Organ Donation: Which System - Opt-In or Opt-Out - Is More Effective?
Pondering Organ Donation Policies: Opt-In vs. Opt-Out
Organ donation policies across the globe display a vast array of variations. But which approach, opt-in or opt-out, yields the best results? To delve into this question, a team of researchers from the UK analyzed the organ donation regulations of 48 countries to determine the most effective strategy.
When it comes to opt-in systems, individuals need to sign up to a registry to donate their organs post-mortem. In contrast, opt-out systems mandate organ donation if no explicit request to the contrary is made before death for unclaimed organs.
Prof. Eamonn Ferguson, the lead author from the University of Nottingham, UK, acknowledged the potential pitfalls of both systems:
"People may not act due to numerous reasons such as loss aversion, effort, and believing that policy makers have already made the 'right' decision."
Inaction in an opt-in system might result in potential donors not donating (a false negative). On the other hand, a lack of action in an opt-out system could lead to an individual who does not wish to donate becoming a donor (a false positive).
The United States adheres to an opt-in system, with over 28,000 transplants performed last year, thanks to organ donors. Regrettably, around 18 people still die daily due to a scarcity of donated organs despite receiving life-saving transplants.
In or out?
The researchers from the University of Nottingham, University of Stirling, and Northumbria University in the UK scrutinized the organ donation policies of 48 countries over a span of 13 years, with 23 using an opt-in system and 25 implementing an opt-out system.
The study authors compared overall donor numbers, organ transplant numbers, and the total number of kidneys and livers transplanted from both deceased and living donors.
Their findings revealed that countries employing opt-out systems had higher total kidney donation numbers, the organ that most people on organ transplant lists are yearning for. Additionally, these opt-out systems saw a greater overall number of organ transplants.
Opt-in systems, however, boasted a higher rate of kidney donations from living donors. The influence of policy on living donation rates, as Prof. Ferguson points out, is a subtlety that has yet to be highlighted.
The authors concede that their study may have fallen short by not differentiating between degrees of opt-out legislation, with some countries requiring permission from next-of-kin for organs to be donated. Additionally, the observational nature of the study left unassessed factors that may influence organ donation.
Moving forward
The researchers published their findings in BMC Medicine. They concluded that opt-out consent might lead to an increase in deceased donations but a decrease in living donations. Opt-out consent is also associated with an increase in transplanted livers and kidneys.
They advocate that these results may be utilized in policy-making decisions in the future, provided international organ donation data is routinely collected and made publicly available. They also suggest exploring the opinions of individuals who make the decision to opt in or opt out via survey and experimental methods.
The authors note that countries using opt-out consent still struggle with organ donor shortages. completely revising the system of consent is, therefore, unlikely to solve the problem. Instead, they suggest exploring alternate solutions, such as altering consent legislation or adopting aspects of the "Spanish Model," which emphasizes a transplant coordination network and improved public information about organ donation.
A recent article from Medical News Today scrutinized the feasibility of farming animal organs for human transplants in addressing the organ shortage. This topic deserves further examination to establish whether it represents a viable solution or if it should be tackled through changes to organ donation policy.

- In the context of medical-health conditions, science should examine the feasibility of farming animal organs for human transplants as a potential solution to the ongoing organ shortage.
- The study by researchers from the UK revealed that opt-out consent might lead to an increase in deceased donations and transplanted livers and kidneys, but a potential decrease in living donations.
- The science of transplantation could benefit from retargeting efforts to understand the influence of policy on living donation rates and to explore the opinions of individuals about opt-in or opt-out consent policies.
- The results of the study on organ donation policies suggest that completely revising the system of consent may not solely solve the problem of organ shortages; instead, alternate solutions like altering consent legislation or adopting aspects of the "Spanish Model" should be explored.
