Which of the Following Brought Increased Public Attention to the Problems with the IRB System?

Institutional Review Boards (IRBs) are essential for ensuring the ethical conduct of research involving human subjects. Despite their crucial role, the IRB system has faced significant scrutiny and criticism. This article delves into the key events, systemic issues, and reform efforts that have highlighted the problems within the IRB system and brought them to public attention.

The Role and Importance of IRBs

Historical Context and Ethical Mandate

IRBs were established to address historical abuses in medical and psychological research, such as the Tuskegee Syphilis Study and the unethical experiments conducted by Nazi doctors during World War II. These atrocities underscored the necessity for ethical oversight in research involving human subjects. The Belmont Report, published in 1979, laid the foundation for modern IRB practices by emphasizing the principles of respect for persons, beneficence, and justice.

Core Functions and Responsibilities

IRBs are responsible for:

  • Reviewing research proposals to assess potential risks and benefits.
  • Ensuring informed consent is obtained from participants.
  • Monitoring ongoing research to ensure compliance with ethical standards.
  • Protecting vulnerable populations from exploitation.

Despite their vital role, IRBs have faced numerous challenges, leading to public and professional scrutiny.

High-Profile Incidents Highlighting IRB Failures

The Jesse Gelsinger Case

One of the most significant cases that brought attention to the problems within the IRB system was the death of Jesse Gelsinger in 1999. Gelsinger, an 18-year-old with a genetic disorder, participated in a gene therapy trial at the University of Pennsylvania and died due to complications from the treatment.

Ethical Breaches and Oversight Failures

Investigations revealed that researchers failed to disclose severe side effects observed in prior animal and human studies. This tragic incident highlighted serious flaws in the IRB approval process, including inadequate disclosure of risks and potential conflicts of interest, as the lead researcher had financial ties to the success of the study.

The Havasupai Tribe Case

Another critical incident involved the Havasupai Tribe, a Native American community in Arizona. Members of the tribe provided blood samples for diabetes research in the 1990s. However, these samples were later used without their consent for studies on mental illness, migration, and inbreeding.

Breach of Trust and Ethical Violations

This case exposed significant failures in the informed consent process and a lack of cultural sensitivity. The tribe sued Arizona State University, leading to a settlement that included financial compensation and the return of the blood samples. This incident emphasized the necessity for IRBs to enforce rigorous consent procedures and respect cultural values.

Systemic Challenges Facing IRBs

Inconsistent Standards and Procedures

A major challenge within the IRB system is the lack of uniform standards and procedures across different institutions. This inconsistency can result in varying levels of ethical scrutiny and oversight.

Fragmented Oversight

IRBs operate independently at various institutions, leading to a fragmented system. This can cause differing interpretations of ethical guidelines and variability in the rigor of the review process. For researchers, navigating these inconsistencies can be frustrating and may hinder scientific progress.

Resource Constraints

Many IRBs are struggling with increasing workloads and limited resources. The growing volume of research proposals can overwhelm these boards, leading to rushed reviews and potential oversights.

Impact of Overload

An overburdened IRB may fail to thoroughly review each proposal, increasing the risk of ethical lapses. Additionally, under-resourced IRBs may lack access to necessary expertise, further compromising their ability to protect research participants effectively.

Conflicts of Interest

Conflicts of interest within IRBs can undermine their integrity. Board members may have financial or professional ties to the research they review, leading to biased decisions.

Ensuring Independence

Maintaining public trust in the IRB system requires addressing conflicts of interest and ensuring that board members are impartial and focused solely on protecting participants.

Efforts to Reform the IRB System

Enhancing Transparency and Accountability

One key recommendation for reform is increasing transparency and accountability within the IRB system. This includes clearer documentation of the review process and making information about IRB decisions publicly accessible.

Public Access to IRB Activities

Providing public access to IRB meeting minutes and decisions can build trust and ensure that the board’s actions align with ethical standards. Transparency can also facilitate external oversight and encourage continuous improvement.

Standardizing Procedures

Standardizing IRB procedures across institutions can help address inconsistencies and ensure uniform scrutiny of research proposals.

National and International Guidelines

Adopting national and international guidelines can harmonize IRB processes and reduce fragmentation. Organizations like the Office for Human Research Protections (OHRP) in the United States play a crucial role in developing and enforcing these standards.

Improving Resources and Support

Providing IRBs with adequate resources and support is essential for their effective functioning. This includes financial resources and access to training and expertise.

Training for IRB Members

Continuous training and education for IRB members can ensure they are well-equipped to evaluate complex research proposals. Staying updated on ethical guidelines, emerging technologies, and cultural considerations is vital.

The Role of Public Awareness and Advocacy

Media Coverage and Public Discourse

Media coverage of high-profile cases and ethical lapses has been instrumental in drawing attention to the problems within the IRB system. These stories can spark public discourse and pressure institutions to address shortcomings.

Investigative Journalism

Investigative journalism has been particularly effective in uncovering ethical violations and conflicts of interest. By highlighting these issues, journalists can hold institutions accountable and push for necessary changes.

Advocacy by Research Participants and Communities

Research participants and their communities can advocate for better protections and ethical standards. By sharing their concerns and experiences, they can influence policy changes and ensure that their rights are respected.

Grassroots Movements

Grassroots movements and advocacy groups have successfully campaigned for stronger protections and greater transparency in research. These efforts can lead to meaningful policy changes and improvements in the IRB system.

Future Directions for IRB Oversight

Embracing Technological Advances

Technological advances can offer new tools and methods for improving IRB oversight and efficiency. Digital platforms can streamline the review process and facilitate better communication between IRBs and researchers.

Big Data and AI

Big data and artificial intelligence (AI) can help identify patterns and potential risks in research proposals. These technologies can assist IRBs in making more informed decisions and enhancing their ability to protect participants.

Fostering a Culture of Ethical Research

Promoting a culture of ethical research requires a collective effort from researchers, institutions, and IRBs. This includes encouraging transparency and prioritizing participants’ welfare.

Education and Ethical Training

Incorporating ethics education and training into the curriculum for researchers and IRB members can help instill a strong commitment to ethical practices. Continuous education is vital for adapting to new ethical challenges and evolving standards.

Collaborative Approaches

Collaboration between institutions, regulatory bodies, and advocacy groups can lead to more effective oversight and better protection for research participants. Working together, these stakeholders can address systemic issues and promote ethical research practices.

Global Cooperation

Global cooperation and the adoption of international standards can help harmonize ethical oversight and ensure consistent protections for research participants worldwide. This can also facilitate cross-border research and collaboration.


The IRB system has faced increased public scrutiny due to high-profile cases, systemic challenges, and rising public awareness. While these issues highlight significant shortcomings, ongoing efforts to improve transparency, standardize procedures, and enhance resources provide hope for a more effective and ethical framework.

By understanding the issues and advocating for change, we can help build a better IRB system that truly protects the rights and welfare of research participants. Whether you are a researcher, participant, or concerned citizen, your engagement and advocacy can contribute to a more ethical and trustworthy research environment. Let us work together to ensure that the IRB system fulfills its vital role in safeguarding human subjects in research.
