The document discusses using theory-based research to improve health informatics (HI). It provides examples of testing theories from fields like communication, decision-making, and behavior change to optimize eHealth interventions before randomized controlled trials. Specific theories and studies testing things like how alert formatting impacts prescribing are summarized. The document argues this approach can help establish HI as a professional discipline by building a scientific evidence base for more reliable eHealth tools.
Clinical Trial Simulation training with simulo 20161124Ruben Faelens
In collaboration with the University of Lyon, we presented a 2-hour session in Clinical Trial Simulation. This session fitted nicely within the Master's program curated by Emilie Henin (Calvagone).
The 10 students managed to explore the PK model for Sunitinib. 4 students struck gold at the end, managing to create an efficient design that proved biosimilarity.

I described these two studies during the Research in Practice: Studies UXers should know about workshop. I expected them to be drive-bys ... as in, "Yah, yah, .. have heard that ... let's move on." I was surprised to find that the group -- a sharp, engaged and thoughtful group-- didn't know these studies. Instead of a few minutes description, we discussed and debated how these studies might influence UX practice for almost an hour. Based on that, I got nudged (Culprit = @susandra Susan Dray) to presenting these two @ the UXPA unconference.

Given the high failure rates and the increased costs of clinical trials, researchers need innovative design strategies to best optimize financial resources and reduce the risk to patients.
Adaptive designs are emerging as a way to reduce risk and cost associated with clinical trials. The FDA recently published guidance (Innovative Cures Act) and are actively encouraging sponsors to use Adaptive trials.
Adaptive design is a clinical trial design that allows adaptations or modifications to aspects of the trial after its initiation without undermining the validity and integrity of the trial.
In this webinar, Ronan will demonstrate nQuery's new Adaptive module focusing on Sample Size Re-Estimation & Group-Sequential Design.

ICU Patient Deterioration Prediction : A Data-Mining Approachcsandit
A huge amount of medical data is generated every da
y, which presents a challenge in analysing
these data. The obvious solution to this challenge
is to reduce the amount of data without
information loss. Dimension reduction is considered
the most popular approach for reducing
data size and also to reduce noise and redundancies
in data. In this paper, we investigate the
effect of feature selection in improving the predic
tion of patient deterioration in ICUs. We
consider lab tests as features. Thus, choosing a su
bset of features would mean choosing the
most important lab tests to perform. If the number
of tests can be reduced by identifying the
most important tests, then we could also identify t
he redundant tests. By omitting the redundant
tests, observation time could be reduced and early
treatment could be provided to avoid the risk.
Additionally, unnecessary monetary cost would be av
oided. Our approach uses state-of-the-art
feature selection for predicting ICU patient deteri
oration using the medical lab results. We
apply our technique on the publicly available MIMIC
-II database and show the effectiveness of
the feature selection. We also provide a detailed a
nalysis of the best features identified by our
approach.

Opening Keynote "Research in an IT Connected World: Building Better Partnerships – NIH and Health Care Systems"
The era of ‘Big Data’ has arrived for biomedical research, bringing with it immense challenges as well as spectacular opportunities. NIH is establishing major programs with the potential to transform the future of US biomedical research by building the capacities necessary for these challenges. These programs will strengthen research partnerships with health care systems and the IT networks that support them.
The Big Data to Knowledge (BD2K) initiative, to be launched in 2014, will implement a set of recommendations from the Data and Informatics Working Group to the Advisory Committee to the Director. Investments are planned to meet scientific needs to manage and utilize large complex datasets, including strengthening training, and investing in improved analysis methods and software development and dissemination. NIH is also evaluating strengthening data and software sharing policies, and the potential creation of catalogs of research data, and data/metadata standards.
The Common Fund’s Health Care Systems (HCS) Research Collaboratory program has the goal to strengthen the national capacity to implement cost-effective large-scale research studies by engaging major health care delivery organizations as research partners. The aim of the program is to provide a framework of implementation methods and best practices that will enable the participation of many health care systems in clinical research. Research conducted in partnership with health care systems is essential to strengthen the relevance of research results to health practice. Seven demonstration projects, currently in a feasibility phase, are developing detailed methods to implement rigorous randomized studies of questions of major public health impact. These studies, and the IT infrastructure that will make them possible, will be described in detail.
Big data, RWE and AI in Clinical Trials made simpleHadas Jacoby
Technology is slowly but surely penetrating the healthcare industry in general and the clinical trials sector in particular. New and advanced solutions offer a variety of possibilities aimed to both improving existing processes and creating new and more efficient ones. And on top of all stands the desire to make clinical trials more patient centric.
In all of this, even though some of the technologies have yet to mature enough to meet the high quality standards necessary, it is important to know them and begin imagining the promise they hold for clinical trials.

