Debate on Organ Donation: Which System - Consent-Based or Presumed Consent - Is More Effective?
Organ Donation: The Opt-in vs. Opt-out Dilemma
Organ donation policies across the globe show a wide disparity. One question that continues to puzzle policymakers is whether an opt-in or opt-out system is more effective. Researchers from the UK have delved into this question by examining the organ donation protocols of 48 countries.
Under an opt-in system, individuals need to actively sign up to a registry to donate their organs post-mortem. In contrast, an opt-out system assumes that everyone consents to organ donation unless explicitly requested otherwise before death.
Prof. Eamonn Ferguson, the lead author from the University of Nottingham, acknowledges that the reliance on an active decision from individuals in both systems can lead to drawbacks:
"People may neglect to act for numerous reasons, including loss aversion, effort, and a belief that the policy makers have made the 'right' decision and one that they agree with."
However, inaction in an opt-in system can lead to false negatives, where individuals who would have been willing donors never donate. On the flip side, inaction in an opt-out system can potentially result in false positives, where individuals who do not wish to donate become donors.
The US currently employs an opt-in system. Last year, over 28,000 transplants were made possible due to organ donors. Unfortunately, about 18 people die every day due to a shortage of donated organs.
The Great Debate: In or Out?
The researchers from the University of Nottingham, University of Stirling, and Northumbria University analyzed the organ donation systems of 48 countries over a 13-year period, including 23 opt-in and 25 opt-out systems.
They found that countries using opt-out systems had higher total numbers of kidneys donated, an organ that the majority of people on organ transplant lists are anxiously waiting for. Opt-out systems also boasted the greater overall number of organ transplants.
Opt-in systems, however, had a higher rate of kidney donations from living donors. This apparent influence of policy on living donation rates "has not been reported before," says Prof. Ferguson, "and is a subtlety that needs to be highlighted and considered."
The authors acknowledge that their study was limited by not distinguishing between different degrees of opt-out legislation, with some countries requiring permission from next-of-kin for organs to be donated. The observational nature of the study also meant that other factors influencing organ donation remained unassessed.
The Road Ahead
The researchers published their findings in BMC Medicine, stating that "opt-out consent may lead to an increase in deceased donations but a reduction in living donation rates. Opt-out consent is also associated with an increase in the total number of livers and kidneys transplanted."
They suggest that these results could be used in the future to inform policy decisions, although they could be strengthened further through the routine collection of international organ donation information, such as consent type, procurement procedures, and hospital bed availability, which should then be made publicly available.
Prof. Ferguson proposes that future studies should examine the opinions of those who must make the decision to opt in or opt out:
"Further research outside of this country-level epidemiological approach would be to examine issues from the perspective of the individual in terms of beliefs, wishes, and attitudes, using a mixture of survey and experimental methods."
"By combining these different research methods," he says, "researchers can develop a greater understanding of the influence of consent legislation on organ donation and transplantation rates."
The authors note that countries using opt-out consent still experience organ donor shortages. A complete system overhaul is, therefore, unlikely to solve such a problem. They suggest that consent legislation or adopting aspects of the "Spanish Model" could be potential solutions to improve donor rates.
Spain currently boasts the highest organ donation rate in the world. Their success is credited to measures such as a transplant coordination network that operates on both a local and national scale, and enhancing the quality of public information available about organ donation.
Recently, Medical News Today ran a spotlight feature on the debate of using animal organs for human transplants. Could this be a solution to the organ shortage, or should the focus be on changing organ donation policy?

Additional Insights
- Altruism: Many individuals donate organs due to altruistic reasons, feeling it is a moral obligation to help others [1].
- Family Obligation: Feeling obligated to help family members is also a common reason for living donation [1].
- Cultural and Religious Beliefs: These can significantly impact the willingness to donate, with some cultures or religions having objections to organ donation [2].
- Educational Awareness: Higher awareness and understanding of organ donation processes can encourage more people to consider living donation.
- Legal and Ethical Frameworks: Countries with supportive legal frameworks and clear ethical guidelines tend to facilitate higher living donation rates.

- The debate between opt-in and opt-out organ donation policies continues to challenge policymakers, with researchers in Nottingham, Stirling, and Northumbria Universities examining the impact of these systems on donation rates.
- Researchers found that countries using opt-out systems had higher numbers of kidneys donated and a greater overall number of organ transplants, but a lower rate of kidney donations from living donors.
- In contrast, opt-in systems had a higher rate of kidney donations from living donors, but facing a higher number of false negatives, where potential donors do not sign up.
- The researchers propose that their findings can aid in informing policy decisions, suggesting the routine collection of international organ donation information to strengthen their results.
- Future studies should focus on the perspectives of individuals making the decision to opt in or opt out, analyzing their beliefs, wishes, and attitudes.
- Countries like Spain, with a high organ donation rate, implement measures such as a transplant coordination network, enhancing the quality of public information available about organ donation, and addressing cultural and religious beliefs that hinder donation. A complete system overhaul may not solve the organ shortage issue, but adopting aspects of the "Spanish Model" could potentially improve donor rates.
