Translational research transforms currently
available knowledge into useful measures for
everyday clinical and public health practice.
Translational research aims to assess
implementation of standards of care,
understand the barriers to their
implementation, and intervene throughout all
levels of health care delivery and public health
to improve quality of care and health outcomes,
including quality of life.

How to select the best study
design
• Study design
– Should be closely linked to the purpose of
the evaluation
– Should build on a theoretical framework of
behavioral change or other relevant strategy
– Should consider randomized designs first
– Non-randomized designs or designs where the
unit of randomization is other than the
participant may be the most appropriate for
implementation research questions
Study design selection
• Challenge in implementation research is
that the interventions are usually
complex (multifaceted with simultaneous
changes in different parts of the
organization)
• Researcher has variable control over how
the intervention is implemented
Eccles M, et al. Qual Saf Health Care 2003;12;47-52
Critical steps in the research plan
before the definitive study
• Development of a theoretical basis for
the intervention
• Define the components of the
intervention
• Exploratory studies of observational data
+ qualitative research to further refine
the intervention and planned evaluation
• Definitive evaluation
Eccles M, et al. Qual Saf Health Care 2003;12;47-52
Types of studies
• Quantitative non-experimental designs
• Quantitative experimental designs
o Randomization
• Qualitative
• Multi-level, multi-factorial interventions
• Community-based participatory research
Quantitative non-experimental
designs
• Cross-sectional designs
• Uncontrolled before and after
(longitudinal observational cohort
studies)
• Controlled before and after
• Time series analyses
• In translational research there can be
political, practical, and ethical barriers
to randomized designs – but randomized
designs should first be considered
Types of intervention studies
• Randomized or quasi-randomized trials
• Interrupted time series (ITS)
– Defined intervention
– 3 points in time before and after
• Non-randomized studies with controls at a
second site
– Data collected before and after the intervention
– Key to interpretation hinges on comparability of
the sites
• Most are evaluations within systems rather
than between systems
Quantitative experimental designs
• Individual patient-level randomized
controlled trials
• Cluster randomized controlled trials
• Strongest designs to establish a causal
relationship
• Often times difficult to implement…
but considering them is important
Randomized controlled trials
• Considered to be the gold standard
– Randomly allocated to either intervention or
control group
– Best way to insure that both known and unknown
factors that may influence effectiveness of the
intervention are balanced in the two comparison
groups
• Time consuming, expensive, complex, may
require a large number of clusters, tight
inclusion criteria limit generalizabilty
• May not tell you whether an intervention
will improve routine practice
Level of randomization
• Patient
• Health care professional
• Practice/hospital
• Provider group
• Health plan
• Community
LOW LEVEL
HIGH LEVEL
CONTAMINATION
POWER, LOGISTICS
Level of randomization
• At higher levels of randomization measurement of pre-intervention characteristics is
critically important
• Consider stratification on baseline
characteristics that are likely to influence
the effectiveness of the intervention
• Cluster randomization is likely to violate the
assumption of independence of observations
within a cluster
– Two patients in same practice are likely to be more
similar than three from different practices
– Need to be able to estimate the intracluster
correlation coefficient (ICC)
Cluster randomization
• Many quality improvement (QI) interventions
are at provider or system level and if you
randomize at individual patient level it is
likely there will be contamination
• Randomization at higher level will reduce
contamination but you pay a high price with
regard to power and ability to detect
clinically meaningful differences in outcomes;
additionally, risk for bias is much higher
• Randomize at a higher level but collect data
at the patient level
Analysis of cluster randomization
• Analysis at cluster level uses the cluster as
unit of randomization and unit of analysis
– Each cluster is treated as one data point
(inefficient!)
• Patient level analyses that are adjusted for
the cluster
• Patient level analyses that allow for
correlation between clusters is explicitly
modeled; hierarchical nature of data is
accounted for in the analysis
• Unit of randomization must be accounted
for in all analyses
Qualitative studies
• Results from qualitative studies can provide
critical information in the translation of
interventions to real world settings that have
been shown to be effective in clinical trials
• Meanings, definitions, and characteristics of
phenomenon
• Increase acceptability, cultural
appropriateness, and feasibility
• Relying on current literature may not be
sufficient
Types of qualitative research
1. Direct observation
– Observe but do not interact
Types of qualitative research
1. Direct observation
2. Written documents
Types of qualitative research
1. Direct observation
2. Written documents
3. In-depth interviews
– Individual interviews
– Focus group discussions
Questions to ask before including
qualitative research in your study
• Is qualitative research the best way to
answer your research question?
• Is the methodology appropriate to the
research question?
– Justify your research method
Mixed Methods Studies
• “Quantitative research excels at
summarizing large amounts of data and
reaching generalizations based on
statistical perceptions. Qualitative
research excels at “telling the story”
from the participant’s viewpoint,
providing the rich descriptive detail that
sets quantitative results into their human
context.”
Trochim, W.M.K., Research Methods Knowledge Base: www.socialresearchmethods.net
Background premises for multilevel, multi-factorial interventions
• We live in contexts: patients, families,
providers, clinics, health systems,
societies
• Behavior change and quality
improvement are difficult
• Multiple interventions are more
effective than single
• Diabetes and obesity are chronic
conditions: chronic care / chronic
disease models
Community-based participatory
research
• Community focus: often vulnerable or
hard to reach populations
• Collaboration: community and academic
partners
• Equal relationships
• Benefit of community
– Ultimately interventions
– Reduce disparities

“comprehensive, applied research that strives
to translate the available knowledge and
make it useful in everyday clinical and public
health practice”
Narayan KM, et al. Ann Int Med 2004; 140: 958-963.
Sustainability

• Who will continue the program after the
research is complete - community members,
the research institution, etc.
• Is the project scalable?
– Future impact
Questions and discussion

minimized
• Lay out study costs and milestones
clearly
Common errors in IDF
applications: pitfalls to avoid

3. Lack of cohesion
4. Readability
2. Not enough detail
•
“no clear view of reach…who will participate and why”

“lack of clear definitions” for outcome measures
•
No description of measurement tools
•
“proposal lacks significant details”
•
No power calculations
•
No support for the feasibility of the study tests and/or
intervention
•
“theoretical framework…is not defined”
3. Disagreement between
different parts of the grant
• “lack of cohesion between” objectives,
study measures, and outcomes
• “timeline and figure” are “somewhat
inconsistent” with the study design
• Costs do not reflect all components of
the study
4. Readability
