“Science can identify solutions to pressing public health problems, but only politics can turn most of those solutions
into reality.”
Thomas Oliver, PhDJohns Hopkins Bloomberg School of Public Health

Objectives
1. Understand the definition of evidence-based policy
2. Understand some important barriers and challenges
3. Explore how to overcome some of these barriers4. Illustrate principles with recent research results

What is a health policy?
![Page 5: Using Evidence Based Public Health Policy to Prevent and Control Cancer](https://reader036.fdocuments.in/reader036/viewer/2022062614/5469d768af7959cb768b62db/html5/thumbnails/5.jpg)
Definitions
• “those laws, regulations, formal and informal rules and understandings that are adopted on a collective basis to guide individual and collective behavior”– Policies tend to influence the environment (legal,
social, economic, and physical)– Importance noted in the definitions of core
functions of public health
![Page 6: Using Evidence Based Public Health Policy to Prevent and Control Cancer](https://reader036.fdocuments.in/reader036/viewer/2022062614/5469d768af7959cb768b62db/html5/thumbnails/6.jpg)
At least 3 types of policy
• Formal laws, codes, regulations– Clean indoor air policy
• Written standards that guide choices– Engineering standards that guide street design
• Unwritten social norms– Not ticketing for speeding 6-7 MPH above limit– Harder to evaluate, often culturally driven
![Page 7: Using Evidence Based Public Health Policy to Prevent and Control Cancer](https://reader036.fdocuments.in/reader036/viewer/2022062614/5469d768af7959cb768b62db/html5/thumbnails/7.jpg)
How has health (or other) policy, today, already affected your life?
Policy potential

Top 10 public health achievements
• Examples– Vaccination– Motor-vehicle safety– Safer workplaces– Fluoridation of drinking water– Recognition of tobacco use as a health hazard
• Each of these advances involved policyCenters for Disease Control and Prevention. Ten great public health achievements--United States, 1900-1999. MMWR 1999 Apr 2;48(12):241-3

Understanding evidence-based approaches
![Page 10: Using Evidence Based Public Health Policy to Prevent and Control Cancer](https://reader036.fdocuments.in/reader036/viewer/2022062614/5469d768af7959cb768b62db/html5/thumbnails/10.jpg)
A simple definition of evidence-based public health
“Evidence-based public health is the process of integrating science-based interventions with community preferences to improve the health of populations.”
Kohatsu, et al. Am J Prev Med 2004.
![Page 11: Using Evidence Based Public Health Policy to Prevent and Control Cancer](https://reader036.fdocuments.in/reader036/viewer/2022062614/5469d768af7959cb768b62db/html5/thumbnails/11.jpg)
Elements of evidence-based policy
• Process
• Content
• Outcomes
![Page 12: Using Evidence Based Public Health Policy to Prevent and Control Cancer](https://reader036.fdocuments.in/reader036/viewer/2022062614/5469d768af7959cb768b62db/html5/thumbnails/12.jpg)
Domains of Evidence-based Public Health Policy
Domain Objective Data Sources
Process To understand approaches to enhance the likelihood ofpolicy adoption
• Key informant interviews • Case studies
Content To identify specific policyelements that are likelyto be effective
• Systematic reviews • Content analyses
Outcome To document the potentialimpact of policy
• Surveillance systems • Natural experiments tracking policy-related endpoints
![Page 13: Using Evidence Based Public Health Policy to Prevent and Control Cancer](https://reader036.fdocuments.in/reader036/viewer/2022062614/5469d768af7959cb768b62db/html5/thumbnails/13.jpg)
Why worry about research & policy/practice?
“… as the pressure on resources increases, decisions will have to be made explicitly and publicly, those who make decisions will need to be able to produce and describe the evidence on which each decision is based.” (Gray, 1997)
![Page 14: Using Evidence Based Public Health Policy to Prevent and Control Cancer](https://reader036.fdocuments.in/reader036/viewer/2022062614/5469d768af7959cb768b62db/html5/thumbnails/14.jpg)
What do policymakers want or need from practitioners and
researchers?
![Page 15: Using Evidence Based Public Health Policy to Prevent and Control Cancer](https://reader036.fdocuments.in/reader036/viewer/2022062614/5469d768af7959cb768b62db/html5/thumbnails/15.jpg)
Three Fundamental Questions
1. Is there a problem?2. Do we know how to fix it (intervention)?3. How much will it cost (financially, politically)?
- What do all of these questions mean in the context of where we live and work?
![Page 16: Using Evidence Based Public Health Policy to Prevent and Control Cancer](https://reader036.fdocuments.in/reader036/viewer/2022062614/5469d768af7959cb768b62db/html5/thumbnails/16.jpg)
Challenges and opportunities for evidence-based policy
Finding the research-policy nexus
![Page 17: Using Evidence Based Public Health Policy to Prevent and Control Cancer](https://reader036.fdocuments.in/reader036/viewer/2022062614/5469d768af7959cb768b62db/html5/thumbnails/17.jpg)
Where am I?
You’re 30 yards above the
ground in a balloon
You must be a researcher
Yes. How did you know?
Because what you told me is
absolutely correct but completely
useless
You must be a policy maker
Yes, how did you know? Because you don’t
know where you are, you don’t know where you’re going, and now
you’re blaming meThe problem
![Page 18: Using Evidence Based Public Health Policy to Prevent and Control Cancer](https://reader036.fdocuments.in/reader036/viewer/2022062614/5469d768af7959cb768b62db/html5/thumbnails/18.jpg)
What are we learning about translating evidence to policy?
![Page 19: Using Evidence Based Public Health Policy to Prevent and Control Cancer](https://reader036.fdocuments.in/reader036/viewer/2022062614/5469d768af7959cb768b62db/html5/thumbnails/19.jpg)
Examples of Policy Translation Challenges
1. Clash of cultures
2. Poor timing
3. Ambiguous findings
4. Balancing objectivity and advocacy
5. Lack of relevant data
From Brownson et al. AJPM 2006

