Consent Model, Opt-in/Opt-out System, and Organ Donation Rates in European Union Countries
Keywords:Tissue and Organ Procurement; Donation Consent; Donor Selection
Introduction:Disparities in organ donation rates exists through the world countries, even despite sharing a common legislative background. The model of the consent for organ donation after brain death (deceased donor) informed consent (opt-in system) or presumed consent (opt-out system), influences the rates of organ donation. Opt-out legislative systems claim to dramatically increase effective organ donation consent rates. There is no evidence that opt-out system is the sole factor. A variety of other factors may interact and modify the system’s effect on donation rates. Materials and methods:Secondary data analysis using the european annual reports from International Registry On Organ Donation and Transplantation (IRODaT) for the years 2013-2017 through descriptive and inferential statistics, Levene’s test for equality of variances was used to measure the statistical difference between opt-in and opt-out system donation rates. Comparisons were made between all 28 EU countries from the perspective of the consent systems. For this study, we choose to compare the donation rate per million population (pmp) and actual deceased donors between EU countries with opt-in consent system, 8 countries (28.58%): Denmark, The Netherlands, Germany, Romania, UK, Ireland, Lithuania, Malta, and countries with opt-out consent system, 20 countries (71,42%): Sweden, Poland, Austria, France, Spain, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Estonia, Finland, Greece, Hungary, Italy, Latvia, Luxembourg, Portugal, Slovakia, Slovenia. Results: In opt-out system countries resulted a mean value of 20.39 pmp, and in the opt-in countries resulted a mean value of 15.97. The result of the applied test demonstrates that there is no statistically significant difference (p>0.05). Conclusion: Opt-out consent may lead to an increase in deceased donation but it is also important to assess other factors that influence organ donation system.
