Debate over Mandatory vs. Consent-Based Organ Donation Systems: Which Approach Is More Efficient?
Let's Talk Organ Donation: Opt-In vs. Opt-Out Systems
Organ donation policies across the globe exhibit a wide range of approaches. But which strategy - opt-in or opt-out - is more effective? A team of researchers from the UK set out to discover the answer, analyzing the organ donation protocols of 48 countries over a 13-year period.
In an opt-in system, individuals must register to a donor registry to donate their organs postmortem. In contrast, opt-out systems assume consent for organ donation unless explicitly requested not to take organs after death.
Prof. Eamonn Ferguson, the study's lead author from the University of Nottingham, UK, acknowledges that the reliance on active input from citizens may result in drawbacks:
"People may not act for numerous reasons, including loss aversion, effort, and believing that policy makers have made the 'right' decision."
While inaction in an opt-in system can result in individuals who would have wanted to donate not doing so (a false negative), inaction in an opt-out system may lead to an individual who does not wish to donate becoming a donor (a false positive).
The United States employs an opt-in system. Last year, 28,000 transplants were made possible thanks to organ donors, with approximately 79 transplants occurring daily. Regrettably, around 18 people die every day due to a deficiency in donated organs.
The Researchers' Finding
The researchers, hailing from the University of Nottingham, the University of Stirling, and Northumbria University in the UK, assessed the organ donation systems of 48 countries. They discovered that countries with opt-out systems had higher total numbers of kidneys donated, the organ most sought after by those on the organ transplant waitlist. Additionally, opt-out systems boasted the greater overall number of organ transplants.
Opt-in systems, however, excelled in kidney donations from living donors. This marked influence of policy on living donation rates, as stated by Prof. Ferguson, is a previously undiscussed factor.
Limitations and Future Research
The study had certain limitations, such as not distinguishing among varying degrees of opt-out legislation and not assessing other factors that might influence organ donation. The authors suggest that future studies could investigate individual opinions and attitudes towards organ donation to gain a deeper understanding of the impact of consent legislation on donation and transplantation rates.
Improving Organ Donation Rates
The study results indicate that opt-out consent may lead to an increase in deceased donations but a reduction in living donation rates. Additionally, opt-out consent is associated with an increase in the total number of livers and kidneys transplanted.
According to the authors, these results can guide future policy decisions, but they could be reinforced further through the routine collection and public accessibility of international organ donation information, such as consent type, procurement procedures, and hospital bed availability.
Countries employing opt-out consent still face organ donor shortages. A complete system change may not address such an issue. Instead, the authors suggest that consent legislation or adopting elements of the "Spanish Model" could potentially improve donor rates.
Could Animal Organs Be the Solution?
Spain currently boasts the highest organ donation rate globally. The Spanish utilize opt-out consent, but their success is attributed to measures such as a transplant coordination network that operates both locally and nationally, as well as improved public information about organ donation.
There's been recent debate over whether animal organs should be farmed for human transplants. Could this be a viable solution to the organ shortage, or should the focus instead be on changing organ donation policy?

Fun Fact: Did you know that kidneys are the most commonly transplanted organ? Over 95% of organ transplants worldwide involve kidneys.
- The researchers found that countries with opt-out organ donation systems had higher numbers of kidneys donated and a greater overall number of organ transplants.
- Opt-in systems excel in kidney donations from living donors, highlighting the influence of policy on living donation rates.
- The study suggests that opt-out consent may lead to an increase in deceased donations but a reduction in living donation rates, and is associated with an increase in the total number of livers and kidneys transplanted.
- In order to improve donor rates, the authors suggest that consent legislation or adopting elements of the "Spanish Model" could be beneficial, acknowledging that complete system change may not address organ donor shortages.