Qualitative interviews with health committee members
![Page 36: Using Evidence Based Public Health Policy to Prevent and Control Cancer](https://reader036.fdocuments.in/reader036/viewer/2022062614/5469d768af7959cb768b62db/html5/thumbnails/36.jpg)
When you hear the term “scientific evidence” what does that mean to you?
• “Not much. The term is thrown around a lot. Science doesn’t mean it is good science.”
• “I like to see things that are evidence-based and peer-reviewed.”
• “Scientific is the opposite of anecdotal evidence, so anecdotal evidence is what we rely on …to make our decisions, unfortunately.”
![Page 37: Using Evidence Based Public Health Policy to Prevent and Control Cancer](https://reader036.fdocuments.in/reader036/viewer/2022062614/5469d768af7959cb768b62db/html5/thumbnails/37.jpg)
Where do you go for scientific information?
• “My most trusted source…I have a lot of constituents who bring items to me or ask me about things and I collect data from them…”
• “We get info from the various entities and the lobbyists as well as the other organizations that are in support or against a particular issue.”
• “We always check the internet first…”
• “Well I have not…I don’t think I’ve ever thought I needed scientific evidence…”
![Page 38: Using Evidence Based Public Health Policy to Prevent and Control Cancer](https://reader036.fdocuments.in/reader036/viewer/2022062614/5469d768af7959cb768b62db/html5/thumbnails/38.jpg)
What can you do to bridge the chasm between evidence and policy?
![Page 39: Using Evidence Based Public Health Policy to Prevent and Control Cancer](https://reader036.fdocuments.in/reader036/viewer/2022062614/5469d768af7959cb768b62db/html5/thumbnails/39.jpg)
1. Understand the process2. Find a way to be involved in the process3. Communicate information more effectively4. Utilize analytic tools5. Educate a range of “players” (staffers, advocates)6. Provide training and education programs
What can you do to bridge the chasm between evidence and policy?
![Page 40: Using Evidence Based Public Health Policy to Prevent and Control Cancer](https://reader036.fdocuments.in/reader036/viewer/2022062614/5469d768af7959cb768b62db/html5/thumbnails/40.jpg)
• Vast literature in social psychology suggests policymakers mainly rely on– Habit, stereotypes, cultural norms– Sender credibility
• Factors affecting receptivity of policymakers to info-bearers– Transparency of methods – Plausibility of analysis – Experts’ credentials – Perceived impartiality – Perceived track record – Perceived honesty
Understand the process
![Page 41: Using Evidence Based Public Health Policy to Prevent and Control Cancer](https://reader036.fdocuments.in/reader036/viewer/2022062614/5469d768af7959cb768b62db/html5/thumbnails/41.jpg)
Understand the process
Political context • policy-making less a rational act than a process of social influence• “policy windows open infrequently and do not stay open long”
(Kingdon, 1995)• important to understand which policy options have the greatest
potential for adoption and when small incremental changes are the preferred option
• use of rhetoric, art of persuasion, and ability to relate to the media (so called media or policy advocacy)
![Page 42: Using Evidence Based Public Health Policy to Prevent and Control Cancer](https://reader036.fdocuments.in/reader036/viewer/2022062614/5469d768af7959cb768b62db/html5/thumbnails/42.jpg)
Be involved in the process
Five key areas predict health policy capacity in public health practice:
1) a well-organized agency including an effective organizational structure and central liaison responsibilities
