The right to know from the opt-out effectiveness system perspective in organ transplantation cases.

Objective: Aim: This article examines the legal challenges associated with opt-out and opt-in systems in transplantation cases. It focuses on the low public knowledge and awareness of the national transplantation system, assessing its compliance with international prerequisites for an opt-out system. The analysis centres on the "right to know" perspective and the effectiveness of opt-out in organ transplantation. .

Patients and methods: Materials and Methods: The research methodology includes scientific principles, public surveys, relevant regulations from the Republic of Latvia and EU, and grey literature on the health system and organ donation in the EU. Scientific articles from databases such as Scopus and WOS were selected based on criteria such as language (English and Latvian) and focus on living wills and comparisons of organ donation systems. Previous EU and national studies, reports, and court judgments were used to analyse data on opt-in and opt-out transplantation systems and policy efficiency in organ transplantation.

Conclusion: Conclusions: Individuals' right to autonomy over their bodies extends even after death, encompassing the right to integrity. Organ donation, being a deeply personal choice reflecting one's values and beliefs, plays a crucial role in saving lives through transplantation. To enhance cooperation and donation rates, international regulations stress the significance of public awareness regarding organ and tissue transplantation. Unfortunately, inadequate compliance by authorities and low awareness pose ethical and legal dilemmas, potentially violating constitutional rights. Reports highlight limited public understanding of transplantation systems, raising concerns, particularly in opt-out systems. National governments bear the responsibility of safeguarding these rights and addressing challenges beyond legal means, thus establishing a more ethical organ donation system that upholds voluntariness, generosity, and individual autonomy.
