I make a lot of decisions about how money is going to be spent, and I would like to always be able to back it up and say that this is proven, or evidence-based".
(Telleen & Simpson, 2006).
There are many definitions for EBPH and even some variations in its name, one variation is Evidence-informed public health.
“Evidence-informed public health is the process of distilling and disseminating the best available evidence from research, context, experience and using that evidence to inform and improve public health policy and practice” (By National collaborating center for methods and tools in Canada).
The practice of evidence-based public health (EBPH) is an integration of science-based interventions with community preferences for improving population health.
This Venn diagram shows the relationships among 5 concepts. Three circles in the middle of the graphic overlap with each other: 1) “Best available research evidence,” 2) “Resources, including practitioner expertise,” and 3) “Populations characteristics, needs, values, and preferences.” Overlapping these 3 circles and in the center is the circle “Decision-making.” This group of 4 circles is surrounded by “Environment and organizational context” (Jacobs, Gabella, Spring, & Brownson ,2012).

EBPH consists of 7 steps shown in the pie chart below.
In order to define the research question, four
components are to be identified into PICO framework
(which mainly serves clinical purposes).
For example, does smoking increase the
chances of miscarriage among pregnant women
within their first trimester of pregnancy?
P: Pregnant women (first trimester of pregnancy)
O: Miscarriage rates
