3. Per Med Definition in EU documents
• Personalised medicine refers to a medical model using
molecular profiling for tailoring the right therapeutic strategy
for the right person at the right time, and/or to determine the
predisposition to disease and/or to deliver timely and targeted
prevention
This is the EU H2020 definition of the Per Med.
4. For personalized medicine we’ll need:
E-infrastructure (e-health, digital prescriptions, digital signature,
electronic health records etc.)
Public support
Primary care providers support
Population based biobank
DNA analysis technology
Databases on genotype phenotype associations
5. Estonian Biobank
• Estonian Genome Center,
University of Tartu
• A prospective, longitudinal,
population-based database
with health records and
biological materials
• 52,000 participants - 5% of the
adult population of Estonia
• Individuals are recruited by
GPs, physicians in the hospitals
and medical personnel in the
EGCUT recruitment offices
• Estonian Human Genes
Research Act (HGRA)
6. § 3. Chief processor of Gene Bank
• (1) The chief processor of the Gene Bank is the University of Tartu,
whose objectives as the chief processor are to:
• 1) promote the development of genetic research;
• 2) collect information on the health of the Estonian population and genetic
information concerning the Estonian population;
• 3) use the results of genetic research to improve public health.

10. Estonian Government
• 16.12. 2014. the Cabinet approved the Pilot
Program of Personalized Medicine”
• Current government has “Personalized Medicine”
as one of its activities for the next period
• From 1.03.15. the Ministry of Social Affairs has a
new position “Deputy Secretary General for E-
services and Innovation”
12. The Estonian ID card
• The ID card is a mandatory ID document for all Estonian residents from the
age of 15
• Enables secure digital authentication and signing
• A digital signature has the same legal consequences
as a hand-written signature
• Does not have any additional information
– No bank account, no health information etc.
• Active cards: 1 214 428 (31.12.2013)
– Estonian Population 1 286 540 (01.01.2013)
– Estonia has been issuing electronic ID cards from January 1st 2002
– Also Mobile-ID

20. Polygenic risk scores: questions to address
• Which markers to include?
– We use 7500 independent markers for prediction of
genetic risk of Type 2 diabetes and 10200 markers for
Coronary Artery Disease
• Optimal weights?
- We show that optimal risk scores are obtained with double
weights: regression coefficients from a large-scale meta-
analysis are additionally weighted, to give more weight to
more significant markers (correction for „winners curse“)
21. Polygenic risk scores
Calculated as S = β1X1 + β2X2 + … + βkXk,
X2,…, Xk - allele dosages for k independent markers (SNP-s),
β1, β2, … , βk – weights

genetic risk

28. What is Clinical Decision Support Software
(CDSS)?
• CDSS provides clinicians with knowledge presented at
appropriate times
• It encompasses a variety of tools such as computerized alerts,
clinical guidelines, and order sets
• CDSS has the potential provide the necessary level of
personalized guidance to providers at the point of care that will
be necessary in the era of genomic medicine
• This is a tool to advise PCP (like radiology report)

The Estonian Program for
Personal Medicine I
31. Currently the pre-PILOT PROJECT is underway until
the end of June 2015. Then the pilot will last up to
2018.
The Estonian Program for Personal Medicine II
The precision medicine method should be seenbasic
as a additional “instrument” for physicians in
diagnosing, treating and preventing disease, but also
for research and clinical investigations, drug trials etc.

34. Evidence Generating Medicine
• The next step beyond
evidence-based medicine
• The systematic incorporation of research
and quality improvement considerations
into the organization and practice of
healthcare
• To advance biomedical science and thereby
improve the health of individuals and
populations.
35. Challenges and issues
• Awareness executives, doctors and patients
• New technologies and data empower patient
with more possibilities to manage own health
• Ethical issues
– Right to know and right not to know
– Treatable and non-treatable conditions
– Big data
• Not enough knowledge about associations
between DNA variants and diseases
• Large work-load to keep database of known
risk markers updated
36. Conclusions
• Estonia has great potential to plan and implement
personalized medicine solutions for the whole country,
starting with the pilot project for 50 000 gene donors
– Genetic research with 5% of population genetic and
continuously updated phenotype information
– Nation wide Health Information Exchange platform
– 10 years of experience of national level e-services (PKI, X-Road,
ID-card, security framework)
– High level public trust and acceptance
Estonian government:
25. We will establish a course towards personalised
medicine based on modern gene technology.
