Evidence-based decision-making in public health is an objective method that involves seven steps: define, search, appraise, synthesize, adapt, implement, and evaluate. Research ethics are fundamental principles that guide the design and implementation of research.

Often, interventions outlined in research may not fit the designated community and require adaptation. The first step is to define the problem, usually as a PICOT question.

appraise — a part of the EBDM process that involves critically assessing each study for relevance and credibility to ensure the information provided is meaningful, trustworthy, and relevant. database — collection of information organized in a systematic method that is helpful when searching for sources of existing literature related to the topic of inquiry. search — a part of the EBDM process that involves reviewing the literature to examine what research is available to address a concern. adapt — a part of the EBDM process that determines if synthesized information can apply to the client (which may be a single person or a community) in discussion.
