Will an opt-out organ transplant law save lives?

The recent decision in England to change the organ donation law from voluntary consent (opt-in) to presumed consent (opt-out) highlighted the debate around the best approach to organ donation. It is hardly new. Christian Barnard’s first human heart transplant in 1967 was the catalyst for many countries to examine what legal changes were needed to realize the full potential of transplantation.

Fifty years ago, we were actively involved in drafting the Uniform Anatomical Gift Act (UAGA) with the National Conference of Commissioners on Uniform State Laws in the United States. The model law, which is based on the principles of consent and making a gift, was completed in 1968 and adopted by all 50 states in three years. The UAGA is founded on three core ethical principles: altruism; individual autonomy; and public trust. For fifty years, it has provided and continues to provide a sound and stable legal platform on which to build a nationwide organ donation system. [1]

The rapid adoption of the UAGA can be explained by the fact that it is a gift statuteno one is required to be an organ donor or to authorize the organ removal from their recently deceased next of kin. [2] Presumed consent was considered when the act was drafted and on several subsequent occasions and has always been dismissed in the US. [3]

The total number of American adults who are registered organ donors has steadily increased to over 55% of the eligible population. More registered donors have resulted in more organ transplants annually over each of the past five years. While there is wide variation among the 58 regional Organ Procurement Organizations (OPO) in the US, the top performers have donation rates that are better than or comparable to all opt-out countries, including Spain. For example, a leading American OPO, covering over 11 million people, has a donor/million rate of over 50, compared to Spain at 46.9 in 2017At the same time, the number of candidates on transplant waiting lists continues to grow, in part due to the epidemic increase in obesity and diabetes, which leads to kidney failure and more individuals on dialysis who are waiting for a kidney transplant.

In the hope of increasing the number of transplants, several countries, such as France and Germany, have enacted “opt-out” systems over the years. The government in England recently announced that an opt-out law will be in place by 2020, if parliament approves it. Some believe that this legal change will yield more transplants. There is no convincing data to support this opinion, however. 

Spain is often cited as having the world’s highest nationwide transplant rates and they have an opt-out law. But, upon careful examination, their success is based on other factors. Spain’s law was enacted in 1979, but there was no measurable impact on transplant rates until after 1989, when a strong national organization was established, and significant resources were committed to provide support for highly trained intensive care physicians and nurses in transplant centers. Rafael Matesanz, the director of the Spanish programme since 1989, attributes Spain’s higher organ donation rate to the practice of these highly qualified physicians and nurses who always have a conversation with donors’ families to secure their approval before proceeding with organ removal. [4] While Spain has a legal opt-out system, it functions as an opt-in system, because the family is routinely asked for permission. Wales shifted to an opt-out law in 2015, but the number of organ donations has not increased, over the past two years.

In England, a private members’ bill, which would require people to “opt out” if they do not want their organs used, passed its second reading in February 2018 and is scheduled to be discussed again in the House of Commons. England has already made significant progress in donation by building on the Second Organ Donation Task Force Report in 2008, which included important commitments to enhanced clinical practice and public awareness. Organ donation numbers have increased by an impressive 70% since that time. [5] 

Organ donation is an intensely personal gift. Receiving an organ is a medical miracle based on the altruism of another, usually an anonymous person or family. Losing a life because of the lack of an available organ is a tragedy. It is tempting for leaders to recommend a change in the law based on bold promises of saving lives. Unfortunately, changing the law alone, is an illusion that creates false hope. It diverts attention from investing in actions that have been demonstrated to increase transplantation rates as described above. Further, “opting out” runs the risk of undermining public trust by overriding individual autonomy and could undermine confidence in the NHS and the current system. 

Instead of changing the law, we recommend enhanced efforts to actively encourage individuals to register as donors and discuss their wishes with their families, as well as increased investments in the training of physicians, nurses, and others who will be having conversations with families about donation. At a time when public confidence and trust in our governments has declined, maintaining trust by respecting individual autonomy and family wishes is vital. We believe lives can be saved through strong, committed, collaborative leadership, and not by changing to an opt-out law that, by itself, has not been shown to be effective in other countries.
