waiting times, the percentage transplanted within one year following listing increased over the past 3 years for all organs except heart and kidney. A substantial increase in the percentage of heart-lung candidates transplanted within one year was observed in 2003. Blood type and medical urgency had a significant impact upon percent transplanted within one year of listing for most organ types. Patients awaiting heart, liver, pancreas and intestine transplants had the highest probability of receiving a transplant within one year. Death rates have remained fairly stable over time; however, cause of death while waiting for a transplant varied with organ type. Death due to cardiovascular reasons was the most common cause of death for heart and kidney candidates who were on the UNOS waiting list, while multiple organ failure was the most common cause of death for liver and intestinal candidates who were on the UNOS waiting list.
2003年，除肾脏外，器官共享联合网络（OPTN）等待名单上的新增人数有所减少。2004年11月30日，联合器官分配系统（UNOS）等待名单上共有95,598例登记。其中，67%的人在等待肾脏移植，18%的人在等待肝脏移植。2004年11月30日在UNOS等待名单上的大多数患者血型为O型（51%），为男性（57%），且正在等待首次移植（87%）。尽管等待时间漫长，但除心脏和肾脏外，所有器官在登记后一年内接受移植的比例在过去三年中均有所增加。2003年观察到心肺移植候选人在一年内接受移植的比例大幅增加。血型和医疗紧急程度对大多数器官类型在登记后一年内接受移植的比例有重大影响。等待心脏、肝脏、胰腺和肠道移植的患者在一年内接受移植的可能性最高。死亡率长期以来一直相当稳定；然而，等待移植期间的死亡原因因器官类型而异。心血管原因导致的死亡是UNOS等待名单上心肾候选人最常见的死亡原因，而多器官衰竭是UNOS等待名单上肝肠候选人最常见的死亡原因。
