Debate over organ donation: should it be a choice or an assumed decision?
To Opt-In or Not? The Great Organ Donation Debate
Organ donation policies are as diverse as the countries that enforce them. A fascinating study by a group of researchers from the UK investigated the effectiveness of opt-in and opt-out systems in 48 countries across 13 years. So, which system really works best?
An opt-in system means people must actively register to become organ donors post-mortem. opt-out systems, on the other hand, automatically authorize organ donation unless a specific request is made to withhold it before death.
Prof. Eamonn Ferguson, the study's lead author from the University of Nottingham, explains that while both systems require active participation, procrastination, loss aversion, and effort can lead individuals to take no action.
However,failure to act under an opt-in system might result in potential donors who wish to donate failing to do so (a false negative). On the flip side, inaction in an opt-out system may lead to individuals who do not wish to donate becoming donors (a false positive).
The US previously utilized an opt-in system, with approximately 28,000 transplants facilitated in the previous year, as reported by the US Department of Health & Human Services. Sadly, around 18 people die each day due to a lack of donated organs.
Researchers from the University of Nottingham, University of Stirling, and Northumbria University analyzed the organ donation systems in place across 48 countries. They uncovered that countries employing an opt-out system had a higher number of total kidneys donated, the organ most desperately needed by those on the organ transplant waiting list. Additionally, these countries also had a greater overall number of organ transplants.
On the contrary, opt-in systems showed a higher rate of kidney donations from living donors. This impact of policy on living donation rates has not previously been reported, according to Prof. Ferguson.
The authors of the study, though, pointed out several limitations. The research lacked distinction between varying degrees of opt-out legislation and could not account for other influences on organ donation.
Prof. Ferguson suggests that future research should examine individual beliefs, wishes, and attitudes towards donation, using both surveys and experimental methods. This could provide a more comprehensive understanding of the impact of consent legislation on donation and transplantation rates.
While opt-out systems generally lead to higher donation rates due to lower barriers to registration, they may result in a misalignment with preferences if individuals do not opt out because of lack of awareness or effort. Completely changing the system is unlikely to solve organ donor shortages, as even opt-out countries still experience shortages. Instead, consent legislation or adopting aspects of the "Spanish Model" could potentially improve donor rates.
The Spanish Model, used in Spain, boasts the highest organ donation rate in the world. Their success is attributed to measures such as a transplant coordination network operating locally and nationally, and improved public information about organ donation.
Recently, Medical News Today ran a feature discussing potential solutions to the organ shortage, such as farming animal organs for human transplants. Could this offer a solution, or should we focus on modifying organ donation policies instead?

Insights on Opt-In vs. Opt-Out Organ Donation Systems:
Advantages and Disadvantages of Opt-in System:
- Explicit Consent: Ensures individuals make an informed decision to become donors.
- Transparency: Communicates the need for action to become a donor.
- Low Registration Rates: Often results in low registration rates due to procrastination and the effort required to sign up.
- Potential for Missed Donations: People may support donation but fail to register due to various barriers.
Advantages and Disadvantages of Opt-out System:
- Higher Donation Rates: Reduces barriers to registration and leads to higher rates compared to opt-in systems.
- Reduced Barriers: Simplifies the process of becoming a donor by assuming inaction as consent.
- Potential Misalignment with Preferences: May result in some individuals not knowing they are donors or may not opt out due to lack of awareness or effort.
- Ethical Concerns: Raises questions about presumed consent without explicit agreement from all individuals.
- The study conducted by researchers from the University of Nottingham and other institutions revealed that opt-out systems have a higher number of total kidneys donated and a greater overall number of organ transplants compared to opt-in systems.
