Organ Donation: Which System - Opt-In or Opt-Out - Is More Effective?
Across the globe, the approach to organ donation differs significantly, prompting a study by researchers from the UK investigating whether an opt-in or opt-out system yields better results. In opt-in systems, individuals must actively register to donate their organs post mortem, while in opt-out systems, donation occurs automatically unless an individual specifically opts out.
Professor Eamonn Ferguson, the lead author from the University of Nottingham, acknowledges that reliance on individual decisions can lead to drawbacks such as inaction due to loss aversion, effort, or the belief that policy makers have made informed decisions. The US, utilizing an opt-in system, managed 28,000 organ transplants last year, but regrettably, 18 people still lost their lives due to a lack of available donated organs.
Researchers from the University of Nottingham, the University of Stirling, and Northumbria University compared the organ donation protocols of 48 countries for a 13-year period, finding that countries implementing opt-out systems had higher kidney donation numbers – the organ most sought after by those on the transplant list. Opt-out systems also showed a greater overall number of organ transplants. However, opt-in systems had a higher rate of kidney donations from living donors.
According to the study, published in BMC Medicine, opt-out consent might lead to an increase in deceased organ donations, yet reduce living donation rates. It was also noted that opt-out consent resulted in higher numbers of livers and kidneys transplanted overall. The researchers suggest that while the findings offer potential insight into future policy decisions, more comprehensive international organ donation data should be regularly collected and made public to further strengthen the study.
Professor Ferguson suggests that future research could delve into individual perspectives on the opt-in or opt-out choices, focusing on beliefs, desires, and attitudes to gain a deeper understanding of the role of consent legislation on donation and transplantation rates. The authors emphasize that countries implementing opt-out consent still face organ donor shortages, suggesting that changes to consent legislation or adopting aspects of the Spanish Model could potentially enhance donor rates.
Spain currently has the world's highest organ donation rate, attributed to measures such as a transplant coordination network functioning both locally and nationally, and an improvement in the quality of information regarding organ donation. As the organ shortage persists, discussions on alternative solutions like farming animal organs for human transplants continue to surface, but the focus remains on addressing this issue primarily through changes to organ donation policy.
