PhD Thesis At UCL CHIME –University College, University of London –Centre for Health Informatics and Multi-professional Education –Supervisor: Prof. Dipak Kalra (editor of CEN 13606) © Blue Wave Informatics LLP, 2010

© Blue Wave Informatics LLP, 2011 Why am I doing this (thesis)??? This is a crowded area – there are lots of specifications describing a person’s medication information –In the UK – RFA, PSIS, LRA –In the US – CCR/CD –In Europe, CEN –HL7 – Clinical statement, Medication Query –Now also – IHE? The value of a medication profile is well known, well recognised and well understood BUT: There is still no single well accepted “standard” anywhere, that stands up to rigorous evaluation

© Blue Wave Informatics LLP, 2011 So, my aim: (I) To write a thesis describing a comprehensive medication profile –That is “evidence-based” – or at least reasonably logic based –Not design by “hobby-horses”, or by who shouts loudest –That looks from all perspectives, encompassing all stakeholders –Patient and practitioner –Provider and researcher –That is practical –Technically implementable –Clinically useful »Good value for effort

© Blue Wave Informatics LLP, 2011 What am I doing? (I) Gathering requirements from all (!) perspectives –Clinical care –Drug discovery and development –Public health and (pharmaco)epidemiology Listing and discussing sources of information –Prescribing records –Dispensing records –“Medication statements” –OTC information –Others

What am I doing? (II) Discussing the “general considerations” –Scope of “medicines! –Terminology/identification of medicines –Information governance (not security) –Negation statements Build an information model (static requirements) –With robust definitions and examples Build a process model (dynamic requirements) –Again, with robust definitions and examples Test it! © Blue Wave Informatics LLP, 2010

© Blue Wave Informatics LLP, 2011 How am I going to test it? My current thinking is.... For the static model part: –Use patient interviews to populate the model (across the spectra – clinical and research) –Compare that population to what is present in existing systems –Are there any issues, benefits etc.? If so, what might their significance be? For the dynamic model part: –Highlight any differences in current practice –Use questionnaire (and possibly wireframes) to try to access the impact and benefit/cost of these differences What about the “unsung” areas – vaccines, contrast media etc.?

© Blue Wave Informatics LLP, 2011 Where have I got to? Not very far.  Some of the “general” chapters have been written Some of the requirements gathering is done, but not all –A lot from my own professional background Can do this fine – maybe I should do this more (!) –But need to find (or otherwise) evidence Literature searching – not my most inspiring activity! Not yet made any attempt to draw a model (although have tons of ideas and much past experience to draw on) –I plan to start soon, as modelling is always an iterative process
