ethics in nursing research

Overview of Ethical Issues in Health Care and Research

Importance of Ethical Discussions in Health Care Settings

  • Discussions of ethical issues were prominent in interviews conducted in the NICU, emphasizing the prevalence of ethical dilemmas in both early and end-of-life care.

  • Ethical issues are significant across all areas of nursing and healthcare, including research and evidence-based practice (EBP).

Constant Presence of Ethical Issues

  • Ethical concerns are ubiquitous in healthcare, impacting patient care, research, and EBP.

  • Ethical understanding is crucial in any discipline involving human or animal subjects in research.

  • Ethical standards exist to protect rights of participants in research and clinical practice.

Historical Context for Ethical Guidelines

  • Ethical guidelines have evolved over decades, particularly in response to historical abuses in research.

    • Nuremberg Code: Established post-World War II in response to Nazi medical experiments, aimed at protecting human research subjects.

    • Tuskegee Syphilis Study: A 40-year unethical study that disregarded patient protections, leading to widespread shock and outrage upon revelation.

  • Other atrocities in research history underscore the importance of ethical protections.

Key Ethical Codes and Frameworks

Nuremberg Code

  • The first framework aimed at protecting the rights of human subjects in research.

Declaration of Helsinki

  • Adopted in 1964 with multiple revisions, most recently in 2024, to protect subjects in non-therapeutic research (research without a therapeutic intervention).

American Nurses Association Code of Ethics

  • Revised recently, covering various provisions crucial for nursing practice, including:

    • Dignity and respect

    • Commitment to the recipient of care

    • Advocacy and accountability

    • Ethical work environments

    • Collaboration and social justice

Belmont Report

  • Formulated by the National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research.

  • Central principles:

    • Beneficence: Ethical obligation to “do no harm” and maximize benefits while minimizing risks.

      • Non-malfeasance: The obligation to minimize harmful impacts.

    • Respect for Human Dignity: Includes self-determination and full disclosure to participants.

      • Self-determination: Autonomy in deciding participation without coercion.

      • Full disclosure: Participants must be fully informed about the research.

    • Justice (Fair Treatment): Ensuring equity in participant selection and risk distribution, protecting vulnerable populations from exploitation.

Protecting Research Participants

Risk-Benefit Assessment

  • Ethical research requires a clear assessment of potential risks versus benefits for participants.

  • The risks involved should never outweigh the benefits.

  • Establishment of minimal risk in research studies, equating research risks to the risks of everyday life.

Informed Consent

  • Essential elements:

    • Detailed study information must be disclosed.

    • Consent must be voluntary and comprehensible, ensuring understanding of the study.

    • Protects privacy and should be accessible, accommodating reading levels and languages.

  • Vulnerable populations (e.g., children, mentally impaired individuals) require additional protections and considerations for consent.

Ethical Concerns in Research

Vulnerable Populations

  • Special considerations for groups such as:

    • Prisoners

    • Institutionalized individuals

    • Pregnant women

    • Children (need parental consent).

Conflicts of Interest

  • Included in research findings and publications, necessitating disclosure of any financial backing.

  • Potential for bias when funding comes from organizations with vested interests.

Importance of Institutional Review Boards (IRBs)

  • IRBs ensure ethical compliance in research involving human subjects.

  • Requirements for IRB approval cover risk management, informed consent processes, and privacy safeguards.

  • Types of IRB review:

    • Exempt: No risk; subject to minimal oversight.

    • Expedited: Minimal risk with expedited review.

    • Full review: Necessary for higher risk studies, especially with vulnerable populations.

Scientific Misconduct

Overview

  • Misconduct includes:

    • Fabrication: Making up results.

    • Falsification: Twisting facts or presenting them inaccurately.

    • Plagiarism: Misappropriating others' ideas or work.

  • Misconduct can lead to harmful findings and undermined trust in research integrity.

Case Study: Henrietta Lacks and HeLa Cells

  • Introduction to Henrietta Lacks, whose cancer cells (HeLa cells) were taken without her knowledge, leading to significant medical advances but ethical violations.

  • The ongoing ethical implications surrounding the use of her cells without consent, including the financial gains from research derived from her cells and the lack of compensation to her family.

Conclusion

  • Ethics in healthcare and research is vital and continues to evolve, especially in light of historical abuses.

  • Recognizing ethical principles aids nurses and healthcare professionals in providing safe and equitable care to all patients, ensuring that research is conducted ethically and transparently.

  • The story of Henrietta Lacks serves as a reminder of the importance of informed consent and ethical considerations in all aspects of medical research and practice.
