Organ donation policies: Discussing the merits of consent-based or presumed consent approaches
Donating Organs: Opt-In or Opt-Out? A Global Comparison
Organ donation regulations differ worldwide, sparking the question - is it better to have a system where people must actively opt-in or one that defaults to opt-out? To explore this, a team of researchers from the UK examined the organ donation procedures of 48 countries.
In an opt-in system, individuals must proactively register to donate their organs post-mortem. In contrast, opt-out systems presume organ donation unless a specific request is made before death to avoid donation.
Prof. Eamonn Ferguson, the lead author from the University of Nottingham, acknowledges potential drawbacks of this active decision requirement:
"People may not act due to numerous reasons, such as loss aversion, effort, and trusting the government's decision."
Laziness in an opt-in system can lead to folks who'd wish to donate not doing so (false negatives). Conversely, idleness in an opt-out system could result in someone who doesn't want to donate becoming one (false positive).
The US employs an opt-in system. Last year, 28,000 transplants were carried out due to organ donors, with approximately 79 folks receiving transplants daily. Unfortunately, around 18 individuals die daily due to a scarcity of donated organs.
Researchers from the University of Nottingham, University of Stirling, and Northumbria University reviewed the donation systems of 48 countries over a period of 13 years. Their analysis compared 23 countries using an opt-in system with 25 using an opt-out system.
They discovered that countries adhering to an opt-out system donated more kidneys overall - the organ most frequently sought by those on transplant lists. Opt-out systems also had a greater total number of organ transplants.
Opt-in systems, however, boasted a higher rate of kidney donations from living donors. Prof. Ferguson notes, "This influence of policy on living donation rates has not been reported before, and it’s a subtlety that needs attention."
The authors acknowledge their study's limitations, like not differentiating between varying opt-out legislation or assessing other factors influencing organ donation.
With their findings, featured in BMC Medicine, the researchers note that opt-out consent tends to lead to a rise in deceased organ donation but a drop in living donation rates. Moreover, opt-out consent contributes to an increase in the total number of livers and kidneys transplanted.
While their findings could help guide future policy decisions, the authors suggest that they could be bolstered further through the systematic collection and public disclosure of international organ donation information, like consent type, procurement procedures, and hospital beds availability.
Prof. Ferguson believes future studies should explore the perspectives of those who must decide to opt-in or opt-out:
"Additional research could investigate issues from the standpoint of the individual and their beliefs, wishes, and attitudes, using a mix of surveys and experiments."
The team suggests that while opt-out consent may enhance deceased donation rates, it is unlikely to resolve the donor shortage issue. Instead, the researchers propose modifying organ donation policies or adopting elements of the 'Spanish Model' to augment donor rates.
Spain boasts the highest global organ donation rate. The Spanish employ opt-out consent, but experts attribute their success to measures such as a transplant coordination network operating nationally and locally, as well as improved public information about organ donation.
Recently, Medical News Today featured an article discussing whether farming animal organs for human transplants could bridge the organ shortage gap. Is this a viable solution or a problem that could be resolved through revised organ donation policies?

- Laziness in an opt-in system can lead to some individuals who wish to donate not doing so, resulting in false negatives.
- On the other hand, idleness in an opt-out system could lead to someone who doesn't want to donate becoming a donor, which is considered a false positive.
- The study, published in BMC Medicine, found that countries adhering to an opt-out system donate more kidneys overall, and they also have a greater total number of organ transplants.
- However, opt-in systems have a higher rate of kidney donations from living donors, and this influence of policy on living donation rates has not been reported before.
