Losing the balance in risk-benefit analysis

Area of Science:

• Radiological Protection
• Medical Physics
• Risk Assessment

Background:

• Benefit-risk analysis is a long-standing concept, yet its balance can be lost, leaning towards benefit alone (medicine) or risk alone (nuclear industry).
• Public perception significantly influences the balance, as seen in medicine's tendency to overlook long-term risks for immediate benefits and the nuclear industry's focus on accidents over benefits.
• Tissue reactions in fluoroscopic interventions are often highlighted, despite potentially lower stochastic radiation risks compared to other factors.

Purpose of the Study:

• To examine instances where the balance in benefit-risk analysis is lost, particularly in medical exposures.
• To draw parallels between risk assessment in pharmaceuticals and radiation safety.
• To motivate the International Commission on Radiological Protection (ICRP) to develop solutions for managing immediate benefits against long-term radiation risks in medical contexts.

Main Methods:

• Conceptual analysis of benefit-risk assessment principles.
• Review of case examples in medicine (e.g., fluoroscopy) and the nuclear industry.
• Analogy drawn from pharmaceutical risk management systems.

Main Results:

• Benefit-risk balance is susceptible to cognitive biases and public perception, leading to disproportionate focus on either benefits or risks.
• Medical exposures, particularly those with immediate benefits and uncertain long-term radiation risks, exemplify this imbalance.
• Existing frameworks for drug risk management offer potential lessons for radiological protection.

Conclusions:

• The intuitive nature of benefit-risk analysis can mask significant imbalances, necessitating a more rigorous and balanced approach.
• There is a clear need for the ICRP to address situations involving immediate medical benefits and long-term radiation risks.
• Learning from other fields, like pharmaceuticals, can enhance strategies for managing radiation risks in medical procedures.
