Healty Ageing

Challenges and opportunities of

BIG DATA

• Generic issues

– DATA + BIG

And

• Healthy ageing – related issues

– DATA + BIG + Health -> eHealth

Data heterogeneity

• Data from multiple devices, captured in many

ways, in space and time

OPPORTUNITY –

complementarity helps

discovery

PROBLEM - how to

integrate very different

data for many

perspectives

Interoperability across systems

• Hospitals, clinics, research centers want to

share data

OPPORTUNITY – data

sharing helps discovery

PROBLEM - exchange

data and preserve

confidentiality

PROBLEM – E H R

standards

Data curation and preservation

• Maintain data for (unimaginable) future uses

OPPORTUNITY –

longitudinal studies

PROBLEM - cost,

data decay,

technology decay

Data curation and preservation

HEALTHY AGEING STUDIES

REQUIRE

DATA THAT AGE HEALTHILY

Security and privacy

• Maintain data free from attacks and

inadvertent disclosure

OPPORTUNITY – preserve

quality and integrity

PROBLEM - hampers

sharing

PROBLEM – differential

privacy

Data ethics and ethical algorithms

• New field in Computer Science

TRENDS – human values, and machine issues

PROBLEM - new procedures from Ethics

committees

From Globalized to Personalized

Medicine
