Debating Organ Donation: Which System - Opt-In or Opt-Out - Is More Effective?
Organ donation policies across the globe are a hot topic, with countries adopting either opt-in or opt-out systems. Let's dive into a study by researchers from the UK that analyzes the efficiency of both approaches.
In the opt-in system, individuals are required to actively opt-in, or sign up, to donate their organs after death. On the other hand, opt-out systems automatically assume consent for organ donation unless a specific request is made for organs not to be taken before death.
Prof. Eamonn Ferguson, the lead author from the University of Nottingham in the UK, acknowledges the drawbacks of these systems. In the opt-in system, people might not act for reasons such as loss aversion, effort, and believing the policy makers' decisions to be correct. This can lead to false negatives, where individuals who wish to donate do not donate. Conversely, in an opt-out system, inaction can potentially lead to false positives, where an individual that does not want to donate might become a donor.
The US currently operates under an opt-in system, with around 28,000 transplants having taken place last year thanks to organ donors. In spite of these efforts, around 18 people are still dying daily due to a shortage of donated organs.
Researchers from the University of Nottingham, University of Stirling, and Northumbria University in the UK scrutinized the organ donation systems in 48 countries over a 13-year period, finding that countries with opt-out systems had more total kidneys donated. Opt-out systems also reported the greater overall number of organ transplants. Interestingly, opt-in systems demonstrated a higher rate of kidney donations from living donors.
Though the authors acknowledge their study had limitations, such as not differentiating among varying degrees of opt-out legislation, they assert that opt-out consent may result in an increase in deceased donations but reduce living donation rates. Additionally, opt-out consent was associated with more livers and kidneys being transplanted overall.
The researchers recommend that their results could prove helpful in the future, shaping policy decisions. They propose further collection and public availability of international organ donation information, including consent type, procurement procedures, and hospital bed availability. Additionally, they suggest exploring individual beliefs, wishes, and attitudes towards donating through survey and experimental methods.
Though countries with opt-out systems still experience donor shortages, the authors suggest that changing the system entirely is unlikely to solve the problem. Instead, changes to consent legislation or adopting elements of the Spanish Model could potentially raise donation rates.
Spain boasts the highest organ donation rate globally, with measures like a well-organized transplant coordination network, effective communication, and trust in the forefront of their success. However, the question lingers—is farming animal organs for human transplants a potential solution to the organ shortage, or should the focus be on updating donation policies? Only time will tell.

Uncensored Enrichment Data:
- Spain, France, Portugal, Wales (UK), Netherlands (as of 2020), Austria, Belgium, Argentina, and Colombia are notable examples of countries using opt-out organ donation systems.
- In contrast, the United States, Germany, Denmark, Sweden (previously opt-out, now mixed),and Kazakhstan* operate under opt-in systems.
- Among the countries using opt-out systems, Spain achieves the highest global rate of deceased organ donors (33-35 donors per million population), thanks to its well-organized policy, effective transplant coordination, and high public trust.
- France comes second with 23.2 donors per million population, though it still trails behind Spain due to differences in efficiency and public trust.
- Kazakhstan, despite employing an opt-in system, has a very low deceased donor rate, with just 0.3 donors per million population in 2024. This shows the challenges that low public awareness and high refusal rates among relatives present.
- The UK study on organ donation policies reveals that countries with opt-out systems, such as Spain, France, and Portugal, tend to have more total kidneys donated and a greater number of overall organ transplants.
- On the other hand, the US, operating under an opt-in system, reported higher rates of kidney donations from living donors, despite experiencing daily deathsdue to a shortage of donated organs.
- The researchers suggest that adopting elements of the Spanish Model, which includes a well-organized transplant coordination network, effective communication, and high public trust, could potentially raise donation rates.
- Science continues to explore alternative solutions to the organ shortage, raising the question of whether farming animal organs for human transplants could be a viable solution, or if the focus should instead be on updating donation policies and increasing public awareness.
