Brownson et al (2009) And the Definition of Evidence-Based Policy

The objective of this study is to examine how Brownson et al. (2009) defines evidence-based policy and to discuss the three domains of evidence. Additionally this work will consider that recently a number of agencies adopted a public health policy supporting legislation to ban the use of artificial Trans fats in restaurants and bakeries nationwide and will discuss the evidence basis for the policy. The approach of Brownson et al. will be applied in examining the three domains and in determining the evidence basis for the policy.

Brownson et al. (2009)

The work of Brownson, et al. (2009) states that public health policy has an important effect on the individual's health status and that what is missing from the knowledge available is "a clear articulation of the definition of evidence-based policy and approaches to move the field forward." (p. 1576) The three key domains of evidenced-based policy are reported by Brownson et al. (2009) to include: (1) process to understand approaches to enhance the likelihood of policy adoption; (2) content, to identify specific policy elements that are likely to be effective; and (3) outcomes, to document the potential impact of policy. (p. 1576)

II. The First Domain

The first domain or that of the "process" domain has the objective of understanding approaches that will enhance the likelihood of adoption of policy. The data sources of this first 'process' is reported to be "key informant interviews, case studies, and surveys of setting specific-political contexts." (Brownson, et al., 2009, p. 1578) The example stated by Brownson et al. (2009) is related to "…understanding the lessons learned from different approaches and key players, included in state health reforms.

III. The Second Domain

The second domain or that of 'content' has the stated objective of the identification of "specific policy elements that are likely to be effective." (Brownson, et al., 2009, p. 1578) Data sources in this second domain are reported to include systematic reviews and content analyses. (Brownson, et al., 2009, p. 1578) It is reported that an example is the development of "model laws on tobacco that make use of decades of research on the impacts of policy on tobacco use." (Brownson, et al., 2009, p. 1578)

IV. The Third Domain

The third domain or that of 'outcome' is reported to have the objective of documentation of the "potential impact on policy." (Brownson, et al., 2009, p. 1578) Data sources for this third domain are reported to include systems for surveillance and "natural experiments tracking policy-related endpoints." (Brownson, et al., 2009, p.1578) Examples of the third domain reported by Brownson et al. (2009) include those of: (1) tracking changes in rates of self-reported seat belt use in relation to the passage of seat belt laws; and (2) describing the use of cost-effectiveness of child immunization requirement. (p. 1578)

V. Adoption of Public Health Legislation Banning the Use of Trans Fats in Restaurants and Bakeries Nationwide

According to the Centers for Disease Control and Prevention (2014) Trans fats were "created by chemists using a food process known as hydrogenation, where liquid oils are converted into solid fats. Trans fats, also known as partially hydrogenated oils, were intended to replace saturated fats which were found to contribute to heart disease. Unlike other dietary fats, transfats, are not essential to human health, do not promote good.....
