Example L.E.A.D. Framework Evidence Report

  1. Question Asked by the Decision Maker

    State the problem posed by the decision maker. For example:

    This summary was prepared to inform the School Board [decision maker] concerning the issue of whether soda vending machines should be removed from high schools to contribute to the prevention of obesity among our students.

  2. Strategy for Locating Evidence

    Summarize the strategy for locating evidence. For example:

    1. To determine the current childhood obesity situation in our city, we accessed data available from the Department of Health and from the public schools.

    2. We asked Dr. Smart from the Public Health School to perform a search using multiple databases, including MEDLINE, the Cochrane Database of Systematic Reviews, and SCOPUS, to determine the available evidence linking soda machines to childhood obesity. Relevant articles were retrieved according to the L.E.A.D. framework methods.

    3. Community leaders (Superintendent of Schools, School Council Chair, and Commissioner of the Department of Health) were asked to review the evidence table and comment on its accuracy and completeness.

This list may include much more evidence from many sources—these are just examples.

  1. Evidence Table

    Develop a table summarizing the characteristics of the evidence that was gathered, including its quality. The evidence should be organized by the “Why,” “What,” “How” typology of the L.E.A.D. framework and its quality assessed according to the methods described in Chapters 5 and 6. See a brief example of an evidence table in Table 7-2.

  2. Summary of Evidence

    Synthesize the evidence according to L.E.A.D. framework considerations and methods described in Chapter 7, and summarize it according to the “Why,” “What,” “How” typology. For example:

    1. Why should we do something about this problem in our situation? Data from our Department of Health indicate that rates of obesity in our high school students are among the highest in the state, and current trends demonstrate the problem is getting worse.

Strategy for Locating Evidence

As described in detail in Chapter 5, the strategy for locating evidence should begin with answering the three questions that frame the discussion in this chapter: (1) Why should we do something about this problem in our situation? (2) What specifically should we do about this problem? and (3) How do we implement this information for our situation? Collecting evidence in accordance with this typology will help expand the perspective on the forms of evidence that are potentially relevant to answering the obesity prevention question asked by the decision maker and on the potential sources from which to gather that evidence. The strategy used to locate evidence for each potential intervention depends on the context of the question being asked, as well as
