Day 1 – Session 2 2
Intervention planning should not begin
until:
the injury problem is well defined and described
you have identified key causal and contextual factors
you know what you are targeting - and why

How do I build
an intervention
plan which is
Strategic and
Effective ?

Day 1 – Session 2 3
What are our options?
Understanding the importance of
selecting:
1. Candidate change targets
Which Prevention Phase are You
Targeting? 1. Pre-Event
Reducing the number of events with the potential to cause injury.
2. Event Reducing the number of injuries
that occur.
3. Post-Event Reducing the severity of injury and
optimizing outcome.

Day 1 – Session 2 6
Dr. Bill Haddon gave us:
10 injury prevention strategies known as
“The Haddon Strategies” (I like to think of these as strategic targets)
The 10 Haddon Strategies Range from “upstream” to downstream approaches
Carolyn J. Cumpsty Fowler, PhD, MPH
July 24-25, 2012
Delaware Injury & Violence Prevention Summit
Day 1 – Session 2 7
Haddon strategies applied - I
#1 Prevent creation of the hazard
ban 3-wheel ATV’s; restrict types of ammunition
#2 Reduce amount of the hazard
limit pills per container; decrease water temperature
#3 Prevent release of the hazard
provide handrails for the elderly; improve brakes
#4 Alter release of the hazard
blister packaging of pills; child restraints
#5 Separate person and hazard in time and space
bike paths; remove trees near roads; evacuate hurricanes
Haddon strategies applied - II
#6 Place barrier between person and the hazard
bike helmets; childproof closures; pool fences
#7 Modify basic qualities of the hazard
breakaway poles; energy-absorbing surfacing
#8 Strengthen resistance to the hazard
physical conditioning; building codes (earthquake)
#9 Detect quickly
smoke detectors; road side phones; early warning systems
#10Repair the damage
EMS; treatment & rehabilitation; self-care training

What are our options?
Understanding the importance of
electing:
1. Candidate change targets
2. Candidate change strategies

• Health Promotion
• Health Behavior Change
• Influencing Social Norms and
Social Will
• Advocacy

Injury Prevention Advocacy
“Injury prevention advocates work to
influence the way the public,
policymakers and other decision
makers think about and act on injury
prevention policies.”

Injury Prevention Approaches
Enforcement
Law
Regulation
Policy
What do these options mean for us?
LAW
GOOD NEWS! The type of intervention we hope to
achieve is not necessarily the type of work we will have
to do to make it happen.
EDUCATION TECHNOLOGY

Day 1 – Session 2 12
Discussion (A.K.A. “Buzz Group”)
1. For each type of strategy, think about
what factors might be important for
that strategy to have the potential to
succeed.
This is about intervention design and
components rather than funding, etc.
2. Can this type of strategy stand alone?
If yes, why?
If no, what could enhance it?
For education & behavior change
strategies to work, the audience must:
Be exposed to the appropriate information
Understand and believe the information
Have the resources and skills to make the
proposed change
Derive benefit (or perceive a benefit)
from the change
Be reinforced to maintain the change over
time Sleet and Gielen, 1998

Day 1 – Session 2 13
Successful implementation of engineering & technology solutions requires that the technology
Be effective and reliable
Be acceptable to the public and
compatible with the environment
Result in products that dominate the
market place
Be easily understood and properly used
by the public
Sleet and Gielen, 1998
Key factors in making legislation and
law enforcement strategies effective
The legislation is widely known and
understood
The public accepts the legislation and its
enforcement provisions
The probability, or perceived probability,
of being caught if one breaks the law is
high
The punishment is perceived to be swift
and severe Sleet and Gielen, 1998

So what should we learn
from this?
Even though many wish it were not so,
single “E” strategies seldom work

Day 1 – Session 2 15
Adopt an Ecological (Multilevel)
Intervention Approach
Single strategies are seldom – if ever – successful
in achieving and sustaining change…
Interventions must be sensitive to the ecological context.
They must address several areas.
To achieve lasting change, interventions must be implemented with enough resource intensity (such as time and engagement).
When intrinsic individual risk factors
exist in the person to be protected
the importance of environmental
change and injury prevention policy
increases.

STAY

!!! Interventions to
prevent injury
may have
unintended
consequences
Anticipate All Consequences
We Must Aim for Action to Achieve Positive Ecological Balance

Environmental conditions favor the agent/vehicle and increase the individual’s risk for illness/injury.
“Negative ecological balance”:
Physical Environment
Agent Social Environment
Environmental conditions favor the individual and reduce the risk for disease/injury.
“Positive ecological balance”:

How do I
choose the
right
approach ?
Different Strategies
Have different strengths and
weaknesses ....
…weigh the pro’s and con’s carefully

When setting priorities, we
consider: Money

From status quo

How do I compare interventions?

The Revised Intervention Decision Matrix ©
Fowler & Dannenberg 1995 (revised 1998, 2003, 2010)
Is a simple tool designed to help people identify
intervention options and choose between them.
It can also help identify long term goals and
intervention options which may support each
other.
Decision criteria used in the
Revised Intervention Decision Matrix ©
Effectiveness
Feasibility
Affordability (Cost-feasibility)
Sustainability
Ethical Acceptability
Social Will
Political Will
Possible Unintended Consequences Benefits
Risks (Avoiding risk = “Potential to do no harm” )

Why do we not use a numeric scoring
system e.g. 1, 2, or 3?
Assembling Our Collective Wisdom
Identify an intervention your group
believes could help prevent the
injury/violence challenge you have
been discussing.
Identify 3 different “candidate”
approaches
Compare them using the RIDM
