Australian Perspectives on Opt-In and Opt-Out Consent Systems for Deceased Organ Donation.

As many countries change to opt-out systems to address organ shortages, calls for similar reform in Australia persist. Community perspectives on consent systems for donation remain under-researched, therefore Australian perspectives on consent systems and their effectiveness in increasing donation rates were explored. In this descriptive cross-sectional study, participants completed a survey presenting opt-in, soft opt-out, and hard opt-out systems, with corresponding descriptions. Participants chose the system they perceived as most effective and described their reasoning. Participants (N = 509) designated soft opt-out as the most effective system (52.3%; hard opt-out 33.7%; opt-in 13.7%). Those who identified with an ethnic/cultural group or were not registered had greater odds of choosing opt-out. Six themes identified in thematic analysis reflected their reasoning: (1) who decides (individual, shared decision with family); (2) right to choose; (3) acceptability (ethics, fairness); and utility in overcoming barriers for (4) individuals (apathy, awareness, ease of donating, fear/avoidance of death); (5) family (easier family experience, family veto); (6) society (normalizing donation, donation as default, expanding donor pool). Choice and overcoming individual barriers were more frequently endorsed themes for opt-in and opt-out, respectively. Results suggested the following insights regarding system effectiveness: uphold/prioritize individual's recorded donation decision above family wishes; involve family in decision making if no donation preference is recorded; retain a register enabling opt-in and opt-out for unequivocal decisions and promoting individual control; and maximize ease of registering. Future research should establish whether systems considered effective are also acceptable to the community to address organ shortages.