The quantified self: Does personalised monitoring change everything?
1115 wyatt wheres the science in hi for christchurch nz oct 2015
1. How can research reveal the science underlying
health informatics ?
So we can make HI more professional - like building bridges
Prof Jeremy Wyatt DM FRCP ACMI Fellow
Leadership chair in eHealth research, University of Leeds, UK
Clinical adviser on new technologies, Royal College of Physicians
From 1/1/16: Director, Wessex Institute of Health, University of
Southampton
j.c.wyatt@leeds.ac.uk
2. Some tough questions
1. Why are usable EPRs so hard to engineer ?
2. Why do one third of CDSS trials fail (Garg 2005) – when
those CDSS must be very well engineered for an RCT ?
3. How can an ePrescribing system cause so much harm ?
(Koppel, JAMA 2005)
A clue: why don’t bridges fall down nowadays:
a) There is a science of materials and construction methods
b) Engineers are professionals: they learn the science &
keep up to date
Tay Bridge disaster, 1879
3. Is HI / eHealth a “professional”
discipline yet ?
Evolution of professionalism:
• Intuition – a craft
• Mapping, taxonomy – a trade
• Testing of predictive theories - research
• Reliable engineering based on this – a profession
Heathfield H, Wyatt JC. Methods Inf Med, 1995
For HI:
1960-70s
1980-1990s
2000-2020
2020 on ?
4. What kinds of theories are relevant
in eH / HI ?
User 2
Health information
system
Decision
Improved behaviour
& outcome
User 1
Theories of communication
Theories of information retrieval
Theories of decision making
Behaviour change theories
(personal / organisational)
Consider a simple eHealth system: an internet forum to support
smoking cessation
5. How to carry out theory-based
eHealth research
Identify a promising theory
Identify a common, important
eHealth problem
Version of information system
that ignores the theory
Incorporate this theory
into an information system
Measure
usage & impact
of both systems
Analyse problem characteristics
and possible solutions
New knowledge about the
problem - and the theory
Literature review,
systematic review

