The Chair of the openEHR Foundation has taken a few days to recharge and develop a thought or two on international standards in health informatics. This is well worth reading and thinking about.
There are additional events occuring at this time that might be considered to support this position. Please see the “Detailed Clinical Models”:http://detailedclinicalmodels.org/wiki/index.php?title=Main_Page (DCM) event documents and Wiki.

Below you will find a thought provoking commentary from the Chair of openEHR.

—————————————————-

I returned from a week of sailing to discover flames leaping from
the openEHR list server in the machine room opposite my office! I�m with
many recent correspondents on the lists in welcoming the positive side
of the debate whilst regretting some of the evidence of raw feelings in
play. I�m sure many are wondering or reflecting on what this is all
about. From my perspective, there�s no need for a lot of new words
about openEHR and HL7, per se, but a great need to keep hearts and minds
in good shape for clarifying, understanding and learning from one
another. openEHR is a truly open community; anyone can take its
published outputs and do what they want with them; but their integrity
and that of the community, brand, and methodology of openEHR must be
protected and maintained, we believe. Please keep in mind the words that
all sign up to when joining openEHR and its lists and downloading its
materials.

That said, I know that good things can happen where extreme difference
of view and even animosity is in play. I learned that from seeing a lot
of the action, as a very junior committee member, in the early days of
Amnesty International in the mid 60�s. The offices of the then tiny, but
already strikingly influential, organisation were raided by the secret
police of various countries. But these events felt as nothing compared
with the fights among the visionaries within the movement who were
determined in quite different ways on their view of how the quest for
freedom of expression under the UN Charter, on which all were united,
should be framed and pursued!

�Never helps hone� is an anagram of the letters in openEHR and HL Seven!
In my experience, an imposed drive for unity never helps hone good and
enduring answers to problems; finding common mission can and does but we
mustn�t forget that there is strength in diversity and that monopolistic
tendency may serve some interests but, equally, carry with it the
potential for weakening or corrupting others. I�m writing here as
someone a bit removed from the heat of the crucible of EHR
implementation and standardisation, who, nonetheless, sees and hears,
from colleagues and students on the front line, many inner details of
what is playing out. From the policy to the practice of health care
modernisation and in the creation of new health care information
infrastructure, in many countries, the debate ongoing through
the openEHR lists is becoming a central concern. That�s a good thing; a
very good thing. For too long the issues have been delegated or
relegated unduly far from the clinical domain and into the domains of
engineering and organisation. Unfulfilled aspiration for health IT has
created a poker game of ever increasing stakes of ambition, resource and
emotion, drawing in an ever wider range of stakeholders, to the top
policy levels. Just look at the Commonwealth Fund web site in the States
or view on the web the recent Public Accounts Committee hearing on CfH,
in the UK.

I�ve been around the debate a long time and have learned that the three
things that matter, as I�ve said before, are implementation,
implementation and implementation! The problem with standardising, top
down, before doing, is that one tends never to have time to do, and
learn well through doing. The problem with doing, bottom up, before
learning how to standardise, is that one tends to spend a lot too much
time and money, creating eventual ultimate havoc of incompatible legacy.
This complexity can only be reduced to tractable levels through starting
again, while problems of integration remain elusive. I see the waste and
despair that creates in the healthcare workforce. It�s a Catch 22; I can
chart five reinventions of a national programme for IT, within the NHS,
in my career.

At its heart, all of this is a debate about emerging discipline, notably
in medicine and computer science and at their interface. It�s hard
because that discipline has been sorely lacking on all sides and in
their intersections. No one�s fault, really, but shameful, all the same,
that through diverse confusions and confabulations, the protection of
the multi-billions that are now spent on not serving well the
information needs of healthcare, end up with money mainly directed,
largely unwittingly, and not in any sense by stupid people, in ways that
have still failed to reach or be allowed near the heart of the matter.
That is where considerations of quality, information and governance
intersect in providing health services that people trust and value. In
such circumstances, there are problems best approached through
simplifying and withdrawing resource; Fred Brooks and his concept of the
mythical man-month is salutary.

openEHR has never yet had external financial support; we, our research
teams, colleagues and parent organisations have done it ourselves. Of
course, it has been largely ignored on high, for as long as possible,
because bottom-up and top-down motivated initiative is bound to
encounter an uncomfortable collision layer in the real world. That
collision is occurring right in the middle of changing patient care. I
have very disappointing records of how the ideas motivating openEHR were
introduced to numerous important people over recent years, illustrating
how weak the critical appraisal of health IT principles still is, in
clinical, management and technical terms.

