ODx

03.10.16 University of Zurich, IBME, Overdiagnosis and Big Data, Corine Mouton Dorey Page 8

Big data could help recognize and reduce ODx

-  Stratifying patients and relative outcomes -  Linking datasets -  Prophetic correlations -  Investments

Page 9: Overdiagnosis and Big Data: An ethical perspective · 03.10.16 University of Zurich, IBME, Overdiagnosis and Big Data, Corine Mouton Dorey Page 10 . 03.10.16 University of Zurich,

03.10.16 University of Zurich, IBME, Overdiagnosis and Big Data, Corine Mouton Dorey Page 9

Big Data could favour the drivers of ODx

-  Multiple actors & more COI -  Translational uncertainty -  Expanded disease borders -  Lack of digital literacy -  Opportunity cost

Paradox

The risk of ODx:

Precise/target medicine ( based on big data) (morally good)

leads to inappropriate treatment (morally wrong)

How to use Big Data to resolve this moral paradox?

Narrative approach: a lens to analyse our story

-  We are in a story (descriptive) -  But how can we understand that story? (mattering map)

-  We need to interpret it (correlations)

Page 13: Overdiagnosis and Big Data: An ethical perspective · 03.10.16 University of Zurich, IBME, Overdiagnosis and Big Data, Corine Mouton Dorey Page 10 . 03.10.16 University of Zurich,

How interpretation helps for medical judgement?

-  The interpretation reveals the identity of the character of the story E.g. Patient – Physicians

-  Narrative identities help understand what matters morally (normative)

Paul Ricœur (1913-2005)

03.10.16 University of Zurich, IBME, Overdiagnosis and Big Data, Corine Mouton Dorey Page 14

Page 15: Overdiagnosis and Big Data: An ethical perspective · 03.10.16 University of Zurich, IBME, Overdiagnosis and Big Data, Corine Mouton Dorey Page 10 . 03.10.16 University of Zurich,

03.10.16 University of Zurich, IBME, Overdiagnosis and Big Data, Corine Mouton Dorey Page 15

Narrative identities: individual and collective

Selfhood “who I am”

Sameness “what I am”

2 poles in the narrative identity:

03.10.16 University of Zurich, IBME, Overdiagnosis and Big Data, Corine Mouton Dorey Page 16

Ricœur’s ethics aims at:

“a good life, with and for others, in just institutions”

Self Others Society

Ricœur’s 3 propositions for medical judgment

Anterior Ethics

Morality Norms

Posterior Ethics

“Ricœurian” matrix for Big Data to reduce ODx

Big Data î ODx

Anterior ethics Morality norms

Posterior ethics “Applied to Medical

judgment”

Self Self-esteem Virtues Standard of excellence

Self-respect Autonomy Free choice

Trust agreement: decision Patient agency Physician accountability

Others Solicitude Benevolent sharing

Respect for others Reciprocity Benevolence as no harm

Medical contract Confidentiality Professional codes Trustworthiness

Society Sense of justice Living together Equality Sharing and Repairing

Distributive justice Legal authority Legitimacy (testing, screening, and commercialization)

Research goals aligned with common good Solidarity, digital literacy Prudence Equity in access to big data

Ethical recommendations require political will

1.  Clarifying accountability when medical judgment is based on big data information.

2.  Reducing asymmetry in digital literacy between citizens, patients and care providers (patient information, education)

3.  Continue research and innovative queries looking for evidence on big data and ODx.

4.  Sharing governance between experts, policy-makers, clinicians and patients.

-  Transparency, access to algorithms

-  Democratic deliberation on common good

-  Compensation for harm due to ODx
