Non-completion and informed consent.

Area of Science:

• Biomedical research ethics
• Clinical trial recruitment

Background:

• Many biomedical studies fail due to insufficient participant recruitment, compromising data utility.
• Current informed consent processes prioritize self-interested decisions, neglecting altruistic considerations.
• The "completion misconception" in bioethics, unlike the "therapeutic misconception," remains largely unaddressed.

Purpose of the Study:

• To argue for the inclusion of non-completion possibility in informed consent for clinical trials.
• To establish criteria for when non-completion information is relevant for prospective participants.
• To address potential objections to disclosing non-completion data.

Main Methods:

• Ethical argument analysis
• Review of existing consent guidelines
• Consideration of bioethical principles

Main Results:

• Non-completion information should be disclosed if non-trivial and relevant to participant decision-making.
• Standard consent procedures often omit crucial data for altruistic choices.
• Disclosure may face challenges related to recruitment difficulties.

Conclusions:

• Informed consent must evolve to encompass altruistic decision-making factors.
• Transparency regarding potential non-completion enhances ethical research conduct.
• Addressing the "completion misconception" is vital for participant autonomy and research validity.
