Why have behavioural approaches to Knowledge Transfer? Martin Eccles Professor of Clinical Effectiveness

Why have behavioural approaches to
Knowledge Transfer?
Martin Eccles
Professor of Clinical Effectiveness
What I’m going to talk about
• Why think about behavioural approaches?
• What we know about KT interventions and the
problems with this
• Theory in behavioural approaches
• All patients should receive appropriate care
Why think about behavioural
approaches?
•
Human behaviour is a major determinant of health
– Health related behaviours of patients
– Health service providing behaviours of HCPs
•
Interventions can change behaviour
– Patients
• Behavioural versus pharma
– KT
• Behavioural
•
But there is much we don’t know
•
So … here’s a story to illustrate where we are in KT
– With thanks to Kaveh Shojania & Jeremy Grimshaw
A fairy story?
•
•
•
Replace “patients” with “KT problems”
– the state of the science for promoting the translation of
evidence from clinical research into practice.
From the perspectives of clinical medicine and the research
enterprise
– Absurd to proceed directly from a patient’s poorly
understood complaints to reaching for a bottle of pills simply
because they are handy and resemble ones recommended
anecdotally by a colleague.
– The decision to administer these pills without any
understanding of their active ingredients or their mode of
action would be completely unsupportable
Yet comparably unsupportable activities occur routinely in KT
research
What do we know?
• Grimshaw JM, et al. Effectiveness and efficiency of
guideline dissemination and implementation
strategies. Health Technol Assess 2004.
– 285 reports of 235 studies, 309 comparisons
• Wensing, et al. Organizational interventions to
implement improvements in patient care: a structured
review of reviews. Implementation Science 2006.
– “Planned re-arrangements of one or more aspects of the
organization of patient care”
– 36 reviews; 684 studies
Results
• Improvements in direction of effect in 86% of
comparisons
– Reminders most consistently observed to be
effective
– Educational outreach only led to modest effects
– Dissemination of educational materials may lead
to modest but potentially important effects (similar
effects to more intensive interventions)
– Multifaceted interventions not necessarily more
effective than single interventions
Results
•

•
•
•
•
Revision of professional roles: 9 reviews
• Can improve professional performance; preventive care
Multidisciplinary teams: 5 reviews
• Can improve patient outcomes; chronic diseases
Integrated care services: 8 reviews
• Can improve patient outcomes and save costs; chronic
conditions
Knowledge management: 6 reviews
• Professional performance and patient outcomes can be
improved; across conditions
Quality management: 2 reviews
• Effects remain uncertain
Mixed interventions: 7 reviews
• 6 showed positive effects
So … what do we know?
•
Most things work some of the time
– There are limitations
• Methodological quality poor
• Little economics (29%) or theory (27%)
– Results likely to be confounded
• Researchers didn’t randomly choose interventions
• Differences in context etc.
– Direct application of reviews problematic
Foy R, et al. What do we know about how to do audit and
feedback? Pitfalls in applying evidence from a systematic
review. BMC Health Services Research 2005, 5:50.
And … what do we need to know?
• What is the efficiency of interventions?
– How interventions work
– Why interventions work
– Can interventions be replicated
• How generalisable are effects?
Which means what, exactly?
Which means what, exactly?
• Generalisable frameworks
– Empirical
– Theoretical
• Better studies (for another presentation)
– Ask and answer smarter questions
• Levels of engagement
• Improved designs
• Process evaluations
Theories or models?
•
Classical theories/models of change can be informative and
helpful for identifying the determinants of change
• Provide organization for thinking, for observation, and for
interpreting what is seen.
• They provide a systematic structure and a rationale for
activities
– Interventions are more likely to be effective if they target
causal determinants – these are theoretical constructs
• Models reflect the philosophical stance, cognitive orientation,
research tradition, and practice modalities of a particular group
of scholars.
• Researchers, policy makers, and change agents tend to be
more interested in planned change theories/models that are
specifically intended to be used to guide or cause change
Using theories
• Does theory apply to clinicians?
– Are doctors human beings?
• What do you want theory to do?
• Describe or predict?
• What level are you working at?
Do theories of human behaviour
(TPB) apply to clinicians?
• Non-clinicians
– Meta-analysis of 10 meta-analyses (Sheeran)
• Intention accounted for 28% of the variance in behaviour
– 185 independent studies (Armitage and Connor)
• TPB (intention and perceived behavioural control)
accounted for 27% of the variance in intention
– 31% if behaviour measures were self-reports
– 20% if behaviour measures were objective or observed
– Meta-analysis of 47 experimental tests of the
intention-behaviour relationship (Webb &
Sheeran)
• A “medium-to-large” change in intention leads to a
“small-to-medium” change in behaviour
Do theories of human behaviour
(TPB) apply to clinicians?
• Clinicians
– Systematic review of 10 studies included a total of
1623 subjects (Eccles et al)
• proportion of variance in behaviour explained
by intention was of a similar magnitude to that
found in non-health professionals
• More consistently the case for studies in which
intention-behaviour correspondence was good
and behaviour was self-reported
Choosing theories
• Theories of “behaviour” or of “behaviour
change”?
– Focus on theories that:
• Have been empirically tested
• Explain behavior in terms of factors that
are amenable to change
• Include non volitional factors
Michie et al. Making psychological theory useful for
implementing evidence based practice: a consensus
approach. QSHC 2005; 14: 26-33.

Choosing theories: Levels
• Four levels at which interventions to improve the
quality of health care might operate:
– Individual health professional
– Health care groups or teams
– Organisations providing health care (e.g., Acute
hospitals)
– The larger health care system or environment in
which individual organizations are embedded
Ferlie EB, Shortell SM. The Milbank Quarterly
2001
Choosing theories: Levels
• Different theories will be relevant to interventions at
different levels
– Health Psychological theories may be more relevant to
interventions directed at individuals and teams
– Theories of organisational change may be more relevant to
interventions directed at teams or hospitals
• Little experience of “mix n match” across levels
Conclusions
• KT is a uniquely “behavioural arena”
• Theory has the potential to lead to greater
understanding
• Theory potentially addresses generalisability
• Which theory/theories to choose?
– Theories of “what”?
– “Behaviour” or “Behaviour change”?
• Many unresolved methodological challenges in
operationalising theory
