Forensic Epidemiology in Italy: principles and practice.

Area of Science:

• Forensic epidemiology
• Public health law
• Causal inference

Background:

• Forensic epidemiology (FE) bridges epidemiology and legal proceedings, requiring skilled experts to interpret data for judicial purposes.
• The need for FE has grown, particularly in the Italian context, due to increasing legal cases requiring assessment of disease causation.
• Key figures like Rothman and Bradford Hill have shaped the understanding of causality, forming the basis for FE principles.

Purpose of the Study:

• To describe the principles and applications of forensic epidemiology within the Italian legal system.
• To highlight the growing demand for trained epidemiological experts in judicial settings.
• To underscore the importance of FE in establishing causal associations in complex legal cases.

Main Methods:

• Review of established epidemiological principles for causal association assessment.
• Examination of legal proceedings requiring epidemiological expertise.
• Illustration of FE applications using real-world examples, such as environmental pollution and disease.

Main Results:

• FE principles, grounded in epidemiological methods, are fundamental for evaluating legal matters concerning disease causation.
• Assessing causal associations in legal contexts is often complex, with frequent ambiguities and discordant arguments.
• The expertise of epidemiological professionals and robust study designs are vital for resolving discrepancies between clinical and epidemiological data.

Conclusions:

• Forensic epidemiology plays a critical role in the Italian legal system for determining causal links between exposures and diseases.
• Experienced epidemiologists are essential for navigating legal proceedings and providing expert testimony.
• Well-designed epidemiological studies and expert interpretation are crucial for robust causal assessments in civil and criminal matters.
