Ethics in research with vulnerable human subjects: a review study

Area of Science:

• Bioethics
• Clinical Research Ethics
• Public Health

Background:

• Vulnerable populations often face compromised rights during research recruitment.
• Ensuring ethical conduct and justice for vulnerable groups in research is a significant challenge.
• Existing knowledge on research ethics with vulnerable populations requires comprehensive analysis.

Purpose of the Study:

• To analyze existing knowledge on research ethics concerning vulnerable populations.
• To identify key themes related to ethical challenges and protections for vulnerable research participants.
• To contribute to enhanced protection and justice for vulnerable individuals in research settings.

Main Methods:

• Systematic literature search conducted on PubMed and VHL databases.
• Keywords used: "Ethics, research" AND "Vulnerable populations" over the past ten years.
• Thematic content analysis performed on 33 selected articles after initial screening of 240 studies.

Main Results:

• Three primary themes emerged: vulnerability versus justice, coercion/exploitation/ethics dumping, and challenges/barriers to ethical research.
• Analysis revealed significant issues in protecting the rights and ensuring fair participation for vulnerable individuals.
• Identified specific areas requiring attention for ethical research conduct.

Conclusions:

• Ethical research with vulnerable populations necessitates improved international standards.
• Consideration of individual particularities and contextual factors is essential for participant protection.
• Strategies must be developed to ensure access to optimal treatment and minimize vulnerabilities in clinical trials.
