Organ Donation: Which Approach - Opt-In or Opt-Out - Yields More Success?
Organ Donation: Opt-In or Opt-Out?
Globally, the approach to organ donation varies significantly. To examine the best system, a team of researchers from the UK analyzed the organ donation protocols of 48 countries.
Under an opt-in system, individuals need to actively register to donate their organs post-mortem. In contrast, an opt-out system presumes organ donation unless an individual explicitly requests otherwise before death.
Prof. Eamonn Ferguson, the lead author from the University of Nottingham, acknowledges potential drawbacks of both systems:
"People's inaction can stem from diverse reasons such as loss aversion, lack of effort, and trust in policy-makers' decisions."
It's worth noting that in an opt-in system, inaction might lead to individuals who would've liked to donate not doing so (a false negative). Conversely, in an opt-out system, inaction could result in individuals who don't wish to donate becoming donors (a false positive).
The US currently operates an opt-in system. According to the US Department of Health & Human Services, about 28,000 transplants were made possible last year due to organ donors. Regrettably, approximately 18 individuals die each day due to a shortage of donated organs.
In or out?
Researchers from the University of Nottingham, the University of Stirling, and Northumbria University analyzed the organ donation systems of 48 countries for 13 years, finding that:
- Countries employing an opt-out system had higher total numbers of kidneys donated (the organ in highest demand for transplant lists).
- Opt-out systems also recorded the greatest overall number of organ transplants.
Opt-in systems, however, displayed a higher rate of kidney donations from living donors. The researchers found that this influence on living donation rates was previously unreported.
The study authors acknowledge that their research was limited by not considering varying degrees of opt-out legislation and other factors that might influence organ donation.
Moving forward
The researchers suggest their findings could be utilized in the future to help shape organ donation policies. To strengthen their results, they recommend the collection of international organ donation data, such as consent type, procurement procedures, and hospital bed availability, which should then be made public.
Future studies could also delve into the attitudes and beliefs of individuals facing the decision to opt-in or opt-out.
The authors note that even countries with opt-out consent experience organ donor shortages. Completely changing the system may not solve these issues. Instead, altering consent legislation or incorporating aspects of the Spanish Model, known for its high donation rates, could help improve donor rates.
Spain's success is attributed to factors such as a transplant co-ordination network and improved public information on organ donation.
Recently, Medical News Today covered controversies surrounding the farming of animal organs for human transplants. Might this be a potential solution for the organ shortage issue, or should it be tackled through improvements to organ donation policies?

### Insights: - Opt-out systems are generally associated with higher organ donation rates compared to opt-in systems. - The Spanish Model involves opt-out consent, but its success is attributed to additional factors such as a transplant co-ordination network and improved public information on organ donation. - Policymakers could consider altering consent legislation or adopting aspects of the Spanish Model to potentially increase organ donor rates. - Farming animal organs for human transplants is a topic of debate, with implications for the ethics and potential impact on animal welfare.
- The researchers from Nottingham, Stirling, and Northumbria Universities found that countries with opt-out organ donation systems have higher overall numbers of organ transplants, including kidneys, which are in the highest demand.
- Opt-out systems also recorded a greater number of kidney donations from deceased donors compared to opt-in systems, a finding previously unreported in the literature.
- However, opt-in systems showed a higher rate of kidney donations from living donors, indicating that both systems have unique advantages.
- As the research is limited, it recommends the collection of international organ donation data, such as consent type, procurement procedures, and hospital bed availability, to strengthen existing findings.
- Future studies could explore the opinions and beliefs of individuals deciding whether to opt-in or opt-out of organ donation, seeking a better understanding of public attitudes.
- Policymakers are advised to consider altering consent legislation or adopting aspects of the successful Spanish Model to potentially increase organ donor rates, rather than completely changing the system, as additional factors such as a transplant coordination network and improved public information on organ donation are crucial to success.