7. Example 2: does feedback on group
performance increase exercise ?
RCT with 32 students: all sent us daily txt msg of step count
Half (“Team B”) got weekly feedback on total step count of
“their” group vs control group
Modest support for “group obligation” theory
Control (team A)
Intervention (team B)
Work of Sam Dhesi,
Medical Student, Leeds
8. Intervention modelling
experiments
Aim: to optimise the intervention before an RCT
Example methods:
• Attitude surveys
• Focus groups
• Formal usability studies
• Log file analysis
• Eye tracking studies
• Neuromarketing methods
• Simulated decision studies
9. Example 3: How to improve the
acceptability of prescribing alerts?
DSS are effective tools to improve prescribing (Garg
2005)
However, GPs usually turn off their prescribing alerts,
because:
• Too many alerts – no grading by severity
• False positives: poor knowledge base, poorly coded data
Question:
• Can we improve acceptability of alerts while still
reducing prescribing errors ?
Work of Greg Scott, ACF, London funded by NPfIT
10. Potential ways to improve
clinical alerts
Alert content:
• Wording – signal words (“Warning !”)
• Other material: symbols – alert triangles etc.
• Clickable list of actions to perform
Alert accuracy:
• Improve completeness, quality of coded patient data
• Improve completeness, quality of drug knowledge
• Improve underlying alert logic eg. calculate event probability
How the alert appears on screen:
• Location, size
• Persistence
13. Summary of results
Modal alerts: participants 12X (95% CI 6.0 to 22.3) less likely to make prescribing
error than when not shown any alert
Non-modal alert: 3 times (CI 1.9 to 5.3) less likely to make prescribing error
Non-modal alert error rate 4 times higher (CI 1.9 to 7.0) than with modal alerts
“Safe” Dr = 0 or 1 error out of 24 scenarios
14. Some participant comments
“When you are in a rush, the one that pops up is better –
forces you to click on OK”
“Pop-ups make you think more as you do it”
“[I prefer] interruptive – likely to miss otherwise. But
recognise the problems, irritating in daily use.”
“Interruptive tend to be annoying. But if it’s something you
don’t want to miss…”
“Difficult to say what deserves one type or other of alert”
“Didn’t notice it”
Published as: Scott et al JAMIA 2011
15. The MOST SMART approach
MOST: multiphase optimisation (of complex
interventions):
1. Screen intervention components for effectiveness (lab expts
on simulated decisions, RCTs, full / fractional ANOVA…)
2. Fine tune the combination of intervention components using
SMART, qv.
3. Standard RCT to confirm effectiveness
SMART: sequential multiple assignment randomised
trial (of time-varying interventions):
• Randomise participants at each stage to competing
interventions, as suggested by theory
• Collins et al. Am J rev Med 2007
16. SMART: example for an

17. What is eHealth research
really for ?

problem
18. Benefits of building the
eHealth “theory base”
• No more trial and error or re-invention of ad hoc systems
that seemed sensible at the time
• eHealth will evolve from an intuitive craft (reliant on
experts and apprenticeship) into a professional discipline,
making its decisions based on tested theories
• Systems will be safe, efficient & predictable (like bridges)
• No need to evaluate every version of every app / website
/ serious game...
19. Conclusions
1. Professionalism requires sound theories
2. eHealth research should test theories from
information, cognitive, organisational and
computer science
3. Suggested procedure:
• Define a question of generic importance to our field
• Identify a candidate theory, relevant eHealth case
study & potential biases
• Select the best evaluation method to test the theory
• Carry out the study
4. Promote the results to students and eH
practitioners

delivered as planned.
25. Neuromarketing – a food industry
example
Theory: for behaviour, emotion > information (Kahneman’s System 1)
Methods: FMRI; EDA; facial EMG; web-cam facial expression recognition
26. Study aim & methods
Aim: to help develop more effective SMS msgs for health
promotion, by:
• Developing a reliable methods to capture EDA, facial EMG
• Validate it against words & phrases of known emotional import
• Use it to test & improve new phrases and txt msgs before an RCT
Methods - 40 volunteers:
• Measure EDA and facial EMG
• Exposed to 20 words of known emotional import, 5 words about
exercise, 5 nonsense words & their own name in random order
Work of Gabriel Mata, Leeds PhD student funded by CONACYT, Mexico
Example of a non-interruptive alert for the same error
In HC we sometimes abuse technology, with serious consequences
Technologists sometimes misunderstand our problems – Japanese art of Chindogu
Sometimes it feels like doctors & technologists inhabit 2 worlds - Maurits Escher – one neat & tidy, the other a bit more real… and I often seem to be the bridge between the two
Gabriel Mata’s research project will explore the role of SMS and related communication tools to address obesity in less developed countries. Supported by Mexican govt. National Council for Science & Technology
In 2010 OECD declared Mexico as the worst affected country, with 30% of population obese and 70% overweight.
