Controversy over Organ Donation: Pros and Cons of Opt-In vs. Opt-Out Approach
Going globe-trotter on organ donation policies! Is it better to opt-in or opt-out? That's the million-dollar question, and a team of researchers from the UK is on a mission to find the answer.
By analyzing the organ donation protocols of 48 Countries, they've been keeping score of the two systems:
- Opt-in: The voluntary method where people actively sign-up to donate their organs post-mortem.
- Opt-out: The automatic process where donation occurs unless a specific request is made against it.
Prof. Eamonn Ferguson, the lead author from the University of Nottingham, UK, sheds some light on potential drawbacks of both systems:
"People may not act for numerous reasons, including loss aversion, effort, and believing that the policy makers have made the 'right' decision and one that they believe in."
Now, let's grapple with a beasty concept: false positives and negatives.
Inaction in an opt-in system could lead to folks who'd want to be donors not donating (a false negative). On the flip side, inaction in an opt-out system could potentially turn an individual who doesn't want to donate into a donor (a false positive).
For example, dealings in the US with the opt-in system yielded around 28,000 transplants last year, but 18 people died each day, unable to receive surgery due to the scarcity of donated organs.
To In or Out?
The research gang from the University of Nottingham, University of Stirling, and Northumbria University took a deep dive into the organ donation systems of 48 Countries over a period of 13 years: 23 opted for the opt-in method, whereas 25 were on the opt-out bandwagon.
They measured overall donor numbers, transplant numbers per organ, and the total number of kidneys and livers transplanted from both deceased and living donors.
Guess what? Countries using opt-out systems had a higher number of kidneys donated, the most sought-after organ by folks on transplant lists. Opt-out systems also recorded a higher overall number of organ transplants.
However, opt-in systems showed a higher rate of kidney donations from living donors. The team points out that they've spotted something new and not so mainstream – the apparent influence that policy had on living donation rates.
The researchers acknowledge that their study has its limitations, including not making distinctions between varying degrees of opt-out laws. Also, other factors contributing to organ donation remain unassessed due to the observational nature of the study.
So, what do we make of the results published in BMC Medicine?
Well, the researchers indicate that opt-out consent may result in an increase in deceased donations but a decrease in living donation rates. Opt-out consent is also associated with an increase in the total number of livers and kidneys transplanted.
This data can potentially inform decisions on organ donation policies, but the team suggests refining the results through the regular collection of international organ donation info, such as consent type, procurement procedures, and hospital bed availability. They believe making this info publicly available can help further strengthen the findings.
Prof. Ferguson thinks future research should explore the views of those called upon to opt in or opt out, focusing on their beliefs, wishes, and attitudes. He suggest that by combining several research methods, researchers can develop a greater understanding of the impact of consent legislation on organ donation and transplantation rates.
A significant finding of the study was that countries using opt-out consent still grapple with donor shortages. The authors opine that changing the system of consent might not solve this issue. Instead, they propose considering consent legislation or adopting aspects of the "Spanish Model" could help boost donor rates.
The Spanish have the highest organ donation rate globally, thanks to an opt-out consent approach. Experts credit the Spanish success to features like their transplant coordination network that operates locally and nationally, and the quality of public information available about organ donation.
Intrigued by the antler trade? Read about the potential of using animal organs for human transplants—could it be the panacea for organ shortages, or should attention focus on tweaking organ donation policies?

- The research team from the University of Nottingham, University of Stirling, and Northumbria University, after analyzing organ donation protocols in 48 countries for 13 years, found that opt-out systems resulted in higher numbers of kidney donations, the most sought-after organ, and overall organ transplants.
- In contrast, opt-in systems showed a higher rate of kidney donations from living donors, and the team noticed an apparent influence of policy on living donation rates.
- However, the study's limitations include not making distinctions between varying degrees of opt-out laws and not assessing other contributing factors due to the observational nature of the study.
- The authors suggest refining the results through regular collection of international organ donation information, such as consent type, procurement procedures, and hospital bed availability, and making this information publicly available.
- The researchers indicate that opt-out consent may increase deceased donations but decrease living donation rates, and suggest future research should explore the views of those called upon to opt in or opt out to gain a greater understanding of the impact of consent legislation on organ donation and transplantation rates.
- Despite the high organ donation rate in Spain due to an opt-out consent approach, the authors note that changing the system of consent might not solve donor shortages and propose considering aspects of the "Spanish Model," like their transplant coordination network and quality of public information about organ donation, as potential solutions.
