Consent for research with biological samples: one-time general consent versus a gift model

Area of Science:

• Bioethics
• Biomedical Research
• Data Management

Background:

• Obtaining and storing human biological samples for future research presents complex ethical and logistical challenges.
• Current models for consent and sample handling may not adequately address these multifaceted issues.
• The need for robust frameworks governing biobanking is critical for advancing scientific discovery.

Purpose of the Study:

• To analyze the efficacy of different consent models for the long-term storage of human biological samples.
• To compare the 'one-time general consent' model against the 'gift model' in addressing key challenges in biobanking.
• To provide evidence-based recommendations for regulatory updates concerning human biological samples in research.

Main Methods:

• Comparative analysis of consent models for human biological sample research.
• Evaluation of the 'one-time general consent' and 'gift' models against five central challenges.
• Review of existing regulatory frameworks and proposed changes.

Main Results:

• The 'one-time general consent' model demonstrates superior performance in managing the challenges associated with obtaining and storing human biological samples.
• The 'gift model' presents significant limitations in addressing these identified challenges.
• Analysis indicates that one-time general consent is a more effective strategy for future research endeavors.

Conclusions:

• One-time general consent is the preferred model for ethical and practical considerations in biobanking.
• The findings support the integration of one-time general consent into federal regulations for research involving human biological samples.
• Adopting this model will enhance the responsible and efficient use of valuable biological resources for scientific advancement.
