Medicalization and overdiagnosis: different but alike

Area of Science:

• Medical Sociology
• Health Policy
• Clinical Epidemiology

Background:

• Medicalization broadens disease concepts by framing non-medical issues as health problems.
• Overdiagnosis involves identifying conditions that wouldn't cause harm without testing.
• Both concepts critique the expansion of medicine and contested health services.

Purpose of the Study:

• To clarify the distinctions between medicalization and overdiagnosis.
• To analyze the differing subject matter and types of uncertainty associated with each concept.
• To examine the evolving relationship and potential convergence of medicalization and overdiagnosis.

Main Methods:

• Conceptual analysis of medicalization and overdiagnosis.
• Comparative examination of their traditional subject matter (social vs. biological).
• Discussion of differing types of uncertainty (indeterminacy vs. prognostic knowledge).

Main Results:

• Medicalization traditionally addresses social/cultural phenomena, while overdiagnosis focuses on potentially harmful biological processes.
• Medicalization relates to sickness (sick role), whereas overdiagnosis pertains to disease.
• Both concepts are converging, with medicalization incorporating technical aspects of overdiagnosis and vice versa.

Conclusions:

• Despite differences, medicalization and overdiagnosis are increasingly similar, potentially leading to a loss of critical distinction.
• Future trends like P4 medicine may further blur these lines, leading to all-encompassing medicalization.
• The convergence risks creating 'iatrogenization' and diminishing the critical utility of these concepts.
