Organ Donation: Which System - Opt-In or Opt-Out - Is More Effective?
Organ donation policies differ worldwide, and there's a hot debate about whether an opt-in or an opt-out system works best. To settle the score, researchers from the UK dived deep into the organ donation protocols of 48 countries for a whopping 13 years, scrutinizing both opt-in (23 countries) and opt-out (25 countries) systems.
In an opt-in system, people have to actively register themselves as organ donors post mortem. Opt-out systems, on the other hand, assume consent for organ donation unless someone specifically mentions their refusal before death. Prof. Eamonn Ferguson, the study's ringleader from the University of Nottingham, acknowledges that the reliance on individual decisions can have its downsides:
"People might not act for various reasons, such as loss aversion, lack of effort, and the belief that policy-makers have made the right decision that they can trust."
Now, here's the crux — inaction in an opt-in system may lead to those who'd want to donate not doing so (a false negative). In contrast, inaction in an opt-out system could potentially lead to someone who doesn't want to donate becoming one (a false positive).
The US leans towards an opt-in system. Last year, over 28,000 transplants were made possible, with around 79 transplants happening daily. Despite this, approximately 18 people still die daily due to a scarcity of donated organs.
The researchers unearthed some eye-opening findings. Countries with opt-out organ donation systems had a higher total number of kidneys donated — an organ that most people waiting for organ transplants are yearning for. Moreover, opt-out systems beat out opt-in systems in the overall number of organ transplants.
Opt-in systems, however, boasted a higher rate of kidney donations from living donors. The impact of policy on living donation rates? A revelation not reported before, says Prof. Ferguson.
The study has its limitations. It didn't distinguish between varying degrees of opt-out legislation in different countries or assess other factors affecting organ donation.
Moving forward, the researchers suggest that their findings could guide future policy decisions on organ donation. They also advocate for collecting international organ donation information, such as consent type, procurement procedures, and hospital bed availability, to reinforce their study and make the data publicly accessible.
Prof. Ferguson proposes that future studies should delve deeper into the opinions and attitudes of individuals making the life-and-death decision:
"By combining survey and experimental methods, researchers can gain a better understanding of how consent legislation influences organ donation and transplantation rates."
The authors emphasize that countries with opt-out consent still face donor shortages. Revolutionizing the system might not solve such a problem. Instead, they recommend revisiting consent legislation or implementing aspects of the "Spanish Model" to boost donor rates.
Spain is the proud owner of the world's highest organ donation rate. Spain employs an opt-out system, but experts attribute its success to a robust transplant coordination network, working both locally and nationally, and the improved quality of public information available on organ donation.
The debate on whether to farm animal organs for human transplants has been a hot topic recently. Could this perhaps be a solution to the organ shortage, or should it be addressed through changes to organ donation policy?

- The reliance on individual decisions in an opt-in system can lead to those who'd want to donate not doing so, resulting in false negatives.
- On the other hand, inaction in an opt-out system could potentially lead to someone who doesn't want to donate becoming one, which is considered a false positive.
- In their study, researchers found that countries with opt-out organ donation systems had a higher total number of kidneys donated, beating out opt-in systems in the overall number of organ transplants.
- Despite these findings, opt-in systems boasted a higher rate of kidney donations from living donors, a phenomenon that was previously not reported in science.