2) talented staff3) clear communications between the public health agency and
policymakers4) effective negotiation skills5) active participation
![Page 43: Using Evidence Based Public Health Policy to Prevent and Control Cancer](https://reader036.fdocuments.in/reader036/viewer/2022062614/5469d768af7959cb768b62db/html5/thumbnails/43.jpg)
• Consider a continuum of advocacy– Raise general awareness
• Publish an article• Present at a professional meeting
– Communicate findings to policymakers• Develop short policy summaries• Make data understandable to policymakers
– Actively lobby for a particular issue• Conduct media advocacy
Be involved in the process
![Page 44: Using Evidence Based Public Health Policy to Prevent and Control Cancer](https://reader036.fdocuments.in/reader036/viewer/2022062614/5469d768af7959cb768b62db/html5/thumbnails/44.jpg)
• “All politics is local.” – The policy choices of elected officials are often designed to support
their interest in being re-elected or re-appointed– Agenda often don’t drive re-election, rather political parties
• Calculate statistics at the voting district or even precinct level than at the city level– Make personal contact
• Break material down into bulleted or otherwise highlighted text (policy briefs)– Use charts or graphs illustrating key points– Explore the use of storytelling
Communicate information more effectively
![Page 45: Using Evidence Based Public Health Policy to Prevent and Control Cancer](https://reader036.fdocuments.in/reader036/viewer/2022062614/5469d768af7959cb768b62db/html5/thumbnails/45.jpg)
• Systematic reviews (like the Community Guide: www.thecommunityguide.org)• Cost data• Cost-effectiveness data• Health impact assessments
Better utilize analytic tools (resources)
![Page 46: Using Evidence Based Public Health Policy to Prevent and Control Cancer](https://reader036.fdocuments.in/reader036/viewer/2022062614/5469d768af7959cb768b62db/html5/thumbnails/46.jpg)
• For example, legislative staff members– Gatekeepers and opinion shapers– Often have a great deal of influence in forming the
priorities of an elected official
• Build their knowledge and understanding of evidence-based approaches to policymaking– Legislative staff seem to prefer longer, detailed reports– Elected officials prefer short summaries
• Educate and engage the media
Educate/advocate with a range of “players”
![Page 47: Using Evidence Based Public Health Policy to Prevent and Control Cancer](https://reader036.fdocuments.in/reader036/viewer/2022062614/5469d768af7959cb768b62db/html5/thumbnails/47.jpg)
• Most public health training programs focus on more analytic methods– Yet lack more applied skills
• Look for models– Many advocacy groups sponsor meeting and trainings to
demonstrate the value of academic, industry, and government research
• Informal approaches may be even more effective– One on one meetings– What works in your own setting?
Provide training and education programs
![Page 48: Using Evidence Based Public Health Policy to Prevent and Control Cancer](https://reader036.fdocuments.in/reader036/viewer/2022062614/5469d768af7959cb768b62db/html5/thumbnails/48.jpg)
Overall Summary
Health policy development is crucial to health yet not always rationale and timely
To make progress it is important to understand barriers and all three domains of EB policy
Try to understand what is reasonable and potentially effective in your local situation
Find a way to be an advocate!

How do your experiences with policymakers compare with ours and our findings?
How do the various levels at which policy is made (local, state, federal) impact your involvement with the policy process?
