Discussion on Organ Donation: Which System (Opt-In or Opt-Out) Favors More Donations?
Torching Through the Organ Donation World
Organ donation policies? To opt in or opt out? Let's dive into the organ donation policies of 48 countries to figure out the frickin' best approach.
With an opt-in system, individuals have to actively provide their consent to join a registry for organ donation postmortem. In contrast, opt-out systems automatically donate organs unless someone explicitly asks not to.
Prof. Eamonn Ferguson, hailing from the University of Nottingham, UK, recognizes the pitfalls of both systems:
"People might not act for various reasons, such as loss aversion, inaction, or trusting decision-makers to have made the right call."
Inaction in an opt-in system can seemingly lead to individuals who would wish to donate not actually donating (a false negative). Conversely, inaction in an opt-out system might result in someone unwilling to donate becoming a donor (a false positive).
The United States adopts an opt-in approach. Last year, approximately 28,000 transplants were facilitated due to organ donors. Around 79 people receive organ transplants daily, yet around 18 indirectly succumb to the lack of donated organs daily.
In or out? A Study
Researchers from the University of Nottingham, the University of Stirling, and Northumbria University in the UK scrutinized the organ donation protocols of 48 countries over 13 years, with 23 implementing opt-in and 25 opt-out systems.
The study's authors measured overall donor numbers, transplants per organ, and the total number of kidneys and livers donated, both from deceased and living donors.
They found that countries with opt-out systems had significantly more kidneys donated—the organ sought by the majority of those on the organ transplant waiting list. Opt-out systems also boasted the greater overall number of organ transplants.
Opt-in systems, however, displayed a higher rate of kidney donations from living donors. This apparent influence of policy on living donation rates "has not been reported before," says Prof. Ferguson, "and is a subtler point that demands attention."
The authors acknowledge that their study was limited by its inability to differentiate between varying degrees of opt-out legislation, as some countries required permission from next-of-kin for organs to be donated. Additionally, the observational nature of the study left unassessed other factors contributing to organ donation.
Moving Forward
The researchers state that their findings, published in BMC Medicine, suggest that "opt-out consent may lead to an increase in deceased donation but a reduction in living donation rates. Opt-out consent is also associated with an increase in the total number of livers and kidneys transplanted."
They propose that these results could aid future policy decisions, but stress that they could be strengthened further through the regular collection and distribution of international organ donation information, such as consent type, procurement procedures, and hospital bed availability.
Prof. Ferguson suggests that future studies should also explore individual perspectives and beliefs regarding organ donation. This research might provide insights into why some opt in or out.
"Further research outside of this country-level epidemiological approach would be to examine the beliefs, wishes, and attitudes of individuals, using a combination of surveys and experiments," he says.
Countries utilizing opt-out consent still experience organ donor shortages. A complete overhaul of the system may not erase the issue. Instead, consent legislation or elements of the "Spanish Model" could help boost donor rates.
Spain currently boasts the highest organ donation rate worldwide. Their success is attributed to a transplant coordination network that functions both locally and nationally, as well as enhanced public information regarding organ donation.
Recent debate has sparked over whether farm-raised animal organs could be a solution to the organ shortage. This idea raises questions about whether the organ shortage can be addressed through changes to organ donation policy instead.
- In contrast to opt-in systems, countries with opt-out organ donation policies tend to have a higher number of kidneys donated, which is the organ most sought after by those on organ transplant waiting lists.
- The study conducted by researchers from the University of Nottingham, University of Stirling, and Northumbria University highlighted that countries with opt-out systems also boast a greater overall number of organ transplants.
- However, opt-in systems displayed a higher rate of kidney donations from living donors, a fact that Prof. Ferguson found noteworthy as it has not been reported before.
- Although the study found that opt-out consent may lead to increased deceased donation and total number of livers and kidneys transplanted, it also suggested a reduction in living donation rates.
- Prof. Ferguson proposes that future studies should delve into individual perspectives and beliefs regarding organ donation, as this research could provide insights into why some opt in or out.
- The debate over whether farm-raised animal organs could potentially solve the organ shortage brings into question whether the issue can be addressed through changes to organ donation policy rather than relying on animal sources.
