What is the role of informatics in PPPM?
• Informatics is both an enabler and driver in PPPM. Advances abound in
informatics and biological research but practical PPPM is in its infancy
and there is a disconnect in most health systems – especially with their
information systems
• Although challenging enough, more is required than bridging
bioinformatics and medical informatics – there is a need for high level
planning and co-ordination of informatics for PPPM
• The knowledge, work practices and informatics of laboratory medicine
must be more engaged for PPPM to meet its potential – sensitivity,
specificity and quality systems remain important
• More standardisation of health information, knowledge and informatics is
needed for discovery and for PPPM to be effective, efficient and safe
• Education in informatics and more specialist informaticians are needed
14-15 October 2013 National Pathology Forum 19
Informatics is central to proactive healthcare
It is needed to:
• Undertake the analysis of bio data, information and knowledge related
to molecular medicine and its links to disease for discovery and
service delivery
• Gather and synthesise inputs from machines and people for optimal
clinical decisions
• Engage consumers and provide the information and tools they need
to make decisions and change behaviours
• Learn from what has happened at the individual, process and health
system levels
• Manage the information and knowledge that health workers need to
make their jobs safer and easier
• Facilitate standardisation and remove inappropriate variation

But we have some challenges
• We don’t have a shared understanding even of what constitutes the
domain of informatics in health or what to call its components
• The domain of informatics used for recording, analysing,
communicating and doing the business of healthcare I call health
informatics
• The domain of informatics used to unravel and understand the
molecular and cellular workings of biology I call bioinformatics
• In most places these domains are still operating in separate
universes
• After 50 years we are only just starting to realise health informatics
and we have only just commenced integrating that with
bioinformatics
14-15 October 2013 National Pathology Forum 22
Biomedical informatics and
personalised medicine
In Europe the informatics gap between bench and bedside is being
addressed by INBIOMEDvision through think-tanks and publications on
the themes
• Genotype-phenotype integration
• Re-use of clinical information for research
• Translational systems biology and bioinformatics
• Horizontal aspects
They call this work biomedical informatics
14-15 October 2013 National Pathology Forum 23
Genotype-phenotype integration
Trends
• To develop validated repositories and standards
• To develop specific tools and resources for proof of concept in
areas like rare diseases to gain clinicians trust
• To develop tools and resources based on genotype-phenotype
associations for patient stratification in clinical trials
14-15 October 2013 National Pathology Forum 24
Genotype-phenotype integration
Challenges
• Genotype-phenotype knowledge is large, complex, prone to
errors, and has small effects and uncertain conclusions
• Genotype-phenotype research data are not suitable for
packaging and display for clinical application or training
• Doctors are uninformed about the nature, limitations and
potential of modern genotype-phenotype knowledge
• Failure to discriminate between scenarios where molecular data
can be ‘predictive’ as opposed to risk modifying
14-15 October 2013 National Pathology Forum 25
Re-use of clinical information for research
Trends
• To propose few standards in the beginning and allow them to
evolve pragmatically
• To digitalise and standardise data capture to allow better quality
and optimisation for sharing and re-use for research
• To increase automation of data entry to facilitate clinicians and
clinical communities work
• To involve clinicians from different lines of work
• To promote projects for capturing clinical data that might be used
worldwide across regional and country boundaries and between
hospital and community settings
14-15 October 2013 National Pathology Forum 26
Re-use of clinical information for research
Challenges
• To unify and standardise items in the EHR
• To determine the minimum data to include ensuring better
quality of data entry or capture
• To ensure better interoperability of IT
• To incorporate new types of data (environmental, complete
genomes etc)
• To promote unification of regulations for EHR (legal, ethical,
security confidentiality)
• To study quality assurance especially in the analysis of
retrospective clinical data
14-15 October 2013 National Pathology Forum 27
Translational systems biology and
bioinformatics
Trends
• To standardise methodologies
• To standardise database formats
• To apply crowd-sourcing and collaborative-competition in
systems biology
14-15 October 2013 National Pathology Forum 28
Translational systems biology and
bioinformatics
Challenges
• To analyse high throughput studies (GWAS, PheWAS, EWAS)
to obtain bioinformatics signatures in molecular diagnostics,
prognostics, drug response and drug discovery
• To establish reliable and reproducible computational models
(molecular, cellular, organism, organ and population level)
14-15 October 2013 National Pathology Forum 29
Horizontal aspects
Trends
• To develop standards
• To retrieve and analyse data using data text mining and
semantic tools
• To retrieve information from population-based data mining
• To use cloud computing
• To design training programs for clinicians
• To develop patient-oriented tools for data sharing and patient
empowerment
• To promote collaboration between communities
(research/clinic/industry)
14-15 October 2013 National Pathology Forum 30
Horizontal aspects
Challenges
• Data management and integration
• Data security
• User interfaces
• Socioeconomic challenges
• Openness and sharing of information
• Physician education and training
• Patient empowerment
• Industry-academy collaboration
• Intellectual property
14-15 October 2013 National Pathology Forum 31
There is an elephant in the room
14-15 October 2013 National Pathology Forum 32
We don’t have the standards,
infrastructure or people
• There are massive storage and analysis requirements - much more
than generally recognised - the human pangenome at 1024 bytes is
1000 times all current world storage. As the number of sequenced
genomes increases, storage capacity will become limiting
• The current approach of diagnostic laboratories to genomic
medicine is unsustainable
• The healthcare related scientific community has too few
informaticians and unfortunately many of those that we do have are
without the breadth of understanding of the field to make the kind of
advances that are needed. This is well illustrated by the existing gulf
between health and bio-informaticians
14-15 October 2013 National Pathology Forum 33
Informatics standards
The only way forward is to agree what we will keep and how - but after
more than 20 years of standards development work there is no widely
accepted and adopted standards for:
• Grammar to communicate health care information – despite
progress with standards like HL7v2.x and CDA
• Information structures – despite progress with models like
HL7v3-RIM and OpenEHR
• Terminology – despite progress with SNOMED, LOINC, HUGO
and many others
• Rules and knowledge – despite progress with Arden Syntax,
GELLO and others
14-15 October 2013 National Pathology Forum 34
In short…
More than ten years after sequencing the
human genome we do not have the
knowledge, education or informatics tools to
implement clinical genetics, genomics,
proteomics, metabolomics or epigenetics
into practical personalised medicine
14-15 October 2013 National Pathology Forum 35
Science and innovation is the answer to the
looming threat to sustainable healthcare
14-15 October 2013 National Pathology Forum 36
What needs to happen…
• Informatics for PPPM has to be seen as a discipline in its own
right and be a research and education theme
• Work on integrative informatics has to be done globally and that
will require planning and engagement with the standards
development organisations
• Progress will require action based research using prototyping
and agile development in a real-world provider network
• Standardisation could start with existing registries and their
feeds
14-15 October 2013 National Pathology Forum 37
What are the benefits for patients and
healthcare?
• Digitisation of biology and health – will allow machines to help in discovery and delivery
– lead to a demystification of disease,
– the democratisation of healthcare
– and allow us to move from the treatment of disease to the
promotion and maintenance of wellness
• Digital technology has disrupted other sectors – medicine is
unlikely to remain immune from this
