Debate over Organ Donation: Which Consensus - Opt-In or Opt-Out - Yields More Donations?
Worldwide, the methodology for organ donation varies significantly, prompting the question: Is it more effective to have an opt-in or opt-out system in place? To answer this, researchers from the UK have scrutinized the organ donation protocols of 48 nations.
In opt-in systems, individuals are required to actively register their intention to donate organs post mortem. On the other hand, opt-out systems mean that organ donation will automatically occur unless a request has been made to not donate.
"A reliance on active participation from individuals can lead to shortcomings," notes Prof. Eamonn Ferguson, lead author from the University of Nottingham, UK. "People may not act for various reasons, including loss aversion, effort, and trusting that the authorities have made the right decision."
An inaction in an opt-in system could result in individuals who would have wanted to donate not doing so (false negative). Conversely, inaction in an opt-out system could potentially lead to an individual who did not wish to donate becoming a donor (false positive).
The US, using an opt-in system, saw 28,000 transplants last year due to organ donors. Despite this, around 18 people die daily due to a lack of available organs.
The research team from the University of Nottingham, University of Stirling, and Northumbria University compared the organ donation systems of 48 countries over a 13-year period. They found that countries with opt-out systems donated more kidneys, the organ most commonly needed by those on organ transplant waiting lists. Opt-out systems also reported higher overall organ transplant numbers.
Interestingly, opt-in systems demonstrated a higher rate of kidney donations from living donors. However, the authors of the study caution that their findings were limited as they did not differentiate between various degrees of opt-out legislation and did not evaluate other factors that could influence organ donation.
The authors suggest their findings could guide future policy decisions. They propose that the collection and public availability of international organ donation data, including consent type, procurement procedures, and hospital bed availability, would strengthen their research.
Looking ahead, Prof. Ferguson suggests further research focusing on the perspectives of those making the decision to opt in or opt out. "By combining survey and experimental methods, researchers can develop a deeper understanding of the impact of consent legislation on organ donation and transplantation rates," says Prof. Ferguson.
The authors note that countries with opt-out consent still face organ donor shortages. They suggest that modifying the system of consent or adopting elements of the "Spanish Model" could potentially improve donor rates.
Spain, with the highest organ donation rate globally, uses opt-out consent, but experts attribute their success to additional measures such as a transplant coordination network and improved public information about organ donation.
Questions surrounding alternative solutions to the organ shortage, such as farming animal organs for human transplants, have recently been raised. Whether this could be a viable solution or one to be addressed through changes to organ donation policy remains to be seen.
