Overdiagnosis

Overdiagnosis is one of the challenges following medical uncertainty. Detecting conditions, processes, or states that can develop to disease without knowing whether they do so, poses some basic problems for modern medicine.

About the project

Overdiagnosis is one of the challenges following medical uncertainty. Detecting conditions, processes, or states that can develop to disease without knowing whether they do so, poses some basic problems for modern medicine: 

  • What are such states? (This represents ontological challenges)
  • How can we gain knowledge about such states? (This represents epistemological challenges)
  • What should we do with such states? (Should we diagnose, inform about, and treat them?) (This represents ethical challenges)

Objectives

To investigate conceptual, ontological, epistemological, and ethical aspects of overdiagnosis. 

Methods

Conceptual, epistemological, and ethical analysis of overdiagnosis. 

Financing

Part of the project has been financed by the Norwegian Research Council, of the Harkness Fellowship, part of the project has been financed by the Commonwealth Fund, and a small part of the research has been financed by the Brocher Foundation (as a research stay in Hermance April 2018). 

Cooperation

Dartmouth College, NH, USA.