There seems to be an implication in some of the recent contributions to
the lists that openEHR is somehow now rocking the boat. In terms of its
economic weight, that really feels like criticising someone moving a
deck chair on the Titanic for its demise. Incidentally, according to a
recent paper, it was probably weak rivets and not the iceberg that
caused the disaster. Having just been sailing, forgive me for
introducing a navigational Catch 22. It�s sometimes not a good idea and
in no one�s interest to rock the boat because it may capsize; but you
sometimes have to rock the boat to learn how to build boats safely and
sail them. openEHR and HL7 are contrasting voyages of discovery and
exercises in simultaneous boat, crew and community building, in the open
water. They�re building new kinds of boats and learning how to sail them
at the same time; that needs a certain kind of foolhardy spirit, to be
sure, but innovation was ever thus. In health informatics, there are
some emerging principles about boats, teams, weather and seaworthiness,
but not enough is known yet to be confident about laws covering what is
and isn�t allowed to be a system (boat) and how they should be
regulated; what and where the Plimsoll line might be, for example.

We�re in a situation, nonetheless where many people, who have to get
across the sea, are being persuaded to get into some pretty unseaworthy
boats. That�s an observation about the inner workings of systems and
software, which I�ve observed, for thirty years. It�s not a purist
argument as some pretty ropey early stage software has achieved some
pretty amazing impacts. But it is a comment about mission, method and
maturation of sustainable infrastructure. I could give some old and some
distressingly current examples of unseaworthy systems and projects, but
don�t want to be too provocative.

As the board of directors of the Foundation, we�ve tried always to
keep openEHR itself free from being typecast by things like datatypes,
information models and engineering systems, important though these
undoubtedly are. Let us forget any idea that there are right and wrong
answers to these issues. But let us remember that there are good and bad
approaches and retain an independent sense of what is good enough or not
good enough, in context. Otherwise there will be neither sustained
progress nor proper regulation and governance, and its health care that
will be the worse.

My perspective comes from earlier days as a physicist. Many of the
models that have been at the heart of the evolving discipline of physics
are in some senses both right and wrong. They help in some ways, they
don�t in others. They�re none the worse for that.

A rigorous grip on the scope of the modelled domain and the measurements
and behaviours addressed within it are essential for any modelling
exercise of worth. When I was first studying physics, the vibrational
spectra of nuclei were well predicted by analogy with a spherical drop
of liquid and its vibrations. When you fired protons at a large nucleus
and observed fission and the emission of a whole host of new particles,
you were nowhere near modelling these starting from the analogy of a
spherical drop model. Getting there by further pursuing that analogy and
formula was not a good way forward. The problems of modelling the
nucleus as a many-body problem in quantum mechanics have taken decades
longer than the simple task in classical mechanics of calculating
vibrational properties of a liquid drop. But each model had its domain
and utility. Scientifically, physics didn�t move forward by combining
them into a single omni-domain model, just as the idea of painting a
canvas by mixing all yellows and blues and thus replacing with greens
also loses something. Quantum mechanics and much much more powerful
computers evolved to fulfil the modelling needs of interest and
relevance to contemporary experimental physics.

Since the idea of openEHR first came to us, we�ve tried always to keep
clinical and health care needs and realities at the heart of its
mission, in practical ways. It�s hard to do. What medicine is, how it
works and how one would know what constitutes good medicine are
challenges identified since the times of Florence Nightingale and still
at the heart of practising and managing health care. Innovation can
damage and threaten stability; conservatism and vested interest can
impede useful advance; that�s true everywhere. If you read the biography
of Stanley Prusiner, Nobel Laureate in Medicine for his work on prion
disease, you will see a story of a man blocked at various stages of his
career for his challenge to biological genetics orthodoxy; just as
Copernicus and Galileo challenged the orthodoxies of the church of their
day. Blocked tenure led onto Nobel Prize with stupefying rapidity! All
scientific innovation grows in Conan Doyle�s country of the blind where
the one-eyed man is king. Let�s try and suppress judgmentalism and treat
the journey as an experimental one, guided by implementation experience.
But let us be honest and free in our appraisals, confident that they
will in turn be appraised in a good and fair light.

openEHR as a community has received and has sought noone�s money other
than from those who work directly at its heart. Its rise within the
international agenda is indicative of something. I�m sure we�ll stick at
it, working with everyone, guided by our own perspectives, methods and
ways of doing things. There is a log jam in health IT. A memorable paper
claims that sorting out health care data is an $80billion per annum
problem for the US economy. In some sense, we believe that it needs to
be transformed to a problem perhaps an order of magnitude less than that
in monetary terms. It�s hard to make a business case for saving so much
money when those effectively spending and consuming it are persuaded or
in cahoots that more and more rather than less and less spending of our
societies� money is needed to deal with the problem. Maybe that is
flames from me, now!
