Debating Organ Donation: Which System – Opt-In or Opt-Out – Is More Effective?
Laid-Back Take on Organ Donation: Opt-In or Opt-Out?
Organ donation policies around the globe sure are a hot topic! A team of UK researchers has dug deep into the donation protocols of 48 nations to figure out which approach is working best: opt-in or opt-out.
In an opt-in system, you've gotta actively sign up to donate your organs post-mortem. But in the opt-out system, your organs will be donated automatically unless you specifically request otherwise before you kick the bucket.
Prof. Eamonn Ferguson, our main man from the University of Nottingham, acknowledges that drawbacks can arise when relying solely on an active individual decision. "People may dilly-dally for numerous reasons, including loss aversion, effort, and thinking policy makers have already made the 'right' choice," he says.
Here's the kicker: while inaction in an opt-in system can result in individuals who'd want to donate not donating (a false negative), the same inaction in an opt-out system could potentially result in an individual who doesn't want to donate becoming one (a false positive).
In the United States, home of the opt-in system, around 28,000 transplants took place last year due to organ donors, with approximately 79 people receiving organ transplants every day. Unfortunately, around 18 people die every day without surgery due to a shortage of donated organs.
The researchers from the University of Nottingham, University of Stirling, and Northumbria University analyzed the organ donation systems of 48 nations over a 13-year period. They found that countries using the opt-out system generally had higher total numbers of kidneys donated - the organ most needed by those on organ transplant lists. Opt-out systems also recorded a greater overall number of organ transplants.
However, opt-in systems had a higher rate of kidney donations from living donors. This influence on living donation rates hasn't been noted before, says Prof. Ferguson, and it's something worth highlighting.
The researchers acknowledge their study had some limitations, such as not distinguishing between different degrees of opt-out legislation and not assessing factors influencing organ donation. Nonetheless, their findings, published in BMC Medicine, demonstrate that "opt-out consent may lead to an increase in deceased donation but a reduction in living donation rates." In addition, they showed an increase in the total number of livers and kidneys transplanted.
The researchers recommend that future decisions on policy could be informed by their results, and the routine collection and public availability of international organ donation information. They also suggest that future studies could delve into the beliefs, wishes, and attitudes of those making the decision to opt in or opt out, using a mix of surveys and experimental methods.
They additionally state that countries adopting opt-out consent still face organ donor shortages, so completely changing the system of consent is unlikely to solve the problem. Instead, they suggest that consent legislation or adopting aspects of the "Spanish Model" could help boost donor rates.
Spain currently has the highest organ donation rate in the world and is known for its opt-out consent, but their success is attributed to more than just the policy itself. For example, their use of a transplant coordination network working on both the local and national levels, improvement of public information about organ donation, and the provision of resources to facilitate donation, such as designating medical staff to facilitate quality organ retrieval, pave the way for their success.
Thinking outside of the box, some have considered whether farming animal organs for human transplants could be a solution to the organ shortage. That's a topic we might circle back to later on!

Insights:- Countries with opt-out organ donation systems tend to have higher organ donation rates compared to those with opt-in systems, but the higher rates are not solely due to the policy itself[1][3].- The key mechanism behind higher donation rates in opt-out systems is making donation the default, which reduces barriers and procrastination[3].- The effectiveness of opt-out systems depends on additional healthcare strategies and societal factors, rather than the policy alone[1][3][5].
- The study on organ donation policies across 48 nations found that countries using the opt-out system, where donation occurs automatically unless requested otherwise, generally had higher totals of kidneys donated and overall organ transplants.
- However, the researchers from the University of Nottingham, University of Stirling, and Northumbria University revealed that opt-in systems, in which individuals must actively consent to donate post-mortem, had a higher rate of kidney donations from living donors.
- The researchers suggest that future decisions on organ donation policies could be informed by their findings, emphasizing the importance of international organ donation information and the routine collection of such data.
- To combat organ donor shortages, the researchers recommend considering consent legislation, adopting aspects of the "Spanish Model," or exploring alternative solutions such as the farming of animal organs for human transplants.
- The increase in organ donation rates in opt-out systems is attributed to making donation the default, which reduces barriers and procrastination, but the effectiveness of these systems depends on additional healthcare strategies and societal factors.
- The idea of farming animal organs for human transplants has been considered as a potential solution to the organ shortage, a topic that may be further discussed in the future.
