Conceptual issues for screening in the genomic era - time for an update?

Area of Science:

• Medical Ethics
• Public Health Policy
• Genomic Medicine

Background:

• A clear consensus on criteria distinguishing screening from clinical testing is lacking.
• Varied definitions cause confusion among healthcare professionals.
• Genomic advancements necessitate a clearer understanding of screening.

Purpose of the Study:

• To evaluate concepts differentiating screening from clinical testing.
• To investigate the ethical implications of screening versus clinical testing.

Main Methods:

• Conceptual analysis of screening and clinical testing definitions.
• Ethical implications assessment.

Main Results:

• Screening involves asymptomatic individuals, generally offered to those healthy for the specific disease.
• Other screening characteristics are practical requirements or by-products, not core definitions.
• Two key concepts define screening: asymptomatic status and proactive offering.

Conclusions:

• Differentiating opportunistic screening from clinical testing is vital due to differing disease probabilities.
• Physicians face distinct ethical and legal obligations in screening versus clinical testing scenarios.
• Understanding the shift in moral burden is essential for medical practice.
