Session Objectives

• Know where to:• Find evidence-based approaches (programs,

policies, & strategies)• Look for additional resources to assist in

planning and implementing an intervention

• Apply criteria to evaluate sources of evidence-based approaches

Activity: Using the Community Guide and RTIPs

Sources of Evidence Based Approaches

Key criteria for selecting which sources of evidence to use

• What types of evidence and other information are they disseminating?

• Who created the resource? Do they have profit or ideological motives that might bias their presentation of evidence?

• How current is the information?

• What are their methods for reviewing the literature or reviewing intervention programs?

• What criteria do they use to rate their evidence?

What Works for Health evidence rating criteria

• Scientifically Supported: It works -- numerous studies or systematic review(s) with strong positive results; no substantial contradictory evidence.

• Some Evidence: It has been shown to work more than once -- research suggests positive impacts overall...

• Expert Opinion: Recommended by credible groups; research evidence limited…

• Insufficient Evidence: • Mixed Evidence: • Evidence of Ineffectiveness:

Packaged policy interventions from research and practice from Center TRT

Research-tested interventions – interventions for which efficacy/effectiveness has been tested in one or more research studies...

Practice-tested interventions – practitioner-developed interventions that show promise based on their underlying theory, use of evidence-based strategies, and potential for public health impact (RE-AIM) based on evaluation findings…

Emerging interventions - practitioner-developed interventions that show promise, but lack evaluation data.

Center TRT Disseminates Three Types of Intervention Programs

Example of Practice-Tested

North Carolina Prevention Partners’ Pricing Initiative

• Hospitals increased availability & visibility of healthy foods and beverages

• Decreased prices of healthy items/increased prices of less healthy items in cafeterias

• In one hospital, pre-post data showed positive change in purchasing

Take-home points

• There are no agreed upon criteria for assessing an evidence-based intervention. Organizations vary on criteria used.

• There are numerous sources of evidence-based interventions, but it’s buyer beware!

Group Activity – Looking for an EBA 1. Pull out Sources of Intervention Strategies and Programs from folder2. Identify a source with EBIs to address you prioritized problem.3. Ask yourself the following:

• Is the site disseminating recommendations or

packaged programs?• Who created the site? Are they credible and relatively

unbiased?• Is the information on the website current?

Can you tell when it was last updated?• What methods are they using to review evidence?• What criteria they using to rate the evidence?

40

But what do I do when there are no evidence-based strategies or packaged programs that match my practice problem?

Search the Literature for Relevant Research

• What does the research evidence suggest are the best strategies for addressing the problem in populations and settings similar to ours?
